Published: March 2024

The Philippine educational system established alternative delivery modes of education, such as the Modified Work and Study Program, to eradicate student dropout incidence. This phenomenological study aims to probe the challenges and explore the coping mechanism of MWSP students in studying mathematics. The study was conducted at a public high school offering the program. Six students were chosen to participate in the study. Focus group discussion was utilized for the data gathering of the study. Results showed that mediocrity of resources and conspicuous learning environment were the leading challenges that MWSP students encounter. Moreover, the coping mechanisms include good classroom management, utilization of concrete examples, time scheduling, steward support, motivational encouragement, and recreational and body relaxation. It is recommended that MWSP mathematics teachers integrate innovative strategies, provide more concrete contextualized examples, intensify the development of learning kits, and reinforce teaching and learning through supplementary materials.

“HUMAN EXCEPTIONALISM”: THE GREEK ORIGINS OF A MODERN CONCEPTAND ITS IMPLICATIONS FOR THE LIVES OF ANIMALS
Authors: T. NEWMYER STEPHEN
Published: March 2024

The modern philosophical doctrine usually termed “human exceptionalism,” which holds that human beings, because of their perceived intellectual superiority over other animal species, have a moral value that cannot be claimed by other species which entitles humans to use other animals to serve their needs, has its philosophical roots in Greek philosophy, especially in the works of Aristotle and in the Stoic doctrine of oikeiōsis, which holds that human beings share a kinship with other humans but not with other species of inferior intellectual endowments. The doctrine of “human exceptionalism” is used in the twenty-first century to justify the wholesale slaughter worldwide of non-human animals for food, clothing, medical and entertainment purposes. The claims of “human exceptionalism” are countered in the present day by animal rights philosophers and by animal welfarists of various types who argue either that non-human species have a sufficient degree of reason to entitle them to inclusion in the sphere of human moral concern, or that the possession of reason is itself an irrelevant criterion for moral consideration, and that animal suffering must be taken into account in human interactions with other animal species.
HEGEL I MNEMOSINA: PROBLEM ZAJEDNIČKOG PAMĆENJA
Authors: ATANASKOVIĆ LAZAR
Published: March 2024

Ovaj rad bavi se mestima u kojima Hegel koristi metaforičku figuru Mnemosine kojom označava kompleksni karakter zajedničkog pamćenja. U Hegelovom opusu postoje tri značajna mesta na kojima se ova metafora koristi na sličan način, a kojima se ovaj rad podrobnije bavi: 1) Poglavlje o predstavi u Predavanjima iz filozofije subjektivnog duha (1827/28), 2) Odeljak o epici iz Fenomenologije duha (1807), 3) Uvodi za Predavanja iz filozofije svetske istorije (1822/23, 1828/29, 1830/31). Na osnovu čitanja navedenih odeljaka može se zaključiti kako Hegel koristi metaforu Mnemosine kako bi opisao delatnost putem koje nastaje pamćenje zajednice kroz dinamiku posredovanja između pounutrašnjivanja (Erinnerung) predstava i njihovog ospoljavanja u objektima zajedničkog pamćenja (Gedächtnis). Razumevanje ove dinamike od odlučujućeg je značaja za Hegelovo razumevanje istoriografije kao prakse zajedničkog pamćenja, kao i za mapiranje odnosa koji postoje između različitih praksi kojima biva artikulisano pamćenje zajednice.
„MEŠANI USTAV“ I SVETSKO-ISTORIJSKI REŽIMI U HEGELOVOJ POLITIČKOJ FILOZOFIJI
Authors: HRISTOV ĐORĐE
Published: March 2024

U ovom radu želim da pokažem da se Hegelova politička filozofija i posebno njegovo shvatanje organizacije ustava moderne države iz Filozofije prava poziva na njegovu hronologiju svetske istorije. Kako ću takođe pokazati ova veza se zasniva na njegovom preuzimanju ustava Rimske republike kako je on prikazan u delu starogrčkog istoričara Polibija. U prvom koraku ću se osvrnuti na Hegelovo preuzimanje Polibijevog modela „mešanog ustava“ i način na koji on putem ovog modela integriše svetsko-istorijske režime unutar svoje političke filozofije. Zatim ću ukazati na bitne razlike koje se javljaju između antičkog, republikanskog i modernog, monarhijskog ustava. Ove razlike se prvenstveno tiču odnosa rada i rata sa sferom politike i način na koji Hegel pokušava da „odloži“ pad suvereniteta moderne države. Na kraju ću se iz ovoga osvrnuti na ambivalentnost značenja „kraja istorije“ u njegovoj filozofiji.

Najduže ću se zadržati na nekim pitanjima koja su pokrenuta povodom naše teme u savremenoj filozofiji: razmotriću klasifikacije granica na telesne i bestelesne, prirodne i veštačke, odnosno bona fide i fiat granice, na jasne i nejasne ili mutne. Ukazaću takođe na neke probleme vezane za pitanja razgraničenja i granica susednih entiteta. Na kraju ću reći nešto i o pitanju granica samih granica.
MIMEZIS JE NEGDE DRUGDE I: PRISTUPANJE MIMETIČKOM KRAJOLIKU DRŽAVE
Authors: TATALOVIĆ NIKOLA
Published: March 2024

Tekst nastoji da se izbori za pristup Platonovom pitanju o mimezisu nastojeći da odgovarajući metod pronađe u samom tekstu Države. Prvi deo rada predstavlja razmatranje pitanja zašto se pitanje mimezisa u poslednjoj knjizi Države ponavlja, tj. zašto se mimetički pesnik vraća u Sokratov govor ako je prethodno bio uspešno izgnan? Otvarajući mogućnost da mimetički pesnik zapravo nikada nije bio proteran, već da je sve vreme bio skriven unutar samog Sokratovog govora, članak u drugom svom delu ukazuje na to da Platon unutar prve kritike mimezisa, razlikom sadržaja i stila podražavanja, nudi ključ za čitanje njegove kritike mimezisa, ali celine Države. Rečju, rad predlaže način čitanja Platona koji bi predstavljao primenu Platonovog metoda intepretacije podražavajućeg pesnika na dato tumačenje. Rad naznačava da dati pristup otvara uvid u Platonovu neprestanu igru onoga šta i onoga kako, učenja i načina na koji ono biva izgrađeno. Data igra, kao sudar šta sa kako, otvara uvid u bitno rapsodijski karakter Platonove kritike mimezisa.
Rekayasa Rekayasa Legalitas Akad Mukhabarah dalam Sistem Paroan Perspektif Fiqih Muamalah di Desa Karangnangka Kabupaten Sumenep Madura
Authors: Andi Ardiyan Mustakim  , Abdul Khoir
Published: March 2024

Tradisi paroan yang berlangsung pada masyarakat desa Karangnangka kabupaten Sumenep Madura telah berjalan bertahun-tahun. Tradisi paroan yaitu kerjasama antara pemilik tanah dan pengelola tanah untuk mengolah tanah dengan bercocok tanam yang semuanya ditanggung oleh pengelola tanah dan hasilnya dibagi berdasarkan kesepakatan. Permasalahan muncul ketika tidak ada kesepakatan bagi hasil diawal transaksi. Pada akhirnya ketika pembagian hasil panen, pemilik lahan merasa tidak puas sebab bagiannya sedikit. Penelitian ini berusaha menjawab permasalahan tersebut dengan metode kualitatif yang bersifat deskriptif normatif analisis. Teori yang digunakan adalah teori akad mukhabarah dan rekayasa legalitas (hilah) sebagai jawaban atas permasalahan. Hasil penelitian adalah Pertama, akad mukhabarah yang digunakan tidak sah sebab adanya ketidakpastian dan ketidakjelasan pembagian hasil panen (garar). Kedua, akad mukhabarah yang batal beralih status menjadi akad ijarah berdasarkan rekayasa legalitas (hilah). Ketiga, hasil panen sepenuhnya milik pengelola tanah dan bagi pemilik tanah upah standar. Maka transaksi tersebut walaupun batal tapi pemilik tanah dapat mengajukan negoisasi bagi hasil panen dan bagi pengelola tanah harus memberikan bagian pemilik tanah sesuai kesepakatan. Jika tidak terjadi kesepakatan maka pemilik tanah dapat mengajukan tuntutan ke pengadilan. (The paroan tradition that has taken place in the Karangnangka village community, Sumenep Madura Regency, has been going on for years. The paroan tradition is a collaboration between the land owner and the land manager to cultivate the land with cultivation, all of which are borne by the land manager and the results are shared based on an agreement. Problems arise when there is no profit sharing agreement at the beginning of the transaction. In the end, when dividing the harvest, the land owner was dissatisfied because his share was small. This study attempts to answer these problems with a qualitative method that is descriptive normative analysis. The theory used is the theory of mukhabarah contracts and legality engineering (hilah) as an answer to problems. The results of the study are First, the mukhabarah contract used is invalid because of pressure and unclear distribution of harvest (garar). Second, the mukhabarah contract which was canceled changed its status to an ijarah contract based on engineering legality (hilah). Third, the harvest fully belongs to the land manager and the standard wage for the land owner. So, even though the transaction is canceled, the land owner can submit a negotiation for harvest sharing and the land manager must give the land owner's share according to the agreement. If there is no agreement, the land owner can file a lawsuit in court.)
Promotion of Intellectual Activity Results of Scientific Organizations. Regulatory Framework and Statistics
Authors: Ganieva Irina , Shepelev Gennady
Published: March 2024

We consider intellectual activity results (IAR) of scientific organizations in the context of intellectual property protection and as one of the indicators of their effectiveness. The data characterizing Russia’s place in the world rankings in terms of the number of patent applications and the number of applications per 1 million people are presented, and a conclusion is made about the relatively low activity in protecting IAR in comparison with the leaders of the ratings. The authors have conducted an analysis of normative legal acts (NLA) on the consolidation and transfer of rights to IAR, as well as NLA that characterize IAR in terms of the effectiveness of research activity, as well as of the certification of researchers. It is concluded that the current system of NLA does not impede or discourage the work of scientific organizations with IAR. It is shown that NLA related to the evaluation of the effectiveness of scientific institutions should also stimulate their active work with IAR. At the same time, the available statistical data on the share of research organizations in patent applications filed and licenses sold indicate that their activity in promoting IAR in the real sector of the economy is on average more than twice lower than in Russia as a whole. It is assumed that the evolving situation regarding working with IAR is determined by economic factors. We have outlined ways for further research on factors that can significantly affect the activity of scientific organizations in working with the promotion of IAR, in particular, to assess the potential demand for IAR and the prospective value of IAR from the points of view of the seller and the buyer.

Published: March 2024

This research aims to analyze product innovation in village administration services through the Banyuwangi Smart Kampung application. This application adds alternative service products at the village level where previously there were other service products, namely village smart websites and self-service platform machines. The presence of the application brings changes to the public service process in Banyuwangi. Previously, services could only be accessed offline or by coming to the village office. Meanwhile, by using the application, the service can be accessed online. In its implementation in the community, there are still several obstacles, starting from the system, which still frequently experiences errors, as well as obstacles from the Banyuwangi community, many of whom don't know about the existence of this application. This research aims to describe the development of Banyuwangi Smart Kampung application service products. This research uses a descriptive qualitative research method using a phenomenological approach. The data analysis technique used is an interactive model data analysis technique. The results of this research show that the Banyuwangi Smart Kampung application can be enjoyed directly by the community because this application makes it very easy for the community to access a service. In implementing the application in society, the government has played an active role in monitoring the implementation of the application by making improvements and updates. The quality of the service product in the form of this application is better than the previous product because, in terms of features and usability, this application is quite complex, namely not only for services at the village level, but can also access services at the district level and can be used for other public services besides administration services. Previously, there was no service product that had the same features and uses as the Banyuwangi Smart Kampung application.

A expansão artificial do litoral e a destruição dos ambientes de costa rochosa na região metropolitana do Rio de Janeiro
Authors: Faria Antonio Paulo
Published: March 2024

A partir de meados do Século 19 as alterações causadas na geomorfologia do litoral do Rio de Janeiro, Niterói e São Gonçalo foram intensas, afetando, inclusive, os ambientes de costa rochosa. Relevos rochosos na costa foram destruídos ou desfigurados para extrair sedimentos e fragmentos de rocha para construir muros, casas, edifícios, pontes, portos, ruas e rodovias. A expansão das áreas urbanas desses municípios com aterros avançou consideravelmente sobre o litoral da Baía de Guanabara e sobre a costa oceânica. Encostas de montanhas, morros e ilhas que abrigavam ecossistemas marinhos, foram destruídas, ou passaram a ser ambientes urbanos. Mensurações no campo e nas imagens do Google Earth indicam que foram destruídos 45,7 km lineares de ambientes naturais de costa rochosa, incluindo: 16,8 km de campos marinhos de blocos e clusters marinhos de blocos; 8,9 km de pequenas baías rochosas, costa retilínea e convexa, com perfis de costão e falésia; e pequenas ilhas rochosas com perímetro total de 18 km. Esses ambientes rochosos naturais foram substituídos por estruturas artificiais, ou tecnoformas, que retificaram o litoral. A construção de estaleiros, portos e marinas criou costa dentada e baías com estruturas de concreto. Do total de 95 km lineares de estruturas construídas, 26,2 km são enrocamentos que servem de contenção para aterros, guia-correntes e quebra-mares. Muros e alicerces para viadutos e edifícios totalizam 68,5 km. Essas formas antropogênicas tendem a ser menos resistentes aos eventos naturais extremos que as tipologias geomorfológicas naturais, e devem ter alterado os padrões de circulação das correntes marinhas e o transporte de sedimentos. Falta ainda saber como essa substituição influencia as espécies marinhas bentônicas.

Численное моделирование течения газа в затурбинном диффузоре на переменных режимах с верификацией по эксперименту
Authors: Cherkasova M G , Chernikov Vladimir Antonovich , Semakina Elena Yur'evna
Published: March 2024

Как правило, при проектировании газотурбинных установок (ГТУ) рассматривается номинальный режим работы. На этом режиме стараются выдержать осевой выход потока из турбины для уменьшения потерь с выходной скоростью. Осевой вход в диффузор является оптимальным, так как в таком случае отсутствуют углы атаки на обтекателях силовых стоек, которые являются неотъемлемой частью диффузора, где располагается задняя подшипниковая опора ротора турбины. Тем не менее в ходе эксплуатации ГТУ установка длительно работает как на номинальном, так и на переменных режимах. Переменные режимы характеризуются значительными углами атаки на обтекателях силовых стоек, что приводит к отрыву потока и значительному увеличению потерь давления в диффузоре. Возникает вопрос в обеспечении удовлетворительного течения в диффузоре на режимах с переменной нагрузкой при сохранении оптимальной работы ГТУ на номинальном режиме. В настоящей работе экспериментальным и численным методами исследованы особенности течения в диффузоре в широком диапазоне нагрузки. Исследования показали, что при углах выхода потока из последней ступени менее 50$^\circ$ течение в диффузоре приобретает несимметричный характер с развитыми вихрями. Это приводит к тому, что численное моделирование в инженерной постановке не может повторить характер течения. Тем не менее сравнение полных параметров эксперимента и расчeта показывает хорошее совпадение (разница около 5%) даже для режимов с большими углами атаки на обтекателях стоек диффузора.

Published: March 2024

Osmanlı İmparatorluğu’nun tarihî seyri içerisinde önemli dönemlerden biri, XVI. yüzyılın son çeyreğine denk gelen “Uzun Savaşlar Dönemi” dir. Bu dönemde Osmanlı İmparatorluğu, Avrupa’daki en büyük rakibiyle karşı karşıya gelmiş ve Macaristan sahası için üstünlük mücadelesi vermiştir. Bu dönemdeki en kritik savaşlardan biri Sultan III. Mehmed’in liderliğinde gerçekleştirilen Eğri Seferi’dir. Eğri Kalesi, Osmanlı tarihinde ilk kez 1552 yılında Vezir Ahmed Paşa’nın komutasındaki ordu tarafından muhasara altına alınmış ancak fethedilememiştir. Kale, bu andan itibaren sıkı bir yenilenme süreci geçirmiş ve İtalyan tarzında modernize edilmiştir. Bu bakımdan Sultan III. Mehmed ve kurmayları 1596 yılı baharında çıktıkları Batı Seferi’nde Eğri’yi hedef seçmiştir. Habsburg cephesinin Osmanlıların hangi yönde ilerleyeceklerini kestirememesi Eğri kalesinin savunulması için gerekli hazırlıkların gecikmesine sebep olmuş ve kalede ciddi bir savunma zafiyeti oluşmuştur. Osmanlı ordusu, 20 Eylül 1596 tarihinde Sultan III. Mehmed önderliğinde kaleyi muhasara altına almış, Osmanlıların sayı ve teknik üstünlükle sürdürdüğü üç haftalık mücadele sonucunda kale 12 Ekim 1596 tarihinde Osmanlıların eline geçmiştir. Bu andan itibaren bölgede Eğri merkezli bir beylerbeylik kurulmuştur. Bu çalışmada, Sultan III. Mehmed’in Eğri Seferi doğrultusunda, seferin nedenleri, hazırlıkları, seyri ve sonuçları gibi konular detaylı bir şekilde ele alınacaktır. Ayrıca, seferin Osmanlı İmparatorluğu’nun genel stratejisi üzerindeki etkisi ve Osmanlı-Avusturya ilişkilerine olan yansımaları da değerlendirilecektir.

Water production management is a common concern for oil fields adopting water flooding. Water shut-off (WSO) technologies: both mechanical and chemical methods have been investigated to mitigate increasing water production. Mechanical methods like cementing or shut-off by completion types work within the wellbore. Crosslink polymer gels as chemical method penetrate by maximum 10 ft from the wellbore in most cases. Hence, the crossflow inside the reservoir is considered as a potential risk to deteriorate the WSO impact on production improvement. This paper focuses on an advanced nano-chemical WSO technology, which is emulsion system with supercharged nanoparticles (ESN®). The ESN® has unique features to overcome several difficulties which conventional chemical methods face frequently. Furthermore, the ESN® has a strong advantage that can selectively block water zone and penetrate in maximum 50 ft from the wellbore.

A pilot test of chemical water shut off using ESN® is planned in an offshore carbonate oil field (Field-A) in Abu Dhabi. The Field-A has been developed under continuous water injection more than 25 years and suffers from the resultant high water production. Well-1 was selected as a candidate well for pilot test because this well had been unable to flow due to high water cut.

As the first step of pilot preparation, the effectiveness of ESN® was evaluated using the numerical simulation model compared with conventional WSO methods. In the simulation model, local grid refinement (LGR) was applied at the grids including wellbore to replicate the penetration feature of each WSO. According to this model, the ESN® expected significant benefit on the well life extension by water cut reduction and increase in oil production compared with the conventional gels.

For further detailed evaluation by the numerical model, the uncertainty of reservoir properties affecting crossflow was evaluated through sensitivity study. In the upper part of reservoir in the Field-A, there is high permeability streak which acts as a main flow path for injected water from injectors to producers. For vertical and deviated oil producers, the perforation was conducted below the high permeability streak to avoid early water breakthrough. With consideration of these specifications, a sensitivity study of vertical permeability and high permeability streak was conducted. As a result of sensitivity study, improvement of well performance by ESN® was expected with consideration of parameter uncertainty range, though incremental oil production is dependent on parameter value.

As the next step of pilot preparation, this sensitivity study outcomes were also utilized to select such pilot well which can expect maximum incremental recovery by applying this technology.

The economic model, grounded in the balanced waterflood flow approach, determines the optimal injection volumes and the associated number of oil-producing and water-injecting wells.

Analyzing production data is complex, relying on numerous diagnostic metrics such as reserve properties analysis, reservoir energy diagnostics and watercut/GOR diagnostics, productivity measures, and economic factors. This analysis facilitates rapid modeling of future performance and forecasts economic outcomes in response to redevelopment investments.

Automation has revolutionized modern production analysis, enabling the generation of comprehensive diagnostic metrics with a simple "mouse click"—a process that typically spans months. Newly developed diagnostic metrics improve upon traditional production/injection performance analysis, especially those based on automatically generated numerical 3D micro-models that simulate expected rock/fluid properties.

Well interference is assessed through mathematical algorithms for multiwell deconvolution, utilizing extensive bottomhole pressure and surface rate data. This deconvolution, either fully or semi-automated, searches for initial pressure and unit-rate transient responses in tested and adjacent wells, aligning them with actual pressure records and aggregate flow rates.

Further advancements include the automated analysis of these diagnostic metrics, supported by AI-based digital tools that offer economic insights for enhancing production.

The case study in Western Siberia identifies deposits and wells where not all proven recoverable reserves are being tapped. It advocates for side-tracking from current wells and implementing multi-stage fracking to activate these reserves and sustain pressure. The economic model generated by this study proposes investment scenarios with a profitability index (PI) of 1.4, an attractive prospect considering the reserves’ current maturity.

The application of deconvolution in cross-well pressure interference analysis has fine-tuned production and water injection targets, yielding a 6% uplift in field oil production without the need for well interventions.

This paper presents a couple of examples of waterflooding efficiency assessment and a ranked list of investment opportunities to unlock field potential. Integrating open-hole data with meticulous well-by-well production analysis, we pinpoint prospective drilling sites. Advanced production analysis notably accelerates the analysis process, thereby diminishing the risk of overlooking enhancement opportunities.

Objective/Scope

Increase in water-cuts is a common occurrence in oil fields in which water flooding is used for secondary oil recovery. Managing cost of water handling is one of the primary challenges as it continues to erode the profitability. Furthermore, increasing energy requirements to reinject or dispose of the water leads to additional carbon dioxide emissions. More efficient processes are needed to reduce CAPEX & OPEX and reduce carbon emissions.

Methods, Procedures, Process

In anticipation of water rates exceeding facility produced water deoiling capacity, Saudi Aramco upgraded an existing gravity water-oil separator with a hybrid process that combines enhanced gravity separation and induced gas flotation (IGF) in one vessel. The feed water enters a gravity section with plate packs as a primary deoiling process. Water with less oil from the gravity separator then feeds an IGF system within the same vessel to reduce the oil-in-water even further. Deoiled water is then degassed in a quiescent section before being discharged to the injection pumps.

Results, Observations, Conclusions

Deoiling capacity was implemented at 40% of the cost of a conventional processes. After the retrofit, the deoiling capacity increased by 50% and the outlet oil-in-water was reduced by 65%. Significant capital expenditure savings were realized as it eliminated the need to install additional vessels for increasing gravity separation capacity. Furthermore, it eliminated the need for installing a separate induced gas flotation system. Additionally, stable water flow from the separator resulted in reducing energy consumption by 15% as the downstream water injection pumps do not need to recycle due to dips in feed flow caused by severe fluctuations in rate. Energy savings reduces costs and carbon emissions. Improved water quality means more oil is recovered which translates to additional revenue. Some lessons learned were gained, including adjustments to start-up procedures and the ideal control setup to ensure a smooth and stable process.

Novel Information

The hybrid solution process can achieve the desired capacity and water quality with less footprint and enhanced process control. The project offers several design and operations best practice of this hybrid system. Since it has been commissioned in July 2022, Saudi Aramco has both increased capacity and quality of the water. Furthermore, water flow to the injection rate has been more energy efficient due to less recycling.
Gas Treatment Produced Water Reuse

Industrial produced wastewater management has been a challenging objective in the Oil and Gas Industry, and the adoption of systems to reuse it is essential to promote the circular economy principles. Saudi Aramco, adapted an integrated system to collect, treat, and reuse the facility-wide produced water to eliminate directing it to evaporation ponds, or outside the facility to waste management entities. Produced water, in gas plants, is usually formed in three processes: separating wells’ sour water from monoethyl-glycol, knocking out sour water during gas sweetening, and during acid gas handling and cooling. The produced water is instantly directed to sour water treatment to remove the hydrogen sulfide, and finally to a biological wastewater treatment plant. The wastewater treatment plant's objective is to reducing the total organic compound (TOC) content in the water through bacterial activity, and filtration. Once the TOC is minimized to the process requirement, it is reused within the plant as a cooling tower make-up water.

It is both an environmental and an economical driven adoption. Produced wastewater is reused to reduce plant's purchased water quantity significantly, and it ultimately leads to minimize the facility's purchased fresh water quantity especially during the summer season where the evaporation rate is high. Also, this leads to a reduction of CO2 footprint as a result of avoided purchased water desalination (scope 2 carbon emission). This initiative also supports the circular economy principles by conserving the plant's water, and minimizing the demand on fresh products.

Published: March 2024

As the oil and gas industry continues to evolve, advanced analytical tools have become a critical component in improving field withdrawal and injection performance. This paper showcases the effectiveness of the Simplified Capacitance Resistance Model as an analytical tool in optimizing an inverted nine-spot injection pattern in a large carbonate oil field with over 100 producers and water injectors. Additionally, the paper explores how these methods can improve the overall efficiency of pattern waterflooding in the field.

The overall approach integrates the simplified CRM to balance withdrawal and injection patterns. Initially, basic surveillance data is used to optimize production and withdrawal surveillance. To incorporate connectivity understanding between injectors and producers, Simplified CRM output is added as additional parameters in the inverted nine-spot pattern to optimize production strategy.

The integrated approach presented in this paper has resulted in optimized injection and withdrawal across injection patterns, assisting to regulate field production for long-term sustainability. For each injector surrounded with a minimum of 8 producers, this approach governs the withdrawal and drawdown from each producer to ensure consistent oil sweep within the patterns. In addition, it also acts as an optimization tool to cater for any production balancing required by the production facilities, improving response time to mitigate production setback and realizing production requirement. The approach effectively incorporates a large amount of surveillance data into a systematic work process, providing clear output and optimization production strategy.

This paper presents an alternative approach to utilize the simplified CRM as an analytical tool for pattern balancing in a large carbonate oil field. The use of simplified CRM to optimize production and withdrawal surveillance adds to the state of knowledge in the petroleum industry. It will benefit readers facing similar scenarios and field configurations.

With the increase in ethnocultural diversity in the Canadian demographic landscape, it is imperative for healthcare providers and policy makers to understand the needs and preferences of racialized immigrant older adults. Previous research has shown that to increase patient satisfaction with care and lower treatment costs it is important to effectively involve patients in their care. However, we currently lack the understanding of how racialized immigrant older adults want to engage as patients, the factors that influence their involvement in their own care, and who they want involved in the decisions surrounding their care. To address this gap in the literature specifically for the South Asian community, one of Canada’s largest and fastest growing populations, our study aimed to understand South Asian older adults’ experiences with and approaches to patient engagement and shared decision-making. We conducted in-depth individual and dyadic interviews (n=28) in six languages, utilizing a multilingual cross-cultural qualitative approach. Our findings highlight the nuances of language and how miscommunication can arise even when patients and providers are conversing in the same language. Our study also found that patient engagement and shared decision-making, including the desire for family involvement, is heavily influenced by both culture and gender. Additionally, perceptions of patients regarding the status of physicians can have a notable influence on patient engagement, leading to an increased tendency for patients to agree with the physicians’ approach to care. These findings suggest that effective engagement between providers and patients require a tailored approach that extends beyond white-centric approaches to decision-making and communication.

Objective: This study aims to fill this gap by evaluating the safety, tolerability, and adherence of patients prescribed Paxlovid® in outpatient settings, focusing on its use in managing category 2 COVID-19 patients across three primary healthcare clinics in Selangor, Malaysia.
Design: Retrospective cross-sectional study
Setting: Data were collected from the Paxlovid® pharmacy registry and medical records at Klinik Kesihatan Seksyen 7, Klinik Kesihatan Seksyen 19, and Klinik Kesihatan Kelana Jaya between April 1, 2022, and November 30, 2022.
Participants: This study analysed data from 415 category 2 COVID-19 patients aged ≥18 years old.
Primary and secondary outcomes: Parameters assessed included patient demographics, dosing, current medication, changes in drug regimen, adherence, and ADR. Pharmacists follow-ups were conducted on days 3 and 5 post-medication initiation.
Results: The majority (79.5%) of the cohort experienced ADR, predominantly dysgeusia, diarrhoea, body ache, vomiting, and nausea. Despite these, the ADR were generally well-tolerated, with no severe impacts reported. High adherence was observed, with 96.9% of patients completing the 5-day regimen. The primary reasons for non-adherence included adverse effect intolerability, dosing ambiguity, forgetfulness, concerns about ADR, and perceived health improvement. Notable medications interacting with Paxlovid® were simvastatin, amlodipine, and atorvastatin, and 21.7% of 23 concurrent medications were found not complying to the recommended interventions by the University of Liverpool COVID-19 Drug Interaction database.
Conclusion: Nirmatrelvir-ritonavir (Paxlovid®) demonstrates a high level of safety and tolerability in outpatient COVID-19 patients, with optimal adherence observed. This study underscores the vital role of healthcare professionals in managing Paxlovid® within primary healthcare and highlights the need for broader research and direct patient involvement to enhance treatment strategies against COVID-19.

This study investigates the compressive behavior of functionally graded gyroid lattice structures fabricated from AlSi10Mg using selective laser sintering. Through systematic variation of design parameters such as relative density, cell size, uniform wall thickness, and gradient of wall thickness, the research examines how these factors affect mechanical stability and collapse mechanisms under load. Compression testing provides insights into strength, deformation, and failure modes of the structures, offering valuable contributions to the understanding of their compressive strength. The findings have significant implications for applications requiring lightweight yet robust structures, particularly in aerospace, automotive, and other engineering disciplines, thereby advancing the field of metal additive manufacturing and its potential in advanced structural designs.
Unlocking the Prospective of Neglected and Underutilized Wild Plants for Human Food, Nutrition and Ethno-Medicine
Authors: Abuka Mihretu , Feyissa Getachew Sime
Published: March 2024

Wild edible plant species (WEPs) are vital sources of additional food and ethnomedicine in many regions of the world. Despite the fact that they can offer a range of provisioning services, they are neglected, underutilized, and poorly researched. This study therefore investigated WEPs and their provisioning ecosystem services as supplementary food, nutrition, and traditional medicine. Questionnaire household surveys, key informant interviews, and a series of field observations were used for data collection. Additionally, preference ranking was used to rank the WEPs based on the preference of the local communities for their provision of services. A direct matrix ranking was carried out to measure their provisional service diversity. There were 20 WEPs species, which were most widely used as food, nutrition, and ethnomedicine supplements. The major edible plant parts were fruits (75%), which were mostly collected by children (65%). The majority of the communities (93.95%) used them as seasonal and supplemental food, particularly in periods of food shortages such as spring, the dry season. They were particularly essential supplementary sources of food, nutrition, and ethno-medicine for food-insecure and economically marginal families. It is therefore necessary to develop national policies that support and encourage WEPs as dietary, nutritional, and ethno-medical supplements.
