Avian Reproduction

There are about 10,400 living avian species belonging to the class Aves, characterized by feathers which no other animal classes possess and are warm-blooded vertebrates with four-chamber heart. They have excellent vision, and their forelimbs are modified into wings for flight or swimming, though not all can fly or swim. They lay hard-shelled eggs which are a secretory product of the reproductive system that vary greatly in colour, shape and size, and the bigger the bird, the bigger the egg. Since domestication, avian species have been basically reared for eggs, meat, pleasure and research. They reproduce sexually with the spermatozoa being homogametic and carry Z-bearing chromosomes, and the blastodisk carries either Z-bearing or W-bearing chromosomes, hence, the female is heterogametic, and thus, determines the sex of the offspring. The paired testes produce spermatozoa, sex hormones and the single ovary (with a few exceptions) produces yolk bearing the blastodisk and sex hormones. Both testis and ovary are the primary sex organs involved in sexual characteristics development in avian. In avian reproduction, there must be mating for fertile egg that must be incubated to produce the young ones. At hatch, hatchling sex is identified and reared to meet the aim of the farmer.

Analysis of application development needs and discussion on the platform architecture of the Internet of Things

To improve the development efficiency of Internet of Things applications and meet the needs of innovative projects. In this paper, two methods are used to analyze the application development requirements of the Internet of Things, namely, modularization analysis and development characteristics analysis. In modular analysis, development objectives are divided into a series of modules with strong robustness based on the functional requirements in the project. In the analysis of development characteristics, development suggestions are put forward according to the difference of development characteristics between the node side and server-side of the Internet of Things. After the analysis, specific suggestions for the application development of the Internet of Things are put forward, including the simple selection of the hardware of the Internet of Things node, an architecture scheme of the Internet of Things platform, and the application scenarios are discussed.

Sollutions of creation and development issues of industrial parks in Azerbaijan

Growing economic development requires a transition to more environmentally friendly production systems. Industrial parks provide more environmentally friendly and efficient production systems. In Azerbaijan, which has long been the main focus of the extractive industry and the chemical industry, a new industrial policy is being formed in the context of changing economic conditions. There is a great potential for the formation of industrial parks in Azerbaijan. In this study, we provided information on the characteristics, development and operation of industrial parks. At the same time, we tried to explore opportunities for the formation of industrial parks and future eco-parks in Azerbaijan. Key words: efficiency, industrial parks, emissions, financial experts, commitment targets, profitability

The application of computer graphics processing in visual communication design

The purpose of this paper is to improve the existing computer graphics image processing technology, so that designers can produce more inspiration, improve the author’s ability to innovate. Based on the information in the field of graphics visual communication as the research object, through the elaboration of graphical information characteristics, development course, and the visual communication of computer graphical related, such as cognitive psychology, semiology theory research, analyzes the computer graphics into a kind of economic and effective way of conveying information, the significance of interface design for mobile media. Experiments demonstrate the unique advantages of graphics in the process of information transmission. In 2022, the market size of computer graphics and vision will expand to 755.5 million RMB. It can be known that the communication mode integrating information and graphics, as the future development trend, will also be applied to more fields and play a greater role.

Analytical Comparative Study of Some Kinematic Variables Affecting the Distances of 200 m. Freestyle Race

The study aimed at identifying some kinematic variables affecting the distances of 200m freestyle race among the swimmers of the Specialized School for Swimming. Three (3) swimmers have been intentionally chosen to be the subjects of the study. The kinematic variables of each player have been extracted by the motor analysis (kinovea) program and their data values then compared. In light of the results, the researcher found out clear big differences in the values of these variables among the swimmers themselves and between each distance of the race distances for each swimmer which led to a big variation in the achievement (final time). A matter that requires reforming procedures in the technical performance and physical characteristics development for the swimmers of the Specialized School in 200m freestyle event in order to reduce the final time (improving achievement).

Estudo paleográfico de cartas manuscritas do final do século XIX no Amazonas / Paleographic Study of Handwritten Letters from the Late 19th Century in the Amazon

Resumo: Apoiado nos pressupostos teórico-metodológicos de Cambraia (2005), Costa (2006), Flexor (1990), Núñez Contreras (1994) e Riesco Terrero (1999), propõe-se um estudo paleográfico de três cartas manuscritas do ano de 1890, referentes a assuntos comerciais da empresa J. G. Araújo e Cia Ltda, as quais se encontram sob a guarda do Museu Amazônico na cidade de Manaus (AM), Brasil. No presente estudo paleográfico, trata-se de aspectos materiais, de elementos constitutivos da escrita, de características ortográficas, de desenvolvimento e tipologia de abreviaturas, de edições de cartas e, por fim, traça-se um paralelo entre especificidades gráficas das três cartas com outras três, também relativas ao final do século XIX, porém de outra região do Brasil.Palavras-chave: cartas manuscritas; crítica textual; estado do Amazonas; paleografia.Abstract: Supported by the theoretical-methodological assumptions of Cambraia (2005), Costa (2006), Flexor (1990), Núñez Contreras (1994) and Riesco Terrero (1999), we propose a paleographic study of three unpublished handwritten letters of 1890, referring to commercial affairs of the company J. G. Araújo e Cia Ltda, which are under the custody of the Amazonian Museum in the city of Manaus (AM), Brazil. The present study deals with material aspects, constitutive elements of writing, orthographic characteristics, development and typology of abbreviations, letter editions and, finally, a parallel is drawn between the graphic specificities of the three letters with three others letters, also related to the end of the nineteenth century, but from another region in Brazil.Keywords: handwritten letters; textual criticism; state of Amazonas; paleography.

Influence of Leadership on Organizational Effectiveness of Commercial Banks And Political Parties

Kosovar society needs a leadership that has and brings new ideas in all spheres, starting from the family to the central level of the state. An important factor in the development of political parties and their activities is undoubtedly the development of a successful leadership, in order to achieve the objectives that contribute to improving the well-being of the population and the economic development of the country. The main purpose of this paper is to study the effectiveness of leadership in banking organizations in Kosovo and the study of leadership in organizations of political parties in Kosovo. Decision-making analysis, leader characteristics, development of communication with subordinates, way of clarifying the objectives of the organization, etc. will be discussed in this paper. During 2018, the loan portfolio of banks operating in Kosovo was about 2.76 billion euros. Sassipre / econometric analysis was also used in this research. Leaders of political parties in terms of decision-making turn out to be more focused on the program of political parties with about 52.1%. The linear correlation of the determination correlation is positive.471. , etc.
