Heat generation based on wood fuel as a basis for improving energy effi ciency in the timber industry
Теплогенерация на основе древесного топлива повышает энергоэффективность в лесопромышленном производстве. Древесное топливо является возобновимым и экологичным ресурсом и рассматривается как эффективная замена топливу из ископаемых ресурсов. Применение нормированных видов древесного топлива позволяет снизить затраты на теплогенерацию. Древесное топливо имеет самые низкие показатели выделения углекислого газа, а также отсутствие серы при сгорании, что обеспечивает экологичность применения данного вида топлива. Важными организационными мероприятиями по переходу на древесные виды топлива являются создание унифицированных муниципальных топливно-технологических терминалов, расширение производства топливной щепы при рубках ухода, а также экспорт избыточной топливной щепы. Эти мероприятия позволяют увеличить количество высокопроизводительных рабочих мест.Heat generation based on wood fuel increases energy effi ciency in the timber industry. Wood fuel is a renewable and environmentally friendly resource and is seen as an effective substitute for fossil fuels. The use of standardized types of wood fuel can reduce the cost of heat generation. Wood fuel has the lowest rates of carbon dioxide emissions, as well as the absence of sulfur during combustion, which ensures environmental friendliness of this type of fuel. Important organizational measures for the transition to wood fuels are the creation of unifi ed municipal fuel technology terminals, the expansion of the production of fuel chips during logging operations, as well as the export of excess fuel chips. These activities increase the number of high-performance jobs

DYNAMICS OF CHANGES OF LIVE WEIGHT AND HEMATOLOGIC INDICATORS OF COW CALVES OF SIMMENTALSKY BREED TO 6 MONTHLY AGE DEPENDING ON THE TECHNOLOGICAL SCHEME OF FEEDING
Завдяки розробленій схемі годівлі теличок від народження до 6-місячного віку у виробничих умовах на поголів’ї чистокровних телиць симентальської породи, отримано живу масу тварин у віці 6 місяців, яка в середньому перевищує вимоги стандарту породи.В ході емпіричних досліджень було досягнуто скорочення витрат незбираного молока шляхом використання престартерного комбікорму «Малюк-60», цільного зерна кукурудзи, соєвого замінника молока, стартерного комбікорму власного виробництва, лучного сіна і сінажу злаково-бобового. В процесі експерименту була вирішена проблема часткової заміни в схемі годівлі телят молочного білка, шляхом комплексної заміни білка знежиреного молока на білок сої в складі рідкого соєвого замінника, гранульованого престартерного комбікорму «Малюк-60» і стартерного комбікорму власного виготовлення. Гематологічними спостереженнями встановлено, що об’єктивні морфологічні та біохімічні показники крові не виявили достовірних суттєвих відмінностей між тваринами обох груп і відхилень від фізіологічних норм. Спостерігалась незначна тенденція до збільшення концентрації цукру в крові телиць контрольної групи. Це пояснюється тим, що тварини даної групи споживали незбираного молока більше, ніж дослідні тварини.Грошові витрати кормів на одержання 1 кг приросту живої маси, на час проведення дослідів становили 3,29 грн у дослідній групі проти 3,76 грн у контролі.Благодаря разработанной схеме кормления телок от рождения до 6-месячного возраста, в производственных условиях, на поголовье чистокровных телок симментальской породы, живая масса животных в возрасте 6 месяцев в среднем по группе превышала требования стандарта породы.В ходе эмпирических исследований было достигнуто сокращение расходов цельного молока путем использования престартерного комбикорма «Малыш-60», цельного зерна кукурузы, соевого заменителя молока, стартерного комбикорма собственного производства, лугового сена и сенажа злаково-бобового. В процессе эксперимента была решена проблема частичной замены в схеме кормления телят молочного белка, путем комплексной замены белка обезжиренного молока на белок сои в составе жидкого соевого заменителя, гранулированного престартерного комбикорма «Малыш-60» и стартерного комбикорма собственного изготовления. Гематологическими наблюдениями установлено, что объективные морфологические и биохимические показатели крови не обнаружили достоверных существенных различий между животными обеих групп и отклонений от физиологических норм. Наблюдалась незначительная тенденция к увеличению концентрации сахара в крови телок контрольной группы. Это объясняется тем, что животные данной группы потребляли цельного молока больше, чем в опытной группе.Денежные затраты кормов на получение 1 кг прироста живой массы, на время проведения опытов составляли 3,29 грн в опытной группе против 3,76 грн в контроле.The most recently modernized farms and complexes show results I will milk on a cow at the level of 5000–6000 kg of milk and anymore high-performance his quality. In connection with translation of the cattle breeding on industrial basis and organization of farms there was a necessity to work out the fundamentally new going near the system of growing repair to the sapling/pl in the specialized economies. Thus salubrity and high manufacturability of animals must be assured with a high enough yield. The further height of the suckling and meat productivity must provide the not height of population, and increase of his productivity.Thesis is devoted to usage issues of well-balanced mixed fodders concentrates in calves rations. They are able to provide high enough level of daily increase of animals live weight. The scheme of calves feeding since their birth till the age of 6 months has been developed in the process of research. The usage of this scheme for one heifer head rising allows to spend only 180 kg of beestings and whole milk, to receive high enough level of average daily increase of animals live weight, to provide animal mass in the age of 6 months at the level of 175 kg (that is in conformity with standard requirements for 6 months young animals of symmental stock).Materials testify to absence of substantial difference in intensity of height of animals of both groups, expenses of energy, dry substance, raw and digestible protein. Expenses of forage units, exchange energy, dry substance, raw and digestible protein, and also costs of forage on 1 kg of increase of living mass experience animals have less than, than in control, that testifies in behalf on the worked out new chart of feeding of heifers of age to 6-monthly age.Hematologic observations established that the objective morphological and biochemical indices of blood found no significant differences between animals significant in both groups, and the deviations from the physiological norm. There was a slight tendency to increase the concentration of sugar in the blood heifers in the control group. This is due to the fact that the animals in this group of whole milk consumed is greater than in the experimental group.Cash costs of feed to produce 1 kg of live weight gain, at the time of the experiments were 3.29 USD. in the experimental group versus 3.76 USD. in the control

Comparative characteristics of tuberculous pleurisy depending on HIV status
Goal of the study: to study specific manifestations of tuberculous pleurisy in HIV patients, to evaluate the efficiency of video-assisted thoracoscopy when diagnosing tuberculous pleurisy in case of different HIV status of the patients.Materials and methods: 241 tuberculous pleurisy patients were examined. 88 – HIV positive (group 1), 153 – HIV negative (group 2). Average CD4 count in group 1 made 189 cells/mcl. The following parameters were compared in those groups: clinical and X-ray manifestations, microbiological, cytologic and biochemical rates in blood and effluent. 77 patients with isolated pleurisy (of them 33 HIV positive) had video-assisted thoracoscopy with biopsy for diagnostic purposes. The data of histological examination of pleura, obtained through video-assisted thoracoscopy and autopsy have been presented.Results: tuberculous pleurisy with concurrent HIV infection is characterized by frequent occurrence of hemorrhagic effusion, scarce cellular sediment of effluent, expressed reduction of glucose level and increase of thymol test rates in effluent. Regardless of HIV status the frequency of tuberculous mycobacteria detection through microscopy and culture is low and does not exceed 10%. Histological testing of specimens obtained through video-assisted thoracoscopy allowed proving tuberculosis in all patients thus differentiating tuberculous changes from metastases. Thus video-assisted thoracoscopy can be recommended for diagnostics of difficult cases of tuberculous pleurisy regardless of HIV status.From morphological point of view tuberculous pleurisy was characterized by specific granulomas which were presented by lymphoid and epithelioid cells with Pirogov-Langhans cells with minor caseous necrosis in the center (9.1%) or its complete absence (90.9%)
Formation of Multicultural Competence of Future Tourist Support Specialists (Guides) as a Pedagogical Problem
The purpose of the paper is to study multicultural competency training future tourist support specialists (guides) in the higher educational institutions. Multicultural competency training is defined as ways of teaching and educating aimed at developing multicultural competency. It may include: creating awareness of one’s cultural worldview, stereotypes and biases; deepening knowledge of different cultural practices and views; understanding and understanding that cultural and linguistic differences can affect communication; understanding why and how communication and behaviour should be adapted in different cross-cultural situations; how to work effectively and respectfully with people of different cultural and linguistic backgrounds; highlighting the benefits of diversity in the workplace or in society more broadly; creating plans and strategiesfor developing organisational multicultural competency, such as multicultural access and equity or hiring policy plans. At the university organisational level, developing multicultural competency requires clear and practical policies and procedures, as well as a commitment to implementation and evaluation to create a workplace that evaluates and matches cultural and linguistic diversity
