Each contract is allowed to include a clause regarding contract extension, when the contract ends. The clause in the contract is that even though both parties have reached an agreement, the extension of the contract is not an obligation or achievement in the contract, for this reason if the construction and handover cooperation contract has ended and the service recipient hands over management to the government as the service user , refusing a request to extend the contract cannot be said to be a breach of promise or default. However, even though refusing to extend the construction and handover cooperation contract is the right of the service user, there needs to be a review if the contract period which is supposed to be long-term only stipulates a period of 7 (seven) years if it results in the contractor or pemodal as the service recipient being harmed.

Authors: Talakua Eddy
Published: February 2024

Minyak bumi merupakan bahan bakar yang banyak digunakan oleh masyarakat seperti bahan bakar untuk kendaraan bermotor yang tersedia di SPBU milik Pertamina serta yang dijual oleh perorangan, antara lain : Pertalite, Pertamax, Pertamax turbo. Bahan bakar tersebut menjadi pilihan utama konsumen di Indonesia berdasarkan data Biro Pusat Statistik (BPS, 2015). Meningkatnya jumlah kendaraan bermotor menyebabkan  semakin meningkatnya permintaan bahan bakar tersebut. Saat ini semakin maraknya masalah yang terjadi yaitu banyaknya Stasiun Pengisian Bahan Bakar Umum (SPBU) yang ditutup dikarenakan rendahnya kualitas kemurnian bahan bakar, serta semakin meningkatnya penjualan bahan bakar kendaraan secara per-orangan dalam bentuk Mini Pom Bensin. Hal tersebut memicu meningkatnya kecurangan dalam bentuk memanipulasi standart konsentasi bahan bakar yang diizinkan. Kondisi ini sangat merugikan masyarakat sebagai konsumen. Bahan bakar kendaraan yang tidak berstandart juga mengakibatkan meningkatnya kadar polusi udara karena pembakaran yang tidak sempurna (Pemanasan global, Aripin, 2009). Oleh karena itu diperlukan suatu alat yang dapat mendeteksi jenis dan kualitas bahan bakar kendaraan bermotor supaya masalah yang terjadi diatas dapat di minimalisir. Atas dasar pemikiran tersebut maka kami merancang suatu alat yang dapat mendeteksi jenis bahan bakar kendaraan bermotor, dengan judul : “IMPLEMENTASI SENSOR GAS UNTUK DETEKSI JENIS BAHAN BAKAR KENDARAAN BERMOTOR MENGGUNAKAN METODE FUZZY MAMDANI ”.

Teatralità e cangianze Turchesche
Authors: Bellingeri Giampiero
Published: February 2024

This essay collects a sort of concise anthology of excerpts concerning aspects of Ottoman culture frequently compared, or contrasted, with Persian culture, considered on the one hand ‘noble’ – when compared to the closer and more threatening, and therefore ‘ignoble’, ‘Turks’ –, on the other hand considered as potential ally of the Serenissima, capable of attacking the menacing Ottomans from the East. These human landscapes are brought to life by the theatricality and rhetoric of artistic representations emerging from the changing cultural scope of those ‘ferocious infidels’, enemies of Christianity, gradually becoming generous and noble bearers of the ‘Turchesca’ (or ‘Turkish’) culture.

The Advancement of Western Epistemology in Islamic Education
Authors: Rozali M. , Lubis Nurul Syahrani
Published: February 2024

This article examines the development of Western Epistemology in the World of Islamic Education. The findings in this paper explain that: There are two conflicting methods in achieving knowledge, namely rational and empirical methods. Both are biased methods in Western epistemology. In fact, in real terms, both methods play an equal role in discovering knowledge. Therefore, science is now more empirical in nature, placing greater emphasis on experience, observation and research/experimental plus Descartes' ways of thinking. This combination of reason and empirical is called the scientific method. This method developed rapidly and colored Western or general epistemology.

Because this study greatly contributes to political problems in Indonesia such as corruption and social injustice which are often debated. The aim of this article is to understand 3 things: First, the political paradigm of Ali bin Abi Talib's time. Second, internal and external factors that influenced the politics of Ali bin Abi Talib's time. Third, the positive and negative implications of politics for Muslims at that time. The method used is qualitative research with a literature review approach. The results found were 3 things: First, the political paradigm of Ali bin Abi Talib's time had 3 forms: (1) war politics (2) peace (3) justice. Second, internally there were 3 factors that influenced it: (1) differences of opinion (2) Caliph Ali's policies (3) Caliph Ali's characteristics. Externally, there are 5 factors that influence it: (1) the death of Muslims (2) support from the Kuffah community (3) the Governor's negligence (4) community problems (5) selfishness. Third, there are 3 positive implications for Muslims: (1) making it easier for Caliph Ali (2) the emergence of different forms of Islamic law (3) an orderly government system. Meanwhile, the negative implications for Muslims are 3 things: (1) changes in the Islamic government system (2) the emergence of new groups (3) division of Muslims.

An Analysis of Political Ethics from the Perspective of Muhammad Arkoun
Authors: Surianto Annisa Pratiwi , Junaidi Junaidi
Published: February 2024

This study is grounded in the profound need to comprehend the role of Mohammed Arkoun, a postmodern/contemporary scholar, in revitalizing the potential of Islamic thought in the 21st century. The article underscores Arkoun's significance as an Islamic philosopher who successfully integrates the "authenticity of Islam" with a broad understanding of contemporary social sciences, giving rise to the concept of Applied Islamology. With a life background immersed in two traditions, Islam (Algeria) and France (the West), Arkoun endeavors to reconcile various aspects of life from both civilizations.The research methodology employs descriptive, historical, comparative, and synthetic analysis approaches. Data collection involves extensive literature research on Arkoun's works, both his writings and relevant contributions from other authors. Based on a philosophical-critical examination of the data, it is concluded that Arkoun plays a significant role in shaping an inclusive study of Islam for the future. The findings offer profound insights into Arkoun's contribution to connecting and harmonizing Islamic thought with contemporary social sciences.

Published: February 2024

Synthetic substances like many pharmaceuticals, preservatives or other chemical compounds are actually very difficult to handle in sewage treatment. These compounds are very stable in aqueous solution and their degradation reactions are insufficient. Therefore, to eliminate these substances from wastewater additional afford is necessary. Extreme conditions like pH value, redox potential, chemical or physical energy need to be present. With our study we try to show that the use of plasma discharge could be a solution to this problem. Using the example of methylparaben, a preservative, we could show, that the physical energy of plasma discharge is able to initialize the degradation reaction in aqueous environment. The concentration was reduced by up to 70 percent in our setting depending on the treatment duration. Overall, the system showed potential to optimize wastewater treatment. Further examinations are necessary for example regarding undesirable by-products. Keywords: wastewater treatment, plasma discharge, high voltage, degradation
Algorithm for Control of Traffic Flow in an Intelligent Transport System
Authors: Yankevich Natallia
Published: February 2024

Traffic management in modern Intelligent Transport Systems (ITS) includes monitoring the actual traffic situation in real time and management transport traffic using this information. At the same time, cars as ITS components must be equipped with communication capabilities for exchanging information with other vehicles (V2V) and road infrastructure (V2I). Such approach is connected with usage of special equipment connected to on-board network for local data collection, which can be exchanged between cars and with a central communication station using wireless Internet. At the same time, the issue of developing the traffic organization algorithms themselves is still open. This problem can be solved with the help of game theory, a fairly new but rapidly developing part of modern mathematics. Unlike optimization theory, which studies the possibilities of constructing an optimal solution for the entire system as a whole, game theory studies ways to optimize individual benefits in competition with other persons (events) that rationally seek to satisfy their own benefits. The problem of "smart" regulation of intersections is quite difficult to solve a problem, nevertheless it is possible due to rapid development of ICT technologies.

“Russian Emigres in Volynia during the Reign of Ivan IV”
Authors: Halperin Charles J.
Published: February 2024

In this superb monograph, based upon monumental archival and manuscript research, Konstantin Erusalimskii explores the lives and cultural contributions of Muscovite emigres during the reign of Ivan IV to Volynia, part of the Grand Duchy of Lithuania and then the Kingdom of Poland. Through case studies of the most prominent emigres, above all Prince Andrei Kurbskii, Erusalimskii examines their social consciousness and cultural contributions, both literary compositions and translation projects. The emigres did not think of themselves as traitors. They remained and were treated by indigenous subjects of Poland-Lithuania as outsiders, “Muscovites.” Among numerous original conclusions Erusalimskii argues that publicist Ivan Peresvetov and printer Ivan Fedorov were one and the sane man, introduces an original, signed letter in Polish from Kurbskii to Herzog Albrecht von Hohenzollern of Brandenburg, and portrays Kurbskii as a Renaissance historian.

The Potential for Fuel Reduction to Offset Climate Warming Impacts on Wildfire Intensity in California
Authors: Brown Patrick , Strenfel Scott , Bagley Richard , Clements Craig
Published: February 2024

Increasing fuel aridity due to climate warming has and will continue to increase wildfire danger in California. In addition to reducing global greenhouse gas emissions, one of the primary proposals for counteracting this increase in wildfire danger is a widespread expansion of hazardous fuel reductions. Here, we quantify the potential for fuel reduction to reduce wildfire intensity using empirical relationships derived from historical observations using a novel combination of spatiotemporal resolution (0.5km, hourly) and extent (48 million acres, 9 years). We use machine learning to quantify relationships between sixteen environmental conditions (including ten fuel characteristics and four temperature-affected aridity characteristics) and satellite-observed fire radiative power. We use the derived relationships to create fire intensity potential (FIP) maps of sixty historical weather snapshots at a 2km and hourly resolution. We then place these weather snapshots in differing background climatological temperature and fuel characteristic conditions to quantify their independent and combined influence on FIP. We find that in order to offset the effect of climate warming under the SSP2-4.5 emissions scenario, fuel reduction would need to be maintained perpetually on ~3 million acres (at a 5-year return frequency, 600,000 acres, or ~1% of our domain, per year) by 2050 and ~8 million acres (at a 5-year return frequency, 1.6 million acres, or ~3% of our domain, per year) by 2090. Overall, we find substantial potential for fuel reduction to negate the effects of climate warming and that whether or not fuel reduction is scaled up has larger leverage on our domain average FIP than shifting global greenhouse gas emissions from the SSP2-4.5 to the SSP1-2.6 trajectory.
How white people manage the weight of the past: The role of advantaged identity strategies in linking colonialism to current racial inequality
Authors: Cáceres Enzo , Kende Judit , Boiger Michael , Hickson Helena , Hitschfel Christin , Doosje Bertjan
Published: February 2024

Linking European colonial deeds to current racial inequalities may pose identity challenges to white European people. Using mixed-methods consisting of qualitative interviews (N = 24) and quantitative surveys (N = 591), we addressed the strategies that white people in the Netherlands use to manage their ethnic-racial identity in relation to linking colonialism with current racial inequalities. In doing so, we explored whether and how white people’s ethnic-racial identity strategies relate to legitimising ideologies of inequalities. We found that white Dutch people exhibited different combinations of prideful (high identification), dissociating (low identification), and power-cognisant (critical identification) identity strategies. Specifically, those holding prideful and dissociating strategies were less prone to link colonialism and racial inequalities than white people exclusively endorsing power-cognisance. Thereby, power-cognisant people challenged current racial inequalities the most. We conclude by discussing how uncovering ethnic-racial dominant groups’ identity strategies recasts prejudice as stemming from structures of inequality and facilitates person-centred interventions.
Social Psychology in the Task Organization of Dyadic 90° Rhythmic Coordination: The Coupling Is Not What You Might Expect
Authors: Zhu Qin , Wang Xiaoye Michael , Palmer Carly , Bingham Geoffrey P
Published: February 2024

Herth, Zhu and Bingham (2021) investigated frequency scaling of a learned 90° bimanual rhythmic coordination in the context of both noninterference and correcting instructions. They found that performance of 90° coordination remained stable at high frequencies with correcting, but that performance deteriorated as frequency increased without correcting. The participants trained during learning both at performing bimanual and unimanual coordination and in both cases, they trained to the same criterion level of performance. Herth, Zhu and Bingham (submitted) then tested these same participants with frequency scaling of unimanual 90° coordination. They found in this case that the stability of performance was lost in the same way both with and without correcting. The question raised by this difference in results was whether the inability to maintain stable performance of unimanual coordination with correcting was due to the lack of kinesthetic/neural coupling or to the lack of bidirectional coupling present in bimanual coordination. To separate the two differences in coupling, frequency scaling of learned 90° coordination between two people (dyads) was tested in the current study because this was expected to isolate bidirectional coupling without the kinesthetic/neural coupling. Dyadic coordination is strictly visual. However, the results were identical to those found with unimanual coordination. The ability to correct did not yield stable performance at high frequency. An analysis was performed that showed that the coupling in the dyadic coordination was unidirectional contrary to the common expectation. Dyads were not allowed to communicate directly during learning and testing sessions, but they established the role of the coordinator and corrector vs who would just be steady state in organizing the task performance, nevertheless. Some dyads never achieved criterion performance even after over a dozen training sessions. Perchance they failed to achieve the requisite task organization. The results yielded an interesting problem in social psychology.
Frequency scaling of unimanual 90° rhythmic coordination: Data and model
Authors: Herth Rachel A. , Zhu Qin , Bingham Geoffrey P
Published: February 2024

Two rhythmic coordinations, 0° and 180° relative phase, can be performed stably at preferred frequency (~1 Hz) without training. Evidence indicates that these behavioral modes entail detection of the relative direction of movement that is used as perceptual information to control and coordinate performance. At higher frequencies, this yields instability of 180° and spontaneous transition to 0°. The ability to perform a 90° coordination can be acquired by learning to detect and use relative position as information. Herth, Zhu and Bingham (2021) found that skilled performance of 90° bimanual coordination exhibits mode switching to 0° or 180° with frequency scaling. Unlike the switching from 180° to 0°, transition from a learned coordination to 0° or 180° entails a change in information. They found that neither this switching nor performance of corrections to resist switching entailed intentional decisions during performance. Relatedly, they found that correction is not intrinsic to skilled performance of 90°. They successfully simulated results of frequency scaling of 90° using an extended Bingham model in which switching and correction were initiated as the information for 90° fell below threshold. We now attempt to replicate these findings testing unimanual 90° coordination with noninterference and correcting instructions. With correcting in the previous study, bimanual 90° coordination remained stable at all frequencies while noninterference instructions yielded mode switching at higher frequencies. Snapp-Childs, Wilson and Bingham (2011) showed that unimanual coordination switches at much lower frequencies than bimanual coordination. It is significantly less stable due to coupling that is unidirectional. The current finding was that unimanual performance of 90° fails to remain stable even with correcting at higher frequencies. Results were simulated using a unimanual version of the extended Bingham model.
Explaining immigrant-native differences in health at birth: The role of immigrant selectivity in Spain
Authors: Ferrara Alessandro , Cozzani Marco
Published: February 2024

A vast literature finds that immigrants have better health than natives, despite being socio-economically disadvantaged – the so-called “Immigrant Health Paradox” (IHP). A key question is whether and how this advantage is passed on to their children, especially in Europe where the research is less developed and conclusive. Moreover, theoretical explanations for the IHP are rarely empirically verified. This includes the popular “selectivity hypothesis”, according to which immigrants are healthier because positively selected at origin in terms of health or socio-economic status (SES). Using 2007-2019 Spanish birth registries, we investigate immigrant-native gaps in health at birth (birth weight and gestational age) and whether they are explained by immigrants’ educational selectivity. We find that immigrants are less likely to deliver low birth weight (LBW) children, but are disadvantaged in terms of macrosomia and gestational age. Selectivity is associated with reduced LBW also net of parental SES, which explains the lower risk of LBW children among immigrants and especially those from Northern Africa and Latin America. Nevertheless, some groups have higher LBW risks despite being positively selected, and educational selectivity is not associated with macrosomia and gestational age. We confirm the selectivity hypothesis but question its universality across groups and health outcomes.
Divided minds: The effect of Brexit on implicit prejudice
Authors: Olsson Filip
Published: February 2024

This paper studies the impact of the Brexit referendum on prejudiced attitudes, focusing specifically on implicit prejudice. The study thereby tests the effect of Brexit on more unconscious, affective, and covert forms of prejudice. The paper utilizes a natural experiment methodology, comparing levels of prejudice right before and after the Brexit vote in the United Kingdom. The study finds no overall effect of Brexit on prejudice, but finds a significant and strong effect contingent on political identity: right-wing respondents became implicitly more prejudiced, and left-wing respondents became implicitly less prejudiced. There was no corresponding changes in explicit prejudice for any of the groups. The study concludes by discussing the result in light of previous research, but also how it underscores the importance of using implicit measures in addition to explicit measures when studying prejudiced attitudes.

This study examines the effect of monetary policy on macroeconomic variables such as gross domestic product, real interest rate, inflation, unemployment and balance of payment etc. All the variables are intertwined with each other, and one way or the other it affects each other in both short run and long run. It is secondary research with causal comparative research design. It has quantitative nature and time series data are extracted from year 1990 to 2017 of six different macro-economic variables for the study. Statistical tools and applied econometrics namely, descriptive statistics, ADF, Johansen cointegration test, Engle- Granger error correction model are applied. The result from the statistical analysis shows that instruments of monetary policy has influence on the selected macroeconomic variables to some extent and satisfies to be relatively effective. Findings of the study reveals that there is long-run relationship between monetary policy and the selected macroeconomic variables in the Nepalese economy significantly from the error correction mechanism.
Cost Benefit Analysis of Chaudhary Bakery Udhyog

Published: February 2024

The research aims to explore the cost analysis and cost-benefit analysis with the help of Net Present Value and Internal Rate of Return in Chaudhary Bakery Udhyog (CBU). The research attempted to show the relationship between cost and benefit of the Chaudhary Bakery Udhyog. It followed descriptive cum analytical research design. The present re­search work covered a time period of five years 2017 to 2021. The presentation and analysis of benefit (net profit), benefit cost ratio (BCR), net present value (NPV) and internal rate of return (IRR).

Benefit cost ratio (BCR) has been found greater than 1. Hence it can be concluded that this BCR greater than 1 may be due to the longer experience and good managerial ability. BCR is greater than 1 is represents the ratio of total benefits over total costs. It has been found that the bakery udhyog is running in profit. In the analysis NPV is greater than zero in every year. NPV is greater than zero is indicate that the total discounted value of benefit is greater than the total discounted value of costs. It is represent the udhyog performance is well. So, it is generating satisfactory profit in study period. The udhyog has a internal rate of return is 10.19%. It represents the discount rate at the NPV of Chaudhary Bakery Udhyog is equal to zero. It means present value of benefits equal to present value of costs of the udhyog. The IRR is greater than discount rate. It can be concluded that the udhyog is running well and performance is better.
Bio-pesticidal, Antimicrobial, and Anti-inflammatory Potentials of n-Hexane Fraction of Zanthoxylum armatum DC and its Chemical Profiling
Authors: Baral Janaki , Adhikari Achyut
Published: February 2024

Zanthoxylum armatum DC, commonly known as toothache tree, is utilized for treating inflamed gums. The plant’s volatile constituent possesses a robust fragrance and contributes to its tangy taste. This study investigates the bioactivities, including bio-pesticidal, antimicrobial, and anti-inflammatory properties as well as the chemical profiling of the n-hexane fraction based on GC-MS analysis. The evaluated activities involve contact toxicity, microplate alamar blue assay, against three different insects, five bacteria, and seven fungi, and oxidative burst assay. The NIST library serves as a standard reference database for constituent identification. Remarkable insecticidal activities comparable to the standard drug permethrin were observed, particularly against Rhyzopertha dominica (100%), Tribolium castaneum (60%), and Sitophilus oryzae (50%). The fraction exhibited significant antifungal activity against Fusarium lini (85%) and notable inhibition against B. subtillis (67.27%) and S. aureus (65.25%). Potent anti-inflammatory effects were noted with an IC50 value of 11.2±1.9 μg/ml, equivalent to standard ibuprofen at various concentrations. GC-MS analysis identified twenty compounds, with major ones including trans-13-octadecenoic acid (36.08%), cis-9 hexadecenoic acid (18.66%), and 2-propenoic acid 3 phenyl methyl ester (11.08%). The diverse bioactivities observed may be attributed to the varied nature of compounds such as polyunsaturated fatty acids and their oxides. This research revealed the potential of Z. armatum as a potential bio-pesticide, anti-inflammatory, and antimicrobial agent.

Plastic debris is one of the most significant organic pollutants in the aquatic environment. Researchers are currently focusing on the impact of micro and nano-scale plastic waste on aquatic systems. In this study, we investigated the distribution of plastic pellets and fragments present in the freshwater ecosystem. The goal was to assess microplastic (MP) abundance in the Hanumante River, a tributary of the Bagmati River, and analyze their properties. Sample collection involved the bottle sampling method. Filtration, wet peroxide oxidation, density separation, gravimetric analysis, and microscopic examination were performed to study the characteristics of microplastics. The study was conducted by following the guidelines of the National Oceanic and Atmospheric Administration (NOAA) protocol. Gravimetric analysis was applied to calculate the reduced mass of the sample after total organic carbon reduction. Results showed that the maximum amount of reduced sample was obtained from the sample taken from sample taken from Madhyapur Thimi area (~3.593g) and the minimum amount of reduced sample was obtained from the sample taken from the Shiva temple Jagati area (~2.130g).  Microscopic inspection showed that samples taken from different locations were composed of an average of 14–23 microplastics per liter of sample. FT-IR analysis was performed to analyze the characteristics of microplastics and the type of polymers present in the sample which showed the abundance of polymer materials like polyethylene, polypropylene, and polycarbonates. The findings imply that appropriate plastic waste management measures be implemented in the communities to safeguard the ecosystem benefits derived from the river.
