O estudo investigou empresas argentinas para conhecer os determinantes da estrutura de capital em relação às Teorias Trade-Off e Pecking Order. Com abordagem quantitativa utilizou-se de pesquisa bibliográfica, documental, exploratória e explicativa. O período foi de 2007 a 2016 analisando relatórios financeiros de 103 empresas argentinas, extraídos do banco de dados Economática. As ferramentas estatísticas foram: análise descritiva; correlação de Pearson; VIF; regressão de dados em painel (F de Chow; Hausman; LM de Breusch-Pagan). Percebe-se que empresas argentinas têm maiores endividamentos total, curto prazo e oneroso de curto prazo. Possuem altas médias em tangibilidade, retorno do ativo, imposto de renda, economia fiscal e volatilidade do lucro. O endividamento de curto prazo em empresas argentinas foi destaque com poderes explicativos 80,2%. A liquidez corrente foi destaque sendo significante em todos os endividamentos. A tangibilidade não foi significante em endividamentos de longo prazo e nos onerosos de curto e longo prazos em empresas argentinas. Sugerem-se em futuras pesquisas outras variáveis de endividamento e de seus determinantes, além da velocidade de ajuste do endividamento.
Trends In Climate Variables (Temperature And Rainfall) And Local Perceptions Of Climate Change In Lamu, Kenya
Authors: Yvonne Maingey , Ouma Gilbert , Olago Daniel , Opondo Maggie 
Published: October 2020

Community adaptation to the negative impacts of climate change benefits from an analysis of both the trends in climate variables and people’s perception of climate change. This paper contends that members of the local community have observed changes in temperature and rainfall patterns and that these perceptions can be positively correlated with meteorological records. This is particularly useful for remote regions like Lamu whereby access to weather data is spatially and temporally challenged. Linear trend analysis is employed to describe the change in temperature and rainfall in Lamu using monthly data obtained from the Kenya Meteorological Department (KMD) for the period 1974–2014. To determine local perceptions and understanding of the trends, results from a household survey are presented. Significant warming trends have been observed in the study area over the period 1974–2014. This warming is attributed to a rise in maximum temperatures. In contrast to temperature, a clear picture of the rainfall trend has not emerged. Perceptions of the local community closely match the findings on temperature, with majority of the community identifying a rise in temperature over the same period. The findings suggest that the process of validating community perceptions of trends with historical meteorological data analysis can promote adaptation planning that is inclusive and responsive to local experiences.

Published: October 2020

Background:Spontaneous intracranial hypotension (SIH) is an uncommon, benign, and generally self-limiting condition caused by low cerebrospinal fluid (CSF) volume and pressure usually caused by a CSF leak. Patients with SIH have an increased incidence of subdural hematomas (SDH), which may be bilateral and recurrent.Case Description:We report a unique case of a man presenting with SIH and bilateral SDH that were drained with bilateral craniotomies. During drain removal, the patient had an acute neurological deterioration and a CT scan showed SDH recurrence. The patient had two new recurrent SDH afterwards. After the third surgical intervention, the drain was removed in the OR with concomitant subdural saline infusion, there was no recurrence of SDH after that and the patient has had no further complications after a 2-year follow-up.Conclusion:Patients with intracranial hypotension are predisposed to form SDH. In this case, drain removal caused further decrease in intracranial pressure and triggered a new SDH formation, subdural saline irrigation masked atmospheric pressure and prevented this complication from happening again.
Reperfusion Injury (RPI)/White Cord Syndrome (WCS) Due to Cervical Spine Surgery: A Diagnosis of Exclusion
Authors: Epstein Nancy E. 
Published: October 2020

Background:
Following acute cervical spinal cord decompression, a subset of patients may develop acute postoperative paralysis due to Reperfusion Injury (RPI)/White Cord Syndrome (WCS). Pathophysiologically, this occurs due to the immediate restoration of normal blood flow to previously markedly compressed, and under-perfused/ischemic cord tissues. On emergent postoperative MR scans, the classical findings for RPI/ WCS include new or expanded, and focal or diffuse intramedullary hyperintense cord signals consistent with edema/ischemia, swelling, and/or intrinsic hematoma. To confirm RPI/WCS, MR studies must exclude extrinsic cord pathology (e.g. extramedullary hematomas, new/residual compressive disease, new graft/vertebral fracture etc.) that may warrant additional cervical surgery to avoid permanent neurological sequelae.

Methods:
In the English literature (i.e. excluding 2 Japanese studies), 9 patients were identified with postoperative RPI/WCS following cervical surgical procedures. For 7 patients, new acute postoperative neurological deficits were appropriately attributed to MR-documented RPI/WCS syndromes (i.e. hyperintense cord signals). However, for 2 patients who neurologically worsened, MR studies demonstrated residual extrinsic disease (e.g. stenosis and OPLL) warranting additional surgery; therefore, these 2 patients did not meet the criteria for RPI/WCS.

Results:
The diagnosis of RPI/WCS is one of exclusion. It is critical to rule out residual extrinsic cord compression where secondary surgery may improve/resolve neurological deficits.

Conclusions:
Patients with acute postoperative neurological deficits following cervical spine surgery must undergo MR studies to rule out extrinsic cord pathology before being diagnosed with RPI/WCS. Notably, 2 of the 9 cases of RPI/WCS reported in the literature required additional surgery to address stenosis and OPLL, and therefore, did not have the RPI/WCS syndromes.

Published: October 2020

The purpose of research was to determine the optimal method of applying mineral fertilizers with drip irrigation in strawberry plantations and the level of available forms of nitrogen, phosphorus, and potassium in sod-podzolic mediumloam soil. The studies were carried out on strawberries of Honeyoe and Troitskaya varieties, the experiment was two-factor, the replicates were isolated. The determination of NPK in soil and pH were performed according to the generally accepted recommendations for sod-podzolic soils. Weather conditions during the years of research were sufficiently diverse and determined the irrigation rates of plantings. The results showed that the maximum yield of strawberries (13.3 t / ha) is possible with combined fertilization in reserve and with fertigation, but with fertigation, the yield is stable and varies least of all. The highest content of alkaline hydrolysable-nitrogen and plant-available potassium in the average over the years of research was observed in the variant with fertilization in reserve. It has been established that the most optimal way to fertilize strawberries with drip irrigation is a combined application. Drip irrigation accelerates the mineralization of organic nitrogen. Doses of mineral fertilizers should be increased with the age of plantings, while taking into account the level of basic macronutrients in the soil.

Published: October 2020

The article presents tests of natural creeping apple trees and natural dwarfs, carried out in the in the conditions of the Orenburg region. There were from 50 to 100 trees in the experiment in each variant. Vigorous standard plantations were used as control. The aim of the research was to test natural creeping apple trees, natural dwarfs against the background of standard varieties bred in the South Urals (Chelyabinsk), as well as to determine their prospects for intensive horticulture in the extreme conditions of the region. The preservation of plantings for all variants of the experiment for 20 years of research is high and amounted to 92-99 %, their condition was estimated at 4.5-5.0 points. The highest yield was noted for natural dwarfs (457.2 c/ha), the smallest yield was obtained on vigorous standard plantings (control) – 238.7 c/ha. Naturally creeping apple trees in terms of productivity were higher than control by an average of 25 %. Of the naturally creeping varieties, the most productive were the varieties Podsnezhnik (348.3 c/ha), Chudnoe (335.2 c/ha), the least productive were the varieties Plastun and Kovrovoe (255.1 and 262.5 c/ha, respectively). On the natural dwarfs, the most productive variety was the variety Brat Chudnogo (461.2 c/ha). In the control, the most productive varieties were the varieties Symbol (295.9 c/ha) and Nadezhda (270.5 c/ha), less productive were the varieties Pamyat Zhavoronkova and Fevralskoe (208.0 and 224.1 c/ha, respectively). Low-growing plantations, in particular layer and natural varieties of the Urals, are distinguished by their early maturity and, in general, higher productivity per unit area. The highest labor costs are accounted for by natural dwarfs (485.4 person-day/ha) and the lowest in vigorous plantings (317.4 person-day/ha). This has a positive eff ect on the profit and rentability of production.

Published: October 2020

The article presents methods of experimental polyploidy of fruit, berry and ornamental plants. The purpose of this review is to highlight the problems and prospects of polyploidization of plants in the open ground and in vitro culture and the possibility of their application for apple trees. For the purpose of obtaining apple tetraploids as donors of diploid gametes, seed seedlings were treated with a solution of colchicine in concentrations of 0.1-0.4 % for 24 and 48 hours. Colchicine concentrations of 0.3 % and 0.4 % at 48 hours of treatment had a detrimental eff ect on their development. As a result, tetraploids and chimeras were obtained from seeds from free pollination of the varieties Orlik, Svezhest, Kandil Orlovsky, as well as from seeds obtained from crossing the varieties Svezhest×Bolotovskoe, Moskovskoe Оzherel’e×Imrus, Girlyanda×Venyaminovskoe. The optimal concentration of colchicine was 0.1 %. Methods of colchicine treatment have been studied: 1) adding to the nutrient medium, colchicine concentration: 0.01%, 0.02%, exposure time 24h-19 days; 2) applying amitotic solution to the growth point, colchicine concentration: 0.1 %, 0.2 %, exposure time 24h-7 days. To increase the penetration of colchicine through the cell walls, a 0.1 % dimexide solution was used. Studies have shown that high concentrations and prolonged exposure to colchicine reduce the viability of explants.
