Published: November 2019

Innovations in batteries take years to formulate, requiring extensive experimentation during the design and optimization phases. We approach the design of a battery electrolyte as a black-box optimization problem. We report here the discovery of a novel battery electrolyte by a robotic electrolyte experiment guided by machine-learning software. Motivated by the recent trend toward super-concentrated aqueous electrolytes for high-performance batteries, we utilize Dragonfly - a Bayesian machine-learning software package - to search mixtures of commonly used lithium and sodium salts for super-concentrated aqueous electrolytes with wide electrochemical stability windows. Dragonfly autonomously managed the robotic test-stand, recommending electrolyte designs to test and receiving experimental feed- back in real time. Within 40 hours of continuous experimentation, Dragonfly discovered a novel, high-performing aqueous sodium electrolyte that a human-guided design process may have missed. This result demonstrates the possibility of integrating robotics with machine-learning to rapidly and autonomously discover novel battery materials.
A Method for Accurately Predicting Solvation Structure
Authors: Duignan Timothy , Schenter Gregory K. , Mundy Christopher J. , Zhao Xiu Song
Published: November 2019

Accurately predicting the molecular structure of solutions is a fundamental scientific challenge. Using quantum mechanical density functional theory (DFT) to make these predictions is hindered by significant variation depending on which DFT functional is used. Here, we present a simple metric that can determine the reliability of a DFT functional for predicting solvation structure. We then show that including a simple interaction term to correct this metric leads to quantitative agreement with experimental measurements of liquid structure. We demonstrate the utility of this method by using it to accurately describe the hydration structure around the Na+ and K+ ions as well as the structural properties of pure water with a computationally cheap functional.
Scalable Approach to High Coverages on Oxides via Iterative Training of a Machine-Learning Algorithm
Authors: Medford Andrew , Yang Shengchun , Liu Fuzhu
Published: November 2019

Understanding the interaction of multiple types of adsorbate molecules on solid surfaces is crucial to establishing the stability of catalysts under various chemical environments. Computational studies on the high coverage and mixed coverages of reaction intermediates are still challenging, especially for transition-metal compounds. In this work, we present a framework to predict differential adsorption energies and identify low-energy structures under high- and mixed-adsorbate coverages on oxide materials. The approach uses Gaussian process machine-learning models with quantified uncertainty in conjunction with an iterative training algorithm to actively identify the training set. The framework is demonstrated for the mixed adsorption of CHx, NHx and OHx species on the oxygen vacancy and pristine rutile TiO2(110) surface sites. The results indicate that the proposed algorithm is highly efficient at identifying the most valuable training data, and is able to predict differential adsorption energies with a mean absolute error of ~0.3 eV based on <25% of the total DFT data. The algorithm is also used to identify 76% of the low-energy structures based on <30% of the total DFT data, enabling construction of surface phase diagrams that account for high and mixed coverage as a function of the chemical potential of C, H, O, and N. Furthermore, the computational scaling indicates the algorithm scales nearly linearly (N1.12) as the number of adsorbates increases. This framework can be directly extended to metals, metal oxides, and other materials, providing a practical route toward the investigation of the behavior of catalysts under high-coverage conditions.
Molecular Engineering Strategies for Symmetric Aqueous Organic Redox Flow Batteries
Authors: Fornari Rocco Peter , Mesta Murat , Hjelm Johan , Vegge Tejs , de Silva Piotr
Published: November 2019

Symmetric aqueous organic redox flow batteries (RFBs) are potentially a cheap, durable and safe energy storage technology. Unlike normal asymmetric flow batteries, they are based on electrolytes that exist in at least three oxidation states and can undergo a minimum of two distinct redox processes. We compute the redox potentials of selected electrolytes intending to understand how the interaction between the redox units affects the potentials. We find that electronic interaction between redox units and intramolecular hydrogen bonding can both be exploited to tune the difference between the redox potentials, i.e. the theoretical voltage of the battery. The redox potentials can be further fine-tuned in either direction by adding substituents. Starting from these observations we formulate a set of rules which will help finding ideal candidates for symmetric RFBs.

Politik hukum hadir di titik perjumpaan antara realisme hidup dengan tuntutan idealisme. Politik hukum menyangkut sebuah cita-cita atau harapan, maka terdapat visi hukum yang ditetapkan terlebih dahulu yang kemudian bentuk dan isi hukum dibangun untuk mewujudkan visi tersebut. Urgensi keberadaan peradilan administrasi dalam mewujudkan Negara hukum mendorong pemerintah untuk membentuk sistem hukum dibidang peradilan administrasi, yakni melalui pembentukan Undang-Undang Nomor 5 Tahun 1986 Tentang Peradilan Tata Usaha Negara, yang merupakan fondasi bagi pembentukan Peradilan Tata Usaha Negara di Indonesia. Pada penjelasan Undang-Undang Nomor 5 Tahun 1986 disebutkan bahwa Peradilan Tata Usaha Negara diadakan dalam rangka memberikan perlindungan kepada rakyat percari keadilan, yang merasa dirinya dirugikan akibat suatu Keputusan Tata Usaha Negara. Secara prinsip, suatu negara diharapkan dapat memberikan perlindungan terhadap hak-hak asasi manusia warga negaranya.

Published: November 2019

Purpose: This study aims to investigate the relationship between different performance appraisal methods and employees’ performance in a private hospital in South Lebanon. Three main appraisal methods were selected for this study including traditional appraisal, self-appraisal and customer appraisal methods. In addition, the employees’ performance was measured at different levels including task, adaptive and contextual performance.

Design: Based on a quantitative approach and using self-administered questionnaires, primary data was collected randomly from 125 employees of the target hospital.

Findings: The results obtained showed that employees are generally performing in an adequate level and they are pleased with the current applied performance appraisal systems at this hospital and especially at the level of customer appraisal methods.

Originality: This study showed how private hospital in Lebanon use performance appraisal systems in managing their human resources through measuring employees’ performance, motivating them and most commonly, making critical administrative decisions related to training and development or even rewarding and coercive actions.

Future suggestions: Future studies are recommended to expand the research geographically and comprise variety of hospitals in terms of size or type. Also, studying different performance appraisal systems would enrich the literature especially at the empirical level.

KONDISI KUALITAS AIR BAKU INSTALASI NGAGEL PERUSAHAN DAERAH AIR MINUM (PDAM) KOTA SURABAYA
Authors: Said Nusa Idaman , Hartaja Dinda Rita Krishumartani
Published: November 2019

Saat ini PDAM Kota Surabaya mempunyai kapasitas pengolahan total sekitar 10.500 liter per detik yang terdiri dari beberapa instalasi yaitu IPA Karang Pilang I, IPA Karang Pilang II, IPA Karang Pilang III, IPA Ngagel I, IPA Ngagel II dan IPA Ngagel III. Kapasitas total instalasi pengolahan air Ngagel I sebesar 1800 liter per detik, dan Ngagel II sebesar 1000 liter per detik, sedangkan kapasitas instalsi pengolahan air Ngagel III sebesar 1.750 liter per detik. Air baku yang digunakan adalah air sungai yang diambil dari sungai Surabaya. Seiring pesatnya pertumbuhan pemukiman dan perkembangan sektor industri, mengakibatkan semakin tingginya tingkat pencemaran Sungai  Surabaya. Hal tersebut berpengaruh pada menurunnya kualitas air oleh polutan khususnya polutan organik dari limbah domestik maupun limbah industri. Akibatnya  Sungai Surabaya memiliki kualitas air baku yang kurang memenuhi ketentuan baku mutu yang dipersyaratkan sebagai air baku air minum. Untuk mengetahui kondisi tingkat pencemaran di dalam air sungai salah satu metoda yang banyak digunakan adalah dengan menentukan indeks pencemaran (IP). Penelitian ini bertujuan untuk mengetahui kondisi kualitas air baku di intake Ngagel serta menentukan tingkat pencemaran dengan menggunakan metoda indeks pencemaran. Penelitian ini dilakukan dengan menggunakan data sampling kualitas air di intake Ngagel yang dilakukan oleh PDAM dari tahun 2015 sampai dengan tahun 2017. Dengan menggunakan perhitungan Indeks Pencemaran (IP), dapat diketahui bahwa tingkat pencemaran air di Intake Ngagel tahun 2015 - 2017 tergolong dalam pencemaran sedang hingga pencemaran berat. Parameter yang paling potensial menyebabkan tingkat pencemaran tersebut adalah COD, BOD, Zat Organik serta konsentrasi oksigen terlarut (DO). Konsentrasi polutan organik dalam sungai tersebut telah melebihi baku mutu air kelas I berdasarkan PP No 82 tahun 2001, yakni untuk peruntukan air baku air minum. Dari tahun 2015 hingga 2016, terjadi peningkatan tingkat pencemaran, tetapi pada tahun 2017 tingkat cemaran cenderung sedikit mengalami penurunan dibandingkan dengan 2 (dua) tahun sebelumnya. Salah satu alternatif untuk meningkatkan kualitas air baku di Intake Ngagel yang yang diambil dari Sungai Surabaya adalah dengan menggunakan sistem biofilter.Dengan proses biofiltrasi konsentrasi polutan organik, amoniak, detergen, padatan tersuspensi, zat besi, mangan akan dapat diturunkan sehingga konsumsi bahan kimia khususnya koagulan dan khlor untuk pengolahan air minum menjadi berkurang. Dengan demikian biaya produksi pengolahan air juga akan menjadi berkurang. Dengan semakin rendahnya konsentrasi amoniak di dalam air baku, maka penggunaan khor juga akan semakin sedikit, sehingga kemungkinan terjadinya senyawa hasil samping khlorinasi misalnya trihalometan juga semakin kecil.Kata Kunci : Biofilter, IPA, Kualitas Air

Kabupaten Trenggalek, Provinsi Jawa Timur merupakan daerah yamg memiliki potensi kekayaan tambang yang tersebar di beberapa lokasi yang belum dikembangkan secara optimal. Menurut data Dinas Koperasi, Industri, Perdagangan, Pertambangan dan Energi Kabupaten Trenggalek menunjukkan bahwa daerah di Kecamatan Gandusari mempunyai potensi tambang mangan sekitar 1,03 juta ton. Desa Melis merupakan salah satu desa yang terletak di Kecamatan Gandusari, Kabupaten Trenggalek, di desa ini sumber air penduduk mengandung mangan (Mn) cukup tinggi. Mengkonsumsi air yang mengandung mangan tinggi dapat mengganggu kesehatan. Salah satu cara untuk menurunkan kadar mangan tinggi dalam air adalah melakukan pengolahan air terlebih dahulu sebelum dikonsumsi, untuk itu Pusat Teknologi Lingkungan BPPT telah membangun pilot plan teknologi pengolahan air siap minum (Arsinum) di Pondok Pesantren Ummul Quro, Desa Melis, Kecamatan Gandusari, Kabupaten Trenggalek. Proses pengolahan air siap minum ini dapat mengurangi kadar mangan dan memenuhi persyaratan kualitas air minum yang dikeluarkan oleh Kementerian Kesehatan RI Nomor 492/MENKES/PER/IV/2010. Kata kunci : Sumber air, mangan, pengolahan air siap minum (Arsinum)
PROSES PEMUTIHAN KAOLIN CICALENGKA UNTUK PELAPIS KERTAS
Authors: Aliwarga Lienda
Published: November 2019

Rata-rata bahan baku kaolin di Indonesia masih mempunyai derajat keputihan yang rendah padahal kaolin harus mempunyai derajat keputihan yang tinggi (>83%) untuk dapat digunakan sebagai pelapis dalam industri kertas. Untuk meningkatkan derajat keputihan dari bahan baku kaolin tersebut, proses pemutihan perlu dilakukan. Proses pemutihan kaolin telah banyak dilakukan oleh beberapa peneliti dengan menggunakan pemutih yang berbeda-beda. Warna kuning kecokelatan pada kaolin yang menurunkan derajat keputihan kaolin disebabkan oleh kandungan besi (III) oksida dalam kaolin. Pada proses pemutihan, terjadi reduksi besi (III) oksida menjadi besi (II) oksida yang lebih mudah larut dalam air sehingga lebih mudah dipisahkan dari padatan kaolin. Pada penelitian ini, pemutihan kaolin menggunakan Na2S2O4 dan EDTA sebagai pemutih. Penelitian ini bertujuan untuk melihat pengaruh variabel operasi yaitu pHÂ  dan temperatur terhadap derajat keputihan kaolin pada proses pemutihan menggunakan kedua pemutih tersebut. Hasil percobaan menunjukkan proses pemutihan menggunakan Na2S2O4 dan EDTA dapat meningkatkan derajat keputihan kaolin sehingga memenuhi spesifikasi untuk pelapis kertas pada beberapa kondisi operasi. Proses pemutihan berhasil meningkatkan derajat keputihan kaolin hingga mencapai 85,54% pada pHÂ  12 dan temperatur 70oC.

Creencias de padres haitianos: Rol de la escuela en la inclusión social de sus hijos/as
Authors: Fierro Retamal Carla
Published: November 2019

Desde el último año, el gobierno de Chile ha encabezado un proceso de modificación en la política educacional entre Chile y Haití. Esto último es una condición interviniente de inclusión social para los mismos haitianos que llegan al país.En este contexto, se realizó una investigación que describe y analiza las creencias de padres haitianos de la comuna de Quilicura, respecto del rol de la escuela en los procesos de inclusión social de sus hijos e hijas. Los principales resultados dan cuenta de una diversidad cultural que existe hoy en la escuela, en donde las creencias de los padres haitianos no son consideradas. Además de prevalecer en la escuela el enfoque de integración social más que el de inclusión social, lo cual hace que niños y niñas coarten su proceso de inclusión social efectiva en el establecimiento, ya que no tienen el apoyo ni las herramientas para desarrollarlo correctamente.
La acción social profesional del Trabajo Social en el área de justicia juvenil en Chile
Authors: Aedo Poblete Karina
Published: November 2019

El año 2007 se implementa en Chile la Ley de Responsabilidad Penal Adolescente, llevando a cabo distintos programas centrados en el control social, los cuales han sido ejercidos históricamente por trabajadores sociales. Esto ha llevado a repensar la acción profesional, en la que se evidencian distintas tensiones; por una parte, un sistema enfocado en que los adolescentes infractores de ley lleven a cabo sus medidas y sanciones respecto de los delitos cometidos y que frente a esto logren la reinserción social, pero, por otra, la invisibilización de un sistema neoliberal, altamente desigual y violento, en el que se responsabiliza únicamente a los jóvenes y a sus familias. Es decir, un sistema que vulnera y pasa por alto todo tipo de derecho, que a través de políticas públicas de reinserción social nos hace creer que encuentra la solución respecto de las mismas problemáticas que este ha creado desde el surgimiento de la cuestión social.
Posibilidades dialógicas de la visualidad poética en Calamina de Gladys González y Puentes de Alicia Genovese
Authors: Moraga Garcí­a Fernanda
Published: November 2019

El objetivo principal de este artí­culo es explorar las interrelaciones poéticas entre imagen, lugar e intimidad como polí­ticas dialógicas en el libro Calamina de la poeta chilena Gladys González (1981) y en el poemario Puentes, de la poeta argentina Alicia Genovese (1953). Aunque se trata de propuestas diferenciadas en sus distintos niveles de factura, pensamos que existe una zona fronteriza entre ambas que permite reflexionar en torno a las posibilidades de lo visual en la construcción de la imagen poética y también sobre el lugar de la enunciación como polí­tica dialógica. La relación entre imagen poética y lugar de enunciación se realiza a partir de las nociones de dilogí­a, alteridad e imagen poética. El artí­culo sostiene que el desenvolvimiento de una poética más visual en ambos poemarios, obedece al doble imaginario simbólico que tiene la articulación entre mirada y poesí­a. Esto favorece un "efecto visual" de la escritura que traspasa las fronteras entre la imagen, el lugar y la intimidad de las enunciaciones poéticas, provocando la desestabilización de patrimonios espaciales.
Treatment of White Coat HYpertension in the Very Elderly Trial (HYVET 2) - Feasibility of a Randomized Controlled Trial (Study Protocol)

Published: November 2019

The results of HYpertension in the Very Elderly Trial (HYVET) were crucial in providing evidence of benefit of the treatment of hypertension in those 80 years or older. Following a subsequent sub study analysis of the HYVET data there is a suggestion that 50% of patients in the main study had White Coat Hypertension (WCH), defined as clinic BP readings >140/90 mmHg and ambulatory BP readings <135/85 mmHg. Currently, definitive evidence in support of treatment for such individuals is not available. HYVET 2 has been designed in order to assess the feasibility of conducting a randomized controlled trial which might determine whether the treatment of WCH in the very elderly is clinically beneficial. One hundred participants aged ≥75 years diagnosed with WCH will be recruited from General Practices (GPs) in UK. Randomization will be 1:1 to a treatment arm (indapamide and perindopril) and control arm (no treatment) and follow up will be for 52 weeks. HYVET 2 will report on feasibility outcomes including participant recruitment, adherence and withdrawal rates, willingness of GPs to recruit and randomize patients and the frequency of a composite of cardiovascular events. Simple descriptive statistics will be presented.
Quality of Reporting in Human Aortic Tissue Research — A Systematic Review
Authors: Chim Ya-Hua , Caamaño-Gutiérrez Eva , Birla Rashmi , Madine Jillian , Field Mark , Akhtar Riaz , Davies Hannah Angharad
Published: November 2019

Ex vivo human tissue is a valuable research resource. However, if vital methodological information such as anatomical location, tissue processing procedures, or donor characteristics are not reported in scientific literature to a high standard, studies utilising ex vivo human tissue can be difficult to replicate. Furthermore, data analysis and interpretation based on these studies can be challenging. In this systematic review, we focus on the reported use of human aortic tissue in research. The human aorta is a complex tissue, with embryological, biochemical and biomechanical variations along its length, which alter with age, and differ between genders and ethnicities. The aorta therefore serves as an excellent case study for examining the importance of high quality and robust reporting of methodology when utilising human tissue samples, for reliable interpretation and reproducibility. In this systematic review, we sought to critically analyse scientific papers published between 1980 and 2017 which utilised human aortic tissue to determine whether the methodological information provided would be sufficient for replication, comparison with other studies and interpretation. Eight databases (Springerlink, ScienceDirect, PMC, PLoS, JSTOR, Pubmed, Web of Science, Scopus) were mined for articles that contained the search term ‘human aortic tissue’ from January 1980 to August 2017. Following review, 143 full-text articles were selected, data extracted, tabulated and analysed. The review highlighted several areas where reporting of human aortic tissue use was insufficient for replication and thorough data interpretation. The use of control tissue was often poorly explained and in many cases, omitted completely. Sample size was largely difficult to calculate and 30% of studies did not provide this information. Age/gender information was absent in 30% of studies. Tissue storage and handling information was present in 78%, and 75% of studies gave information about statistical analyses but few gave enough information for replication. Overall the quality of reporting in many studies was deemed to be of a low standard for replication and reliable interpretation of the reported findings. Here we propose five simple recommendations for the reporting of human tissue with the primary aim of improving reproducibility and transparency in the sector, avoiding bias and maximising output.

Published: November 2019

Canine dietary requirements and nutritional habits have changed since dogs were first domesticated. Therefore, periodontal diseases (PD) are the most common problem affecting dogs in all age groups. The aim of this study was to determine the relationship between diet type and oral health of dogs examined in veterinary clinic. To reveal the association between nutrition and oral health, two trials were held at the same veterinary practice in Istanbul-Turkey during 2016 and 2018. For the first trial; data coming from 100 patients examined, pre-determined questionnaire forms were filled by the owners. For the second trial, 106 dogs that came to the clinic during 2018 were examined by veterinarians for oral health and a form was filled out for each patients. It was determined that most of dogs (Trial 1: 82.0%; Trial 2: 71.7%) were fed dry food and also most of dogs older than 4 years had oral health problems (P<0.05).  No statistically significant association was determined between oral health and type of diet, gender, and home dental care in Trial 1. Also, it was observed that oral problems in dogs fed once a day were significantly fewer than those in dogs fed two or more times a day (P<0.05). However, in Trial 2, statistically significant association was determined between PD and age, type of diet, oral health (P<0.05).   These results suggest that oral health problems are more likely to be seen in older animals and feeding dogs with dry food decreases the occurrence of PD.

Selection of cotton is carried out mainly on phenotypic indicators and most often the varieties obtained are either not sufficiently resistant to various diseases or their fiber is low standard of technical. The disease of cotton with the defeat of Verticillium dahliae Klebhan is mainly expressed by a profound change in the physiological and biochemical processes in plants. Peroxidase, polyphenol oxidase, phenylalanine ammonia lyase are the main enzymes of cotton phytoimmunity. NIISSVAH employees allocated and transferred to the biochemical analysis of the 9 cotton samples to the Institute of Bioorganic Chemistry AnRUz. As a result of research, the seeds were tested in order to study the activity of enzymes of chitin-specific peroxidase, polyphenol oxidase, phenylalanine ammonia lyase. The seedlings of hybrid combinations of F1 cotton were used to select breeding material with high resistance to Verticillium dahliae Klebhan. It was established that among the studied samples resistant to affect by the pathogen V.dahliae the following should be attributed combinations of first-generation hybrids - Sultan × Namangan 34; Andijan-35 × Namangan 34; F1 Namangan 34 × Sultan; F1 Namangan 34 × Gulbahor-2; F1 Namangan 34 × Andijan-35; F1 Namangan 34 × Andijan-16; F1 Gulbahor-2 × Sultan.

Authors: Chursinov Yu. A. , Kovaleva E. S.
Published: November 2019

The intensification of the germination of seed material of different crops is a promising direction for improving agricultural technologies. The use of safe and highly effective germination activators allows to accelerate the biological processes of plant growth, to reveal the productivity potential inherent in each variety. Increasing the rates, such as energy and germination, significantly increase crop yields.

The scientific work objective was to expand the range of universal crop growth stimulants that would be able to provide uniform germination, increased energy and the ability to germinate seed material, as well as shorten the period from sowing to seedlings. The use of organic acids is proposed: nicotinic (3-pyridinecarboxylic), folic (pteroylglutamic), succinic (butanedioic) with a given concentration of active substances. This technological solution allows to intensify the processes of seed germination of various crops. The presented organic acids and their solutions are recommended to be used in pre-sowing treatment of seeds by spraying or one-time soaking in aqueous solutions of these acids. The studies were carried out on the base of the scientific and production laboratory for determining the quality of grain and grain products of the Dnepropetrovsk State Agrarian and Economic University. The studied growth stimulants have established themselves as substances with a stable effect and low toxicity. They can be used both in crop production in pre-sowing seed treatment in order to intensify growth, and for the production of germinated grain in the production technologies of alcohol, beer, mono-and polysalt malt extracts in order to obtain malt.
