Abstract: The microbial desert sand brick has the characteristics of high strength, long service life, stable performance and simple construction. However, the lack of resources has led to a reduction in natural raw materials and the implementation of farmland protection policies. Alternative materials for clay such as tailings, shale, coal, and river powder have geographical limitations, high sintering temperatures, and complex production processes. Moreover, the resources of desert sand are all over the world, the feasibility of desert sand in engineering construction has been verified by many scholars. but the use of desert sand is seldom. In order to make full use of desert sand, this research takes desert sand as the main raw material. Microbial mineralization deposition technology is a new type of biomass cement preparation method. Mineralized deposition calcium carbonate can effectively cement desert sand brick particles, thereby improving the strength of the microbial desert sand brick. Therefore, this research group proposes to combine the method of microbial mineralization with high strength and low-cost desert sand brick, and use microbial mineralization to enhance the mechanical and durability performance of the microbial desert sand brick. In this research, the mineralization deposition efficiency of microorganism KJ01 and the performance of microbial mineralization enhanced the mechanical and durability of microbial desert sand brick were tested. Based on the study of the mineralization and deposition efficiency of microorganism KJ01, the performance of desert sand brick enhanced by microbial mineralization was studied. The effects of the mixed solution of microorganisms and nutrients and the concentration of bacterial solution on the mechanical properties and durability of desert sand bricks were studied. The results show that the mixture of microorganisms and nutrients can effectively increase the compressive strength, flexural strength and softening coefficient of microbial desert sand bricks, which are increased by 1.73%, 15.68%, 28.57% and 18.52%, respectively, reducing the water absorption and the weight loss after freezing and thawing were 2.7% and 19.39%, respectively.

Abstract: In this project, analysis of lead ore of Dalian region was carried out and then lead extracted from the ore. Lead is a grey colored metal, which is not found in free form, rather it is found in mineral with other metals such as Sulphur. Galena is the most commonly present lead ore. The technique used for the analysis of lead ore was ICP (Inductively Coupled Plasma). Lead ore was grinded to make powder with the help of pestle and mortar. This powder was taken as a sample and dissolved in concentrated HNO3 and aqua Regia separately for the preparation of solutions. Aqua Regia is a mixture of HNO3 and HCL with molar ratio 1:3 respectively. Ore was digested by heating in microwave oven in case of HNO3 and at hot plate in case of aqua Regia. After digestion, solutions were filtered and diluted with distilled water. Nebulizer of ICP converts the solution to aerosol, which was analyzed and detected. It gives the composition of metals in the ore. Lead was present in large quantity in the ore, which was taken for analysis in this project. For extraction, lead was heated in a furnace with a limestone in the presence of coke, which acts as reducing agent and also used for the purpose of heat. Lead obtained from this method is 99% pure.

Abstract: adverse impact of coronavirus (covid-19) pandemic is becoming worrisome and perplexing not only to Nigerians but to the international community. This has heightened the fear; thereby threatening the foundation of economic development. This study takes a critical look on measurement of the levels of safety or risk indices of all the 20 affected state on a logarithmic scale. From computation/analysis it shows that the state with largest number of infected persons/cases has the highest risk of spread of the COVID-19. Every unit increase in the incidence Safety Index corresponds to a Risk decrease by a factor of 10. The risk and safety indices sum up to a value of 10 and their values are defined over the interval [0, 10]. This study presents a better understanding and awareness of likelihood safety and risk assessment for the hazardous diseases. We recommend that, the identities of the infected persons should not be hidden even for the fear of stigmatization due to the consequences associated it. The Useful insights for the allocation of resources, remedial actions, monitoring and control strategies to prevent/curtail the dynamics of (covid-19) disease spread.

Abstract: This paper introduced the in-plane and out-of-plane instability numerical analyses of the H-section cold-formed steel arches. To validate the accuracy of the finite element modeling method, the comparison between various finite element methods were conducted. Utilizing the finite element analysis software ABAQUS, eight sets of H-section cold-formed steel arch models with different lateral brace spacing are established. Based on the finite element results, linear and non-linear buckling analyses was performed. The results indicated that the bracing spacing has little influence on the structural stability when in-plane instability is main instability mode for Hsection cold formed steel arches. While, when out-of-plane instability is the main instability mode, the larger the bracing spacing of H-section cold formed steel arches is, the worse its structural stability is. It is also shown that wind load often plays a determining role in practical engineering, where inelastic and initial imperfection exists

Abstract: COVID-19 is a novel coronavirus, a pathogen that has caused a pandemic with an outbreak in Wuhan in Hubei province of China in late December of 2019. It belongs to Betacoronavirus genera and shares similarity with SARS-CoV & MERS-CoV. It consists of a single stranded RNA genome which is comparatively larger than other family viruses. Its origin is known to be from bats. It is transmitted from human to human via droplets or close contact and has incubation period of 2-14d. Symptoms are generally fever, cough and fatigue for mild cases, however it progresses to multi organ dysfunction, pneumonia, acute respiratory distress syndrome and even death. Asymptomatic people are also considered as potential transmitters. The virus has spike glycoproteins (S) that gains entry to the host cells by binding to receptors Angiotensin converting enzyme 2 (ACE2). Till now no drugs have shown promising results, and efforts are being made for a fast development of therapeutics. This review briefly describes the impact of COVID-19 pandemic.

Abstract: The present study examines the efficiency and productivity of 18 private commercial banks in Bangladesh by using a Malmquist Productivity Index (an extension of Data Envelopment Analysis) with a balanced panel data over the years 2013 to 2017. The empirical findings suggest that Bangladeshi private commercial banks have decreased their average annual productivity by 3.0% mainly owing to technical efficiency and technological change. However, technical efficiency decline is due to lack of management effectiveness rather than scale efficiency of the sample banks. The results of the study also indicate that only Eastern Bank Ltd. and Al-Arafah Islami Bank Ltd are found technically efficient during the study period, while remaining sample banks are categorized as inefficient. In the course of examining the productivity changes of the sample banks, this study found only 3 among the 19 banks used in this paper showed total progress in productivity, whereas sixteen banks displayed total decrease in productivity. The major policy implications are further discussed.

Abstract: Centrifugal impellers are a centre segment of aircraft engines. The machining nature of the impeller straightforwardly affects its service life and mechanical properties. However, the complexity of the impellor blade surface and the requirement for a high degree of accuracy in the finished product means that the process of manufacture is complicated by the need to afford unimpeded access for the cutting tool. This paper describes research into CNC programming and the use of simulations to control the cutting tools, reducing machining errors due to such factors as distortion, collisions and interference. This is especially important where delicate and intricate machining is required as in the example of centrifugal impellers described in this thesis. Therefore, multi-axis NC machining theory, tool envelope surface theory, error compensation principles, numerical simulation technology, post-processing development for five-axis CNC machine tool of dual turntable, simulation and optimization for NC machining of Centrifugal impeller, planning for machining process of impeller and other technical methods were comprehensively studied.

Abstract: Corona viruses are single stranded, enveloped group of viruses which contain RNA genomes. Disease caused by SARS-CoV-2 is termed as COVID-19 which has a nucleic acid identical to some of the beta coronaviruses identified in bats. First identified in Wuhan City, Hubei Province, China, it has been causing an outbreak in 210 countries so far with a huge death toll. The disease is seen to be fatal to human health causing symptoms like Sneezing, Runny nose, Cough, Watery diarrhea, Fever in rare cases, Sore Throat, severe pneumonia. WHO has declared the outbreak as pandemic. It has several adverse impacts including downfall of the world's economy. World's GDP is expected to fall by 2.8%. Along with worlds, Nepal's economy may stumble if the outbreak persists for long. Nepal’s economy is suspected to be facing a drastic compression as Asian Development Bank (ADB) has prognosticated a decline in GDP to 5.3% in fiscal year 2020, down from 7.1% a year earlier. Prolonged cessation in economic activities will result in permanent loss in the economy of the country. Steps with patience to battle the spread of the pandemic are in urgent need.

Abstract: Wetlands cover 5% area of Nepal. There are many natural and artificial wetlands in Nepal. Out of them, Jagadishpur is the largest artificial lake and important wetland, located in Kapilvastu district. Despite the high potential for tourism development and close proximity to the Lumbini World Heritage site, this lake is less known to national and international visitors. Thus, this study was carried out to assess the possibilities of eco-tourism around this lake. Household survey, key informant survey and focus group discussion were carried out to know the people’s perception, issues and challenges for tourism development. Collected data were analyzed qualitatively. Jagadishpur along with the other nearby historical places like Sagarhawa, Tilaurakot, Gotihaw, Niglihawa, etc. have a high potential for eco-tourism development. Bird watching was found to be most feasible, followed by the Jeep Safari and boating. Other ecotourism activities like Tharu culture, homestay can also be developed. However, poor tourism infrastructure development, marketing capacity of local people on visitor management, etc. have been addressed as the issues in the study area. However, people and stakeholders are willing to sort out this problem and willing to involve in ecotourism activities. It is recommended that awareness programs by providing various skill development programs and workshops related to tourism, the information center and involvement of the private sector in the promotion of ecotourism in and around the site.

Abstract: Ulcerative colitis (UC) is the chronic relapsing multifactorial gastrointestinal inflammatory bowel disease, which is characterized by bloody or mucus diarrhea, tenesmus, bowel distension, anemia. Iron-deficiency anemia (IDA) is the most common reason for anemia in patients with inflammatory bowel disease (IBD), especially in UC patients. However, the majority of those patients are not often treated. Blood loss cannot be matched by decreased duodenal iron absorption, creating a negative iron balance, which is very common in UC patients. More than a third of anemic ulcerative colitis (UC) patients are not tested for IDA and among those tested and management properly. Iron enacts a key part of hemoglobin in erythrocytes and of myoglobin in muscles, which in combination contain approximately two-thirds of the total body iron. Systemically by several mechanisms is regulated of body iron homeostasis, among which is the pivotal interaction of the liver-derived peptide hormone hepcidin with the major cellular iron exporter ferroprotein(FPN). In assessment, all through states of iron deficiency, hypoxia and anemia, the synthesis of hepcidin is blocked which will boom serum iron stages. At the moment, oral iron therapy is typically desired for sufferers with quiescent IBD and mild iron-deficiency anemia. Nonetheless, restrained records are available on premier therapeutic begin and cease factors for treatment of anemia. But, extra prospective studies are nevertheless warranted to decide the most useful therapy in complicated conditions consisting of UC. This article will focus on the new insights into the IDA in UC.

Abstract: The study objective is to investigate the degree and type of anemia in patients with active Ulcerative Colitis(UC). Methods: Retrospective investigation of clinical data of UC patients admitted to the department of gastroenterology of the second hospital of Hebei medical university from March 2014 to January 2018. 152 patients with ulcerative colitis and 44 controls were included. According to the Improved Mayo Scoring System and Montreal Classification, UC patients were further divided into different group. The currently used World Health Organization (WHO) definition of anemia applies also to patients with UC. Statistical package for social sciences (SPSS) software was used for statistical analysis. Result: The prevalence of anemia in the ulcerative colitis patients was higher as compared to the controls (58.6% vs 21.4%, P 0.01). The prevalence of anemia in females in ulcerative colitis patients is higher as compared with the males (P=0.017). But there is no different in ages. In the ulcerative colitis patients having anemia, 60 cases (67.42%) had mild anemia, 27 cases (30.34%) had moderate anemia and 2 cases (2.25%) had severe anemia. Microcytic anemia was 40.44% (36 cases), normocytic anemia was 44.94% and macrocytic anemia was 14.62%. In the UC patients, mean corpuscular volume (MCV) is smaller than that in the controls (P=0.014) and red blood cell distribution width(RDW-CV) is bigger (P=0.036). There was no significant difference between the range of UC and anemia. However, the more sever of UC, the more sever of anemia. Conclusion: 1.

Abstract: Potentially sensitive materials have structural strength to tolerate loads be disposed to shrink dimension. the target of existing study is to associate the compressive strength of two material (AU5GT and AS7G06), which are utilized in diverse structural applications At quite few heat treatment sequences, it's problematic to conclude the compression strength of subsequent aluminum mixtures. Specimens are heat treated first as per premeditated progressions, later compression testing is implemented. Compression test is piloted in accordance with ASTM E9- 09 standard method on three samples with and bereft of heat treatment for separately sequences. Solution zing on trials is ended at perpetual period and temperature to achieve homogenization. Then, the aging treatment is conceded at diverse heats from 100 to 200 ° C (different intervals) for a particular period of your time to perceive the influence of the rigidity of the precipitation and thus increase the resistance. Sample compressive strength is decided using Universal Testing machine for every heat treatment cycle. The heat-treated AS7G06 displayed insignificant distortion, but the heat-treated model revealed enlarged AU5GT aluminum composite strength. Since slush, because it's very difficult to emerge as a rise in temperature precipitation, results in the harder areas of whole grains. Unsurprisingly, hardness also showed a rise in proportion. Analyze the fracture surface employing a stereomicroscope and a scanning microscope (SEM) to seek out the last sort of brittle, soft or transient fracture (combination of brittleness and ductility).

Abstract: In 1994, the Chinese film industry was opened to the world. The government transformed the most important propaganda means of the Party into a commercial culture industry. Though, the state still controls the industry by using cultural protective policies to not only protect domestic industries but also protect the distinctive nature of the culture from global intervention. Nevertheless, as an unexpected case in the globalization aftermath, the Chinese film industry not only wins over the imported movies in the domestic film market but also the second-largest film market in the world. Accordingly, the thesis examines the elements that contribute to this such incredible success. Locating the Chinese film industry in the world within globalization, this thesis discusses the following research questions: What are the elements that help the Chinese film industry in achieving its success? To answer the question, there are three sub research questions that the paper would study in each chapter of the paper. Did the protectionist policy helps to develop the Chinese film industry under the influence of Hollywood movies? What are the characters of Chinese blockbusters? What are the contributions of the market’s factors according to Litman’s model that help the Chinese film market share surpass Hollywood movies? By using a historical-political analyzing method to approach the research question, the thesis was organized as 3 main chapters. The findings are found by conducting an in-depth analysis of China’s film policies based upon reliable data incorporating with a historical perspective. Popular protective policies such as quota policies, screen policies, subsidies contribute to supporting the film domestic market to have space to develop while the censorship was the only policy that effectively helps protect the domestic culture from Hollywood’s influence. Analyzing the success of the movie “The Wolf Warrior 2” reveals “Chinese patriotism with Hollywood characteristics” which could be the new theme for Chinese blockbuster to develop in the future. The contribution of private corporations in the industry still limited to the exhibition market. Broaden the presence of private companies in other aspects such as production and distribution would help the Chinese film market stronger and more integrated, which is important to stand out in the world film market.

Abstract: The major objective of this thesis is to examine the impact of GSP on the Sri Lankan export sector. Trade data come from the Report of Central Bank Sri Lanka dataset and cover all the available bilateral exports between 25 top export countries over the period 1985 – 2005. Overall, markets receive at least 83% of Sri Lanka's exports. The estimation covers 25 countries with one dependent variable and 16 explanatory variables and all variables are expressed natural logarithm. Trade values are reported in millions of dollars. Population, GDP, REER, and Land Size data have been obtained from a standard source, The World Bank 's World Development Indicators. The study used CEPII data for the country-specific variable: distance. The GDP of Sri Lanka and its trading partners, Population of the provider countries, had a positive influence on Sri Lankan's exports. These results had a positive impact on Sri Lanka's GDP exports, which resulted in higher returns. The results also suggested that Sri Lankan exports were positively influenced by an increase in GDP in the providers' countries; the higher the income in providers' country, the greater the volume of Sri Lankan exports. The distance, REER and Land variables between Sri Lanka and the providers' countries had its expected sign. The GSP variable is highly significant and positive. This implies that the providers' country that has GSP with Sri Lanka can affect Sri Lanka's exports.

Abstract: Reconfiguration antenna and phase, there is a need for “reconfigurable antenna” in driven by various industries aviation, telemetric, satellite communication, etc…But above all wireless communication and defense surveillance lead the new trend. With 5G in our meets a new wireless communication infrastructure requires very high radio frequency exceeding 20 GHz; at these frequencies radio waves start to behave like light beams. They are most easily blocked by obstructing structures reflect on surfaces, etc…the results is none uniform coverage throughout the city making difficult for mobile device maintain good reception. The problem it even worse when mobile devices transmitting their signals back to the station because they tend to use low power transmitter when the signal is transmitted it might not make it to the receiving tower that also depend on where the mobile device is located. A reconfigurable antenna can be made by putting small micro switches between elements of a complex antenna buy turning the switches on and off different part of the antenna are allow to radiate providing changes in the radiation pattern by quickly switching the antenna elements on and off the antenna move between several radiation pattern and find the one with better reception this makes it “smart”

Abstract: The petrographic study has been well carried out in order to understand the mineralogical and geochemical characteristics of the Nari Formation at “Gandri Jabal” section near Nooriabad, Jamshoro. The formations were found to be mainly composed of sandstone, limestone, shale and variegated clays in the studied section. Sandstones are compact to semicompact, ferruginous, fine to coarse grained and range from pinkish, reddish, brownish to camel in color. It was unusual that one bed of camel colored limestone with maga fossils was observed in the upper part of the formation. Petrographic study of the Gandri Jabal Section, Upper part of Nari Formation on the texture of most of the samples is medium to coarse grained as well as the shape of the grains is angular to sub-angular. Dominant cementing material is calcite along iron oxide. It was further justified by geochemical analysis of major elements through automated Scanning Electron Microscopy Energy Dispersive Spectrometer (SEM-EDS), that the highest peak was silicon (Si), the second dominant peak was of calcium (Ca), and a third dominant peak was fermium(Fe). This mean that the major mineral constituent was quartz and within the sandstone the cementing material is calcite and iron oxide, and highly calcium (Ca) bed found means that major mineral constituent was Calcite within mega fossils limestone. These finding demonstrate that majority of the lithologic units of this formation are daltatic or beach and one bed is in Marine environment as considered by earlier workers. The samples having higher proportion of quartz grains belonging to quartz arenite category. Hence it is concluded based on the shape of detrial quartz grains, that the source of these sediments neither came from northern Himalayan nor from Indian shield, but very likely came from the western highlands and on the basis of the present rock fragments, we conjecture that source is igneous, sedimentary or metamorphic

Abstract: This work was conducted during the winter season of 2017-2018 to determine the appropriate seedlings transplanting time at two AEZs on the yield and quality of onion bulbs (BARI Piaz-1). There were six levels of seedlings planting time such as T1: 15 November, T2: 30November, T3: 15 December, T4: 30 December, T5: 15 January and T6: 30 January and two Agro-ecological zones (AEZs) such as L1: Bogura (AEZ-4) and L2: Lalmonirhat (AEZ-2) in the experiment. The field trial was placed at the experimental farms of Spices Research Centre, Bangladesh Agricultural Research Institute (BARI), Bogura and Spices Research Sub-Centre, BARI, Lalmonirhat. The experiment was laid out in a randomized complete block design of factorial concept with three replications. The results revealed that seedlings transplanting times, AEZs and their combined effects had significant effect on the parameters studied with minor exception. The values for plant growth, onset of bulbing, incidence of bolting, maturity date, splitting & bolter bulbs and dry matter content of leaves were gradually decreased with the passage of transplanting time. Longer cold period facilitated for increasing of bolting at earlier stages of transplanting. But yield attributes and yield were increased up to the third transplanting time. After that it was decreased. However, due to inferior incidence of bolting, transplanting on 30 December exhibited the best performance for producing quality bulbs. Because of higher temperature and long day length, no bolting was occurred from 15-30 January. For the same reasons, transplanting seedling on 15-30 January gave poor yield of onion. Onion bulbs bolted bear hard centers that deteriorates quality and also decreases the market value of that bulb. The higher values of plant growth, onset of bulbing, incidence of bolting, splitting & bolter bulbs were obtained from Lalmonirhat due to longer cold period prevailing in Lalmonirhat. Hence, considering the incidence of bolting, Bogura performed better for the yield attributes, yield and quality of onion. The combined effect of 30 December and Bogura gave the best quality of yield attributes and yield of onion. Differences in weather conditions between onion growing locations affect bulb quality. The experiment may be repeated at more AEZs to confirm the consistent results.

Abstract: The garment industry has become a pillar of Bangladesh's economy. More than 3 million people work in the garment and textile industries. The ready-made clothing industry (commonly known as RMG) accounts for nearly 81 per cent of Bangladesh's total exports. In countries that have not traditionally worked outside the home, this sector was the first to provide large-scale employment opportunities for women. However, the diversity of these challenges and the difficulty to overcome raises the question of the sustainability of their current growth and its future growth. The sustainability of this large industrial sector must be promoted. While the world's clothing markets and companies focus on environmentally friendly products, Bangladesh's clothing and textile industries go far beyond it, posing a risk of losing the world market. The time has come for a special strategy and a sustainable approach. The study highlights the measures that need to be taken to achieve sustainability. In terms of the working environment, Bangladesh's garment industry is currently facing enormous challenges. Fire accidents, recent building collapses, minimum wages and many other problems are closely related to the sustainability of the textile and garment industry. At the same time, China is the world's largest producer of textiles and RMG. Although they have had such problems recently, they have taken enormous steps to alleviate all these major problems associated with the textile and garment industries and to promote their industrial and national economies. Therefore, the purpose of this paper is to find out the current problems and strategies to solve them according to the existing practice of China's textile industry.

Abstract: Since ancient times, as a national symbol and cultural development, wedding dress plays a very important role in national research. In addition, people can better understand the history of human society and explore the basic laws of the development of human society through a large number of gorgeous wedding dresses. In the development of human society, many wedding dresses have experienced various changes. As a basic model, the "six etiquette" has not changed much in China, and it is still the essential core of marriage customs. In Bangladesh, effective marriage should experience proposal, choose a day and hold a wedding. The most important aspect of marriage is wedding dress. This paper will discuss the different aspects of women's wedding dress in the two countries Chinese woman’s wedding costume and Bangladeshi women’s wedding dress Saree. Due to different cultural origins, religious concepts and geography, there are different procedures, different clothes, different activities, different colors and different wedding ceremonies between China and Bangladesh. Due to cultural exchanges, China and Bangladesh have some similarities and differences in wedding dress. This article will also discuss some similarities and differences and absorption of wedding culture between China and Bangladesh. By comparing these processes with some related stories, we can easily find the difference. Generally speaking, women's wedding dresses of the two countries give us the impression of romanticism, freedom and fairness.

Abstract: Railway is considered one of the cheap, eco-friendly and comfortable means of transportation. They are demolishing the natural sceneries, led to death or declining the wildlife inhabitants and producing an intolerable noise. The noise produced by railway is of high frequency and sound pressure level (SPL). The peaceful sound of the park and the high speed railway noise are recoded to evaluate their SPL by the sound spectrum curves. The sound pressure level (SPL) of the peaceful environment is around 42 dB and for the high speed train running at 300 km/h has a value of about 82 dB. The noise generated by high speed railway with high SPL produced inhibition phenomenon in the growth and the production of the microbial. Also, the exposure of railway noise disturbing the routine of human beings and caused many diseases. The impacts of the high speed railway noise exposure on the microbial can be described experimentally by using acoustic chamber. Low frequency sound exposure produces positive effects while higher frequency sounds (noise) exhibit inhibition and destructive phenomenon in the growth rate of the microbial. In literature, most of the authors studied on the effects of audible sound on the microbial, but there is not much work has done to investigate the effects of railway noise exposure on them. This article presents the impacts of noise generated by railway on the human and microbial.

Abstract: This paper aims to review the current improvements in the grinding process of spices. Grinding is an important step in postharvest processing of spices. Therefore, it requires special attention in preserving aroma and flavor compounds present in them. Overall temperature increases significantly during grinding which results in loss of a considerable fraction of aroma and flavor components in spices. During grinding, quality of spices is often limited by thermal damage to the ground component. The amount of heat entering the workpiece must be controlled in order to avoid thermal damage. This is one of the main limitations of the grinding process which is to be important to understand how to overcome the factors which affect the grinding temperature. There are several methods that are efficient for different types of spices available in the world. Therefore, it is important to use correct technologies and measures to secure the quality of the spice product.

Abstract: The present investigation was intended to establish an effective protocol for direct shoot regeneration as well as root induction of Citrus sinensis using seed germinated shoot tip and nodal segments. Surface sterilization of explants was attributed with NaOCl (Sodium hypochloride) in shoot tip and nodal segments for successful contamination free culture. For direct shoot proliferation, nodal segments and shoot tips showed effective results when it cultured aseptically on MS (Murashige and Skoog) medium containing different concentrations and combinations of BAP (Benzylamino purine), GA3 (Gibberellic acids), NAA (Naphthalene acetic acid) and IAA (Indole acetic acid) the best result was observed in the combination of 1.5mg/l BAP+ 0.2 mg/l GA3. The explants were inoculated on MS medium supplemented with 8g/l Agar and 30g/l sucrose, different combination and concentration of plant growth regulators was used for plantlet regeneration. Root induction has also done here using various concentration of IAA hormone. The highest number of root induction was found to be MS containing 2.0mg/l IAA. Induced roots were elongated properly at the same hormonal concentration after two weeks of inoculation. From the above findings, it is suggested that different hormonal concentration and combination has significant effect on the propagation of sweet orange plant. The established protocol would be helpful for direct plantlet regeneration as well as proliferation of this valuable fruit crop plants.

Abstract: To overcome the shortage of energy, Pakistan must develop its own indigenous energy resources, such as hydropower, solar and wind energy. Pakistan is in an area of one of the highest solar streams in the world. This great potential can be exploited to produce electricity, which can be presented to cold communities in the hilly areas of the north, south, and western deserts. Consequently, this paper discusses the situation and prospects for the use of photovoltaic energy in Pakistan. In this energy scenario, the PV energy shares are in the range of a fraction of a percentage compared to total conventional energy supplies. Main emphasis in this study has been given on presentation of data about photovoltaic energy (PV) installations in the country, the on-going activities, development projects, PV planning and accomplishments of public sector PV institutions and organizations. Fortunately, Pakistan is among those regions where sunlight warms the surface throughout the year and therefore has a strong force of generating solar energy.

Abstract: Nowadays, the uses of renewable energy resources are growing rapidly. Several renewable resources such as hydro, wind, solar and tidal are commonly used all over the world. Following this trend, the implementation of large area solar arrays is considered to be necessary. Several design methodologies and approaches have been accessible in order to obtain maximum efficiency of solar panel supporting structure. In this study, Finite Element Method (FEM) was established to investigate the impact of various wind loads on the structural reliability and strength of solar panel supporting structures. The wind speeds of 20 m/s, 25 m/s, 30 m/s, 35 m/s and 40 m/s were used for the analysis of solar panel supporting structure. Wind loads were also calculated by mathematical approach. The results show that solar panel structure was significantly affected by wind loads applied on the surface of solar PV module. The results obtained from the FEM analysis that total deformation and maximum equivalent stresses were increased by increasing the wind loads. The maximum value of equivalent stress can be found at joint sections of solar panel supporting structure and total deformation is higher at centre of the structure as well as at base of the structure. The maximum and minimum value of equivalent stress 62.866 Mpa and 15.75 Mpa can be found at 40 m/s and 20 m/s respectively. Similarly, maximum and minimum value of total deformation 0.3631 mm and 0.0911 mm can be found at 40 m/s and 20 m/s respectively. The knowledge of stress distribution and deformation play a vital role for structure designs, stability and strength of hydro solar panel supporting structure.

Abstract: Individual countries and panels of countries have been studied the association between financial development and economic growth using different methodologies. There are three kinds of results — first one unidirectional relationship second one bidirectional relationship and third one no relationship at all. Studies of Sri Lanka have insufficient; there have different ideas of conclusions and one unique method they have applied the papers. The purpose of the paper is to realize the relationship between financial development and economic growth in Sri Lanka. The annual data sets are used in 1947 to 2016 period of the Sri Lankan economy. This thesis has ten variables that can be obtained from the Central Bank Reports of Sri Lanka from 1950 to 2016. In this thesis, the unit root test, the vector error correction model (VECM) and the Chow test method are used to perform the tasks. In between short and long-term decisions, it can be used VECM and, eventually, by economic or political policy changes or unexpected economic shocks, can be used chow tests. The study found that the causal relationship between Money Supply (M2), Loan (LOAN), Investment (INVEST), Government Debt (GD), Current Account Balance (CAB), Consumer Price Index (CPI), Average Weight Deposit Rate (AWDR) to the Gross Domestic Product (GDP). There are no short-term causal relationships from Loans (loans), Government Debt (GD), Current account balances (CAB), Consumer Price Indices (CPI) and Average Weight Deposit Rate to the Gross Domestic Product. The conclusion of the objective reaffirms that M2 and economic stability are of great importance in Sri Lanka. The factors that affect Sri Lanka's long-term financial development and economic growth are then identified. Developing Sri Lanka as a Financial Center, it will be a catalyst for economic growth and greater international trade. So, involvement Financial Center and Port City, Sri Lanka can be maximized their economic growth and financial development.
