Bioaccumulation of cadmium was assessed in different tissues of the benthic fish Solea senegalensis. Juvenile Senegalese soles were simultaneously exposed to cadmium-contaminated diet (Hediste diversicolor) and water during 14 days and allowed to depurate for another 14 days. Cadmium content was measured in muscle, gills, liver and intestine, with recorded values increasing in these tissues in this same order. Muscle showed a considerably lower cadmium accumulation after 14 days of uptake. Cadmium kinetics in juvenile Senegalese soles revealed that the highest uptake flux of this metal occurred in the intestine. Cadmium depuration from the liver was not detected, which suggests the existence of a storage compartment for this metal in Solea senegalensis during uptake and depuration. Comparisons between maximum acceptable values for cadmium in the muscle, the Target Hazard Quotient and the Estimated Weekly Intake, indicated that acceptable limits were not exceeded, and the muscle of juvenile Senegalese soles could be considered safe for human consumption.
Die Frauenweihe zwischen der
ursprünglichen und der geweihten Sakramentalität
Authors: Petrov Emanuel
Published: February 2021

Die katholische Kirche steht sowohl in
der natürlichen Reihenfolge der Schöpfung als auch in der übernatürlichen
Reihenfolge der Erlösung für die Gleichwürdigung der Geschlechter. Diese zwei
Reihen entsprechen zwei Sakramentalitäten: die ursprüngliche und die geweihte priesterliche
Sakramentalität. Beide Sakramentalitäten beinhalten eine selbstlose Hingabe und
eine gehorsame Sendung, Gott zu repräsentieren, seine Ehre
zu bezeugen und damit die Teilhabe am göttlichen Leben zu beerben und
tatsächlich zu leben. Beide sind die Grade des gleichen Planes Gottes mit dem
Menschen. Trotzdem kann die geweihte Sakramentalität nur der getaufte Mann
empfangen. Johannes Paul II. behauptet, dass die Kirche aufgrund ihrer
göttlichen Verfassung keine Vollmacht habe, Frauen die Priesterweihe zu
spenden. Anderseits gibt es zahlreiche Möglichkeiten und Dienste, damit die
Frauen der Herrlichkeit Gottes dienen und die Verherrlichung des Menschen
verwirklichen. Dementsprechend ist die Mutterschaft in der Hauskirche oder der
Jungfrauenstand,
eine Art Priestertum an sich.
Coupled Anti Fuzzy Subrings Using t-Conorms
Authors: Ampadu Clement Boateng
Published: February 2021

The aim of this paper is to introduce the concept of coupled anti fuzzy subrings by using t-conorm C. By using t-conorm C; we consider the relationship between coupled subrings and coupled anti fuzzy subrings and we prove that the intersection of two coupled anti fuzzy subrings are also coupled anti fuzzy subring. Also we obtain some results for coupled anti fuzzy subrings under the ring homomorphisms. Finally, we show that the quotient of coupled anti fuzzy subring is also a coupled anti fuzzy subring with respect to t-conorm C. Our work is inspired by [1].
The Impact of Coach Leadership Style on Resilience of Volleyball Players
Authors: Patsiaouras Asterios
Published: February 2021

The purpose of this study was to investigate the impact of coach leadership style on resilience level of volleyball players and to trace possible differences that exist between the two genders. Participants included 101 volleyball players (53 females and 48 males) and 31 coaches (11 females and 20 males), with the Self Evaluation Resilience test and the Leadership Scale for Sport (LSS) used as instruments. The data was analyzed with SPSS 21.0 using t-test for independent samples, and simple regression (stepwise) analysis. Results of t-test showed statistically significant differences between male and female volleyball players in ‘‘orientation on solution and aims’’ and ‘‘self-efficacy’’ variables, with no other statistically significant differences observed for the rest resilience variables. Additionally, no statistically significant differences were observed for the LSS variables between the two genders of volleyball coaches. The results of simple regression (stepwise) analysis suggest that the autocratic behavior of volleyball coach has a significant impact on volleyball players’ resilience. Future research should investigate whether variables such as anxiety affect the resilience level of volleyball players.
Choral Works by Rodion Shchedrin. 21 Century
Authors: Кривицкая Евгения Давидовна
Published: February 2021

Статья представляет собой обзор сочинений для хора a cappeLLa, созданных Родионом Щедриным в XXI веке. Произведения рассматриваются в хронологическом порядке, многие из них вдохновлены творческими контактами с Камерным хором Московской консерватории и с его руководителями - основателем коллектива Борисом Тевлиным и его преемником Александром Соловьёвым. Среди хоровых сочинений композитора есть и произведения на стихи российских поэтов - Андрея Вознесенского, Владимира Маяковского, Велимира Хлебникова, и опусы, написанные на библейские тексты, - «Эпиграф графа Толстого к роману “Анна Каренина”», «Месса поминовения»; последние можно отнести к области духовной музыки. Ряд сочинений отмечен гражданским пафосом (Диптих, «Два последних хора»). В партитурах 2020 года, созданных в период пандемии, в самоизоляции, автор размышляет о смысле бытия (Триптих). Щедрин постоянно экспериментирует с жанрами хоровой музыки. Ярким примером его изобретательности в творчестве последних лет являются Русские народные пословицы. В более ранней Серенаде (2003) традиционный жанр трактован новаторски: текст произведения целиком основан на междометиях.

The article is a review of compositions for a cappella choir, written by Rodion Shchedrin in the 21 century. The works are viewed in chronological order, many of them are inspired by creative reLationships with the Chamber Choir of Moscow Conservatory and with its Leaders-the founder of the collective Boris TevLin and his successor Aleksandr Solovyov. Among the composer's choral works, there are music on verses by Russian poets-Andrei Voznesensky, Vladimir Mayakovsky, VeLimir Khlebnikov, and opuses written on bibLicaL texts-“Count ToLstoy's Epigraph to the NoveL ‘Anna Karenina'”, Mass of Commemoration; the Latters can be attributed to the fieLd of sacred music. A number of works are marked by civic pathos (Diptych, “The Last Two Choirs”). In the 2020 scores, created during the pandemic, in self-isolation, the author reflects on the meaning of being (Triptych). Shchedrin constantLy experiments with genres of choraL music. A striking exampLe of his ingenuity in the current oeuvre is the “Russian FoLk Proverbs”. In the earLier Serenade (2003), the traditionaL genre is interpreted in an innovative way: the text of the work is entireLy based on interjections.
From the Archive of Valeria Tsenova

Published: February 2021

Публикация архивных материалов, подготовленная и прокомментированная Т. С. Кюрегян, посвящена юбилею В. С. Ценовой (1960-2007) - выдающегося отечественного музыковеда, специалиста в области современной композиции, знатока творчества Э. В. Денисова. Со студенческих лет создавая научную базу для монографии о композиторе (написанной позже вместе со своим научным руководителем Ю. Н. Холоповым), Ценова общалась с самим Денисовым (у которого в консерватории училась в классе инструментовки и чтения партитур), с его матерью, А. И. Титовой, при ее поддержке установила связь с профессором З. И. Клементьевым, обучавшим Денисова математическим дисциплинам в Томском университете. Воспоминания Клементьева, датированные осенью 1984 года, как и три письма Денисова из Карелии лета того же года публикуются в полном виде впервые.

The publication of archival materials prepared and commented by T. S. Kyuregyan is dedicated to the anniversary of V. S. Tsenova (1960-2007), an outstanding Russian musicologist, a specialist in modern composition, and a connoisseur of E. V. Denisov's work. From her student years when developing a scientific base for a monograph about the composer (written later together with her supervisor Yu. N. Kholopov), the young Tsenova communicated with Denisov (she studied in the Conservatory at his class of instrumentation and reading scores), with his mother A. I. Titova; with her support she established relations with Professor Z. I. Klementiev, who taught Denisov mathematical disciplines at Tomsk University. Klementiev's memoirs of the autumn of 1984, as well as Denisov's three letters from Karelia written in the summer of the same year are published in the full version for the first time.
Biliary system functional condition in patients with chronic cholecystitis against the background of diabetes mellitus type 2
Authors: Zhuravlyova L.V. , Tymoshenko G.Yu.
Published: February 2021

Overlay of diseases of the biliary system to diabetes mellitus type 2 can contribute to the enhancement of disorders of protein, lipid and carbohydrate metabolism and affect the mechanisms of regulation at the cellular molecular level. Therefore, the need for early diagnosis and study of the features of the course of chronic cholecystitis against the background of diabetes mellitus type 2 is a pressing issue of internal medicine. The motor-evacuation and cholecretory functions of the biliary system and the features of the course of chronic cholecystitis on the background of diabetes mellitus type 2 were studied. 93 patients were examined, of which 62 were patients with combined diabetes mellitus type 2 and chronic cholecystitis and 31 patients with isolated chronic cholecystitis. The control group was represented by 20 apparantly healthy individuals, who were representative of the age and number of male and female probands. The course of chronic cholecystitis was found to be accompanied by impaired gallbladder motor (evacuation) function, which was manifested by an increase in the latency period, the volume of the cavity of the gallbladder, the emptying coefficients in the dynamics and a decrease in the index of contraction of the gallbladder. In the presence of diabetes mellitus type 2, an atypical course of chronic cholecystitis may be formed, characterized by motor-evacuation disorders of the biliary tract and physico-chemical changes in bile, the severity of which exceeds those of isolated chronic cholecystitis. The peculiarities of the course of chronic cholecystitis in patients with diabetes mellitus type 2 are manifested by insignificant clinical symptoms and distinct changes at both stages of cholecystosonography, which may be the result of the development of autonomic neuropathy. In diabetes mellitus type 2, it is advisable to determine the status of the gallbladder (cholecystosonography) in order to prevent the risk of complications (cholelithiasis) and timely administration of antimicrobial therapy in the presence of an additional inflammation.

Authors: Pulyaeva I.S.
Published: February 2021

The results of examination and treatment by carotid endarterectomy method in 23 patients with atrial fibrillation and lesions of the carotid arteries in the State Institution «V.T. Zaitsev IGES NAMSU» from 2017 to 2019. Antiplatelet agents (aspirin were prescribed in 20 patients, clopidogrel were prescribed in 3 patients) were prescribed due to the presence of cardiovascular disease and previous myocardial infarction. No patient was found to have impaired cerebral circulation in the postoperative period. Tension hematoma was diagnosed in two patients and bleeding from soft tissues, which required revision of the postoperative wound with hemostasis, in one. It has been shown that patients with hemodynamically significant stenosis and unstable plaque of the carotid arteries most often develop atherothrombotic stroke. Patients with stenosis of the carotid arteries and rhythm disturbances should receive antiplatelet and anticoagulant therapy with blood pressure correction in the absence of bleeding.

Authors: KOÇAK Emre , ÖRKCÜ H. Hasan
Published: February 2021

According to the efficiency scores obtained by Data Envelopment Analysis (DEA), the main problem for inefficient decision-making units (DMU) is the factors that cause inefficiency. To deal with this problem, various studies have been handled, such as decomposing the total efficiency score, and two-stage DEA which can divide the whole process into two parts has been developed. In this study, independent models where the whole process is called a black box and related models where the series relationship is established in the whole process are discussed comparatively. These models are used to measure graduate education performances and scientific and technological research competency performances of state universities in Turkey. When the overall performances of universities are examined; Gebze Technical, Hacettepe, İstanbul Technical, İzmir Institute of Technology and Middle East Technical have been determined as efficient universities both in terms of overall performances of universities and in terms of independent model and related model. İstanbul, Ankara, Boğaziçi and Gazi, have beendetermined as efficient universities only in terms of independent model. Furthermore, this study is consistent with the research universities determined by the Council of Higher Education through certain criteria.

Authors: Begines Ruiz Belén , Alcudia Cruz Ana , Moreno Rodríguez Nazaret , Galbis Fuster Elsa , Benito Hernández Elena María
Published: February 2021

En esta práctica se repasarán distintas formas de expresar la concentración de una disolución. Así mismo, se procederá a la preparación de volúmenes predeterminados de dos disoluciones con dos concentraciones en molaridad dadas, a partir de dos productos de partida en distintos estados: un sólido (NaCl) y una disolución acuosa de un gas (NH3).

En esta práctica se detalla el procedimiento práctico a llevar a cabo para preparar una disolución de un determinado soluto a una concentración estipulada. Para ello, primero es necesario calcular la cantidad de soluto que habría que usar, teniendo en cuenta el volumen deseado de la disolución y la concentración fijada. Una vez tomada la cantidad requerida de soluto (ya sea sólido o líquido), este se añade al matraz aforado adecuado (según el volumen de disolución que se quiere preparar) y se añade disolvente hasta la señal de enrase del matraz. Una vez hecho esto, sólo habría que agitar la muestra para disolver o distribuir el soluto uniformemente.
Prácticas de fundamento de ciencias de la materia: cinética química. Estudio cualitativo.
Authors: Begines Ruiz Belén , Alcudia Cruz Ana , Moreno Rodríguez Nazaret , Galbis Fuster Elsa , Benito Hernández Elena María
Published: February 2021

En esta práctica se determinará de manera cuantitativa la velocidad de la reacción entre el Zn y el HCl, a partir del tiempo necesario para que se consuma una cantidad inicial de Zn determinada. A continuación, se observarán, de forma cualitativa, cómo determinados factores influyen en la velocidad de una reacción, aumentándola o disminuyéndola, según el caso. Estos factores serán la concentración, la temperatura y la superficie de contacto.

La Cinética Química es la rama de la Química que estudia la velocidad con la que ocurren las reacciones. Esta velocidad se define como la variación de la concentración de una de las especies que intervienen en la reacción dividida entre el tiempo transcurrido en esa variación. En esta práctica, se procede al cálculo de la velocidad de una reacción estipulada. Para ello, inicialmente se hará un estudio para determinar qué especie se debe considerar para seguir la evolución de su concentración. Una vez hecho esto, se medirá el tiempo que esta especie tarda en pasar de una concentración inicial determinada hasta una concentración final, también dada. Con estos datos, se podrá calcular la velocidad de dicha reacción. Asimismo, se procederá a investigar cualitativamente cómo variación de la concentración de las especies, la temperatura o la superficie de contacto pueden modificar la velocidad de una reacción.

Published: February 2021

En esta práctica se llevará a cabo una decantación, que es un método físico de separación de los componentes de una mezcla heterogénea formada por un líquido y un sólido, o por dos líquidos inmiscibles. Más concretamente, se realizará la separación de una mezcla formada por diclorometano y una disolución acuosa de I2, estudiando primero cuál de los dos líquidos es más denso. Así mismo, se observará el proceso de extracción del I2, el cual migra desde el agua al diclorometano.

En esta práctica se muestran dos procesos físicos. En primer lugar, se explica el concepto de decantación, que es un método físico de separación de los componentes de una mezcla heterogénea formada por un líquido y un sólido, o por dos líquidos inmiscibles. Así mismo, se observa el fenómeno de extracción, proceso por el cual, un soluto disuelto en un disolvente migra a otro disolvente inmiscible con el primero y por el que el soluto tiene más afinidad, es decir, es más soluble. Por último, se presenta un proceso químico por el cual, una sustancia química (I2) se transforma en otra (I-) por reacción con una sal (tiosulfato de sodio). Esta transformación se observa por el cambio de color en la disolución, que pasa de rosa (cuando el yodo está en forma de I2) a incolora (cuando el yodo está en forma de I-).
The Tides are Turning: Reconciling the Hidden Pearling History of Broome
Authors: Appleby Naomi , Pigram Lloyd , Skyring Fiona , Yu Sarah
Published: February 2021

In 2015 Yawuru people began the slow and emotional journey to repatriate their ‘Old People’ whose skeletal remains had been taken from their Country by collectors working mostly for museums. One group of ancestors were young pearlshell divers who had been sold to the Dresden Museum in Saxony, Germany, in 1895 by pearlers. Their bodily traumas revealed the brutal treatment they endured before their untimely deaths. The journey brought the Yawuru and Karajarri elders and the curators of the Ethnographic Museums of Saxony together in their quest to find out what had happened to these people and to rehumanise our ancestors who had, for so long, been treated as objects in the museum collections. This article presents our reflections on the journey back to Germany to retrieve the ancestors, the development of our ‘Wanggajarli Burugun’ (‘We are coming home’) project and the findings from our research into the slavery of the early pearling days in and around Broome, Western Australia. It also reveals the emotional journey of our community as they delved into the trauma of this formerly unknown colonial practice of ‘bone-collecting’, and how, through the spirit of mabu liyan and a process of culturally informed engagement process we were able to address the dark deeds of the past to lead the journey to healing and reconciliation.
From ‘Plant Hunter’ to ‘Tomb Raider’: The Changing Image of Amalie Dietrich
Authors: Affeldt Stefanie , Hund Wulf D.
Published: February 2021

In the context of her bicentenary in 2021, Amalie Dietrich will again be celebrated as a feminist paragon or condemned as a racist culprit. Her stay in Australia will be central to these contrasting approaches to her biography. There, she gathered a remarkable amount of native plants, animals, ethnological everyday objects – and human remains. In this context, she was subjected to suspicions of incitement in murder early on and to allegedly critical investigations concerning her role in the anthropological desecration of corpses in recent times. In this paper, we contribute some arguments to the clarification of this controversial subject. It focuses on the treatment of image of Amalie Dietrich in the German discourse from the Kaiserreich via the Weimar Republic, the fascist ‘Reich’, the Federal Republic as well as the Democratic Republic to reunited Germany. As a result, we argue that a critical biography of Amalie Dietrich must integrate the appreciation of her contribution to botany and zoology with a critique of her role in the racist history of anthropological grave robbery and desecration of human remains.
Australian Bushfires: Current trends, causes, and social-ecological impacts
Authors: Bott Lisa-Michéle , Fastenrath Sebastian
Published: February 2021

Bushfires are common events in Australia reaching their peak each summer season. However, the last bushfire season from July 2019 until March 2020 was unprecedented. An estimated area between 240,000 up to 400,000 km² burned, with the southeast coast being particularly affected. The images of burnt flora and fauna and the fires that raged for months went around the world. It became clear how vulnerable both Australia’s communities and ecosystems are to this natural hazard, which is becoming more frequent and intense. Australia’s southeast is increasingly vulnerable against the often sudden event of bushfires. This article discusses the current trends, causes for this extreme fire season, the socio-economic and ecological impacts, and the resulting adaptation processes.

Published: February 2021

El artículo trata sobre el régimen especial de protección jurídica de los conocimientos colectivos de los pueblos indígenas asociados con la biodiversidad, que ha sido instaurado en el Perú con la Ley 27811. El objetivo principal de la investigación ha sido evaluar si dicho régimen de protección es beneficioso en forma efectiva para los pueblos indígenas, así como proponer medidas y acciones tendientes a que se logren los objetivos por los cuales la mencionada Ley fue dada.Se aplica un método exegético-dogmático para el análisis de sus disposiciones, se las contrasta con la realidad y se busca con propuestas su eficiencia social. Los resultados revelaron que deben hacerse modificaciones legales, para que no haya un porcentaje de regalías a pagar tan alto por las empresas que pudieran estar interesadas en explotar económicamente los conocimientos colectivos. Además, se dan una serie de propuestas según las cuales el Estado debe impulsar activamente la relación entre pueblos indígenas y las universidades, centros de investigación y empresas privadas que pudieran servirse de estos conocimientos, especialmente de aquellas vinculadas con el sector farmacéutico, cosmético o de productos naturales. Además, se concluye que deben explorarse diseños institucionales y legales alternativos o complementarios, en los que el Estado profundice en la bioinformática y bioprospección, a partir de los conocimientos colectivos de los pueblos indígenas.
Jezuicka filozofia państwa w Polsce, 1564–1668

Published: February 2021

Jezuici stanowili zawsze przedmiot licznych publikacji, ale szczególnie w ostatnim okresie literatura na ich temat wzbogaciła się o wiele cennych rozpraw naukowych. W ich świetle jawi się nowy obraz zakonu o różnorodnych odcieniach i barwach, zastępując dotychczasowy białoczarny. Dyskusjom nie ma jednak końca. „Sukcesom zakonu - pisał Janusz Tazbir - odpowiadały rosnące stosy literatury antyjezuickiej, która również w Polsce przetrwała (na przelomie XV I i XVII wieku) szczytowy okres swego rozwoju. Spór o rolę zakonu w politycznych, kulturalnych, a nawet gospodarczych dziejach Europy trwa już od przeszło czterystu lat i nic nie zapowiada jego rychłego zakończenia. Przy ocenie jezuióöw w zbyt małym chyba jednak stopniu zwracano uwagę na fakt, iż byli oni pionierami „wielkiego kompromisu'' we wszystkich niemal dziedzinach, z wyjątkiem oczywiście kompromisu
z „herezją". I dzięki temu też, czysto wbrew wlasnym intencjom, stawali się prekursorami nowych rozwiązań".
Toward the megapixel live electrooptic imaging technique
Authors: Tsuchiya Masahiro , Sato Taku , Komuro Atsushi
Published: February 2021

High-resolution electrooptic images have been successfully acquired, whose pixel number of 0.2 M is a record-high for the non-scanning acquisition of high-frequency electric field distributions and is a triple of the conventional record. The image acquisition was conducted using a megapixel image sensor, where the reduction in the pixel number from 1 to 0.2 M is due to unessential vignetting and can be prevented in future. The result suggests possible realization of the live electrooptic imaging technique in the megapixel range with presently available hardware employed, which had been considered unlikely.

Cement production became responsible of polluting the atmosphere by the emission of greenhouse gases. This issue motivate the researchers to work hard to develop a new cementitious materials used in concrete having much lower foot print in environmental pollution. This paper presents the development of high strength geoploymer concrete using nano silica. Ground granulated blast furnace slag (GGBFS) is used as main cementitious material and silica fume (SF) is used as cement replacement by different ratios. The alkaline activator is used in different temperature and samples cured by different methods. Nano silica then added to the optimum geopolymer concrete sample by ratios 1, 2 and 3% of the total weight of cementitious materials. Samples tested for mechanical properties. The results showed that using hot activator and oven curing samples gives higher mechanical properties. Also using nano silica up to 2% increases the compressive strength up to 24% at age 28 days.

Published: February 2021

The paper devotes to modeling tasks of multidimensional inertialess objects with delay (MIOD). The description of identification scheme of MIOD is determined. The proposed identification scheme includes not only blocks of a process and a model but also a data preprocessing block to improve modelling accuracy. A new method of data preprocessing which includes outliers detection and sparsity filling is proposed. It allows generating new training samples based on initial data that is obtained by measurement of input and output variables of the process. A software package is developed to conduct computer experiments. The results of the study show that the proposed algorithms are universal and can be applied to simulate various objects that are described with liner, nonlinear algebraic and nonlinear transcendental mathematical equations. Computational experiments have shown satisfactory accuracy of the algorithms. Proposed algorithms can be used in modeling and control tasks for inertialess objects in various areas of industry such as metallurgy, petrochemicals and etc.

Advances in technology encourage Small and Medium Enterprises (UKM) owners to develop their businesses by making online purchases, one of which is Pak Dede's Soto Mie inn. An attractive packaging design can encourage positive perceptions from customers when making online purchases. Therefore, the aim of this research is to design Pak Dede's Soto Mie packaging that involves feelings, emotions, or consumer orientation using the Kansei engineering method. The first stage of the Kansei engineering method in this study is the collection of Kansei words by distributing questionnaires to Pak Dede's Soto Mie customers. The second stage is grouping the Kansei words using the Principal Component Analysis (PCA). The third stage is the formulation of Pak Dede's Soto Mie packaging design concept that will be designed using the Association Rule Mining (ARM). The fourth stage is designing an alternative packaging design for Pak Dede's Soto Mie. Then the last stage is the selection of design alternatives. Based on the results of the Association Rule Mining (ARM), there are two design concepts that are considered, namely simple and eco-friendly. In the selection of design alternatives, the eco-friendly design on the packaging of Pak Dede's Soto Mie is preferred by customers.

With a predicted 50 billion devices by the end of 2020, the Internet of things has grown exponentially in the last few years. This growth has seen an increasing demand for mobility support in low power and lossy sensor networks, a type of network characterized by several limitations in terms of their resources including CPU, memory and batter, causing manufactures to push products out to the market faster, without the necessary security features. IoT networks rely on the Routing Protocol for Low Power and Lossy Network (RPL) for communication, designed by the Internet Engineering Task Force (IETF). This protocol has been proven to be efficient in relation to the handling of routing in such constrained networks, However, research studies revealed that RPL was inherently designed for static networks, indicating poor handling of mobile or dynamic topologies which is worsen when introducing mobile attacker. In this paper, two IoT routing attacks are evaluated under a mobile attacker with the aim of providing a critical evaluation of the impact the attacks have on the network in comparison to the case with static attacker. The first attack is the Rank attack in which the attacker announces false routing information to its neighbour attracting them to forward their data via the attacker. The second attack is the DIS attack in which the attacker floods the network with DIS messages triggering them to reset their transmission timers and sending messages more frequently. The comparison were conducted in terms of average power consumption and also the packet delivery ratio (PDR). Based on the results collected from the simulations, it was established that when an attacking node is mobile, there’s an average increase of 36.6 in power consumption and a decrease of 14 for packet delivery ratios when compared to a static attacking node.

Once Scrum process model is adopted by an enterprise, changes in the organization are common. New practices and processes are needed by the enterprise to start removing dysfunctions and problems that are identified with Scrum adoption. These variations are isolated when Scrum is applied on a single project. Some new practices, processes and techniques help to adopt Scrum at an enterprise level and are not new. They are objectively different in the way they work in current situation. In this research work engineering practices that helps in developing the projects of enterprise are illustrated. The study also focuses on how the new practices are different while using Scrum is also discussed.

The pump requirement is required to meet the specified performance parameters means the required pressure (head) and flow, using less power. For water pump applications, periodic maintenance is required to check worn parts such as wear ring, shaft sleeves. In such a case the direct separation case pumps are reliable. If a given work point can meet the range of pumps of the available separate cases, it is necessary to develop a new pump and the upgraded pump should be more efficient with the considered power problems. With the help of computational fluid dynamics, the complex internal flow of the pump in the case of equilibrium separation can be accurately predicted, thus facilitating the construction of the pump. Simulation provides the most complete performance testing and important diagnostic details that help the engineer quickly and increase composition. As a result, the company is able to quickly create new designs such as a fully patented water pump with a patent. Pressure suction can be problematic during operation and operation of centrifugal pumps. Such pressure stimulants are traditionally investigated but quantitative analysis techniques allow these effects to be tested. Numerical analysis is done with a multi-reference framework to predict the flow field within the entire pipeline and impeller.

Indonesian State Police (Korlantas POLRI) recorded the number of accidents in 2018 as many as 109,215 accidents. The number has incresed 4.69 percent compared to 2017 as many as 104,327 events. Road traffic accidents are caused by human error, the driver in this case. The driver's mistake is influenced by several factors, one of them is they cannot expect the road condition when they drive a vehicle at high speed. To solve this problem, drivers need information that can show road conditions. So, we present a new approach for detecting damaged roads by applying augmented reality technology. This research produces a road condition information system to help drivers get information about road conditions via smartphone. This system uses augmented reality technology with a markerless GPS Based Tracking method. The development of this system requires several stages such as collecting the data, data conversion, data classification, and views road condition. The researchers gathered the road condition data from the Public Work Department Semarang. This department itself undertakes a task to control the road condition in Semarang The trial of this system includes all drivers in Semarang city. Based on the results of the questionnaire responded to by 93 respondents, this test obtained an average value of 68%. So this system gets a pretty good response from the driver. Through this system, all drivers can avoid the damaged road condition which can cause traffic-congested and accident.

Information extraction is systematic process of extracting structured information from documents which has both unstructured and semi structured data set. Data available over the web is unstructured which is processed and delivered that may be challenging due to massive data over web. Bigdata analytics approach is used in the computation field where massive data is managed and processed as information. Data from various sources like industries, institutes are processed using algorithms in efficient means employing web of things or Internet of things used to mine such a large data. Bio inspired algorithms have evolved from application of heuristic approaches to meta-heuristic and hyper-heuristic methodologies. Bio inspired techniques are categorized into human inspired algorithms, Swarm Intelligence algorithms, evolutionary algorithms and ecology based algorithms. Genetic algorithms are purely heuristic in nature and are employed for computation and extracting information and from big data. This improves the computation speed effectively for extracting web related information as evolutionary algorithm resolves information extraction problems. The Ant colony and Particle Swarm Intelligence algorithms are of meta-heuristic in nature. The Cuckoo search, Artificial Bee Colony, Firefly algorithm and Bat algorithms are of hyper heuristic in nature i.e., they employ a combination of methods. Web information extraction using bio inspired concepts and genetic operators increases efficiency, capability to search particular information in massive data in web. Some of the tools that are available for data extraction and mining are DataMelt, Apache Mahout, Weka, Orange and Rapid Miner for enhancing web data extraction efficiency. This survey on bio inspired methodologies can be extended to parameter tuning and controlling is another big strategy that can be implemented, in addition to convergence speed up.

Residential buildings at coastal zone of Egypt face a great shortage in ventilation and thermal comfort, although it has a good orientation to the north. The research focused on Marsa Matrouh city because it is a poor community that has the privilege of sea view. So the research goal is to apply passive natural techniques to apply thermal comfort in this region to decrease the high rise temperature, the IPCC reports stated that there will be high rise temperature for this region as a results of climate change scenarios, for this reason the research aimed to upgrade the existed residential building to cope with this expected high temperature in natural passive way, also it is a good sample for implementing national architecture identity to achieve sustainability by using wooden shatter, wind capture and double glazing. In this research we proved that the optimum affordable natural ventilation technique is the using of double glassing and wooden overhang above each window, this suggested system allowed the air flow to be sucked in order to reduce internal temperature and energy consumption inside any residential buildings. Also the research verified the efficiency of this system by using soft computing technique (Design builder) for measuring the quantities of air flow, solar energy, carbon dioxide emissions, temperature and energy consumption. We aimed to optimize the suggested system to create a new methodology for thermal comfort at coastal zones to solve the high rise temperature issue.

The implementation of the PV system and its integration into the grid has been increased. In this process some power quality issues arise i.e. harmonics, voltage sags / surges, interruptions, flickers, transients, and this is due to non-linear loads, arc furnaces, frequent starting / stopping of electric motors, oscillating loads and interactions of different semiconductor devices. Within these interharmonics is one of the emerging power quality issues in grid-connected photovoltaic (PV) systems. Based on previous case studies and field measurements, evidence of interharmonic emission from maximum power point tracking is one of the leading causes of interharmonics in PV inverters. In this regard, MPPT parameters such as sampling rate and perturbation step size have a strong impact on the interharmonic characteristic of PV system, and to overcome these problems, a mitigating solution has been previously proposed , namely modifications of the MPPT algorithm so as to randomly select the sampling rate between the fast value and the slow value. By implementing this technique with an artificial neural network controller for the control of the inverter. With the proposed method, the voltage perturbations of the DC-link voltage as well as the harmonics of the grid currents are reduced and the performance of the MPPT and PV system has been increased. The performances of the proposed system has been validated on a MATLAB / SIMULINK software environment.

Published: February 2021

This research presents a novel mechanism to convert a conventional100-cc four stroke driven engine into a 2 stroke compressed air driven engine without doing any modifications in the cam shaft. This allows for a faster valve operation & also helping the existing engines to be converted into air driven engines with removal of intake and exhaust manifold and also provides a platform to curb the growing menace of air pollution by using the existing old engines to be used as air driven engine. Also, cycle of operation of the Air Engine has been representedon P-V diagram and theoretical efficiency has been calculated which is a function of pressure ratio and temperature, and comes out to be around 80 percent (@ Prr. Ratio of 10& Temp of 550K). Variation of rpm with percentage valve opening is seen at different pressure ratios and the maximum speed of the engine (after doing said modifications and running through compressed air)is observed to be 1573 rpm at a pressure of 9 bar with the developed mechanism for the existing 4 stroke maestro engine.
