Authors: Yang Junyu , Xu Qianghui , Kou Xuan , Wang Geng , Lei Timan , Wang Yi , Li Xiaosen , Luo Kai H.
Published: February 2024

Methane hydrate is a promising source of alternative energy. An in-depth understanding of the hydrate dissociation mechanism is crucial for the efficient extraction. In the present work, a comprehensive set of pore-scale numerical studies of hydrate dissociation mechanisms is presented. Pore-scale lattice Boltzmann (LB) models are proposed to simulate the multiphysics process during methane hydrate dissociation. The numerical simulations employ the actual hydrate sediment pore structure obtained by the micro-CT imaging. Experimental results of xenon hydrate dissociation are compared with the numerical simulations, indicating that the observed hydrate pore habits evolution is accurately captured by the proposed LB models. Furthermore, simulations of methane hydrate dissociation under different sediment water saturations, fluid flow rates and thermal conditions are conducted. Heat and mass transfer limitations both have significant effects on the methane hydrate dissociation rate. The bubble movement can further influence the dissociation process. Dissociation patterns can be divided into three categories, uniform, non-uniform and wormholing. The fluid flow impacts hydrate dissociation rates differently in three-dimensional real structures compared to two-dimensional idealized ones, influenced by variations in hydrate pore habits and flow properties. Finally, upscaling investigations are conducted to provide the permeability and kinetic models for the representative elementary volume (REV)-scale production forecast. Due to the difference in the hydrate pore habits and dissociation mechanisms, the three-dimensional upscaling results contrast with prior findings from two-dimensional studies. The present work provides a paradigm for pore-scale numerical simulation studies on the hydrate dissociation, which can offer theoretical guidance on efficient hydrate extraction.
Teaching and Learning in Secondary Schools Using Social Learning Theory
Authors:   Mbarara University of Science and Technology, Arishaba Emilly
Published: February 2024

The purpose of this desk research paper is to demonstrate the application of social learning theory to the field of education. According to the notion of social learning, people can pick up new behaviours by watching and copying the actions of others in social situations. It says that even in the lack of muscular reproduction or direct reinforcement, learning is a cognitive process that happens in a social setting and can happen only through observation or direct instruction. Vicarious reinforcement is the method via which learning happens when rewards and penalties are observed in addition to behaviour. Regular rewards for a given behaviour increase the likelihood that it will continue; on the other hand, frequent punishments increase the likelihood that a behaviour will stop. The idea stresses the significant roles of numerous internal processes in the learning individual, building upon classic behavioural theories that hold that behaviour is only controlled by reinforcements.

Authors: Mlinarič Zala , Munda Ana , Pongrac Barlovič Draženka
Published: February 2024

Izhodišča: Telemedicina lahko izboljša glikemične in porodne izide nosečnostne sladkorne bolezni (NSB), čeprav še ni jasno, za katere posameznice naj bi bila telemedicinska orodja najbolj primerna. Namen naše raziskave je bil preveriti povezavo nekaterih psiholoških dejavnikov z glikemičnimi parametri pri ženskah z NSB, ki smo jih spremljali s telemedicinsko obravnavo. Analizirati smo želeli zadovoljstvo nosečnic s telemedicinsko obravnavo in opredeliti osebnostne značilnosti žensk, ki jim telemedicinska obravnava bolj ustreza.Metode: Vključene nosečnice so izpolnile Vprašalnik Velikih pet (angl. Big Five Inventory, BFI) in Vprašalnik o opolnomočenju v zvezi z vodenjem sladkorne bolezni (angl. Diabetes Empowerment Scale, DES). Podatke o samomeritvah koncentracije glukoze v krvi smo pridobili iz glukometrov. Povezanost med spremenljivkami smo izračunali s Spearmanovim koeficientom korelacije (Spearman ρ).

Rezultati: V raziskavo je bilo vključenih 50 žensk (starost 32,0 ± 4,3 let) z NSB, ki so bile vodene telemedicinsko. Od osebnostnih dimenzij sta bili sprejemljivost (Spearman ρ=0.422, p=0.003) in vestnost (Spearman ρ = 0.346, p = 0.016) pozitivno povezani s skupno realizacijo meritev glukoze v krvi. Ugotovili smo povezavo med povprečno koncentracijo glukoze v krvi po obrokih in skupnim dosežkom pri Vprašalniku DES (Spearman q = 0.324, p = 0.030) ter dvema podlestvicama, tj. Obvladovanjem psihosocialnih vidikov NSB (Spearman q = 0.326, p = 0.029) in Nezadovoljstvom in pripravljenostjo na spremembe (Spearman q = 0.363, p = 0.014).

Zaključek: Naši rezultati predstavljajo korak k opredelitvi skupka psiholoških značilnosti žensk z NSB, ki bi lahko bil pomemben napovednik učinkovitosti telemedicinske obravnave. Potrebne so še nadaljnje raziskave, tudi o drugih psiholoških vidikih.
Incidentalom nadledvičnice – prava narava, razkrita zaradi težjega poteka covida-19

Published: February 2024

Incidentalom nadledvičnice je sprememba brez simptomov, naključno odkrita pri slikovnih preiskavah zaradi razlogov, ki ne vključujejo bolezni nadledvičnic. Njihova prevalenca strmo narašča na račun vedno večjega števila opravljenih slikovnih preiskav. Pretežno gre za benigne, hormonsko neaktivne adenome. Ob odkritju incidentaloma moramo razlikovati med benignimi in malignimi spremembami ter ugotoviti morebitno hormonsko aktivnost. Sodobno obravnavo incidentalomov predstavljava na izjemnem kliničnem primeru bolnice z drobnim incidentalomom leve nadledvičnice. Kljub visoki gostoti na nativni računalniški tomografiji (CT) smo na podlagi izplavljanja kontrasta v skladu s takratno prakso spremembo označili za benigno in odsvetovali nadaljnje morfološko spremljanje. Kljub temu je bolnica v naslednjih letih zaradi različnih zdravstvenih težav opravila več slikovnih preiskav, vendar spremembe velikosti tumorja ni bilo. Šele 6 let od odkritja so zaradi posledic covida-19 svetovali CT prsnega koša, ki je razkril izrazito rast tumorja. Bolnico smo napotili na levostransko laparoskopsko adrenalektomijo. Patohistološko je bil potrjen karcinom skorje nadledvične žleze, zato smo uvedli adjuvantno adrenolitično zdravljenje z mitotanom. Incidentalomi nadledvičnic so pretežno benigni in klinično nepomembni, včasih pa lahko ogrozijo življenje. Zato je pomembno, da jih obravnavamo v skladu s predstavljenimi smernicami. V izjemnih primerih z atipičnim potekom, kot je bilo pri naši bolnici, bo za ugoden razplet ključna obravnava v okviru interdisciplinarnega tima.

KONSEP KOMUNIKASI DAKWAH DALAM METODE PEMBINAAN PEMAHAMAN AL QUR’AN
Authors: Miftakhuddin
Published: February 2024

Berdakwah adalah proses mengkomunikasikan pesan-pesan Ilahiyah kepada orang lain. Agar pesan tersebut bisa dipahami dengan baik, diperlukan adanya penguasan komunikasi yang efektif. Muhammad SAW sebagai seorang utusan Allah SWT, punya tugas utama membawa kabar gembira dan memberi peringatan kepada seluruh umat manusia. Kegiatan penyampaian wahyu dan ajaran beriman kepada Allah biasanya disebut dakwah. Karena itu, perlu pengembangan paradigma dakwah, yang salah satunya adalah dengan memahami metode dakwah yang tepat untuk membina dan memahamkan Al-qur’an kepada umaat.

Metode dakwah yang dapat diimplementasikan dalam melakukan pembinaan dan pemahamaan Al-qur’an kepada umat. Ada beberapa metode dakwah yang bisa dilakukan. Pertama, metode Bil-hikmah kedua, Metode Mau’idzah Hasanah. Ketiga, Mujadalah billati hiyya ahsan. Al-Qur’an memberikan panduan tentang metode-metode dakwah untuk membina dan memahamkan Al-Qur’an kepada seluruh umat manusia, yaitu menyampaikan dengan lemah lembut dan perkataan-perkataan yang baik.

 Dengan demikian komunikasi Dakwah memegang peranan yang sangat penting di dalam menentukan dan memastikan seorang pembina pembawa risalah untuk senantiasa bekerja lebih produktif, efektif, dan efesien untuk mencapai tujuan yang sudah ditentukan. Tanpa komunikasi dakwah maka proses pembinaan tidak akan berlangsung dengan baik. Dalam konteks inilah dapat juga dikatakan bahwa pembinaan pada hakekatnya juga proses komunikasi secara terus menerus, dalam pengertian komunikasi dilakukan oleh seorang pembawa risalah ilahi.

Authors: Suchi Gamella Putri  , Tafdil Husni  , Rida Rahim
Published: February 2024

The aim of this research is to investigate the impact of investor sentiment on value and stocks return. Two investor sentiment indicators, volatility index VIX and sentiment index are used as independent variables. Technical proxies (relative strength index, psychological line index, trading volumes and adjusted turnover rate) are used to construct sentiment index using principal component analysis. The dependent variable is value and growth stocks return formed based on the book to market ratio. Three Fama-French factors are used as control variables to isolate the impact of investor sentiment from systematic risk and fundamental factors. We use companies listed on Kompas 100 index over the sample period February 2017-January 2023. The sampling technique was carried out by purposive sampling and obtained 45 companies as the research samples. The empirical analysis employs multiple regression analysis using 1.385 daily time series computed by Microsoft Excel and Stata 13. The regression results indicate that volatility index VIX has a negative significant effect on value and growth stocks return. Sentiment index has a positive and significant effect on value stocks return but does not have a significant effect on growth stocks return. Investor sentiment has a greater effect on value stocks than growth stocks.

Authors: Schwartz Anna L. , Helling Will , Griffin Stacy , Mikuls Stephanmie , Weber Brad
Published: February 2024

Background: Exercise is important for the health of people living with and beyond cancer. Yet most cancer survivors do not receive advice or referral to exercise oncology rehabilitation programs. A smartphone delivered exercise oncology app could minimize many of the barriers to exercise that these individuals face. Objective: To develop an exercise oncology application that provides a tailored exercise program (based on exercise history, current physical function, etc.) and adapts to user’s fatigue levels to minimize many of the barriers faced by clinicians, patients and people in underserved areas. Methods: The algorithms in the app were developed based on previous research. The individualized exercise prescription is based on the user’s daily level of fatigue, and if the user is on treatment, type and duration of treatment, and current fitness level. Results: Developed an easy to navigate, read and use app with reminders to exercise and positive feedback for reaching one’s goals. Conclusion: Cancer Exercise is a unique app that provides a tailored exercise oncology program for cancer survivors. Additional research is needed to see how the app may benefit people living in rural and underserved communities.
Correlational Analysis of Socioeconomic Status (SES) and Interfaith Harmony in Islamabad, Pakistan
Authors: Alam Muhammad Sardar , Farooqi Muhammad Rahmatullah , Hussain Majid Hussain Alias Ghalib
Published: February 2024

Religious acceptance extends beyond mere belief, encompassing the acknowledgment of rights, tolerance of worship freedom, and participation in political and educational realms. This phenomenon aims to foster mutual understanding through embracing diverse beliefs and values. In today's society, marked by escalating political and personal discord, interfaith harmony emerges as a pathway to peace. Embracing religious acceptance implies that coexistence can counter the rising tide of aggression by emphasizing shared elements of peace among different faiths. This study explores the correlation between religion and socioeconomic status (SES) in the context of G-7/2, Islamabad, Pakistan. SES, comprising education and income, was examined for its impact on interfaith harmony. The sample, drawn from the residential population of Muslims and Christians in the neighborhood, revealed a moderately positive correlation of 4.81**. Notably, education emerged as a primary factor, suggesting that enhancing SES could mitigate extremism and intolerance, with education playing a pivotal role in promoting interfaith harmony. These findings underscore the potential for socio-economic interventions to contribute to fostering a more harmonious coexistence among diverse religious communities.

С продолжающимся расширением сферы применения концепции социального капитала существенно активизируется критика концепций социального капитала. Основные дискуссии ведутся по содержанию концепций социального капитала П. Бурдье и Дж. Коулмана. Автором сделан вывод о том, что основной проблемой, определяющей различия в подходах указанных авторов, является его неконтекстуализированное применение без учёта их теоретических и эпистемологических основ. Подобная эклектика в понимании социального капитала обусловлена номинальным совпадением содержания понятий, обоснованных в работах Дж. Коулмана и П. Бурдье, имеющих разные значения. Автором обосновано предположение о целесообразности разработки единой теории социального капитала как социального ресурса управления организациями.

Published: February 2024

Palm oil methyl esters (POMEs) showed high induction period (IP) of 21.15 h whereas Jatropha oil methyl esters (JOMEs) exhibitedsignificantly lower value of 4.6 h. The IP of JOMEs was improved during the blending with POMEs. Gas Chromatography (GC) analysis ofblended biodiesel indicated the reduction in saturated fatty acids and increase in unsaturated fatty acids as compared to pure POMEs. Due toreduction in saturated fatty acids of blended biodiesel, a significant improvement was observed in the cold flow properties. Moreover,important fuel properties i.e. kinematic viscosity, water content, density and acid values of POMEs and JOMEs and their blends weredetermined. All the tested fuel properties were within the specified permissible limits of biodiesel standards (ASTM D6751 and EN 14214).

Authors: Sinha A. S. K. , Jazie Ali A. , Pramanik H.
Published: February 2024

The characteristics of peanut and rapeseed including high oil content, favorable fatty acid composition, low agricultural inputs, definable growing season, and uniform seed maturation rates makes them a good source for biodiesel production. Thus, the transesterification process to produce biodiesel from peanut oil and rapeseed oil was studied. This process gives yields of (95 % and 88 %) from peanut oil and (97 %, 92 %) from rapeseed oil using potassium hydroxide (KOH) and sodium hydroxide (NaOH) as a catalyst, respectively. Biodiesel yields were analyzed using the FTIR (Fourier Transform Mid-IR) spectroscopy method. Biodiesel yields from peanut oil and rapeseed oil at different conditions were investigated in order to optimize the process. Response surface methodology (RSM) was used to optimize the process parameters of the transesterification reaction. The models showed a good agreement with the experimental results, demonstrating that this methodology was useful for optimization. The models were successful in explaining the variation of response with respect to the three process parameters studied. The fuel properties of biodiesel produced were compared with ASTM standards for biodiesel.

EFFECT OF EXTRACTIVES ON THE THERMAL DECOMPOSITION OF WHEAT, TRITICALE, AND FLAX CROP RESIDUES : A KINETIC STUDY
Authors: Ross Kelly , Godfrey David
Published: February 2024

A kinetic study was performed using the Kissinger and Coats-Redfern methods to examine the effect of extractives on thermal decomposition of three crop residues, wheat straw, triticale straw and flax shives. The extractives-free crop residues required higher temperatures for the onset of thermal decomposition than the corresponding native/unextracted samples. Activation energy (Ea) values varied according to kinetic analysis and the extractives-free samples generally showed significantly higher Ea values (65-214 kJ.mol-1) than the native/unextracted samples (58-205 kJ.mol-1). This information is necessary for defining the use of crop residues as agro-fillers in composite materials and feedstock for bioenergy and biochemical via pyrolysis.

Keywords: wheat straw, triticale straw, flax shives, extractives, thermal decomposition, kinetic analysis, Kissinger method, Coats-Redfern method, activation energy.

Published: February 2024

Removal of malachite green oxalate from aqueous solutions by adsorption on Hevea Brasiliensis (a type of rubber wood) sawdust was studied experimentally. The aim of this study is to evaluate the bio-adsorbent as a green alternative for the removal of malachite green oxalate. Furthermore, to examine the factors that influence the adsorption of malachite green oxalate such as adsorbent particle size (54 to 750 μm in average), initial pH (3 to 9) and temperature (30 to 80 °C). Results showed that smaller particle size, higher pH and higher temperature are favorable for this adsorptive removal. Investigation of different equilibrium isotherms showed that the adsorption of malachite green oxalate on rubber wood sawdust takes place as the Langmuir adsorption. Comparison of the present result with other bio-adsorbents showed a compatitive adsorption capacity for the removal of malachite green. Keywords: Adsorption; malachite green; hevea brasiliensis; bio-adsorbent; wastewater; Langmuir model; Freundlich model.

Authors: Sahito Abdul Razaque , Mahar Rasool Bux , Siddiqui Zuhaib , Brohi Khan Muhammad
Published: February 2024

The gross calorific value (GCV) is the most important property of any fuel, which shows its energy content. The experimental determination of GCV of solid fuels is a cost intensive process, as it requires exceptional equipment and high skills. To streamline the task, many equations were developed in past for determining GCV from proximate and ultimate analysis of solid fuels. In present study two empirical equations were developed to predict the GCV of lignocellulosic biomass using their volatile solids (VS) and fixed solids (FS) with and without ash contents in specified range of VS (60.84–82.64 %), FS (17.36–39.16 %) and ash (1.59–21.76 %) as percentage dry mass basis. The experimental data was analyzed through multiple regression analysis and least square method. The empirical equations were developed and their mean errors were determined. The developed empirical equations are simpler, economical, less time consuming and are more accurate compare to the equations based on the proximate analysis.

Published: February 2024

In order to produce biodiesel continuously from waste cooking oil (WCO), a two-step process with microtube reactors (MRs) was developed. Esterification of fatty acid using acid catalyst proceeded in the first MR and then, the acid methanol phase as well as produced water was continuously separated from the oil phase in a simple separation cell, and finally, the oil phase flowed into the second MR for the transesterification of the remained triglyceride using KOH catalyst. It is found that the acidic methanol phase can be separated from the oil phase using a simple separation cell located downstream of the first MR in a short period. FAME yield reached 99.3 % at a total residence time of 46.2 min with a reaction temperature of 333 K, when WCO containing 14 mol% of free fatty acid was converted in the two-step reaction system composed of a first MR with 5000 mm length and a second MR with 1000 mm length.

Published: February 2024

In this report, the effect of tar decomposition on gas generation during pyrolysis in a packed bed of woody biomass was studied experimentally and numerically. The setting temperature of the furnace, TS, was changed from 673 K to 1073 K. The diameter of the biomass particles, DP, was changed from 0.34 mm to 1.13 mm. The heating rate of the furnace was 400 K /hr. From the experimental results, the mass flow rate of generated gas reached a maximum at a certain time t = tmax for TS > 773 K due to the secondary decomposition of tar. The tmax became longer as the diameter of the biomass decreased. The reasons for this finding are as follows. The thermal diffusivity of nitrogen is greater than that of biomass. The porosity in the packed bed for small particles is less than that for large particles. So the gas temperature in the bed decreased as the particles became smaller. Therefore, the tmax got longer for smaller particles. The calculated gas flow rate with the effects of temperature distribution and tar decomposition during pyrolysis in the packed bed mostly agreed with the results of the experimental model. Furthermore, in order to understand the chemical reactions during pyrolysis, it is necessary to include not only gas phase reactions but also fluid flow in the numerical model.

REVIEW OF THE POTENTIAL FOR CO-FIRING OF CASSAVA RHIZOME FOR GENERATING HEAT AND POWER IN CASSAVA BASED BIO-ETHANOL PLANT IN THAILAND
Authors: Prakobboon Natikorn , Vahdati Maria
Published: February 2024

Biomass is an important source of energy in Thailand and is currently the main renewable energy source, accounting for 40% of the renewable energy used. The Department of Alternative Energy and Eciency (DEDE), Ministry of Thailand, has been promoting the use of renewable energy in Thailand for the past decade. The new target for renewable energy usage in the country is set at 25% of the final energy demand in 2021. Thailand is the world’s fourth largest producer of cassava and this results in the production of significant amounts of cassava rhizome which is a waste product. Cassava rhizome has the potential to be co-fired with coal for the production of heat and power. With suitable co-firing ratios, little modification will be required in the co-firing technology. This review article is concerned with an investigation of the feasibility of co-firing cassava rhizome in a combined heat and power system for a cassava based bio-ethanol plant in Thailand. Enhanced use of cassava rhizome for heat and power production could potentially contribute to a reduction of greenhouse gas emissions and costs, and would help the country to meet the 2021 renewable energy target.

Published: February 2024

This study investigates the suitability of using commercial activated carbon developed from coconut shell in tap water filtration. Turbidity and metal content were analyzed with respect to the different cleansing agent and activated carbon dosage used in the filtration. The results showed that activated carbon cleansed using potassium hydroxide, zinc chloride or iron chloride, improved the taste of water. It was also found that as the dosage of activated carbon was increased, the taste enhanced and the metal content decreased suggesting the taste of water is inversely proportional to metal content of the water.

Published: February 2024

This paper reviews forestry biomass specifically material derived from natural forest, plantation forest, and rubber plantation of Malaysia, material collected upon log production and primary wood manufacturing activities. The information helps to foresee the potential of these promising waste resources to be used for energy products. As Malaysia forest covers from inland to coastal vegetation and natural forest as well as forest plantations plus rubberwood plantation in Peninsular, Sabah and Sarawak, therefore, a lot of residues have been generated. It is estimated that the total number of energy generated from waste in 2012 is 0.720, 0.381, and 1.657 Mtoe of Peninsular, Sabah, and Sarawak respectively. As Malaysia is expected to grow in population and economy, hence, sourcing an alternative for energy feedstock and biomass industry is crucial and forestry based biomass are seen as an opportunity.

Published: February 2024

A significant amount of pigment was isolated from a mycorrhizal fungus collected from a pine forest in Japan. The pigment was identified as norbadione A (NBA) by NMR spectrometry. Morphological characterization of the fungus and SEM observation of their basidiospores suggested the fungus was identified as Pisolithus sp. After solvent extraction and simple purification steps, NBA made up over 10% of the mushroom’s dry body weight. NBA is known to form Cs ion complexes more selectively compared to other alkali metal ions. The authors passed NBA through a Solid-Phase Extraction (SPE) column, and the NBA supported SPE column underwent Cs ion adsorption and desorption experiments. The column was shown to adsorb Cs in diluted aqueous solution, as well as successfully recover the Cs ion with diluted hydrochloric acid. The results suggest that an NBA supported SPE system can be a potential option for decontamination of radioactive pollution caused by nuclear plant accidents.

Effects of distillation process on antioxidant activity of Japanese traditional spirits rice-shochu
Authors: Saigusa Noriaki , Teramoto Yuji
Published: February 2024

In this study we investigated the effects of the distillation process on the antioxidant activity of Japanese traditional spirits “riceshochu”, particularly focusing on DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging activity and lipid peroxidation inhibitory activity. Using polished rice, white-koji (Aspergillus kawachii) and S-2 yeast (Saccharomyces cerevisiae), we prepared rice-shochu using both vacuum- and atmospheric-distillation processes. The lipid peroxidation inhibitory activity of vacuum-distilled shochu was 8.2 (± 0.4) μM BHT eq., whereas that of atmospheric-distilled shochu was 12.3 (±0.7) μM BHT eq., representing a significant difference (p<0.01). However, DPPH radical scavenging activity of vacuum-distilled shochu was 3.9 (± 1.2) μM Trolox eq., whereas that of atmospheric-distilled shochu was 3.4 (±0.1) μM Trolox eq., representing no significant difference (p<0.01). Furthermore, we analyzed the absorption spectra of both types of shochu and observed a common absorption maximum at 260 nm. Notably, the absorption values of the atmospheric-distilled shochu were higher than that of vacuum-distilled shochu. In addition, HPLC analysis of potential components with absorption maximum at 260 nm identified two peaks in the atmospheric-distilled shochu that were not detected in the vacuum-distilled shochu.
