Published: October 2020

Wheat is one of the most important cereal crops of the world and is a staple food for about one third of the world’s population. Despite the significant area of wheat production in the country, the mean national yield 1.3 t ha-1 is 24% below than mean yield for Africa and 48% below than global mean yield. A field experiment was carried out at Senegal and Selmamer during 2014 cropping season to determine the effects of sowing methods and seed rate on yield of bread wheat (Triticum aestivum L.). Treatments were two sowing methods namely row planting and broadcasting with six  Seed rate (kg/ha): 125, 150, 175, 200, 225 and 250 kg/ha.The experimental was laid in randomized complete block design (RCBD) with thee replications. The study result depicted that sowing method and seed rate had brought significant effect on the   yield of bread wheat. The maximum grain yield of 3.9 t ha-1 and the minimum 2.7 t ha-1 were obtained from seed rate of 125 kg ha-1 and 200 kg ha-1 respectively. And the maximum grain yield of 3.5 t ha-1 was obtained from row planting and the least 3.13 t ha-1 was recorded from broadcast method; from these output we can conclude that, using of seed rate of 125 kg ha-1 and row planting is advisable for bread wheat production in the Senegal and Senmamer kebeles and their vicinities to increased wheat production and productivity.
FOOD SUPPLY CHAIN PLAYERS: WITH DIRECT AND TRADITIONAL CHANNELS
Authors: Arunfred N. , Kinslin D.
Published: October 2020

We study a dual channel supply chain in perishable agricultural products. In which one channel is producer (farmer) sells the produce directly to the customer and the other channel is about transfer of produce to different channel players and reach the final customer. Consumers choose the purchase channel based on price, availability, accessibility, product quality, trust-ability and service qualities. The producer decides the price of the direct channel and the intermediaries decides both price and order quantity in the traditional method. We show that the difference in problem faced by the producers’ of the two channels plays an important role in determining the existence of dual channels in equilibrium. For the study Erode and Kanyakumari districts were chosen purposively. A sample of 80 farmers was selected randomly who are involved in both of the channels. In the case that the producer and the retailer coordination and to follow a centralized decision approach, we find that a direct channel will be an optimum solution for improving the overall effectiveness. Our results show that an increase in retailer’s service quality may increase the producer’s profit in dual channel and a larger range of consumer service sensitivity may benefit both parties in the dual channel. The results suggest that both the channel have problem and the optimum solution lies in between two channels.

Published: October 2020

There has been rapid development of mobile communication technology (MCT) in the last decade with Botswana having a tele density of 168 %, hence the need to find out if MCT is effectively used in agriculture. A sample of 36 commercial farmers answered a questionnaire. All commercial farmers in the study own at least one form of MCT device, the most common being mobile phone. In spite of ownership of such devices, commercial farmers do not adequately use MCT in their farm work as on average 53 % said they have used it in one form or another. The perceived impact of MCT in commercial farming is also not satisfactory as on average 50% of the farmers in the sample answered in the negative. The unsatisfactory use of MCT by farmers can be mitigated by having discussions with farmers and showing them the benefits of using MCT in their farm work.

Authors: Rupilu Krisostomus
Published: October 2020

Pulau Pasir Timbul merupakan lokasi peneluran 3 jenis penyu yaitu Chelonia mydas, Eretmochelys imbricata dan Lepidocheys olivacea. Keberadaan penyu untuk bertelur selalu mendapat ancaman dari luar, baik dari manusia atau alami berupa predator dan lingkungan yang mempengaruhi penyu menuju lokasi peneluran. Salah satu faktor lingkungan yang mempengaruhi perubahan rona lingkungan peneluran adalah gelombang. Penelitian ini bertujuan untuk mengetahui pengaruh faktor lingkungan seperti gelombang sebelum musim peneluran penyu terhadap rona pantai dan tingkah laku peneluran di pulau Pasir Timbul. Penelitian ini menggunakan metode observasi dengan melakukan pengamatan terhadap gelombang laut, rona pantai dan tingkah laku peneluran penyu. Pengamatan gelombang dilakukan pada musim barat sebelum musim peneluran dengan membagi lokasi menjadi 4 transek sesuai arah mata angin. Pengamatan rona pantai dan tingkah laku peneluran penyu dilakukan pada saat musim peneluran pada bulan april  sampai mei. Hasil analisa energi gelombang pada pulau Pasir Timbul memiliki energi gelombang tinggi pada T2 berkisar antara 211,07–1332,09 joule/m2. Energi gelombang yang besar dipengaruhi oleh tiupan angin yang berhembus pada saat musim barat. Besarnya energi gelombang pada T2 mengakibatkan perubahan garis pantai, dimana mengalami abrasi hingga daerah vegetasi dengan kemiringan mencapai 90o. Penyu yang muncul pada bagian barat pulau terhalang (barrier) untuk mencapai lokasi peneluran, perubahan rona pantai ini berdampak pada tingkah laku penyu untuk mencapai lokasi peneluran. Besarnya energi gelombang yang terjadi  selama musim barat pada lokasi T2, menjadi penyebab perubahan rona pantai dan tingkah laku peneluran penyu pada bagian barat pulau. Perlu melakukan penelitian lanjutan mengenai pengaruh musim timur terhadap perubahan rona pantai pulau.

One type of marine ornamental fish that can be developed through cultivation is betok Ambon fish. Cultivation of this fish is quite profitable, and easy to maintain. To maintain the sustainability and sustainability of Betok Ambon fish farming, one way to take is to understand and know the growth and reproduction aspects of this type of fish through the provision of inferent hormones appropriately. Review article This aims to reveal the role of the inferent hormone on the aspects of reproduction and growth of Betok Ambon fish. Reproduction is the reproduction process in living things including Betok Ambon fish. The number of eggs produced by Betok Ambon fish varies between 900 and 3,500. Inferent hormone is one type of reproductive hormone that functions to spur and accelerate the level of gonad maturity in animals including fish. The determination of the inferent hormone dosage is based on the determination of the inferent dose in fish, generally around 10 mg - 80 mg or about 0.1 ml - 0.8 ml. Generally, fish that are given inferent hormone at a dose of 40-60 mg / l can increase the gonad maturity index by 25%, in betok Ambon fish by 30%. Inferent hormone doses around 20-40 mg can increase the growth and survival of ambon betok fish.

Дизайн печатных СМИ: эволюция понятия «композиция»
Authors:   МГУ им. М.В. Ломоносова, факультет журналистики, Галкин Станислав
Published: October 2020

Будущее печатных СМИ, в частности газет, вызывает большие опасения. Композиция периодического издания является одним из важных факторов визуализации контента номера газеты или журнала. В статье на основе анализа исследований теорий композиции делается вывод, что журнал и газета в настоящее время имеют так мало общего, что рассмотрение композиции как единого целого в различных типах изданий нецелесообразно.
«La più curiosa» regata in onore del duca di York (Venezia, 4 giugno 1764)
Authors: Perocco Daria
Published: October 2020

This essay analyses one of the most sumptuous regattas of the Serenissima Republic: it was organised in honour of the Duke of York, brother of George III of England, during his stay in Venice on June 4, 1764. Among the many races, the women’s race, in which the most famous rowers of the time took part, stands out. It was also celebrated in poetry: after that day, the poetic text is published here for the first time.
D’Annunzio dall’una all’altra prosa
Authors: Gibellini Pietro
Published: October 2020

In the particular form of a letter, this critical analysis focuses on the prose writing of Gabriele d’Annunzio, from the novelistic and romance story to the exploration of shadows and personal recherche, between elzeviro and fragment. In the analysis, the attention goes to the studies dedicated over the years to the topic by Pietro Gibellini, also referring to the contributions by Ilaria Crotti on the same subject: not a retrospective, solipsistic look on individual contributions, but an attempt to compose them in a summary, in order to follow the turning point, or rather the turning points, that led the author to move from one genre to another.
Il viaggio del testo
Authors: Ricorda Ricciarda
Published: October 2020

Italo Calvino described his journey in the United States between 1959 and 1960 in different texts, from the first draft in “Diario americano 1959-1960”, included in Eremita a Parigi, to some journalistic correspondences and then to a volume, Un ottimista in America, which he had planned to publish but abandoned after correcting the second drafts. The essay aims to analyse the different stages of writing, following the passage from the first draft to the volume, that has been recovered and published in 2014.
Lungo i futuri possibili del poliziesco
Authors: Zava Alberto
Published: October 2020

In its rigorous and highly normative framework, the detective story often allows productive analyses on the functioning of its mechanisms and on the role of its elements when it is subjected to structural infringements in order to obtain specific narrative effects. The Minority Report (1956), science fiction story by Philip K. Dick, represents a particular case of ‘science fiction detective story’, a cross between science fiction and the context of the detective investigation, in which the knowability itself of reality and criminal actions change radically, thus providing the starting point for some considerations on how some key elements of the detective story are modified (or how, despite the different approach, they keep their role and function) in a context that represents a substantial and basic infringement of the genre scheme.

Disease mapping seeks to represent the risk of a disease. This paper focuses on the spatial analysis of risk for pandemic COVID-19 in Europe and the Mediterranean. Morbidity and mortality data for 54 countries in ratio format were used. Two hypotheses were considered, the first one is that the data are homogeneous and the second one is that the ratios are defined in a heterogeneous manner requiring the stratification on the basis of covariables and the methodology of Jenks’ intervals. Spatial risk models were applied as well as methods for the representation of clusters. The results show that the best representation is obtained with the Poisson-Gamma Model under stratification. The variations in the ratios are due to the individual policies of each country for the management of the pandemic. The cluster analysis shows that there is a high mortality process in Eastern Europe. The behavior of the pandemic should be evaluated in the space-time process as well as in other heterogeneous and highly unequal regions.
Nietzsche: de la decadencia en el trabajo a la ascendencia en el capitalismo
Authors: Rincón Orozco Cristian David , Londoño Betancourt Orlando
Published: October 2020

Objetivo: evidenciar elementos para defender la idea de que el trabajo en el contexto capitalista es, desde Nietzsche, decadente, pero que, a pesar de ser decadente, es posible la vida ascendente en él. Para ello, este artículo explica qué entendía Nietzsche por decadencia, cuál fue la causa de esta decadencia, algunas de sus consecuencias y, en especial, por qué el trabajo en el contexto capitalista es una consecuencia más de la decadencia de la cultura. También explica cómo, a pesar de estar inmersos en un contexto decadente, es posible la vida ascendente. Para esto, se analiza el papel del dueño de empresa y de los empleados de ella. Metodología: este estudio procede metodológicamente mediante el análisis filosófico de conceptos. Así, se aplica el método genealógico de Nietzsche, con el que se enfrenta la visión restrictiva de la ética, según la cual pareciera como si ésta partiese de supuestos previos, absolutos, no demostrables y dogmáticos. El pensamiento de Nietzsche, entonces, constituye no sólo un referente teórico, sino también metodológico para abordar este tema. Resultados: la filosofía de Nietzsche tiene implicaciones sobre el capitalismo y la vida empresarial contemporánea. Conclusiones: la vida ascendente dentro del contexto capitalista es muy difícil de alcanzar y solo la logran unos pocos seres excepcionales, que tienden al Übermensch.

Published: October 2020

The success of organizing a traditional work of art cannot be separated from the important role of data and information obtained from the public in general, and viewers or art connoisseurs in particular. This information is an indicator that can be used to measure the amount of public attention to traditional arts, which is an effort to promote traditional cultural arts. Data and information related to traditional artworks were obtained from filling out the instruments that were distributed to the public online to produce an opinion form that contained a complete description with a discussion containing the aesthetic of the artwork. Opinion data is needed as a measure of progress and preservation of a work of art. The linguistic measurement of opinion can be solved using fuzzy methods in a cryptic form that can be weighted. In this study, the authors tested the audience opinion text mining application on the presentation of traditional cultural artworks using fuzzy clustering using the functional testing method (Black box testing). Through this test will be discussed related to the menu or module to produce information.
Existence and stability results of relaxation fractional differential equations with Hilfer--Katugampola fractional derivative.
Authors: ALMALAHI Mohammed , PANCHAL Satish K.
Published: October 2020

In this work, we present the existence, uniqueness, and stability result of solution to the nonlinear fractionaldifferential equations involving Hilfer-Katugampola derivative subject to nonlocal fractional integral bound-ary conditions. The reasoning is mainly based upon properties of Mittag-Leffler functions, and fixed-pointmethods such as Banach contraction principle and Krasnoselskii's fixed point theorem. Moreover, the gener-alized Gornwall inequality lemma is used to analyze different types of stability. Finally, one example is givento illustrate our theoretical results.

Fetal head-down posture may explain the rapid brain evolution in humans and other primates: an interpretative review
Authors: Macionis Valdas
Published: October 2020

Evolutionary cerebrovascular consequences of upside-down postural verticality of the anthropoid fetus have been largely overlooked in the literature. This working hypothesis-based, narrative review postulates that the rapid evolution of the human brain has been promoted by fetal head-down position due to maternal upright and semi-upright posture. Habitual vertical torso posture is a feature not only of humans, but also of monkeys and non-human apes that spend considerable time in sitting position. Head-down position of the fetus may have caused physiologic craniovascular hypertension that stimulated expansion of the nourishing intracranial vessels and acted as an epigenetic physiological stress, which enhanced neurogenesis and eventually, along with other selective pressures, led to the progressive anthropoid brain enlargement. This article collaterally opens a new insight into the conundrum of high cephalopelvic proportions (i.e., the tight fit between the pelvic birth canal and fetal head) in phylogenetically distant lineages of monkeys, lesser apes, and humans. Low cephalopelvic proportions in non-human great apes could be accounted for by their energetically efficient horizontal nest-sleeping and consequently by their larger body mass compared to monkeys and lesser apes that sleep upright. It can be further hypothesized that brain size varies in anthropoids according to the degree of exposure of the fetus to postural verticality. The supporting evidence for this postulation includes a recent finding that in fossil hominins cerebral blood flow rate increased faster than brain volume. The approaches for testing the hypothesis include experimentation with avian embryo position in vitro, comparative cephalometry of vertex-breech twins, and Doppler assessment of the fetal cerebral circulation in maternal upright and horizontal posture. The current report opens a perspective for further related research on circadian postural behavior, obstetrics, and fetal postural cranial hemodynamics in humans and other primates. It may also be possible to expand the introduced hypothesis into a universal theory of epigenetically enhanced embryonic/fetal cerebral neurogenesis as a driver of evolutionary encephalization.
