Authors: Chaurasia Pankaj Kumar , Bharati Shashi Lata , Singh Sunita , Kumari Sunita
Published: March 2024

In this comparative study, direct protein determination have been done for indigenous Red lentil (Lens culinaris) and Moong pulse (Vigna radiata) (obtained from Muzaffarpur, Bihar) by UV-visible spectroscopy in three different solvents viz. double distilled water(ddH 2 O), ethyl alcohol (C 2 H 5 OH), and methyl alcohol (CH 3 OH). A few amino acids insolutions have also been predicted (not characterized) based on their peaks observed in UV-region by comparing them with the reported range of wavelengths. Protein concentrations in red lentils for ddH 2 O, C 2 H 5 OH, and CH 3 OH extracted solution were 7.480, 1.205, and 0.835mg/mL, respectively. While, in case of moong pulse, protein concentrations in ddH 2 O,C 2 H 5 OH, and CH 3 OHextractedparts were 6.415, 1.150, and 3.485 mg/mL, respectively. Inboth cases, ddH 2 O extracted part showed the highest concentration of proteins while red lentil showed higher concentration in C 2 H 5 OH followed by CH 3 OH and moong pulse showed higher concentration in CH 3 OH followed by C 2 H 5 OH. During comparison with known wavelength ranges for amino acids peaks, red lentil in ddH 2 O showed peaks for cysteine, phenylalanine, tryptophan, and tyrosine; in C 2 H 5 OH peaks were only for cysteine and traces of phenylalanine; while in CH 3 OH, peaks were for cysteine, phenylalanine, tryptophan, and tyrosine. Whereas, moong pulse in ddH 2 O showed peaks for cysteine, phenylalanine, tryptophan, and tyrosine; in C 2 H 5 OH and CH 3 OH peaks were observed only for cysteine and phenylalanine. This method concludes that local pulses are rich in protein and amino acids and aqueous solutions showed highest protein concentration in each case. This direct method of protein quantitation is effective in the determination of protein at wavelength 280 nm as well as prediction of a few amino acids based on their specific peaks in UV-region. The main purpose of this work was to perform a comparative analysis of the protein concentrations in three different solvent-extracted solutions of two indigenous pulses by the direct UV-Visible spectroscopic technique without using any chemical. It is well known that pulses are rich in 3 protein but in best of authors knowledge there is no report on this type of work for these local pulses using this direct and fast quantitation method. As alcohols are not the very suitable solvents for the protein extraction, however, this study was performed using methanol and ethanol along with ddH 2 O in order to assess the experimental results in these two alcohols also and compare them to each other.

Authors: Mubarok Atikah Fajriyah , Komalawati Komalawati , Setiadi Agus
Published: March 2024

This study analyses the volatility of beef prices in Indonesia, a strategic commodity that significantly impacts the welfare of producers and consumers. The sustained and erratic price fluctuations pose an economic risk to producers and threaten farmers' economic stability. ARCH / GARCH models were used to analyze daily beef price data from 10 July 2017 to 31 December 2023, obtained from the National Strategic Food Price Information Centre of Bank Indonesia. The GARCH (2,2) model is the most suitable for estimating the volatility of beef prices in Indonesia, with low and sustainable volatility in the long run. Factors that affect this volatility include feeder cattle and beef imports, exchange rates, livestock diseases, the COVID-19 pandemic, and government policies such as PPKM and PSBB during the new normal era. Important events such as Ramadan, Eid al-Fitr, Christmas, and New Year also influence price volatility of beef. This research aims to assist the government to design more effective market stabilization policies in the short, medium, and long term period.

Authors: Okoye Nkiruka Cecilia , Oranefofor P.C. , Agu Stephen Ikechukwu
Published: March 2024

The main motivation of this study stemmed from the dearth of empirical evidence of the effect of sustainability accounting disclosure on financial performance of Brewery firms in Nigeria and also to provide empirical proof on “governance disclosure” as one of the explanatory variables of sustainability accounting disclosure. Consequently, this study ascertained the effect of sustainability accounting disclosure on financial performance of Brewery firms in Nigeria. An ex–post facto research design approach was adopted for the study. The population of this study comprised five (5) Brewery firms quoted on the floor of the Nigeria exchange group (NGX), and Nigerian Breweries Plc was purposively used as the sample size of this study. Secondary data were carefully sourced from the financial statement/annual reports and sustainability reports from 2013 to 2022 of the Brewery firms quoted on the Nigeria exchange group (NGX). Least regression analysis by aid of E-views 10.0 software was used to test for statistical significance of the effect of sustainability accounting disclosure on financial performance of Brewery firms in Nigeria. The results showed that Economic Sustainability disclosure indexes do not significantly affect Net Profit Margin of Brewery firms in Nigeria. The findings further revealed that Environmental Sustainability disclosure indexes significantly affect Net Profit Margin of Brewery firms in Nigeria. More so, results showed that Social Sustainability disclosure indexes do not significantly affect Net Profit Margin of Brewery firms in Nigeria. Finally, the result established also that Governance Sustainability disclosure indexes do not significantly affect Net Profit Margin of Brewery firms in Nigeria, this study recommends among others; that managers of Brewers in Nigeria should improve and sustain full disclosure practices on economic, environmental, social and governance disclosures following the guidelines of the Global Reporting Index(GRI) as they are capable of exerting significant effect on financial performance of firms in Nigeria.

Authors: VIANA Bruna Carla Leite , VIANA JUNIOR Carlos José
Published: March 2024

As patologias nefrológicas, caracterizadas pela deterioração progressiva da funcionalidade renal, emergem frequentemente de etiologias multifatoriais, incluindo, mas não se limitando a, nefropatias intrínsecas, hipertensão arterial sistêmica e diabetes mellitus. Estas condições patológicas evoluem, inexoravelmente, através de um espectro clínico de cinco estágios, culminando na necessidade imperativa de intervenções de substituição renal, tais como a hemodiálise. A implementação da hemodiálise, embora vital, está intrinsecamente associada à indução de sarcopenia, uma condição decorrente da diminuição da síntese endógena de creatina. Esta molécula, alvo de extensivas investigações em diversas vertentes da medicina, tem demonstrado potencial terapêutico significativo, especialmente no que concerne à modulação de marcadores inflamatórios e atenuação da sarcopenia. Objetivo: O presente estudo tem como escopo a realização de uma revisão sistemática minuciosa, destinada a avaliar a eficácia e segurança da suplementação de creatina em indivíduos submetidos ao procedimento de hemodiálise, com o intuito precípuo de mitigar os efeitos deletérios da sarcopenia. Métodos: Adotou-se uma metodologia rigorosa de revisão sistemática, congregando estudos que elucidassem o impacto da suplementação de creatina sobre a condição clínica de pacientes dialíticos, focando, primordialmente, na sua capacidade de contrapor-se aos efeitos da sarcopenia. Resultados: A compilação e análise crítica dos dados oriundos dos estudos selecionados revelaram informações pertinentes acerca da efetividade da suplementação de creatina na redução de manifestações sarcopênicas em pacientes sujeitos à hemodiálise, além de elucidar aspectos relacionados à segurança deste protocolo terapêutico. Conclusão: Os achados desta revisão sistemática propiciam substrato científico para a formulação de estratégias terapêuticas mais robustas e eficazes, com o objetivo de incrementar a qualidade de vida dos pacientes dialíticos acometidos pela sarcopenia, representando um avanço significativo na prática clínica contemporânea.

Authors: Silva Wilney Fernando
Published: March 2024

Este capítulo tem como objetivo analisar a organização do laicato católico mediante criação do “Apostolado da Oração Sagrado Coração de Jesus”, que se tratou de uma poderosa estratégia que a Igreja Católica utilizou, nos anos 1930 a 1950, na cidade de Porteirinha, Norte de Minas Gerais, para ampliar sua influência nos espaços escolares e extraescolares. Como método de investigação, propomos a Pesquisa Bibliográfica realizada em livros, artigos, dissertações e teses, bem como a Pesquisa Documental que inclui a análise das fontes que circulavam na época, como: livros de atas de reuniões de docentes, jornais locais, leis e decretos do executivo local, documentos pontifícios, manuscritos, obras de memorialistas, álbum de fotografias, livros de atas das associações religiosas e seus manuais, livros do tombo e livros caixa paroquial. O trabalho foi dividido da seguinte forma: no primeiro momento, apresentamos a participação política da Igreja nos anos 1930 e a estruturação da cidade de Porteirinha/MG. No segundo momento, a fim de entender o projeto de formação de crianças, homens e mulheres da cidade, faremos uma análise acerca das ações do Apostolado da Oração. Ao transitar no texto, dissertaremos como o legado católico penetrou nos poros culturais da cidade por meio da associação religiosa, bem como se deu o investimento na composição maquínica do poder do Estado. Finalmente, ao levantar as fontes, podemos concluir que nesse panorama a Igreja dialogava com os grupos políticos que objetivavam o mesmo ordenamento social. Ao Apostolado da Oração, em especial, cabia coroar a ritualização da obediência, da vida familiar cristã disciplinada, da ordem social e política, da moralização dos costumes e dos sacramentos da Igreja Católica.

Authors: Pokhrel Leela Balab , Chhetri Ramesh Kumar
Published: March 2024

A positive perception of the geography subject is crucial for students' academic success and their interest in learning. The identification of students’ perceptions of subjects has been carried out in many educational curricula.  However, it is rarely studied in Bhutan. This study explores the students’ performance in middle and higher secondary school and their academic performance in Dagana Dzongkhag (district). To study the students’ perceptions of learning geography, the data were collected from key stages IV and V students using a convergent parallel mixed-methods design from four schools. A total of 282 students, comprising 181 from key stage IV and 101 from key stage V were selected from two middle secondary and two higher secondary schools. The quantitative data were obtained using a survey questionnaire, and the qualitative data were collected from four FGDs (focus group discussions). The findings revealed that the students have positive perceptions of learning geography, irrespective of their stages. There is a significant difference in students’ perception of learning geography between key stages IV and V. The students of key stage V have a comparatively positive perception compared to those in key stage IV. It is evident from this study that students’ perceptions towards the subject would also impact their academic performance. Therefore, to address the research findings, this study recommends the district education office and school management to prioritize geography education and establish proper mechanism to support it through relevant authorities. The study has also opened the way forward for future researchers to explore similar research with a larger population.

Published: March 2024

Equipping students with proficient environmental problem-solving skills is critical in the 21st century to address pressing global problems. This research explores the effectiveness of Project-Based Learning (PjBL) combined with ecological intelligence as a strategy to increase students' cognitive understanding and environmental awareness. A quasi-experimental design with a pre-test and post-test control group design was used. The participants were class XI IPS (Class XI IPS) students from SMA Negeri 1 Karangrejo (n = 5 classes). Purposive sampling resulted in an experimental class that was exposed to PjBL and a control class that followed traditional learning. Data collection was carried out through descriptive tests and observations that were validated and reliable. Two-way ANOVA analysis showed a significant positive effect (p less than 0.05) between PjBL and ecological intelligence on students' environmental problem solving abilities. Interestingly, no significant interaction effects (p greater than 0.05) were detected, indicating the potential dominance of the PjBL structured learning environment. These findings highlight the potential of PjBL as a pedagogical tool to foster environmental literacy and problem solving in geography education

Authors: Tou Nurhaeka , Endraswari Putri Mentari , Annisa Nur , Juniawan Fransiskus Panca
Published: March 2024

The toddler period is the period after birth up to the age of 59 months. During this period, the immune system in the toddler's body is not yet working optimally, so during this period the toddler is more vulnerable to attacks from various diseases. When a toddler is sick, it is not uncommon for parents to feel confused about what to do or misinterpret the symptoms experienced by the toddler. In conditions like this, the role of a doctor is very necessary. However, in reality, not all parents want to see a doctor, because of the high cost of treatment. Therefore, we need an expert system for diagnosing toddler diseases using the Certainty Factor method to support parents' ease in identifying symptoms and illnesses suffered by toddlers as early as possible. This study used 12 data on toddler illnesses with 51 symptoms. The results of this research show that from the 15 cases that were tested, the precession value was 86.66% and the recall value was 100%. Based on the results of this research, it can be concluded that this system can be used by users to diagnose illnesses in toddlers. With this system, it is hoped that parents can determine the type of disease experienced by toddlers quickly, precisely, and efficiently.

Published: March 2024

There are many types of plant, not all recognized by people. Indonesia has many varieties of plants across the country, from Sabang to Merauke. Often, we find some fruits or plants that grow in different areas called by different names. The goal of this research is to create an application that can recognize plant types from their characteristics. These characteristics can be leaves, fruit, flowers or roots. Current research focuses on distinguishing several types of plants including their varieties using leaf images. It is hoped that apart from being able to determine the mango plant, we can also determine the type of mango, such as manalagi, harum manis, as well as guava and orange. To be able to recognize these types of plants, an object recognition algorithm based on CNN (Convolutional Neural Network) will be used.

Crinum zeylanicum bulb is a traditional folk’s herb that has been widely accepted by most rural communities for the treatment of bone fracture and other illnesses. This study assessed the influences of C. zeylanicum bulb extracts on blood pictures of rabbits through close tibia osteotomy over the period of three months. Assay of the whole blood collected through cardiac puncture was done by determining the Packed Cell Volume (PCV%) (Micro-hematocrit method), White Blood Cell (WBC%), Red Blood Cell (RBC%) (Hemo- cytometer method), Haemoglobin (HB g/dl) (Cyanomoglobin method), Neutrophil (N%), Lymphocyte (L%), Monocyte (M %), Eosinophil (E%), and Basophil (B %) (Thin smear and Leishman’s Methods). The Mean Cell Volume (MCV%), Mean Corpuscular Hemoglobin (MCH %), and MCH-Concentration (MCHC %) were calculated according to standard methods. There was significant difference (p<0.05) recorded for MCV, MCH, N and L for treated-groups as compared with WBC, MCV and N for control group while the resultant increase of WBC by ethyl acetate extract (EAE) treated group than water extract (WE) and control groups was an indication that the plant has influence on the blood constituents. M, B and E were not dictated during the pre- and post-examinations. Hence, the use of C. zeylanicum can be monitored, modified, and/or regulated for medicinal uses as the characterization of the chemical components of the plant could be a better focus for further investigation.

The conventional cassava peeling methods are inefficient, time-consuming, and labor-intensive This study aimed to create an enhanced cassava peeling machine with minimal flesh loss. The machine design includes components like a hopper, shafts, bearings, an electric motor, and a v belt connected to a pulley that drives the brush-equipped shaft. This locally sourced and fabricated machine, designed for 50kg of cassava tubers, was tested at operational speeds of 380, 420, and 460 rpm and retention times of 4, 6, and 8 minutes, optimizing the effects of machine speeds and peeling times on peeling efficiency using I-optimal Response Surface Experimental Design with a mean separation at P<0.05. Results pertaining to tuber properties, such as angle of repose, peel thickness, moisture content, peel penetration force, bulk density, and coefficient of friction, were utilized in the machine's design. The machine achieved maximum peeling efficiency of 74% at a speed of 380m/s when operated for 6 minutes. At this optimal efficiency, the machine reached an optimal throughput capacity of 171.4kg/h, with a 21% flesh loss, a peeling weight proportion of 25.8%, and minimal tuber damage (3.3%). The desirability, which signifies the extent to which these optimal values align with the optimization goal, was 0.83 (83%). In essence, this machine significantly advances cassava peeling mechanization.

The primary objective of this research was to emphasize barriers of mining and minerals in Somaliland. A questionnaire was conducted in three mining sites in Marodijex, Awdal and Sanaag regions in Somaliland. The mineral potential of Somaliland has not been thoroughly explored or investigated. Since colonial and post- independence times, the country has remained one of the last frontiers, offering chances and surprises to those that go into it. Now, there is an almost insatiable appetite for commodities, particularly mineral resources. As demand and prices grow and producing resources diminish, the global commodity business is looking for new frontiers to meet demand. Somaliland is a newly explored frontier area that is ready to divulge its secrets of oil, gas, uranium, platinum, rare earth metals, gold, copper, iron, manganese, tin, and gemstones. Mining and Minerals has a key role in Pillar One (economic development), which envisions a nation whose citizens enjoy sustained economic growth and reduced poverty levels. Somaliland is believed to contain a huge hydrocarbon resource and vast coal resources, estimated at 6 billion tons occur near Berbera (Ali, 2009). From 2020 to 2022. Somaliland mining and mineral resource sector has been hampered by several challenges including the weak regulatory framework: Somaliland mining and mineral sector face weak enforcement of legal frameworks and policies in the mining and mineral sector. Improve the regulatory environment. The Ministry of Energy and Minerals should review and update its mining laws and regulations to make them more attractive to foreign investors. This could include streamlining the permitting process, reducing taxes and royalties, and providing other incentives to exploration companies.

Published: March 2024

A technically and financially viable solution to the numerous issues associated with fuel scarcity and high cost is biodiesel. Algae biofuels represent a highly promising alternative approach to energy generation. Microalgae have been proposed as a viable alternative for fuel production due to high oil content in their cells, making them suited for development as a material source for biodiesel manufacturing. This study used dry green algae mass (Chlorophyceae) that was grounded into a smooth powder which was obtained from Delta state. A total of 100g of powder were measured. Algae oil extraction was done using lipid extraction. Additionally, acid esterification was the first step in the characterization of biodiesel. Using a standard solution of 1.0M NaOH solution, the acid value of the reaction mixture was measured using a standard acid base titration method. The results showed that the acid value was 0.280%, the iodine value was 128.592 mg/l, the specific gravity was 0.8103, the density was 0.8099 g/ml, the refractive index was read off as 1.41, the cloud points were -50C, the smokes were 2440C, and the flashes were likewise 288oC. Using USA-based Buck Scientific M530, the analysis method employed was FTIR, and FTIR spectra were co- added at 32 scans with a resolution of 4 cm-1 . The spectra were collected at frequency areas of 4,000 – 600 cm-1 . Transmitter values representing FTIR spectra were shown. Trans esterification is the technique used to turn algae oil into biodiesel. This was carried out in a round- bottom flask with a magnetic stirrer and condenser using catalyst that was supplied (three percent weight of the oil). Curves that are analytical were created. The determination of the diglycerides and triglycerides was made possible by the analytical curves from diolein and triolein. After the product was dried at 800C in a vacuum evaporator, a clear and pure biodiesel was obtained.
