Many bacteria have demonstrated the potentials of producing cellulases in copious amount. Bacteria of the genus Bacillus can utilize cheap lignocellulosic biomass to produce many bioproducts; like cellulases. One of the drawbacks in utilizing bacteria for the industrial production of cellulases is the high cost of recovering the enzyme from a submerged fermenting medium. This study seeks to produce cellulase from rice husk in a submerged fermentation. Species of Bacillus were isolated from cellulosic dumpsites, characterized and screened qualitatively for cellulase production on Carboxymethylcellulose (CMC) agar plates. The organisms were grown on mineral salt basal medium (NaNO3- 2g, K2HPO4-1g, MgSO4-0.5g, KCl-0.5g, CMC-2g, peptone-0.2g and agar- 8.5g), incubated at 40oC. The optimum conditions for the production of cellulase was found to be 60oC, at pH of 5.5 and substrate concentration of 1.0% (w/v). The crude enzyme was subjected to activated charcoal purification and the cellulase showed a 2.5 (with B. megaterium) and 1.4-fold purification (with B. cereus) in one -step purification with (3% w/v) activated charcoal, at temperature of 50 ℃ and pH (6.0) and contact time (3hrs). The result of SDS-PAGE analysis of purified cellulase using silver staining techniques showed four major bands corresponding to molecular weights of 30, 42, 55 and 70 kDa. The use of Bacillus sp. in downstream processing of lignocellulosic biomass pretreatment and activated charcoal in cellulose purification offers a huge opportunity for cutting cost. This method of enzyme purification is inexpensive, rapid, and simple which could facilitate downstream processing of industrial enzymes.

Published: February 2025

The undergraduate nursing students of SMCB in their second and third year are trained and motivated to respond with competence and compassion to the health needs of residents in underserved communities. By conducting health education, environmental cleanliness campaign, supervised immunization, deworming, rehabilitation and the like, they can elevate the health status of the communities for the better.

Community Health Nursing provides learning in the form of tasks that involve the assessment of community health needs, identification of health problems, planning of activities and evaluating the effectiveness of the plans formulated in response to the identified problems. They also implement solutions and monitor the progress of their health plans.

Community nursing exposure within the supervision of competent clinical instructors facilitates an increasingly important experience for undergraduate nursing students. Therefore, nursing education providers and health services must ensure that student nurses are exposed to high quality community that provide suitable learning experiences for them to acquire the skills, knowledge and attitudes required for optimum health services in the future

Published: February 2025

The paper examines the comparative impact of Formal (Basic Education) and Informal Education on rural development in Odukpani Local Government Area of Cross River State, Nigeria. It is argued that Basic Education will not translate into an engine of growth and rural development, except it is tailored and adapted to meet the needs of specific rural communities. There is therefore need for Basic Education programs by the Government, to be tailored to meet the needs of different rural communities, otherwise it will have an almost zero impact on development. The specific objectives were to examine the impact of access to Basic (formal) Education opportunity on rural development: and also, to find out the impact of acquisition of Non - formal Education through life skill acquisition on rural development in terms of human capital development and youth employment. Human capital development theory and structural model constituted the theoretical framework. Three hypotheses were formulated to guide the study and a well-structured questionnaire was used to obtain quantitative data from 400 respondents, using a multi-stage sampling procedure. The field data were analyzed using one-way Analysis of Variance ANOVA technique. On hypothesis one; the result revealed that the calculated F-value of 50.149* is higher than the critical F-value of 2.10 at 0.05 level of significance with 399 degrees of freedom, for hypothesis two, the result showed the calculated F-value of 63.424* is higher than the critical F-value of 2.01 at 0.05 level of significance with 399 degrees of freedom, under hypothesis three, the result revealed the calculated F-value of 10.849* is higher than the critical F-value of 1.52 at 0.05 level of significance with 399 degrees of freedom; which implies that Basic-Nine Education, Acquisition of skills and Formal Basic-Nine Education has significant influence on employment opportunities/income generation, and acquisition of life skills in Odukpani Local Government Area of Cross River State and therefore, very strategic for the development of rural areas. It was recommended, among others, that an accessible educational system in a conducive school environment with skill acquisition programmes should be promoted in order to enhance human capital development, labour productivity and gainful employment opportunities in rural areas.

The diagnosis of diabetic ketoacidosis complicated by acute pyelonephritis on a single ectopic kidney was confirmed through biological, radiological, and bacteriological assessments, with Escherichia coli identified as the causal pathogen. Insulin therapy and targeted antibiotic treatment led to a favorable outcome. This case highlights the importance of early diagnosis and prompt management of urinary tract infections in diabetic patients with renal anatomical anomalies.
Family center maternity care education for pregnant women through the approachin efforts to prevent stunting: a quasi-experimental
Authors: Desiyanti Irne Wida , Ardiningtyas Lisa
Published: February 2025

Background: Stunting in children is a health problem that has a great influence on their physical and mental development. In Indonesia, one of the causes of high stunting rates is the low health awareness of pregnant women, especially those who marry at a young age. Family factors have a significant influence on the success of stunting prevention, but family-based approaches are still rarely applied in pregnant women's health education programs.Purpose: This study aims to develop and evaluate the effectiveness of the Family Centered Maternity Care (FCMC)-based education approach in increasing knowledge and efforts to prevent stunting in pregnant women in Kolongan, North Minahasa.Methods: This study uses a quasi-experimental design with a pretest-posttest approach. The research sample consisted of 20 pregnant women who met the inclusion criteria. Data were collected through stunting knowledge questionnaires and stunting prevention efforts questionnaires, which were measured before and after FCMC interventions. Data analysis was carried out using the Wilcoxon test with a significance value of p<0.05.Results: The results of the study showed a significant increase in the level of knowledge and stunting prevention efforts among pregnant women after being given FCMC-based educational interventions. Before the intervention, only 25% of participants had high knowledge about stunting, but after that it increased to 75%. Stunting prevention efforts have also increased from 40% to 80%. The Wilcoxon test showed that this change was statistically significant (p = 0.033).Conclusion: The FCMC-based education approach has proven to be effective in increasing knowledge and efforts to prevent stunting in pregnant women. This education can be a reliable method in increasing awareness and preventive measures of pregnant women against the risk of stunting in their children.
Maluku's Dominance of Small Islands, Its Challenges, and the Role of Geography Graduates from Pattimura University in Providing Solutions
Authors: Salakory Melianus
Published: February 2025

The management of small islands in border areas, especially those bordering neighboring countries, is carried out to maintain the integrity of the Republic of Indonesia, safeguard national defense and security, improve the welfare of local communities, and develop business opportunities through bilateral cooperation. Another urgent consideration is the complex biogeophysical characteristics of small islands. As mentioned by Agus Dermawan in his presentation, these biogeophysical characteristics include: a) Being separated from the mainland, making them insular; b) Lacking a hinterland and being close to the coast; c) Unable to influence marine hydroclimate; d) Having small catchment areas; e) Limited freshwater sources, catchment areas, and food crops; f) The existence of small islands is influenced by coral reef ecosystems, mangrove forests, and seagrass beds; g) They are highly vulnerable to climate change, both natural and human-induced.
Addressing the challenges of coastal areas and small islands from a geographical approach involves the availability of fast, accurate, and objective data. Data is crucial in determining the direction and strategy of policies in the planning, implementation, and evaluation of comprehensive development, particularly for small islands. To meet these needs, the Geography Education Program at Pattimura University and its graduates, including stakeholders, can prioritize several career and policy fields in the era of Industry 4.0, digital transformation, and Society 5.0. These fields include: 1. Satellite imagery and remote sensing analysis; 2. Map production: remote sensing results and satellite image processing; 3. Urban spatial planning analysts, planners, and surveyors; 4. Transportation sector analysts and workers; 5. Edupreneurship; 6. Environmental management; 7. Private sector roles; 8. Disaster management; 9. Tour guides; 10. Environmental destination journalism
Characteristics of Inceptisol Soil in Latuhalat Village, Ambon City
Authors: Riry Roberth Berthy
Published: February 2025

Soil formation is the result of interactions between various processes, including geomorphological and pedological processes, where the soil body must be seen as a dynamic medium. Soil development is determined by soil formation factors, namely climate, topography, organisms, parent material, and time. In the process of soil formation, soil formation factors interact in the form of physical, chemical, and biological processes. The physical properties of the soil consist of soil color, soil texture, soil structure, soil consistency, soil pores, aggregates, coarse materials, mineral modules, and root conditions. The chemical properties of the soil include Base Saturation (BS), Cation Exchange Capacity (CEC), pH, Organic Carbon, and CaCO3 content. Meanwhile, the biological aspect of the soil consists of organism activities within the soil. The purpose of this study is: 1) to classify soil properties or group soils into specific classes based on their similar characteristics and features, including physical, chemical, and biological properties in the field; 2) to determine the soil type names based on the Technical Guidelines for National Soil Classification (BP3KP, 2014) and Soil Taxonomy Classification (USDA 2015) criteria. The method used is a survey method with a transect approach pattern and observation of pit profile types. The research results indicate that the soil type formed in the research location according to the criteria of the Technical Guidelines for National Soil Classification (BP3KP, 2014) is the Kambisol soil type. Approaching the Soil Taxonomy Classification (USDA 2015), this soil is included in the Inceptisol order, Tropept suborder, and Dystropept Great Group.
La evolución jurisprudencial del derecho a la salud en México y el rol de los precedentes del poder judicial de la Federación como una solución a la indeterminación de su contenido esencial
Authors: González del Valle Iván
Published: February 2025

Una de las problemáticas que acompañan a los derechos económicos, sociales y culturales en su desarrollo y aplicación, es la indeterminación de su contenido esencial en los textos constitucionales. En este supuesto normativo se ubica el derecho a la salud en México. Su formulación lingüística en nuestro orden constitucional está expuesta de forma general, lo cual produce un problema de vaguedad al momento de hacerlo exigible ante las instituciones encargadas de protegerlo. Este texto plantea la necesidad de la especificación y comprensión del núcleo esencial que configura el derecho a la salud. Esta problemática de la textura abierta del derecho a la salud se ha ido solventando gradualmente mediante la formulación y adopción de precedentes por parte del Poder Judicial de la Federación. La evolución del derecho a la salud y de su contenido se observa en las sentencias en materia de atención médica, de protección contra riesgos sanitarios y de acciones de salud pública, que en su conjunto reflejan una serie de líneas jurisprudenciales del derecho a la salud en México.
Los derechos sociales en la Constitución española: sobre la importancia de la letra de la ley cuando su espíritu es indeciso
Authors: González Ordovás María José
Published: February 2025

Bien sea por falta de rigor, bien como respuesta a una actitud dubitativa por parte del constituyente, lo que parece cierto es que la Constitución habría establecido un sistema de equilibrios. Un sistema que, en virtud de lo que se desprende de la legislación y la jurisprudencia posterior, no debe ser interpretado únicamente a la luz de la declaración de Estado social de Derecho, sino que en igual consideración han de tenerse las detalladas disposiciones del articulado. Un sistema de equilibrios que, se diría, trata de hallar un punto intermedio entre los dos paradigmas que parece acoger: el liberal y el social. Paradigmas que no sólo se observan en la solidez de las garantías conferidas a los derechos civiles y políticos frente a la debilidad de los sociales, sino que también se advierten en el bloque de constitucionalidad y en un importante sector de la doctrina.

To develop scientific and practical approaches to the formation of the concept of effective use of the oilseeds feeds obtained from the processing of seeds at domestic processing enterprises in feeding farm animals and poultry. Methods. Laboratory, technological, zootechnical and statistical. Results. The state of production and processing of the main oilseeds – sunflower, soybean and rapeseed in Ukraine is analyzed. There is a steady tendency to increase both their production and processing. The high feeding value of the cake obtained from the processing of domestic varieties of the main oilseeds was noted. Advantages and disadvantages of sunflower, soybean and rapeseed meal as feed ingredients of concentrated feeds are determined. Effective methods of processing sunflower, soybean and rapeseed feeds before use have been determined. Recommended levels of introduction of sunflower, soybean and rapeseed meal into rations of animals and poultry are given. Conclusions. Scientific and practical approaches to the formation of the concept of effective production and use of secondary products for processing oilseeds have been developed, which include the analysis and determination of optimal methods for processing oilseeds, methods for improving feed produced from them and methods for their use in feeding farm animals and poultry. At the same time, modern effective methods of processing oilseeds into oil and meal and cake are analyzed and determined. The most optimal ways of preparing feeds from oilseeds for feeding animals have been analyzed and determined. Norms of introduction of rapeseed, sunflower and soybean cake and meal into rations of animals and poultry are generalized.

Purpose. To study the influence of pre-sowing seed treatment and the rates of mineral fertilizers applied to the main fertilizer and to investigate the action and interaction of these factors on the formation of the structure and individual productivity of chickpea plants. Methods. System analysis, trial sheaf method, mathematical and statistical method. Results. It was noted that the use of microbial preparations based on nitrogen-fixing and phosphorus-mobilizing bacteria and mycorrhizal fungi for seed treatment increased plant mass by 6.0-94.0%, the number of beans – by 4.8-72.5%, the number of seeds – by 5.1-95.0%, the mass of seeds – by 8.3-100%, and the mass of 1000 seeds – by 3.2-24.7%. The introduction of phosphorus-potassium fertilizers into the main fertilizer at a rate of 30-60 kg of dry matter/ha also contributed to the increase in the above indicators, however, the introduction of “starting” and average rates of nitrogen fertilizers against the background of phosphorus-potassium fertilizers was more effective and had a positive effect on the indicators of individual productivity of chickpea plants, increasing the plant mass by 33.0-62.0%, the number of beans – by 29.7-42.7%, the number of seeds – by 36.6-52.7%, the mass of seeds – by 60.0-66.5%, the mass of 1000 seeds – by 17.1-17.5%. Conclusions. On average over the years of research (2023-2024), it was noted that the highest indicators of the structure and individual productivity of chickpea plants of the Triumf variety (plant weight – 19.4 g, number of beans – 64.5 pcs./plant, number of seeds – 65.5 pcs./plant, seed weight – 17.90 g/plant and weight of 1000 seeds – 282.4 g) were formed on the ground of the pre-sowing seed treatment with Bioinoculant, 2.5 l/t, + Organic balance mono phosphorus, 1.5 l/t, + Mycofriend, 1.5 l/t, and the application of mineral fertilizers together with the main fertilizer in the rate N60P60K60. In addition, in this variant, 3.2 branches were formed in chickpea plants, which is 52% more than in the control, and 52.6% of the fruiting zone.

Many dataset resulted by participant rating for word norms also concreteness ratio areavailable. However infrequent word and none words concreteness rank is rare. Here we usedLancaster sensory motor words’ norms , to predict word concreteness ratios of Brysbaerdataset. After removing missing values and collinear variables, we employed a SW-MLR forchoosing optimum number of norms to make a prediction MLR model. Finally we validate ourmodel using 10-fold cross-validation. The final model could predict concreteness by RMSE0.7267and R-square 0.5.
Occurrence of tetraester and mixed ether/ester-bound iso-diabolic acid membrane-spanning lipids in mineral soils
Authors: Peterse Francien , Nierop Klaas , Bale Nicole , Chen Chan-Mao , Feakins Sarah
Published: February 2025

Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are a suite of membrane lipids that are widely used as empirical proxies for past temperature and pH. Although the stereochemistry of their glycerol moiety suggests that they are produced by bacteria, the exact producers and the biosynthetic pathway of brGDGTs remain unclear. Here we report the occurrence of tetraester and mixed ester/ether membrane-spanning lipids with a backbone consisting of iso-diabolic acid (iso-DA) containing up to two additional methyl groups in mineral soils from Nepal and Rwanda. These compounds are presumed intermediate products during brGDGT synthesis but had not been detected in cultures or the environment before. Interestingly, while acid hydrolysis of the polar fraction releases iso-DA in the soil from Nepal, monoalkyl glycerol ethers with iso-C15 and iso-C17 chains are released in the soil from Rwanda. These results support both current hypotheses that brGDGT synthesis can occur via tail-to-tail condensation of two iso-C15 fatty acids to form iso-DA, as well as through the reduction of diesters to diethers and subsequent carbon-carbon linking as shown to occur during the synthesis of archaeal GDGTs.
