The present study focused on observation of effect of potassium dichromate as standard toxicant on feeding activity of D. magna. Isolated feeding suppression was measured as fluorescence intensity of ingested microbeads by daphnids and expressed as its feeding rate (EC50FI). We calculated the sub-lethal feeding suppression endpoints for 1, 2, 3, 4 and 5 hours exposure in potassium dichromate and compared these values with EC50 concentration of immobilization test of D. magna. The most close to immobilization (EC50)result was obtained as for 4 as well for 5 hours exposure time; however 4 hs exposure was chosen as more adequate exposure time for our design of feeding suppression bioassay.
Cooperative trading of a price-maker wind power producer: A data-driven approach considering uncertainty
Authors: Qureshi Rizwan , Aziz Saddam , Bu Siqi , ahmad sadiq , Zhang Rongquan , Li , Gangqiang
Published: August 2021

This paper presents a novel framework for cooperative trading in a price-maker wind power producer, that
participates in the short-term electricity balance markets. In
this framework, market price uncertainty is first modeled using
a price uncertainty predictor, consisting of ridge regression
(RR), nonpooling convolutional neural network (NPCNN), and
linear quantile regression (LQR). RR is employed to select the
correlated features to the corresponding forecast day, NPCNN
is employed to extract the nonlinear features, and LQR is
employed to estimate the price uncertainty. Then, an improved
firefly algorithm (IFA) is proposed to solve the optimization
problem. IFA uses the adaptive moment estimation method to
improve the convergence speed and search for the global solution.
Finally, the Shapley value is employed for the profit distribution
of cooperative power producers. Illustrative examples show the
effectiveness of the proposed framework and optimization model
A fast data-driven topology identification method for dynamic state estimation applications
Authors: Gotti Davide , Ledesma Pablo , Amaris Hortensia
Published: August 2021

This paper proposes a fast topology identification method to avoid estimation errors caused by network topology changes. The algorithm applies a deep neural network to determine the switching state of the branches that are relevant for the execution of a dynamic state estimator. The proposed technique only requires data from the phasor measurement units (PMUs) that are used by the dynamic state estimator. The proposed methodology is demonstrated working in conjunction with a frequency divider-based synchronous machine rotor speed estimator. A centralized and a decentralized approach are proposed using a modified version of the New England test system and the Institute of Electrical and Electronics Engineers (IEEE) 118-bus test system, respectively. The numerical results in both test systems show that the method demonstrate the reliability and the low computational burden of the proposed algorithm. The method achieves a satisfactory speed, the decentralized approach simplifies the training process and the algorithm proves to be robust in the face of wrong input data.
Modeling the Evolution of Trap States with Thermal Post-deposition Treatments in Sol-gel Indium Zinc Oxide TFTs
Authors: Chatterjee Neel , Weidling Adam M , Ruden P. Paul , Swisher Sarah
Published: August 2021

Metal oxides have been investigated for use in displays and wearable electronics, owing to their high mobility in the amorphous state. In solution-processed oxide thin-film transistors, post-deposition thermal processing significantly change the film’s transport properties, and is essential for high-performance devices. The mobility, bias stability and trapping-detrapping related hysteresis are improved with higher processing temperatures, which is generally attributed to decreased localized states which act as electron traps. Here we develop a model to validate that post-deposition processing indeed changes the density and properties of the localized states. We obtain good agreement between this model and the experimental data measured from sol-gel indium zinc oxide TFTs. When the processing temperature increases from 300 to 500 0C, the model indicates that the trap state density in the bulk semiconductor and at the interface decrease by a factor of 5 and a factor of 3, respectively. Furthermore, the localized states become shallower, and the band mobility increases at higher processing temperatures.
Reliability-Aware Design of Spike-Event Neuromorphic Circuits
Authors: Shaik Jani Babu , Picardo Siona Menezes , Singhal Sonal , Goel Nilesh
Published: August 2021

Very Large Scale Integration (VLSI) based
neuromorphic circuits also known as Silicon Neurons (SiNs) emulate the
electrophysiological behavior of biological neurons. With the advancement in
technology, neuromorphic systems also lead to various reliability issues and
hence making their study important. Bias Temperature Instability (BTI) and Hot
Carrier Injection (HCI) are the two major reliability issues present in VLSI
circuits. In this work, we have investigated the combined effect of BTI and HCI
on the two types of integrate-and-fire based SiNs namely (a) Axon-Hillock and
(b) Simplified Leaky integrate-and-fire circuits using their key performance
parameters. Novel reliability-aware AH and SLIF circuits are proposed to
mitigate the reliability issues. Proposed reliability-aware designs show
negligible deviation in performance parameters after aging. The time-zero
process variability analysis is also carried out for proposed reliability-aware
SiNs. The power consumption of existing and proposed reliability-aware neuron circuits
is analyzed and compared.
A Stochastic Dynamic Programming Model for Hydropower Scheduling with State-dependent Maximum Discharge Constraints
Authors: Schäffer Linn , Helseth Arild , Korpås Magnus
Published: August 2021

We present a medium-term hydropower scheduling model that includes state-dependent environmental constraints on maximum discharge. A stochastic dynamic programming algorithm is used to enable modelling of nonconvex relationships in the problem formulation. The model is applied in a case study of a Norwegian hydropower system with multiple reservoirs. We find that the maximum discharge constraint significantly impacts the water values and simulated operation of the hydropower system. A main finding is that the nonconvex characteristics of the environmental constraint is reflected in the water values, implying a nonconvex objective function. Operation according to the computed water values is simulated for cases with and without the environmental constraint. Even though operation of the system changes considerably when the environmental constraint is included, the total electricity generation over the year is kept constant, and the total loss in expected profit limited to less than 0.8%.

Published: August 2021

It is said that Shia does not believe in Al-Qur'an that is available today, but we find that the Al-Qur'an that was printed by the Shia is the same Al-Qur'an which is printed elsewhere. Therefore, this study aims to explain the essence of Shia’s belief in Al-Qur'an that is currently in the hands of the Muslims and also the roots of that belief. The method used in this research is descriptive analysis namely by examining classical and modern books particularly the books of Shia’s scholars as the main source to explain and answer the problem formulations in this study. The results of this study indicate that Shia does not believe in Al-Qur'an that exists today. They are forced to read and perform its laws until the emergence of Al-Qaim, which is Imam Mahdi Al-Muntazhar in their version which would carry "the original al-Qur'an." There are two roots of this belief those are to legitimize the doctrine of Al-Wilayah or Imamat of Ahlul Bait and to deny the virtues of the companions.

This study aims to identify the extent to which the historical roots of the Shafi'i school in Indonesia in terms of its arrival and spreading and to determine the extent of the influence of the Shafi'i school in the lives of Muslims in Indonesia and whether it plays a role in the codification of laws in Indonesia? The researcher employed the historical inductive approach and the descriptive-analytical approach. Among the results of the research are that the entry of the Shafi'i school in Indonesia was accompanied by the entry of Islam in it by Arab traders from the Arabian Peninsula - or the Indies (Malibar and Gujarat). Based on reliable documents, I can confirm that Islam entered Indonesia in the seventh century AD (first century in Hijriyah), yet began to spread strongly in the tenth century AD through the emergence of Islamic kingdoms in the archipelago which adopted the Shafi'i school as the official school of the state. The influence of the Shafi'i school is evident in Indonesia on the educational curriculum taught in the era of the Islamic kingdoms and the era of independence in several institutions and Islamic boarding schools. The Shafi'i school also shows its influence in the law of Islamic governance in Indonesia, although it is limited to matters of marriage, inheritance, and waqf.

Published: August 2021

Surah An-Nisa is one of the longest madaniah surah, and is one full of provisions of sharia laws that govern all matters both internal and external ones for Muslims. Among the prominence of this noble surah is that it tells a lot about important things related to women, household, family, country, and social life. In this surah, there are commands and prohibitions in various matters. The purpose of this study was to extract imperative sentences related to family life and then briefly identify the rules that became the base for these commands. The researcher employed an inductive and analytical approach by extrapolating Surah Al-Nisa, taking imperative sentences related to family life, and explaining the law which is concluded from it. Researcher finds, among the most important of the most important ones are as follows: understanding the meaning of al-amr (command) which is a request to do something in the form of superiority. There are two types of amr: direct and indirect. The number of amr related to the family in the surah is seventeen.
منهج فقهاء الشافعية في عرض الفروق الفقهية
Authors: Akhmad Hanafi Dain Yunta
Published: August 2021

Several scholars of fiqh of the Shafi'i School in presenting fiqh issues used the method of deciphering aspects of the differences between legal issues that had a similar picture but had differences in terms of the law, which was later known as al-furuq al-fiqhiyyah. Since the beginning of the writing of al-furuq al-fiqhiyyah, there had been some literature that discussed it specifically or which specializes it in a sub-discussion. However, the researcher found in this literature that there are significant differences in the method of presentation among the authors. Because of that, it is considered important to formulate a separate method of approach as a general standard to recognize the character of scientific works on al-furuq al-fiqhiyyah. In this study, the researcher used the inductive istinbat method of approach, by inducing possible and representative works of literature related to al-furuq al-fiqhiyyah in the Shafi'i School. This study found that the Fuqaha of Shafi'i school used four ways in presenting the discussion of al-furuq al-fiqhiyyah, namely: Describing the discussion of al-furuq al-fiqhiyyah in one separate literature, describing it in the literature related to al-farq (differences), and al-istisna' (exception), describing it in the literature that specifically discusses a particular problem or issues, and describes it in the literature that simply inserted a discussion of al-furuq al-fiqhiyyah as a complement.

Allah SWT. has bestowed Muslims with many advantages and specialties that are not given to other people, among the greatest gifts that Allah 'azza wajalla has given to the Islamic law as well as differentiating it from the previous ummah, namely the existence of relief and eliminating distress according to the passages of the Qur'an and sunnah show this. This study aims to explain the nature of the Rukhshah Syar'iyyah (reliefs) and some of the problems associated with it and to explain the strongest opinion of the differences of opinion of the scholars. The method used in this research is the descriptive analysis method. The results of this study indicate that Rukhshah is a shar'i law that changes from difficult to easy due to an age that causes it to take this relief while still having the original legal cause. There are also some important issues related to the Rukhshah which have an impact on contemporary life. Amongthese are that the Rukhshah is a branch, not the original law and that an immoral person cannot choose an existing Rukhshah, as well as not looking for loopholes to always get one.

Hadith is the second source of Islamic law after the Qur'an, obedience to the Messenger of Allah is also obedience to Allah SWT. The Prophet's Sunnah came to strengthen, explain and add new laws to the Qur'an. The scholars have paid great attention to preserving the sunnah, this is evidenced by their work in the science of hadith muṣṭalaḥ, where they put down and establish rules for the acceptance and rejection of hadiths regarding mind and sanad. One of the most famous works in the science of muṣṭalaḥ hadith is al-Manẓūmah al-Baiqūnīah. This study aims to get to know al-Manẓūmah al-Baiqūnīah and its position among scholars in general and those who are involved in the science of hadith in particular as well as the intensity of the ulama's attention to this manmahūmah. This research uses inductive and deductive descriptive methods, by extrapolating information related to the description and biography of al-Baiqūnī and what is related to the description of his book (al-Manẓūmah al-Baiqūnīah). In his research, the researcher achieved many results, including al-Baiqūnī does not have sufficient biography to show his identity, this manẓūmah is one of the most succinct scientific observations in the science of muṣṭalaḥ hadith. Even though it is concise, this manzumah is highly accepted by those who are busy and deepen the science of hadith even though it contains criticism from some scholars. This is evidence of the great concern of the scholars for this manẓūmah.

Revisión sistemática de literatura teórica sobre métodos de evaluación de impacto para evaluar políticas públicas
Authors: Rivadeneira Vildoso Christian
Published: August 2021

Los programas y las políticas públicas se diseñan e implementan con el objetivo de cambiar algún comportamiento o aspecto de la vida de una persona, como su educación, sus ingresos, su alimentación, etc. Esta implementación se basa en la teoría del cambio para lograr sus objetivos. Sin embargo, determinar si estos programas o políticas públicas logran los impactos o resultados esperados es una labor que a menudo no es abordada por los implementadores de las políticas públicas. La evaluación de impacto de las políticas públicas es una acción fundamental dentro de la gestión pública, pues permite obtener información sobre los impactos que tienen dichas políticas o programas en la población beneficiaria y así poder estudiar la posibilidad de ampliar el alcance, modificar, sugerir cambios o detener la ejecución. En esta revisión sistemática se evaluaron 22 estudios sobre evaluación de impacto. La temporalidad de los estudios evaluados va desde el año 1983 hasta el año 2017. Uno de los principales hallazgos está referido a la importancia de estimar un contrafactual creíble que permita identificar de manera adecuada el impacto de la aplicación de una determinada política pública. Otro de los aspectos a resaltar es que la metodología para evaluar una determinada política pública depende de los datos con los que se cuenta y de las características de la intervención. Finalmente, los modelos econométricos utilizados para estimar los impactos no son, en ningún caso, modelos rígidos. Mucho dependerá de la habilidad y la creatividad del investigador para plantear una propuesta metodológica que cumpla con el objetivo planificado.

Transit for a better and more equitable urbanity
Authors: Karppi Ilari , Sankala Iina
Published: August 2021

Nordic welfare states once sought to provide their citizens with affordable and healthy housing conditions by planning compact residential areas. For a variety of reasons, this model is now in a major rupture. Strong domestic and international migration to 4-6 urban regions transforms Finland’s spatial setup. The entire process entails major challenges for urban design. Expanding urban structures constitute a massive source of greenhouse gases and are often deemed dysfunctional for reaching goals such as social sustainability, better public health or even individually perceived quality of life. Transit-oriented development (TOD) is one of the attempts to tackle these challenges. It holds a major promise for better and more equitable urbanity, but this assumes that the entire dynamics of urban development and how transit and better accessibility are related to it will be re-thought. This paper is based on case-study data from Tampere city region and its on-going light rail transit (LRT) construction process as an example of the current TOD thinking. It also makes references to comparable or otherwise interesting international LRT processes as discussed in planning journals or based on the authors’ own observations and fieldwork.
Symbolic Geographies, Nordic Inspirations, and Baltic Identities
Authors: Dremaite Marija
Published: August 2021

"In Finland we really felt architecture", Lithuanian architect Vytautas Čekanauskas used to say remembering his first study trip to Finland in 1959. Impact of Nordic design is often emphasised when discussing Baltic  design of the State Socialist period. When new residential districts in the 1960s were built among the trees in existing pine forests, as happened in Āgenskalna Priedesin Riga, Mustamäe in Tallinn, and Lazdynai in Vilnius, then Tapiola in Helsinki was most often cited as inspiration. Indeed, as opportunities for tourist travel and foreign exchange programs increased in the late 1950s, the Soviet Architects' Association began to organize professional delegations that included several representatives from each of the Baltic republics, dispatched on fact-finding missions to Finland. But why Nordic concept of regionalism became so important in the formation of the Baltic post-war modernism ? In the paper it is argued, that Finnish modern architecture, that was experienced at first hand during the study trips, was perceived as an acceptable model for the Baltic architects who wished to belong to the international community of modern architecture, yet retaining a national idiom and being distinctive within the USSR.

Erfolgsfaktoren für grenzüberschreitende Transporte
Authors: Haldemar Christoffer
Published: August 2021

Seit Jahren konzentriert sich die Lieferkettenindustrie darauf, sich selbst zu optimieren, indem sie Kosten, Zeit und Ressourcen reduziert. Faktoren wie ausreichende Flexibilität und Agilität zur Bewältigung von Krisen werden in der Unternehmensstruktur allerdings nur selten erkannt. Die COVID-19-Pandemie hat vielen Akteuren entlang der Lieferkette ihre Schwachstellen aufgezeigt und der ohnehin schon volatilen Logistikbranche zusätzliche Hindernisse in den Weg gelegt. Die unterschiedlichen Entwicklungen und Verläufe der Pandemie in den einzelnen Ländern Europas sorgten bei grenzüberschreitenden Transporten für enorme Schwierigkeiten: Dazu gehörten teils starke Schwankungen bei Transportvolumina und -kosten, aber auch abweichende Lieferzeiten und -routen.

Der Schutz der Beschäftigten vor berufsbedingten Krebserkrankungen stellt eine zentrale Herausforderung für die im Arbeitsschutz Tätigen dar. Verantwortlich für die Mehrzahl der tödlich verlaufenden berufsbedingten Krebserkrankungen ist die Exposition von Beschäftigten gegenüber krebserzeugenden Gefahrstoffen am Arbeitsplatz, deren Folgen sich erst Jahre später zeigen. Es darf nicht übersehen werden, dass auch heute noch krebserzeugende Gefahrstoffe an Arbeitsplätzen auftreten. Diese stellen trotz ständiger Fortschritte im Bereich des Arbeitsschutzes ein Gefährdungsrisiko für Beschäftige dar. Der Gefahrstoff-Check der Gemeinsamen Deutschen Arbeitsschutzstrategie (GDA) ist ein niederschwelliges Angebot an alle Akteurinnen und Akteure im Arbeits- und Gesundheitsschutz eines Unternehmens, um vorausschauend und effektiv die Gefährdungen für die Beschäftigten durch krebserzeugende Gefahrstoffe am Arbeitsplatz zu erkennen und nachhaltig wirkungsvolle Schutzmaßnahmen treffen zu können. Dabei sollen insbesondere kleinere und mittlere Unternehmen (KMU) mithilfe der Selbsteinschätzung beim Einstieg in die Gefährdungsbeurteilung unterstützt werden.

Published: August 2021

Spätestens seit dem Mücksch-Urteil 2012 [1] ist der angemessene Sicherheitsabstand von Störfallbetrieben ein sehr präsentes Thema für Betreiber von Störfallanlagen, Kommunen und potenzielle Bauherren in der Nachbarschaft. Stand in den ersten Jahren die Ermittlung der Abstände im Vordergrund, stellt sich heute immer mehr die Frage, welche Entwicklungen in Betriebsbereichen und innerhalb des ermittelten Sicherheitsabstands möglich sind.
Quaderförmige flüssigkeitsgefüllte Metallbehälter und -wannen unter Erdbebenbelastung
Authors: Gehrig Hans
Published: August 2021

Dieser Beitrag behandelt kastenförmige Behälter und Wannen, die einer Bodenbeschleunigung aus Erdbeben unterliegen und in denen eine Flüssigkeit gelagert ist. Nach Vorstellung verschiedener Bauformen werden drei Berechnungsverfahren aus der Literatur im Hinblick auf ihre Praxistauglichkeit kurz diskutiert. Danach wird ein auf einer indischen Erdbebenrichtlinie basierendes Berechnungsverfahren vorgestellt, das nach Ansicht des Verfassers sehr praxistauglich ist, da bei ihm nur wenige Vorwerte berechnet werden müssen, deren Ermittlung dazu noch übersichtlich aufbereitet ist. Abschließend werden zwei Beispiele durchgerechnet, ein geschlossener Behälter zur Lagerung von Heizöl und eine Auffangwanne unter einer Maschine. Die derzeit geltende deutsche Erdbebennorm DIN 4149 Ausgabe 2005 wird spätestens wohl im Jahr 2022 durch den nationalen Anhang zum Eurocode 8 abgelöst, wodurch sich zum Teil erheblich höhere Lasten ergeben werden. Hierauf wird beim Heizölbehälter kurz eingegangen.

Die Bewässerung von Park- und Sportrasen muss Anforderungen der Nutzer und des Umweltschutzes genügen. Technische Regelwerke, kommunale Satzungen, Nachhaltigkeitsaspekte und das Mikroklima vor Ort sind zu berücksichtigen. Zum Wassermanagement gehört ein Konzept, bei dem der Ressourceneinsatz von Trinkwasser und Betriebswasser nach den ökologischen und ökonomischen Möglichkeiten der Region erfolgt. Das gilt vor allem in Trockenperioden.
Teil 2: Die Sauerstoffgrenzkonzentration von Methan, Ethan und Propan
Authors: Vogel Hans-Herbert
Published: August 2021

Die Sauerstoffgrenzkonzentration ist das Minimum des Sauerstoffanteils in einem mit Inertgas verdünnten Brennstoff/Luft-Gemisch, in dem gerade keine Explosion (Entflammen) mehr möglich ist. Diese sicherheitstechnische Kenngröße hängt vom Druck und von der Temperatur ab. Basierend auf dem Programm Cantera von Goodwin und der Reaktionskinetik der NUI Galway wird das im ersten Teil des Beitrages beschriebene Modell auf die Berechnung der Sauerstoffgrenzkonzentration von Methan, Ethan und Propan ausgedehnt. Die Genauigkeit des Modells ist vermutlich höher als die der spärlich vorhandenen Messwerte.
Effects of temperature and repeat layer spacing on mechanical properties of graphene/polycrystalline copper nanolaminated composites under shear loading
Authors: Huang Chia-Wei , Chang Man-Ping , Fang Te-Hua
Published: August 2021

In the present study, the characteristics of graphene/polycrystalline copper nanolaminated (GPCuNL) composites under shear loading are investigated by molecular dynamics simulations. The effects of different temperatures, graphene chirality, repeat layer spacing, and grain size on the mechanical properties, such as failure mechanism, dislocation, and shear modulus, are observed. The results indicate that as the temperature increases, the content of Shockley dislocations will increase and the maximum shear stress of the zigzag and armchair directions also decreases. The mechanical strength of the zigzag direction is more dependent on the temperature than that of the armchair direction. Moreover, self-healing occurs in the armchair direction, which causes the shear stress to increase after failure. Furthermore, the maximum shear stress and the shear strength of the composites decrease with an increase of the repeat layer spacing. Also, the shear modulus increases by increasing the grain size of copper.

The paper states the gradual revival of tourism, both in Ukraine and in the world. That is why we believe that tourism, especially in the western and southern regions of our country can become a significant driver of economic development of local communities. For the rapid and successful development of the tourism industry in Ukraine, it is necessary to find internal reserves to increase demand for domestic tourism products, increase ways to meet consumer demands for content, diversity and quality of tourism and recreation services. It is determined that the system of management of the tourism industry in the context of decentralization in Ukraine is disorganized, built on lobbying principles, consists of different in number and quality of officials, has insufficient funding and misuse of allocated funds. The importance of creating a decentralized management mechanism in the conditions of decentralization, which will be effective even with minimal funding of the tourism industry, different number of employees in this field and will ensure a high level of their professionalism. It is proposed to create tourist departments at the regional and local levels; training and retraining of specialists-managers, who in connection with the position will perform the assigned powers in the field of tourism. A separate area is the improvement or change of the law on tourism adopted in 1995, which does not fully meet modern realities and requires comprehensive changes that would meet the interests and modern needs of society. We believe that it is very important that tourism should be planned on a comprehensive basis, taking into account all aspects of legislation relating to other sectors that have a direct or indirect impact on it.
