Improving the lives of rural Indians through social innovation
Authors: Rana Usha
Published: April 2024

India is a country of villages, and a significant proportion of the population lives in the rural area. There are several fundamental challenges in the Indian villages. There is a requirement for a holistic approach to participatory development. This study addresses important facets of the interconnected problems that Indian rural society has experienced in recent decades, highlighting the dysfunctional relationships between an innovation policy that is grounded on an economically and technologically oriented, one-sided understanding of innovation. There are two aspects, first, possibilities within the village or contributions from the local community, and second the state's role in innovation. The social capital, use of local resources, and participation of stakeholders can be seen as a base for the sustainable development of the village. The study recommends the state enable rural areas in the affordable agriculture system and other small occupations, information and communication technology (ICT), communication, vocational skills courses, self-help groups, and microfinance.

The psychological impact of students' online learning performance during Covid-19
Authors: Fehaima Amaria
Published: April 2024

In the period of the COVID-19 pandemic crisis, e-learning became a necessary feature in all educational establishments such as schools, colleges, and universities. Teachers and students were required to adapt to the online learning method to ensure learning was carried out as usual, even though they had difficulties in various ways. Some of them faced depression and anxiety. This paper reviews the psychological impact of students’ online learning during COVID-19 in Algeria. Past studies determined students were affected psychologically by online learning during COVID-19 and showed symptoms of depression and anxiety. Nevertheless, many studies presented opposite results. This review recommends that the government sector take the lead in assisting students who have limited access to technology and the internet, which are prerequisites for participating in online courses. It also suggests that the government sector increases student engagement in online learning.

A new method of estimation of moduli of initial Taylor coefficients on the class of bounded non-vanishing functions
Authors: Stupin Denis L.
Published: April 2024

The task of obtaining the sharp estimate of the modulus of the n-th Taylor coefficient on the class B of bounded non-vanishing functions has been reduced to the problem of estimating a functional over the class of normalized bounded functions, which in turn has been reduced to the problem of finding the constrained maximum of a non-negative objective function of 2n-3 real arguments with constraints of the inequality type, that allows us to apply the standard numerical methods of finding constrained extrema.

Analytical expressions of the first six objective functions have been obtained and their Lipschitz continuity has been proved. Based on the Lipschitz continuity of the objective function with number n, a method for the sharp estimating of the modulus of the n-th Taylor coefficient on the class B is rigorously proven. An algorithm of finding the global constrained maximum of the objective function is being discussed. The first step of this algorithm involves a brute-force search with a relatively large step. The second step of the algorithm uses a method for finding a local maximum with the initial points obtained at the previous step.

The results of the numerical calculations are presented graphically and confirm the Krzyz conjecture for n=1,…,6. Based on these calculations, as well as on so-called asymptotic estimates, a sharp estimate of the moduli of the first six Taylor coefficients on the class B is derived. The obtained results are compared with previously known estimates of the moduli of initial Taylor coefficients on the class B and its subclasses B_t, t≥0. The extremals for B_t subclasses are discussed and the Krzyz hypothesis is updated for B_t subclasses. A brief historical overview of research of the estimations of moduli of initial Taylor coefficients on the class B is provided.
CEMÂLÎ DİVAN'INDA MİTOLOJİK VE EFSANEVİ ŞAHSİYETLER
Authors: Doğan Emine Feyza
Published: April 2024

Klâsik Türk edebiyatında mitolojik ve efsanevî şahsiyetler; daha çok memduhu övmek, dünyanın geçiciliğini anlatmak, kahramanlıkları çeşitli imgelerle ortaya koymak, aşk hikâyelerini ölümsüz kılmak gibi konular ekseninde ele alınmıştır. Klâsik Türk edebiyatının ana kaynaklarından biri olması bakımından mitoloji, şairlerin kullandıkları imaj ve sembol dünyasını genişletmiş, mazmunları çeşitlendirmiş, anlamı kuvvetlendirmiş ve anlatımı zenginleştirmiştir. On beşinci yüzyıl şairlerinden olan Cemâlî, divanında mitolojik ve efsanevî şahsiyetlere yer verirken, diğer şairler gibi divan edebiyatı geleneğine bağlı kalarak, Şehnâme’de geçen Acem kahramanlarından yararlanmıştır. Cemâlî’nin seçtiği bu kahramanlar “Acem” kahramanlar olarak bilinse de, başka kültür ve medeniyetlerde bu kahramanlara farklı şekillerde yer verildiğini görmek mümkündür. Örneğin Rüstem’in Çin de Yao, Yunan da Persee ve Herkül’ün bir sembolü olarak görülmesi bu sebepledir. Klâsik Türk edebiyatında yer alan efsanevî ve mitolojik şahsiyetlerin mensup olduğu Doğu ve Batı medeniyetleri arasında: Türk, Arap, Fars, Moğol, Çin, Yunan, Ermeni, Roma, Mısır, Sümer, Firik, Fenike, İskandinav ve Anadolu’da yaşamış kadim medeniyetler sayılabilir. Cemâlî divanında ise Acem kahramanların dışında farklı medeniyetlere mensup mitolojik, efsanevî ve aşk hikâyelerinin kahramanı olan şahsiyetlere de yer verilmiştir. Bu çalışmada Cemâlî’nin hayatı ve eserleri hakkında kısaca bilgi verilmiş ardından divanında yer alan mitolojik ve efsanevî şahsiyetler; “Acem Kaynaklı Şahsiyetler”, “Dinî ve Mitolojik Şahsiyetler”, “Aşk Hikâyelerinin Kahramanı Olan Şahsiyetler” olmak üzere üç başlık altında incelenmeye çalışılmıştır.

Authors: Hadi Saiful
Published: April 2024

This study aims to examine pé-sapéyan pappa tradition amongst the Madurese migrants. It explores the Qur’anic spiritual values embedded in this tradition. The data were gained through  observation to the informents’ life and interviews with them regarding their reasons for migration and the form of social learning that arises from such migration.  The selected informants are migrants from Talango Island and Ghili Genting who live in several big cities, such as Jakarta, Jogjakarta, Surabaya, and Malang. This study shows that pé-sapéyan pappa can change the Madurese migrants’ mindset, deepening their knowledge and experience in managing businesses to improve their quality of life according to shari'a guidelines. The Qur’an enjoins Muslims to seek a sustainable life to suport a better spiritual life. Most migrants established a small and medium entrepreneurship to generate more income. The tradition, which was originated from the migrants’ hometown, help create a model of social learning in the host city, from which the migrants learn how to deal with the new situation and settle challenges.
Altı Aylık Bebeklerde Demir Eksikliği Anemisi Sıklığı ve Demir Profilaksisi
Authors: Berber Melda , Sipahi Tansu
Published: April 2024

AMAÇ: Ankara ili hastanemiz yerleşim bölgesinde doğumdan itibaren sadece anne sütü almış, sağlıklı 6 aylık bebeklerde demir eksikliği (DE) ve demir eksikliği anemisinin (DEA) sıklığını saptamayı, demir profilaksisi verilmemiş aynı bebeklerde 1 yaşında demir eksikliği gelişip gelişmediğini test etmeyi amaçladık.
GEREÇ VE YÖNTEM: 2009- 2013 tarihlerinde izlenen anne sütü alan, demir desteği almayan, aylık kontrolleri yapılan sağlıklı 560 bebek alınmıştır. Olguların 6. Ayda tam kan sayımı ve demir parametrelerine bakılmıştır. Bebeklerden DE/DEA saptanmamış, demir desteği de verilmeyenlere 1 yaşında demir durumlarını tekrar değerlendirmek amacıyla aynı parametrelerine bakılıp 6. aydaki kanlarıyla karşılaştırılmıştır. Demir desteği almamasına rağmen ek gıdalar ve anne sütüyle beslenme sonucunda kan değerlerindeki değişiklikler gösterilmiştir.
BULGULAR: 560 bebeğin 6. aydaki hematolojik parametrelerine göre, %6,8 DE, %9,3 DEA saptanmıştır. DE/DEA saptanmayıp, profilaksi başlanmayanların 43’ünde 1 yaşında demir durumlarını tekrar değerlendirmek amacıyla hematolojik parametrelerine bakılmıştır. 6 ay ve 1 yaş kanları istatistiksel karşılaştırılmıştır. MCV, transferrin saturasyonu 1 yaşında anlamlı yüksek bulunması dışında diğer kan paremetrelerinde farklılık saptanmamıştır. İlk 6 ay anne sütü, 6. aydan sonra anne sütü ve yeterli ek gıda alan 43 vakada demir profilaksisi başlanmamasına rağmen 1. yaşında alınan hematolojik parametrelerden ferritin hariç hepsinde yükselme saptanmış fakat istatistiksel farklılık saptanmamıştır. Ferritindeki azalmaysa istatistiksel anlamlı bulunmamıştır
SONUÇ: Demir profilaksisi verilirken, DEA prevalansının değişiklik gösterebileceğini dikkate almak gerektiğinin önemli olduğu kanısındayız. Çalışmalara göre demir profilaksisinin gereksiz verilmesinin yan etkileri vardır. Bu durum çocukların nörobilişsel, motor fonksiyonlarını olumsuz etkileyebilmektedir. Bu etkilerden koruyabilmek için, ilk altı ay sadece anne sütüyle beslenen, altıncı aydan sonra anne sütüyle beraber yeterli ek gıda alan bebeklerin belli aralıklarla demir durumunun tespiti için hematolojik parametrelerine bakılmasının faydalı olabileceğini düşünmekteyiz.

Authors: Alfian Alfian , Nurliani Anni , Sundari Titik
Published: April 2024

In a broad sense, behavior is the visible actions carried out by living creatures to adapt to environmental conditions for survival. N. diardi borneensis is one of the endemic animals of Kalimantan and is considered the highest leader of the food chain in Kalimantan. The Bornean clouded leopard was once considered the same species as the clouded leopard (Neofelis nebulosa), but in 2006 it was classified as a different species. The Bornean clouded leopard, which is endangered, is very interesting as an object of observation. The presence of the Bornean clouded leopard in the South Kalimantan (Kalsel) BKSDA transit cage after evacuation is an opportunity to observe the behavior of this rare animal. This study aims to determine the behavior of N. diardi borneensis while in the South Kalimantan BKSDA transit cage as scientific information that can be used as a reference for preservation and conservation programs. The method used is observation using the focal animal sampling method. Observations are divided into three periods: in the morning from 08.00 – 09.00, in the afternoon from 12.00 – 13.00, and the afternoon from 16.00 – 17.00. In each period, observations were made for 1 hour with recording intervals, namely every 5-minute interval, to calculate the duration/time of the behavior and then calculate the percentage. The results obtained from observing the behavior of N. diardi borneensis for 14 days are the behavior shown by N. diardi borneensis during the transit drum, namely resting behavior with an average duration of 1883 minutes (75%), movement behavior with an average duration of 584 minutes (23%), and eating behavior with an average duration of 53 minutes (2%). The Bornean clouded leopard has a unique special behavior: spending most of its time doing activities on tree branches (arboreal).

Teaching thinking has been the focus of the new round of key competencies-oriented K-12 education reform in China. Based on the Concerns-Based Adoption Model (CBAM), this study investigated Chinese in-service teachers’ concerns about teaching thinking and how demographic variables affected their concerns. A questionnaire modified from the Stages of Concerns (SoC-TT) was used to collect the data. Altogether, 382 in-service teachers from 28 cities in China participated in this study by filling out the online questionnaire voluntarily and anonymously. The results showed that: (1) The modified seven-stage SoC-TT instrument showed satisfactory reliability and validity in the context of teaching thinking in China. (2) Teachers showed higher self-concerns (Informational and Personal) and impact concerns (Consequence, Collaboration, and Refocusing) while their task concerns (Management) about teaching thinking were relatively low. (3) Except for the Consequence stage, their demographic variables significantly influenced teachers’ concerns at other stages. Implications for professional development for teaching thinking were discussed.

Strains of gasteroid fungi are capable of oxidizing phenolic components and producing enzymes of great commercial value. However, the difficulty in producing biomass and, consequently, the low levels of expression of enzymes produced by these fungi hinder the advancement of biotechnological studies. A possible alternative may be supplementing the culture medium with lignocellulosic substrates, as observed in the cultivation of edible mushrooms, for example. Thus, the objective of this study was to analyze the effect of supplementing a potato-based culture medium with different concentrations of wheat and rice bran on mycelial development and the production of phenoloxidase enzymes of Amazonian strains of Cyathus and Geastrum. The basidiomas were collected in the Amazon of Pará, and the strains were obtained from mycelial isolation on Potato Dextrose Agar (PDA) medium. The strains were inoculated in semi-solid and liquid potato-based medium containing 10% and 20% rice bran and 10% and 20% wheat bran. For a period of 20 days, mycelial growth was observed in solid form, and for 40 days, the development of the strains in liquid medium was monitored, all incubated at 25°C in the dark. Growth and production of fresh and dry biomass were measured, as well as the production of phenoloxidase, arising from growth in liquid medium. Supplementation using 10% wheat bran was the most promising for the radial growth of four of the six species tested (C. limbatus, G. hirsutum, G. echinulatum, and G. schweinitzii), in addition to being the best treatment for the production of biomass and phenoloxidase enzymes for all species. Considering that wheat bran is easily accessible, this study stimulates basic science, especially in the Amazon, where Funga is still underestimated in terms of diversity and biotechnological potential.

For several decades, a protocol based on the use of progestagens has been used to manage livestock reproduction with minimal alterations. Recently, researchers have gained insight into the short-term use of progestagen protocols lasting 5-7 days, which has been found to reduce the incidence of vaginitis and obviate the use of antibiotics. Additionally, this approach enables the reutilization of silicone-based devices such as CIDRs after a thorough biosecurity assessment. However, these devices have certain limitations. At the end of the treatment, they must be disposed of and cannot be reused, necessitating a re-evaluation of their use for technical and societal reasons, including animal health and welfare, food safety, and environmental impact.A chitosan-PEG intravaginal implant formulation released progesterone for a period of four days, corresponding to the degradation time of the implant in the vagina. The use of a simple melting and molding process for the combination of PCL-PEG-chitosan implants has been observed to result in degradation of both simulated vaginal fluid and vaginal tissue of cows. The development of intravaginal devices made from biodegradable polymers is considered a potential solution because these materials would degrade within the body, eliminating the need for removal and leaving no residue. These devices are safe for animals and the environment.

Objective: This study aimed to investigate the use of fermented domesticated-type Moringa oleifera leaves (FDMOL) + yellow corn (YC) + rice bran (RB) + top mix (TM) with the provision of fish meal (FM) in replacement of partial commercial diet (CD) to broiler performances and carcass yields.

Methods: The study used 100 broiler chicks, unsex, MB 90 performed into Completely Randomized Design (CRD) consisting of 5 treatments and 4 replicates. The trial diets were: MCR= 84.5% CD + 5% FDMOL + 5% YC + 5% RB + 0.5% TM (moringa+), MCF= 84.5% CD + 5% FDMOL + 5% YC + 5% FM + 0.5% TM (moringa++), C1= 100% CD, C2= 84.5% CD + 7.5% YC + 7.5% RB + 0.5% TM, and C3 = 84.5% CD + 5% YC + 5% RB + 5% FM + 0.5% TM.

Results: Better adding fish meal into the FDMOL + YC rather than no fish meal in replacement of partial commercial diet to feed on the broilers. Most parameter performances and yields seemed not affected on broilers fed the FDMOL + YC base replacement diet, but the breast tended to reduce, then adding FM into FDMOL + YC relatively recovered this valuable part of cuts-up similar to the control.

Conclusion: Adding fish meal into fermented domesticated Moringa oleifera plus yellow corn in the diet did not affect performances but could recover the breast yield of broiler compared to those fed the moringa-based diet without adding fish meal.

Many studies have replicated the clinical and genetic features of polycystic ovarian syndrome (PCOS) using a range of experimental animal models to improve treatment outcomes. This article aims to present an overview of the various experimental animal models that have been used in PCOS research. In this study, we conducted a systematic review of relevant research articles on the induced animal model PCOS. We searched research articles in Indonesian and English published over the last five years through three databases: PubMed, ScienceDirect, Google Scholar. We use established inclusion and exclusion criteria to select suitable articles. Out of 19 research articles included in our systematic review, we found the animal model PCOS based Rotterdam criteria, PCOS-IR model, PCOS-Inflammation model, PCOS-Gut microbiota model and PCOS-syndrome metabolic model. Androgen agents such as testosterone propionate, free testosterone, DHEA, and letrozole, as well as sodium valproate, are effective in the induction of PCOS phenotypes based on the Rotterdam criteria (oligo/amenorrhea, hyperandrogenic, and polycystic ovaries).
A Data-Based Continuous and Predictive Viscosity Model for the Oil-Surfactant-Brine Microemulsion Phase

Published: April 2024

This study presents a computationally produced data-based model/correlation that can accurately estimate the magnitude and predict the peaks of microemulsion viscosity at dynamic reservoir conditions. Equilibrium molecular dynamics (MD) simulation is used on a decane-SDS-brine interfacial system to generate a dataset of viscosity values as a function of different temperatures, surfactant concentrations, and salinities. The viscosity testing and training data are computationally measured using the Einstein relation of the Green-Kubo formula. Several machine learning (ML) based regression algorithms, including K-nearest Neighbors (KNN), Support Vector regression (SVR), Multivariate Polynomial Regression (MLPR), Light Gradient Boosting Machine (LGBM), and Decision Tree (DT), are used to train the model. The SVR regression provides the best performputaance for our model compared to other methods with an R2 (0.978 and 0.963 for train and test data, respectively) and mean absolute error value (0.059 and 0.072 for train and test data, respectively). The chosen model is then used to predict microemulsion viscosity for different reservoir conditions. The proposed model aims to accurately estimate microemulsion viscosity at dynamic reservoir conditions with variable input parameters such as pressure, temperature, brine salinity, and surfactant concentration, enabling accurate estimation and prediction of the transport properties of reservoir fluids and present phases at reservoir conditions, which is key to achieving maximum recovery during chemical EOR.

This investigation focuses on contrasting surfactant huff ‘n’ puff (HnP) treatments in two Eagle Ford Shale wells, specifically examining the influence of a polylactic acid (PLA) diverter used in the second. This work demonstrates surfactants as an effective enhanced oil recovery (EOR) strategy and highlights how the treatment design can impact the recovery outcome.

This work presents an in-depth field analysis with supporting laboratory experiments and statistical modeling to evaluate the surfactant's performance in both wells. Laboratory tests assessed surfactant efficacy in altering wettability and facilitating spontaneous imbibition in the presence of the PLA diverter and with different Eagle Ford samples. Post-stimulation monitoring of produced water for total dissolved solids (TDS) and surfactant concentration demonstrates the extent of treatment dispersion to the formation. A statistical model established performance expectations in the absence of surfactant treatment as a basis for evaluating the effectiveness and uncertainty of EOR uplifts.

Both field trials demonstrated significant improvements to oil recovery, uplifting oil rates from two to five times the production rates before treatment. 95% of the injected surfactant remained adsorbed within the reservoir leading to improvements persisting with a continued recovery uplift extending beyond two years and incremental recoveries ranging from 2,200 to 4,000 barrels of oil. The implementation of a polylactic acid (PLA) diverter in the second trial succeeded in dispersing the treatment throughout high and low-conductivity fractures. This tailored approach led to a more moderate but sustained incremental oil recovery, highlighting the diverter's strategic impact for future stimulation designs. Additional laboratory results underscored that local variations in Eagle Ford reservoir characteristics and the altered fluid dynamics introduced by the PLA diverter did not substantially impact surfactant performance.

Crucially, this research elucidates the PLA diverter's impact on surfactant HnP treatment outcomes, expanding on design strategies for EOR in unconventional reservoirs. Despite limited improvements with diverter for this specific treatment, these findings indicate potential benefits of controlled diversion for larger treatments and higher producing wells. This contribution is pivotal for refining EOR methodologies, and optimizing surfactant treatments for effective and efficient recovery strategies tailored to the unique challenges of unconventional reservoirs.
