Authors: Méndez R , Fernández J A. , Yáñez E A.
Published: August 2019

Con el objetivo de evaluar cómo afecta la aplicación de diferentes dosis de urea sobre la producción de materia seca (MS) y la composición nutricional del “pasto estrella”, se realizó un ensayo aplicando tres niveles de fertilización nitrogenada: T0: testigo (0 kg/N/ha), T1: 40,5 kg/N/ ha, y T2: 81 kg/N/ha. La parcela donde se aplicaron los tratamientos presentaba una pastura de C. plectostachyus (Pilger), con 15 años de implantada y nunca fertilizada, utilizada para pastoreo directo con altas cargas. Se utilizó un diseño en bloques completos al azar, con tres tratamientos y tres repeticiones, aplicando el fertilizante al inicio del trabajo, luego de un corte de emparejamiento. Los cortes se realizaron en el mismo año, los días 23/04, 14/05 y 16/06. A partir de las muestras se obtuvo la producción de MS y en el laboratorio se efectuó la determinación de proteína bruta (PB) y fibra detergente neutro (FDN). La fertilización nitrogenada del “pasto estrella” produjo un aumento de la producción de MS, de hasta el 40% para todo el período analizado, siendo mayor a 25% en el primer corte. La concentración de PB aumentó aproximadamente un 20% con la aplicación de nitrógeno al inicio del otoño, manteniendo este efecto durante 2 meses, luego de lo cual desapareció. La respuesta fue mayor para T1. La concentración de FDN no fue afectada por la fertilización nitrogenada, aunque se observó menor FDN en el primer corte, para todos los tratamientos. La combinación de mayor concentración de PB y menor de FDN, implica una mejoría en la calidad nutricional de la pastura en el período inicial post-fertilización.

Published: August 2019

El objetivo de la investigación fue determinar la prevalencia de coccidios en pollos de un municipio mexicano. Se tomaron muestras de 97 aves en 17 localidades y se recabaron datos para conocer la cantidad de aves por unidad, el tipo de alimentación, la causa de muerte, la época de mayor mortalidad y la realización de controles antiparasitarios en las 40 unidades visitadas. Se confirmó la presencia de ooquistes de Eimeria sp en 65 muestras, con prevalencia del 67,01% y niveles de infestación bajos, medios y altos (46, 10 y 9 casos). Hubo correlación entre hembras versus control de parásitos (p≤0,05), nivel de infestación versus causa de muerte (p≤0,05) y machos versus época de muerte (p≤0,05). El odds ratio indicó que las hembras son más susceptibles que los machos a contraer coccidios (1,87, p=0,1883). Se concluye que la prevalencia del protozoario en aves de unidades de traspatios en Salamanca es alta y está relacionada con el control parasitario, la época del año y el sexo de las aves. Además, comparadas con los machos, las hembras fueron más susceptibles a contraer coccidios.

Texture profile analysis of organic sweetpotato (Ipomoea batatas) cultivars as affected by different thermal processing methods
Authors: NWOSİSİ Sochinwechi , NANDWANİ Dilip , RAVİ Ramasamy
Published: August 2019

Different processing methods particularly
thermal treatments would impact the potato texture distinctly thus
understanding the influence of different thermal treatments on textural
characteristics of sweetpotato is needed. Six varieties of sweetpotato were
grown on the organic farm and subjected to three thermal treatments (baking,
pressure cooking and open cooking). Baking was done in an oven. Pressure
cooking was done with a pressure cooker and open cooking was done using a
vessel of water. Textural parameters were recorded with a texture analyzer.
Objectives were to evaluate the impact of different thermal processing
techniques on textural properties of sweetpotatoes and to generate the texture
profile analysis of cooked potatoes. Cohesiveness
(0.08-0.12%), gumminess (1.96-54.71) and chewiness (0.89-45.39) were highest in
baked treatments while hardness (61.24-475.55N) and resilience (0.02-0.11%) were
highest in open cooked treatments. Hardness, gumminess, chewiness and
resilience reduced with pressure cooking. Based on these results desirable
sensory properties can be optimized to maximize consumer acceptance.
Population change and distribution of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in strawberry greenhouses
Authors: GOKKAYA Sevgi , KARACA İsmail
Published: August 2019

Plant
protection has an important place among problems related to strawberry
cultivation. Red spider mites and thrips are the main pests observed on
strawberries, and among these, the most important for Antalya province is Frankliniella occidentalis (Pergande)
(Thysanoptera: Thripidae).

This study was performed in 2017 and
determined the population change and in-greenhouse distribution of Frankliniella occidentalis with direct counts on flowers and blue traps
in three strawberry greenhouses in Serik county in Antalya province. The
research was completed in three different greenhouses, with 25 blue sticky
traps in the 1st greenhouse with 4 da size and the 2nd greenhouse with
3.5 da size and 15 traps in the 3rd greenhouse with 2.5 da size.

Traps
were collected each week, with the numbers of thrips recorded. On dates when
the traps were changed, the thrips found on plants were counted by examining
ten flowers on three plants below or close to the blue sticky traps by eye or
with a loupe with counts performed until the day of harvest.

At the end of the study, the pest
population reached a certain level from the start of flowering in November in
the three greenhouses, and then fell in the middle of December. From the middle
of December, the population began to increase and this increase continued until
the strawberries were harvested. The number of pests per trap varied from 0.6
to 1904.2. When the whole production season is considered, the mean pest numbers
per trap in the three greenhouses were 287.2, 72.3 and 271.27 thrips/trap. The
number of pests per flowerhead varied from 0.0 to 2.5. When the whole
production season is considered, the mean numbers of pests per flowerhead in
the greenhouses were 0.26, 0.08 and 0.16 thrips/flowerhead.

In light of the data obtained in
the study, and considering the economic damage threshold value recommended by
previous research results, it was concluded there is no need for chemical
intervention against F. occidentalis in the region.

Debunking the Stanford Prison Experiment
Authors: Le Texier Thibault
Published: August 2019

The Stanford Prison Experiment (SPE) is one of psychology’s most famous studies. It has been criticized on many grounds, and yet a majority of textbook authors have ignored these criticisms in their discussions of the SPE, thereby misleading both students and the general public about the study’s questionable scientific validity. Data collected from a thorough investigation of the SPE archives and interviews with 15 of the participants in the experiment further question the study’s scientific merit. These data are not only supportive of previous criticisms of the SPE, such as the presence of demand characteristics, but provide new criticisms of the SPE based on heretofore unknown information. These new criticisms include the biased and incomplete collection of data, the extent to which the SPE drew on a prison experiment devised and conducted by students in one of Zimbardo’s classes 3 months earlier, the fact that the guards received precise instructions regarding the treatment of the prisoners, the fact that the guards were not told they were subjects, and the fact that participants were almost never completely immersed by the situation. Possible explanations of the inaccurate textbook portrayal and general misperception of the SPE’s scientific validity over the past 5 decades, in spite of its flaws and shortcomings, are discussed.
On the heterogeneity of people's (dis)honest behavior along two dimensions: Cost of lying and cost of acquiring information
Authors: Barcelo Hélène , Capraro Valerio
Published: August 2019

This paper studies lying in a novel context. Previous work has focused on situations in which people are either fully aware of the economic consequences of all available actions (e.g., die-under-cup paradigm), or they are uncertain, but this uncertainty cannot be cleared in any way (e.g., sender-receiver game). On the contrary, in reality, people oftentimes know that they will have a chance to lie, they are initially uncertain about the economic consequences of the available actions, but they can invest resources (e.g., time) to find them out. Here we capture the essence of this type of situations by means of a novel decision problem. Two experiments provide evidence of four empirical regularities regarding the distribution of choices, and suggest that participants vary along two dimensions: the moral cost of lying, and the cost of investing time to find out the payoffs associated to the available actions. Taking inspiration from these observations, we introduce a model that is consistent with the main empirical results.
SIMULATION MODELLING IN THE STRUCTURAL GRAVITY PROSPECTING
Authors: Anikeyev S. H. , Bahriy S. M. , Hablovskiy B. B.
Published: August 2019

In accordance with the purpose of geophysical exploration, the gravity data interpretation is aimed at prospecting mineral resources which is based on the study of the geological cross-section structure. The task of quantitative interpretation, which uses methods of gravity modeling and gravity inversion, is the modelling of a gravity field (gravity modeling) and of a density structure of geological environments (gravity inversion). The article presents the definition and steps of the gravity data modelling technique. This technique is based on the construction of an informal sequence of equivalent solutions. The technological and geological features of methods for modelling the density structure of complex geological environments are given; among them geological content, consistency with a priori data and the subordination of modelling to geological hypotheses are important. The topicality and methods of simulation modelling are outlined. The purpose of simulation modelling is to study the properties of gravity inversion in the general formulation, as well as to evaluate the degree of detail and reliability of the methods and technologies of gravity modelling, which claim to be an effective solution to geological problems. The example of structural simulation testing of the methods of informal sequence of equivalent solutions and its computer technologies shows that a complex interpretation of seismic and gravity measurements data enables the creation of detailed density models of structural cross-sections. The ways of increasing the veracity of gravity data modelling of structural cross-sections have been studied. It is revealed that the best approximation of the regional background is an inclined plane which approximates the observed field of gravity according to characteristic pickets over the research areas that are better studied. The increase in the veracity of modeling can also be achieved by rebuilding the near side zones in the structural type models in an interactive process of solving structural gravity inversion problems. Substantive modeling depends primarily on the experience of the interpreter since computer technologies for gravity modeling and gravity inversion are merely an interpretation tool.
FORECASTING CURRENT HYDROCARBONS AND HYDROCARBONS CUMULATED BY THE PRODUCTION WITH THE USE OF THE PROBABILISTIC-STATISTICAL MODELS
Authors: Boiko V. S. , Mishchuk B. M.
Published: August 2019

In the course of time any well, no matter how efficiently it was exploited and how rationally formation energy was used, stops blowing-out (flowing). Consequently, there appears a need to switch to artificial lift well operation methods and in both cases there is a need to predict the change of the parameters of the well operation, namely the change of flow rate.
Nowadays, to predict the flowrate, the logarithmic dependence is mainly used, but it does not always describe accurately the nature of the change in the amount of produced oil. In the design of the development of “new” oil and gas fields the numerical methods based on computer geological and industrial models took a prominent place. These methods provide an acceptable (for now) and the most reliable technological parameters of the development of hydrocarbon accumulation but on condition of  the availability of complete and satisfactory accurate information. This gives the opportunity to build a probable digitized geological model of the reservoir.  Such a model should be gradually clarified for the time of drafting  the next design document.
There wasn’t a lot of information with satisfactory accuracy about the “old” developed accumulations and it was not necessary to specify the set of parameters for analytical design. Therefore, it is almost impossible and economically unprofitable to build a modern geological model for them. It is only possible to get approximately the real overview of the depletion of oil reserves and to evaluate promising parameters of the development of deposits.
But, for both “new” and “old” fields there is a need to explore deposits additionally at the final stages of development and to evaluate the nature of their behavior in future.
It proves the importance of predicting the well flow rate and, overall, the fields development parameters at a mature production stage concerning both “new” and “old” fields according to the actual statistics of field development. Having studied the history (retrospective), it is possible to conclude about the further development of the basic production data (perspective) without great time and labour input. Automatically  the characteristics of the system implemented in the prospect and development technologies are taken into  account.

The article deals with the research of the potential of oil-and-gas content within the Western Ukrainian oil and gas region.  The main directions and ways of increasing oil and gas production are determined. Consequently, the discovery of new hydrocarbon fields is the major direction to boost oil and gas production. The issue of the discovery of new oil and gas fields is suggested to divide into the following directions: a search for oil and gas fields at shallow depths (short-term prospect), a search for oil and gas fields at mid-depths and a search for oil and gas fields at great depths (the main prospects of increasing oil and gas production). The geological and geophysical data were thoroughly analyzed throughout structural and tectonic units within the Western region of Ukraine with the aim of substantiating the prospects of their oil-and-gas content and introduction of new directions of oil-and-gas exploration. The prospects of oil-and-gas content of the Neogene and the Mesozoic deposits of the exterior of the pre-Carpathian depression and flysch of the interior of the pre-Carpathian depression are provided. The prospects of oil-and-gas content of the Cretaceous and the Paleogene deposits of folded Carpathians are characterized. The promising directions for further oil-and-gas exploration within indicated tectonic elements of Carpathian region are identified; the top priority project sites are suggested. Wildcat drilling and further oil-and-gas exploration are strongly recommended for all identified project sites. The research has identified the most promising exploration project sites. All of them are illustrated with appropriate maps and cross-sections. Thus, the most promising ones at shallow depths (up to 2000 m) are the following ones: South-Slyvkinske, Anhelivka, Hoshiv and Verkhnii Hutyn elevations. At mid-depths there are Pechenizhyn, Kliuchiv, Uhilnia and Boratychi elevations. At depths over 4000 m there are the following ones: Horodyshche structure, Posada, Dubliany, South-Lopushnia, Biskiv, Sloboda-Dolyna and Mizhrichchia elevations, Pidrezhzhia and Dobromyl-Strilbychi structures. The assessment of the resource potential of identified exploration project sites was done.
THE PREDICTION OF STATIONARY MODES OF OPERATION OF GAS SUPPLY SYSTEMS BY THE METHOD OF INTEGRAL COEFFICIENTS

Published: August 2019

The authors present the methods of generating the system of the integral coefficients of influence for gas transmission systems aiming at the estimation of the parameters of its work on stationary operating modes. Each change of the technological parameters of the operation mode at the input of the gas transmission system will necessarily cause the reaction of the system which will manifest itself in changing the corresponding parameters at its output. Obviously, the parameters of the input and output of the system are interconnected by a complex system of equations, the implementation of which requires certain time costs and gathering additional information about the technical and hydrogasdynamic states of the system at each moment. Under the conditions of incomplete loading of the gas transmission system, which involves frequent changes in its operation modes, the accomplishment of the task is not always possible. It is suggested to create a system of integral coefficients of influence which characterize the ratio of input and output information in different stationary modes, and formally submit it in a matrix form. The processes characterized by integral coefficients of influence implicitly contain the technological parameters of the gas pipeline (length, diameter, hydraulic resistance coefficient, heat transfer to the environment, etc.) which can not always be determined with sufficient accuracy by the deterministic methods. The suggested methodology involves the creation of simple and effective methods of predicting which allow estimating the state of the gas pipeline by the costs and pressures at the inputs and outputs of the system, that is, by the operational data that are being monitored. On the basis of the proposed methodology, it is suggested to create an operational system that will allow managing the modes of operation of the main gas pipeline in cases of frequent changes in pumping volumes. When changing the technological scheme of the gas transmission system, there is a need to adapt the integral coefficients of influence. The application of the proposed methods is illustrated by the example of the main gas pipeline Soyuz.

Abstract:  An experimental-based design; analyze physical model for daylight spaces is an experimental based design approach by using natural lighting. This experiment is based on applied models of skylight conditions in the field. The goal of this study is to identify configurations of model prototype models by using natural lighting optimally, then to describe their natural lighting through draw light and to measure the intensity of light through photometry. The results of this modeling experiment are several configurations that form the optimal model ing by using natural light through how much light intensity can get into a room. The prototype model is sized 7.2m x 8.4m x 5m by performing several configurations. The configuration alternatives include ten roof configuration, wall opening and type of material used. Based on the results of experiments, the characteristics of the intensity of natural light that get into a room are strongly influenced by the size and position of the opening area. In addition, using clerestory provides greater light intensity than using vertical windows. The impact of the intensity of the light is increasing a good visual interest for users.Keyword: physical model, natural lighting, daylight spaceAbstrak: An experimental-based design; analyze physical model for daylight spaces merupakan sebuah pendekatan perancangan berbasis eksperimen melalui pemanfaatan pencahayaan alami.

Abstract: The use of siger elements is found in commercial and government buildings in the city of Bandar Lampung. The existence of the siger element in the building is widely used after the issuance of the mayor's regulation that every commercial building and government in the city of Bandar Lampung must use the siger element. The lack of understanding about the preservation of local culture and architectural design of buildings makes the use of siger elements seem compelling and careless. This condition can be triggered because of the existence of regional regulations which in its formulation do not consider the perceptions of the local community about the use of the Siger element and the incomplete information in the existing regional regulations. The analysis that will be used in this study is an analysis of public perceptions about the use of siger in buildings. In this study, it was revealed how the perceptions of the people of Bandar Lampung about the use of siger elements in buildings. By knowing the perception of the Bandar Lampung community about the use of the siger element in the building, it is hoped that this study can be used as a recommendation in policy making to preserve local culture through building architectural design. The results of the study found 88% of respondents agreed with the use of siger elements in buildings and 12% of respondents said they did not agree.Keyword: Perception, Siger, BuildingAbstrak: Penggunaan elemen siger banyak ditemui pada bangunan-bangunan komersial dan pemerintah di Kota Bandar Lampung. Keberadaan elemen siger pada bangunan marak digunakan setelah dikeluarkannya peraturan walikota bahwa setiap bangunan komersial dan pemerintah yang berada di Kota Bandar Lampung harus menggunakan elemen siger. Kurangnya pemahanan tentang pelestarian budaya lokal dan desain arsitektural bangunan menjadikan penggunaan elemen siger terkesan memaksa dan asal-asalan. Kondisi tersebut dapat dipicu karena keberadaan peraturan daerah yang dalam perumusannya tidak mempertimbangkan persepsi masyarakat lokal akan penggunaan elemen siger dan kurang lengkapnya informasi dalam peraturan daerah yang ada.Studi ini dilakukan untuk mengetahui persepsi masyarakat Bandar Lampung tentang penggunaan elemen siger pada bangunan. Analisis yang akan digunakan dalam studi ini adalah analisis persepsi masyarakat tentang penggunaan siger pada bangunan. Pada studi ini diungungkapkan bagaimana persepsi masyarakat Bandar Lampung tentang penggunaan elemen siger pada bangunan. Dengan mengetahui persepsi masyarakat Bandar Lampung tentang penggunaan elemen siger pada bangunan diharapkan studi ini dapat digunakan sebagai rekomendasi dalam pembuatan kebijakan untuk melestarikan budaya lokal melalui desain arsitektur bangunan. Hasil studi didapatkan 88% responden setuju dengan penggunaan elemen siger pada bangunan dan 12% responden menyatakan tidak setuju.Kata Kunci: Persepsi, Siger, Bangunan
