Molasses is a viscous by-product of refining sugarcane into sugar, that has been considered as a cheap source of raw material for industrial ethanol production. The experiment was designed to determine the optimal temperature for ethanol production using a specific fermentation process. Fermentation experiments were conducted using a standardized procedure with varying temperature conditions. Samples were collected and analyzed to measure ethanol concentration at each temperature point. In this study, the ability of ethanol production from molasses using Saccharomyces cerevisiae was investigated at different temperatures (32°C, 34°C, and 36°C) on the scales of 500 ml, 2000 ml molasses solution, and 34°C was selected as the appropriate temperature to carry out the fermentation scale at 5000 ml of molasses solution. Experiments were carried out in molasses with an initial sugar concentration of 85 Brix, pH of 4.5, and fermented for 3 days (72 hours). In the fermentation of 500 ml of molasses solution, Ethanol concentrations of 8.6, 9.4, and 7.5% (v/v) were achieved at 32, 34, and 36, respectively. The results of the ethanol production at 34°C from 2000 ml of molasses solution showed that the ethanol concentration was 9.7% (v/v), the level was high compared to other treatments at two other temperature ranges. Ethanol concentrations of 8.8% and 8.2% (v/v) were obtained at 32 and 36, respectively. From the results, 34°C was selected as the optimal temperature to carry out the fermentation experiment at the scale of 5000 ml of molasses solution with an ethanol concentration of 9.8% (v/v) was achieved. The study found that the optimal temperature for Saccharomyces cerevisiae to make ethanol at the pH of 4.5 was 34°C, yielding the highest amount of ethanol at 9.8% (v/v).

In order to lower the risk of worker injury during a particular activity, an analysis of all risks that were found to be impacting project performance from the railway construction sectors in the Eastern region of Nigeria was carried out. The data obtained from a self-administered questionnaire survey to the construction industries was calculated using Likert scale and the mean index formula following a brief instruction on health, safety, and environmental culture in the industry. Using a matrix analysis table and a qualitative approach of data analysis, the degree of dangers was ascertained. Five categories of dangers, together with their subcategories, were chosen from construction-related projects based on the mentioned literature. To ensure that every company in the research region was equally represented, three firms were chosen at random from each state. Employees in the chosen construction industry received 160 questionnaires in total. 44 did not answer for a variety of reasons, bringing the sample size down to 116. The rate of 72.5% for the respondent was found. Within two months, the distribution and collection were completed. Using the Cronbach's alpha reliability coefficient, which gauges the consistency of items in question replies, reliability tests were run on each hazard's scale. Social, physical, and chemical dangers have the highest level of hazard among the five categories of hazards mentioned. The findings corroborate the literature that shows the most dangerous conditions in the construction sectors within the analyzed locations include insufficient safety performance, lack of job security, dry cement, dust, vibration, and sun.

Quantum mechanical methods in computational chemistry
Authors:   Faculty of Engineering Kampala International University Uganda, Regina Odette Agnes
Published: August 2024

Quantum mechanical methods constitute the cornerstone of computational chemistry, providing unprecedented insights into molecular behaviour and properties at the atomic scale. These methods elucidate fundamental electronic structures, energies, and properties that are critical for understanding diverse chemical systems by solving the Schrödinger equation. Among these methods, Density Functional Theory (DFT) stands out for its versatility in investigating the electronic properties of atoms, molecules, and solids, rooted in the seminal Hohenberg-Kohn theorems and Kohn-Sham equations. This review explores the expansive landscape of quantum mechanical methods in computational chemistry, highlighting their pivotal role in advancing scientific understanding and technological innovation. Many areas, including material science, catalysis, and drug development, utilise these techniques to enhance molecular structures, forecast reactions, simulate spectroscopic properties, and clarify solvation effects. Quantum chemistry can now predict even more with the help of advanced techniques like post-Hartree-Fock methods and time-dependent DFT. These techniques give us more information about how molecules move and how electrons are excited. Molecular dynamics (MD) simulations add to quantum mechanical approaches by showing how molecules move and interact with each other over time. They achieve this by linking what scientists believe should occur theoretically with actual occurrences. Adding computer programs such as Structure-Based Drug Design (SBDD) and materials modelling shows how quantum chemistry can change things, speeding up the discovery process and improving the accuracy of molecular behaviour. Spectroscopy simulations and solvation studies help us predict how to interpret experimental data and figure out how the environment affects molecules' behaviour, and its applications thus making computational chemistry even more useful. The continual evolution of quantum chemistry software and high-performance computing frameworks democratises access to advanced computational tools, fostering collaboration and innovation in tackling complex scientific challenges. As quantum capabilities advance, the future promises even greater applications across chemistry and interdisciplinary fields, driving continual progress in materials design, drug development, and environmental sustainability.

Mechanism of action and selection of endoscopic bariatric therapies for treatment of obesity
Authors: Ghusn Wissam , Calderon Gerardo , Abu Dayyeh Barham K. , Acosta Andres
Published: August 2024

Endoscopic bariatric therapies (EBTs) are minimally invasive and safe procedures with favorable weight loss outcomes in obesity treatment. We aimed to present the weight loss mechanism of action of EBTs and an individualized selection method for patients with obesity. We searched PubMed, Medline, Scopus, Embase, and Google Scholar databases for studies on the topic from databases inception to July 1, 2023, written in English. We focused on EBTs potential mechanism of action to induce weight loss. We also present an expert opinion on a novel selection of EBTs based on their mechanism of action. EBTs can result in weight loss through variable mechanisms of action. They can induce earlier satiation, delay gastric emptying, restrict the accommodative response of the stomach, decrease caloric absorption, and alter the secretion of gastrointestinal hormones. Selecting EBTs may be guided through their mechanism of action by which patients with abnormal satiation may benefit more from tissue apposition devices and aspiration therapy while patients with fast gastric emptying may be better candidates for intragastric devices, endoscopic anastomosis devices, and duodenal mucosal resurfacing. Consequently, the selection of EBTs should be guided by the mechanism of action which is specific to each type of therapy.

Folk Of The North East India: Oral Narratives As A Pre-Position Mechanism In ‘Negativisation’ And ‘Typicalisation’ Of Characters In The Contemporary Darlong Civil Society
Authors: Merelin Darlong
Published: August 2024

Construction of characters in a literary piece has become a debatable topic in the 21st century especially that of a female, which the feminist world has been continuously stirring around aiming to break through the door of masculinity complex[1]. In fact, characters in folk literatures and fairy tales had served the world with the same purpose acknowledging its existence in a form of oral materials. The Darlong oral narratives is no exception to it where certain characters are considered conventional where as other are dumped as negative images. The article attempts to highlight the working mechanism of Darlong oral narratives in deification and villainization of characters in the present Darlong society rooted through their tales and other narratives where the likes of ‘Râlruanga’, ‘King of Sonabawr’, ‘Sulhlutea’, ‘Rimȇnhawii’ and others are celebrated as heroes and heroine. In the meantime, there are also characters whose names merely ornamented the tribe’s narratives and never really canonise for they perhaps lacked the virtues and vices that the above-mentioned characters possessed. It is interesting to note how these characters have influenced the present society in objectifying their respective characters.

Birds are a good indicator for identifying areas rich in biodiversity, including environmental changes and problems. The reduced number of birds also indicates environmental degradation. Birds play an important role in an ecosystem in maintaining biological balance. These roles include pollinating plants, controlling insect populations and playing a role in the dispersal of plant seeds. In fact, several species of birds are considered key species where their presence in an ecosystem can indirectly influence the existence of other species. Birds need a habitat that acts as a source of food, a place to socialize, reproduce, take shelter, rest and nest. The mangrove area in the Angke-Kapuk Muara Angke Protected Forest is an important bird area or Import Bird Area. The method used is the Visual Encounter Survey (VES). Each species of avifauna found at the observation location was recorded and counted. Bird watching is carried out in the morning at 06.30 – 09.30 WIB.

Analisis Karakteristik Kekeringan Di Nusa Tenggara Menggunakan Pengukuran Return Period
Authors: Helen Parkhurst
Published: August 2024

Sektor pertanian, terutama produksi tanaman pangan merupakan pilar perekonomian di Indonesia dengan sentra produksi berada di Nusa Tenggara. Salah satu penyebab penurunan produksi tanaman pangan adalah kekeringan yang disebabkan oleh perubahan iklim. Kekeringan dapat dihitung dengan Standardized Precipitation Index yang merupakan indeks untuk mengukur tingkat keparahan kekeringan suatu wilayah. Tingkat keparahan kekeringan suatu wilayah dapat mencapai nilai tertinggi yang dapat digunakan untuk memperkirakan periode kejadian kekeringan yang terjadi secara berulang. Selanjutnya hasil estimasi tersebut dapat digunakan untuk memperoleh nilai Return Period yang merupakan rata-rata waktu kekeringan yang terjadi dengan menentukan keparahan kekeringan maksimum. Untuk mengantisipasi kekeringan yang terjadi secara berulang, tujuan dari penelitian ini adalah melakukan identifikasi karakteristik kekeringan dari Return Period berdasarkan profil geografis Nusa Tenggara. Data yang digunakan adalah data observasi curah hujan bulanan selama periode tahun 1985 sampai 2014 yang menggambarkan kejadian kekeringan yang telah terjadi untuk masa sekarang dan data skenario curah hujan bulanan selama periode tahun 2016 sampai 2100 berdasarkan Representative Concentration Pathways yang menggambarkan iklim di masa akan datang. Hasil analisis data menunjukkan bahwa Return Period secara geografis memberikan gambaran untuk berbagai wilayah. Pada wilayah karakteristik iklim lebih basah terlihat adanya pengurangan curah hujan, sedangkan wilayah karakteristik iklim lebih kering tidak mengalami pengurangan curah hujan yang signifikan. Secara umum dapat diketahui bahwa beberapa tahun ke depan prediksi kekeringan Pulau Nusa Tenggara menunjukkan tingkat keparahan kekeringan yang tidak terlalu parah dengan periode berulang yang lebih sering terjadi.
