Comparison of the chemical composition of domestic common hornbeam (Carpinus betulus L.) wood and exotic yakal (Shorea astylosa Foxw.) wood. The study was carried out to compare the chemical composition of domestic hornbeam wood with exotic yakal wood, which is an endemic species occurring in the Philippines. Species of similar structural structure occurring in different areas were studied. Extractives, cellulose (including α-cellulose), holocellulose (including hemicelluloses), lignin and ash contents were analyzed. The obtained results indicated lower content of cellulose, α-cellulose, lignin, extractives and ash in hornbeam wood as compared to yakal wood. On the other hand, a much higher amount of hemicelluloses (by 12 percentage points) was found in hornbeam wood. Probably, the main reason for the differences in the chemical composition of wood were different habitat and climatic conditions, in which the studied species were growing.

The harsh climatic conditions of the coast of the Tatar Strait make explainable the large number of patients with frostbite who passed under our supervision during the winter of 1935-36 and amounted to 2.8% (26 people) of the total contingent of inpatients. The variety of recommended methods for treating frostbite, on the one hand, and the relatively long recovery period for all of them, on the other hand, made us take a critical approach to the proposed methods of treatment. All currently existing methods are reduced to the treatment of frostbite areas with bandages; and on the locus morbi apply indifferent or slightly disinfecting ointments, or a similar property of a powder, or wipes moistened with slightly disinfecting solutions, for example, Sol. kalii hyperm. 1: 1000. The apparent similarity of the external manifestations of frostbite and burns inspired us with the idea of ​​conducting frostbite therapy in an "open way", which has long occupied a well-deserved place in the treatment of burns.

The essential oils obtained by hydrodistillation of the aerial parts of Valeriana parviflora (Trevir) BM Vadillo, an endemic species of the Venezuelan Andes, collected from the same location in two different seasons (dry and rainy) of the year, were analyzed by GC/MS. The essential oil obtained during the dry season showed linalool (11.9%), eugenol (8.9%), p-menth-1-en-9-al (8.7%) and α-terpineol (7.7%) as main components, while the oil obtained from the rainy season collection showed o-xylol (16.2%), 3-methyl isovaleric acid (10.6%) and geranial (9.5%) as major compounds. Some of the differences in the composition of these oils might be due to the climatic conditions at the time of harvesting.

AbstractThe youngest low-mass protostars are known to be chemically rich, accreting matter most vigorously, and producing the most powerful outflows. Molecules are unique tracers of these phenomena. We use ALMA to study several outflow sources in the Serpens Main region. The most luminous source, Ser-SMM1, shows the richest chemical composition, but some complex molecules are also present in S68N. No emission from complex organics is detected toward Ser-emb 8N, which is the least luminous in the sample. We discuss whether these differences reflect an evolutionary effect or whether they are due to different physical structures. We also analyze the outflow structure from these young protostars by comparing emission of CO and SiO. EHV molecular jets originating from SMM1-a,b and Ser-emb 8N contrast with no such activity from S68N, which on the other hand presents a complex outflow structure.

В статье впервые публикуются серебряные монеты конца 6 середины 5 в. до н.э. из раскопок Фанагории. Этот нумизматический материал имеет важное значение для уточнения датировки слоев поздней архаики ранней классики на акрополе Фанагории и открытого в них целого ряда объектов жилищ, общественных зданий, фортификационных сооружений. С другой стороны, археологический контекст находок монет позволяет корректировать хронологию некоторых типов самих монет. Для этих целей особенно важны находки монет, которые происходят из разных уровней жизни общественного здания (294), построенного во второй половине 6 в. до н.э. и с перестройками дожившего до середины 5 в. до н.э. Кроме того, большое значение имеют находки монет в слое разрушения древнейших оборонительных сооружений Фанагории (679), которые погибли ок. 480 г. до н.э. К этому же времени относится клад боспорских серебряных монет, спрятанный под стеной дома (205). В целом хронология ранних серебряных монет, найденных на раскопе Верхний город , согласуется с характеристиками этого района города в период поздней архаики ранней классики (примерно до середины 5 в. до н.э.), что позволяет, опираясь на фанагорийские материалы, четко определить рубеж, отделяющий датировки более поздних монетных типов. Публикуемая коллекция представляет собой ценный источник информации о денежном обращении ранней Фанагории, а исследование химического состава металла монет дает возможность подойти к решению вопросов об источниках серебра для ранней боспорской чеканки и атрибуции ряда выпусков. The article is the first publication of the 6th first half of the 5th century B.C. silver coins from excavations at Phanagoria. These numismatic finds are most important for the verification of the date of the Late Archaic and Early Classical layers at the acropolis of Phanagoria and a number of structures discovered there dwellings, public buildings, fortifications. On the other hand, the archaeological context of numismatic finds allows us to verify the chronology of certain types of coins. Most important in this connection are coin finds from different levels of a public building (294) erected in the second half of the 6th century B.C., which existed, after a number of reconstructions, till the middle of the 5th century B.C. There are also important coin finds from the ruined fortifications of Phanagoria (679) destroyed circa 480 B.C. A hoard of Bosporan silver coins concealed under the wall of a dwelling (205) belongs to the same period. In general, the chronology of early silver coins found in the excavation site the Upper City agrees with the features of this area in the Late Archaic and Early Classic times (approximately before 450 B.C.), which allows us to define the border dating later coin types. The collection presented here is a valuable evidence for the currency in early Phanagoria, and the study of the chemical composition of the coin alloy allows us to find out the sources of silver for the Early Bosporos coins and the attribution for a number of issues.

Abstract Two influential explanations of Duterte’s surprising rise and rule are his “penal populist” leadership style and a structural crisis of oligarchic democracy. The populist leadership perspective explains “too little” about the extreme violence of Duterte’s illiberal rule and the vulnerability of the prevailing political order to it. The oligarchic-democracy-in-crisis view, on the other hand, explains “too much” because it is overly generalized and determinist, thus unable to account for what in particular triggered Duterte’s rise despite political stability and economic growth. The article offers a third explanation that integrates a leadership perspective into an oligarchic framework using a “structuration” approach. It focuses on how Duterte’s leadership style enabled him to take advantage of a disjunctive moment in the country’s “liberal reformist” political structure, a distinct subset of oligarchic democracy.

Rats were thyroidectomized-hypophysectomized at weaning and 5 weeks later treated for 36 days with either growth hormone (0.1 or 0.5 mg/day), thyroxine (2.5 µg/day), or both. Growth hormone stimulated growth of all tissues whereas thyroxine accelerated growth of only muscle and certain viscera. The growth response of some tissues to thyroxine was as pronounced as that to growth hormone. Administration of thyroxine increased the response to growth hormone of only the tissues that grew when thyroxine was given alone. Although thyroxine had no effect on the amount of bone protein in growth hormone treated and untreated rats, it had a pronounced effect on the morphology (length and maturation) of bone. The amount of collagen in muscle increased with dosage of growth hormone; thyroxine had no effect on this response. Myosin, on the other hand, increased with growth hormone dosage only in those animals also given thyroxine. Thyroxine given alone increased myosin deposition in muscle but had no effect on collagen in muscle, bone or skin.

The lavas of the Bathgate and Linlithgow Hills occur, as already described, in a series of zones alternating with sedimentary deposits. So far as their field characters are concerned they may be grouped with convenience into two classes: fine-grained, columnar, basaltic types, usually porphyritic with augite and olivine, rarely with felspar, and coarser-grained, doleritic types, usually much decomposed, not evidently porphyritic or porphyritic with olivine alone. The yellow crusts of the compact lavas are minutely vesicular and pumiceous, while steam-cavities are rare in the interior. The doleritic lavas on the other hand are coarsely vesicular and amygdaloidal above and below, and frequently also throughout. The blue basaltic types are relatively very fresh; the doleritic types are frequently entirely decomposed into a whitish, earthy material, with knots of limonite, calcite, and quartz, similar in many respects to the white trap of the coal-fields. Good examples of this mode of weathering may be found in the Riccarton Burn. The differences in texture are probably to be referred not so much to differences in chemical composition as to the effect of variation in the quantity of water vapour contained in the successive flows. The coarse and open structure of the dolerites has evidently also given freer scope to the action of decomposing influences than the more compact structure of the basalts. Both types are much veined by such secondary minerals as calcite, siderite, limonite, quartz, chalcedony, and various zeolites. Frequently cavities in the veins, steam-holes in the pumiceous crusts, and even vesicles within the solid rocks, are found filled with brown viscous pitch or black lustrous asphalt. Such occurrences undoubtedly indicate that these rocks have been subjected to some slight extent to post-volcanic pneumatolytic action.

The comparison of modern climatic conditions and soil salinity in subboreal deserts of Middle Asia (Turanian plain) and Central Asia (Gobi deserts) shows that climate has an effect on salinity of hydromorphic soils. From the other hand, the distribution and degree of salinity of automorphic desert soils are predominantly governed by the distribution of salt-bearing rocks inherited from the previous geologic stages and are not related directly to the modern aridity. This fact allows us to state that the global warming will not promote salinization of automorphic soils of arid regions, except for the soils subjected to aeolian salinization. Climate aridification will provoke soil salinization in hydromorphic conditions.

After trying to nurture positive diplomatic relationships among two major economies in the world, a cold war has been converted into a trade war between China and the United States of America. Massive tariffs have been imposed on Chinese imports by Trump administration due to which china stroked back with its tariff policy for American products. Different Chinese companies like Huawei and Haier must face unforeseen circumstances due to trade war. The market for Chinese products seems to shrank post trump policy; on one side, it is a major setback for the Chinese market as an emerging market. On the other hand, it is a golden opportunity for other emerging markets like India, Taiwan, Singapore, South Korea, and the Philippines. US-market is a vast market for Chinese electronics, technology, agriculture, leather, furniture, and many more household products since china entered in the race of globalization. A rise in tariff triggered a trade war, resulting in a decrease in Chinese share in US-market. This trade war has offered a golden opportunity for emerging markets to take over Huawei and Haier's market due to trade barriers and bans on them from the US. This paper will study deep-rooted causes of the US-Sino trade war by examining the impact of a trade war on Huawei technologies and Haier; big Chinese firms dealing worldwide and have a large share in the US-market. The research type will be exploratory, and most of the data is based on secondary data sources. It has been found in this article that the US-Sino trade war is causing losses to both economies on international trade forum. The products from other Asian countries are replacing the Chinese products in the USA. On the other hand, the emerging markets like India, Hong Kong, South Korea, and Taiwan benefit from the absence of Chinese products from the international market. Hence, the winner of the US-Sino trade wars is emerging economies.
