Abstract: This research study was conducted to know the effects of positive reinforcement on students academic performance. For this purpose a sample of 50 subjects (20 female & 30 male) was selected having the same socioeconomic background with no cultural differences. All of the subjects were taken from a government school their age ranges from 9 to 11 years having mean age of 9.8. They were all 4th and 5th graders. It was hypothesized that positively reinforced students will score higher on recalling non sense syllables through free recall test. Results of the study confirmed the hypothesis and a significant difference was found between the scores of experimental and control groups with a mean of 0.5 for both experimental and control groups and value of “t” was 2.50 significant at 0.5 level.

Abstract: This study on pressure sensors was conducted in order to determine which design yielded the device with highest sensitivity. Seven different microcantilever shapes have been used and their behaviour towards applied pressure has been studied to find out which shape showed the most displacement for the same applied pressure. A pressure of 1000 kPa was used for each model. A solid cylindrical silicon structure was used as the piezoresistor. The change in resistance of the piezoresistor was calculated due to applied pressure. The gauge factor was calculated for each model and thus the model with the best sensitivity was determined. All simulations were done in COMSOL Mutliphysics v4.4. The results indicate that the 1 µm single-crystal silicon rectangular (slotted) microcantilever sensor showed maximum sensitivity among the sensors studied.

Abstract: The worldwide escalation of antimicrobial resistance to conventional medical antibiotics is a serious concern for modern public health and welfare. Emergence of multidrug-resistant (MDR) strains among microbial infections threatens the effectiveness of current treatments and gradual decrease in clinical efficacy of antimicrobials causes thousands of deaths every year. The problem is spreading and progressing day by day at a rapid rate affecting most part of the world. To cope with this problem new improvements in present methods and novel strategies are urgently needed. Scientists and researchers around the world are searching for alternative approaches. One of the proposed methods to cope with multidrug-resistant pathogens is the use of alternative antimicrobial treatments, which include natural antimicrobial substances such as plant essential oils.Essential oils have a long history of use in the treatment of infectious diseases. From ancient times they have been found effective against a range of microbial infections. Owing to their antimicrobial activities, essential oils represent a promising solution for overcoming antimicrobial resistance. The scientific testing of essential oils against microorganisms has been taking place for many years, with the majority of the work seeking out effective solution to confront the growing multidrug-resistance. In recent times, many essential oils have been discovered to have significant cytotoxic, antibacterial, antiviral, antiparasitic and antifungal activity against a wide range of pathogens.This review is written with the purpose of giving an overview of the potential of essential oils to combat antimicrobial resistance.

Abstract: A social robot is an autonomous robot that has to be able to express emotions, communicate with high level dialogue, and use natural cues. To make the robot more interactive and communicative, lots of sensors and modules has to be used along with its moving mechanism. And thus the system becomes further more complex and expensive. This is why a design of social robot using a combination of embedded systems has been represented that can take live video surveillance and intelligent enough to solve complex mathematics. By using internet as the robot’s source of information and Android phone as the robot’s sensory and control system partially, and adding them all to the robot’s embedded system wirelessly, it has made the robot more advanced and intelligent, hence reduced cost of construction by a lot.

Abstract: This paper analyses the perception of fisher folk at Senya Beraku about the effects of climate change and its impact on their livelihood. Senya Beraku is in the Central Region of Ghana were majority of the natives are engaged in fishing profession for their living. Interview schedule was employed to generate primary data from one hundred (100) respondents of whom sixty-two (62) were fishermen and thirty-eighty (38) were fishmongers. Questionnaire was structured base on climate change on rainfall changes (amount and patterns), sea water temperature changes, sea water warming changes, sea air temperature changes and sea air intensity changes over the past twenty (20), ten (10), five (5) years and current seasons of fishing respectively. From the results, majority of respondents perceived that over the past 20 and 10 years, rainfall pattern and amount, sea water temperature, sea water warming, sea air temperature and sea air intensity had been normal, cold, low and cold respectively. Moreover, majority of fisher folk indicated that over the past 5years and current fishing seasons had experienced intense reduction in rainfall amount and pattern, warmer sea water temperature, higher sea water warming intensity and warmer sea air temperature. Climate change impact on parameters considered have caused severe reduction in fish catch capacity and this has decreased livelihood status of fisher folk. Due to lack of education, fisher folk attributes these changes to natural events. These can be avoided by improving knowledge of fisher folk on inappropriate fishing practises that affect the climatic conditions of the sea.

Abstract: Despite efforts by government to increase access to secondary school education in Malawi, enrolment rates remain minimal in comparison to primary school completion rates. This is largely attributed to limited space in and availability of public secondary schools in the country. Against this background, addressing the question of admission into the available public secondary schools remains critical. This is especially in view of access versus quality in the education that is provided to children and the context of Malawi as a resource-scarce country. The current secondary school admissions policy results into categorization of public schools through which selection of successful primary school candidates is made. This leads to a stratification that seems to have an everlasting bearing on the students undergoing secondary education through to university, adversely impacting greatly on social mobility. This paper examines the impact of the admissions policy on education, relating it to the legitimatizing of the social stratification that results thereafter in the society.

Abstract: Abstract:Four experimental diets were used for four treatments viz.T1 (SD+1.95% lysine of diet), T2 (SD+2.05% lysine of diet), T3 (SD+2.15% lysine of diet) and T4 (Control, SD+0.00% lysine of diet) with each having three replicationsto understand the effects of lysine on growth, histological changes in liver and intestine of GIFT strain of tilapia (Oriochromisniloticus).Forty-eight days old and almost uniform tilapia fry were stocked in experimental cemented tanks and fed twice a day with experimental diets containing different doses of L-lysine for 40 days from May to June 2016 and then checked the growth and health status of experimental fish atevery 10 days interval. After feeding trial results showed that, the body weight was significantly increased 13.04±0.3gm (p<0.0001) with T2 treatment followed by 10.58±0.14gm, 9.86±0.07gm and 7.79±0.05gm with T3, T1 and T4, respectively.In addition to that, the body length was significantly increased 8.63±0.81cm (p<0.0001) with T2 treatment followed by 8.59±0.08cm, 8.42±0.12cm and 8.1±0.06cm with T3, T1 and T4, respectively. SGR of fish were 2.41±0.004, 2.52±0.04, 2.45±0.07 and 2.07±0.04% with T1, T2, T3 and T4, respectively. Histological observation of liver and intestine were carried out with T1, T2, T3 and T4 treatment where the microvillus fold and height in intestine were comparatively higher in T2 treatment, but there were no vacuoles and infiltrations in T2 treatment compared to T1, T3 and T4 treatments. The present findings revealed that 2.05% supplementary lysine for Tilapia might be a good promoter for their growth and culture.

Abstract: Abstract:Nowadays, tuberculosis (TB) still remains one of the deadliest communicable diseases despite the medical advancements in recent years. Although many laboratory methods have been developed to tackle this issue, it is important to distinguish tests that detect active TB from latent TB. In most infected people, the disease remains clinically asymptomatic and microbiologically inactive. Many years after the initial infection, patients develop active TB through endogenous reactivation of the latent infection at some point in their life. Detecting patients with either form is therefore, an important component of the control of the disease. A good understanding of the effectiveness and limitations of each method will contribute to enhance the diagnosis of the disease. This review summarizes the performance of diagnostic tools in the detection of latent tuberculosis infection (LTBI) and active TB; and also discusses the way forward for future methods of the diagnosis of active pulmonary TB.

Abstract: Among the Indian women novelists, Jhumpa Lahiri is primarily concerned in her novels with the psychological crises in the lives of immigrants who are subjected to physical and psychological sufferings in a foreign land. The novelist has showed her skill in projecting the agonized mind of the alienated men and women. Her portrayal of characters in the novels invariably bears authenticity to her feminist approach, outlook and perspective. The theme of Displacement plays a key role in her novels. The keen observation of the life of immigrants and the interest in the study of their inner mind are evidence by the portrayal of her characters. Lahiri, being a woman dive deep into the inner mind of the repressed women and bring to light their alienation and loneliness which are the outcome of women’s psychological and emotional imbalances.

Abstract: This study was undertaken to evaluate the performance of Aluminum-casted cook stoves using Water Boiling Test protocol with the Laboratory Emissions Monitoring System (LEMS). When the newly designed improved cook stove construction and operation is more or less similar to the traditional stove, people are ready to accept the stove. The performance of the stove has been very good encouraging compared to traditional stoves, hence has been great concern to manufactures and engineers. Currently, in Ghana the stove is readily accepted and appreciated by end users nevertheless its safety is questionable. In this study, the thermal efficiency of the stove compared to traditional stove is very improved. Based on the findings, advanced researches on manufacturing and production should be could carried out on the stove to enhance its performance, emissions, efficiency and safety to be of great use in most developing countries such as Ghana.
