The subject of this research is the specifics, forms and functions of interaction in social media groups between the representatives of ethnic communities. The goal consists in determination of the role of social networks in adaptation of ethnocultural communities of St. Petersburg. The research is based on the polling technique for acquisition of information on the cognitive, emotional, and behavioral state of a person. The survey was conducted via distribution of questionnaires among the representatives of ethnic groups. The article also employs the method of systematic scientific observation over the social media groups, topic raised therein, as well as reading and analysis of the comments. The scientific novelty of this work consists in outlining of the nature, trends and development prospects of cross-cultural communications as the channel for ethnocultural interaction.  The main conclusions, which touch upon users from various ethnic communities who do not have enough experience in organization of activity of social media groups, demonstrate that it causes the loss of the sense of security, accumulation of prejudices and escalation of interethnic conflicts, as well as preference of the with restricted access, which contributes to lock down of the group and impedes adaptation in the accepting society. Stabilization of situation can be achieved by improvement of the quality of content posted in the social media, as well as level of their administration.

One of the efforts to achieve national food security is by strengthening assistance and counseling to farmers as the main actors. One of the extension links closest to the community and located at the sub-district level is the Peratanian Extension Center (BPP). The function and role of BPP is developed to achieve the desired expectations, namely food self-sufficiency and improvement of farmer welfare. Therefore, there is a need for a special study to be able to determine the level of responsiveness, responsibility and quality of agricultural extension services carried out by the BPP in Sidenreng Rappang Regency. This reserch aims to determine the performance of agricultural extension agents in Sidenreng Rappang Regency in terms of the level of accountability of agricultural extension activities based on indicators of responsiveness, responsibility and quality of extension services. The research was conducted from July to October in Sidenreng Rappang Regency. This research used a survey method. Determination of the sample of this study was carried out purposively on extension workers at the local BPP. Data collected descriptively by cross tabulation. Data analysis used scoring parameters, proportion, maximum, minimum and average values. The results show that the agricultural instructor's Performance Score is 294 which is interpreted into a moderate category score, which means that the ability of the BPP is sufficient to be able to recognize the needs of the assisted farmers, is sufficient to develop extension programs / activities that are in accordance with the wishes / aspirations of local farmers, and sufficient in providing service to farmers.

With the rapid economic development, water pollution has become a major concern in China. Understanding the spatial variation of urban wastewater discharge and measuring the efficiency of wastewater treatment plants are prerequisites for rationally designing schemes and infrastructures to control water pollution. Based on the input and output urban wastewater treatment data of the 31 provinces of mainland China for the period 2011–2015, the spatial variation of urban water pollution and the efficiency of wastewater treatment plants were measured and mapped. The exploratory spatial data analysis (ESDA) model and super-efficiency data envelopment analysis (DEA) combined Malmquist index were used to achieve this goal. The following insight was obtained from the results. (1) The intensity of urban wastewater discharge increased, and the urban wastewater discharge showed a spatial agglomeration trend for the period 2011 to 2015. (2) The average inefficiency of wastewater treatment plants (WWTPs) for the study period was 39.2%. The plants’ efficiencies worsened from the eastern to western parts of the country. (3) The main reasons for the low efficiency were the lack of technological upgrade and scale-up. The technological upgrade rate was −4.8%, while the scale efficiency increases as a result of scaling up was −0.2%. Therefore, to improve the wastewater treatment efficiency of the country, the provinces should work together to increase capital investment and technological advancement.

Final Confirmation

It is well known that the value of full feeding of farm animals is an important condition for the production of livestock products. Because of the researches of many scientists was found that the value of feed is determined by the content of proteins, fats, carbohydrates, as well as vitamins, minerals and so on. However, the true value of the feed is determined by the part that is digestible and can be used by the body in the metabolism process. In the event of a violation of feeding level associated with the lack of nutrients or minerals of animals or their deficiency, the development of osteodystrophic processes is observed, which directly contribute to changes in the tendon-ligamentous apparatus of the finger of animals, there is an occurrence of prolonged osteotendinitis of the finger flexors, which causes to fingers extension, partially or completely removed from the hoof wall support, and overload of crumbs. Tightening of the crumb support is accompanied by the appearance of the skin of the hoof inflammatory process, excessive horn growth and deformation of the horn capsule. The final confirmation of osteodystrophy is the results of a multivariate mass volumetric analysis of the skeleton state and determination of the magnitude of the angles of the joints of the fingers. On the side of the hoof horn, there is an increase in the moisture content and SH-groups and a decrease in g-keratosis, which affects the biophysical properties of the hoof horn, which are shown by a decrease in density and hardness. Such changes indicate a deterioration in the quality of the hoof horn, a confirmation of which is a decrease in the intensity of erasing of the sole horn, the development of deformation and the occurrence of aseptic inflammation of the base of the skin of the sole horn.

Upstream Process

Using cross flow microfiltration as a tertiary treatment would make the treatment reliable and achieve virtually a total disinfection. However, the use of the membrane techniques is IimiIed because of the material fouling. Our results show that the fouling mechanisms depend on the choice of the secondary upstream process. The quality of the effluent and the permeaIe flux obtained are very different if the sewage has been treated by a biological or by a physico-chemical process. The operating conditions of these processes have also an influence on the variations of the membrane permeability. In particular we have observed the importance of the load in the case of an activated sludge process and the role of the coagulant dose in the case of a physico-chemical process. The supracolloidal fraction of the suspensions seems to be one of the main fouling reasons.

Broodstock Nutrition

Many of the hypotheses and proposals presented here on the role of nutrition in lobster recruitment have been derived from research on other aquatic animals. Little research has focused on the determination of nutritional requirements of lobsters and even that has been primarily with small juveniles (36–1000 mg). Despite the tacit acknowledgement that maternal fecundity and egg viability are a function of quantity and quality of available food, little is known about the nutrition of reproductively mature lobsters. The importance of broodstock nutrition and possible methods for evaluating nutritional status are discussed. Information on protein, essential amino acids, vitamins, minerals, carbohydrates, and lipids is summarized. Additionally, some proposals for field application of nutritional response criteria used in the laboratory are discussed. Though research on larvae adult broodstock nutrition, effects of environmental factors (e.g. temperature, salinity, photoperiod, etc.), as well as many other aspects of nutrition is yet to be done, there is "good opportunity" for nutrition to be a significant part of the current lobster recruitment research program.

A system involving enumeration of Escherichia coli I, parasite units, staphylococci and salmonellas, and determination of salinity, was developed for the objective assessment of bacterial water quality in the sea off Durban, South Africa. The system was used to measure the quality of the surf waters before and after the construction of two submarine outfalls. Significant improvement in the quality of the surf along the bathing beaches has been noted since the outfalls became operational.
