Shifting Boundaries

From time immemorial people began to domesticate wild animals and throughout many generations, they are kept by people genetically isolated from external pathogens. In the prevailing era, every pet owner is trying to breed and protect his animal from contagious and noncontagious diseases. Having said that, lack and inadequacy of knowledge and mass media on simple preventive measures results in the widespread occurrence of infectious and invasive diseases, including flea, Ctenocephalides felis infestation among dogs as well as cats. The present paper primarily attempts to present the results of therapeutic efficiency of Komfortis, Foresto, and Fitoelita medical agents used during flea infestation among domestic cats. In order to meet the purpose of the study, research was carried out within the framework of study and analysis of the epizootic state of invasive diseases of agricultural and unproductive animals, bees, and birds. Studies of changes in the species composition, and bioecological patterns of the development cycle of parasites under shifting boundaries of their ranges were also done. For the study, the animals were divided into three groups of 10 animals each. Standard clinical and hematological research methods were used during the study. Blood sampling included three stages: before insecticide treatment, the intermediate interval of 15 days, and the final stage. Based on the results obtained, it was found that Komfortis and Foresto have 100% therapeutic efficacy at all stages of flea development and possess a long-lasting action duringa flea infestation. The morphological blood analysisshowed that the proposed medical agents have no toxic orsideeffects.

Favorable Conditions

Modern fish farming having intensive forms of farming provides for feeding fish with artificial feed, fertilizing ponds and compacting fish planting in nursery, finishing and wintering ponds. This leads to close contact of cultivated fish and, in this regard, favorable conditions for the pathogens accumulation in ponds, the distribution of infectious and invasive diseases. Invasive diseases are a significant danger among diseases including pond fish dactylogyrosis. Dactylogyrosis are monogenetic suckers, parasites with a direct development cycle, live on the fish gill filaments, belong to conditionally pathogenic parasites and pose a serious danger to young fish. Despite a fairly complete study of the biology of carp dactylogyrid, a number of questions regarding the formation of the parasitofauna of these young fish in the early stages of development - the most vulnerable period of their lives - remain little covered in the literature. The work presents data on the Dactylogyrus types found in young carp in the nursery ponds of the Orenburg region, the invasion extensiveness and intensity. 4 species of monogenetic suckers have been found: Dactylogyrus vastator, Dactylogyrus extensus, Dactylogyrus achmerowi, Dactylogyrus anchoratus. Among the four species of Dactylogyrosis, only two species, Dactylogyrus vastator and Dactylogyrus extensus, were found most often and from an early age, two other species were found in older fish, 20 and 25 days of age with little invasion extensiveness and intensity.

Usual Development

Internet of Things (IoT) learning involves the acquisition of transversal skills ranging from the development based on IoT devices and sensors (edge computing) to the connection of the devices themselves to management environments that allow the storage and processing (cloud computing) of data generated by sensors. The usual development cycle for IoT applications consists of the following three stages: stage 1 corresponds to the description of the devices and basic interaction with sensors. In stage 2, data acquired by the devices/sensors are employed by communication models from the origin edge to the management middleware in the cloud. Finally, stage 3 focuses on processing and presentation models. These models present the most relevant indicators for IoT devices and sensors. Students must acquire all the necessary skills and abilities to understand and develop these types of applications, so lecturers need an infrastructure to enable the learning of development of full IoT applications. A Web of Things (WoT) platform named Labs of Things at UNED (LoT@UNED) has been used for this goal. This paper shows the fundamentals and features of this infrastructure, and how the different phases of the full development cycle of solutions in IoT environments are implemented using LoT@UNED. The proposed system has been tested in several computer science subjects. Students can perform remote experimentation with a collaborative WoT learning environment in the cloud, including the possibility to analyze the generated data by IoT sensors.

The ectoparasites Ctenocephalides felis and Ctenocephalides canis are distributed worldwide and are the most common species of fleas that parasitize domestic carnivores. As active vectors of infectious and invasive diseases, fleas of the genus Ctenocephalides are of great epidemiological importance. Intensive growth of the number of dogs, violation of sanitary and hygienic conditions of their keeping, especially in large cities, as well as global warming significantly affect the epizootic situation regarding ctenocephalidosis. The aim of the work was to study the features of age susceptibility of domestic dogs in the city of Poltava (Ukraine) to Ctenocephalides spp. Indicators of infestation of animals with the causative agent of ctenocephalidosis depending on their age and housing conditions were determined. Studies have shown that dogs of any age are prone to flea infestation. Ctenocephalidosis is diagnosed in animals of all ages. At the same time, the age dynamics of defeat of dogs by parasitic insects under different conditions of their keeping differed significantly. The average extensity and intensity of the invasion was lower in animals kept in apartments (26.47 %, 10.82 specimens/head) compared to animals kept in the private sector (76.21 %, 22.71 specimens/head). The highest rates of flea infestation of the genus Ctenocephalides were found in dogs aged one to six years (37.10–45.45 %; 10.45–15.91 specimens/head) – for housing, as well as in young animals up to 12 month of age (84.03–90.36 %; 22.78–32.56 specimens/head) – for aviary maintenance. Less infested were dogs under 6 months of age (11.26 %; 5.43 specimens/head) and older 6-year-olds (16.28 %; 8.54 specimens/head) – for housing, as well as dogs aged one to six years (53.54–75.38 %; 11.63–20.24 specimens/head) – for aviary keeping. The results obtained regarding the age dynamics of infestation of domestic dogs with fleas of the genus Ctenocephalides can be taken into account when carrying out measures to control and prevent ctenocephalidosis in dogs under different conditions of their content.

Differences exist in the pace of regional development in China between the richer Eastern coastal and poorer Western regions. These differences may result from the relative success of national and regional policy initiatives or more simply the ability of businesses to access finance. High-tech businesses are being encouraged by China's government as a means of rebalancing regional development from the existing physical resource-intensive industries. In this paper we examine the experiences of high-tech small and medium-sized enterprises (SMEs) in relation to securing finance, evaluating the experiences at the three stages in their development. The empirical evidence, based on seventy-four face-to-face interviews with owners and senior managers of high-tech SMEs and on nine with bank and government officials, facilitates a comparison of the two study regions, Guangdong and Guangxi provinces. The findings indicate significant differences in the availability and nature of financial sources between the two regions. Firms in the more-developed Eastern region experience access to a wider range of funds from both formal and informal sources than their counterparts in the less-developed Western region. Although this was evident at all three stages of the business development cycle, it was more significant during the earlier stages of development. The consequences of such a disparity in financial sources may lead to further exacerbation of the regional differences and hence prove counterproductive in seeking to develop a more balanced strategy of economic development. We conclude by discussing the prospects for improving this present situation through policy initiatives.

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.
