Published: November 2023

The aim of this study was to evaluate the growth of goats and the economic value of rations by using ground corn gelatinization products with urea as slow-release urea in ration supplements. The experiment was conducted on twelve male local goats, aged 1-1.5 years with a body weight of 12.839 ± 0.496kg. The ration was prepared with a 60:40 ratio of forage to concentrate. The basal feed was made of Gamal leaves, while the concentrate consisted of soybean meal, ground corn, rice bran, coconut meal, and ground corn gelatinization product with urea. The experimental method used in this study was a 4x3 completely randomized design (CRD) with four treatments. The treatments applied were T0 (control), T1, T2, and T3. T0 was the basal feed + concentrate without ground corn gelatinization product with urea, while T1, T2, and T3 were the basal feed + concentrate with 1.5%, 2.5%, and 3.75% ground corn gelatinization product with urea, respectively. The data collected were statistically analyzed using analysis of variance and Duncan's multiple range test. The results showed that the treatment had a significant effect (P <0.05) on total dry matter consumption, ration utilization efficiency, and economic value of rations. In conclusion, the study found that the use of ground corn gelatinization products with urea is a viable option for enhancing the quality of goat rations.

With a morbidity of 600,000 cases and 375,000 lethal cases per year, cervical cancer (CC) is the second most prevalent gynecological cancer all over the world. Because of the absence of a widespread preventative campaign, CC has a significant impact in developing countries. An acceptable, efficient, and cost-effective screening technique in low-income nations is the visual inspection of the cervix with acetic acid and Lugol's iodine. By conducting a CC screening exercise in Doukoula, we hope to ignite the culture of CC screening campaigns in the Kar-Hay health district in the extreme north of Cameroon. Methods: Doukoula District Hospital hosted a one-week CC screening and treatment exercise from the 3rd of November 2021 to the 9th of November 2021. Treatments for dysplastic lesions included thermal coagulation and LEEP. To improve cervix visibility, a MobileODT colposcopic gadget was used. Results: 306 women in all agreed to take part in the study. A screening uptake of 82% was achieved, with 251 of them completing the process. 7 (2.8%) declared being HIV positive. The mean age of this study was 37.33. We had 31 cases of dysplasia (12.75%) and 1 case of cervical cancer (0.4%). Out of 251 participants, only 3 (1.2%) had undergone CC screening, and just one had received an HPV vaccination in the past. Five CIN-1 cases, aged 25 years and below, did not receive any treatment. The 11 cases of CIN 1 aged over 25 years and the 13 CIN 2 cases were eligible for thermotherapy. The two CIN-3 cases had a LEEP, and a sample was taken for pathology analysis. 20 presented themselves for treatment. The total uptake for treatment was 76.72%. Conclusion: Despite growing recognition that cervical cancer is a disease that can be prevented, relatively little is being done to increase vaccine, screening, and treatment rates. While waiting for the development of efficient national screening systems, the use of a “see and treat” screening strategy is a reasonable method of approach for the prevention of CC in low-income countries.

It arms to determine the physical and mechanical properties of particleboards from mahogany sawdust bonded by pearls bone glue or tannic powder of peel of Indian tamarind (Pithecellobium Dulce). The influence of the size of particles on the physical and mechanical properties of the particleboards is studied. Five different granulometries (raw sawdust; 2.5 < g £ 5; 1.6 < g £ 2.5 and 0.8 < g £ 1.6, and g £ 0.8) were investigated. The rate of the adhesives used were 5; 6.5; 7; 7.5; 8; 10, 12.5 and 15 percent. Physically, the density, thickness swelling (TS) and water absorption (WA) were evaluated. Mechanically, the modulus of elasticity (MOE), the modulus of rupture (MOR), the modulus of Young E, the tensile modulus of rupture (MOT) and the internal bond (IB) were determined. The results obtained showed that the granulometry has a great influence on the physical as well as the mechanical properties of the Mahogany sawdust particleboards. The pressing temperature is 160 °C. The threshold fixed by the American standard ANSI A208.1-2016 for the MOE and the MOR are widely reached. The values of the density classified the particleboards from sawdust of Mahogany wood in the categories of low and mean density. The thickness swelling and water absorption has not respectful to the American standard ANSI A208.1–2016 [1]. So, the manufactured boards can only be used in dry conditions.

The Loranthaceae are known parasites of natural forests, plantations, orchards and ornamental plants throughout the world and their rampant infestation of plants along the windward slope of mount Cameroon is a cause for concern. This research was designed to identify the species of Loranthaceae along the windward slope of mount Cameroon and identify the host range. Field assessment of the parasite and host range studies were done in a rectangular plot (200 x 50 m) laid within 16 localities each along the slope. Two Loranthaceae species, Phragmanthera capitata (Sprengel) S. Balle, and Tapinanthus apodanthus Sprague were found to parasitize a total of 38 species belonging to 18 families. Phragmanthera capitata (Sprengel) S. Balle, and Tapinanthus apodanthus Sprague were found to parasitize a variety of trees and shrubs species. Phragmanthera capitata (Sprengel) S. Balle, had the highest host range with 36 species while Tapinanthus apodanthus Sprague parasitized 27 species. Of the parasitized plants, 13 species were unique to Phragmanthera capitata while 2 species Mangifera indica and Acacia sp. were unique to Tapinanthus apodanthus. Twenty-three (23) species were common to both parasites. The Lauraceae had the highest number of individual infested species recorded, like Persea americana Mill, infested by both parasites. Euphorbiaceae and Fabaceae were the two families specious with 5 and 4 infested species respectively. Similarity indices for host species of Phragmanthera capitata (Sprengel) S. Balle, and Tapinanthus apodanthus Sprague, showed that 0 - 249 m asl and 250 - 499 m asl were greatly similar.

Published: November 2023

Science teachers face several challenges in creating and implementing inquiry-based learning in Physics education. Part of this problem can be attributed to the fact that Physics is an imaginative science, which limits the students’ readiness to grasp the concepts and demotivates them to pursue further studies related to Physics. This only suggests the need to introduce strategies that promote easy visualization and cultivate students’ interest in the subject. This study examined the effect of PhET simulation on the academic performance and motivation of Grade 10 students to learn Ohm’s Law. Specifically, it aimed to a) compare the students’ pretest and posttest scores; b) determine their level of motivation in the five motivational areas (i.e., intrinsic, self-efficacy, self-determination, grade, and career); and c) determine the relationship between students’ motivation and post-test score. Using the Physics Motivation Questionnaire II (PMQ-II), 61 students were surveyed after a 2-week lecture in Ohms’ law. A paired t-test revealed that the PhET simulation is valid for improving the performance of the students on Ohm’s Law. Among the five constructs of motivation, grade motivation and intrinsic motivation were the highest after the intervention. Lastly, it was found that the posttest scores of the students correlate positively with their motivation to learn Ohm’s Law. Based on these findings, it is recommended that teachers continue to utilize PhET simulation to its full potential by letting students manipulate and interact with the program.

Authors: Ifeyinwa Nkemdilim Obiokafor
Published: November 2023

The pervasive reliance on cybersecurity innovations by enterprise organizations for secure electronic file-sharing networks across all business transactions is critical to realizing Nigeria's sustainable diversified economy (SDE) for long-term economic growth. According to the literature, people are increasingly moving away from using cash for transactions as a result of technological advances, with only 32% of payments involving cash in the United States, 53% in the Middle East, Africa, and Nigeria, and a comparably low 58% identifying going cashless as their preferred option. Although card payments are widely preferred worldwide, Nigerians continue to be among the most likely people to keep money in their homes rather than adopting the ongoing cashless trend; the estimated percentage of cash that is kept outside of the banking system relative to the total amount of cash in circulation in the Nigerian economy is 85%. Poor organizational systems, enterprises, risks, and security threats further impede the transition from a cash-dominated economy to a cashless economy. In the age of cashless transactions, this study outlines tactics for a safe, diversified, and sustainable Nigerian economy. The conceptual framework for this study was chosen to be the security of Enterprise Information Systems (EIS). The author conducted a narrative review of previous studies and peer-reviewed articles published in the last five years, and the findings provided important insights into how to manage information security systems for organizations in a cashless economy. The findings suggest that effective adherence to security policies, control over policy enforcement, and enterprise definitions to leverage a sustainable, diverse economy can prevent or mitigate organizational security issues. The study's conclusions broaden appropriate security management procedures and preventative measures for Nigeria's transition to cashless transactions

Published: November 2023

This research is based on the importance of a security system in a room by implementing AI combined with the telegram notification system. The goal is that security information can be obtained quickly and in real-time. The methodology used is to design a hardware system consisting of input, process and output devices. The input device consists of a Logitech C270 camera mounted on 2 MG966R type servo motors so that the camera can rotate on the X and Y axes, then the results of the camera captures are processed using the Haar Cascade Classifier and Local Binary Pattern Histogram (LBPH) algorithms. Raspberry Pi 4 is used as a data processing center and push notification to telegrams in the form of images when faces are detected by a web camera. Only registered users may enter the room, by opening the door when a face is recognized. Our findings show that a room security system with an AI-based facial recognition application can be implemented, according to the planning and design results in this study. The door opening process produces an average result of 4.586 seconds, with the longest time being 4.981 seconds and the fastest time being 4.116 seconds. The door closing process produces an average result of 4.496 seconds, with the longest time being 4.966 seconds and the fastest time being 4.106 seconds. The average time of opening and closing the door is ideal and safe. From the results of the research that has been done, it can be concluded that the use of AI in this study aims to make decisions that only registered users can enter a room. In addition, the ability of the camera to move dynamically on the x and y axes is one of the system developments that did not exist before, so that the ability to take pictures besides being more accurate also becomes wider dynamic.

Published: November 2023

Excavators are often used in mining projects such as for penetrating, excavating, dredging, gouging, and crushing mineral rocks. Bucket teeth are an excavator component that is often being replaced due to failure. The most common failure mode that occurred in bucket teeth was wear on the tip or front section of it. To reduce the wear of the bucket teeth material then its hardness should be increased. As the hardness value increases, the resistance to wear increases. The bucket teeth were made of Creusabro 8000 steel and a hardening process was then carried out on the front section of the bucket teeth components by using an induction furnace. The power used in the induction furnace varies from 28, 35, 42 and 49 kW (kilowatts) and the holding time varies between 3 and 5 minutes. The heat treatment process used oil as a cooling medium. The analysis was carried out to determine the area that experienced an increase in hardness and its occurred microstructure. Microstructure examination was carried out with an optical microscope, and hardness test by using a Vickers microscopy. It can be concluded from the result of the analysis that the large area experienced an hardness increase is directly proportional to the electric current magnitude and holding time. The microstructure has changed from fine pearlite to martensite thus hardness of Bucket Teeth can be increased up to 100% of the initial hardness.

Published: November 2023

The effect of sintering temperature on the crystal structure and physical properties of the Mg0,92Zn0,05C0,03 alloy has been studied. Magnesium-based alloys are one of the alloys that have been used in industry, the health sector, and as biodegradable materials and biomaterials. The aim of this study was to determine the effect of temperature and sintering holding time on crystal size, dislocation density, microlattice strain, and yield strength, porosity and density of Mg0,92Zn0,05C0,03 alloy. The results of testing the crystal structure of the alloy Mg0,92Zn0,05C0,03 with an X-ray diffractometer showed several diffraction peaks consisting of the main phase α–Mg and a small part of the MgZn phase. Testing of Mg0,92Zn0,05C0,03 alloy after sintering with variations in temperature and 90 minutes holding time for crystal size showed that the higher the sintering temperature (425 0C to 575 0C) the crystal size value decreased significantly from 82.36 nm to 18.75 nm, and the dislocation density increased from 0.113 to 0.868 lines/mm2. For micro strain decreased from 0.015 to 0.0087. However, in the very small porosity test, the increase was from 29.8% to 31.9%. As well as for density (1.8 gr/cm3) and yield strength (274 MPa) there was no significant decrease of around 1.4%, but the synthesized Mg0,92Zn0,05C0,03 alloy fulfilled as a bone implant bio material.hhThe effect of sintering temperature on the crystal structure and physical properties of the Mg0,92Zn0,05C0,03 alloy has been studied.

Analysis of liquid rocket propellant in nitroglycerin injector reactors
Authors:   politeknik negeri malang Indonesia, maryono maryono , Rizza Muhammad Akhlis
Published: November 2023

The propulsion of the rocket is due to the thrust resulting from the combustion rate. The propellant energy can be increased by increasing the fuel pressure and temperature of the propellant. Increasing the pressure and temperature of the propellant will increase its combustion rate and the operating conditions of the rocket motor. The most effective liquid propellant used is Nitroglycerin (NG). Nitroglycerin was prepared using the glycerol nitration method with the principle of an injector-based reactor. Therefore, in this research, nitroglycerin was made using the Injector Reactor method with variations in flow rate and injection volume. The results showed that the effect of variations in flow rate and solution volume on the synthesis of nitroglycerin caused a change in solution temperature. Flow rate is closely related to the volume of solution used. The higher the temperature produced, the more heat energy will increase so that the pressure and combustion rate of the propellant increase. The most optimum results use a flow rate of 200 µm/s and a solution volume of 6 ml of glycerin, nitric acid, and sulfuric acid each with a temperature of 37.6oC.

Designing of Evaporator Length in Very Low Temperature Chest Freezer by using Environmentally Friendly Refrigerant R290
Authors:   Politeknik Negeri Bandung, Sumeru Kasni , Nugraha Ridwan , Badarudin Apip
Published: November 2023

Chest freezers generally use R600a or R134a as working fluids. When using R600a, the minimum cabin temperature is only -10oC, whereas when using R134a, it can reach -25oC. The purpose of this study is to calculate the evaporator length of a chest freezer that uses R290 as a refrigerant so that its cabin temperature can reach below 35 oC, lower than the cabin temperature of a typical chest freezer. Calculation of the evaporator pipe length is done using the forced convection heat transfer equation to calculate the heat transfer coefficient inside the evaporator pipe and natural heat transfer to calculate the heat transfer coefficient outside the evaporator pipe. Based on the calculations, the chest freezer has a compressor capacity of 200 W, an evaporator length of 3.57 m, and a diameter of 3/8 inch or 9.52 mm. The test results show that the temperature of the chest freezer cabin can reach -36oC in the 36th minute with a cooling capacity of 289 W, while the input power and COP are 198 watts and 1.46, respectively. Compared to R134a, the use of R290 is more advantageous. In addition to lower cabin temperatures, it is also much more environmentally friendly, because the GWP (global warming potential) value of R134a is much higher than that of R290. It means that the use of R290 as a working fluid in the chest freezer will significantly reduce emissions of gases that cause global warming.

Providing healthy food education for toddlers is one of the efforts in overcoming the problem of stunting. Providing education, counseling, and behavior change is included in the form of sensitive nutrition interventions, namely increasing awareness of parenting and nutrition for toddlers. The community service activity aims to increase the nutritional knowledge of mothers of toddlers on healthy and nutritious foods for toddlers and determine the relationship with the incidence of stunting. The methods used in this activity are lecturers delivering educational content directly to mothers of toddlers with the aid of visual media in the form of PowerPoint presentations. Pre and post-test questionnaires were given before and after education to measure the nutritional knowledge of mothers of toddlers. The nutritional knowledge scores obtained were statistically analyzed using Paired T-Test. The results of statistical analysis showed that there was a significant increase (p<0.05) in the mothers' knowledge scores before and after education. The service team also provided several examples of healthy foods for toddlers, especially complementary foods that are easy to make as an alternative to feeding children under five.

Exploring the Sources of Variance in Risky Decision Making with Large Language Models
Authors: Bhatia Sudeep
Published: November 2023

What are the sources of individual-level differences in decision making, and how do they depend on the domain or situation in which the decision is being made? Psychologists currently answer such questions with psychometric methods, which analyze correlations across participant ratings in survey datasets. In this paper we model the psychological mechanisms that give rise to these correlations. Our approach uses 1. Large language models (LLMs) to quantify everyday behaviors in terms of the attributes or reasons that may describe those behaviors, and 2. Decision models to map these attributes and reasons onto participant ratings. We show that LLM-based decision models can explain observed correlations between risky behaviors in terms of the reasons different behaviors elicit, and explain observed correlations between individuals in terms of the weights different individuals place on reasons, thereby providing a process-level foundation for psychometric analysis. Since LLMs provide quantitative representations for nearly any naturalistic decision, they can be used to make accurate out-of-sample predictions for hundreds of everyday behaviors, predict the reasons why people may or may not want to engage in these behaviors, and interpret these reasons in terms of intuitive psychological constructs. Our approach has important theoretical and practical implications for the study of heterogeneity in everyday decision making.

There is consistent evidence for a positive association between education and a wide range of cognitive abilities. In particular, spatial abilities have been shown to be strongly related to academic achievement. However, studying this association is complex as both education and spatial abilities are modulated by multivariate sociodemographic factors, likely to vary across countries. Most previous studies relied on small sample sizes or were restricted to a limited number of countries, thus were unable to control for these covariates. To overcome these limitations, we used a spatial navigation task embedded in a mobile video game. We quantified the wayfinding ability of 397,162 people across 38 countries and showed that on average, education level was positively associated with wayfinding ability. This difference was stronger in older participants and increased with task difficulty. However, the effect of education was different across countries, from near-zero and non-significant in India (Bayes' factor = 0.08, Hedge's g = -0.03, 95%CI = [-0.15, 0.08]), to modest and significant in Romania (Bayes' factor = 345.44, Hedge's g = 0.15, 95%CI = [0.08, 0.22]). We did not find any relationship between the education effect size of countries and economic indicators such as GDP per capita. Using the 1972 reform increasing the minimum school leaving age in the UK as a natural experiment, we used a regression discontinuity design to show that education has a causal effect on wayfinding ability.
Framing the Default: Influence of Choosing vs Rejecting Frame on Default Effects
Authors: Chandrashekar Subramanya Prasad , Fillon Adrien Alejandro
Published: November 2023

A key finding within nudging research is the 'default effect,' where individuals are inclined to stay with a default option when faced with a decision, rather than exploring alternatives (e.g., a pre-selected job opportunity among two alternatives). Similarly, the study of framing effects delves into how the presentation and context of decisions influence choices (e.g., choosing vs. rejecting a job opportunity among two alternatives). Specifically, previous literature examining 'choosing vs. rejecting' decision frames in various situations has found that these frames do not invariably complement each other, therefore individuals’ preferences vary based on the task frame. Yet, simultaneous testing of multiple nudges remains relatively unexplored in the literature. In the current study involving 1072 participants, we examined how framing and default effects can influence decision-making in hypothetical scenarios. The decision scenarios involved two different domains—work and health. We found that framing had a strong effect on decision-making in both work and health domains, whereas default setting contributed only to a limited extent in the work domain and no effect was found in the health domain, mirroring related recent research findings. We argue for a more careful design of nudge interventions when multiple overlapping nudges are used and for a contextual approach to applying behavioral science to citizens.
