Working To Solve the Permian Gas Conundrum
Authors: Wright Blake
Published: June 2024

Reflecting on oilfield history as a whole, it wasn’t all that long ago that natural gas was treated more like a nuisance than a commodity, either an undesirable byproduct of an oil discovery or a letdown when it was encountered in a well instead of the targeted black gold.

It can complicate things when an operator is drilling for oil, especially during periods like now when crude prices are robust, but gas prices aren’t. Additionally, when oil is discovered, it often comes with associated natural gas. When producers turn the taps to get that oil into sales lines, the gas can be problematic if the limited takeaway capacity for transporting it is already stretched.

This is the current situation for many operators in the prolific Permian Basin of west Texas and south-east New Mexico.

Infrastructure constraints to ship natural gas out of the Permian combined with high storage levels due to a relatively mild winter are wreaking natural gas pricing in the region. Natural gas prices at the WAHA hub located near Fort Stockton, Texas, were below zero—negative $4.60/MMBtu as recently early May.

Not only did that mean that produced gas in the region was basically free, but the negative price also meant producers trying to move gas out of the region would have to pay someone extra to do it. That’s not good business. Of course, anyone looking to chase that offer would find no pipeline capacity to move the product.

The US Energy Information Administration (EIA) said in December 2023 that production of associated natural gas has nearly tripled since 2018 in the three top-producing tight oil plays in the Permian region. Associated natural gas from the Wolfcamp, Spraberry, and Bone Spring plays averaged a combined 13.7 Bcf/D in the first 7 months of 2023, up from an average of 4.7 Bcf/D in 2018, according to data from Enverus. Associated natural gas production has grown due to increases in both crude oil production and the volume of natural gas per barrel of oil that a well produces, the gas/oil ratio, among the oil wells in these three plays.

The cavalry is on the horizon, however. A handful of high-capacity Permian natural gas export projects are moving through various stages of development and aim be operational over the next few years.

First up is the giant Matterhorn Express pipeline, which will move gas from west Texas to Katy, Texas (just west of Houston) and connect with other pipelines. The project, led by WhiteWater Midstream, EnLink Midstream, Devon Energy, and MPLX, is roughly 80% complete and should come online in the second half of this year.

Energy Transfer’s Warrior pipeline is loading up on transport commitments and will move gas from the Permian to the Gulf Coast. This system is on track for a potential late-2024 final investment decision (FID).
Hydraulic Fracturing Optimizes Extraction of Reservoir Initially Considered Secondary

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 213110, “Hydrocarbon Production Enhancement on the Apaika-Nenke Field by Applying Hydraulic Fracturing as a Tool To Optimize the Extraction of Reservoir M2 Considered Initially as a Secondary Target,” by Franck Salazar and Nestor D. Vasconez, Schlumberger, and Christopher J. Mayorga, SPE, Petroecuador, et al. The paper has not been peer reviewed.

_

As a result of reservoir conditions in Ecuador’s Apaika-Nenke field, a hydraulic fracturing pilot project was executed with the aim of maximizing production. After an analysis of the laminated reservoirs, a technique was implemented that generates higher fracture conductivity to reduce the drawdown during production and improve the connection through the laminations. The successful implementation of channel fracturing led to this technique becoming the preferred completion method in the field for wells requiring stimulation.

Introduction

The Apaika-Nenke structure is in Orellana Province of the Amazonian region inside of Block 31. Initial production tests in Well Apaika-1X showed an oil rate of 1,201 BOPD from the M1 reservoir and 653 BOPD from the M2 reservoir. In the Nenke-1X well, the oil rate was 1,600 BOPD from M1 and 328 BOPD from M2. Because higher oil rates were obtained from M1, the development phase that began in 2013 targeted the M1 reservoir as its primary objective. However, Well Apaika-A14 produced 150 BOPD only from the M2 reservoir. The maximum production from the oil field was 22,107 BOPD from M1 and 262 BOPD from M2 in April 2016 but has declined to 2,692 BOPD from M1 and 657 BOPD from M2.

M1 is the main producing reservoir in Apaika-Nenke, which produces using conventional techniques. M2, however, was treated as a secondary target with low and difficult production levels; production from Well Apaika-A14 required hydraulic fracturing to reach commercial levels. This well raised the possibility of hydraulic fracturing in the M2 reservoir, opening doors for targets previously considered secondary.

Reservoir Characteristics

M2 is a highly shale-laminated sandstone with a glauconitic sequence. Shale/sandstone intercalations are found within the pay zone, a key feature for hydraulic fracturing.

Well Apaika-A14 in M2 produces 14.9 °API oil with salinity levels on the order of 2,000 ppm chloride, while Well Nenke-B1 produces 16.3 °API oil and salinity levels of 9,000-ppm chloride. Well Nenke-B2 produces 14.7 °API oil with salinity levels of 5,600-ppm chloride. This information indicates that the oil producing from M2 is heavy. The oil viscosity is 104 cp at 194°F.

A pore/volume/temperature analysis shows that the oil in the M2 reservoir is undersaturated and produces above the reported bubblepoint of 320 psi. The original reservoir pressure was 2,760 psi before initiation of hydraulic fracturing.
eIF5A and hypusination-related disorders: literature review and case report of DOHH-related encephalopathy.
Authors: Beltrán-Corbellini Álvaro , Valls-Carbó Adrián , Toledano Rafael , García-Morales Irene , Román Irene Sánchez-Miranda , Gil-Nagel Antonio
Published: June 2024

Background
Eukaryotic initiation factor 5A (eIF5A) and hypusination-related disorders (eIF5A-HRD) are recently described diseases caused by pathogenic heterozygous variants in the translation factor EIF5A or biallelic variants in the two enzymes involved in the post-translational synthesis of hypusine in the eIF5A precursor, deoxyhypusine synthase (DHPS) and deoxyhypusine hydroxylase (DOHH), necessary for its activation. We review the current knowledge regarding eIF5A-HRD, and report the case of the sixth and oldest known patient with DOHH-related disorder (DOHH-D), aiming to expand and discuss the molecular basis and the general and epilepsy phenotypes of this group of diseases.
Results
Literature review yielded one paper describing 7 individuals with eIF5A-related disorders (eIF5A-D), one reporting 5 subjects with DHPS-related disorders (DHPS-D) and one characterizing 5 individuals with DOHH-D. Main phenotypic features consisted of prenatal issues, hypotonia, dysmorphisms, microcephaly, moderate-severe neurodevelopmental disorders/intellectual disability and behavioral disorders. We report the case of a 24-years-old male with DOHH-D manifesting as Dravet-like syndrome. He displays microcephaly and neurodevelopmental delay with attention deficit with hyperactivity disorder, along with a happy demeanor. Basic language skills and ambulation capacity with crouch gait are preserved. Onset of epilepsy was at 8 months with refractory temperature-triggered hemiclonic seizures and status epilepticus, followed by nocturnal tonic-clonic seizures from adolescence. Fenfluramine was the most effective approach, reducing seizure intensity, duration and frequency, and contributing to cognitive and behavior improvements. No patient with eIF5A-D presented seizures. Taking our patient into account, 4/5 and 4/6 reported individuals with DHPS-D and DOHH-D, respectively, presented epilepsy. Seven out of 8 epilepsy patients debuted between 2 and 5 years, most of them presented developmental and epileptic encephalopathies or generalized epilepsies (5/8 with temperature or infection-triggered seizures), and 4/8 were refractory. We hypothesize that dysregulation of PRRT2 and EEF2K might contribute to the eIF5A-HRD phenotype.
Conclusions
eIF5A-HRD are recently described entities displaying neurodevelopmental disorders and microcephaly, and reported patients are scarce. More than 70% of DHPS-D and DOHH-D patients present epilepsy, 63% of them with temperature-triggered seizures. Valproic acid or fenfluramine may be effective. Rare homozygous or compound heterozygous missense variants in these genes should be screened in patients with encephalopathy and temperature-triggered seizures.

Published: June 2024

Background
Cotton Leaf Curl Virus Disease (CLCuD) is one of the major concerns for cotton growers. The traditional approach to managing CLCuD involves the control of the vector (whitefly) population through the use of pesticides. In this study, the efficacy of nanoparticles was compared with pesticides. The present study was conducted to evaluate the comparative efficacy of zinc oxide nanoparticles (ZnO nanoparticles), iron oxide nanoparticles (FeO nanoparticles), copper nanoparticles (Cu nanoparticles) and silver nanoparticles (Ag nanoparticles). Optimized doses of zinc oxide nanoparticles (ZnO nanoparticles), iron oxide nanoparticles (FeO nanoparticles), copper nanoparticles (Cu nanoparticles) and silver nanoparticles (Ag nanoparticles) were applied in a field trial of cotton against Cotton Leaf Curl Virus Disease (CLCuD) in cotton. The study consisted of morphological parameters (height of stem, monopodial branches, sympodial branches, staple length, boll weight and number of bolls), yield parameters (seed cotton yield and ginning outturn), chlorophyll content (chlorophyll a, chlorophyll b, carotenoids and total chlorophyll), biochemical parameters (superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX), catalase (CAT), hydrogen peroxide (H2O2) and electrolyte leakage) and disease parameters (reduction infection, disease severity and disease incidence).
Results
Cotton Leaf Curl Virus (CLCuV) was detected by TAS-ELISA (Triple Antibody Sandwich-Enzyme-linked immunosorbent assay). Pesticide reduced the infection as 79.3%. Zinc oxide nanoparticles (ZnO nanoparticles), iron oxide nanoparticles (FeO nanoparticles), copper nanoparticles (Cu nanoparticles) and silver nanoparticles (Ag nanoparticles) reduced the infection as 42.33%, 41%, 34.7% and 44.8% respectively. The statistical design for field trial was randomized complete block design (RCBD). One-way ANOVA was performed.
Conclusion
Although treatment pesticide showed the least disease incidence compared to nanoparticles. Nanoparticles are eco-friendly and safe as compared to pesticides. It is concluded that nanocomposites and hybrid modes may be used for managing CLCuD efficiently in the future.

Objective:Death coping ability is a critical professional skill for palliative care nurses. This study aimed to identify subgroups of death coping ability among Chinese palliative care nurses based on their assessments using the Death Coping Ability Scale, and to analyze the relationship between these subgroups and their emotional labor.
Method:Convenient sampling was employed to survey 868 palliative care nurses from medical institutions in Beijing, Jiangsu Province, Anhui Province, and Hunan Province. Data was collected using a general information questionnaire, the Chinese version of the Death Coping Ability Scale, and the Emotional Labor Scale. Latent profile analysis was conducted to categorize the nurses' death coping abilities, and differences in emotional labor among these categories were compared.
Results:The death coping ability of palliative care nurses was categorized into three groups: "low death coping ability group" (11.5%), "medium death coping ability group" (52.0%), and "high death coping ability group" (36.5%). Factors influencing these categories included specialization in palliative care, opportunities for interaction with the bereaved, participation in grief counseling training, and personal bereavement experiences, all statistically significant (p < 0.05). Notably, there were significant differences in emotional labor scores among the three groups (F=33.006, p < 0.001).
Conclusions: The death coping ability of palliative care nurses can be classified into three distinct categories, each associated with different levels of emotional labor. Nursing managers should recognize these differences and implement targeted, personalized interventions to enhance the death coping abilities of palliative care nurses.

Indonesian EFL Learnersâ€™ Refusal: Refusal-Speech Act Specific Motivation on Refusal Realization
Authors: Dwiana Nadya Rezkhita , Syahri Indawan
Published: June 2024

Knowing how to produce speech act especially refusal appropriately is necessary since it is known as â€˜face-threateningâ€™ act, otherwise it would lead to discomfort between interlocutors. This ability may be influenced by many factors, one of which is motivation. One of the pragmatic motivation types is Speech Act Specific Motivation (SASM), which was found to have explanatory power to predict production of a certain speech act. This study aimed to investigate the correlation between learnersâ€™ refusal-SASM and their refusal. The subject was the students of English Education Program of Universitas Muhammadiyah Palembang. Discourse Completion Task (DCT) and refusal-SASM questionnaire were used in collecting the data needed. The results showed that the correlation between the two variables was insignificant, the refusal-SASM contributed only 3% towards the learnersâ€™ refusal. The recent study also found that the leaners tended to use indirect strategy in refusing to almost all situations. The reason of this phenomenon is likely to be the influence of L1 culture. However, further studies are highly suggested in this matter.

Syntactic Analysis of Makassar Question Words: An X-Bar Theory Approach
Authors: Rahmah Aisyah Tiara , Subiyanto Agus
Published: June 2024

This article endeavors to scrutinize the creation and functionalities of interrogative constructions, with a specific emphasis on the Makassar Language. The research design employed in this study involved the use of primary sources and followed a descriptive approach. Data collection was carried out through conversations with Makassar participants. To analyze the syntactic data, the study adopted X-Bar Theory as its theoretical foundation, which was then depicted in the form of syntax trees. The findings of this study indicated that the Makassar Language serves two grammatical functions, namely as a specifier and a complement. The highest level of projection in this structure was the Complementizer Phrase/CP. The distinction between these functions lay in the placement of question words. When a question word was positioned at the beginning of a sentence, it functioned as a specifier and followed the interrogative structure rule of QW + Subject + Predicate + Adv (optional). On the other hand, question words that required an answer other than the subject or were positioned at the end of a sentence were referred to as complementary functions. In this function, the researcher identified the pattern where the structure was written as Subject + Predicate + QW. X-Bar theory also helps in teaching syntax which needs a lot practice including creating tree diagrams of sentences to parse each constituent that requires a platform or program that can lead the students to diagramming

Published: June 2024

In the post-COVID-19 era, lecturers frequently employ internet tools to facilitate learning. However, the majority of speech act research to date has been conducted using data from online learning platforms such as Learning Management Systems (LMS) or Microsoft Teams. Therefore, this study aims to investigate the occurrence of illocutionary speech acts used by lecturers in the Statistics for Language Research course. Descriptive qualitative research was employed in this study to analyze data obtained from the speech characteristics in messages posted in the Statistics for Language Research (SLR) course on the LMS and conversations between the lecturer and students recorded on Microsoft Teams. Data analysis was conducted based on the speech acts theory from Searle (1969). The study's findings showed that the courses employed four different illocutionary speech patterns. The study's findings revealed that the courses utilized four distinct illocutionary speech patterns. The most frequent occurrences were noted in assertive, expressive, directive, and commissive speech acts. From the data, it is evident that assertive speech acts are the dominant type. Furthermore, commissive speech acts were involved in the LMS, primarily focusing on scheduling plans for class. To conclude, it is implied that the recordings highlighted assertive speech acts as the dominant type, which was mainly utilized for explaining materials to students.

The load growth in recent times due to advancements in technology and population increase has led to shortage of reactive power in the power system resulting in key issues such as voltage instability, large line losses, power outages among others. In this work, Particle Swarm Optimization (PSO) technique was used for optimal placement of Unified Power Flow Controller (UPFC) for power loss minimization using the IEEE 6-bus system as a test network. The load flow analysis was performed using Gauss-Seidel iterative method with and without inclusion of PSO-based UPFC. The PSO algorithm was used to find the optimum point for UPFC location and determined using the line with the least active power loss among other lines randomly selected by the PSO algorithm, with p.u defined as the voltage statutory limit. The simulation results revealed that the optimum point obtained was line 4-5, and the voltage profile were within the statutory limit with and without optimally placed UPFC. The total active power loss reduced from 495.5 to 273.9 MW, giving a reduction of 44.72 with optimally placed UPFC. The total reactive power loss equally reduced from 1439 to 936.2 MVAr, producing a reduction of 34.94 with optimally placed UPFC. These results obtained showed that PSO-based UPFC placement is suitable for power loss minimization and enhancement of the system voltage profile.

Advancements in blood group typing techniques are pivotal in improving blood bank operations and patient care. These techniques, spanning serological and molecular methods, have revolutionized transfusion medicine. Serological typings reliability, using hemagglutination reactions against specific antisera, remains key for blood compatibility assessment. However, time constraints and limited rare variant detection have driven molecular methods evolution, such as PCR and DNA sequencing. These offer accuracy, rapidity, and rare variant identification. Such innovations have overhauled blood bank operations, enabling effective transfusion matching, reducing reactions, and enhancing outcomes. They have streamlined donor screening, optimized rare type use, and eased organ transplant compatibility testing. Despite challenges like cost and standardization, advancements in point-of-care devices, AI algorithms, and personalized medicine promise further enhancements. These advances ensure safer, efficient blood transfusion practices.
A CoQ10 terápiás-, prevenciós- és sportteljesítményre vonatkozó bizonyított hatásai

Published: June 2024

Egyre több bizonyíték utal arra, hogy a szervezet CoQ10-szintje több klinikai kórképpel és a sportteljesítménnyel is összefüggésbe hozható. Szakirodalmi áttekintésünk készítése közben számost tanulmányt találtuk, amelyek alapján a CoQ10 a gyulladásos mediátorok és oxidatív stressz csökkentésével olyan betegségekre lehet jótékony hatással, mint a szív- és érrendszeri-, vagy daganatos megbetegedések, a cukorbetegség, illetve különböző neurológiai kórképek. Emellett a petesejtek mitokondriális energiaellátásának fokozásával, és a sperma paramétereinek javításával szerepe lehet a meddőség kezelésében is. Kulcs szerepet játszik a sportteljesítmény alakulásában, mivel csökkenti az izomkárosodás mértékét és a fáradást jelző paramétereket (CK), késlelteti a kifáradást, gyorsítja a regenerációt, valamint javítja a máj- és vesefunkciókat. Az áttekintésben szereplő publikációk nagy részének gyengesége, hogy alacsony esetszámúak, valamint egyes esetekben ellentmondásos eredmények születtek. Érdemes lenne magasabb esetszámú kutatásokkal mélyrehatóbb elemzéseket, illetve a sporttáplálkozás területén sportágspecifikus vizsgálatokat végezni, mely lehetővé tenné hivatalos, evidence-based étrend-kiegészítési protokollok kidolgozását táplálkozástudományi szakemberek számára.

Az aktív részvétel, az életminőség javításának központi célja miatt az egészség, a kaland- és sportturizmus szorosan összefonódik. Jelen kutatás az életkor és a sportmotiváció közötti összefüggéseket vizsgálja a szabadtéri vízi sportturizmus kontextusában. Kérdőíves felmérésünkben (n=282) a Sportmotivációs Skálát alkalmaztuk a belső, a külső sportmotiváció és az amotiváció mérésére a szabadtéri vízi sportok gyakorlóinak körében, az eredményeket statisztikai módszerekkel elemeztük ki. Eredményeink azt mutatják, hogy az életkor előrehaladtával szignifikánsan csökken mindhárom belső motiváció-típus szintje, míg az amotiváció szintje az életkor előrehaladtával növekszik. Ez azt jelenti, hogy a fiatalabb korosztályoknál jelentősebb az élvezetkeresésre, a fejlődésre való törekvésre és a tudás megszerzésére irányuló belső motiváció, míg az idősebbek kevésbé kitartóak a nehézségekkel való megküzdésben a szabadidős tevékenységek gyakorlása során. A külső motiváció típusokban nem találtunk az életkorhoz kapcsolódó tendenciákat. Eredményeink felhívják a figyelmet az életkorbeli különbségek vizsgálatának fontosságára az aktív turizmus és a szabadidősport területén.
From more sustainable isocyanide-based multicomponent reactions to spiro-heterocyclic compound syntheses
Authors:   , Salami Sodeeq Aderotimi
Published: June 2024

The global pharmaceutical industry has undergone profound transformations in the past two decades in the search for new drugs. For this reason, most pharmaceutical companies made significant investments not only in the development of new drugs but new methodologies. Modern drug development is confronted with the challenge of developing chemical reactions that are highly capable of providing most of the elements of structural complexity and diversity with the fewest possible synthetic steps for the specific target with the most intriguing properties. The discovery of more sustainable, environmentally friendly reactions capable of forming multiple bonds in a single step has been a challenge in organic synthesis over the years. Many organic chemists have recently started focusing on creative ways of reducing environmental pollution. The use of hazardous solvents has been reduced or eliminated in research to limit harm to both people and the environment. The pursuit of this goal has drawn many organic chemists to the study of various sustainable synthetic techniques including catalysis, aqueous organic reactions and mechanochemistry. The scope of this thesis was to apply sustainable techniques to design multicomponent synthetic protocols for the Passerini reaction and further apply these new protocols to construct spiro-heterocyclic compounds, all based on green chemistry principles. There is a need to develop rapid, efficient, and versatile strategies for the synthesis of bioactive molecules via multicomponent reactions. This project tried to avoid some of the pitfalls of traditional approaches, such as toxicity, low yield, long reaction times, harsh conditions, experimental complexity, and limited functionalization scope. This was achieved by focussing on the use of isonitriles and isothiocyanates as key reactive intermediates, and making extensive use of aqueous reaction conditions, mechanochemistry and microwave activation.

Nature-based solutions (NbS) are globally implemented to address a wide variety of water management challenges. While extensive research on NbS has been conducted in the Global North, developing countries have received less attention. There is a lack of information about the NbS that can be applied in the Andean region and their potential to address water challenges and provide ecosystem services. This article aims to bridge this gap by performing a review of the emerging literature on NbS in the context of Andean countries. A comprehensive analysis of 38 publications was conducted, with a focus on strategies for addressing water-related challenges. Our findings reveal that there has been an increase in NbS publications in the Andean region in recent years. A higher prevalence of empirical studies was observed in gray literature. In addition, we identified 26 potential NbS, including ancestral practices, to address water challenges. The main challenges that Andean countries seek to solve through these NbS are water scarcity, flood risks, and water quality. This research highlights the significance of assessing the efficiency of NbS initiatives and disseminating this knowledge to discover more opportunities for implementation in the Andean region.

Neste estudo, parte-se do entendimento que o pátio escolar ao ar livre, enquanto espaço/tempo de interação das crianças pequenas com os elementos da natureza, contribui para a aprendizagem e desenvolvimento infantil. O presente artigo tem como objetivo apresentar as descobertas emergentes do trabalho de campo com as crianças do Pré A de uma Escola Municipal de Ensino Fundamental localizada no Rio Grande do Sul (Brasil) a fim de discutir as relações envolvendo as crianças e o pátio escolar no contexto da Educação Infantil. Fundamentada em uma base teórica interdisciplinar e alinhada com a perspectiva vygotskyana da teoria sociocultural-histórica do desenvolvimento, a pesquisa visou mapear o que os pré-escolares apreciavam (ou não apreciavam) nos ambientes internos e externos de sua Escola de Educação Infantil para brincar e interagir, bem como apreender os significados, valores e afetividade expressos em suas vivências espaciais. A metodologia da pesquisa envolveu uma observação participante, utilizando um dispositivo de jogo da memória para mediar a interação com as crianças. As análises revelam que (a) o pátio externo constitui um território-lugar para as crianças, dada a multiplicidade de significados, valores e afetividades que emergiram de suas brincadeiras neste ambiente; (b) as crianças compartilham significados, valores e afetividades que se diferenciam do entendimento dos adultos; (c) as restrições espaço-temporais determinadas pelos adultos relacionadas com o acesso das crianças aos ambientes limitam o livre brincar delas.

Entrepreneurship has established itself as a growing career option for women. In this sense, the objective of this study was to analyze how life stories interfere with supportive female entrepreneurship, in the municipality of Rio Grande located in the State of Rio Grande do Sul. This analysis aims to understand the challenges that women in a supportive group, have to undertake throughout their history. This is a qualitative, descriptive research, in which data collection was carried out through face-to-face interviews, maintaining the necessary protocols due to the Covid-19 pandemic. The main results found from the women's life stories portray: lack of money to start production, difficulty in moving around, insecurity due to fear of not working out, lack of suitable place to work, search for income to support the family and for financial independence, especially independence from the spouse. Still regarding the challenges, the lack of balance between work and personal life of these women stands out, which causes exhaustion and health problems. As considerations, there are the positive points perceived throughout the journey in the solidarity enterprise: the equal relationship between the interviewees, recognition for their work, expansion of the relationship network and unconditional support from the cooperative.

The water quality in Awang Bay, West Nusa Tenggara, Indonesia, is considered to be polluted due to human activities. This research aims to evaluate the water quality in Teluk Awang based on the physicochemical properties of water and zooplankton as bioindicators. Sampling was conducted at three beach locations: Awang, Ujung Kelor, and Ekas. The physicochemical water quality parameters measured included water temperature, pH, dissolved oxygen (DO), salinity, and transparency. Additionally, environmental factors were observed based on the naturalness and hemeroby index. The result of the identification and counting of the abundance of each zooplankton can then be used to analyze including taxa richness, total density, the diversity index of Shannon-Wiener (HSW), Margalef diversity index, Simpson diversity index, evenness index (E), and dominance index (C). The resulting research indicated that the physicochemical water qualities have met government quality standards for marine biota needs, except for the level of transparency at Ekas Station 3. Ekas Beach has the highest level of transparency, diversity, taxa richness, and total abundance of zooplankton, indicating the best water quality. Ujung Kelor Beach, which has the highest level of naturalness and the highest DO concentration, has moderate zooplankton diversity, indicating that the water quality is in the medium category. Meanwhile, Awang Beach, which had the highest human activity and the worst water quality, was characterized by low levels of transparency and DO, low diversity, taxa richness, and an abundance of zooplankton. Therefore, diversity, taxa richness, and abundance of zooplankton can be used as a bioindicator for changes in water quality.

Published: June 2024

Bridges are basic infrastructure that must be met to create regional connectivity in Indonesia. One type of bridge that is often used is a curved bridge, which has the advantages of high strength, attractiveness, aesthetics and economy. In order to accelerate the development of bridge infrastructure, an efficient innovation in curved bridge design is needed. The development of curved bridge structures to achieve efficient designs has received much attention in several decades. However, researchers have only focused on optimising the geometry variation of the arch height. Therefore, the aim of this research is to innovate the optimisation of the hanger spacing on the arch bridge structure. In order to obtain optimal results, a bridge model is carried out by varying the hanger spacing of the centre model with a hanger spacing ratio of (1.3 - 1.1 - 0.9 - 0.7), a flat model with a hanger spacing ratio of (1 - 1 - 1 - 1) and an edge model with a hanger spacing ratio of (0.7 - 0.9 - 1.1 - 1.3), so that from the three models, the effect of hanger location on three conditions is obtained. Each model is modelled in the SAP2000 software and given a bridge service load to obtain the internal forces and deflections that occur. The output of the internal force and deflection is then analysed to determine the effect of the location of the bridge service hanger. The serviceability of the bridge is also analysed by calculating the ratio between the weight of the bridge and the deflection that occurs. The results of the analysis show that the location of the hanger affects the performance of the arch bridge structure. The centre model bridge design produces the most efficient structural performance in resisting the compressive axial forces and moments that occur, and produces the least deflection. Meanwhile, the edge model will provide the most efficient structural performance in resisting tensile axial forces.  By referring to the results of the bridge weight to deflection ratio analysis, it can be concluded that the centre model produces the most efficient structural design when compared to other curved bridge models.

In Ancient period, Indian followed the organic farming cultivation, which led them to live long & healthy life. From 1960’s Indian are more dependent on conventional foods and their nutrition level is too low. Moreover, the change in the pattern of food consumptions of people appears to be one of the biggest threats to leading a healthy life. The problem of the study is people are already living in the place which is polluted in all means – air, water and land and in-addition to that the food which they intake is also polluted with fertilizer, pesticides, etc., Increase in usage of fertilizers and chemicals disintegrations the environment and human being’s health. In this Pandemic of COVID 19 worldwide teach us more on being hail &healthy. Now people are more aware about their health, so they are starting to shift to consuming organic foods. As a result of organic farming started booming in many countries. Organic is the term which is used frequently now-a-days by the consumers all over the world. This study is based on conceptual model. This research paper is an attempt to explain the organic food preference, Environmental consciousness, willing to pay, availability of organic food products etc.,
