ISTERI SEBAGAI PENCARI NAFKAH UTAMA: Studi terhadap Perajin Kapuk di Desa Imogiri, Bantul, Yogyakarta
Authors: Djazimah Siti , Habudin Ihab 
Published: August 2017

Islam has expressly regulate the division of tasks and roles between husbands and wives fairly. Although the husband is obliged to provide sustenance for his wife and children, but the family law of Islam does not forbid a wife from helping her husband in making a living with her husband's consent and does not interfere with her obligations as a housewife. There is a wife in a family of craftsmen in the village of Tegal Kembang, Imogiri, Yogyakarta, which acts as the main breadwinners for their families. This article examines the wives who work as the wage earners by using the concept of maqa> s} id ash-shari'ah < 'ah. The impact that emerges of the role of the kapok craftsmen woman is more on the impacts that are in positive traits and it is associated with the hajjiy and daruriy needs. The wife who has an income has the economic independence power that can even sustain the needs of the family. Social interactions that occur in kapok craftsmen community, make a strong emotional connection between kapok craftsmen. While the social interaction with the "outside world" (consumers) clearly provides insight of the Kapok Craftsmen. As for the negative impact of the mother's role of Kapok craftsman towards parenting does not seem significant.[Islam secara tegas telah mengatur tentang pembagian tugas dan peran antara suami dan istri secara adil. Walaupun suami berkewajiban memberi nafkah kepada isteri dan anak-anaknya, tetapi hukum keluarga islam tidak melarang istri membantu suaminya dalam mencari nafkah dengan persetujuan suaminya dan tidak mengganggu kewajibannya sebagai seorang ibu rumah tangga. Ada istri pada keluarga perajin kapuk di dusun Tegal Kembang, Imogiri, Bantul, Yogyakarta, yang berperan sebagai pencari nafkah utama bagi keluarganya. Tulisan ini mengkaji para isteri yang bekerja sebagai pencari nafkah dengan menggunakan konsep maqa>s}id asy-syari<‘ah. Dampak yang ditimbulkan dari peran yang dijalankan para ibu perajin kapuk adalah lebih pada dampak yang sifatnya positif dan hal ini terkait dengan kebutuhan yang sifatnya daruriy dan hajjiy. Para isteri yang mempunya penghasilan tersebut memiliki kemandirian dalam ekonomi bahkan dapat menopang kebutuhan keluarga. Interaksi sosial yang terjadi dalam komuitas perajin kapuk, menjadikan kuatnya hubungan emosional di antara perajin kapuk. Sementara interaksi sosial dengan “dunia luar” (konsumen) jelas memberikan wawasan perajin kapuk semakin bertambah. Adapun dampak negatif peran ibu sebagai perajin kapuk terhadap pengasuhan anak tidak nampak secara signifikan.]
PANDANGAN MASYARAKAT TENTANG TAUKIL WALI: Studi di Desa Dempet Kabupaten Demak
Authors: Iftidah Ida 
Published: August 2017

Wali (Marriage Guardian) is one of the important element in marriage. The position of marriage guardian determines whether the marriage is legitimate or not, because marriage guardian is one of the pillars of marriage that must be met. But the majority of people in the village of Dempet Demak, delegate the rights to the ward headman or local religious leaders. As a result, the deed committed by the wali nasab, regarded as the legitimate action. That is, from the dempet village community perspective, the act of doing this is not a form of violation, However as the best solution for the guardians who have no ability to perform her own daughter marriage. This happens for several reasons such as the inability to say the pronunciation of the marriages contract, lack of knowledge of the guardian so that they delegate to people who know more about the religion, even some that because of ta'ẓim to Kiai. The Events of taukil wali in the village of Dempet normatively is permissible because that has brought benefits to our fellow human beings as of the presence of 'taukil wali' has helped facilitate the affairs of human beings and as a form of mutual help in goodness and piety. This paper describes the issues regarding 'taukil wali' of Islamic law and positive law.[Wali merupakan salah satu unsur penting dalam pernikahan. Posisi wali menentukan sah dan tidaknya pernikahan, sebab wali nikah adalah salah satu rukun nikah yang harus dipenuhi. Namun mayoritas masyarakat di Desa Dempet Kabupaten Demak, mewakilkan hak perwaliannya kepada penghulu atau tokoh agama setempat. Mereka tidak terbiasa menikahkan putrinya sendiri. Akibatnya perbuatan yang dilakukan wali nasab tersebut dianggap hal yang sah-sah saja. Artinya masyarakat Desa Dempet tidak melihat bahwa perbuatan yang dilakukannya itu sebagai sebuah bentuk pelanggaran, tetapi sebagai solusi terbaik bagi para wali yang tidak ada kemampuan untuk mencoba menikahkan anaknya sendiri. Hal ini terjadi karena beberapa alasan seperti ketidakmampuan wali mengucapkan lafal akad nikah, kurangnya pengetahuan wali sehingga mewakilkan kepada orang yang lebih paham tentang agama, bahkan ada juga yang karena ta’ẓim kepada Kiai. Peristiwa taukil wali di Desa Dempet secara normatif hukumnya adalah boleh, sebab yang dilakukan telah memberikan manfaat terhadap sesama manusia karena dengan adanya taukil wali nikah telah membantu memudahkan urusan sesama manusia dan sebagai bentuk tolong menolong dalam hal kebaikan dan ketakwaan. Tulisan ini mendeskripsikan tentang masalah taukil wali nikah secara hukum Islam dan hukum Positif.]

Este trabalho apresenta uma avaliação dos potenciais LDA, GGA-PBEsol, BJ, mBJ original, mBJ P-presente e mBJ P-semicondutor em cálculos dos band gaps dos semicondutores ZnO, GaN, TiO2 e SnO2 utilizando o formalismo da Teoria Funcional da Densidade (DFT). O objetivo de utilizar diferentes potenciais é avaliar qual destes descreve em acordo com o experimental tanto os valores quanto a natureza dos band gaps dos semicondutores. Nos cálculos das estruturas eletrônicas (estrutura de bandas), estes potenciais descreveram em pleno acordo com os experimentais a natureza direta → dos band gaps destes compostos. No entanto, o potencial mBJ P-semicondutor foi o único que descreveu em concordância com o experimental os valores dos gaps. Os valores calculados dos gaps com o potencial mBJ P-semicondutores foram de 3,37 eV (ZnO), 3,48 eV (GaN), 3,06 eV (TiO2) e 3,80 eV (SnO2), os quais concordam com valores experimentais.
Flavonoids – Small Molecules, High Hopes
Authors: Sandu Mariana , Bîrsă Lucian Mihail , Bahrin Lucian Gabriel 
Published: August 2017

Abstract
This brief review takes a look at flavonoids, a wide class of polyphenols, which are regarded as plant secondary metabolites. Their roles in plants are diverse and little understood. They can act as growth hormone modulators, phytoalexins, they offer UV protection, contribute to pollen viability and can function as signaling molecules in establishing symbiotic relationships. Flavonoids were also found to have a range of beneficial effects for the human body. Their anticancer, antioxidant, anti-inflammatory and cardioprotective activity, as well as their antibacterial, antiviral and antihelmintic properties make them promising candidates for the design of new drugs.

Authors: Abaszadeh Mehdi , Seifi Mohammad 
Published: August 2017

Abstract
KF/Al2O3 as a green and efficient catalyst has been used for synthesis of indolizine-1-carbonitrile derivatives. It can be proceeded by using 1,3-dipolar cycloaddition reaction of 1-alkyl-2-chloropyridinium bromides, malononitrile and benzaldehyde in ethanol, at reflux. The great advantage of this catalyst is the ease of handling. KF/Al2O3 can be used and removed by filtration, avoiding cumbersome aqueous workups and decreasing solvent waste handling issues. High conversions, short reaction times and a cleaner reaction profiles are some of the outstanding advantages of this method.

Published: August 2017

Abstract
The aim of the present study was to characterize the repair weld of serviced (aged) solid-solution Ni-Cr-Fe-Mo alloy: Hastelloy X. The repair welding of a gas turbine part was carried out using Gas Tungsten Arc Welding (GTAW), the same process as for new parts. Light microscopy, scanning electron microscopy, transmission electron microscopy, microhardness measurements were the techniques used to determine the post repair condition of the alloy. Compared to the solution state, an increased amount of M6C carbide was detected, but M23C6 carbides, sigma and mu phases were not. The aged condition corresponds to higher hardness, but without brittle regions that could initiate cracking.

Published: August 2017

Abstract
In this study, accuracies of genomic prediction across various scenarios were compared using single- trait and multiple-trait animal models to detect genotype × environment (G × E) interaction based on REML method. The simulated high and low linkage disequilibrium (HLD and LLD) genome consisted of 15,000 and 50,000 SNP chip applications with 300 and 600 QTLs controlling the trait of interest. The simulation was done to create the genetic correlations between the traits in 4 environments and heritabilities of the traits were 0.20, 0.25, 0.30 and 0.35 in environments 1, 2, 3 and 4, respectively. Two strategies were used to predict the accuracy of genomic selection for cows without phenotypes. In the first strategy, phenotypes for cows in three environments were kept as a training set and breeding values for all animals were estimated using three-trait model. In the second one, only 25, 50 or 75% of records in the fourth environment and all the records in the other three environments were used to predict GBV for non-phenotyped cows in the environment 4. For the first strategy, the highest accuracy of 0.695 was realized in scenario HLD with 600 QTL and 50K SNP chip for the fourth environment and the lowest accuracy of 0.495 was obtained in scenario LLD with 600QTL and 15K SNP chips for the first environment. Generally, the accuracy of prediction increased significantly (P<0.05) with increasing the number of markers, heritability and the genetic correlation between the traits, but no significant difference was observed between scenarios with 300 and 600 QTL. In comparison with models without G × E interaction, accuracies of the GBV for all environments increased when using multi-trait models. The results showed that the level of LD, number of animals in training set and genetic correlation across environments play important roles if G × E interaction exists. In conclusion, G × E interaction contributes to understanding variations of quantitative trait and increasing accuracy of genomic prediction. Therefore, the interaction should be taken into account in conducting selection in various environments or across different genotypes.
System effects of primary energy reduction connected with operation of the CHP plants
Authors: Ziębik Andrzej , Gładysz Paweł 
Published: August 2017

AbstractThe paper is devoted to explication of one of the advantages of heat and electricity cogeneration, rarely considered in technical literature. Usually attention is paid to the fact that heat losses of the heat distribution network are less severe in the case of cogeneration of heat in comparison with its separate production. But this conclusion is also true in other cases when the internal consumption of heat is significant. In this paper it has been proved in the case of two examples concerning trigeneration technology with an absorption chiller cooperating with a combined heat and power (CHP) plant and CHP plant integrated with amine post-combustion CO2processing unit. In both considered cases it might be said that thanks to cogeneration we have to do with less severe consequences of significant demand of heat for internal purposes.
On partial sorting in restricted rounds
Authors: Iványi Antal , Fogarasi Norbert 
Published: August 2017

Abstract
Let n and k be integers such that n ≥ 2 and 1 ≤ k ≤n. In this paper, we consider the problem of finding an ordered list of the k best players out of n participants by organizing a tournament of rounds of pairwise matches (comparisons). Assuming that (i) in each match there is a winner (no ties) (ii) the relative strength of the players is constant throughout the tournament and (iii) the players’ strengths are transitive, the problem is equivalent to partially sorting n different, comparable objects, allowing parallelization in rounds. The rounds are restricted as one player can only play one match in each round. We propose concrete pairing algorithms and make conjectures about their performance in terms of the worst case number of rounds and matches required. The research article was started by professor Antal Iványi who sadly passed away during the work and was completed in his honor by the co-author. He hopes, in this modest way, to reflect his deep admiration for professor Iványi’s many contributions to the theory, practice and appreciation of algorithm design and analysis.
Parallel ktjet clustering algorithm

Published: August 2017

AbstractThe numerical simulation allows to study the high energy particle physics. It plays important of role in the reconstruction and analyze of these experimental and theoretical researches. This requires a computer background with a large capacity. Jet physics is an intensively researched area, where the factorization process can be solved by algorithmic solutions. We studied parallelization of the ktcluster algorithms. This method allows to know the development of particles due to the collision of highenergy nucleus-nucleus. The Alice offline library contains the required modules to simulate the ALICE detector that is a dedicated Pb-Pb detector. Using this simulation we can generate input particles, that we can further analyzed by clustering them, reconstructing their jet structure. The FastJet toolkit is an efficient C++ implementation of the most widely used jet clustering algorithms, among them the ktclustering. Parallelizing the standard non-optimized version of this algorithm utilizing the available CPU architecture a 1:6 times faster runtime was achieved, paving the way to drastic performance increase using many-core architectures.
A unified approach of program verification
Authors: Gregorics Tibor , Borsi Zsolt 
Published: August 2017

Abstract
The subject of this paper is a program verification method that takes into account abortion caused by partial functions in program statements. In particular, boolean expressions of various statements will be investigated that are not well-defined. For example, a loop aborts if its execution begins in a state for which the loop condition is undefined. This work considers the program constructs of nondeterministic sequential programs and also deals with the synchronization statement of parallel programs introduced by Owicki and Gries [7]. The syntax of program constructs will be reviewed and their semantics will be formally defined in such a way that they suit the relational model of programming developed at Eőtvős Loránd University [3, 4]. This relational model defines the program as a set of its possible executions and also provides definition for other important programming notions like problem and solution. The proof rules of total correctness [2, 5, 8, 9, 7] will be extended by treating abortion caused by partial functions. The use of these rules will be demonstrated by means of a verification case study.
Analysis of Sci-Hub downloads of computer science papers
Authors: Andročec Darko 
Published: August 2017

AbstractThe scientific knowledge is disseminated by research papers. Most of the research literature is copyrighted by publishers and avail- able only through paywalls. Recently, some websites offer most of the recent content for free. One of them is the controversial website Sci-Hub that enables access to more than 47 million pirated research papers. In April 2016, Science Magazine published an article on Sci-Hub activity over the period of six months and publicly released the Sci-Hub’s server log data. The mentioned paper aggregates the view that relies on all downloads and for all fields of study, but these findings might be hiding interesting patterns within computer science. The mentioned Sci-Hub log data was used in this paper to analyse downloads of computer science papers based on DBLP’s list of computer science publications. The top downloads of computer science papers were analysed, together with the geographical location of Sci-Hub users, the most downloaded publishers, types of papers downloaded, and downloads of computer science papers per publication year. The results of this research can be used to improve legal access to the most relevant scientific repositories or journals for the computer science field.

Abstract
Introduction. Proteinuria after renal transplantation increases the risk of graft failure and mortality. The aim of the study was to determine the prevalence and causes of proteinuria in kidney transplant recipients. Methods. All kidney transplant recipients followed up in our clinic were included in the study. As a center protocol 24-hour urine collections were used to quantify protein excretion with 3-month intervals posttransplantation during the first year, and yearly thereafter. The etiology of chronic kidney disease and demographic characteristics of the study group were obtained from outpatient records. Data regarding the immunosuppressive regimens used, 24-hour proteinuria levels and creatinine clearences, new-onset hypertension, new-onset diabetes mellitus, rejection episodes, infections like cytomegalovirus (CMV) and polyoma (BK), and biopsy findings were noted. Results. A total of 260 kidney transplant recipients (97 females, mean age 42.3±12.3 years) were evaluated. Median follow-up period was 36 months; 137 of all transplantations were from living donors. Mean age of donors was 42.7±15 years and 133 were female. Proteinuria with protein excretion ≥300 mg/d was present in 35.4% of patients. The most common cause of biopsy-proven proteinuria was transplant-specific conditions (acute rejection, and borderline changes). Conclusion. The prevalence of proteinuria was 35.4%. The transplant-specific diagnoses were the most likely causes. Even in nonnephrotic ranges it was associated with decreased graft survival.

Abstract
Introduction. Assessment of renal function is a crucial component of donor evaluation. The higher measured donor GFR is independently associated with a better allograft outcomes in living donor kidney transplantation (LDKT). Monitoring graft function and estimation of GFR is a recommended method for patients’ follow-up in posttransplantation period. The aim of our study was to investigate the correlation of directly measured GFR of donated kidney with estimated GFR through creatininebased formulas and to detect impact factors on the graft function at 12 months posttransplantation. Methods. Fifty LDKT patients (related and nonrelated donors) with stable renal function in a period of 12 months after transplantation were included in our study. The mean recipient age was 30.7±9.6 years, and donor age 55.45±9.41 years. The mean directly measured donated kidney GFR was 47.61±5.72 ml/min. Graft function was estimated at 3, 6 and 12 months by 3 formulas: Cockcroft- Gault (C-G), MDRD 6 variables and Nankivell. Direct correlation of estimated with measured radiolabeled 99mTc DTPA GFR was performed. Various impact factors such as donor age, dialysis vintage and different calcineurin inhibitors as a part of immunosupression were evaluated. Results. Estimated GFR at 12 months with MDRD, Cockroft Gault, and Nankivell formulas was 72.65±22.6, 94.25±36.42, and 81.78±17.89 ml/min, respectively. The highest estimated GFR was obtained with C-G formula at all three time points. The estimated allograft GFR did not correlate with directly measured GFR of donated kidney. Donor age well correlated with the graft function at 12 months. Allografts from standard criteria donors-SCD (<60 years) had better function than allografts form expanded criteria donors-ECD (>60 years). The highest GFR was estimated with C-G equation (106.08±39.26 ml/min), while GFR estimated with Nankivell was 86.86±15.30 ml/min, and with MDRD 79.67±20.28 ml/min, presenting patients in stage 2 of chronic kidney disease. Duration of hemodialysis treatment under 24 months showed better graft function estimated by C-G at 12 months (102.23±38.86 ml/min), compared to that above 24 months of HD (77.84±18.11 ml/ min). Different type of calcineurin inhibitors did not influence on the graft function at any time point. Conclusion. Creatinine-based formulas for estimation of the graft function did not correlate with directly measured function of the donated kidney with radiolabeled isotopes, nor between each other. Hence, the monitoring of the graft function should be done by a single formula in the posttransplantation period. Expectedly, a better graft function was observed in young donors (standard criteria) and in patients with shorter hemodialysis treatment.

Authors: Elyigit Faruk , Akar Harun , Soyaltın Utku Erdem , Ekinci Ferhat 
Published: August 2017

Abstract
Metformin is a widely used oral anti-diabetic agent that decreases insulin resistance. Lactic acidosis rarely develops with this medication. Metformin-induced hepatotoxicity has been rarely reported in the literature. We describe a patient, who presented with lactic acidosis and hepatotoxicity after ingestion of 40 pills of metformin in order to commit suicide. The most important treatment step in patients with metformin-associated lactic acidosis (MALA) is high-volume hemodialysis and hemofiltration.
Indicators of post-productivism in South Africa’s “platteland”: A second home case study of Rosendal, Eastern Free State
Authors: Hay Anette , Hay Johnnie 
Published: August 2017

AbstractThe idea of post-productivism has been found to apply extensively in developed countries, but has been studied less in developing countries. A recent study in South Africa on second homes demonstrated that some rural spaces are slowly evolving into post-productivist countrysides, especially during weekends, month-ends and peak holiday periods. Wilson and Rigg’s six indicators were utilised to assess the rural town of Rosendal in the Eastern Free State of South Africa, the adjacent black township of Mautse and the surrounding farming area, to determine whether the notion of post-productivism can be exported from the developed North to a developing world context. Some of the indicators have been found to be highly relevant in this case study, but others have been found to be nearly irrelevant. Also important to note is that the meaning of these indicators may be different when applied to the developing South.
