Los forrajes son la base de la alimentación de bovinos de los sistemas de doble propósito en el trópico seco de la región costa chica del estado de Guerrero. El objetivo del estudio fue determinar la respuesta productiva del pasto Cayman a tres tipos de fertilización orgánica y química en la Costa Chicade Guerrero, en condiciones de temporal. Se realizaron cosechas a intervalos de 14 días, iniciando a los 20 días después del corte de uniformización, el cual fue a diez centímetros de altura. En cada cosecha se registró la altura promedio de 10 plantas, la acumulación de materia seca y la composición morfológica. La unidad de muestreo fue un cuadro de 0.45 m2. Los datos registrados para cada medición fueron analizados con el procedimiento MIXED de SAS (Versión 9.0 para Windows) para un diseño experimental en bloques completos al azar, en arreglo de medidas repetidas en el tiempo. En el rendimiento de materia seca de forraje por hectárea los cuatro tratamientos evaluados fueron iguales en todas las fechas de corte a excepción de la fecha tres (Tukey, P ≤ 0.05). En altura de planta el tratamiento químico fue superior a los tratamientos orgánicos en el cuarto y quinto muestreo (Tukey, P ≤ 0.05); sin embargo, en la última fecha de corte fueron iguales (Tukey, P ≤ 0.05). En la composición morfológica, la mayor acumulación de hoja en el tratamiento químico se encontró a los 50 días, mientras que para los tratamientos orgánicos se encontró a los 65 días. La fecha optima de corte para el pasto Cayman con fertilización química es a los 50 DDC y para los tratamientos orgánicos entre los 50 y 65 DDC.
The Economic Analysis of The Nigerian Fisheries Sector: A Review
Authors: ODİOKO Edafe , BECER Zehra Arzu
Published: March 2022

The fisheries sector is an essential aspect of the world economy sector in terms of employment, food security, enterprise development, foreign exchange earnings, and important in terms of the livelihoods of many rural people and nutrition. Over 10% of the world population are economically dependent on fisheries as a source of employment, of which the majority are females. In Nigeria, over 764,615 people are reportedly engaged in the fisheries sector. The fisheries sector contributed 0.5% to the national GDP in 2015. The Nigerian fisheries sector is dependent on the artisanal fishers that produce over 68% of the nation’s total domestic production. It is an indication that this sector is not well utilized and developed. Nigeria is the world’s fourth-largest importer of fish products in terms of volume. Nigeria total fish imports of about $1.2 billion and exports valued at $284,390 million in 2013, make Nigeria a net importer of fishery products. In 2019, a shortfall in fish supply of about 1.3 million metric tons was met through imports. Relevant figures indicated that the value of fish imports keeps increasing which has been attributed to the increasing growth rate of the Nigerian population. From 2006 – 2010, the NBS reports showed that fish was the second major food commodity with the highest imports bills. The implication on importation to meet the national fish need ranges from health to socioeconomic impacts. The lack of attention in the fisheries sector is costing Nigeria the economic benefits this sector provides.
القانون الجنائي والحاجة الى الفلسفة
Authors: عبد الله فراس عبد المنعم
Published: March 2022

هذهِ دراسة في استكشافية لأوجه الفائدة العملية التي يمكن للمنهج الفلسفي ان يقدمها في مجال القانون عموماً – والجنائي بشكل خاص.

لقد ساهمت الفلسفة بمدارسها المختلفة في تأصيل وتوجيه مسارات البحث في العلوم الأخرى الإنسانية والطبيعية، ولكننا نعتقد انها لم تقدم كل ما لديها في مجال القانون. وهو الأمر الذي يعود الى طبيعة القانون المعيارية، وصعوبة الفصل بين النسق القانوني والانسان والمؤسسات الاجتماعية والأخرى والتي ما زالت تؤثر سلباً في الكشف عن طبيعة القانون الحقيقية وتؤخر عملية اكتسابه لصفات العلم الحقيقي.

ولذلك فقد تم التركيز على اثبات قيمة الفلسفة العملية في تحديد طبيعة الظاهرة القانونية والفرز بينها وبين الظاهرة السياسية.

وصولاً الى تحليل الصلة بين العدالة الجنائية والقانون الجنائي ورد كلاهما الى الأصل المشترك وهو العدالة الاجتماعية.

ويتمثل الجانب التطبيقي للبحث في دراسة مفهوم العنف وتمييزه عن مفهوم القسر الجنائي واعتبار ذلك من أهم مظاهر ذاتية القانون الجنائي وفقاً للمقاربة الفلسفية.

Topical application revealed the high resistance of field populations of houseflies to pyrethroids (500–900?), neonicotinoids (345–500?), phenylpyrazoles (46–75?), susceptibility to FOS (0.6–1.4?) and oxadiazines (0.2?). With intestinal exposure, resistance rates are somewhat lower, but resistance remains at a high level to fipronil (33–76?), thiamethoxam (80–105?) and clothianidin (80–98?). Susceptibility to indoxacarb (0.2–1.4?) was revealed. The comparative efficacy of two modern baits based on indoxacarb and dinotefuran for resistant and susceptible strains of house flies was studied. Both insecticides are highly toxic to house flies in the form of commercially available baits. Indoxacarb and dinotefuran can be recommended for introduction into rotation schemes of insecticides in the form of food baits to control adult flies. Keywords: dinotefuran, indoxacarb, house flies, insecticide resistance, baits.
Sexo del primer hijo y resultados laborales de la madre: Evidencia para América Latina
Authors:   , Salas Peña Carlos
Published: March 2022

Esta investigación muestra que en algunos países de América Latina las mujeres cuyo primer hijo es un niño tienen menos probabilidades de trabajar que las mujeres con primogénitas. El objeto de estudio de esta investigación es tratar de entender por qué las mujeres reaccionan de esa manera. Para ello se puso a prueba la hipótesis del efecto de deseo por hijo niño (Dahl y Moretti, 2008) y del efecto divorcio (Bedard y Deschenes, 2005; Aninat y Michaels, 2008), a partir de una estrategia de identificación que considera que el sexo del primer hijo en la concepción es aleatorio. Utilizando datos censales en base al proyecto IPUMS se validó que los primogénitos inciden positivamente en la probabilidad de que un matrimonio sobreviva y ello se traduce en una caída en el empleo de las madres. Además, en el caso de Perú, Paraguay, Ecuador y Uruguay, se encontraron efectos positivos en la fecundidad cuando el primogénito es un niño, resultado que es consistente con lo encontrado en economías avanzadas. Mientras que en Argentina y México se observan efectos negativos en la fecundidad. Finalmente, se validan los resultados de Perú en base a la encuesta de hogares (ENAHO), encontrando además que tener un niño varón como primogénito presenta un mayor efecto negativo en los ingresos de las madres más pobres.

Published: March 2022

Powder metallurgy samples, made from Al7075 powder from ball milling, were produced and investigated. Samples were subjected to two different variables, those were compaction pressure and sintering temperatur. Compaction pressure variables were 250, 300, and 350 MPa with constant sintering temperatur of 505oC. Sintering temperatur variations were 425, 465, and 505oC with constant compaction pressure of 350 MPa. The results of density measurement and hardness test were directly proportional to both of research variables, whereas the porosity was inversely proportional. The properties of sample with variables of 350 MPa compaction pressure and 505oC sintering temperatur were the closest one to conventional Al7075, with density of 2.173 g/cm3, 22.2% porosity, and 12.56 VHN hardness. The properties of conventional Al7075 sample were 2.8 g/cm3 density, 0.26% porosity, and 12.68 VHN hardness.  The abrupt increase of hardness between 465oC and 505oC sintering temperatur was similar in pattern of its porosity decrease. This means optimum porosity decrease was started between 465oC and 505oC which affecting hardness increase. Highest hardness of powder metallurgy Al7075, which was 99% of conventional Al7075 and porosity of 22.2%, suggested wide application potential of Al7075 produced by powder metallurgy.

"The study has demonstrated that decaying seagrass accumulated along the shores is a particularly good source of cellulose and cellulose nanocrystals (CNCs). The FTIR spectra indicated the presence of O-H and C-H bonds in both the cellulose and CNCs obtained from the seagrass biomass. The Micro-Raman spectra showed maximum peaks at 1277 cm-1 for cellulose and at 1108 cm-1 for CNCs. The XRD spectra of cellulose confirmed its crystallinity, with a maximum peak for both cellulose and CNCs at 22°. The thermal stability of cellulose was lower than that of CNCs, where the latter showed thermal stability ranging between 110-250 °C. Overall, the cellulose and CNCs obtained showed good crystallinity and thermal stability. The particle size of the CNCs was recorded to be 253.2 nm. Also, they have a large surface area to volume ratio, which contributes to their high strength and stiffness. Thus, the cellulose and CNCs produced from decaying seagrass impart economic value to waste biomass, which can be a step towards the implementation of the wealth from the waste concept."

This study aimed at the recovery of cellulose from abundantly available wastes and its sustainable application. Firstly, in the cleaning process, cellulose-containing wastes, such as “air particle vacuum powder” (APVD), “towel clippings” (TC), and “cottonseed delintation residues” (CD), were thoroughly washed, separately, with tap water to remove some organic and inorganic impurities. The cotton slurry was purified by 17.5% NaOH at 90 oC for about 4 hours, then filtered and washed with tap water. Afterwards, the resulting pulp was bleached by NaOH and H2O2, and washed with distilled water until neutralized. Secondly, for the synthesis of carboxymethyl cellulose (CMC) from the above-dried celluloses, optimum conditions were achieved by varying the concentrations of components and ambient conditions. In the sample coded TCCMC3, a maximum degree substitution (DS) of 1.22, the highest consistency, the highest penetration time and the highest viscosity with 2520 centipoises (cP) were obtained from the reaction of towel clippings with 5.62 g sodium hydroxide and 13.12 g monochloroacetic acid (MCA) at 65 oC for 3 hours. Finally, the effect of these synthesized CMCs on the consistency and penetration time of a cement paste was investigated. The consistency of standard Portland cement (PC), without CMC addition, was 5 mm in the Vicat test, while the values measured for the cement pastes to which TCCMC3, APVDCMC3 and CDCMC3 were added reached 36.5 mm, 28.0 mm and 13.0 mm, respectively. While the setting time in the standard sample (Portland cement paste, PCP) was between 2.20-4.10 hours, this time shifted to 3.30-7.00 hours, with a maximum setting time recorded with the addition of TCCMC3. Besides, while the penetration time for APVDCMC3 started at 3.10 hours and was completed at 5.30 hours, for CDCMC3, it ranged between 2.40 and 4.40 hours, leaving it without hydration in a higher time interval than in the case of standard Portland cement paste. As a result, it has been found that carboxymethyl cellulose synthesized by the etherification reaction of cellulose obtained from recycled wastes for industrial uses, in an aqueous alkali environment, can be applied as a thickener in the construction industry and other fields.

Time-resolved photo-assisted Kelvin probe force microscopy on Cu(In,Ga)Se2 solar cells
Authors: Kuroiwa Tomoe , Takahashi Takuji
Published: March 2022

Photo-assisted Kelvin probe force microscopy (P-KFM) is very useful for examining photovoltaic characteristics especially on solar cells, although a time resolution in the conventional P-KFM was not sufficient for investigating carrier dynamics in time domain. In this study, we have introduced both an intermittent bias application method and a pump-probe method into P-KFM to realize time-resolved measurements at μsec order. Then the photo-carrier dynamics in Cu(In,Ga)Se2 solar cells with different Ga compositions have been examined by our time-resolved P-KFM through direct observation of rising and decay waveforms of the photovoltage induced by the pulsed light illumination and through two-dimensional observation of photovoltage distributions at various time intervals between the optical pump and electrical probe pulses.

Published: March 2022

Luminescence downshifting (LDS) effects of Zn-based Mn-doped nanoparticles (NPs) on characteristics of Si solar cells are investigated. ZnSe:Mn/ZnS core-doped core/shell NPs and ZnSe/ZnS:Mn/ZnS shell-doped core/shell/shell NPs are deposited on glass plates using layer-by-layer method. It is found that shell-doped NPs are superior as LDS materials by measuring their optical properties. We deposit LDS layers made of shell-doped NPs on Si cells and measure their internal quantum efficiencies (IQEs) to examine LDS effects separately from the effects of reflection on LDS layers. We find that IQEs for 300–400 nm are more enhanced for cells with thicker LDS layers. IQE at 350 nm is calculated for Si cells with LDS layers coated using an analytical model for the transmittance of downshifted photons into Si cells. IQEs for the respective cells are in qualitative agreement with the measurements.

This shipbuilding company is a pioneer company in Indonesia that produces various types of ships supported by technology from Australia (Computer Design Marine). Risky company activities can work fatigue, so companies need to pay attention to the health and safety of workers. In general, work fatigue is a condition that can occur in workers, where workers experience problems both physically and spiritually after work. Work fatigue is a factor that affects the work where fatigue can directly affect the performance of workers. The purpose of this research is to analyze the effect of characteristics and fatigue on the performance of workers. This study used an analytic research method with a p-type approach cross-sectional. Data was collected using interviews. Sampling is using the Simple Random Sampling method with 64 samples which are conducted to the workers in the shipbuilding production room. To determine the effect between two variables, this research used Chi-Square test analysis. The results showed that age (P=0.038), years of service (P=0.041), and fatigue (P=0.000) affected the performance of workers in the shipbuilding production room, while education level (P=1,000) didn’t affect labor performance in the shipbuilding production room.

Abstract Purpose: The main objective of this work is to evaluate the natural capital and ecosystem services of the Aquidauana River and the role of Lontra longicaudis and Pteronura brasiliensis as environmental assets for the development of conservation tourism. Research Methodology: First, a system diagram was built to organize ideas and relationships between components and resource flows. Second, it was to construct tables of emergy flows directly from the diagrams. Quantities of stored emergy of environmental resources are calculated from the sum of the emergy of all inputs and then multiplied by the time it takes to accumulate the storage. Results: The main services with market values ​​provided by the Aquidauana River are water supply, tourism, and fishing. The neotropical otter exhibited the largest asset in the system, followed by the giant otter and the indigenous culture. Limitations: Application of the emergy method to define public policies that lead to the real valuation of environmental assets and promote the social mobilization needed to change adverse realities. Contribution: The giant otter and neotropical otter values represent more than 90% of all values listed as environmental assets in the Aquidauana River System. The results can be important for the definition of public policies aimed at conservation tourism. With an appropriate social mobilization program, associated with economic and environmental education, the local economy could be strengthened, along with the protection of biodiversity.

SOCIOPRAGMATIC PRINCIPLES OF STUDENTS’ LINGUISTIC COMMUNICATION: CONCEPTS AND RULES
Authors: Gozieva Mastona
Published: March 2022

The purpose of this article is to study the socio-pragmatic principles of linguistic communication of students. In recent years, as a result of developments in various spheres of society, the demand for foreign languages is growing. In today's era of globalization, we all know that the main demand of the labor market in the advanced countries of the world is the ability to communicate in a foreign language, knowledge of computer technology and rich innovative ideas and their own style. Measures to further improve the system of study of foreign languages were highlighted in the Law on Education, the National Program of Personnel Training and the Law on Education adopted by the Oliy Majlis of the Republic of Uzbekistan.
The main purpose of teaching a foreign language at all levels of education in the Republic of Uzbekistan is to enable students to work abroad in scientific and industrial fields in a multicultural world formation of communicative competence in the language.
The concept of competence varies in many foreign and domestic publications by representatives of different fields depending on their activity.
However, the basis of this term is considered to be a single content, that is, the integration of concepts such as knowledge, skills and abilities in a person and the ability to apply them correctly in different situations. It follows that the communicative competence in a foreign language is the ability to apply existing knowledge, skills and competencies in a foreign language in the process of communication. The state educational standard of the Republic of Uzbekistan includes linguistic, sociolinguistic, pragmatic competencies as components of communicative competence in a foreign language, which serve as the basis for its improving. It is true that any language is a means of communication for people. As long as a person lives in a certain society, he/she must interact with others, have the same language, beliefs and share social events. It should be noted that mastering only the linguistic features of a foreign language studied during the acquisition of a foreign language does not provide real written and oral communication. The cultural values of the language studied in the article are also socio-pragmatic principles, rules concepts are analyzed.
City Minimum Wages and Spatial Equilibrium Effects
Authors: Pérez Pérez Jorge
Published: March 2022

Este documento estudia el efecto de cambios al salario mínimo en los equilibrios espaciales de mercados laborales locales. Usando datos de EUA y variación en salarios mínimos entre límites estatales, analizo cómo los viajes a trabajar y los lugares de residencia y trabajo cambian en respuesta a cambios locales en el salario mínimo. Encuentro que las áreas donde el salario mínimo aumenta reciben menos viajes de trabajadores de bajo salario. Formulo un modelo de equilibrio espacial y calculo contrafactuales con salarios mínimos más altos para las ciudades de EUA que están considerando incrementos. Para cambios pequeños en el salario mínimo, la mayoría de los condados recibirían más viajes a trabajar y tendrían menos residentes de bajo salario. A medida que los incrementos al salario mínimo son mayores, hay mayores reducciones en viajes de trabajadores de bajo salario debido a reubicación del empleo.

Published: March 2022

In this paper, we propose a
novel neural network for Compressed Sensing (CS) application: the Dictionary
Learning based Compressed Sensing neural Network (DL-CSNet). It is fairly
simple but highly effective, which consists of only three layers: 1) a DL layer
for latent sparse features extraction; 2) a smoothing layer via Total Variation
(TV) like constraint; and 3) a CS acquisition layer for neural network
training. In particular, the TV-like smoothing layer is a perfect complement to
the sparsity-oriented DL layer to achieve smooth images. The trained DL-CSNet
can learn the optimal dictionary matrix so that images can be reconstructed in
high quality. At last, extensive experiments have been carried out on binary
images and compared to most classical CS algorithms, which shows the superior
performance of the proposed DL-CSNet.
