The study was conducted to determine the variations of age, hair type and body condition score with sperm morphology and cations concentration in 62 Yankasa rams. The results revealed that the average abnormal morphological characteristics of ram semen were; 0.68, 0.47, 0.68, 0.47 and 0.36, respectively for detached midpiece and tail (DMT), midpiece droplet (MPD), detached head (DH), coiled and bent tail (CBT) and acrosome (ACR). Age, hair type and body condition score had significant (P<0.01) effect on sperm morphology except the effect of age on ACR and effect of BCS on MPD and ACR (P>0.05). DMT and DH were more frequent in younger rams of between 12 and 24 months of age than rams of later ages. On the other hand, the problem of MPD was more frequent on rams of 25 to 36 months of age. The CBT was observed more in rams that were between 19-24 months of age. With respect to hair type, the long-smooth haired rams had the highest DMT and DH abnormalities (1.0 x 106), while the short-smooth haired rams had the highest MPD abnormalities (0.6 x 106) while long curly hair type had the highest CBT spermatozoa (0.7x106). However, the short-rough rams showed none of the sperm morphological abnormalities. Age, hair type and body condition score also had significant (P<0.01) effect on semen cation concentrations except the effect of BCS on Na and K ions. The result of this experiment showed that age, hair type and body condition score are important factors in selecting breeding rams for optimum performance.

China is considered as one of the biggest consumers of energy in the world, creating a lot of pollution. There is a noticeable shift to renewable energy in China to solve this issue. However the geopolitical consequences of such a significant transition have received relatively little academic study. With existing literature and most recent data, this paper suggests a general framework for exploring this topic. This paper will briefly explain the energy and environment challenges faced by China and will demonstrate the most recent and significant commitments of the Chinese government to address those challenges. Then it shows the considerable progress already made by China in the energy efficiency of their economy and how China has used renewables to diversify its energy mix. Finally the paper studies the implications, opportunities and challenges, on global politics of such an energy transition. This papers shows how a fast development of renewable energy in China affects geopolitical balance with Japan, EU and US. This paper goal aim is to enrich the theoretical literature about renewable energy geopolitics with a special focus on China. This paper demonstrates that a global energy system dominated by renewable energy will be more sustainable, just and peaceful than the one only dominated by fossil fuels.

Credible disclosure and openness of information is a symbol of good corporate governance which is important in allocation of scarcely available resources. Transparency and accountability creates and sustains confidence of investors and other stakeholders in organizations and the wider society, by providing opportunities to stakeholders to receive necessary information. Organizations may have good policies on transparency and accountability but the extent to which it is successfully implemented influences service delivery. Studies have been conducted on policies and procedures on transparency and accountability in organizations, however there is inadequate empirical literature on influence of transparency and accountability as a practice on service delivery among county owned water organizations in Western Kenya. The study sought to establish the influence of transparency and accountability practice on service delivery among county owned water organizations in Western Kenya. In order to achieve the purpose, the study hypothesized that transparency and accountability practice has no influence on service delivery among county owned water organizations in Western Kenya. The study was guided by Stakeholder Theory. The study employed descriptive survey and correlational design. Data was collected from directors, managers, employees and customers of county-owned water organizations in Western Kenya. The sample size for directors, managers and customers were determined using purposive, stratified, simple random sampling technique. The study collected both qualitative and quantitative types of data using self-administered semi structured questionnaires and interview guides. The overall value of Cronbach’s reliability was high enough while Validity was checked by University experts and content validity index met the threshold. Normality test was conducted using Shapiro Wilk test. Data analysis was done using descriptive statistics of inferential statistics such as Pearson’s Product Moment Correlation Coefficient and Simple Linear Regression. Qualitative data was analysed using content analysis. Data is presented in form of tables. The values of Pearson correlation coefficients established that there existed a relationship between transparency and accountability and service delivery. The results of simple regression analysis established that transparency and accountability was statistically significant on service delivery among county owned water organizations in Western Kenya. It is hoped that the findings will benefit various stakeholders such as customers, in the water sector in Kenya, and academic researchers. The study recommended that organizations should embrace dissemination of necessary information to stakeholders in order to ensure that there is improved service delivery.

We have given at home simple solutions about problems related to heating issue of main chip, power supply problem, beep problem, hanging problem, red light problem and processor problem through this diagnostic card.

Development of eco-friendly systems and energy efficient systems has been a great concern for sustainable development. In the present research paper, we are using a two-stage evaporative cooler (TSEC) consisting of two evaporative cooling chambers. The temperature drop through TSIEC can be achieved to be about 100K or below by applying the combined concept of bootstrap air refrigeration cycle and evaporative air refrigeration cycle. In this system we are using indirect evaporative cooling of compressed air in two stages of compression followed by cooling to attain very low temperature which can be used for scientific researches and cryogenics.

Acute upper gastrointestinal bleeding (UGIB) is a common emergency and can be a serious condition that requires hospitalization, rapid evaluation and management. The usual presentation is hematemesis (vomiting of blood or coffee ground-like material) and/or melena (black, tarry stools). UGIB occurs more commonly in men and older subjects. Peptic ulcers are the most common cause of UGIB. Esophago-Gastro-Duodenoscopy (EGD) is a primary diagnostic and therapeutic modality in the setting of UGIB. This study aims to evaluate causes and outcomes of UGIB in the emergency. Material and methods: monocentric study conducted from January 2019 to January 2024. Were included all patients hospitalized by our Unit for a UGIB as : hematemesis and/or melena and/or hematochesia with severe anemia or hemodynamic instability. All patiennts had an oesophagogastroduodenoscopy (EGD) to find the cause of bleeding and for a therapeutic approach when possible. Results: A total of 737 individuals underwent UGE for UGIB during the study period. Mean age was 56,3 years and 58,7% of patients were male. Among all patients, 17.3% reported consumption of NSAIDs and 21,4% were taking anti-thrombotics. The most frequent presenting symptom was isolated melena in 37,8% followed by melena associated with hematemesis in 31,4%, isolated hematemesis in 27,4% and abundant hematochezia in 3,4%. Hemodynamic instability was seen in 24,5% of patients. Ulcers were the most common cause of bleeding seen in 36,9% : duodenal in 23% of the patients and gastric in 13,9%. 59% of those ulcers were classified Forrest III. Esophageal and fundal varices were found in 19,8% of the cases. The other causes of bleeding were : oesophagitis in 12,2% of the patients, gastritis (including gastric erosions) in 10%, gastric or duodenal neoplasm in 9,3%, vascular anomaly in 2,2% and postoperative in 1,6%. The oesogastroduodenoscopy was normal in 8% of the patients. Regarding therapeutic interventions, 41,5% had undergone therapeutic endoscopy. Conclusion: UGIB is a frequent cause of hospitalization in the emergency. EGD has a diagnostic as well as therapeutic role in UGIB .In this study endoscopy provided diagnosis in 92% of patients. We found duodenal ulcers as the most common cause of upper GI bleeding followed by gastric ulcers, and clean based ulcers were the most common type of peptic ulcers. Varices are an important cause of massive variceal bleed. NSAIDs and anti-thrombotics are important factors for UGIB.

The ventilatory failure after a programmed extubation is defined as the inability to maintain spontaneous ventilation within a period of 72 hours of surveillance. The incidence of this problem is approximately 15%, and causes related to respiratory problems include 28% of the total being the principal cause of ventilatory failure and left ventricular dysfunction is the second cause. The criteria used to determine the possibility to extubate a patient only include respiratory factors; from the cardiac point of view only contemplates the use of amines. So far there is no a reliable noninvasive marker that can predict heart failure as a cause of ventilatory failure. Considering that the increase in ventilatory mechanics defines the majority of cases of ventilatory failure after extubation, it is possible that a tissue hypoperfusion marker could discern those patients with the possibility of ventilatory failure. In situations with low tissue perfusion, the difference in carbon dioxide is seen as an increase in CO2 in the venous blood and related to a decrease in cardiac output according to Fick equation. The amount of CO2 in venous blood is dependent on blood flow. For this reason, an increase in the venous-arterial CO2 difference reflects a decrease in blood flow and tissue hypoperfusion that could be used as a predictor of failure in extubation. We propose delta CO2 as a risk marker for ventilatory failure after extubation.

Bioindicatora are living organisms which can be used to screen the health of the natural ecosystem. Plankton assesses the ecological changes taking place in freshwater environment. The assessment of water quality using plankton promotes water quality and yield. The quality of aquatic ecosystem reflects the quality and species of organisms that colonize it. In Nigeria, the freshwater ecosystem represent over 50% of the natural resources that sustain over 45% of the over 220 million population. Water bodies of the world represent over 75% of global natural resources that sustain over 60% of world population of over 6 billion, projected to reach over 9 billion by 2055. Hence, the place of water bodies cannot be underestimated in sustainable livelihood and standard of living. Their pollution due to massive anthropogenic activities are worrisome. Hence, the constant monitoring of their quality has been called by marine and other scientists. This review details the role of plankton in water quality and yield assessment.

In the modern era, social media such as Facebook can be used as a new technique of educational learning. Contemporary higher education students grew up surrounded by digital technologies and therefore have the expectation that technology should be a fundamental part of their learning process. However, technology merely offers an opportunity for these “digital native” students; how they choose to utilize this opportunity is a more complex decision as previous studies have raised concerns of distraction, abuse of use, and lack of strategic direction with usage in order to achieve meaningful learning. Consequently, the potential of introducing social media into formal learning in relation to the achievement of collaborative learning, social interaction, collective achievement and learning, student-centred learning, information sharing, and access to information through multiple resources might be short-changed if the argument against the integration of social media into learning is sustained and upheld. This paper proposes that Facebook can be establishes as a part of the students’ real-life applications for what they learn in the classroom. Furthermore, this study aims to explore how teachers can use social media as formal learning tools.
