The article presents field research results on the effectiveness of different moisture and nutrition conditions at the cultivation of early potato under drip irrigation in southern Ukraine. The scheme of the experiment included the treatment with the complex Mochevyn K as an additional control and different methods and correlation of fertilizers Plantafol (treatment of tubers before planting, fertilizing, at budding and their combination), as well as different soil moisture conditions (irrigation rates of 100 and 200 m?/ha). Studies have shown that the average yield of early potato without irrigation was 10.44 t/ha. Moisture conditions significantly affected the yield of young tubers - irrigation at a rate of 200 m?/ha provided 21.61 t/ha, whereas reducing the irrigation rate to 100 m?/ha led to a decrease in yield - 19.86 t/ha. The first treatment of planting tubers, treatment of plants at sprouting and during budding provided almost the same yield. The second and the third treatments of plants and tubers did not lead to a significant increase in yield. The highest productivity of potato was provided by Plantafol treatment of tubers and combination of tuber treatment with foliar feeding at mass sprouting phase with a 200 m?/ha irrigation rate for two years: 24.16 and 23.22 t/ha.

The paper presents the materials of field research on the study of the regularities of the development of moisture outlines on light soils during drip irrigation of vegetable crops. The correlation is found between the depth of the moistened layer and the area of the moistening outlines on the pre-irrigation threshold of the moisture content of the active soil layer, irrigation standards and the flow rate of drippers, which gives an opportunity to decline the unproductive water consumption for filtration. It is found that in light loamy and sandy loam light chestnut soils, for guaranteed rule of the moisture regime, on onion crops, it is essential to maintain the pre-irrigation threshold of 80% HB with the irrigation rate of 200 m3 / ha with the flow rate of drip water outlets of 2.8 l / h, and the depth of irrigation of 120 m3/ha with the flow rate of discharge outlets of 1.7 l/h, correspondingly. In irrigation of tomatoes grown on light-loamy light-chestnut soils, it is appropriate to apply the irrigation rate of 180 m3 / ha, which provides the level of pre-irrigation humidity in the layer of 0.6 m not lower than 80% HB, the formation of the required characteristics of the moisture contour (depth of 0.62 m and diameter of 0.37 m), as well as an enhance in the efficiency of irrigation water use by 11.1%. The results can be applied in the design of drip irrigation systems for vegetable crops.

Zakat is an act of worship contained in the pillars of Islam. In the pillars of Islam, tithing is in the third place after prayer. The management of zakat funds aims to increase the usability and efficiency of zakat which has an impact on the realization of justice, community welfare and poverty alleviation in the vicinity. The Amil Fund Allocation in Bandar Lampung City has increased from 2018-2020. In managing the allocation of amil funds, the greater the zakat collection, the greater the allocation of amil rights funds. The research conducted by the author is (Field Research), direct research is carried out in the field using respondent data. Zakat assets funds that occur in BAZNAS Bandar Lampung city have not been maximized for amil rights, because the collection that occurs at BAZNAS Bandar City funds infaq shodaqah is greater than zakat assets. Therefore, to fulfill amil rights, BAZNAS Bandar Lampung City uses infaq shodaqah funds to fulfill amil rights. Keywords: Amil Fund, Zakat Management, Sharia Economic Law

Precipitation Formation

This article describes concepts of three features of microstructure–properties relationship, first the imaging and formation of nano-particles, then their contribution to hardness, and finally hydrogen embrittlement during fatigue. First, we briefly review the imaging modes in transmission electron microscopy (TEM) for nano-sized precipitates. The next issue is the hardening in Aluminum alloys, which is caused by GP-zones or precipitates, formed at the second step of the annealing process. After homogenization, the peak-hardness can be generally achieved by a few hours of annealing between 120°C and 200°C. Hardness measurements and equal-channel axial pressing (ECAP) showed that even at room temperature the driving force for formation of the particles is so strong that already within one hour of annealing after homogenization a remarkable hardening occurs. The third issue, hydrogen embrittlement, is caused by oxidation of pure Al surfaces produced at the crack tip during fatigue under ambient or wet moisture conditions. The cracks propagate preferentially along the precipitation free zone adjacent to grain boundaries, where hydrogen diffusion is fastest.

AbstractBy conducting field research and analysing judgments delivered in Beijing courts from 2004 to 2011, we find that the popular notion held by China's trade partners of the inadequacy of intellectual property protection is only partly supported by the empirical evidence. The likelihood of winning lawsuits is higher for foreign than domestic plaintiffs and the extremely low damages ruled by Chinese courts are due to particular causes. Courts lack consistent methods to calculate incurred losses in intellectual property right (IPR) infringements and consequently routinely apply the statutory damages whose upper limit is restricted by legislation. Efforts by Chinese legislators to enhance compensation by lifting the upper limit of awardable statutory damages in the Third Amendment of Chinese Patent Law (2008) did not seem to have an effect on our sample. Chinese policymakers should instead focus on the cause of the issue by providing more implementable guidelines for courts to calculate losses. Courts need to develop applicable conventions for calculating damages, based on objective criteria of how much compensation ought to be payable, which is also the basis of calculating reasonable statutory damages. Thus, the new provision of the “right of information” on pirated goods proposed by the ongoing Fourth Amendment provides a significant weapon to combat counterfeiting.

Annual Weeds

Annual weeds were allowed to compete until or after each of the first three postemergence irrigations of furrow-irrigated cotton (Gossypium hirsutumL. ‘Deltapine 16’). Beds and furrows were shaped with a sectioned, rolling cultivator three times between cotton emergence and the second irrigation. Cotton boll components and fiber properties were not affected by periods of competition with annual weeds. Weeds allowed to compete after the first or second irrigations significantly reduced the 4-year average yield of cotton by 16 and 12%, respectively. Competition that began after the third or fourth irrigation, or that ended after the first, second, or third irrigation was less detrimental and did not significantly affect yields.

ABSTRACTBetween 1898 and 1905, three American expeditions attempted to reach the geographical North Pole from the archipelago of Zemlya Frantsa-Iosifa [Franz Josef Land] and each went to extraordinary and expensive lengths to stage their work. The third of these, the Ziegler polar expedition (1903–1905), led by Anthony Fiala and funded by the American baking soda tycoon William Ziegler, set up numerous camps and caches of supplies along its various expedition routes through the islands. The papers of Anton Vedoe and Ernest Leffingwell at the Rauner Special Collections Library at Dartmouth College reveal both the locations and contents of the caches Fiala ordered to be established in spring 1905, as he made his second and final attempt to reach the pole. These caches extend from the expedition base camp (Camp Abruzzi) at Bukhta Teplitsa [Teplitz Bay] on Ostrov Rudol'fa [Rudolf Island] to the main base of the preceding 1901–1902 Baldwin-Ziegler expedition (Camp Ziegler) on Ostrov Aldzher [Alger Island]. Little is known of the condition of these sites, especially the main cache site of Kane Lodge on Ostrov Grili [Greely Island]. As such, they hold the potential to provide new sources of archaeological data to study American polar ambitions at the turn of the 20th century. While these sites remain unexplored, increasing tourism in the islands necessitates informed planning and field research to establish the nature and stability of these remains so that they may be preserved and the potential effects of tourism mitigated.

AbstractThe effects of various levels of infestation of the corn leaf aphid, Rhopalosiphum maidis (Fitch), on yield of field corn were examined from 1965 to 1970 inclusive when all plants whose yield might have been influenced by factors other than aphid feeding were excluded from the data. A possible relationship between moisture stress in plants and degree of aphid injury was also investigated.A light infestation (maximum of 400 aphids on the tassel) caused average yield reductions up to 8.3% when plants were under moisture stress, but nil to negligible losses when moisture was adequate. Moderate infestations (many hundreds of aphids on part of the tassel) produced average losses up to 34.8% under drought conditions and up to 11.8% when moisture was abundant. Severe infestations (many hundreds of aphids on most of the tassel) caused average yield reductions ranging from 43.2 to 91.8% when plants were under water stress and up to 58.9% even with abundant moisture. Very severely infested plants (many hundreds on all of the tassel and whorl leaves) were usually barren or had ears with just a few kernels regardless of moisture conditions.Most injury from aphid feeding appeared to occur before and during pollination. No particular combination of temperature and rainfall favored aphid buildup.

Orchard densities from 833 to 2500 trees/ha were studied on sod-podzolic soil (annual precipitation 550 mm). An orchard was planted in Spring 1990 and 1991 using 2-year-old nursery trees grown in film containers. The interval between trees in the row was 1 to 1.5 to 2 to 2.5 and 3 m. The trees were grafted on dwarf rootstock (62-396) and semi-dwarf (54-118). The commercial fruiting of `Tellisaare' began the third year after planting, `Antey' the fourth, and Spartan at fifth. The initial yield of `Antey in the most dense treatment was 14.5 t·ha–1, `Tellisaare' was 15 to 22 t·ha–1, according to rootstocks. Average yield of `Antey' on 62-396 for 1992–95 at the orchard density of 2500 trees/ha was 10 t·ha–1·year–1 and on rootstock of 54-118 it was 21 t·ha–1. However, yield of `Tellisaare' 54-118 for 1992–1995 was 13 to 15 t·ha–1 in all treatment of orchard density from 1666 to 833 trees/ha. The annual yield of this cultivar grafted on rootstock 54-118 at a tree density of 2500 plants/ha increased to 18.3 t·ha–1.

Abstract Presentation of contemporary trends in development of such residential units as peripheral housing estates in large Polish cities, as exemplified by Warsaw, is the objective of the paper. Such units are compared with their counterparts being built in Berlin. Research was carried out in three housing estates in the western part of the Bemowo District of Warsaw, i.e. Lazurowa (developer J.W. Construction), Nad Jeziorem (developer DoR Group) and Villa L’Azur (developer Bouygues Immobilier Polska). The first two were completed at the turn of 2008/2009. The third is in the final stage of construction. All three are located inside immediate city borders. Within framework of research were carried out analysis of developers’ materials, cartographic materials from the City Hall as well as field research. The results were juxtaposed with research made in 2008 in Berlin.
