Published: October 2024

Enhanced Oil Recovery termasuk ke dalam metode pengangkatan minyak tertiary, yang bertujuan untuk memperbaiki efisiensi pendesakan dan penyapuan volumetrik. Pendekatan EOR sendiri bertujuan untuk mendorong perolehan minyak menggunakan energi dari luar reservoir. Karakteristik minyak, batuan, dan air formasi memainkan peran penting dalam menentukan efektivitas metode EOR. Injeksi surfaktan tergolong menjadi salah satu teknik dalam Enhanced Oil Recovery pada reservoir dengan kandungan fluida dengan viskositas tinggi karena pengaplikasiaanya mampu menurunkan interfacial tension dan recovery yang dihasilkan relatif besar saat penyapuan pada minyak berat dibandingkan dengan injeksi air konvensional. Tween 20 sebagai salah satu surfaktan sintetik mampu tetap stabil pada salinitas dan suhu yang rendah. Tujuan dari penelitian ini adalah untuk mengetahui kekompatibilitasan surfaktan dengan minyak ringan dalam salinitas 8000 ppm dan suhu 60?C. Uji kompatibilitas meliputi dua pengujian, yaitu uji kestabilan larutan (aqueous stability) dan uji kelakuan fasa (phase behavior). Maka didapat hasil dari uji aqueous stability, yaitu semua konsentrasi larutan surfaktan Tween 20 memiliki fasa homogen yang menunjukan pada pengujian ini semua konsentrasi larutan kompatibel. Kemudian dilakukan pengujian phase behavior dan mendapatkan hasil pada larutan surfaktan tween 20 dengan konsentrasi 1% didapat emulsi fasa tengah sebesar 22,5%. Maka kesimpulan yang didapat dari penelitian ini adalah larutan surfaktan Tween 20 dengan konsentrasi 1% dianggap kompatibel dengan minyak ringan (39? API). Larutan Surfaktan Tween 20 dengan konsentrasi 1% memiliki kestabilan emulsi yang paling baik sehingga berpotensi besar untuk menurunkan interfacial tension agar dapat meningkatkan perolehan minyak.

Published: October 2024

This paper presents a comparative analysis of geochronological, geochemical, Sr-Nd isotopic data and geodynamic conditions for the Devonian magmatism of the East European Platform, using as an example the Pripyat-Dnieper-Donets rift zone in the south of the platform and the Kola alkaline province in the north.The Late Paleozoic rifting in the south of the platform was accompanied by magmatism, which formed a wide range of rocks, from alkaline-ultramafic lamprophyres and orangeites, non-diamondiferous kimberlites and carbonatites to typical tholeiites, trachyandesites, and trachyrhyodacites. Activation of rifting processes in the north of the platform has also produced a compositional diversity of magmatic occurrences dominated by kimberlites, in particular diamondiferous (Arkhangelsk diamond-bearing province), which is the main distinctive feature of the place. The Pripyat-Dnieper-Donets rift zone is subject to reverse lateral geochemical zonality of the mantle sources – from those depleted in the axial zone of the Dnieper-Donets trough to more enriched in the marginal parts – trough shoulders (Azov region, Voronezh crystalline massif): along the southeast to northwest axis of the rift zone to the Zhlobin saddle (orangeites, alkaline picrites of the Zhlobin alkaline-ultramafic complex) and in the Pripyat trough (Pripyat alkaline and subalkaline mafic complex) as well was perpendicular to the axis from the central part of the Dnieper-Donets trough to the southwest towards the Eastern Azov region (non-diamondiferous kimberlites) and to the northeast towards the Voronezh crystalline massif.Currently available petrological-mineralogical and isotopic-geochemical data on magmatites of both large magmatic structures suggest significant lithospheric heterogeneity, different types of sources of formation of rocks, and a significant influence exerted by the crustal component both in the southern and northern parts of the East European platform.

Published: October 2024

The dynamics of the convergence of telematics law within the national legal system, notably in the area of land, are represented by the Minister of Agrarian Affairs and Spatial Planning's Regulation Number 5 of 2020, which also serves as the head of the National Land Agency. One of the effects of land digitization is the Ministerial Regulation, which has changed the mortgage rights registration process from a traditional system to an electronic or digital one. Despite being virtual, the digitalization of Mortgage Rights registration involves actual legal actions with clear legal ramifications. The Land Deed Official is directly involved in the electronic execution of Mortgage Rights, which is governed by the Regulation of the Minister of Agrarian Affairs and Spatial Planning / Head of the National Land Agency number 5 of 2020. The objective of this study is to investigate the consequences of the convergence of the Law on Mortgage Rights and the Telecommunication Law. This convergence results in the creation of digital-based Mortgage Rights via an integrated Electronic Mortgage Registration system, which is also known as the Electronic Mortgage System. The role and obligations of the Land Deed Official are also affected by this. This study employs a prescriptive, normative-juridical methodology. Based on the research findings, it is known that the conversion of the collateral registration system from a traditional system to a digital system is affected by the convergence of telematics legislation and the law of collateral guarantees. Because of the discord and breakdown of the Mortgage Law, the Electronic Information and Transactions Law, and the Regulations of the Land Deed Official, this also affects the status and legal obligations of the Land Deed Official, who fails to maintain the principle of justice..

Published: October 2024

The Organic Inorganic Lead Iodide perovskite material has emerged as a pioneer in being an active material for third-generation solar cells. Apart from the synthesis, the scalable mechanism which is being used for the deposition process, greatly influences the performance of the cell owing to its impact on the morphology, uniform thickness, and interface between two functional layers. This study briefly discusses the various deposition processes involved in assembling the layers of perovskite solar cells (PSC). Hole transport materials (HTM) are a crucial part of the PSC providing efficient transport of the charge carriers. However, the effect of organic and inorganic HTMs is highly pronounced in the PSCs. This study also discusses the effect of organic and inorganic HTM on the stability and efficiency of the sandwich-structured PSC.
Performance Evaluation of a Mechanically-aided Cocoon Deflosser
Authors: Macadaeg Fatima 
Published: October 2024

Sericulture products such as woven linen and novelty items were already sold at the market at premium-priced commodities. However, it was not given emphasis and sustainable support. One of the problems identified is the availability of cocoon silk production machinery and equipment. Humans can defloss 2 to 3 kg or 900 to 1,600 pieces of cocoon in an hour. Therefore, cocoon delfossing is a tiresome laborious job. This contributes to the market's poor production of silk and novelty items. Hence, a cocoon deflossing machine with a higher deflossing capacity than a manual is needed. To address this concern, a mechanically aided cocoon deflossing machine was designed, fabricated, and evaluated. Performance evaluation of the machine shows that it lessens deflossing cost from USD 0.53 /kg manual deflossing to USD 0.47/kg. It has a capacity of 4.80 kg/hr and 2,374 pieces of cocoons per hour.

Published: October 2024

Examinations play a critical role in the education sector in assessing learners' knowledge and skill mastery. Therefore, they must be credible and free of irregularities. However, over the years, Kenya has seen an increase in examination malpractice. This has compelled the Kenya National Examination Council to devise some solutions to these problems. Despite the strict measures in place, several cases of KCSE examination irregularities every year are usually reported. This demonstrates that none of the existing measures have been able to eliminate examination malpractices, particularly in secondary schools in Nairobi County. This study investigated the impact of learning resource availability on the management of KCSE examination irregularities in Nairobi County, Kenya. The study population included all 99 secondary schools in Nairobi County, of which 80 were chosen. The descriptive survey design was used. The principal, dean of students, student leaders, and the county director of education were the units of observation. Data was gathered using an interview guide and questionnaires. The instruments were pre-tested to ensure their content, construct validity, and reliability. Data were analyzed by computing descriptive and inferential statistics using SPSS. The study discovered a positive link between the availability and the management of KCSE irregularities. The study, therefore, concluded that adequate learning resources such as laboratory equipment, instructional or teaching aids, textbooks, revision books, a well-equipped school library, and spacious classrooms were very helpful in the management of examination irregularities. It recommended that sufficient funds be committed to developing school infrastructure, facilities, equipment, and learning resources and that the government, through the ministry of education, disburse adequate funds and material resources. The findings provide new insight on how to address examination irregularities.

Published: October 2024

Background: Cytochrome P450(CYP1A2) has a crucial role in drug metabolism, and some neurotoxins. Polymorphisms of Cytochrome P450(CYP1A2) have a role in cancer activity through affecting aromatic hydrocarbon metabolism. This work was aimed at studying CYP1A2 polymorphism as a genetic predictive marker of treatment out come in breast cancer (BC) female cases.
Methods: This case control research included 70 cases. Patients’ group (50 cases) were categorized into two groups: Group I A (n=20): failed BC cases for hormonal therapy during treatment period, group I B (n=30): after 5 years of hormonal treatment which subdivided into two groups: [treatment failure (recurrence or metastasis) and patients with successful outcome] and group II (n=20): normal female subjects.
Results: The occurrence of treatment events was significant in patients carrying Polymorphism of Cytochrome P450(CYP1A2) (CYP1A2 rs762551) C/A. Also, relapse was earlier in patients with CYP1A2 carrying C allele and earlier among CC compared to C/A and wild allele. There was significantly higher in positive family history than in negative ones, with about 85.0% of positive family patients carrying C/A polymorphism and 77.8% in CC polymorphism. The incidence of BC events was studied using Kaplan-Meier scale to study event free survival in relation to CYP1A2 rs 762551 in postmenopausal BC patients treated with AI along five years treatment.
Conclusions: CYP1A2 genetic polymorphism is associated with early treatment events among female cases developing BC treated by aromatase inhibitors.
A Dynamical Explanation of the Topographically Bound Easterly Low‐Level Jet Surrounding Antarctica

Published: November 2017

AbstractThis study investigates the topographically bound easterly low‐level jet surrounding Antarctica. This jet is modeled as a balanced flow that satisfies the potential vorticity invertibility principle, based on local linear balance in spherical coordinates and expressed in isentropic coordinates. In this way, this easterly low‐level jet is shown to be the balanced flow associated with the topography of the Antarctic plateau, moderated by a shallow potential vorticity anomaly atop the plateau produced by radiative cooling. The dynamical connection of the jet with katabatic winds can be understood through the meridional circulation equation. Model results based on the simple theoretical arguments developed here are found to be consistent with high‐resolution reanalysis data from the European Centre for Medium‐Range Weather Forecasts for the 2008–2010 period.

AbstractThe relative greenness and wetness of Giant Sequoia (Sequoiadendron giganteum) groves and the surrounding Sierra Nevada, California forests were investigated using patterns in vegetation indices from Landsat imagery for the period 1985–2015. Vegetation greenness (normalized difference vegetation index) and thus forest biomass in groves increased by about 6% over that 30 year period, suggesting a 10% increase in evapotranspiration. No significant change in the surrounding nongrove forest was observed. In this period, local temperature measurements showed an increase of about 2.2°C. The wetness of groves (normalized difference wetness index) showed no overall long‐term trend but responded to changes in annual water‐year precipitation and temperature. The long‐term trends of grove greenness and wetness varied by elevation, with the lower rain‐snow transition elevation zone (1,700–2,100 m) marking a change from an increasing trend at lower elevations to a decreasing trend at higher elevations. The 2011–2015 drought brought an unprecedented drop in grove wetness, over 5 times the 1985–2010 standard deviation, and wetness in SEGI groves dropped 50% more than in nongrove areas. Overall, the wetness and greenness of SEGI groves showed a larger response to the warming climate and drought than nongrove areas. The influence of droughts on the wetness of SEGI groves reflected effects of both the multidecadal increase in forest biomass and the effects of warmer drought‐year temperatures on the evaporative demand of current grove vegetation, plus sufficient regolith water storage of rain and snowmelt to sustain that vegetation through seasonal and multiyear dry periods.

Published: November 2017

AbstractRemotely sensed microwave observations of vegetation optical depth (VOD) have been widely used for examining vegetation responses to climate. Nevertheless, the relative impacts of phenological changes in leaf biomass and water stress on VOD have not been explicitly disentangled. In particular, determining whether leaf water potential (ψL) affects VOD may allow these data sets as a constraint for plant hydraulic models. Here we test the sensitivity of VOD to variations in ψL and present a conceptual framework that relates VOD to ψL and total biomass including leaves, whose dynamics are measured through leaf area index, and woody components. We used measurements of ψL from three sites across the US—a mixed deciduous forests in Indiana and Missouri and a piñon‐juniper woodland in New Mexico—to validate the conceptual model. The temporal dynamics of X‐band VOD were similar to those of the VOD signal estimated from the new conceptual model with observed ψL (R2 = 0.6–0.8). At the global scale, accounting for a combination of biomass and estimated ψL (based on satellite surface soil moisture data) increased correlations with VOD by ~ 15% and 30% compared to biomass and water potential, respectively. In wetter regions with denser and taller canopy heights, VOD has a higher correlation with leaf area index than with water stress and vice versa in drier regions. Our results demonstrate that variations in both phenology and ψL must be considered to accurately interpret the dynamics of VOD observations for ecological applications.
