Benoa Bay is an estuary that gets input of waste and nutrients from six rivers and inderectly influenced water productivity in Benoa Bay. The nutrients flow from the river to domestic, industrial, and agricultural activities into Benoa Bay. The amount of nutrient inputs accumulated in Benoa Bay this could affect the chlorophyll-a consentrations. The purpose of this study was to determine the spatial distribution and influence nitrate and phosphate on chlorophyll-a concentration. Water surface sampling carried out on February 2019. The method used was purposive sampling and chlorophyll-a concentration was analysed using spectrophotometer Shimadzu UV-2600, based on the maximum absorption of four wavelengths (quadrichroic). The results showed that the chlorophyll-a concentration ranged from 0.22 - 8.53 g/m3 with an average of 5.58 g/m3. Nitrate concentration ranged from 0,004 - 0,180 mg/L with an average 0,107 mg/L. Phosphate concentration ranged from 0,005 - 0,229 mg/L with an average 0,101 mg/L. Spatial distributions of chlorophyll-a concentration in Benoa Bay higher in the estuary area compare to sea area. The different concentration of chlorophyll-a in Benoa Bay were affected by physical and biological processes. The result of statistic regression of the nitrate and phosphate influence on chlorophyll-a concentration in Benoa Bay was 39,2% (R² = 0.392) for nitrate, meanwile 20,5% (R² = 0.205) for phosphate.

Published: January 2023

Coral reefs play significant roles in both aspects of ecology and economy. However its status in Indonesian reefs is mainly moderate to poor condition. One of the alternative way to rehabilitate the damaged coral reef is coral transplantation. Acropora hyacinthus is one of export comodities for ornamental aquarium and important component of reef builder organisms. Studies showed that fragmentation causes stress on the coral donor as indicated by the excessive mucus production which in turn may affect the survival of the coral donors. This study aims to determine the growth and survival rates of donors based on the initial fragment sizes. A total of 5 coral donors of A. hyacinthus with relatively similar branch were fragmented into initial sizes of 30, 50 and 70 mm and the rests were controls. The growth was indicated by the increase in length which measured every two weeks for 12 weeks. The results showed that the absolute growth of coral donors were significantly different among initial sizes. The survival rate in the initial length of 30 mm (100%) was higher than those in 50 mm (80%) and 70 mm (80%).

Evaluating the perception of structural defects during implementation of RC T-beams
Authors: Bayoumi Elsaid
Published: January 2023

Most defects during construction projects are due to human errors which happen due to poor workmanship. This study involved 8 simply supported RC T-beams subjected to uniformly distributed load at both-edges of slab. The investigated parameters were the effect of malposition of slab reinforcement, unequal configuration of slab reinforcement and change in bar diameter of slab reinforcement. The experimental results showed that; malposition of slab reinforcement leads to a lower load carrying capacity of the slab and consequently flexural resistance decreased and slab deflection increased. The irregularity of the reinforcing bars in concrete slab affected the load carrying capacity of T-beam. Well-arranged distribution of reinforcement improves the ductile behavior of slab and reduced value of deflections at failure. Using reinforcing steel bars with diameters higher than 8mm in the reinforcement helped the slab to withstand more loads. The use of 10mm diameter in reinforcement of the slab enhances the serviceability of T-beams.

Published: January 2023

Design changes are inevitable in most projects. In many construction projects they may look not too complicated to be executed in front of computer models. The actual situation turned out to be the other way around. Apart from detailed changes in shop drawings, bill of quantity and specifications, administrative works related to the project are quite considerations. These mounted consequences would be more for short duration projects with government funding executed in the near end book period. The allocated execution period for short duration projects is not usually allowing rapid changes for the unexpected consequences. This paper presents what actually happens inside the project management during the contract change order process.

Authors: Segawa Masafumi , Inoue Tomohiro , Tsunoda Sho , Kanamaru Takuya , Okubo Seiji
Published: January 2023

Background:

Acute carotid stent thrombosis (ACST) is a rare but devastating complication for carotid artery stenting (CAS). That requires early diagnosis and immediate treatment. Although administration of drugs or endovascular treatment is the most widely used approach for patients with ACST, there is no consensus on the standard treatment of this disease.

Case Description:

The present study reports on an 80-year-old female patient with the right internal carotid artery stenosis (ICS) that had been followed up by ultrasonography for 8 years. Although the optimal medical treatment was followed, the patient’s right ICS worsened, and the patient was subsequently hospitalized for CAS. On the 12th day after CAS, left paralysis and dysarthria were observed. Head magnetic resonance imaging (MRI) showed acute obstruction of the stent and scattered cerebral infarction in the right cerebral hemisphere caused possibly by the discontinuation of temporary antiplatelet drug therapy as a means to prepare for embolectomy of the femoral artery. Stent removal and carotid endarterectomy (CEA) were selected as the appropriate treatment approach. CEA was performed with the precaution of stent removal and distal embolism, and complete recanalization was obtained. Postoperative head MRI showed no new findings of cerebral infarction, and the patients remained symptom-free after 6 months of postoperative follow-up.

Conclusion:

Stent removal with CEA could be an appropriate curative option in some cases with ACST except in patients at high risk of CEA and in the chronic phase after CAS.

Published: January 2023

Background:

Falcotentorial meningioma is a rare tumor of pineal region, arising from the dural folds where the tentorium and falx meet. Due to the deep location and near closeness to significant neurovascular structures, gross-total tumor resection in this area can be complicated. Pineal meningiomas can be resected using a variety of approaches; however, all these approaches are associated with a significant risk of postoperative complications.

Case Description:

A 50-year-old female patient who presented with several headaches and visual field defect and diagnosed with pineal region tumor is discussed in the case report. Patient was successfully managed surgically by combined supracerebellar infratentorial and right occipital interhemispheric approach. Cerebrospinal fluid circulation was restored after surgery and neurological defects were regressed.

Conclusion:

Our case shows that it is possible to completely remove giant falcotentorial meningiomas with minimal brain retraction, preserve the straight sinus and vein of Galen, and prevent neurological impairments by combining two approaches.

Published: January 2023

Industrial projects have a profound impact on society and environment in terms of risks, hazards and causing threat to humans, animals as well as plants due to the pollution caused by them. The main sources of air pollution are vehicle emissions, large-scale construction activities, industry, biomass burning, fuel adulteration and traffic congestion. This is an effort to assess the industrial air pollution near Hyderabad city (Deccan) through emission inventory of nearby industrial sources. Emission inventory comprises the type of industry, type of fuel, pollutant emission factor and point source characteristics such as stack height, stack diameter, exit-gas velocityand exit-gas temperature. The pollutant emission load is computed using meteorological data, pollutant emission factor and fuel consumption. Concentrations of the major pollutants from the industry are calculated using an Air Quality Model (AERMOD). The isopleths of these pollutant concentrations are superimposed on the study area map. The concentrations of SO2, NO2 and PM10 are predicted for the month June 2021 as 44.63μg/m3, 31.48μg/m3 and 33.796μg/m3 respectively. Similarly, for the month of August 2021, predicted values are 18.28μg/m3, 20.39μg/m3 and 25.30μg/m3. It is noticed that the pollutant concentrations are higher in June compared to the pollutant concentrations predicted in August month.

Published: January 2023

Plastics have long been overruling the environment affecting the living systems by entering into the food chain. Negligent and erroneous disposal supports plastic for wide distribution and extensive use in day to day life. The durability and non-degradability encourage the persistent accumulation of plastic waste as an active and major pollutant of the biosphere. Plastic pollution is ubiquitous and solicitude issue that need to be heeded in a war footing. Microorganisms are used as major stimulant for degradation; biodegradation is eco-friendly and cost effective approach. In order to increase the microbial degradation process, novel strains need to be identified and explored for effective degradation of plastics. This review is intended to exhibit the impacts of plastics on environment, associated health hazards and the current status of microbial degradation, challenges and scope for improvement.
Inducing Exraordinarily Piezoelectric Response via Homogeneous and Heterogeneous Functionalization of a Sc2C Nanosheet, A Quantum Chemical Investigation
Authors: El-Kelany Khaled , Abdel-Azeim Safwat , Kuehn Oliver , El-Zatahry Ahmed , Shibl Mohamed
Published: January 2023

Piezoelectricity is pivotal for applications in micro/nanoelectromechanical (MEMS/NEMS) systems. Inducing such property into the two-dimensional Sc2CTT′ MXenes (where T and T′ are the functionalization atoms) via homogeneous and heterogeneous surface functionalization is explored. The functionalization atoms T and T′ located at the upper and lower surfaces, respectively, are identical in the case of homogeneous functionalization, while they differ in the case of heterogeneous functionalization. Upon T and T′ exchange, an additional reverse heterogeneous configuration is generated. The heterogeneous functionalization of Sc2CT2 induces an extraordinary in-plane and out-of-plane piezoelectric effect owing to symmetry breaking. Interestingly, both heterogeneous and its reverse configuration show approximately identical geometrical, energetic, and even elastic properties, but rather different piezoelectric coefficients. The obtained piezoelectric effect is more than ten times larger than the experimentally measured piezoelectricity of MoS2-monolayer. Our study suggests a way toward more efficient nanoscale piezoelectric devices based on Sc2C MXenes.
The production of Biodiesel from Algae using flocculation & Nanoparticles
Authors: Ibrahim Gehad , Al Ghabra Lemar
Published: January 2023

Although fossil fuels propelled society to our current level of technology, the future of energy lies in renewable resources, beginning with vehicles. Despite accounting for only 5% of total vehicles in the US, medium to heavy-duty trucks that run on diesel fuel account for an astounding 23% of annual CO2 emissions in the transportation sector. The full implementation of greener biodiesel is frequently regarded as an impractical method of pollution reduction because the production of such biodiesel competes directly with the agricultural industry for available arable land. (“Optimizing Nannochloropsis Growing Conditions for ...”) Energy-dense algae are better biodiesel feedstocks because they avoid many of the issues that current biodiesel feedstocks do, and their potential can be used to propel the biodiesel industry into the future of sustainable energy. Because of its high productivity and lipid content, Nannochloropsis is a promising algae genus. The research shows how to quantify the constituent fatty acid type and composition in order to optimize the growing medium composition for increased biodiesel quality while maintaining high productivity (GC). The algae are grown in three 2.5 L glass jugs with three different nitrate and phosphate concentrations. Throughout the trials, a growing "1/2" medium is used. A flocculating solution of aluminum sulfate and vacuum filtration are used to harvest the algae. In situ transesterification is used to maximize fatty acid conversion into fatty acid methyl esters, which are then analyzed using GC. After 32 days of growth, the algae grown in low, medium, and high nutrient concentrations had average absorbance values (a measure of biomass concentration) at 750 nm of 0.91, 0.99, and 1.18, respectively. In a low nutrient concentration, the maximum monounsaturated fatty acid (MUFA) concentration of 62.68 percent of total fatty acids was achieved, corresponding to high-quality biodiesel. This study resulted in a scientific breakthrough by maximizing both the quality of biodiesel produced, which is superior to any currently available biodiesel, and the quantity, with a productivity that is more than one hundred times that of current biodiesel feedstocks. The research also discusses nano-technology application that concluded nanomaterials could stimulate microorganism metabolism, implying that including nanomaterials in cultivation could boost microalgae lipid production. Furthermore, the use of nanomaterials could improve the efficiency of lipid extraction while causing no harm to the microalgae., as well as the research needs and future directions for sustainable microalgal biofuel production. Since we did not have access to the materials needed, the information gathered in this study was culled from a variety of sources.
Implicating the Role of Au-H Bonds in Photochemical N2 Fixation by Ruthenium Doped Gold Clusters
Authors: SULTANA MUNIA , Paul Sayan , Paul Ankan
Published: January 2023

Dinitrogen fixation through the Nitrogen Reduction Reaction (NRR) under mild conditions without the use of sacrificial agents has its share of formidable hurdles. It has been shown recently that Ru-doped Au nanoclusters can reduce N2 molecule to NH3 only in the presence of UV-Vis light in aqueous medium. Herein, using theoretical techniques we shed light on the mechanistic avenues traversed for achieving this prodigious chemical feat. Our findings suggest that the bimetallic Au22Ru6 cluster successfully accomplishes the NRR process under ambient pressure and temperature conditions by the very virtue of its bifunctional nature. Contrary to the existing views, we find that NRR propagates through an unconventional associative pathway, where the Ru dopant assists in N2 adsorption while the Au-H bonds formed from Au assisted water splitting is implicated for facilitating NRR.

Agency, Stability, and Permeability in "Games"
Authors: Camp Elisabeth
Published: January 2023

In “Games and the Art of Agency,” Thi Nguyen argues that games both highlight and foster a profound complexity in human motivation, in the form of “purposeful and managed agential disunity.”  I agree that human agency is “fluid and fleeting” rather than stable and unified; but I argue that Nguyen’s analysis itself relies on a traditional conception of selves as enduring goal-driven agents which his discussion calls into question. Without this conception, games look more like life, and both look riskier, than we might otherwise hope.

Este tomo de Experiencias en las comunidades por la vida humana y el cuidado de la casa común. Sistematización de experiencias de Proyección Social de UNIMINUTO, no es un libro solo para leer y consultar, o para enviarlo a la biblioteca o las estanterías de nuestras oficinas, o para dejarlo guardado digitalmente en nuestros computadores, no, es un libro para revisar con nuestras comunidades académicas, para tomar algunas de las experiencias sistematizadas y llevarlas a la clase con nuestros estudiantes y profesores, para capitalizar lo que nos dicen con el fin de redunden en otras comunidades. Son experiencias sistematizadas para replicar, replantear, cualificar, mejorar, validar y discutir los saberes generados; son experiencias sistematizadas para socializarlas con los actores sociales con los que interactuamos; son experiencias sistematizadas para fortalecer y transformar la propia práctica, para construir nuevos sentidos, para entrar en contacto con los actores de las experiencias y crear redes, para impactar mejor en nuestros territorios, para animarnos a sistematizar nuestras experiencias en las comunidades y lograr generar nuevos aprendizajes.

Іноваційні технології в світі можуть покращити взаємодію з клієнтами, від відгуків яких залежить оцінка наданих послуг. Технології чат-ботів на основі штучного інтелекту можуть використовуватися для надання персоналізованих послуг, як-от створеня програми харчування та підтримки фізичних можливостей. Саме такий напрям автоматизації послуг індустрії набуває широкого розповсюдження в світі. У статті проведено аналіз зарубіжного досвіду розвитку процесів автоматизації послуг гостинності, визначено основні переваги та недоліки. На основі анкетування проведено оцінку якості сприйняття автоматизації процесів обслуговування молоддю. Визначено, що чат-боти краще виконують прості завдання, працюючи за відповідним алгоритмом, окрім того необхідно враховувати індивідуальні побажання людини, особливо якщо є потреба знайти нестандартне рішення. Визначено основні проблеми, з якими стикаються компанії індустрії гостинності під час впровадження автоматизації гостиності, проаналізовано можливості їх вирішення, а також доведено необхідність їх впровадження в сучасному світі та перспективи розвитку цього напряму.

У статі запропоновано один із напрямків оцінювання економічної ефективності з урахуванням нетрадиційних критеріїв, які набули розвитку при утилізації рідкісних металів в металургії спеціальних сталей. Показано значення питання раціонального використання сировинних та енергетичних ресурсів, використання техногенних відходів, вторинної сировини та утилізація цінних компонентів від їх переробки. Для підвищення ступеня утилізації використовували добавки легованого циклонного пилу, який осідає при диспергуванні рідкого металу. Оптимальні параметри металізації окалини в капсулах в нагрівальних печах разом з термообробленим металом дозволяють підвищити ступінь використання нагрівальних печей. Отриманий губчастий матеріал у капсулі використовується в якості легованої шихти при виробництві порошкових швидкорізальних сталей без будь-яких значимих змін до діючої технології, що дозволило істотно знизити витрати дорогих рідкісних елементів і феросплавів на їх основі. Виявлено чинники, які отримали розвиток і роблять визначальний вплив на економічну ефективність утилізації тугоплавких елементів при відносно низьких температурах (не більше 1200 °C) запропонованим способом. Визначені фактори, що впливають на ефективність вилучення рідкісних металів: концентрація тугоплавких елементів у використовуваних відходах, витратні коефіцієнти, ступінь їх наскрізної утилізації, зниження чаду всього комплексу тугоплавких і активних металів при веденні процесу в системах з надлишковим відновним потенціалом і інші чинники. Економічна доцільність утилізації рідкісних металів з окалини швидкорізальних сталей підтверджується розрахунками, виконаними основі статистичної обробки даних обліку діючого промислового виробництва сталей.

У роботі досліджено одержання нового легуючого матеріалу на основі вольфраму методами порошкової металургії, Проведені розрахунки та економічні оцінки виробництва та використання губчастого феровольфраму для легування спеціальних сталей. Розроблений технологічний регламент виробництва губчастого феровольфраму дозволяє його використання у якості легуючого матеріалу. Проведена оцінка економічної ефективності та визначені основні фактори які впливають на неї. До факторів, які чинять вплив на економічну ефективність, слід віднести: виключення використання в якості відновника коштовних порошків кремнію та алюмінію та заміни їх вуглецевмісними відходами; виключення операції поділення плавлених злитків, які знижують собівартість переділу відновлення рідких концентратів. При використанні губчастого вольфраму в якості легуючого матеріалу скорочується час розчинення вольфраму в розплаві, що знижує втрати вольфраму та інших легуючих елементів i розкислювачів та підвищує продуктивність основних металургійних агрегатів. Всі ці фактори знижують собівартість плавильного переділу. У роботі виконана оцінка економічної ефективності при одержанні губчастого феровольфраму і його використанні при виплавці швидкоріжучої сталі Р6М5 у дуговій електропечі ДСВ-25. При використанні нового легуючого матеріалу як легуючої добавки в розплав сталі одержують розвиток такі фактори як зниження видаткових коефіцієнтів на переділ плавки по вольфраму, хрому, молібдену й ванадію за рахунок зниження окисного потенціалу розплаву сталі, питомої витрати технологічної енергії при підвищенні швидкості засвоєння вольфраму розплавом сталі в 5–7 разів у порівнянні зі стандартним плавленим феровольфрамом й iн.
