Cassava pulp is a by-product from the starch industry which was used as cheap alternative livestock feed. However, it has a limitation of low protein and high fibre to use in monogastric animals. Nutrient improvement of cassava pulp usually employs the use of inorganic nitrogen fertilizer. Here we demonstrated the use of chicken manure as an organic nitrogen source in compensation for the inorganic nitrogen. This research aimed to investigate the efficacy of cassava pulp fermented by dried chicken manure with yeast (CPCM) in a maize-soybean-based diets of pigs on nutrients digestibility, haematological parameters, and growth performance of barrow pigs as alternative energy feed. The results showed that the CPCM had crude protein increase from 1.99% of the plain cassava pulp to 8.54% (p < 0.05), while the crude fibre of CPCM decreased from 15.63 to 13.85%. Investigation of the diets containing CPCM as a replacement of maize at 4 levels (0%, 5%, 10%, and 15%) in twenty-four castrated male pigs (57.13 ± 3.29 kgs initial bodyweight) revealed that the control diet (0%CPCM) had the greatest digestibility percentages in all categories including dry matter, crude protein, crude fibre, gross energy, and total phosphorus (p < 0.05). Among CPCM replacement diets, the 15%CPCM generally verified a greater digestibility. The results of the feeding trial showed that there was no significant difference (p > 0.05) in feed intake, weight gain, feed conversion ratio, and haematological parameters among the four treatment diets. The haematological results showed that all parameters fall under the normal ranges of haematological pigs’ references. In conclusion, the results confirmed that CPCM can be used in the replacement of up to 15% in maize-soybean pig diets without any harmful effects.

This study was conducted to determine the growth of sugarcane (Saccharum officinarum) as affected by fermented bamboo shoot application in terms of plant height, number and diameter of nodes, number of leaves, and average number of tillers. Study results would help farmers to find an alternative source in growth promotant hormone that could find in fermented bamboo shoot (FBS) that is locally available compared to synthetic cytokinin. There were four treatments used: t1- 2 ml synthetic cytokinin/L of water (control); t2- 2 ml of FBS/L of water; t3- 7 ml of FBS/L of water, t4- 12 ml of FBS/L of water. These treatments were arranged in Completely Randomized Design (CRD) and were replicated four times. The Analysis of Variance (ANOVA) was used as a statistical tool of the study and comparison among means using Honest Tukeys Significant difference at 5% level of significance. Sugarcane plants applied with 7 ml bamboo shoot concoctions has highest mean in plant height and number of leaves which is significantly higher than synthetic cytokinin and 2 ml concoction. On the other hand, application of 12 ml concoction got the highest mean in number of nodes and nodes diameter which is statistically higher than synthetic cytokinin and 2 ml concoction but comparable to 7 ml concoction. Based on results, FBS is better source of cytokinin and could be an alternative of using synthetic cytokinin. Results also revealed that using 7 ml and 12 ml concoctions performs better in all agronomic parameters. It is recommended to use FBS as a replacement of using the synthetic cytokinin at the levels of 7 ml and 12 ml concoctions per litre of water. Further study on the effect of FBS must be conducted to determine significance in tiller production of sugarcane. Further research study for the FBS to be analyzed for cytokinin content and will be used as fertilizer to other crops and vegetables are recommended to truly validate the results.

Studying the levels of the anti-spike protein receptor-binding domain (S-RBD) antibodies as well as the vaccine safety is very important to evaluate the protection level against the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) infection and to motivate individuals to receive the vaccine. In this study, we evaluate the effect of the mRNA BNT162b2 vaccine using the EUROIMMUN anti-SARS-CoV-2 ELISA (IgG) for the measurement. We detected the IgG class antibodies to SARS-CoV-2 in the human serum, or plasma, of 217 eligible participants aged >18 years, recruited between March and June 2021. These participants were divided into 2 groups: the first group consisted of 149 participants without prior infection, while the second group included 68 participants who had recovered from symptomatic and asymptomatic COVID-19 infections. All the adverse effects were minor local or systematic reactions such as local pain, asthenia, body ache, muscle pain and headache. The level of the adverse effects increased following the second vaccine dose. The adverse effects were higher in participants with previous symptomatic SARS-CoV2 infection (p=0.020). This was due to the presence of anti-S-RBD IgG levels before the vaccination. Moreover, the adverse effects were higher in females than males after the first dose (p=0.025) and the second dose (p=0.01). As for the anti-S-RBD IgG levels, they were all positive at the end of the second dose. The anti-S-RBD IgG levels 21 days after the vaccination dose were higher than the pre-vaccination levels (p=0.000) and they were higher in previously infected participants before getting the first dose (p=0.000). Our results show a good antibody response at the end of the two mRNA BNT162b2 vaccine doses in both previously infected and not infected participants. Moreover, our study highlighted the minor adverse effects reported following each dose.

American superhero-themed films can represent good characteristics and they could be a good way of developing one’s characteristics. By utilizing American animation, superhero and fantasy films as the main data such as Fantastic 4 (2005), Fantastic 4: Rise of Silver Surfer (2007), Frozen (2013), Black Panther (2018), Frozen II (2019), and Aladdin (2019), this qualitative research focuses on the significance of character development and the representations of good characteristics depicted in the films which can be used as a tool for character education. The process of analysis involved the use of Stuart Hall’s representation theory. The results of study suggested that character is something that is essential to develop, especially in teenagers and it is not only about having a good attitude, but it also involves living a good life. In addition, this study showed that at least five good characteristics such as caring, tolerance, politeness, solidarity and kindness frequently appeared in the observed films which can be used as media for teaching about characters at schools or informal educational institutions.

The sample size for the study was 100 senior secondary school 2 students drawn from intact class of a public school through multi stage sampling technique. Two instruments were used for the collection of data, English Achievement Test (EAT) and Study Habits Counselling Questionnaire (SHCQ). The reliability of the research instruments was established using Lemma co-efficient Alpha. Data was collected and analyzed using mean and standard deviation to answer research questions and Analysis of Covariance (ANCOVA) to test the hypotheses. Findings revealed that study habits counselling has significant effect on the academic achievement of secondary school students in English. Study habits counselling has no statistical significant difference in the mean score of male and female students. The study concludes that study habits counselling has effect on the academic achievement of students in English, however, there is no significant difference between male and female. Thus, group guidance should be organized in schools to create awareness on effective study habits. A functional school library should be mounted. Parents and guardians should encourage their children to set up schedules for study. Qualified English teachers should be employed in all secondary schools. Guidance counsellors should include study habits counselling as part of new students’ orientation to facilitate effective study habits among new students.

A data center can be a single structure that contains computer systems or servers, as well as major elements including such storage and network communication systems, or a cluster of buildings that contain movable systems and related components (such as storage and telecommunications systems). All of the business area units’ key operations are run on portable servers in the data center. Several environmental and security hazards can be addressed, and continuous services can be supplied to users, thanks to the data center’s limitless observing conditions. Backup power, environmental management, and redundant data transfer connections are all included. The data center’s security and privacy are critical in this instance. It is critical to avoid time periods in the data centre. Furthermore, as public awareness of environmental issues grows, data center energy consumption has risen to the top of the safety management priority list. Failures in the temperature and humidity functions will be significant. It is critical to pay strict attention to the data center’s security at all times. Manual data center monitoring, on the other hand, is becoming increasingly time-consuming. Units in the technical field are currently emerging at a rapid pace. The data center is under the most strain in this instance. A good detector network, on the other hand, is critical to the advancement of Business 4.0 technology. As a result, we like to utilize a good network of detectors for data center observation protection and privacy. The Internet of Things is frequently utilized for data center observation, as well as a good wireless detector network. A wireless detector system is employed in this paper to track the effectiveness of adjustments in real time.

In time of pandemic, synchronous and asynchronous learning occurred as a form of distance learning implemented by the Commission on Higher Education and the Department of Education. This research entitled “Academic Dishonesty Cheating in Synchronous and Asynchronous Classes: A Proctored Examination Intervention” was conducted to identify the self-report and types of assessment stated by the respondents. It also determined the effectiveness of proctored synchronous and asynchronous examination in preventing the cheating practices of students. The researchers used a quantitative research design and three adapted questionnaires with 40 participants. The results generated from the questionnaires were analyzed using frequency, percentage, and Mann-Whitney U test. The results obtained the following: most students cheated on assignments, exams, or quizzes; the primary reasons for student dishonesty were stress and worry essentially, and homework was the kind of evaluation that enabled pupils to cheat. Proctored exams provide similar results regardless of whether the exams were conducted asynchronously or synchronously. The following findings on the impact of proctored synchronous and asynchronous exams on students revealed that: most students will be less likely to cheat in a proctored examination. Most of the students believed that these proctored examinations would be a good solution in monitoring remote learning. Therefore, proctored synchronous and asynchronous examinations prevent the academic dishonesty or cheating practices of students.
