Thioesterase from Cereulide Biosynthesis Is Responsible for Oligomerization and Macrocyclization of a Linear Tetradepsipeptide
Authors: Boddy Christopher , Heberlig Graham
Published: March 2020

Cereulide is a cyclic depsidodecapeptide produced in Bacillus cereus by two non-ribosomal peptide synthetases, CesA and CesB. While highly similar in structure and with a homologous biosynthetic gene cluster to valinomycin, recent work suggests that cereulide is produced via a different mechanism, which relys on a non-canonical coupling of two didepsipeptide-PCP bound intermediates. Ultimately this alternative mechanism generates a tetradepsipeptide-PCP bound intermediate that is prosed to differ from the tetradepsipeptide predicted from canonical activity of CesA and CesB. To test this hypothesis, we chemically synthetize both tetradepsipeptides as N-acetyl cysteamine thioesters and probed the ability of the purified recombinant terminal CesB thioesterase (CesB TE) to oligomerize and macrocyclize each substrate. Only the canonical substrate is converted cereulide, ruling out this alternative mechanism. We also show that CesB TE can use related tertradepsipeptide substrates, such as the valinomycin tetradespipetide and a hybride cereulide-valinomycin tetradespispetide in conjunction with its native substrate to generate chimeric natural products. This work clarifies the biosynthetic origins of cereulide and provides a powerful biocatalyst to access analogs of these ionophoric forming natural products.

Published: March 2020

The vanadium redox flow battery (VRFB) is a promising energy storage technology for stationary applications (e.g., renewables integration) that offers a pathway to cost-effectiveness through independent scaling of power and energy as well as longevity. Many current research efforts are focused on improving battery performance through electrode modifications, but high-throughput, laboratory-scale testing can be time- and material-intensive. Advances in multiphysics-based numerical modeling and data-driven parameter identification afford a computational platform to expand the design space by rapidly screening a diverse array of electrode configurations. Herein, a 3D VRFB model is first developed and validated against experimental results. Subsequently, a new 2D model is composed, yielding a computationally light simulation framework, which is used to generate a dataset of 16800 electrode property combinations under four different cell voltages to track the impact of different structural parameters on the cell current density. These structure-performance relationships are quantified using Kendall $\tau$ rank correlation coefficients to highlight the dependence of cell performance on bulk electrode morphology and to identify improved property sets. This statistical framework may serve as a general guideline for parameter identification for more advanced electrode designs.
Targeted Oxidation Strategy (TOS) for Potential Inhibition of Coronaviruses by Disulfiram — a 70-Year Old Anti-Alcoholism Drug
Authors: Xu Luyan , Tong Jiahui , Wu Yiran , Zhao Suwen , Lin Bo-Lin
Published: March 2020

In the new millennium, the outbreak of new coronavirus has happened three times: SARS-CoV, MERS-CoV, and 2019-nCoV. Unfortunately, we still have no pharmaceutical weapons against the diseases caused by these viruses. The pandemic of 2019-nCoV reminds us of the urgency to search new drugs with totally different mechanism that may target the weaknesses specific to coronaviruses. Herein, we disclose a new targeted oxidation strategy (TOS II) leveraging non-covalent interactions potentially to oxidize and inhibit the activities of cytosolic thiol proteins via thiol/thiolate oxidation to disulfide (TOD). Quantum mechanical calculations show encouraging results supporting the feasibility to selectively oxidize thiol of targeted proteins via TOS II even in relatively reducing cytosolic microenvironments. Molecular docking against the two thiol proteases Mpro and PLpro of 2019-nCoV provide evidence to support a TOS II mechanism for two experimentally identified anti-2019-nCoV disulfide oxidants: disulfiram and PX-12. Remarkably, disulfiram is an anti-alcoholism drug approved by FDA 70 years ago, thus it can be immediately used in phase III clinical trial for anti-2019-nCoV treatment. Finally, a preliminary list of promising TOS II drug candidates targeting the two thiol proteases of 2019-nCoV are proposed upon virtual screening of 32143 disulfides.

Authors: Lagerqvist Nina , Löf Emma , Enkirch Theresa , Nilsson Peter , Roth Adam , Jernberg Cecilia
Published: March 2020

An outbreak of gastroenteritis with 83 cases occurred at a conference venue in November 2017 in Halland County, Sweden. Stool samples from two venue visitors and a symptomatic secondary case attributed to household transmission were PCR-positive for the ipaH gene, a target found in both Shigella spp. and enteroinvasive Escherichia coli (EIEC). EIEC was isolated from stool samples and whole genome sequencing analysis confirmed EIEC O96:H19 to be the aetiological agent. A cohort study was conducted among venue attendees and employees and the findings implicated contaminated leafy greens as the vehicle of infection, however, no microbiological evidence could support the study results. Here, we report the investigation into the first recorded EIEC outbreak in Sweden and illustrate the challenges associated with the differential laboratory diagnostics of Shigella/EIEC in an outbreak setting.

THE NAVIER-STOKES-CONTINUITY EQUATION SOLVER BASED ON ARTIFICIAL COMPRESSIBILITY METHOD
Authors: Jalaali Bahrul
Published: March 2020

Fluid dynamics analysis can be accurately approximated by using a computer-based numerical method. Rely on the mass and momentum governing equation, the mathematics model for the compressible condition is numerically difficult to overcome. Through an artificial compressibility method, the quasi-compressible condition solution can be simplified. This study will investigate the classical lid-driven cavity case model to affirm the artificial compressibility method. The result shows that the current model is in-line with the previous study for the lid-driven cavity case. A conventional benchmark with the previous numerical study is shown as well.

Atisbos del “Cosmopolitismo crítico” en la Corte Interamericana de Derechos Humanos
Authors: Delgado Parra Concepción
Published: March 2020

El texto que se presenta a continuación propone un acercamiento al “Cosmopolitismo crítico” de Seyla Benhabib para discutir una alternativa al desafío “soberanía democrática versus normativa de derechos humanos”, que contribuya a la elaboración del discurso ético sobre el que se sostiene el desarrollo y contenido de la jurisprudencia de la Corte IDH. Con este propósito, se discuten tres aspectos: 1. Acercamiento al orden normativo de justicia trasnacional y democracia propuesto por Rainer Forst para identificar el lugar de la justicia y su justificación como dos principios sobre los que se deposita el cosmopolitismo crítico. 2. Características del cosmopolitismo crítico y el papel de las “iteraciones democráticas”. Y, 3. Atisbos del cosmopolitismo crítico en la jurisprudencia de la Corte Interamericana de Derechos Humanos.
Caso “Gelman vs Uruguay”: una revisión bajo la idea de Razón Pública de John Rawls
Authors: Mex Ávila Luis Fernando
Published: March 2020

Aquí se desarrollará una crítica a la resolución de la Corte IDH, referente al Caso Gelman vs Uruguay, desde la concepción de “razón pública” de John Rawls, así como su extensión al uso de este por parte de los Tribunales. Lo anterior pretende poner de manifiesto, las “tensiones democráticas” que se hacen presentes en esta sentencia si se le mira bajo una concepción de legitimidad. En este sentido, el texto examina la decisión de la Corte respecto a la Ley de Caducidad uruguaya puesto que, en ella, se termina por declarar inválida una norma que, a pesar de ser polémica, pareciera fungir como una manifestación del “Pueblo Uruguayo” legítima en términos democráticos y constitucionales.

Esto con miras a intuir los conceptos de retraimiento y amistad dispuestos sobre el cuestionamiento de lo común.
Problemáticas contemporáneas de la liber-acción propuesta por Enrique Dussel: caducidad y violencia
Authors: Marcos Jairo
Published: March 2020

Surgidas en la década de 1970, las filosofías de la liberación de raigambre latinoamericana y repercusión subalterna son conscientes de que las dependencias continúan arrinconando en las periferias a los nadies. La inhumanidad es hoy tan vergonzante como siempre, pero ¿se puede seguir hablando de liberación o ésta ha pasado ya de moda? El momento de ruptura con respecto a la Voluntad de poder se deposita idealmente en la educación transformadora, que sin embargo no cubre todas las situaciones posibles: es poco habitual que la apertura en lo Mismo hacia el Otro plural se produzca de forma pedagógica y progresiva. La pregunta no puede postergarse por más tiempo: ¿acaso es posible resolver todos los conflictos sin violencia alguna?

Published: March 2020

The effects of organic and inorganic fertilizers on the growth and yield performance of soybean was evaluated at ALIAS R & DE Center, Pampanga State Agricultural University, PAC, Magalang, Pampanga from December 2017 to March 2018. It was laid out in the field according to the procedures of randomized complete block design (RCBD) with three replications. The treatments tested were T1 – No fertilizer application, T2 – 500 kg/ha of Power Organic, T3 – 21.74 kg/ha of Urea and 150 kg/ha of Super Phosphate, T4 – 250 kg/ha of Power Organic + 10.87 kg/ha of Urea and 75 kg/ha of Super Phosphate, T5 – 375 kg/ha of Power Organic + 5.44 kg/ha of Urea and 37.5/ha of Super Phosphate, T6 – 125 kg/ha of Power Organic + 16.31 kg/ha of Urea and 112 kg/ha of Super Phosphate. Results revealed that all organic and inorganic fertilizers applied crops were significantly different in terms of days to flowering, plant height at flowering, length of pods, weight of 100 seeds and computed seed yield per hectare. Cost and return analysis reveals that the highest net income and return of investment was derived from the combination of 50 % organic and 50 % inorganic fertilizer. Conjunctive use of organic and inorganic fertilizer, that is, 50 % recommended rate of organic fertilizer (Power organic) along with 50 % recommended rate of inorganic fertilizer (Urea and Super Phosphate) can enhance the growth and yield performance of soybean and can help the farmer to increase their production with higher net income.

Agarwood is a fragrant non-wood product. West Nusa Tenggara is a site for growing agarwood tree. In the world, especially in the Middle East, the Arabian people are the most consumptive to agarwood. For demand to agarwood is high but the agarwood in forest is rarely, making the price of agarwood in the market is expensive. Agarwood farmers in West Nusa Tenggara could not be able to supply the demand because agarwood product from natural forest is very little. In answering the high demand to natural agarwood, the farmers develop agarwood cultivation. Agarwood trees were planted in theirs yards and gardens, and after some years the agarwood trees inoculated with inoculation as a way to get aromatic resin. Developing agarwood plantation of farmer can become a potential tourism destination in West Nusa Tenggara to add pre-existing tourist attraction. Through this paper, I would like to explain why agarwood plantation and all activities following it become a potential tourism attraction which will improve welfare of agarwood farmers in West Nusa Tenggara, especially in Lombok Island.

Pulmonary tuberculosis is one of the leading causes of infectious disease related mortality. Transbonchial biopsy and bronchoalveolar lavage smear obtained by bronchoscopy provides greater quantity of material for analysis, thus increases the chances of diagnosing the disease. Objectives: To diagnose sputum smear negative pulmonary tuberculosis patients by Transbronchial Biopsy and Bronchoalveolar smear keeping bronchoalvelar lavage culture as gold standard. To calculate and compare the diagnostic accuracy of transbronchial biopsy and bronchoalveolar lavage smear in sputum negative patients. Study Design: Cross-sectional validation study. Setting: Department of histopathology, Foundation University Medical College, Islamabad and Department of Pulmonology and Microbiology, Fauji Foundation Hospital, Rawalpindi. Period: From May 2016 to May 2017. Materials & Methods: It comprised 96 patients who underwent bronchoscopy. Transbronchial biopsy, bronchoalveolar lavage smear preparation and bronchoalveolar lavage culture was performed on specimens of all patients. Results: Out of 96 patients 22 (22.91%) patients were actually having tuberculosis whereas 74 (77%) had only clinical and radiological suspicion of tuberculosis. The mean age of patients was 43 years with a standard deviation of ±19.1 .The age range was 12-80 years. The sensitivity, specificity, positive predictive value, negative predictive value and true positives of transbronchial biopsy were 68.1%, 77%, 46.8%, 89% and15.62% while the values for bronchoalveolar lavage were 50%, 97.29%, 84.6%, 86.7% and 11.45% respectively. Thus, the diagnostic accuracy calculated for transbronchial biopsy and bronchoalveolar lavage was 75% and 13.54% respectively. Conclusions: Bronchoscopy should be done in all sputum negative tuberculosis patients having strong clinical and radiological suspicion to obtain transbronchial biopsy and bronchoalveolar lavage for timely diagnosis, treatment and prevention of disease transmission as well as to avoid empirical treatment and its side effects in patients having no tuberculosis. The diagnostic accuracy of transbronchial biopsy is almost 5 times more compared to bronchoalveolar lavage smear.

Hip fracture is the leading cause of morbidity in the geriatric population of Pakistan. The anthropometric parameters and bone mineral density is closely associated with risks of femur fracture on the elderly. Objectives: This study is oriented upon the relation of anthropometric parameters and bone mineral density with femur neck fracture in the elderly. Study Design: Cross sectional study. Setting: Mardan Medical Complex, Mardan, Pakistan. Period: May 2015 to October 2015. Material & Methods: A total of 121 patients both male and female from 50 to 70 years old were included in the study. Thirty patients had a history of hip fractures while 91 patients were age matched controls. Patients below 40 years and above 70 years were excluded as well as patients on long term steroids, or rheumatoid arthritis and bed ridden. Data regarding patient’s age, sex as well as height and weight were recorded. Both height and weight were measured in light clothing without shoes. Weight was measured using an electronic scale and standing height was measured to the nearest centimeter with a stadiometer. Body mass index was calculated as weight (kg)/height (m).2 Bone mineral density was assisted by Quantitative ultrasound (QUS) heel, using WHO T-score. The Anthropometric parameters and bone mineral density of hip fracture cases were then compared with age-matched control groups. For statistical analysis of data, we used SPSS 20. Results: The average age of hip fracture patients were higher than the control. Females with hip fracture found taller, lighter and had low BMI (p=0.003). Bone mineral density of hip fracture cases were significantly lower as compared to T-score of control (p=0.0001). Height correlated significantly with BMI (r=2.68 p=0.005) and with BMD (r=2.56 p=0.005). Weight had significant correlation with BMI (r= 0.488 p=0.0001) and with BMD (r=0.212 p=0.002). Conclusion: The anthropometric parameter, especially body mass Index and bone mineral density seems to be associated with the risk of femur neck fracture.

Objectives: To assess the correlation of different obstetrical factors with the hemoglobin level in multiparous pregnant females in Taif KSA. Anemia in pregnancy is a multifactorial phenomenon, among which obstetrical factors like parity, previous H/O abortions, inter pregnancy interval, mode of delivery etc are frequently associated. Study Design: Observational study. Setting: Outpatient department in King Faisal Hospital (KFH), Taif, Saudi Arabia. Period: 1st June 2018 and 31st August 2018. Material & Methods: Conducted in 200 pregnant women by random sampling technique. Hemoglobin value and all patient’s data was noted. All data was fed to SPSS version 23.0 and statistically analyzed using chi square test for qualitative and student’s t test for quantitative data. Results: The study was conducted in 200 patients that showed that there was no statistically significant association of increasing parity, inter pregnancy interval, mode of delivery (NVD or Cesarean section) & history of anemia and PPH in preceding pregnancy with the Hemoglobin level. While history of previous abortion is associated and a risk factor for anemia in pregnancy, 50% with history of 01 previous abortion had anemia while 100% of the cases with history of 02 previous abortions had moderate anemia. (Table-II). This association was observed statistically significant with p value of 0.001. Conclusion: This study concluded that anemia is a predictable as well as preventable entity. Obstetrical factors may be the contributory factors of anemia in pregnancy. Health education awareness programs, regular antenatal visits and iron supplements can be helpful to improve heath of pregnant women.

Authors: Tamaela Gysber J.
Published: March 2020

Association is a technique in data mining used to identify the relationship between itemsets in a database (association rule). Some researches in association rule since the invention of AIS algorithm in 1993 have yielded several new algorithms. Some of those used artificial datasets (IBM) and claimed by the authors to have a reliable performance in finding maximal frequent itemset. But these datasets have a different characteristics from real world dataset. The goal of this research is to compare the performance of Apriori and Cut Both Ways (CBW) algorithms using 3 real world datasets. We used small and large values of minimum support thresholds as atreatment for each algorithm and datasets. As a result we find that the characteristics of datasets have a signifcant effect on the performance of Apriori and CBW. Support counting strategy, horizontal counting, showed a better performance compared to vertical intersection although candidate frequent itemsets counted was fewer.

Objective: To understand the perceptions and self-care needs of patients regarding intestinal stoma in the preoperative period. Method: Qualitative exploratory research performed in a surgical unit of a hospital in southern Brazil, with seven patients in the preoperative period of intestinal surgery. The data were collected through semi-structured interviews and submitted to thematic analysis of content. From the data analysis three thematic categories emerged: therapeutic itinerary and associated feelings; knowledge, perceptions and expectations regarding intestinal ostomy; and self-care needs of the patient with intestinal stoma. Results: The participants showed a lack of knowledge about intestinal stoma and evaluated this possibility as something negative, which would bring changes in lifestyle habits, with little information about care. Conclusion: It is evident the need to provide preoperative orientation for better acceptance and strengthening of the patient’s self-care in the postoperative period, appointing the nurse as an essential professional in this process.
ALUR TRANSMISSION OF RELIGIOUS KNOWLEDGE AND ISLAMIC THOUGHT DALAM ISLAMIC THOUGHT; AN INTRODUCTION KARYA ABDULLAH SAEED TERBITAN ROUTLEDGE 2006
Authors: Putra Ahmad
Published: March 2020

This paper describes the fundamental teachings of the Prophet Muhammad, the development of religious knowledge, and the social and political context that shaped the intellectual tradition of Islam. Abdullah Saeed, in the transmission of spiritual experience and Islamic thought, introduced the basic teachings of Islam. The emergence of Islam is closely related to the history of its birthplace, the city of Mecca. Besides, Abdullah Saeed also discussed the beginning of the development of religious knowledge, which was immediately explained by the Qur'an and the emergence of sects that influenced the course of change towards truth. Each of these sects and sects has its doctrine, and if there is anything against it, there is undoubtedly a separate assessment of the differences that are believed. Several groups with various theological or religio-political orientations emerged. Among them are Kharijis (khawarij), Shia, Qadaris (qadariyya), Mu‘tazilis (mu‘tazila), Jabris (jabriyya) and Murji'is (murji'a).

Authors: Lima Jr. Roberto Guião de Souza , Mahler Claudio Fernando
Published: March 2020

This study involves the evaluation of new composting systems for the treatment of organic solid waste that has low environmental impact. Two composting devices were developed, with four types of management. Their behavior was analyzed regarding temperature, gas production, moisture, leachate and percolated water production, compost maturation, nutrient presence, pH and water heating, which can be seen as an energy gain in addition to the economic viability of the process. The proposed composting techniques kept the waste at thermophilic temperatures for more than 20 days, with no significant emission of CH4, under aerobic conditions by passive aeration, without leachate generation. These results can be partially attributed to the suspension of the compost on pallets, the residue composition chosen in the experiments and the boundary conditions of the compartments. The energy recovery test, through water recirculation inside the compost, presented temperatures that reached 51°C after 24 h of recirculation, and were maintained throughout the process, 20 days, demonstrating its effectiveness. The proposed models are environmentally viable, minimizing gas emissions and leachate generation compared to landfill or industrial composting plants. They can be used in industrial kitchens, residential complexes, shopping malls and other small and medium solid waste generators. In addition, the solution presented in this study avoids the transportation of waste over medium and long distances, which also brings a significant reduction in energy expenses, and in the case of landfills, it avoids occupation for long periods, thus reducing emissions of gases and leachate, whose control and treatment are expensive.

Between 2010 and 2015, the Bellechasse Regional County Municipality (Bellechasse RCM) was affected by particularly noxious odors issuing from its Municipal Solid Waste Landfill (Bellechasse RCM MSWL) in Armagh, Canada. A study carried out in 2015-2016 by Centre de recherche industrielle du Québec (CRIQ) confirmed that it was still possible for hydrogen sulfide (H2S) emissions to cause odor issues in and around the site. The experimental project carried out by CRIQ in cooperation with Bellechasse RCM, Englobe, Quebec City and the Regroupement des récupérateurs et des recycleurs de matériaux de construction et de démolition du Québec (represented by AIM Éco-centre) made it possible to test three (3) different industrial residue as an alternative cover materials on site and study how they controlled H2S emissions, volatile organic compounds (VOCs) and odors at the Bellechasse RCM’s landfill. The site was monitored from November 2016 to September 2017 to confirm the effectiveness of alternative biofiltration cover materials (soil + compost), domestic waste incineration bottom ash and 0 to 2.5-inch concrete residues and to compare the results with the sand cover currently used as the cover material. Effectiveness was determined by measuring the Area Source Emission Rate (ASER) with a 3 m x 3 m static flux chamber developed for the project. Methane measurements were concomitantly taken to confirm that the biogas could escape through the cover materials. The monitoring results made it possible to demonstrate that domestic waste incineration bottom ash as well as 0-2.5 in. concrete received the highest load of H2S and showed an H2S capture performance of greater than 83ϿFor volatile organic compounds, materials such as 0-2.5 in. concrete and the alternative biofiltration cover materials were most effective for capture (greater than 73Ͽfor the highest loads. The lowest content of CH4 after covering was measured for the alternative cover materials. The site where the incineration bottom ash was used managed to decrease odors by ±200 odor units. Overall, we have demonstrated in this project, the capacity of different alternative cover materials under real condition for the control of gas emissions from landfill.

Published: March 2020

The increasing growth of cassava agro-industries in Nigeria has led to the enormous generation of cassava peels waste. The feasibility of generating biogas and biofertilizer for both domestic and agricultural applications from cassava peels waste inoculated with cow dung was investigated. Fresh and stale cassava peels were used in the study. Three pretreatment chemicals such as sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2 and ammonium chloride (NH4Cl) buffer solutions were used in pretreating the cassava peels and cow dung slurry. Six batch anaerobic biodigesters of 10-litre capacity each were used in this study for 40 days retention period. The pH, temperature, and volumes of biogas and methane produced were monitored and recorded daily. The fertilizer qualities (total solids, volatile solids, % phosphorus, % nitrogen, etc.) of the digester slurry and the digester sludge after 40 days digestion were determined using official methods of analysis of Association of Official Analytical Chemists (AOAC). The results showed that the amount of biogas generated is 2540 cm3/day. The stale cassava peels and cow dung slurry and the use of NH4Cl pretreatment chemical gave the best biogas production and methane yield of 104,961cm3 and 62.3% respectively. The digester sludge from the anaerobic digestion of cassava peels and cow dung showed and demonstrated good biofertilizer qualities.

Published: March 2020

In the present article we give the results for ultra-fine particles and microparticles at a landfill of municipal waste, taking into consideration various factors. The landfill is a large-scale source of dust. There is little knowledge in terms of fractional composition of dust particles. We have performed concentration measurements of the number of ultrafine (10 to 100 nm) and microparticles (0.1 to 10 μm) in the field conditions of the municipal waste landfill using the TSI Technique (Optical particle sizer 3330 and Nanoscan SMPS nanoparticle sizer 3919). The particle number concentration in the atmosphere in case of dry and windless weather conditions at the landfill was in the range of about 2,500 to 5,500 of ultrafine particles per cm3. The mass concentrations of the microparticles was in the range of 29 to 163 μg.m-3 (assuming ρ=1 g.cm-3). There was an evident trend of increase of concentration of the ultrafine particles and microparticles in the lower location of the landfill occuring in the case of dry and windless weather conditions. The surprising finding was that passing haulage vehicles and in particular the operation of the compactor increase the mass concentration of microparticles, but they do not increase the concentration of the number of microparticles or even of ultrafine particles.
