Biosynthesis of Chlorinated Lactylates in Sphaerospermopsis Sp. LEGE 00249
Authors: Abt Kathleen , Castelo-Branco Raquel , Leao Pedro
Published: August 2020

Lactylates are an important group of molecules in the food and cosmetic industries. A series of natural halogenated 1-lactylates – chlorosphaerolactyaltes (1-4) – were recently reported from Sphaerospermopsis sp. LEGE 00249. Here, we identify the cly biosynthetic gene cluster, containing all the necessary functionalities to generate and release the natural lactylates. Using a combination of stable isotope-labeled precursor feeding and bioinformatic analysis, we propose that dodecanoic acid and pyruvate are the key building blocks in the biosynthesis of 1-4. We additionally report minor analogues of these molecules with varying alkyl chains. The discovery of the cly gene cluster paves the way to accessing industrially-relevant lactylates through pathway engineering.

Published: August 2020

Abstract: The production of olefins via on-purpose dehydrogenation of alkanes allows for a more efficient, selective and lower cost alternative to processes such as steam cracking. Silica-supported pincer-iridium complexes of the form [(≡SiO-R4POCOP)Ir(CO)] (R4POCOP = κ3-C6H3-2,6-(OPR2)2) are effective for acceptorless alkane dehydrogenation, and have been shown stable up to 300 °C. However, while solution-phase analogues of such species have demonstrated high regioselectivity for terminal olefin production under transfer dehydrogenation conditions at or below 240 °C, in open systems at 300 °C, regioselectivity under acceptorless dehydrogenation conditions is consistently low. In this work, complexes [(≡SiO-tBu4POCOP)Ir(CO)] (1) and [(≡SiO-iPr4PCP)Ir(CO)] (2) were synthesized via immobilization of molecular precursors. These complexes were used for gas-phase butane transfer dehydrogenation using increasingly sterically demanding olefins, resulting in observed selectivities of up to 77%. The results indicate that the active site is conserved upon immobilization.

Authors: Arulanantham Zechariah Jebakumar
Published: August 2020

Clinically “Sinusitis” is described because the condition show up through an inflammatory response of the mucous membrane of the nasal cavity and paranasal sinuses, fluid within the cavity, and / or underlying bone. It is also defined as institution of disorders characterised by using irritation of the mucosa of the nostril and paranasal sinuses lasting for atleast 12 weeks.   Pansinusitis is defined as circumstance wherein irritation of all of the paranasal sinuses takes place, which may be unilateral or bilateral. When one or extra sinuses isn't always worried it's far referred to as restricted disorder. When there's terrific brought infection, it leads to mucosal swelling and apposition, which causes ostial occlusion. This impairs the air flow and drainage of the sinus leading to reduced pO2, multiplied pCO2, improved PH and retained secretions. This environment decreases ciliary motility and bacterial overgrowth ensuing in viscid secretions. Bacterial exotoxins also are launched, further reducing the ciliary activity, resulting in a vicious cycle, which results in sinusitis. Hence, the basic concept in Endoscopic sinus surgical procedure is the upkeep of the everyday ventilation and drainage of sinuses, to help the diseased mucosa to get better and regenerate. There was no specific sex predominance in patients suffering from CRS, Endoscopic sinus surgery improves the quality of life by decreasing the post-operative symptoms score, the post-operative sinonasal outcome in non – atopic patients was better when compared to the atopic associated CRS patients, the post-operative sinonasal outcome in patients with limited disease in the sinuses was better than in patients with pansinusitis.

Authors: Nikolayev V. A. , Troshin D. I.
Published: August 2020

Introduction.Tosolve the problem of accelerating the construction of roads, improving their quality, it is advisable to use a continuous action unit to form a underlying layer. The main working bodies of this unit are buckets, which cut off the soil layer from below and on the side. At the same time, the bottom knife cuts off the ground layer from below, the right knife on the side, and the console knife partially cuts the top layer of soil from below for the next bucket. In particular, the analysis of interaction with the soil of the right knife of the continuous action unit is of theoretical and practical interest. To do this, the right knife is divided into elements and analyzed the interaction of these elements with the ground. The consistent impact on the soil of many right knives, within the width of the grip of the unit, is replaced by the impact on the ground of one conventional right knife at a distance necessary for the development of one cubic meter of soil. The forces of interaction of the conventional right knife with the ground are called conditional forces.

The method of research.The method for calculating the energy costs during punching the right knife into the ground is shown: on separating the formation of the ground from its body, on overcoming the ground friction on the edge of the blade, on overcoming the ground pressure on the edge of the blade, on accelerating the ground of the blade by means of the axle, on overcoming the ground friction on the shelf, to overcome the ground friction against the outside surface.The total energy costs of interacting with a soil of one cubic meter are derived from the addition of private energy costs. The method of calculating the horizontal longitudinal force needed to move the right knife is given.

Results.On the basis of the methodology developed, energy costs are calculated when introducing the right knife into the ground: on separating the soil from its body, on overcoming the friction of the ground on the edge of the blade, on overcoming the pressure of the ground on the face of the blade, on the acceleration of the ground with a fascia blade, on overcoming the ground friction on the face. The total energy costs of the right knife interact with the soil of one cubic meter. The horizontal long-lived force needed to move the right knife has been determined.

Conclusion.As a result of the calculations: the energy needed to cut the ground with the right knives, more than 71 J/cube. The horizontal longitudinal force needed to move the right knife is 730 N. To determine the total energy spent on cutting the ground by buckets of the unit to remove the top layer of soil from the underlying layer of the road, it is necessary to analyze the interaction with the soil of other elements of the bucket.
Development of model for human factor influence assessment on construction and road machines operation efficiency
Authors: Ovsiannikov V. E. , Vasiliev V. I.
Published: August 2020

Introduction. The human factor and the characteristics of construction and road machine operators, such as experience, work experience, professional skills, skill, etc., have a significant impact on the efficiency of equipment operation. The human factor, on average, is the cause of about a third of the failures of construction and road machines. One of the most effective ways out of this situation is to improve the machines from the point of view of ensuring the compatibility of the elements of the human-machine system. The article considers the issues of the engineering and psychological component of compatibility.

Materials and methods. The method of analysis of hierarchies is used, when solving the problem of identifying the causes of operators’ errors and fuzzy logic, to build a model for assessing the impact of the human factor on the efficiency of construction and road machines.

Results. As a result of a comprehensive assessment of the causes of errors, it was found that the largest combination of criteria is a group of errors associated with the peculiarities of the task being performed, as well as the properties of the information processed by a person. The developed model for assessing the influence of the human factor on the efficiency of machine operation uses risk as an output variable, and input variables a generalized indicator of the complexity of the algorithm and the level of qualification of the machine operator.

Discussion and conclusions. The resulting model allows you to make a primary assessment of the impact of the human factor and maintenance and repair planning, as well as be used in personnel management processes, for example, in terms of sending personnel for training. Further improvement is seen in the development of neurofuzzy anfys models which provide a knowledge base for more effective risk assessment by specific precedents. The structure of the model in terms of input variables for a more correct risk assessment is also possible to be changed.

The Critic of Literary Values of the Islamic Preach Method Compared Between the Idhah al-Nasyiin Ghalayainiâ€™s Book and The â€œLa Tahzanâ€ Aid al-Qarniâ€™s Book
Authors: Burhan Ali , Hidayatullah Agus
Published: August 2020

The Islamic preach is one of the most important means of achieving future generations. The field of this movement does not have every human being, there are certain conditions and controls that the preacher does not spare in order to ensure that he is successful in his preach to study its history and its origins and to learn about its methods, and means. One of the most important means of publishing the preach is writing recently, whether in the form of articles published in newspaper, magazines, or printed books. The first was done by Sheikh Mustafa Al-Ghalayini through newspaper articles and then written in the form of a printed book. The second was carried out by Sheikh Ayd al-Qarni, a Saudi writer whose the most prominent of which is his spectacular book (La Tahzan). The research methodology is about comparing the previous two books by presenting the material contained therein and critiquing it objectively. After this comparison, the researcher discovered that the literary values that affect the success factors in writing preach must be author familiar with theoretical and applied sciences and the need for the writer to observe the laws and controls of writing using a simple, easy to use method supported by clear definite argument, the need for knowledge of the communityâ€™s language, its situation and treatment with it the preach in all honesty, starting with the preach of the self and then moving to the wider community, and the complete focus in the preach. And this does not mean leaving the job of the public institution that deal with the community.

Neste artigo, partimos de elementos da Sociologia da Ciência de Bruno Latour para analisar atores da Educação em Ciências. De acordo com Latour, a Educação em Ciências participa da rede da Ciência no elo da representação pública. Deste modo, professores, livros didáticos, dentre outros membros desta rede (humanos e não-humanos), podem ser compreendidos como parte da própria Ciência, sendo que a Educação em Ciências e as Ciências participam da rede uma da outra. A partir desta perspectiva, catalogamos enunciados retirados de três livros didáticos aprovados no edital do PNLDEM 2018 de acordo com a tipologia proposta por Latour para analisar enunciados de cientistas. Em uma primeira análise qualitativa, buscamos compreender a trajetória ontológica de diferentes interpretações para a radiação eletromagnética no contexto da Física clássica e moderna. Ademais, valemo-nos de uma segunda arguição qualitativa do dictum e do modus destes enunciados, para elucidar os recursos estilísticos utilizados pelos autores de livros didáticos na construção das trajetórias ontológicas de actantes. Nossos resultados demonstraram que, nos três livros analisados, somente a luz tida como onda no contexto clássico atinge a autonomização. Apesar disso, enunciados com alto grau de realidade foram encontrados para interpretações ontológicas antagônicas.
A Physicist View of COVID-19 Airborne Infection through Convective Airflow in Indoor Spaces
Authors: Anchordoqui Luis Alfredo , Chudnovsky Eugene M.
Published: August 2020

General Idea: Naturally produced droplets from humans (such as those produced by breathing, talking, sneezing, and coughing) include several types of cells (e.g., epithelial cells and cells of the immune system), physiological electrolytes contained in mucous and saliva (e.g. Na+, K+, Cl-), as well as, potentially, several infectious agents (e.g. bacteria, fungi, and viruses). In response to the novel coronavirus SARS-CoV-2 epidemic, which has become a major public health issue worldwide, we provide a concise overview of airborne germ transmission as seen from a physics perspective. We also study whether coronavirus aerosols can travel far from the immediate neighbourhood and get airborne with the convective currents developed within confined spaces. Methodology: Methods of fluid dynamics are utilized to analyse the behavior of various-size airborne droplets containing the virus. Study Findings: We show that existing vortices in the air can make a location far away from the source of the virus be more dangerous than a nearby (e.g., 6 feet away) location. Practical Implications: Our study reveals that it seems reasonable to adopt additional infection-control measures to the recommended 6 feet social distancing. We provide a recommendation that could help to slow down the spread of the virus.

Published: August 2020

Social media is a means to communicate and exchange information between people, and Twitter is one of them. But the information disseminated is not entirely true, but there is some news that is not in accordance with the truth or often called hoaxes. There have been many cases of spreading hoaxes that cause concern and often harm a particular individual or group. So in this research, the authors build a system to identify hoax news on social media Twitter using the Decision Tree C4.5 classification method to the 50,610 tweet data. What distinguishes this research from some researches before is the existence of several test scenarios, classification only, classification using weighting feature, and also classification using weighting feature and feature selection. The weighting method used is TF-IDF, and the feature selection uses Information Gain. The features used are also generated using n-grams consisting of unigram, bigram, and also trigrams. The final results show that the classification test that uses weighting feature and feature selection produces the best accuracy of 72.91% with a ratio of 90% training data and 10% test data (90:10) and the number of features used is 5000 in unigram features.

Informasi curah hujan bulanan sangat diperlukan dalam perencanaan irigasi dan bangunan air, perencanaan infrastruktur, pertanian, transportasi dan juga telekomunikasi. Dengan adanya perbedaan sifat curah hujan bulanan setiap tahunnya, kita tidak dapat memprediksi sifat curah hujan yang akan terjadi pada tahun berikutnya. Backpropagation adalah salah satu metode dalam Jaringan Syaraf Tiruan (JST) yang digunakan untuk prediksi. Jaringan syaraf tiruan (JST) merupakan salah satu sistem pemrosesan informasi yang meniru cara kerja otak manusia. JST mempunyai kemampuan untuk memberikan keputusan terhadap data yang telah dipelajari sebelumnya. Pada penelitian ini, JST Backpropagation menggunakan 3 neuron  berupa variabel input yaitu data curah hujan bulanan 3 tahun sebelumnya dengan target curah hujan bulanan tahun berikutnya, 1 lapisan tersembunyi dengan 3 neuron, Pada pengujia ini ditentukan nilai parameter learning rate (α) dimulai dari 0.01, 0.03, 0.05, 0.09 dan 0.1, sedangkan batasan epoch yang digunakan dimulai epoch 1000, epoch 1500 dan epoch 2000, dan nilai ambang batas (threshold) 0.0001, 0.00001 dan 0.000001, dalam proses pembelajaran dilakukan 5 kali pengujian terhadap data curah hujan bulanan. Akurasi MSE tekecil yang didapat pada pengujian paramater ini yaitu 0,005 terdapat pada learning rate 0,1 dengan epoch ke 2000, dari semua pengujian parameter yang dilakukan memiliki hasil prediksi yang sama yaitu dari 12 bulan terdapat 9 bulan yang sesuai dengan target dan 3 bulan yang tidak sesuai target terhadap data curah hujan bulanan tahun 2017. Sehingga kelayakan sistem yang didapatkan dari pengujian tersebut adalah 91,67%.

Fil Sûresi İle İlgili Modern Yorumların Kritiği
Authors: ÖZEL Recep Orhan
Published: August 2020

Allah’ın tabiatın olağan akışına müdahil oluşu, Kur’ân’da çeşitli vesilelerle anlatılan ve hemen hemen bütün peygamberlerin hayatında yer alan bir husustur. Bilinen doğa kurallarının aşımı anlamına gelen mucizevi olaylarla kimi zaman peygamberler desteklenmiş, kimi zaman da kavimler helak edilip cezalan-dırılmıştır. Özellikle Kur’ân kıssalarında bu hususun sıkça vurgulandığı görülmektedir. Yaratıcının doğa-da sıra dışı olarak gerçekleştirdiği mucizeler peygamberlerin sadâkati ve Allah’ın yüce kudreti için bir delil anlamı taşımaktadır. Bununla beraber bazı ilim adamlarınca Allah’ın tabiata koyduğu kurallarda yasa kırıcı bir fiilde bulunmadığı iddia edilmiştir. Son dönemlerde pozitivist yaklaşımların bilim dünyasına hâkim olmaya başlamasından itibaren de benzeri yorumlarda artış gözlenmiştir. Olaylara determinist perspektif-le bakanlar, doğa yasalarını ihlal anlamına geldiğini düşündükleri hârikulâde hâdiseleri çeşitli yollarla tevil etme gayreti içine girmiştir. Ancak bu yönde yoğun çabalar harcanırken Kur’ân’ı doğru anlama yolundaki usul ve esaslar çoğu kere terkedilmiş, Kur’ân’ın açık ve net beyanları ön yargılara ve keyfi uygulamalara tabi kılınarak yorumlanmıştır. Modern dönemde bu tür yaklaşımların bir örneğini de Fil Suresi tefsiri bağlamında görülmüştür. Bu çalışmada Fil Suresi çerçevesinde üretilen çeşitli modern yorumlara yer veri-lecek ve bunların kritikleri yapılacaktır.

Data lakes are an emerging storage paradigm that promotes data availability over integration. A prime example are repositories of Open Data which show great promise for transparent data science. Due to the lack of proper integration, Data Lakes may not have a common consistent schema and traditional data management techniques fall short with these repositories. Much recent research has tried to address the new challenges associated with these data lakes. Researchers in this area are mainly interested in the structural properties of the data for developing new algorithms, yet typical Open Data portals offer limited functionality in that respect and instead focus on data semantics.We propose Loch Prospector, a visualization to assist data management researchers in exploring and understanding the most crucial structural aspects of Open Data — in particular, metadata attributes — and the associated task abstraction for their work. Our visualization enables researchers to navigate the contents of data lakes effectively and easily accomplish what were previously laborious tasks.

Introduction: Coronavirus disease 2019 (COVID-19) can present as a range of symptoms, from mild to critical; lower pulmonary involvement, including pneumonia, is often associated with severe and critical cases. Understanding the baseline characteristics of patients hospitalized with COVID-19 illness is essential for effectively targeting clinical care and allocating resources. This study aimed to describe baseline demographics and clinical characteristics of US patients hospitalized with COVID-19 and pulmonary involvement.Methods: US patients with COVID-19 and pulmonary involvement during an inpatient admission from December 1, 2019, to May 20, 2020, were identified using the IBM Explorys® electronic health records database. Baseline (up to 12 months prior to first COVID-19 hospitalization) demographics and clinical characteristics, and preadmission (14 days to 1 day prior to admission) pulmonary diagnoses were assessed. Patients were stratified by sex, age, race, and geographic region.Results: Overall, 3471 US patients hospitalized with COVID-19 and pulmonary involvement were included. The mean (SD) age was 63.5 (16.3) years; 51.2% of patients were female, 55.0% African American, 81.6% from the South, and 16.8% from the Midwest. The most common comorbidities included hypertension (27.7%), diabetes (17.3%), hyperlipidemia (16.3%), and obesity (9.7%). Cough (27.3%) and dyspnea (15.2%) were the most common preadmission pulmonary symptoms. African American patients were younger (mean [SD], 62.5 [15.4] vs 67.8 [6.2]) with higher mean (SD) body mass index (33.66 [9.46] vs 30.42 [7.86]) and prevalence of diabetes (19.8% vs 16.7%) and lower prevalence of chronic obstructive pulmonary disease (5.6% vs 8.2%) and smoking/tobacco use (28.1% vs 37.2%) than White patients.Conclusions: Among US patients primarily from the South and Midwest hospitalized with COVID-19 and pulmonary involvement, the most common comorbidities were hypertension, diabetes, hyperlipidemia, and obesity. Differences observed between African American and White patients should be considered in context of the complex factors underlying racial disparities in COVID-19.
