West syndrome - epileptic encephalopathy at early infancy
Authors: Malavika Gopi  , Akshaya Suresh  , Anandu H  , Roshni P R  , Mamatha M R  , Vinayan K P
Published: January 2021

West syndrome (WS), synonymously infantile spasm or epileptic spasm, is a rare type of epileptic encephalopathy occurring at early infancy that exists with variable life expectancy. It is the most common form of epileptic encephalopathy. WS presents with spasms marked by extensor or mixed movements with distinct electroencephalogram (EEG) pattern of hypsarrhythmia, flexor and psychomotor arrest. Children with west syndrome always depict abnormal EEG, but sometimes the abnormality is seen only during sleep. The incidence of infantile spasms is found closer to 1 in 2,000 children, that typically begins between 2-12 months of age and peaks between 4-8 months of age. It is observed in otherwise healthy infants and also among infants with abnormal cognitive development. If this spasm happens in older subjects, they are preferably called "epileptic spasms" rather than infantile spasms. The goal for treatment of infantile spasms is to have complete control of spasms. Hormonal therapy with ACTH or vigabatrin is the mainstay of treatment. In spite of the development of new antiepileptic drugs (AEDs), about 35-40% of cases are drug-resistant. Children affected with the west syndrome can be cured, but a successful therapy often depends on the timely diagnosis. This case report is one evidence highlighting the treatment strategy for the west syndrome, and this could be useful for any further study regarding this topic.

Published: January 2021

A novel scaffold of 4-anilino quinazoline derivatives was designed on the basis of known inhibitor of quinazoline based drugs. The designed derivatives were synthesized using optimized reaction condition. Their structures were confirmed by FT-IR, 1H-NMR, 13C-NMR and Mass spectral data. The structures of synthesized compounds were subjected to in silico  molecular docking using AutoDock software against the target Poly (ADP-ribose) polymerase-1 (PARP-1) enzyme. The compounds were evaluated for their in vitro cytotoxic activity against Daltons Lymphocyte Ascites (DLA) Cell lines. Molecular docking study of the newly synthesized compounds showed good binding mode in the active site of PARP-1. The docking results were compared with the standard drug Doxorubicin. Doxorubicin showed binding energy of -8.94 kcal/mol and formed one hydrogen bond with Asn767 with a distance of 1.98 Å. Compound SMOQ2 showed the least binding energy, i.e., 11.87kcal/mol and formed one hydrogen bond with Arg 878 with a distance of 1.895.A° Compound DMUQ5 showed binding energy of -11.42 kcal/mol and produced two hydrogen bonds with Arg 878 and Asn 767. Among the synthesized compounds, compounds SMOQ2 and DMUQ5 showed significant binding affinity compared to the standard drug Doxorubicin. The in vitro cytotoxic evaluation indicated that compounds SMOQ2 and DMUQ5 showed significant cytotoxic activity against Daltons Lymphoma Ascites cell line.
Modeling and docking studies of Keratinase from Bacillus Tequilensis MBR 25 against CYP51A of Aspergillus ৒lavus for inhibition: Insilico studies
Authors: Bethala Ramya  , Pandu Brahmaji Rao
Published: January 2021

Aspergillus flavus, which are common types of 'weedy' molds that are typically distributed in nature, are formed by aflatoxins. The existence of these molds does not always show that the aflatoxin levels are dangerous but shows an important danger. The molds may colonize and contaminate food before harvest or during storage, especially after prolonged exposure to high moisture or too stressful conditions such as dryness. Using 5EQB as a template for Modeler 9v7, a three-dimensional model of CYP51A from Aspergillus flavus was developed. After energy reduction, the structures of CYP51A 3D were compared with the prototype, and the final models were obtained using molecular mechanics and molecular dynamic methods. For flexible docking tests, a highly expressed CYP51A with keratinase from Bacillus tequilensis MBR 25 was used. The results showed that the LEU126, ALA153 and ILE165 binding steps of CYP51A are important determinant residues because hydrogen is closely linked to these compounds. These interactions with hydrogen bonding play an important role in stabilizing the complex.

EIGENVALUE METHOD AND LINEARIZATION FOR THE STEADY STATE STABILITY ANALYSIS OF JAMSHORO THERMAL POWER PLANT (JTPP)
Authors: Ali Shahani Zulfiqar
Published: January 2021

Electrical power system without interruption is the need of every consumer. Therefore, supplying electrical power which must be efficient, reliable and secure from any disturbance is the priority of power supply companies. But, due to changes in weather conditions and continuous load variations, small disturbances arise which may lead to severe disturbance. All electrical generating stations are interconnected, so a failure in any one unit can affect other generating units, therefore analysis is compulsory to solve the problem in the least time, and avoid a further big loss. Analysis of steady-state stability or transient stability plays a key role in a power system which helps to understand the behavior of a dynamic system. The stability problem is concerned with the behavior of the generating station when the system puts on either small or large disturbance. In this work, the steady-state stability (SSS) analysis of the Jamshoro thermal power plant (JTPP) is analyzed by using the eigenvalue method and linearization technique at four different reheat gain values. We develop a nonlinear mathematical model of JTPP and discuss its linearized form, and examine the behavior of the system stability using eigenvalues. The eigenvalue method analyzes the behavior of synchronous machine when system load varies continually. Numerical values of eigenvalues consist of either real part or real as well as imaginary parts. These eigenvalues help to understand the stability of the system, as to whether the system is stable or not.

Проведена характеризация с помощью рентгеновской дифракции, просвечивающей электронной микроскопии и рентгеновской фотоэлектронной спектроскопии перовскитоподобного сложного оксида La0.5Ca0.5Mn0.5Co0.5O3±δ, синтезированного по методу Пекини. Впервые выполнены in situ исследования структурных превращений данного соединения в средах с различным парциальным давлением кислорода и в среде с водородом. Показана нестабильность твердого раствора в среде с низким парциальным давлением кислорода. Продемонстрировано, что на структурное состояние образца оказывает влияние не только наличие/отсутствие кислорода в среде, но и скорость охлаждения образца. Методами рентгеновской дифракции и термического анализа обнаружен полиморфный переход перовскита из орторомбической симметрии в кубическую при 600 °C, связанный с потерей кислорода веществом. При восстановлении образца водородом обнаружено появление двух перовскитоподобных фаз с псевдокубической и орторомбической симметрией, которое может быть связано с неравномерным формированием вакансий в твердом растворе и изменением степеней окисления катионов кобальта и марганца. Показана возможность частичной регенерации исходной структуры из восстановленного в Н2 сложного оксида.

Background: Breast cancer is the leading cause of death in women globally. The present study aimed to determine the prevalence of different mammographic density of breast parenchyma along with the association with the molecular subtype of breast cancer.

Methodology: The present cross-sectional study was conducted among breast cancer females age 40 and above. The study participants' demographic and clinical data, such as age, sex, menstrual status, gravida, parity, and lactation, were collected using a standard questionnaire. The anthropometric parameters were taken by using the standard techniques. Breast physical examination, mammography, and ultrasound were done. The ultrasound did the breast tumor biopsy -guided techniques and histopathology, and immunohistochemistry was used to identify the molecular subtype of breast cancer. The univariate and multivariate statistic was performed on SPSS version 20.0.

Results: Most of the patients<50 years were human epidermal growth factor receptor (HER2), estrogen receptor (ER), progesterone receptor (PR) positive, and are overweight too. Similar findings were noted among lactating and multigravida patients. The Grade I tumor and dense breast patients were 100% with HER2 negative and ER, PR positive. Most heterogeneous dense and fibroglandular containing breast patients were ER, PR positive. There is a significant correlation between BMI, microcalcification, and HER2 positive. Most of the triple Negative and Luminal-B were heterogeneous dense.

Conclusion: In conclusion, a significant association between the mammographic density parameters and molecular breast cancer subtype, particularly Luminal-A and luminal B, was seen. The ER, PR, and HER-2 have a positive correlation with the physical radiographical and mammodensity parameters.

Authors: Latif Amber , Iqbal Siddique Faiza
Published: January 2021

Background: Myofascial Pain Syndrome (MPS) is the most familiar painful musculoskeletal condition often caused by Myofascial Trigger Point (MTrP). The study objective was to determine the frequency of MTrP in the upper trapezius muscle and investigate its associating factors among physical therapists.
Methodology: A multi-center cross-sectional study was conducted over 258 male and female physical therapists between 20 to 45 years of age with at least 4 working hours/day. The participants filled a self-structured questionnaire, and bilateral upper trapezius MTrP was identified through the investigator's physical assessment. SPSS version 22.0 was used for statistical analysis. Frequencies and percentages were calculated for all categorical variables. Pearson chi-square test was used to compare the association of MTrP with age group, gender, and workplace. A p-value < 0.05 was considered significant.
Results:   Out of 258 samples, 70.5% (n=182) were found to have MTrP in the upper trapezius muscle. Within our group, the overall frequency of latent MTrP, i.e. 71.4%, was higher than active MTrP. Poor ergonomics of the workplace, lack of maintaining ideal posture, sleep deprivation, and emotional/psychological stress were the most rated associated factors.
Conclusion: Our study provides preliminary evidence suggesting a high-frequency rate of MTrP in the upper trapezius muscle. This study also suggested a few associated factors which are the cause of developing MTrP. These factors may be useful for developing guidelines for the risk factors and intervention of upper trapezius pain.

Published: January 2021

The major dilemma of marketing professionals is to justify the investment or expenditure on activities related to consumer engagement. Antecedents of consumer engagement are deeply rooted in the unique and specific differences that countries and/or regions present in terms of their social, legal, economic, political, and technological dimensions. Antecedents must be different for consumers from country a, region 1 than country b, region 2. There cannot be a commonality of antecedents for the 196 countries in the world. This research is among the first steps to make it possible. First, this research performed rigorous systematic literature review to consolidate all antecedents of consumer engagement acknowledged in previous quality research papers. Second, a systematic endeavour to generalize the antecedents of consumer engagement that fits all situation and context. The third contribution is the future research agenda of consumer engagement that is yet to be explored. For this purpose, strict inclusion and exclusion criteria implemented. Among hundreds of articles, a total 42 articles were selected, which fulfilled the criteria. Strict criteria were necessary to improve the quality of work. The study compiled all the antecedents in a table and concluded some highly ranked and high-frequency antecedents. A total of 22 antecedents were concluded among which, the study has discussed the topmost highly relevant yet most essential antecedents of consumer engagement. This study generalized the antecedents under broader terms. These top antecedents which are most essential are social, value, identity, interaction, involvement, experience, satisfaction, information, attachment, and participation. In the analysis part, all top antecedents discussed along with future research directions. Keywords: Consumer Engagement, Customer Engagement, Systematic Literature Review, SLR.

Published: January 2021

Stroke remains one of the most common diseases and causes of death. Reducing mortality from stroke is in great dependence on the effectiveness of its prevention, which, in turn, is impossible without an accurate understanding of its causes and mechanisms of development. The article represents the history of a patient with ischemic cardioembolic stroke that developed against noncompaction cardiomyopathy, a relatively rare disease that can be diagnosed with the use of available modern research methods. The algorithm for examining a patient with suspected cardioembolic stroke includes long-term Holter monitoring, echocardiography, CT and MRI of the heart, which makes it possible to identify rare causes of cardiac thromboembolism. Postexposure prophylaxis of stroke in such cases is likely to include the use of anticoagulants, but studies aimed to clarify most effective methods of recurrent strokes prevention in rare causes of cardiac thromboembolism are still being conducted.

Published: January 2021

The bowl feeder is a tool  feeder  for the process of separating the bowls one by one from the stack arranged vertically and then the bowl will cross the conveyor. Some industries have created screw and pneumatic methods  for feeding plastic bowl. However, the existing type of  bowl beside plastics there are also ceramics. Ceramic bowl are widely used for culinary. In this final project a bowl feeder device has been made where the process is by placing a dirty bowl in the container so that the bowl will pass one by one to 4 screws which are driven by a dc torque motor which functions for the separation process from the stack. Next, after the bowl reaches the conveyor, it will cross to get to the washing process which is driven by a dc torque motor. The feeder speed can be adjusted using pulse width modulation so it can have variations of speed in the feeder bowl process to get to the washing process. This feeder is able to feed 1411,7 bowl per hour using combination speed of 80 rpm screw motor and 135 rpm conveyor motor.

PLTU Pacitan adalah salah satu pembangkit listrik di Jawa Timur yang memiliki kapasitas 2 x 315 MW yang dibangun pemerintah pada Fast Track Program 1. Instrument Air Compressor (IAC) adalah salah satu peralatan bantu di PLTU Pacitan yang berfungsi sebagai suplai udara ke sistem pneumatik seluruh plant. Namun, peralatan ini tidak bisa dimonitor oleh operator Central Control Room (CCR) dengan maksimal. Parameter yang dapat dikontrol sangat terbatas. Hal ini dikarenakan terbatasnya jumlah terminal Field Bus Module (FBM) yang tersedia. Rumusan masalah adalah bagaimana cara membuat modul komunikasi untuk menampilkan parameter Instrument Air Compressor System ke display HMI operator CCR secara real time. Tujuan dari perancangan alat ini adalah membuat modul komunikasi yang aman dan handal untuk menampilkan semua parameter Instrument Air Compressor yang ada dilokal tampil di display komputer CCR. Metode yang digunakan adalah pengontrolan dan pemantauan parameter ditransmisikan dari lapangan ke CCR menggunakan komunikasi serial protokol modbus RS485. Untuk meningkatkan pengelolaaan peralatan tidak hanya dikontrol dan dimonitor tetapi juga menampilkan fault alarm untuk mengingatkan operator bahwa peralatan mengalami ketidaknormalan. Perancangan prototype mengunakan komputer sebagai HMI dan arduino nano sebagai mikrokontroller. Manfaat dari perancangan modul komunikasi ini adalah mengganti peran FBM yang jumlah terminal input dan output yang terbatas dan memiliki harga yang mahal serta meningkatkan kehandalan Instrument Air Compressor System.

Banyaknya orang tua yang memandang sebelah mata tentang kelas masyarakat yang ada di sebuah sekolah. Ini hanya sebatas mereka tahu bahwa masyarakat hanyalah alat penghimpun dana dan tidak berpengaruh bagi pendidikan anak. Nyatanya banyak di sekolah yang mempunyai struktur kemasyarakatan tetapi hanya untuk formalitas saja. Mereka akan pindah saat ada kunjungan. Oleh karena itu penulis mengangkat judul ini untuk mengetahui bagaimana sebenarnya peran masyarakat. Hasil penelitian dapat disimpulkan menjadi tiga hal, yaitu: (1) asosiasi kelas berperan sangat penting dalam prestasi belajar siswa. Peran masyarakat tersebut antara lain: kegiatan tahunan setahun dua kali, kegiatan sehari-hari dalam memantau pembelajaran di sekolah, kegiatan kelompok kelas dalam mengikuti kegiatan di sekolah dan kegiatan sosial. (2) Faktor pendukung terbentuknya perkumpulan kelas meliputi keterbukaan guru dalam menghadapi keluhan wali tentang pembelajaran anak, adanya motivasi dari komite sekolah, besarnya keinginan wali sendiri dan menghindari kesalahpahaman antara guru dan orang tua. (3) Bagaimana mengatasi faktor penghambat pergaulan dengan kegigihan guru dan ketua masyarakat memberikan motivasi dan dorongan akan pentingnya peran orang tua dalam meningkatkan prestasi belajar siswa.The number of parents looking one eye about the class of society that exist in a school. This is only to the extent that they know that the community is only a means of collecting funds and there is no effect for children’s education. In fact many in schools that have the structure of the community but just for formality only. They will move when there is a visit. Therefore the author raised this title to know how the role of the actual community. The results can be concluded into three things, they are: (1)class associations play so important role in student achievement. The role of the community they are: annual activities a year twice, daily activities in monitoring learning in schools, class group activities in following activities at school and social activities. (2) Factor supporting the formation of class associations include teacher opennes in the face of the guardian’s complaints about child’s learning, there is motivation from school committe, the magnitude of the wishes of the guardians themselves and avoiding misunderstandings between teachers and parent. (3) How to overcome the factors inhibiting the association with the persistence of teachers and chairperson of the commounity provide motivation and encouragement of the importance of the role of parents in improving student achievement

Представлены результаты прямого сравнения детального кинетического моделирования процесса сажеобразования при пиролизе и окислении различных углеводородов численными методами моментов, секционным методом и дискретным методом Галеркина с результатами экспериментальных измерений в отраженных ударных волнах. Получено удовлетворительное совпадение результатов кинетических расчетов методом моментов и дискретным методом Галеркина по выходу сажи, среднему размеру частиц и полной концентрации частиц с результатами экспериментов. Впервые в расчетах по предложенному авторами единому кинетическому механизму сажеобразования получены детальные функции распределения частиц по размерам для всех исследованных в работе углеводородов. Полученные функции распределения имеют бимодальный вид. Мода мелких частиц характеризует образование зародышей и начало роста частиц сажи, а мода крупных частиц - поверхностный рост и коагуляцию частиц сажи.

Показана возможность применения триангулярной диаграммы пределов воспламенения горючих газов для наглядного сравнения режимов диффузионного горения при различной степени балластирования окислителя и самого горючего газа инертными компонентами. Для принятого допущения о том, что температура в зоне реакции диффузионного пламени, наряду с температурой послепламенной зоны, оказывает влияние на образование оксидов азота и что снижение температуры в зоне реакции диффузионного пламени при прочих равных условиях должно снижать концентрацию оксидов азота, показана перспективность технологии сжигания с балластированием воздуха (или горючего газа) инертными компонентами по сравнению с технологией ступенчатого сжигания газа в чистом воздухе. Приведен пример конструкции горелки для сжигания газа в воздухе, сильно забалластированном дымовыми газами рециркуляции. Представлены экспериментальные результаты по образованию оксидов азота на таких режимах на промышленном котле.

Синтезирована 1,1'-ферроцендикарбоновая кислота (ФДК), а также ее нерастворимые в воде соли - медная, железная и свинцовая, и исследовано их влияние на скорость горения среднекалорийного топлива Н. Показано, что наибольшей эффективностью в индивидуальном виде обладает медная соль ФДК(МФДК), 3% которой в интервале давлений 1-10 МПа увеличивают скорость горенияв ~ 2,2-1,9 раза. Углеродные нанотрубки (УНТ) значительно увеличивают эффективность действия МФДК^1 = 4,5; Z10 = 3,1). Найдено оптимальное соотношение между катализатором и УНТ, при котором его влияние проявляется в широком диапазоне давлений (до 60 МПа). Железная соль (ЖФДК) слабо влияет на скорость горения топлива при давлении до 2 МПа, а при более высоком давлении - только в сочетании с УНТ. Обнаружено интересное явление - ЖФДК снижает эффективность действия МФДК. Предложено объяснение этому факту.

Продемонстрирована возможность создания на основе термоэлектрических модулей импульсных генераторов электричества закрытого типа, в которых химическая энергия при горении порошков металла на воздухе преобразуется в электричество. В отличие от генераторов открытого типа с протоком горячей среды в рассмотренном случае практически вся химическая энергия горения топлива в виде теплового потока может быть пропущена через термоэлектрические модули. Показана возможность организовать диффузионное горение порошка металла в ограниченном объеме сборки генератора в режиме принудительной конвекции окислителя. Предварительные эксперименты продемонстрировали успешную работу термоэлектрического генератора (ТЭГа) мощностью ~ 4 Вт в течении 20 мин при токе в нагрузке ~ 1 А. Рассмотрен импульсно-периодический режим работы генератора при периодическом нагреве и охлаждении модуля, который позволяет увеличить средний коэффициент полезного действия (КПД) преобразования тепловой энергии в электрическую, по крайней мере, в 1,6 раз.
LA IMPORTANCIA DE LA MUSEOGRAFÍA EN LA DIFUSIÓN DE LA CIENCIA EN EL MUSEO ARQUEOLÓGICO NACIONAL: EL EJEMPLO DE LA VITRINA CERO DEDICADA AL PATRIMONIO CERÁMICO DE LAS COGOTAS (CARDEÑOSA, ÁVILA)

La “Vitrina Cero” del Museo Arqueológico Nacional se enmarca en el ámbito de las iniciativas expositivas que las instituciones museísticas desarrollan en la actualidad y que persiguen tanto fomentar la investigación de sus colecciones, como completar el discurso museográfico de su exposición permanente. La titulada “De 0 a 140 revoluciones por minuto: la introducción del torno en la Península Ibérica” sirve como ejemplo para presentar el origen, objetivos e historia de esta iniciativa concreta, así como para repasar la evolución museológica y museográfica que desemboca en la práctica actual. Además, a través de ella, se reflexiona sobre la importancia de la investigación en los museos y se detalla el proceso de creación de la misma.
CHAÎNE OPÉRATOIRE, TECHNOLOGICAL NETWORKS AND SOCIOLOGICAL INTERPRETATIONS
Authors: Roux Valentine
Published: January 2021

In this paper, I first argue that technological analysis of archaeological assemblages in terms of chaînes opératoires is a privileged qualitative approach to reconstruct technological networks, namely networks of socially linked object-makers. This is a first step before explaining dynamic phenomena such as diffusion of techniques or emergence of shared norms at the population level. The second step is to call upon sociological regularities since archaeology alone cannot provide a fine-grained temporal resolution to evaluate how micro-level interactions might have scaled up in changes. In the second part of the paper, I give archaeological examples and illustrate how to use sociological regularities for explaining past dynamics.

Entrevista a Alejandro Villalobos Pérez.En muy pocas ocasiones una presentación llega a ser tan determinante como la que hizo Rafael López Guzmán, conmigo y Alejandro Villalobos. Hace ya veinte años, ambos visitaban la ciudad califal de Medina Azahara con motivo de la exposición El esplendor de los Omeyas Cordobeses, y el primero advirtió al segundo de que a un joven, por entonces, profesor del departamento de Historia del Arte de la Universidad de Granada, se le había asignado la materia de Arte Prehispánico. El encargo era claro con la amistad que ambos tienen, formarme con el profesor Villalobos en arquitectura y urbanismo prehispánicos desde una visión integradora en la que arqueología y antropología iban de la mano…
