In the article, data on the distribution of anoplodsefalidosis of horses are given. Anoplodsefalidozy horses are widely distributed in the northern and central zones of the Republic of Sakha (Yakutia). The species composition of these cestodes is represented by 3 species: Anoplocephala magna, Anoplocephala perfoliata and Paranoplocephala mamillana. Of the 10 species of oribatid ticks found in the pastures of six species, anoploccephalidae, Achheteria coleoptrata, Scheloribates latipes, Scheloribates laevigatus, Galumna obvia, Ceratosetoides cisalpinus, Testocepheus velatus have been registered as intermediate hosts. The highest reproductive activity of oribatids occurs in May-June, which contributes to the massive infection of horses. In laboratory conditions, at a temperature of 28̊C and a relative humidity of 70-80 %, cysticercoids in mites form in 35-40 days.

The variation of the color intensity of the chromatophores present in the wings of Schistocerca americana was analyzed by exposing 31 specimens to thermal transitions within the range of 45 - 5 °C.  The adult specimens were collected using a mini-terrarium of dimensions 40x40x30 cm. As a substrate, a layer of soil, stones, and finally a layer of grass were used along with branches of bushes and leaves; hydroponic lettuce, cabbage and the grass were used as food for the specimens. Optical microscopy of the wings of the insects was used for live observation without coverslips or contrasting substances. At 45°C, degradation of color intensity was observed in the chromatophores present in the wings. At 5°C, chromatophores intensify their color to brownish-black. This temperature was the extreme minimum that S. americana could tolerate. We found negative correlation between the temperature and the degree of darkness (R2 = 0.8038). Our results are in accordance with a previously published study in which Phaulacridium vittatum was examined, as the decrease of temperature caused darkening color change in melanin-type chromatophores. The present investigation can be considered as the first initial study of its kind for S. americana, in terms of examining the changes in the color intensity of the chromatophores present in the wings caused by thermal transition under laboratory conditions.

The purpose of the research is to study the lifespan of Lipoptena cervi imaginal forms under exposure of different temperature conditions and humidity. Materials and methods. L. cervi caught in natural habitats and taken off from marals’ skin served as the material for the research. Overall, 38 samplings have been conducted, 18 thousand L. cervi have been sampled. Caught imagoes were put into mattresses after suffocation with ether-chloroform mixture; the most viable insects were used in experiments. Research for L. cervi lifespan except host of volatiles (not fed) and taken off from marals were conducted under exposure of different temperature conditions and humidity as well as in different types of cages, in wool on skins that were taken off. L. cervi were kept in small quantities in free cages made of capron mesh. Results and discussion. The winged forms under mid-mountain zone conditions of the Republic of Altai can be seen from June up to October; wingless forms (on the feeders’ body) can be seen from June of the current year up to June of the following year and including. Chrysalides are present in nature throughout the year, as L. cervi can’t hatch out from chrysalides of the previous year generation fast enough in June and July before the chrysalides of the new generation begin to appear. The weight of the hatched out L. cervi is 7.9-11.5 mg, they die if the weight is decreased up to 3.0-3.9 mg. It would appear that, the energy and water reserve is 4.9-7.6 mg per one insect. Young not fed L. cervi live rather longer than sexually mature insects. The L. cervi lifespan reliably increases without food as the humidity increases. The longest lifespan is when the humidity is about 60-80% and temperature is about 14-16°С. In laboratory conditions, at the air temperature of about 20-25°C, the humidity of about 60-80%, and moderate airing the chrysalis development lasts for 90 days on the average.

Human Gametes

Significant advances in cryogenic technology render it possible to freeze and store human gametes. Under appropriate laboratory conditions frozen gametes can remain viable for long periods of time. In consequence, it is possible for a child to be conceived and procreated after the death of one or both parents. This raises some challenging juristic problems. Amongst these are implications for the law of inheritance. Where a valid will expressly refers to a child who will be procreated after the testator's death, the child's right to inherit will be secured. However, where a will merely refers to children as a class, or with intestate succession, it becomes uncertain whether a posthumously procreated child has a right to inherit. South African legislation governing succession, the common law and the Constitution of the Republic of South Africa, 1996 all fail to provide definitive answers. Because of this and as the numbers of posthumously procreated children are likely to increase as artificial reproduction services become more widely available, there is a need for South African legislation to clarify their inheritance rights.

The aim of the research is the selection and justification of the combined gravity method of enrichment of refractory gold-bearing raw materials and the hydro and pyrometallurgical method of processing enrichment products based on the study of the technological properties of the feedstock and enrichment products in the mineral and raw materials complex of the deposit located on the territory of the Republic of Kazakhstan. There is a tendency to increase the imbalance between mining and also the increase in off-balance reserves of gold-bearing ores, which ultimately poses a serious problem for the development of the country’s economy. Research on the development of technology for the extraction of gold from refractory ores has been performed on three samples of the Vasilkovsky stockwork deposit. The ores are persistent in the presence of arsenic (arsenopyrite) and finely divided gold, a significant part of which is in the form associated with both sulfides (mainly arsenopyrite) and rockforming minerals.

This study’s objective was to determine if there was a difference in aggressiveness between the Diaporthe longicolla and the Diaporthe pseudolongicolla isolates infecting the soybean seeds. An artificial inoculation was performed under laboratory conditions and in a greenhouse on a soybean cultivar (Tisa) created in the breeding program of the Agricultural Institute Osijek and represented in a large-scale production in the Republic of Croatia. An attempt was made to discover whether the isolates of the recently described D. pseudolongicolla were more aggressive to the soybean seeds than the D. longicolla isolates, which have manifested a high aggressiveness to the soybean seeds throughout a series of earlier experiments. The D. pseudolongicolla isolates used in the experiment were isolated from the infected seeds pertaining to a wide production in the vicinity of Osijek. The experiments have demonstrated that there were statistically significant differences (P<0.05) in the aggressiveness between the isolates tested, with the D. longicolla isolate manifesting the highest aggressiveness in both trials.
