S3 (SALE SALAM SYSTEM) : OPTIMALISASI AKAD SALAM OLEH PERBANKAN SYARIAH DALAM MENGATASI TALLAQI RUKBAN PADA KOMUDITAS PERTANIAN (STUDI KASUS PETANI DI DESA NGANDONG YOGYAKARTA)
Authors: Umah Khurul Aimmatul , Luthfi Faisol , Widiastuti Tika
Published: January 2019

Akad salam merupakan salah satu akad jual beli yang saat ini menjadi salah satu produk perbankan syariah untuk sektor pertanian. Namun pada saat ini implementasi akad salam belumlah optimal dibandingkan negara-negara lain seperti Sudan dan Pakistan yang menjadikan akad salam sebagai produk andalan dalam meningkatkan kesejahteraan petani. Pada penelitian ini penulis ingin menganalisis kolerasi positif dalam penerapan akad salam secara optimal, sehingga dapat menagatasi permasalahan tallaqi rukban yang saat ini marak terjadi. Tallaqi rukban tentu sangat menyengsarakan para petani karena para tengkulak (pemasok) biasa memanfaatkan ketidaktahuan petani terhadap harga pasar sehingga dapat membeli dengan harga yang lebih murah demi memperoleh untung yang sangat besar, selain itu dengan adanya pengembangan konsep salam ini dapat meningkatkan perekonomian para petani karena dipermudah dalam proses distribusi hasil panen. Penelitian ini bersifat kualitatif induktif dalam artian menerangkan dari fakta ke teori, dengan jenis penelitian berupa studi kasus. Adapun teknik pengumpulan data dilakukan melalui dua cara yaitu, wawancara kepada pihak perbankan, dan petani padi di desa Ngandong Yogyakarta, serta teknik dokumentasi. Jenis penelitian ini adalah Studi kasus dengan teknik analisis data menggunakan metode Spradley atau ethnograpi, sehingga dapat menyajikan hasil analisis secara deskriptif guna menjawab tujuan penelitian. Berdasarkan analisis yang dilakukan oleh penulis maka dapat disimpulkan bahwa dengan adanya akad salam oleh perbankan syariah yang dapat memasarkan penjualan padi milik para petani di desa ngandong. Hal ini sangat berperan dalam mengatasi tallaqi rukban yang dilarang oleh syariat islam. Optimalisasi akad salam memiliki kolerasi positif dalam peningkatan perekonomian petani padi karena mendorong penaikan harga jual padi oleh petani dan menghindari kecurangan para tengkulak dalam merekayasa harga pasar.

Subjects in this study were students of class VIII Junior High School (SMP) totaling 32 people. The data collection tool used in this study is a test that totals ten questions in the form of a description. This type of research is a qualitative descriptive study. Data collection techniques are carried out by tests, observation, interviews, and documentation. Data analysis techniques were carried out by data reduction, data presentation, and concluding. The results showed that students had difficulty determining the sequence of numbers, determining the configuration of a sequence of numbers, determining the arithmetic series, determining the number of n first arithmetic series terms, determining the first term n row geometry, and determine the number of n first terms of the geometry series. The causal factor is that students are not able to distinguish the general formula concept of a sequence and the concept of configuration patterns from a sequence of numbers, operating error calculations and not understanding integer ranks.
Foucault, the “Facts,” and the Fiction of Neutrality: Neutrality in Librarianship and Peer Review
Authors: Johnson Heidi R.
Published: January 2019

This paper brings together two discourses in librarianship, that of neutrality in the context of library services, and that of peer review, which is of concern for librarianship as it moves more into the realm of scholarly communication. It points out the shortcomings of this ethical principle within the context of library services, using LIS literature on the opposition between neutrality and the commitment to social justice. It also uses Foucault’s theories on discipline, and knowledge and power, and Latour and Woolgar’s analysis of the construction of scientific facts, to critique the concept of neutrality. Then it asks how that critique applies to the practice of peer review, in which the expectation is that reviewers will be neutral or impartial judges of manuscripts. Findings suggest that the principle of neutrality, with a slightly different meaning in this context, does have useful applications to peer review, ensuring fairness. Although neutrality may never be possible completely, cross-disciplinary literature suggests ways to limit the effects of bias. Thus, librarians can better understand the different meanings of neutrality in these different contexts, including its usefulness and limitations.
Library Councils and Governance in Canadian University Libraries: A Critical Review
Authors: Revitt Eva , Luyk Sean
Published: January 2019

Despite the nearly 40-year history of library councils in Canadian academic libraries, scholarly literature regarding library governance and decision-making processes within the context of Canadian university libraries is almost non-existent. Nevertheless, there is evidence of a general disenfranchisement of librarians from significant decisions affecting library operations, resources, services, and the appointment and evaluation of senior administrative positions. Furthermore, it is evident that library councils in Canadian academic libraries, where they do exist, function primarily as information-sharing forums rather than as the collegial decision-making bodies they were originally intended to be. Through a close examination of the CAUT Bulletin, this paper traces the development of library councils in Canadian academic libraries. Within the framework of institutional theory and drawing from librarianship, management, and educational administration literature, the paper proceeds to critically discuss systematic barriers to collegial governance in academic libraries. Historical and anecdotal evidence suggests that administrative resistance is a continued and key obstacle to the democratization of decision-making processes in Canadian academic libraries.

Authors: Hasan Mohammad Quamrul , Mondal Nelson Taposh , Hossain Mahbub , Perveen Irin
Published: January 2019

Background: Although endoscopic retrograde cholangiopancreatography (ERCP) was first described as a diagnostic technique, now-a-days we mainly do ERCP with a therapeutic intent for management of various biliary and pancreatic diseases.

Objectives: This study intends to find out the diagnosis obtained by ERCP procedure and the therapeutic interventions done for appropriate cases in a tertiary level hospital in Bangladesh.

Materials and Methods: This prospective observational study was performed in the Department of Gastroenterology in Enam Medical College & Hospital over a period from June 2014 to October 2016. Eighty patients, aged 15–70 years, were selected only for therapeutic ERCP. They were diagnosed and selected after taking history, physical examination and appropriate investigations. ERCP was done under short-term general anesthesia or deep sedation by using propofol or fentanyl. Results are shown in tables.

Results: Majority of the cases were choledocholithiasis (53.75%) followed by cholangiocarcinoma (11.25%), ampullary carcinoma (8.75%), carcinoma of the gall bladder (6.25%), biliary ascariasis (6.25%), biliary stricture (5%), papillary stenosis (5%), chronic pancreatitis (2.5%) and sludge in the CBD (1.25%). Types of therapeutic intervention depended on diagnosis. Papillotomy with stone removal was done in patients with choledocholithiasis. Papillotomy with stenting was done in the patients with cholangiocarcinoma, ampullary carcinoma, gall bladder carcinoma, biliary stricture and paillary stenosis. Papillotomy with worm extraction was done in cases of biliary ascariasis. Papillotomy with clearing of sludge was done for sludge in the CBD and only papillotomy was done in two patients of chronic pancreatitis.

Conclusion: In this study we found that choledocholithiasis and biliary tract malignancy were the two major ERCP findings. Therapeutic interventions were done according to diagnosis. The most common therapeutic intervention was papillotomy with stone removal. Next common intervention was papillotomy with stenting.

Evaluation of the Genotype-dependency of the Leafbased Regeneration and Transformation System in Maize
Authors: Ebrahimzadeh Saeideh , Ahmadabadi Mohammad
Published: January 2019

Tissue culture and genetic transformation in maize are very laborious. The existing regeneration methods, which mainly use immature embryos as starting material, are highly genotype-dependent. Leaf segments can be used as an alternative explant source to produce embryogenic calli. Although a reliable leafbased regeneration and transformation system has been recently reported for maize, however, the genotype-dependency of this method has not been described yet. To this end, we evaluated the production of embryogenic calli from young leaves of several maize genotypes. The results showed that, overall callus induction potential as well as embryogenic callus induction rate is significantly different among the tested genotypes, demonstrating the genotypedependency of this system. However, induced embryogenic calli from different genotypes remained their embryogenic capability during several callus multiplication rounds. In addition, embryogenic calli showed high potential for biolistic-based genetic transformation, as revealed by transient GUS expression.

An evaluation of the protein quality of some macedonian edible Boletaceae mushrooms
Authors: Bauer Petrovska Biljana
Published: January 2019

The nutritional quality of mushroom protein varies and is strongly affected by the relative proportion of each amino acid. Thus, the purpose of this study was to estimate the concentration of the amino acids present in mushroom proteins in order to evaluate the protein nutritional value. In this investigation fifteen field-collected mushroom samples of the Boletaceae family from various parts of Macedonia were included. After acid hydrolysis and pre-column derivatisation with phenyl isothiocyanate (PITC) determination of seventeen amino acids was carried out by the HPLC method. Tryptophan was determined spectophotometrically in the alkaline hydrolysates. The dietary protein quality of the investigated mushrooms was evaluated by comparison of the essential amino acid content with the reference FAO/WHO pattern. Essential amino acids made up 47-75 % of all determined amino acids depending on the origin and the species of the fruit body. Lysine was the most often found limiting amino acid in the investigated mushrooms samples. The nutritional value of proteins calculated by biological value, protein ratio, chemical score and essential amino acid index was very high in the majority of mushrooms studied. The biological value of the mushroom protein varied from 51.3 to 78.9 %. Protein amino acids accounted for about 66.7 % of the total nitrogen, suggesting that a practical nitrogen to protein conversion factor for this Macedonian edible Boletaceae mushroom may be considered to be about 4.17 on average.

Published: January 2019

Ascorbic acid is considered to be one of the most important antioxidants in plants and plays a vital role in the adaptation of plants to unfavorable conditions. In the present study, an ascorbate oxidase gene (Solyc04g054690) was over-expressed in cherry tomato cv. West Virginia 106 lines and compared with previously studied RNAi silenced ascorbate oxidase lines. Two lines with lower ascorbate oxidase activity (AO−15 and AO−42), two lines with elevated activity (AO+14 and AO+16), and the non-transgenic line (WVa106) were grown and irrigated with 75 mM and 150 mM NaCl in 2015 and 2016. Growth, yield, and chemical composition of the lines under salinity stress were evaluated. Lines with lower ascorbate oxidase activity resulted in higher plant growth parameters (plant height, leaf number, flower, and cluster number in 2015 and stem diameter and flower number in 2016), and improved fruit quality (firmness in 2016 and soluble solid content in 2015) and total yield per plant under salinity stress over both years. In addition, we show that ascorbic acid, lycopene, and carotene contents of fruits were higher in lines with lower ascorbate oxidase activity compared to lines with elevated activity and the non-transgenic line under conditions of moderate and high salinity in both years.
Long Non-Coding RNAs: Rising Regulators of Plant Reproductive Development
Authors: Yu Tongtong , Zhu Hongliang
Published: January 2019

Long non-coding RNAs (lncRNAs) exert a multitude of functions in regulating numerous biological processes. Recent studies have uncovered a growing number of lncRNAs within the plant genome. These molecules show striking tissue-specific expression patterns, suggesting that they exert regulatory functions in the growth and development processes of plants. Plant reproductive development is tightly regulated by both environmental and endogenous factors. As plant reproductive development is a crucial aspect of crop breeding, lncRNAs that modulate reproductive development are now particularly worth regarding. Here, we summarize findings that implicate lncRNAs in the control of plant reproductive development, especially in flowering control. Additionally, we elaborate on the regulation mechanisms of lncRNAs, tools for research on their function and mechanism, and potential directions of future research.

Published: January 2019

Fusarium wilt is considered the most devastating banana disease incited by Fusarium oxysporum f. sp. cubense (FOC). The present study addresses suppressive subtraction hybridization (SSH) analysis for differential gene expression in banana plant, mediated through FOC and its interaction with biocontrol agent Trichoderma asperellum (prr2). SSH analysis yielded a total of 300 clones. The resultant clones were sequenced and processed to obtain 22 contigs and 87 singleton sequences. BLAST2GO (Basic Local Alignment Search Tool 2 Gene Ontology) analysis was performed to assign known protein function. Initial functional annotation showed that contig 21 possesses p38-like endoribonuclease activity and duality in subcellular localization. To gain insights into its additional roles and precise functions, a sequential docking protocol was done to affirm its role in the defense pathway. Atomic contact energies revealed binding affinities in the order of miRNA > phytoalexins > polyubiquitin, emphasizing their role in the Musa defense pathway. Contig 21 and polyubiquitin showed an atomic contact energy value of −479.60 kJ/mol, and even higher atomic contact energies were observed for miRNA (−804.86, −482.28, −494.75 kJ/mol), demonstrating its high RNA-binding properties. Phytoalexin contig 21-interacting interfacial residues were identified as rigid (10)/non-rigid (2) based on Bi, N values, and B-factor per residue. Hence, based on these results, contig 21 was characterized as a NPR1 (non-pathogenesis-related protein) homolog that is involved in plant defense and systemic induced resistance.
PGR and Its Application Method Affect Number and Length of Runners Produced in ‘Maehyang’ and ‘Sulhyang’ Strawberries
Authors: Liu Chen , Guo Ziwei , Park Yoo Gyeong , Wei Hao , Jeong Byoung Ryong
Published: January 2019

Vegetative propagation using runner plants is an important method to expand the cultivation area for the strawberry (Fragaria × ananassa Duch.). However, excessively long runners need an increased total amount of nutrients and energy to receive elongation from mother plants, which may lead to poor growth or reduced output. The use of plant growth regulators (PGRs) is an adoptable way to solve such problems. The objectives of this experiment were to study the effects of PGRs and their application methods on the growth and development of runners, runner plants, and mother plants, and also to find effective ways to control the number and length of runners without harmful side effects. Chlormequat chloride (CCC), 6-benzylaminopurine (BA), and ethephon (ETH) at a concentration of 100 mg·L−1 were applied via three different methods: injection into crowns, medium drench, and foliar spray. The results showed that BA injection into crowns was the most effective combination among all treatments, which prominently shortened the length of runners and increased the number of runners and leaves on a single plant. Furthermore, plants with BA solution injection tended to produce stronger runners with higher fresh and dry weights, without affecting the health states of mother plants. The ETH solution seemed to have toxic effects on plants, by leading many dead leaves and weak runners, and increased activities of antioxidant enzymes. Other than the injection method, the other two application methods of the CCC solution did not significantly affect the growth and development of both cultivars. Runner plants grown for 30 days were not affected by any treatments, and they were in similar conditions. Overall, BA injection into crowns is recommended for controlling the number and length of strawberry runners.

Over the last years, we have been focused on chloramphenicol conjugates that combine in their structure chloramphenicol base with natural polyamines, spermine, spermidine and putrescine, and their modifications. Conjugate 3, with spermidine (SPD) as a natural polyamine linked to chloramphenicol base, showed the best antibacterial and anticancer properties. Using 3 as a prototype, we here explored the influence of the antibacterial and anticancer activity of additional benzyl groups on N1 amino moiety together with modifications of the alkyl length of the aminobutyl fragment of SPD. Our data demonstrate that the novel modifications did not further improve the antibacterial activity of the prototype. However, one of the novel conjugates (4) showed anticancer activity without affecting bacterial growth, thus emerging as a promising anticancer agent, with no adverse effects on bacterial microflora when taken orally.

Antioxidant activity of native vitamin C (ascorbic acid, AH2) is hampered by instability in solution. Selective loading of AH2 into the inner lumen of natural halloysite nanotubes (HNT) yields a composite nanoantioxidant (HNT/AH2), which was characterized and investigated for its reactivity with the persistent 1,1-diphenyl-2-picrylhydrazyl (DPPH•) radical and with transient peroxyl radicals in the inhibited autoxidation of organic substrates, both in organic solution (acetonitrile) and in buffered (pH 7.4) water in comparison with native AH2. HNT/AH2 showed excellent antioxidant performance being more effective than native ascorbic acid by 131% in acetonitrile and 290% (three-fold) in aqueous solution, under identical settings. Reaction with peroxyl radicals has a rate constant of 1.4 × 106 M−1 s−1 and 5.1 × 104 M−1 s−1, respectively, in buffered water (pH 7.4) and acetonitrile, at 30 °C. Results offer physical understanding of the factors governing HNT/AH2 reactivity. Improved performance of HNT/AH2 is unprecedented among forms of stabilized ascorbic acid and its relevance is discussed on kinetic grounds.

Published: January 2019

Indirect ImmunoFluorescence (IIF) assays are recommended as the gold standard method for detection of antinuclear antibodies (ANAs), which are of considerable importance in the diagnosis of autoimmune diseases. Fluorescence intensity analysis is very often complex, and depending on the capabilities of the operator, the association with incorrect classes is statistically easy. In this paper, we present a Convolutional Neural Network (CNN) system to classify positive/negative fluorescence intensity of HEp-2 IIF images, which is important for autoimmune diseases diagnosis. The method uses the best known pre-trained CNNs to extract features and a support vector machine (SVM) classifier for the final association to the positive or negative classes. This system has been developed and the classifier was trained on a database implemented by the AIDA (AutoImmunité, Diagnostic Assisté par ordinateur) project. The method proposed here has been tested on a public part of the same database, consisting of 2080 IIF images. The performance analysis showed an accuracy of fluorescent intensity around 93%. The results have been evaluated by comparing them with some of the most representative state-of-the-art works, demonstrating the quality of the system in the intensity classification of HEp-2 images.

Authors: Wilczyński Jacek , Habik Natalia
Published: January 2019

The aim of the study was to evaluate the effects of L-dopa on postural stability in Parkinson’s disease patients. In the study, we examined a group of 13 patients, members of the Parkinson’s Association. The majority of subjects were women: 8 (61.538%), while 5 (38.462%) were men. These were patients with advanced, idiopathic Parkinson’s disease. The study was performed at the Posturology Laboratory of the Faculty of Medicine and Health Sciences, UJK, Kielce (Poland). The duration of the illness was longer than 5 years. The daily L-dopa dose was between 600 and 1000 mg/d. Patients were tested for postural stability prior to taking the morning dose and again, 1 h after the 200-mg dose (Madopar 250 Tablets). The Biodex Balance System was applied in order to perform Postural Stability Testing. No statistically significant differences were found for the distribution of postural stability results before or after L-dopa administration. Nonetheless, it should be noted that all variables in the Postural Stability Test were slightly improved following L-dopa administration. The highest percentage (% Time in Zone) was noted in Zone A (the best), before (85.77%) and after L-dopa administration (95.23%). The highest % Time in Quadrant was in Quadrant IV (right posterior) both before (41.43%) and after L-dopa administration (49.54%). When comparing the distribution of postural stability variables before and after L-dopa administration, there were no significant differences between women and men.

Published: January 2019

This paper presents a study that analyses the effect of financing costs on grid parity in photovoltaic (PV) installations by applying a probabilistic methodology. Three different case studies, located in Spain, have been considered, with 500 kW, 50 kW and 5 kW grid-connected PV generators. The technical and economic calculations were performed, considering the interest rate, yield across the Spanish geography, and PV module cost as parameters. The Monte Carlo method was applied to consider the full probabilistic range of values given to the different variables. The goal of this study was to determine, for the studied cases, the levelised cost of energy (LCOE) and the internal rate of return by considering realistic values of the variables. A success rate parameter was calculated, which determined the likelihood of the number of times that the LCOE was below the retail cost of electricity. All the cases were evaluated by applying 10,000 iterations, considering the standard deviations and means defined.

Published: January 2019

In this paper, we reviewed the existing literature on the fabrication of nanocomposites based on cellulose and cellulose nanocrystals (CNCs), and analyzed their dispersion mechanism with respect to their use in the field of construction. First, the existing literature on CNC-based nanocomposites that exhibit the physical and chemical properties of nanocellulose and CNCs was reviewed. Next, keeping the use of these nanocomposites in the field of construction in mind, we determined the optimal mechanical method for their dispersion as an alternative to the currently used harmful chemical techniques. To this end, we evaluated the dispersibility of colloidal CNCs using two dispersion methods: magnetic stirring (for stirring times of 60 min, 120 min, and 180 min) and high-pressure dispersion (at pressures of 345 × 105 Pa, 1035 × 105 Pa, and 1587 × 105 Pa, and one to three dispersion passes). The optimal dispersion conditions were determined by analyzing the size and zeta potential of the CNC particles. It was found that the difference in the average diameter was reduced by approximately 76% at 1587 × 105 Pa during high-pressure dispersion.

To reduce the considerable investments of toxicity testing and protecting animal welfare, a new toxicity testing strategy based on response pathways of human cell lines has been proposed in the United States to evaluate the chemical exposure risks to human health. However, the in vitro high-throughput assays have not yet been fully applied in ecotoxicity testing. This paper proposes a framework for high-efficiency ecotoxicity testing strategies to evaluate the ecological risk of chemicals. It consists of pathway-based toxicity testing, embryo-based toxicity testing, and predictive toxicology and data extrapolation, etc., according to different situations. The results of ecotoxicity testing or data mining are analyzed together with physicochemical properties, environmental fate, and exposure data of chemicals to conduct a comprehensive risk assessment of chemicals. The framework provides valuable points to establish high-efficiency ecotoxicity testing strategies in the 21st century.
