Poor academic performance of most public primary schools in Suna East Sub-County is a serious challenge in Migori County. Out of five zones in the sub-county, there was low learning outcome in the assessment score with a mean standard score of 250 out of 500 marks for the last five years. The objective of this study was to investigate the influence of teacher professional knowledge and application on academic performance. The study used a survey design and both qualitative and quantitative methods of data collection and analysis. This study was based on two theories; the goal setting theory by Edward Locke and Expectant theory by Vroom. The study had a population of 65 head teachers, 65 deputy head teachers and 500 assistant teachers in public primary schools in Suna-East Sub-County Migori County. Krejcie and Morgan table was used to obtain a sample size of 56 Head teachers, 56 deputy heads, and 217 assistant teachers. The study also used both questionnaires and interview schedules to collect data. Validity of the research instruments was determined through open discussion with the supervisors of Kisii University. Reliability of the research instruments was established through test re- test method using questionnaires and interview schedules results. The data collected was analyzed using statistical package of social sciences (SPSS) version 21 to generate descriptive statistics in a correct and informative way. This study would be significant in the field of education in enhancing quality education by the educators. The finding revealed that most of the teachers 163(83.9%) indicated that they think that professional knowledge is essential in enhancing teaching outcomes, only 33(16.1%) who did not consent. Professional knowledge is viewed as key in evaluating teachers teaching outcomes. It includes all professional record kept by the teachers to enhance learning and academic outcome. The study recommended maintenance of professional records at all times. It concluded that a teacher should ensure there is effective syllabus coverage by attending all lessons as per the school timetable. The researcher paid keen attention to research ethical issues and got the informed consent of the respondents and guarded against plagiarism and ensured confidentiality.

The 2019-novel corona virus (nCoV) is a major source of disaster in the 21th century. However, the lack of specific drugs to prevent/treat an attack is a major need at this current point of time. In this regard, we conducted a systematic review to identify major drug gable targets in corona virus (CoV). We searched PubMed and RCSB database with keywords HCoV, NCoV, corona virus, SERS-CoV, MERS-CoV, 2019-nCoV, crystal structure, X-ray crystallography structure, NMR structure, target, and drug target till Feb 3, 2020. The search identified seven major targets (spike protein, envelop protein, membrane protein, protease, nucleocapsid protein, hemagglutinin esterase, and helicase) for which drug design can be considered. There are other 16 nonstructural proteins (NSPs), which can also be considered from the drug design perspective. The major structural proteins and NSPs may serve an important role from drug design perspectives. However, the occurrence of frequent recombination events is a major deterrent factor toward the development of CoV-specific vaccines/drugs.

Calcifying Odontogenic cyst (COC) or Gorlin cyst is an uncommon benign cystic lesion which develops from the odontogenic epithelium. According to WHO it is classified under developmental Odontogenic cysts. They occupy a spectrum ranging from a cyst to an odontogenic tumor. It most commonly involves the anterior region of the jaws. The characteristic feature of COC is the presence of Ghost cells within the epithelium that has a propensity to calcify. In this paper we illustrate a case of COC in a 14-year-old girl, and the investigations done to arrive at the final diagnosis.

Among the branchial cysts, those arising from second arch, which appear in the mid neck are the most common. It is followed by cysts arising from the third and fourth arch, which appears in the lower neck, supraclavicular or suprasternal location. But branchial cysts presenting as a mediastinal mass is very rare. Here we present four different clinical presentations of branchial cysts with their gross morphology and microscopic findings.

Persistent organic pollutants (POPs) are toxic chemicals which affect the health of human beings and the environment adversely. These pollutants could be transported by wind and water. They could affect people and animals in other countries far from where they were generated initially. POPs persist in the environment for a long time before they are degraded. They bioaccumulate in organisms through the food chain. These chemicals include the organochlorine pesticides and other halogenated organic compounds such as polychlorinated biphenyls (PCBs) and dioxins.The aim of this review is to examine the transport of these pollutants from their point of application and look into their effects on human health. Recent studies reported the gradual introduction of these banned chemicals under different trade names into the environment. Therefore, this review will re- enlighten the public on the dangers in the transportation as well as the harmful effects of these pollutants as they also biomagnify in human. Proper measures on the handling, usage and regulation of these contaminants especially the synthentic organochlorine pesticides should be rekindled worldwide.

The Monpa tribe of Arunachal Pradesh is one of the important indigenous tribes of the Eastern Himalayas whose livelihood and food systems are intricately linked with the ecological and cultural landscape of the region. The present study focuses on the traditional food habits and livelihood patterns of the Monpa people with a view to understanding the interdependence of natural resources, subsistence practices and socio-cultural traditions. The diet of the Monpa people consists of locally available cereals, millets, vegetables, fermented foods, dairy products and meat, showing adaptation to the high altitude climatic conditions. Indigenous knowledge is important for food preservation, seasonal consumption and sustainable resource use. However, the report also notes the emergence of changes from market integration, infrastructural development and changing consumption patterns which are slowly beginning to influence traditional livelihoods and food practices. Understanding these dynamics is important to frame development policies that are sensitive to the culture, ensure food security and promote sustainable livelihood strategies among the Monpa community. The study underscores the need for maintaining traditional knowledge systems alongside modern interventions for inclusive and sustainable development.

The aim of this study was to investigate the level of essential and non essential metals in Bulla of Ensete ventricosum and soil samples in West Showa Zone. K and Na were analyzed using FAES, Ca and Mg were determined complecometric titration method and the other metals with FAAS after appropriate quality control measures were undertaken to verify and maintain the quality of the data generated. The optimized wet digestion method for Bulla and soil analysis was found effective for all of the minerals and as it was evaluated through the recovery experiment, a good percentage recovery 96.85% (Fe in Bulla) to 112% (Pb in soil) was obtained for the minerals identified. The results of this study showed that the average concentrations were ranged in order decreasing in (mgkg-1) 3366.28(K) >1881.57(Na) > 593.44(Mg) > 862.85(Ca) > 55.68(Fe) > 6.99(Zn)>3.09(Cu)>2.96(Mn). Cd and Pb were not detected for Bulla and 3521.11(K)>3497.85(Mg)>3461.59(Fe)>3294.93(Ca)>1096.89(Na)>(93.99(Mn)>16.74(Zn)>3.77(Cu)>0.26(Cd) for soil sample and Pb was not detected. The concentrations of the metals were also compared with recommended maximum permissible limits and some international reports; and found to be in a good agreement indicating no exposure risk of using the bulla and corm of Ensete ventricosumunder the current situation. Statistical test of significance using ANOVA revealed that there were significant differences (P<0.05) between the values of metals in the bulla and soil samples obtained from all the sampling sites except Zn and Fe for bulla and Ca in soil.

This paper aims to estimate the effect of Non-oil Exports on GDP, FDI in Saudi Arabian economy for the period between 1970 and 2019. Moreover, it investigates the causal relationship between Non-oil Exports, GDP and FDI applying the ARDL Bound test and Bootstrap Toda - Yamamoto (1995) causality test. The findings of this study suggest that Saudi Arabia followed an export-led growth path and that economic growth has a significant effect on the FDI growth process via export growth channels, in particular, non-oil exports. The overall findings of this study suggest that non-oil exports growth positively affects GDP in the Saudi economy, which in turn supports increased demand for FDI, when all things are considered equal. The results also show that an encouragement of non-oil exports is a necessity for an effective GDP, FDI in KSA. Therefore, in designing policies towards this direction, economy policy response lag need to be taken into. thus we suggest encouraging non-oil export activities in order to stimulate long-term economic growth in KSA this is by supporting increase demand for FDI. A favorable FDI would reduce the cost of production for producers in the non-oil sector. Thus, leading to a growth in the economy.

Objective: The present study was designed to evaluate the acute and chronic behavioral and antidepressant effects of aqueous extracts of GS leaves in standardized rats models of depression. Materials and Methods: Aqueous extracts of GS leaves were prepared, and phytoconstituents were determined using appropriate chemical analytical methods. Animals were divided into five groups: The control group received vehicle (saline water 10ml/rat). Amitriptyline (20mg/kg b.w., IP) was used as the positive control or standard group while the treated rats received GS (100, 200, and 400mg/kg body weight i.p). In the acute treatment study, a single dose was administered 30 min prior to testing. For the chronic treatment study, a single dose was administered daily for 14 days. In the chronic dose study, the behaviors of all groups were assessed for antidepressant activity 30 min after the last treatment dose on the 14th day. Different standardized depression models were used for behavioral tests to evaluate the antidepressant activity, such as forced swim test (FST), and tail suspension test (TST) test. Results: The preliminary pharmacological screening with acute dosing exhibited the antidepressant activity of GS, but its antidepressant activity was more enhanced after repeated dosing. In comparison with the acute studies, chronic dose studies displayed a significant antidepressant manifestation in the behavioral patterns when compared to the vehicle controls. Conclusion: The results obtained in this study suggest that aqueous extracts of GS may possess an antidepressant activity.

Nowadays, supermarkets are almost developed with much technological advancement. People purchase different items from the supermarkets and put them into a trolley because it is the easiest method used in supermarkets to carry goods. However, throughout the whole process of shopping, customer must push the trolley manually by their own effort and when it comes to the billing process customers must wait in long queues to pay their bills. This is a time wasting process due to the busy schedule of people. To avoid these problems the research groups have introduced an effective and highly advance system. To swamp these problems, Shopping malls use this technique as a strategy to increase the number of purchasers. In big cities, we can observe an enormous flash at shopping malls on weekends. This becomes even more when there is diversity of offers and discount. The prevailing billing system is a bit time consuming. So, we thought of inventing a remedial electronic product to catch-up with this problem. We call it “Human Guided Smart Cart for billing system”.

Introduction: Maternal RBC alloimmunization results from exposure and response to a foreign RBC antigen. Transplacental fetal to maternal hemorrhage is the most common cause of alloimmunization. Rh incompatibility can lead to either fetuses with hydropic features or non hydropic. The precise mechanism leading to the development of hydrops is not certain. All direct fetal sequelae of hemolytic disease relate to the development of anemia. In general, the fetus tolerates mild to moderate anemia well. However, metabolic complications develop as the anemia worsens. Because the RBC is the principal fetal buffer, a metabolic acidemia with hyperlactatemia develops in fetuses with severe anemia. Objective: To compare the difference in mean hemoglobin and hematocrit concentration between Rh-hydropic, non hydropic and control group and further based on severity of hydrops. Methods: A Total of 40 pregnant patients were enrolled which included 10 hydropic fetuses of Rh isoimmunised mothers, 10 non hydropic fetuses of Rh isoimmunized mothers. Control group included 18 Rh positive women without any fetal complication and 2 fetuses in women undergoing cordocentesis. Blood sampling was done at time of intrauterine transfusion and sent for estimation of hemoglobin and hematocrit in fetal blood. Pregnancies were followed up till delivery and fetal outcome noted. Result: Mean values of haemoglobin in hydrops group are 4.54g %, as compared to 6.65g % and 14.26 g % in non-hydrops and control group. Mean haematocrit in hydropic group is 13.91% as compared to 20.25% and 43.51% in non hydropic and control group. The mean haemoglobin concentration in mild hydrops was 5.17g % as compared to 2.7g % in severe hydrops. Conclusion: There was severe hemoglobin and hematocrit deficit in hydropic fetuses as compared to non hydropic and normal fetuses matched for the gestation age. Thus severity of anemia can be considered a strong marker for development of hydrops in Rh isoimmunized fetuses.
