Endless skies and open seas – how birds and fish navigate
Authors: Spiecker Lisa , Leberecht Bo , Langebrake Corinna , Laurien Malien , Apte Shambhavi Rajendra , Mouritsen Henrik , Gerlach Gabriele , Liedvogel Miriam
Published: June 2021

Every year, billions of animals leave their home range and start seasonal migrations in order to find more favorable resources and to escape harsh environmental conditions. These round trips often span thousands of kilometers. To successfully navigate along their route, animals rely on various external references. While landmarks and celestial cues like stars or the sun are easy to imagine as guidance on these journeys, using the geomagnetic field for orientation is more elusive. The geomagnetic field is an omnipresent cue, which can be sensed and relied upon by many animals, even when visual cues are sparse. How magnetic fields can be perceived seems to vary between birds and fish. While birds seem to use a mechanism based on the quantum mechanical properties of electron spins, fish may have evolved a compass similar in its function to the technical devises developed by humans. How these mechanisms work precisely and how they are integrated are research questions addressed in SFB 1372.

Published: June 2021

Marine mussel-inspired polydopamine (PDA) coatings show excellent hydrophilicity and substrate-independent adhesion ability, but low stability, especially in a harsh environment such as strong acid or strong base, significantly restricts their applications. In this work, we prepare a novel superhydrophilic and underwater superoleophobic coating based on a modified PDA. Diglycidyl resorcinol ether (DGRE) polyethyleneimine (PEI) and iron ions were incorporated into PDA to strengthen the cross-linking and coating durability. By using three chemically inert hydrophobic membranes, polytetrafluoroethylene (PTFE), poly(vinylidene fluoride), and polypropylene, as substrates, we showed that PDA/PEI/DGRE-coated membranes had a water contact angle (CA) of 0° and underwater oil CA above 157°, and their underwater oil SAs were <7°. The coating is durable against both physical and chemical damages including ultrasound and heat treatments, as well as acid/alkaline etching. After ultrasound treatment in water for 60 min, and heating treatment for 3 h, or acid/alkaline etching for 3 h, the coated PTFE membrane still showed water CAs of ∼0° in air and underwater oil CAs of ∼150°. The coated membranes can efficiently separate oil-in-water emulsions, even in strong acid and base environments. The water flux was above 1500 L m−2 h−1, and the oil rejection was above 99%.
Maximum cross section method in the filtering problem for continuous systems with Markovian switching
Authors: Averina Tatyana A. , Rybakov Konstantin A.
Published: June 2021

New solution algorithms of optimal filtering problem are proposed for systems with random structure and continuous time. This problem consists in estimating the current state of system based on the results of measurements. The mathematical model of the system includes nonlinear stochastic differential equations whose right-hand side determines the structure of the dynamic system or mode of operation. The right-hand side may vary at random time moments. The number of structures of the system is assumed to be finite and the process of changing the structure to be Markov or conditionally Markov. The state vector of such system consists of two components, namely, a vector with real coordinates and an integer structure number. The law of change of the structure number is determined by the distribution of the random time interval between switchings with a given intensity dependent on the state of system.
A diffusion–convection problem with a fractional derivative along the trajectory of motion
Authors: Lapin Alexander V. , Shaidurov Vladimir V.
Published: June 2021

A new mathematical model of the diffusion–convective process with ‘memory along the flow path’ is proposed. This process is described by a homogeneous one-dimensional Dirichlet initial-boundary value problem with a fractional derivative along the characteristic curve of the convection operator. A finite-difference approximation of the problem is constructed and investigated. The stability estimates for finite-difference schemes are proved. The accuracy estimates are given for the case of sufficiently smooth input data and the solution.
KCu(SeO4)Cl(H2O)2, a first copper chloride selenate
Authors: Siidra Oleg I. , Markovski Mishel R.
Published: June 2021

A first copper chloride selenate was obtained upon attempted preparation of a selenate analog of chlorothionite. The new compound is monoclinic, P21/c, a = 7.1833(5) Å, b = 11.7784(8) Å, c = 8.2419(6) Å, β = 91.083(2)°, V = 697.20(8) Å3, R
1 = 0.033. KCu(SeO4)Cl(H2O)2 has no structural analogs and adds to the small family of transition metal selenate halides. The CuO3(H2O)2Cl strongly distorted octahedra share common O–O edges thus forming dimeric units with a Cu–Cu distance of 3.49 Å. Dimeric units and SeO4 tetrahedra in KCu(SeO4)Cl(H2O)2 share common O atoms to produce unique [Cu(SeO4)Cl(H2O)2]− chains. We discuss further perspectives of the selenate halide family and expected differences in crystal chemistry of sulfate and selenate halides.

Authors: McBurnie Alistair J. , Dos'Santos Thomas
Published: June 2021

This review provides a definition for multidirectional speed (MDS) and evaluates its technical and mechanical underpinnings. This review explores each component of MDS while considering unique aspects of youth physiology and epidemiology. With a theoretical understanding of MDS, practitioners will be more informed on the planning and periodization of MDS training methods in soccer. MDS comprises linear speed, change of direction speed, curvilinear speed, contextual speed, and agility, which each have distinct physiological, biomechanical, and neurocognitive distinctions that can either be differentiated or harmonized to optimize training.

Published: June 2021

Concurrent training, commonly acknowledged as a training method where strength and endurance training are completed complementary to each other, is a strategy often implemented in endurance cyclists' and runners' programs to improve physiological determinants of success such as exercise economy. Although concurrent training methods and strategies have been examined to a large extent in endurance cyclists and runners, literature examining optimal concurrent training methods to improve physiological variables in long-distance triathletes is minimal, leaving optimal programming relatively unknown. This practical applications paper identifies and outlines current concepts and considerations regarding concurrent training for long-distance triathletes including mechanisms contributing to improved performance, muscle and movement patterns used, exercise selection, load, velocity of movement, scheduling, frequency, and duration of training. Common misconceptions related to concurrent training are also identified and practical considerations for the application of concurrent training for coaches, athletes, and other professionals to improve all 3 disciplines of triathlon are discussed.
Klor u vodi – primjer kemijske ravnoteže i reaktivnosti
Authors: Raos Nenad
Published: June 2021

Klorna voda nije, jednostavno, otopina klora u vodi, nego složena otopina koja sadrži elementarni klor, Cl2(aq), klorovodičnu (HCl) i hipoklorastu kiselinu (HOCl) uz trikloridne ione (Cl3−) i možebitno zaostalu kuhinjsku sol, NaCl. Sve te komponente stoje u međusobnoj kemijskoj ravnoteži. U radu je opisana kratka povijest kemije i tehnologije klora, prikazane su ravnotežne reakcije u njegovoj vodenoj otopini te primjena HOCl kao dezinfekcijskog sredstva uz navođenje njezinih kemijskih i fizioloških učinaka. U posljednje je vrijeme razrijeđena klorna voda (50 – 100 ppm) postala popularna kao dezinfekcijsko sredstvo (“elektrokemijski aktivirana voda”, ECA, i sl.). Iako se ECA jednostavno priprema, elektrolizom razrijeđene vodene otopine NaCl, veliku pozornost treba posvetiti njezinoj čistoći te režimu skladištenja kako bi ostala dugo vremena stabilna.

Stoga je u radu dan pregled temeljnih vrsta maski za lice, pri čemu su uz pojašnjenje njihove primjenjivosti u svakodnevnoj uporabi među općom populacijom opisani bitni zahtjevi koji se na njih postavljaju, vrste materijala od kojih se izrađuju te u konačnici način njihove razredbe i označivanja, s posebnim osvrtom na važeću nacionalnu i europsku zakonodavnu te normativnu legislativu, propitujući pritom mogućnosti respiratorne zaštite.
Testicular swelling leading to a diagnosis of adrenocortical carcinoma – co-incidence or causation?
Authors: Batool Maria , Fennell David , Slattery David , Leen Eamon , Cormican Liam , Sreenan Seamus , H McDermott John
Published: June 2021

Adrenocortical carcinoma (ACC) is a rare malignancy with an incidence of 0.7–2.0 cases/million/year. A majority of patients present with steroid hormone excess or abdominal mass effects, and in 15% of patients ACC is discovered incidentally. We present a case of 30-year-old otherwise asymptomatic Caucasian male who presented with a testicular swelling. Subsequent imaging and investigations revealed disseminated sarcoidosis and an 11 cm adrenal lesion. An adrenalectomy was performed. Histological examination of the resected specimen confirmed an ACC and also demonstrated a thin rim of adrenal tissue containing non-caseating granulomas, consistent with adrenal sarcoid.

Learning points

This case highlights an unusual presentation of two uncommon diseases.

This case also highlights how separate and potentially unrelated disease processes may occur concomitantly and the importance, therefore, of keeping an open mind when dealing with unusual diagnostic findings.

We also hypothesize a potential link between the ACC and sarcoidosis in our patient.
Strategische Kostentransformation als Weg aus der Krise
Authors: Aydin Ümit , Müller Bernhard , Heggemann Xenia
Published: June 2021

Kostensenkung ist das Gebot der Stunde – und für viele Unternehmen angesichts der konjunkturellen Situation überlebenswichtig. Dabei hat die Mehrheit der Unternehmen bereits etliche Runden zur Kostensenkung durchlaufen – oft mit großem Aufwand, aber vielfach nicht mit entsprechendem Erfolg. Der Kostendruck darf aber nicht dazu führen, dass Investitionen in die Zukunft, das heißt in neue Technologie und die Erweiterung der Geschäftsfelder, eingebremst werden oder gar ausbleiben. Unternehmen laufen sonst Gefahr, sich durch ein eindimensionales Sparprogramm existenzielle Schritte in Richtung neuer Geschäftsmodelle zu verbauen, strategische Flexibilität einzubüßen und am Markt abgehängt zu werden. Ein Zielkonflikt, mit dem sich derzeit Führungskräfte in vielen Branchen konfrontiert sehen. Wie kann er gelöst werden? Anregungen für die Beantwortung dieser Frage gibt dieser Beitrag, welcher das Thema Kostentransformation von Strategie bis Ausblick auf Operationalisierungshebel beleuchtet.

El Señor Presidente y el vanguardismo surrealista
Authors: Ramírez Caro Jorge
Published: June 2021

El Señor Presidente es un texto vanguardista, no según la modalidad europea, sino según la vertiente híbrida surgida en América Latina. La novela utiliza recursos y estrategias discursivas del surrealismo para redimensionar las experiencias subjetivas de unos personajes envueltos por la atmósfera pesadillesca y demoníaca de la dictadura. Como texto híbrido mezcla lo ajeno (vanguardias europeas y cristianismo) y lo propio (cultura maya-quiché); y su confluencia posibilita la colisión de tres estéticas: la corriente realista (realismo y regionalismo), el mundo animista maya-quiché y las vanguardias (surrealismo).El Señor Presidente is a vanguard text, not in the European sense, but following the hybrid form appearing in Latin America. The novel employs resources and discourse strategies of surrealism to resize the subjective experiences of some characters enveloped in the nightmarish and demonic atmosphere of the dictatorship. As a hybrid text, foreign aspects (European vanguards and Christianity) are combined with their own (Mayan-Quiche culture); and their coming together leads to the collision of three esthetic codes: realist currents (realism and regionalism), the animist Mayan-Quiche world and the vanguards (surrealism).
Welding of thermally modified wood and thermal modification of the welded wood: Effects on the shear strength under climatic conditions
Authors: Vaziri Mojgan , Sandberg Dick
Published: June 2021

This work investigated how thermal modification affects the shear strength of welded joints under different climatic conditions. The order of the thermal modification, before or after the welding, was investigated for its effect on the shear strength of the welded wood. Two groups of thermally modified specimens were prepared in a laboratory kiln under controlled conditions, one thermally modified before welding and the other after welding of the specimens. The shear strength of the specimens were measured at four different moisture contents of 10%, 12%, 16%, and 18%, and the results for the two different approaches were compared. Moreover, observations of the X-ray computed tomography scanning and digital microscopy were used to study the density profile and the structural details of the welded joints. The results showed that thermal treatment of the wood either before or after welding had a negative influence on the shear strength, and the modes of failure of the joints in mechanical tests were in most cases brittle. In the weld interface of the wood modified before welding, a rigid material similar to charcoal was produced as a result of the further degradation of wood by welding pressure and frictional motion. Welding of wood before thermal modification, however, yielded thicker and more densified joints with less susceptibility to higher moisture variations than the joints obtained by welding the thermally modified wood.

Published: June 2021

The characteristics of Viper's bugloss (Echium vulgare) plant, its pharmacological properties, and extracts’ composition are presented in this study. Results of the literature analysis, data on the biologically active compounds and areas of use of this medicinal plant are summarized. Viper's bugloss (E. vulgare) is a species of flowering plant in the borage family Boraginaceae. It is native to most of Europe as well as western and central Asia. Viper's bugloss (E. vulgare) is a plant that has been utilized as food (honey), medicine, a poison, an oil, and as a dye and tannin-producing ornamental plant. Viper's bugloss (E. vulgare) is especially rich in pyrrolizidine alkaloids, flavonoids, phenolcarboxylic acids, sterones and naphthoquinones. In traditional medicine, Viper's bugloss (E. vulgare) is utilized as exhilarant and a mood stimulant. That is why one of the possible uses of this plant is considered to be treatment of depressive states. Like most representatives of Boraginaceae family, it has been insufficiently studied. No previous work quantifying flavonoids content of aerial parts of Viper's bugloss (E. vulgare) growing in Ukraine has been presented. Continuing the studies of this species, the aqueous and ethanolic extracts from Viper's bugloss (E. vulgare) aerial parts were obtained and their phytochemical composition was investigated. For the first time, the qualitative analysis of biologically active compounds in Viper’s bugloss’s extract as well as the quantitative analysis of flavonoids by aluminum chloride spectrophotometric method are reported. The experimental results showed that the total concentration of flavonoids was 2.59% in the extract. The maximum yield of extractives was found to be 16%. The obtained research data will be used in future investigations.
The mathematical description of dopamine electrochemical oxidation, accompanied by its chemical and electrochemical polymerization
Authors: Tkach Volodymyr , Kushnir Marta , Ivanushko Yana , Lukanova Svitlana , de Oliveira Silvio C. , Yagodynets Petro
Published: June 2021

The electrooxidation of dopamine is accompanied by its chemical and electrochemical polymerization, and in which either the monomer or the polymer may be oxidized to the respective quinonic form, was investigated from the theoretical point of view. Dopamine is one of the important neurotransmitters in human and mammal organisms. It is a precursor to epinephrine, which influences the cardiovascular, hormonal and renal functions. Its lack causes diseases like Parkinson, therefore, dopamine has been used as a drug for their treatment. On the other hand, its excess stimulates the sympatic nervous system yielding the metabolic disorders and even schizophrenia. Thus, the development of the rapid and accurate method for its concentration measurement is very important. Dopamine is very popular analyte in electroanalytical systems. The modified electrodes for its determinations have been developed by many researchers. Dopamine is widely used as a monomer for synthesis of a conducting polymer – polydopamine, whis is used as electrodes’ modifier in capacitors and in anticorrosive coatings. The electropolymerization of dopamine into polydopamine proceeds along with its traditional quinone-hydroquinonic oxidation. Both processes give their impact to the electrochemical behavior of dopamine during its electropolymerization. The mechanism’s complexity is also responsible for the electrochemical instabilities during electro-oxidation. In order to understand these instabilities it’s necessary to develop the mathematical model that is capable to describe the behavior of the system. It also helps us to esteem the influence of the electrochemical instabilities, by which it may be accompanied. The goal of this work is to describe an electrochemical oxidation and polymerization of dopamine that will provide an important connection between the electrochemical detection of biologically active compounds and their electropolymerization for electrode modification.

Proposta de modelo de gestão estratégica para instituições de educação básica confessionais
Authors: De Souza Alexandre , Carvalho Carlos Eduardo
Published: June 2021

Durante a maior parte da história do Brasil, os colégios confessionais consolidaram-se com uma proposta educativa baseada na formação integral da pessoa, sem preocupar-se com concorrência. Com a alteração da Lei de Diretrizes de Base, de 1996, que permitiu a entrada de grupos empresariais no setor educacional, muitos desses colégios fecharam as portas, diante da expertise em gestão dos novos concorrentes. A escola confessional precisou aprender a conciliar essa nova dimensão ao projeto pedagógico. Tendo em vista a importância histórica e social dessas instituições, o atual cenário da educação básica privada do Brasil e o escasso conhecimento sobre o assunto, este artigo propõe um modelo de gestão estratégica para uma Rede de Educação Confessional. Trata-se de um estudo de caso qualitativo. Os instrumentos de pesquisa utilizados foram: coleta de dados na sede da Rede, entrevistas semiestruturadas com os gestores e questionários com os diretores de escolas. Os resultados evidenciam a implantação de uma cultura de gestão estratégica na Rede e a atualização do modelo de gestão estratégica, a partir do Balanced Scorecard. Este artigo contribuiu com a discussão do tema da gestão estratégica em escolas confessionais, possibilitando a integração de elementos da gestão e da confessionalidade.
The impact of fundamental uncertainties on economic growth
Authors: Yalçinkaya Ömer , Çelik Ali Kemal
Published: June 2021

This paper addresses the impact of fundamental (economic, political and geopolitical) uncertainties on GDP growth of the world’s largest 20 economies (W-20) using the Cobb-Douglas total production function within the scope of the second-generation panel data methodology for 1990–2016. The aim of the paper is to explore whether these uncertainties lead to a contractionary impact on growth as suggested by the economic theory. The estimation results revealed that indeed this was the case. Our results also indicate that the global uncertainties led the economic growth rates of the selected countries to perform below their exact potential since the 2008 global economic crisis and to fail to attain an expected recovery during the process.
Companies' growth vs. growth opportunity: Evidence from the regular and alternative stock markets in Poland
Authors: Bolek Monika , Pietraszewski Piotr , Wolski Rafał
Published: June 2021

The article discusses the ability of potential growth measures calculated basing on market share prices to predict the future growth of the companies listed on the primary and alternative exchange markets in Poland. Analysing the Polish exchange market and dividing the sample of companies due to the markets they are listed – the Warsaw Stock Exchange Main Market or the NewConnect Alternative Market – brought conclusive results. Company growth measured as the growth of total assets, equity, sales and, what is the most important, earnings per share, is related to the growth opportunity measures and other factors taken into account in the tested models. The differences between the results for the two separate markets are evident and the relationship between growth opportunity measures and the future growth seems to be stronger for larger companies listed on the main market, while the NewConnect smaller companies’ growth is less predictable. We add to the theory of the growth prediction a modified approach by sampling companies according to the exchange they are listed that helps to solve the companies’ “growth puzzle” and supplement the growth theory in the field of factors affecting this process in different growth stages. The originality of the paper is reflected in the modified approach to the problem and distinguishing the stages of development of the company taking into account the Polish stock market.

Moreover, it employs the two countries' confidential diplomatic documents as primary sources. This article focused on the first part of the above period.
Hősköltemény a Moreai Krónikában. Geoffroy de Bruyères vitézsége
Authors: Török Ábel
Published: June 2021

A tanulmány annak a Moreai Krónikában ránk maradt egyedülálló irodalmi alkotásnak, középgörög „hőskölteménynek” eredetét és jellegzetességeit vizsgálja, amelynek főhőse a pelagóniai ütközetben vitézkedő Geoﬀroy de Bruyères.2 Bár a szakirodalomban egyetértés van abban, hogy az epizódnak valószínűleg népköltészeti háttere lehet, egyes kérdések – így többek között a fellelhető irodalmi áthallások, az intertextuális összefüggések és nem utolsósorban a (krónika)írói szándékok – nincsenek érdemben feltárva. A tanulmány elsőként a Moreai Krónika keletkezésének történeti hátterét mutatja be röviden, a történelmi ismertetést elsősorban a műben tárgyalt eseményekre szűkítve, majd Geoﬀroy de Bruyères személyét és a róla írt hősköltemény lehetséges irodalmi párhuzamait tekinti át, végül pedig a pelagóniai ütközet magyar vonatkozásaira tér ki. A függelékben továbbá megtalálható a közel másfél száz verssor irodalmi fordítása.

The study examines the origins and characteristics of a unique Byzantine ‘epic’ in the Chronicle of Morea : the description of the Battle of Pelagonia and the exploits of Sir Geoﬀroy de Bruyères. Although the professional literature agrees on that the episode is likely based on folk poetry and oral tradition, many questions (such as literary crosstalk, intertextual connections, the author’s intentions etc.) remain unanswered. The study presents the historical context of the Chronicle, examines the person of Sir Geoﬀroy de Bruyères and the potential intertextual relations of his epic, and analyses the Hungarian relations of the Battle of Pelagonia. The literary translation of the nearly 150 lines of the battle is attached in the appendix.
Middle Sarmatian Burial Complex from Opushki Necropolis, the Crimea
Authors:   Non-Profitable Foundation “Heritage of Millennia”, Shabanov Stanislav
Published: June 2021

The Necropolis of Opushki is located in approximately 15 km to the east from Simferopol, 2–2,5 km to the south-west from the village of Opushki of Mazanka Rural Settlement in Crimea. Illegal excavations have been conducted on the territory of the cemetery since 2002. More than 200 burials constructions were destroyed as a result of grave robbers actions on the territory of about 3 hectares. Scientific researches of the necropolis were conducted in 2003 – 2005, 2007, 2009, 2013–2014, 2016–2020. During this period, more than 300 burials of different types have been uncovered (crypts, simple pit graves, shaft-and-chambers graves, slab graves and cist tomb). Judging by excavated sites, the cemetery was in continuous use from the 1st century BC until the 4th century AD. Among the researched burial constructions there are crypts typical for the Late Scythian period, middle and late Sarmatian burials, crypts influenced by the Northern Caucasus Alans arriving in Crimea, cremation performed by German tradition. The paper is devoted to the middle Sarmatian paired burial in the grave № 233 excavated in 2018. The assemblage of grave goods from that grave is quite various and informative: bronze fibulae, bronze and iron bracelets, red slip pottery, beads. The chronology of the burial assemblage may be defined as the second half of the 1st – first half of the 2nd centuries AD. The funeral rite of paired burials is not typical for the tradition of individual burials in first centuries, although its features are found in the burial grounds of the Central and South-Western Crimea. This funeral rite is associated with the issues of family structure and social relations in the late Scythian society.
About Women’s Clothing with Decorated Sleeves from the Filippovka I Kurgan Cemetery
Authors:   Institute of Archaeology of the Russian Academy of Sciences, Okorokov Konstantin , Tregubov Vyacheslav ,   Orenburg Gubernatorial Museum of Local History
Published: June 2021

During the archaeological study of the Filippovka I kurgan cemetery, several burial complexes were revealed containing items related to women’s clothing. The article analyzes the burials where these items were found intact – burial 2 of kurgan 1 and burial 4 of kurgan 4. As a result of comparing the types of sewn-on elements and their positioning in the burial, a certain similarity between the complexes was found, so it’s possible to draw a conclusion about the general appearance of the female clothing from the kurgan cemetery. In addition to the gold stripes made in the animal style, fragments of beaded embroidery decorating the sleeves of one of the clothing elements were found in burial 2 of kurgan 1. Protomes of deer marching in a row were depicted using regular and small beads of different materials on the sleeves. The article contains a description of the best preserved figures. Also, the first explorer of the cemetery A. Kh. Pshenichnyuk discovered in kurgan 1 a cache with a large number of gold patches on clothes as well as other items made of precious metals. Typological and stylistic similarity with patches from the burials examined allowed the authors of the article to make an assumption about the similarity between clothing from the cache and the burials. Specific features of the early Sarmatian animal style appear in the gold patches of clothing and the lining of wooden bowls from the Filippovka I kurgan cemetery. This allows us to assume that the entire set of implements with the Philippian animal style was made by order and matching the taste of the early nomads.

Vegetative parameters of eight M3 (third mutant generation) lines of sesame were evaluated under rain fed condition. The seeds of the lines were sown alongside their respective controls using a randomized complete block design. The eight lines were generated from three parental stocks: NCRIBEN-04E (V1), NCRIBEN-01M (V2) and NCRIBEN-03L (V3). The three parental stocks were exposed to different doses of gamma irradiation from cobalt-60 source. 04E-550-G2-3 had the highest plant height (57.40) at the 6th week which was significantly different (P<0.05) from the three checks. 03L-450-G2-2 had the highest petiole length (12.45cm) which was significantly different (P<0.05) from the checks except check three (12.25cm) which was not significantly different (P>0.05). 03L-450-G1-2 had the highest number of leaves (91) and consequently highest number of branches (5.60). Although the number of leaves were significantly different (P<0.05) from Check three (54.60), there was no significant difference (P>0.05) between the number of branches and check three (5.40). The results obtained for vegetative parameters of M3 lines of sesame suggests that some of the genotypes could be used as potential parents for future breeding programmes aimed at improving sesame lines.

Food loss may occur in production, storage, transport, and processing, which are the stages of the value chain with the lowest returns. The current searching was done by the keywords in main indexing systems including PubMed/MEDLINE, Scopus, and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. The most important points challenging areas that represent opportunities for stakeholders to look into in China are, put in place suitable economic incentives to encourage restaurants to get more involved in the formal system, create a comprehensive regulation system to benefit all relevant stakeholders by clearly defining their respective roles and responsibilities, which is necessary for the proper functioning of the whole system. In China, the most important regulations, policies and plans are regulations on safety issues of food waste treatment, detailed countermeasures on organizing, educating, supervising, and inspecting the work on food waste reduction in China, and detailed plant for household waste collection and treatment, issued by Chinese government, state council, and ministry of environmental protection. Setting national goals, awareness-raising campaigns, strict and appropriate regulation, stakeholder engagement, biorefinery and food waste recycling to animal feed are important strategies for better waste management. The most important food waste management practices in China are source separation, animal feed, rendering, composting, co-digestion, anaerobic digestion, incineration, landfill, and etc. Understanding social factors influencing household behavior is utmost importance; public education and specific communication highly contribute to improve recycling.

Abstract Urinary tract infections are responsible for most human infections, these are caused by bacteria, fungi, protozoa and associated microorganisms. The goal of this study was to determine the rate of vaginal infection-causing agents in routine cytological exams and also to evaluate the characteristics of positive tested Pap smears. A retrospective documental with descriptive aspect research was performed in a Clinical Pathology laboratory from Maceió-AL. The results of the Pap smears exams for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp and HPV were arranged in a database as well as other data such as bacterial, protozoan, fungal and viral coinfections. The sample was composed by 18.645 women who have undergone Pap smear exams from 2013 to 2017. Of these analyzed exams, 27.4% in 2013, 10.9% in 2014, 10.6% in 2015, 15.2% in 2016 and 13.67% in 2017 were within normal range, however more than half of these exams presented some infections caused by unspecific or microbiological agents. By analyzing all the reports, 4.073 (21.84%) presented inflammations caused by some species of infectious agent with the following rate order: G. vaginalis and T. vaginalis. Furthermore, it was possible to confirm high rates of coinfection by and Candida spp. The rate of genital infections in this study highlights that there is a public health matter that must be controlled, which points a greater need for monitoring, guidance and actions towards greater awareness in order to prevent these problems.

Abstract Optimum planting arrangement is an important attribute for efficient utilization of available resources and to obtain high yield of cotton. Application of plant growth promoter and retardant on cotton in improved planting density are the innovative techniques in the establishment of more productive cotton crop. Therefore, we planned a field study to assess the role of bio-stimulant and growth retardant in the resource utilization efficiency of cotton cultivars planted under variable row spacing at Agronomic Research Area Bahauddin Zakariya University and Usmania Agricultural Farm Shujabad during Kharif 2012. Experimental treatments consisted of cotton genotypes viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and ultra-narrow row spacing (25 cm) with foliar spray of bio-stimulant (moringa leaf extract) and growth retardant (mepiquate chloride), either sole or in combination, keeping distilled water as a control. Exogenously applied MLE alone and MLE + MC significantly enhanced the number of squares, flowers and green bolls per plant leading to higher cotton seed and lint yield of CIM 598 cultivar cultivated under conventional row spacing. While application of MC alone and MLE + MC produced maximum micronaire value, fiber strength and fiber uniformity ratio of CIM 573 cultivar cultivated under conventional row spacing. The results suggested that application of MLE is a possible approach to enhance the cotton productivity and the use of MC to enhance the fiber quality attributes under conventional row spacing.

Abstract For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect of different protein-based feed on weight gain, standard growth rate (SGR), food conversion ratio (FCR), percent weight gain, food conversion efficiency (FCE), and protein efficiency ratio (PER) was studied. An increase was observed in the growth rate with an increase in protein concentration up to 45%. The fingerlings fed a 45% protein diet shown the highest growth, followed by 50%, 40%, and 35%. The SGR value was greatest for 45% protein diet (8.56) followed by 50% and 40%, while the least values were observed for 35% protein feed (1.57). The same trend was observed for FCE. The highest PER values was observed in fishes fed 45% protein-based feed (0.65) followed by 50% (0.56), 40% (0.38) and35% (0.17). The food conversion ratio was lowest for 45% protein diet (3.41), while the greatest for 35% protein feed (16.85). It was concluded that a 45% protein-based diet was the best feed formulation for higher production of Tor putitora. However, research on the same percentage of protein diet is recommended for yearlings.

Published: June 2021

Although board games and video games have been studied for decades in artificial intelligence research, challenging word games remain relatively unexplored. Word games are not as constrained as games like chess or poker. Instead, word game strategy is defined by the players’ understanding of the way words relate to each other. The word game Codenames provides a unique opportunity to investigate common sense understanding of relationships between words, an important open challenge. We propose an algorithm that can generate Codenames clues from the language graph BabelNet or from any of several embedding methods – word2vec, GloVe, fastText or BERT. We introduce a new scoring function that measures the quality of clues, and we propose a weighting term called DETECT that incorporates dictionary-based word representations and document frequency to improve clue selection. We develop BabelNet-Word Selection Framework (BabelNetWSF) to improve BabelNet clue quality and overcome the computational barriers that previously prevented leveraging language graphs for Codenames. Extensive experiments with human evaluators demonstrate that our proposed innovations yield state-of-the-art performance, with up to 102.8% improvement in precision@2 in some cases. Overall, this work advances the formal study of word games and approaches for common sense language understanding.
Restoration and development of listed heritage buildings in Kolkata, India
Authors: Ghosal Mainak , Ghosh Indranil
Published: June 2021

Kolkata in India has many historic houses with great architectural and engineering value, potentially serving as a perennial source of learning for India’s built-environment students. However, most are in a very poor condition with no public funding available for their refurbishment. While reuse of such heritage buildings is an important factor for sustainability, the Indian government has so far only given them heritage status. An example is Avery India’s former offices in central Kolkata, which are currently being refurbished by private developers. This paper discusses the engineering solutions applied and how period materials are being blended with modern construction methods.

Çalışma 1990’larda Güney Amerikalı bir grup düşünür tarafından geliştirilen dekolonyal

düşünceyi temsilcileri ve temel kavramları üzerinden Türkçede tanıtmayı ve

özgün bir tenkit üretmeyi amaçlamaktadır. Düşünce, sömürgeciliğin şeklen bitmesine

rağmen sömürülen toplumların güç, bilgi ve varlık noktalarında sömürgesel olageldiklerini,

bunun aşılabilmesi için 1492’den başlayarak tarihin yerli yerince anlaşılması,

Avrupa düşüncesinin kapsamlı bir eleştirisinin ortaya koyulması ve bilgi üretiminin özgürleştirilmesi

gerektiğini savlamaktadır. Quijano, Dussel ve Mignolo’nun önderliğinde

dekolonyalistler alternatif bir bakışı, tahakkümün muhtelif boyutlarını kavramayı ve değişimi

vadederken, hareketin Güney Amerika’yı merkezine alması, mevcut düzene somut

bir alternatif sunmaması ve eleştirdiği düzeni soyut bir düzlemde ele alması gibi hususlar

eleştiriye açıktır.
