“…21,22 Both of these types of stress result in mass transport of Sn atoms from the highly stressed region to the whisker root; this is generally accepted as the phenomenon driving growth of tin whiskers and hillocks. 18,21 Because stress, global or local, also depends on crystallographic texture, which may be predominantly determined by electrodeposition process conditions, for example current density, deposition temperature, bath agitation, etc., [23][24][25][26][27] it is important to study such correlations; we summarize below various reports addressing these issues.…”

The effects of two major electrodeposition process conditions, electrolyte bath temperature and current density, on the microstructure and crystallographic texture of pure tin coatings on brass and, ultimately, on the extent of whisker formation have been examined. The grain size of the deposited coatings increased with increasing electrolyte bath temperature and current density, which significantly affected the dominant texture: (211) or (420) was the dominant texture at low current densities whereas, depending on deposition temperature, (200) or (220) became the dominant texture at high current densities. After deposition, coatings were subjected to different environmental conditions, for example isothermal aging (room temperature, 50°C, or 150°C) for up to 90 days and thermal cycling between À25°C and 85°C for 100 cycles, and whisker growth was studied. The Sn coatings with low Miller index planes, for example (200) and (220), and with moderate aging temperature were more prone to whiskering than coating with high Miller index planes, for example (420), and high aging temperature. A processing route involving the optimum combination of current density and deposition temperature is proposed for suppressing whisker growth.

“…1). The marine Lower Cretaceous section, containing a rich invertebrate fauna, has been described repeatedly in the literature (Pavlow and Lamplugh, 1892;Pavlow, 1901;Chernova, 1951;Sazonova, 1958;Glazunova, 1967Glazunova, , 1973Myatlyuk, 1984;Baraboshkin et al, 2001;Guzhikov, Baraboshkin, and Birbina, 2003;Blagovetshenskiy and Shumilkin, 2006a, b;Baraboshkin and Blagovetshenskiy, 2010). The section at Slantsevy Rudnik represents the upper part of the Hauterivian with a total thickness of 38.8 m (Baraboshkin and Blagovetshenskiy, 2010).…”

“…1). These deposits are referred to the ammonite Speetoniceras versicolor Zone, the lower of the three ammonite zones of the upper Hauterivian (Pavlow, 1901;Glazunova, 1967;Baraboshkin and Blagovetshenskiy, 2010). UPM 976 was found in the dark gray shales and siltites of the g-3.1 horizon, in the lower part of the Speetoniceras versicolor Zone (Fig.…”

Volgatitan simbirskiensis, gen. et sp. nov., is described based on a series of anterior and middle caudal vertebrae from a single individual discovered in the Lower Cretaceous (upper Hauterivian, Speetoniceras versicolor ammonite Zone) marine deposits at Slantsevy Rudnik vertebrate locality near Ulyanovsk City, Russia. The new taxon is characterized by strongly procoelous anterior and middle caudal vertebrae, a long centrum of the first caudal vertebra, a strong ventral ridge in the anterior and middle caudal vertebrae, a neural arch positioned at the anterior half of the centrum, hyposphene-hypantrum articulation in the anterior caudal vertebrae, and somphospondylous bone texture. Phylogenetic analysis places the new taxon as a lithostrotian titanosaur, a basal member of the lineage leading to the Lognkosauria. This lineage previously contained only South American taxa with body mass reaching 60-70 tons. Volgatitan gen. nov. is the first European and the geologically oldest representative of this lineage. Its body mass is estimated as 17.3 tons. Discovery of Volgatitan gen. nov. suggests that the lithostrotian lineage leading to the Lognkosauria had a wider distribution in the Early Cretaceous and became extinct everywhere except South America by the end of the Early Cretaceous.

The purpose. To study fytosanitory state of sowings of winter wheat at different systems of fertilizing with the purpose of optimization of system of its protection against illnesses and pests. Methods. Field, laboratory, analysis of variance. Results. Results of long-term researches in fytosanitory state of sowings of winter wheat are presented at different systems of fertilizing, and the expediency of chemical crop protection during vegetation is justified. Conclusions. It is fixed that application of collateral products of the pease, the moderate doses of artificial fertilizers, in particular nitrogenous in dose of 60-120 kg/hectare at ratio of nitrogen and potassium 1,3:1 in techniques of growing of winter wheat ensures congenial fytosanitory state of sowings and restricts application of fungicides and disinsectants during vegetation of crop. Use of large doses of artificial fertilizers (N300P150K150; N120, N240P80K100 and N180P135K135) promotes increase of numerosity of pathogenic fungi in soil, reinforces strikeness of plants with root rots, floury dew, septoria spot of leaves, invading with sucking pests that causes intense chemical protection of plants. Key words: winter wheat, phytopathogenic complex, phytophags, pathogenic mycoflora of soil, artificial fertilizers, collateral products of the predecessor, chemical protection.Comprehensively reasonable use of fertilizers is very important prerequisite for optimizing how technology growing winter wheat in a whole, as its component of integrated plant protection from harmful objects. Fertilizers effect on winter wheat communities and are one of the important factors from which depends the condition of both plants and pests. This effect appears in the microclimate changes in crops, morphological and physiological characteristics of plants, shifting phenological stages of their development, and it is already create conditions for oscillations in a rather wide range of levels of development and reproduction of pests and diseases [1,2].The use of phosphorus-potassium fertilizers traditionally considered an important measure that improves the phytosanitarycondition ofagrocenoses [3]. It is known that phosphorus-potassium fertilizers promote plant resistance, and excess nitrogen leads to increased reproduction of aphids, mites and other pests and diseases [4,5, 6]. Of particular importance are potash fertilizers. Increased potassium nutrition of plants provides the formation of their stronger skeletal tissuesandalso cell wall and cuticle that prevents penetration into the cell phytopathogens. Given sufficientpotassiumNutrition in plants activates the biosynthesis of phenolic compoundsthen play an important role in plant immunity [7,8,9].On the other hand, nitrogen fertilizers, creating excess nitrates in the soil, increase its conductive properties, resulting inphytopathogenicmicromyceta are not only superior but also capable under optimal conditions actively infect susceptible plants. Moreover, according to V.О.Chulkyna and others (2009), with an excess of nitr...
