The exterior is closely related to the constitutional characteristics of animals. In the conditions of the steppe zone of Ukraine, as in other regions, research is not enough and this work should be continued, since evolutionary changes in the rocks occur constantly. Therefore, our research is relevant. In the experimental farm of the Institute of Grain Crops, 3 groups of bull-calves of specialized meat Hereford, Charolese and combined Simmental breeds were formed (15 animals each). The content was loose, the feeding conditions were the same. Herefords are smaller than Charolais and are inferior to them in all body measurements (height, width, length, depth). However, they are more compact with pronounced meat forms. Although after 18 months of age, the indicators of articles decreased markedly and some obesity was observed, which confirms their early maturity. Gobies were characterized by a harmonious physique, had rounded shapes, and their lateral profile resembled a rectangle, which indicates a potentially high meat productivity. Their head is short and wide, the neck is short and thick, the chest is deep, wide with rounded ribs, but relatively short, the topline is straight and wide, the back is straight, long, wide, the legs are widely spaced, strong, the muscles are magnificently developed, the skin is loose, thick long hair. At the end of the study, the exterior features of Simmental bulls differed in a greater direction from animals of specialized meat breeds in terms of measurements of such items as height at the withers, back and rump, depth and chest girth. However, they were inferior to them in chest width, in the hips, hip joints, sciatic tubercles.
外观与动物的体质特征密切相关。与其他地区一样,在乌克兰草原地区的条件下,研究是不够的,这项工作应该继续下去,因为岩石的演化变化是不断发生的。因此,我们的研究是相关的。在粮食作物研究所的实验农场,形成了赫里福德、查洛泽和西门塔尔组合品种的3组公牛犊牛(每组15头)。内容物疏松,饲喂条件相同。赫里福德比夏洛莱小,在所有身体测量(高、宽、长、深)上都不如夏洛莱。然而,它们更紧凑,有明显的肉状。虽然在18月龄后,动物各项指标明显下降,并出现部分肥胖现象,证实了它们的早熟。虾虎鱼的特点是和谐的体格,圆润的外形,侧面轮廓类似矩形,这表明它们潜在的高肉类产量。他们的头短而宽,脖子短而粗,胸部深,宽,肋骨圆形,但相对较短,背线直而宽,背部直,长,宽,腿间距宽,强壮,肌肉华丽发达,皮肤松弛,浓密的长毛。在研究结束时,西门塔尔公牛的外部特征与专门肉类品种的动物在诸如肩隆高度,背部和臀部,深度和胸围等项目的测量方面有很大的不同。然而,他们在胸宽,臀部,髋关节,坐骨结节方面都不如他们。

An increase in beet production at the present stage is possible only with the use of intensive technologies, where the integrated protection of crops from harmful organisms is of great social and economic importance. In the system of measures aimed at increasing the production of beetroots, an important place is the protection of sugar beets from diseases. Successful control of sugar beet diseases is an important reserve for increasing the yield and sugar content of root crops and improving their technological quality. A rather dangerous disease of sugar beet is the root eater, which is widespread throughout Ukraine, especially in the zone of sufficient moisture. Conducting studies to study the effect of certain agro technical measures, as more economically affordable, on the formation of harmful microorganisms that contribute to the development of root and other root diseases during the growing season, the effect of sugar beet concentration in crop rotation. In the experiments, various types of crop rotation were studied: grain-sowing, grain-cultivating (with green manure) and fruit-bearing. The technology for growing crops is generally accepted. Pesticides were not used in the experiments, with the exception of seed dressing. Studies have established that the main causative agent of the root in the conditions of the western forest-steppe of Ukraine are various species of fungi of the genus Fusarium i Aphanomyces cochliondes. The dominance of these pathogens among pathogens causes the most severe defeat of beets in the phase of the first pair of leaflets, as well as the death of plant diseases in a later period - after the formation of planting density. Studies have shown that the lowest prevalence of sugar beet diseases was observed at a saturation level of 17% when they were grown in one place after 5 years (the average degree of development of the root was 14.7%). The development of the disease increased with a decrease in the time of returning to the previous place of cultivation in the rotation. So, on average, over a three-year period, the reduction of this period to four to two years increased the degree of root beetle damage to 15.4-19.8%. At a one-year break and re-sowing, this indicator was 24.4% and 27.2%, respectively. Based on the results obtained, it can be argued that an increase in the concentration of sugar beets in the crop rotation leads to an increase in the distribution of the root.
现阶段,只有采用集约化技术才能增加甜菜产量,在集约化技术中,综合保护作物免受有害生物侵害具有重大的社会和经济意义。在旨在增加甜菜根产量的措施体系中,保护甜菜免受病害是一个重要的地方。甜菜病害的有效防治是提高根茎作物产量和含糖量,提高技术品质的重要保障。甜菜的一种相当危险的疾病是食根病,在乌克兰各地普遍存在,特别是在水分充足的地区。开展研究,研究某些经济上负担得起的农业技术措施对有害微生物形成的影响,这些有害微生物在生长季节导致根系和其他根系疾病的发展,以及作物轮作中甜菜浓度的影响。在试验中,研究了不同作物轮作方式:播种、绿肥栽培和结果。种植农作物的技术已被普遍接受。除种子处理剂外,试验中未使用农药。研究已经确定,在乌克兰西部森林草原的条件下,根的主要病原体是镰刀菌属的各种真菌。这些病原菌在病原菌中的优势地位导致甜菜在第一对小叶阶段遭受最严重的失败,以及后期——在种植密度形成之后——植物病害的死亡。研究表明,当甜菜在一个地方生长5年后达到17%的饱和水平时,甜菜病害的发病率最低(根的平均发育程度为14.7%)。在轮作中,病害的发展随着返回原地时间的缩短而增加。因此,平均而言,在3年的时间里,将这一时期减少到4到2年,根甲虫的危害程度增加了15.4-19.8%。休播1年复播时,该指标分别为24.4%和27.2%。根据所获得的结果,可以认为,轮作中甜菜浓度的增加导致根分布的增加。

Development of trading activities is carried out in accordance with the current Concept of development of internal trade of Ukraine. At a rapid pace, changes are occurring in consumer preferences, assortment conditions, and the expansion of the influence of the geographical and species capabilities of the presented goods. The analysis of internal changes in the volume of goods turnover of enterprises by product groups, business entities at the country level and its individual regions made it possible to argue and justify the importance of observing the totality of organization principles, the balance of supply and demand, purchasing power, economic feasibility and payback. The used methods of author generalizations, analytical and statistical calculations, comparisons made it possible to systematize the digital material of the study and substantiate conclusions regarding the state and dynamics of the development of trade activities in Ukraine, as well as the Khmelnitsky region, as one of its regions. The study focuses on network marketing, as one of the forms of development and improvement of trade and the determination of the necessary nomenclature and bottlenecks in the activities of trade entities, including markets. The prospects of the use of electronic commerce (purchase and sales) are substantiated, which significantly expands the possibilities for carrying out trading activities for both buyers and trade enterprises. It is proposed to take into account the influence of demographic security, as one of the factors that shape the country's product policy and its export potential. It is determined that the influence on the increase in turnover indicators has an extensive factor in the growth of prices for consumed goods, in a certain way introduces distortions in the perception of digital information. The use of innovative technologies, modern methods of managerial decision-making in the field of marketing, logistics allows us to improve the trading process, satisfy consumer demand and ensure the effectiveness of enterprises in the trading sphere.
贸易活动的发展是按照乌克兰国内贸易发展的现行概念进行的。消费者的偏好、分类条件以及所呈现商品的地理和物种能力的影响正在迅速扩大。按产品组、国家一级的商业实体及其个别区域对企业货物周转量的内部变化进行分析,可以论证和证明遵守组织原则的总体、供需平衡、购买力、经济可行性和回报的重要性。采用作者概括,分析和统计计算,比较的方法使研究的数字材料系统化,并证实有关乌克兰贸易活动发展的状态和动态的结论,以及赫梅利尼茨基地区作为其地区之一。研究的重点是作为发展和改善贸易的一种形式的网络营销,以及确定包括市场在内的贸易实体活动中必要的术语和瓶颈。使用电子商务(采购和销售)的前景得到证实,这大大扩大了买方和贸易企业开展贸易活动的可能性。建议考虑到人口安全的影响,因为这是影响国家产品政策及其出口潜力的因素之一。经确定,对周转指标增加的影响在消费品价格增长中具有广泛的因素,在某种程度上导致对数字信息的感知扭曲。在营销、物流领域使用创新技术、现代管理决策方法,使我们能够改进交易流程,满足消费者需求,确保企业在交易领域的有效性。

Theoretical studies of the milling tillage working body, in particular, dynamic properties under conditions of periodic external load, are substantiated and the main technological parameters are substantiated, and energy performance indicators are analyzed. The following data were adopted as the initial data for theoretical studies of the milling working body: the size of the row-spacing and strips, the dimensional characteristics of the root and stem residues. Theoretical studies of the milling machine gave such justified results: the diameter of the milling drum Dfr.bar = 0.3 m, the rotation frequency of the milling drum nfr.bar = 190 ... 430 hv-1, the number of installed knives on one disk n = 4 pcs, the rotating speed Vob = 6.59 m/s. Rational parameters and operating modes are justified: milling power Nfr = 19.3 kW, torque on the milling drum shaft Mkr = 0.45 kN·m. Theoretically substantiated milling working body is implemented in the development of a combined grinder of plant residues of thick-stem crops. The investigated working body, which performs the technological process of grinding compacted plant residues of thick-stemmed crops with the proposed technology, will allow us to further substantiate in more detail the mathematical model of the combined method of processing the field clogged with plant residues and determine the structural and technological structure of the grinder. The further development of the theoretical foundations of grinding plant residues and soil, in particular milling working bodies used in combined units, has been obtained

The growth of the essential oils market is explained by the growing demand for natural and organic products. Today, the global aromatherapy market with essential oils is growing, and demand for essential oils is increasing at the same rate. The studies are dedicated to the valuable essential oil culture ‒ fennel, the spread of which in the forest-steppe zone of Ukraine will allow to obtain high profitability by agro-forming of different forms of ownership and will help to provide the Ukrainian market with raw materials of appropriate quality. The article offers a solution to the pressing issue of expanding the area of new unconventional culture in the conditions of the Forest-Steppe of Ukraine by improving technological measures in the cultivation of culture. The basis of scientific research is the study of sowing terms (1st decade of April, for soil LTR 6-80C), (2nd decade of April, for LTR of soil 10-120C); row spacing (5, 30, 45 and 60 cm) and seeding rates (1, 1.5 and 2 million sprouting seeds per hectare). Among the plans of the research tasks were: to conduct the accounting of yields and to determine indicators of seeds quality (the content of essential oil in fennel seeds and its conditional yield per hectare of sowing), depending on the studied factors. Crop accounting was performed by continuous submerged threshing. The yield was brought to 100% purity and standard humidity according to the method described by V.O. Moiseychenko and V.O. Yeshchenko. Mathematical data processing was performed according to the method of B.A. Dopehova. The results of the research show that the sowing variants in the first decade of April, with a wide-row method (45 cm) sowing rate of one million sprouting seeds per hectare, yielded the optimum yield of fennel – 1.48 t / ha. In the same variant, the maximum content of essential oil was obtained – 6.23% and its yield from the hectare sowing area‒ 59.2 kg.
精油市场的增长是由于对天然和有机产品的需求不断增长。今天,全球香薰精油市场正在增长,对精油的需求也在以同样的速度增长。这些研究是专门针对有价值的精油文化-茴香,茴香在乌克兰森林草原地区的推广将使其能够通过不同形式的农业所有制获得很高的利润,并将有助于向乌克兰市场提供适当质量的原材料。本文提出了在乌克兰森林草原条件下,通过改进栽培技术措施,扩大新型非常规文化种植面积的紧迫问题。科学研究的基础是播种期的研究(土壤LTR 6-80C为4月1 10年),(土壤LTR 10-120C为4月2 10年);行距(5、30、45和60厘米)和播种率(每公顷1,150和200万颗发芽种子)。研究任务的计划包括:根据所研究的因素进行产量核算和确定种子质量指标(茴香种子中精油的含量及其每公顷播种的条件产量)。作物核算采用连续浸没脱粒法。根据V.O. Moiseychenko和V.O. Yeshchenko描述的方法,将收率提高到100%纯度和标准湿度。根据b.a Dopehova方法对数据进行数学处理。研究结果表明,4月前10年采用宽行法(45 cm)播种量为每公顷100万颗发芽种子的播型,茴香最佳产量为1.48 t /公顷。同一品种精油含量最高为- 6.23%,每公顷播种面积产量为- 59.2 kg。

Among the factors that determine the efficiency and success of the livestock industry is the science-based production of high quality feed. The solution to this problem is impossible without field feed production, engaged in the cultivation of annual mixtures. Among the large number of forage crops in the western forest-steppe are worthy of annual mixtures, in particular winter, which is highly valued for adaptability to growing conditions, especially in climate change. Despite the considerable part of the conducted researches on the development of technology of cultivation of winter forage crops, the question of optimization of their component composition and increase of stability of the most economically valuable species in the conditions of climate change remains relevant.

An important issue in the selection of dairy cattle today is the study of the relationship between hereditary factors that determine the types of proteins in milk. Casein is the main component of milk proteins and is represented by three fractions - alpha (CSN1S1), beta (CSN2) and kappa (CSN3). The content of individual fractions of casein depends on the breed of cows. Genetic variants of kappa-casein are associated with the quality of milk productivity of cows and greater suitability for use of milk for processing and production of cheese. The kappa-casein B allele is associated with the production of milk, the chemical composition of which is more favorable and the technological parameters are more suitable for cheese production. The aim of the work is to assess the genotype of breeding bulls by the kappa-casein gene, which were approved for use in Ukrainian farms in 2020. It was found that most breeding bulls that are approved for use are evaluated by the genotype of kappa-casein. Breeding bulls of Swiss and Jersey breeds have a higher frequency of homozygotes of explosives (100 and 86.2%, respectively). The frequency of allele distribution in the kappa-casein gene in bulls of different breeds was higher in animals of Schwyz (1.00), Jersey (0.931) and Montbeliard breeds (0.813). Among breeding bulls of Holstein breed, no significant difference in milk yield, milk fat and protein between animals of all studied genotypes by kappa-casein and average by breed (among bulls of the catalog) was found. Breeding bulls with the BB genotype had a significant difference with bulls of other genotypes in all studied traits. Therefore, the use of sperm products of bulls approved for use in 2020, with the genotype of explosives for kappa-casein will improve the economically useful traits of offspring, and will contribute to the desired genotype of cows. When choosing bulls, cheese makers should pay attention not only to protein and somatic cell count (SCS). It is also important to have a high percentage of BB cows in the herd
当今选择奶牛的一个重要问题是研究决定牛奶中蛋白质类型的遗传因素之间的关系。酪蛋白是乳蛋白的主要成分,由α (CSN1S1)、β (CSN2)和kappa (CSN3)三个部分组成。酪蛋白各组分的含量取决于奶牛的品种。kappa-酪蛋白的遗传变异与奶牛的产奶质量和更适合使用牛奶加工和生产奶酪有关。kappa-酪蛋白B等位基因与牛奶的生产有关,其化学成分更有利,工艺参数更适合奶酪生产。这项工作的目的是通过kappa-酪蛋白基因评估种牛的基因型,该基因于2020年被批准在乌克兰农场使用。研究发现,大多数被批准使用的种牛都是通过卡帕酪蛋白基因型进行评价的。瑞士种和泽西种的种公牛炸药纯合子率较高(分别为100%和86.2%)。不同品种公牛kappa-酪蛋白基因等位基因分布频率以施维兹(1.00)、泽西(0.931)和蒙贝利亚(0.813)较高。在荷斯坦种种公牛中,各基因型动物的产奶量、乳脂和乳蛋白与各品种(在目录公牛中)的平均值均无显著差异。BB基因型种牛的各项性状均与其他基因型种牛有显著差异。因此,使用2020年批准使用的公牛精子产品,其基因型为kappa-酪蛋白炸药,将改善后代的经济有用性状,并将有助于奶牛的理想基因型。在选择公牛时,奶酪制造商不仅要注意蛋白质和体细胞计数(SCS)。在奶牛群中有较高比例的BB牛也很重要

Molecular genetic markers can detect polymorphism at the DNA level. This feature determines the possibility of their widespread use in genetics and breeding. Alleles of the BoLA-DRB3 gene (exon 2) can act as such markers if a statically significant association between the disease and the allele is established. The presence of such DNA markers in the genotype of animals makes it possible to judge the likelihood of disease in postnatal ontogenesis immediately after the birth of a heifer, based on which we can conclude about the conditions of further use of the animal in the main herd. According to the results of studying the polymorphism of the BoLA-DRB3 gene in cows of the Ukrainian black and white dairy breed resistant and susceptible to necrobacteriosis, four "informative" alleles were revealed. Two of them *03 and *22 are associated with resistance, and the other two - *16 and *23 with susceptibility to necrobacteriosis. The presence of these alleles in the genotype of the animal is determined by testing performed by PCR-RFLP. The method is time consuming, labor intensive and costly. To simplify it, the following technique is proposed. Restriction fragments of alleles *03, *16, *22 and *23 for endocluases RsaI, XhoII and HaeIII have the following DNA patterns: bbb, jbd, mba and nba. Due to the peculiarity of the restriction fragments, which is that endonuclease XhoII reveals in these alleles only one pattern b with length of 284 bp, the process of determining informative alleles can be simplified. Isolation of DNA from blood samples and amplification of a fragment of the BoLA-DRB3.2 gene with a size of 284 bp is carried out according to the established technique. Next, the restriction of the fragment by endonuclease XhoII and sampling having a pattern b. Selected samples are treated with RsaI endonuclease and only those with patterns b, j, m and n remain. The next step is to restrict the selected samples with HaeIII endonuclease and select heifers with bbb (*03) and nba (*23) genotypes. After the first restriction, blood samples without pattern b are eliminated from the experimental sample; after the second – two alleles with patterns RsaI + XhoII jb (*16) and mb (*22) are unambiguously determined, after the third – genotypes bbb and nba, which correspond to alleles *03 and *23. In total, only 75% of blood samples are typed, which reduces the material consumption, time and cost of work to identify heifers genetically susceptible (resistant) to necrobacteriosis.
分子遗传标记可以检测DNA水平上的多态性。这一特性决定了它们在遗传学和育种中广泛应用的可能性。BoLA-DRB3基因(外显子2)的等位基因可以作为这样的标记,如果在疾病和等位基因之间建立了静态显著的关联。在动物的基因型中存在这种DNA标记,可以在小母牛出生后立即判断出产后个体发生疾病的可能性,根据这一点,我们可以得出在主要畜群中进一步使用该动物的条件。根据对乌克兰黑、白奶牛抗、易感坏死性细菌病BoLA-DRB3基因多态性的研究结果,发现了4个“信息性”等位基因。其中*03和*22与耐药相关,*16和*23与坏死菌病易感性相关。这些等位基因在动物基因型中的存在是通过PCR-RFLP检测确定的。该方法耗时长,劳动强度大,成本高。为了简化它,提出了以下技术。内切酶RsaI、XhoII和HaeIII的*03、*16、*22和*23等位基因的限制性片段具有bbb、jbd、mba和nba等DNA模式。由于限制性内切酶XhoII在这些等位基因中只显示一种长度为284 bp的模式b,因此可以简化信息等位基因的确定过程。根据已建立的技术,从血样中分离DNA并扩增大小为284 bp的BoLA-DRB3.2基因片段。接下来,用内切酶XhoII限制片段,取样模式为b。选定的样本用RsaI内切酶处理,只保留模式为b、j、m和n的样本。下一步是用HaeIII核酸内切酶对所选样品进行限制,选择bbb(*03)和nba(*23)基因型的母牛。经过第一次限制后,从实验样本中剔除无模式b的血液样本;第二种RsaI + XhoII基因型分别为jb(*16)和mb(*22),第三种基因型分别为bbb和nba(对应等位基因*03和*23)。总的来说,只有75%的血液样本被分型,这减少了材料消耗、时间和工作成本,以确定对坏死性细菌病遗传易感(耐药)的小母牛。

During the development of mastitis in cows, the formation of a biofilm pathogen is an effective way to preserve it in the microenvironment of mammary gland. Biofilm infections are difficult to treat with antimicrobials, and bacterial resistance to antibiotics increases to 1000-fold level, compared with what is observed when grown in planktonic conditions. The aim of study – to determine and compare the effect of antimicrobial drugs and bacteriophage Phage SAvB14 in the destruction of biofilms formed by S. aureus var. bovis. Isolation and species identification of staphylococci were performed according to conventional methods using BD Baird-Parker Agar medium (HiMedia, India). Determination of ability of staphylococci to form biofilms and the number of viable bacteria was determined by the Stepanovic method. The study of sensitivity of microorganisms in biofilm form was performed on daily microbial biofilms grown in plastic Petri dishes. After 24 hours of incubation of cultures, the dishes were washed three times from planktonic (unattached) microorganisms with sterile phosphate buffer and introduced the studied antibacterial agents. After exposure, the dishes were washed three times with sterile phosphate buffer, introduced 5 cm3 of sterile 0.9% sodium chloride solution and washed the biofilm, took 1.0 cm3 of suspension, prepared a series of ten-fold dilutions, inoculated 1.0 cm3 of each dilution in Petri dishes, poured MPA and incubated at temperature of 370C for 24–48 hours to determine the number of bacteria. In determining the effect of antibiotics on bacterial biofilms, it was found that of the studied antibiotics, enrofloxacin worked best probably due to its low molecular weight and ability to penetrate the pores and channels of the biofilm to microbial cells. After the action of enrofloxacin on biofilms, staphylococcal bacteria were completely inactivated. Also, the antibiotics ceftriaxone and doxycycline were effective against bacteria in biofilms. After the action of ceftriaxone, the number of surviving bacteria was lg 1.9 ± 1.1 CFU/cm2 of biofilm area, and doxycycline lg 2.5 ± 1.2 CFU/cm2. At the same time, under the action of antibiotics penicillins, aminoglycosides and macrolides, the number of surviving microbial cells was about lg 5.3 CFU/cm2 of biofilm area. In studies on the effect of bacteriophage Phage SAvB14 on biofilms formed by S. aureus var. bovis, there was their degradation. At this, viable microbial cells from the biofilm were not isolated. In this case, we can say that the phages penetrated and reached the staphylococcal cells throughout the thickness of biofilm and bacteria were susceptible to this phage. That is, there was a passive treatment of biofilm with phages, in which lysis depended on the rate of virus uptake. Therefore, the obtained results of laboratory studies indicate the prospects of effective use of our selected specific staphylococcal bacteriophage Phage SAvB14 for the destruction of biofilm formed by S.
在奶牛乳腺炎的发展过程中,生物膜病原体的形成是在乳腺微环境中保存乳腺炎的有效途径。生物膜感染很难用抗菌剂治疗,细菌对抗生素的耐药性增加到浮游生物条件下生长时的1000倍。本研究的目的是确定并比较抗菌药物和噬菌体噬菌体SAvB14对牛金黄色葡萄球菌形成的生物膜的破坏作用。使用Baird-Parker琼脂培养基(HiMedia, India),按照常规方法分离和鉴定葡萄球菌。采用Stepanovic法测定葡萄球菌形成生物膜的能力和活菌数量。对生长在塑料培养皿中的微生物生物膜进行了生物膜形式的敏感性研究。培养物孵育24小时后,用无菌磷酸盐缓冲液将培养皿从浮游(未附着)微生物中洗涤三次,并加入所研究的抗菌剂。暴露后,用无菌磷酸盐缓冲液洗涤3次培养皿,加入5 cm3的0.9%氯化钠无菌溶液,洗涤生物膜,取1.0 cm3悬浮液,配制一系列10倍稀释液,在培养皿中接种每种稀释液1.0 cm3,倒入MPA,在370C温度下孵育24-48小时,测定细菌数量。在确定抗生素对细菌生物膜的影响时,发现在所研究的抗生素中,恩诺沙星的效果最好,可能是由于其低分子量和能够穿透生物膜的孔和通道进入微生物细胞。恩诺沙星作用于生物膜后,葡萄球菌完全失活。头孢曲松和强力霉素对生物膜细菌有较好的抑菌效果。头孢曲松作用后,存活菌数为1.9±1.1 CFU/cm2,强力霉素为2.5±1.2 CFU/cm2。同时,在抗生素青霉素类、氨基糖苷类和大环内酯类的作用下,存活的微生物细胞数约为5.3 CFU/cm2。在研究噬菌体噬菌体SAvB14对金黄色葡萄球菌变种牛形成的生物膜的作用时,发现了它们的降解作用。在这种情况下,从生物膜中没有分离出活微生物细胞。在这种情况下,我们可以说噬菌体穿透并到达葡萄球菌细胞的整个生物膜厚度,细菌对该噬菌体敏感。也就是说,噬菌体对生物膜进行被动处理,其中裂解取决于病毒摄取的速度。因此,实验室研究结果表明,我们选择的特异性葡萄球菌噬菌体噬菌体SAvB14可以有效地破坏奶牛乳腺炎中金黄色葡萄球菌变异形成的生物膜。

A GROUND IS AS EMITTER FOR TREATMENT OF ENDOMETRITU OF ZOONS 用于动物子宫内膜炎的治疗

The article proposes to experimentally investigate the corrugated conical emitter in order to confirm the theoretical calculations of the reflection coefficient of the electromagnetic field from the opening of the investigated corrugated conical emitter. Research is based on the influence of electromagnetic fields on the physicochemical processes in biological objects. Theoretical studies have shown that for industrial use requires a radiator with a frequency range of 30-31 GHz and a diameter of not more than 30 mm, which should provide a width of the radiation pattern within 24-30 mm. For practical purposes, it is necessary to estimate the reflection coefficient of the calculated corrugated emitter. For the study we use a conical corrugated irradiator, the length of which from the opening to the phase center is 21 mm. The diameter of the radiating aperture is 25 mm. The basic geometrical parameters of the corrugation: h = 2.5 mm, c = 1.25 mm, b = 1.25 mm. To feed the transmitter under consideration, a transition from a rectangular waveguide with a cross section of 7.2 × 3.4 mm to a circular diameter of 7 mm is used. Measurements were made at 30 GHz. Since the modulus of the reflection coefficient of the emitter must be close to zero, the method of reflectometer must be used for accurate measurements
本文提出对波纹锥形发射极进行实验研究,以验证波纹锥形发射极开口处电磁场反射系数的理论计算。研究的基础是电磁场对生物物体的物理化学过程的影响。理论研究表明,工业用途的辐射器需要频率范围为30-31千兆赫,直径不超过30毫米,其辐射方向图的宽度应在24-30毫米之间。在实际应用中,有必要对计算出的波形发射极的反射系数进行估算。在研究中,我们使用了圆锥形波纹辐射器,其从开口到相中心的长度为21 mm。辐射孔直径为25mm。波纹的基本几何参数:h = 2.5 mm, c = 1.25 mm, b = 1.25 mm。为了馈送考虑中的发射机,使用了从横截面为7.2 × 3.4 mm的矩形波导到直径为7 mm的圆形波导的过渡。测量是在30 GHz进行的。由于发射器反射系数的模量必须接近于零,因此必须使用反射计的方法进行精确测量

Research is based on the influence of electromagnetic fields on the physicochemical processes in biological objects. Theoretical studies have shown that for industrial use requires a radiator with a frequency range of 30-31 GHz and a diameter of not more than 30 mm, which should provide a width of the radiation pattern within 24-30 mm. For practical purposes, it is necessary to estimate the reflection coefficient of the calculated corrugated emitter. For the study we use a conical corrugated irradiator, the length of which from the opening to the phase center is 21 mm. The diameter of the radiating aperture is 25 mm. The basic geometrical parameters of the corrugation: h = 2.5 mm, c = 1.25 mm, b = 1.25 mm.
