IRRIGATION PERIODS AND FERTILIZER SPLITTING ON THE ARABIC COFFEE PLANT PRODUCTIVITY 2 ABSTRACT In an experiment carried out in a Coffea arabica L coffee plantation, species Catuaí - Red (IAC 44), cultivated 17 years ago, with spacing of 3.5 m among lines and 0.8 m among plants, the effect of different fertilizer splitting and irrigation periods on the coffee plant productivity was evaluated. The experimental design consisted of 4 blocks, containing 4 random portions (P4 = 36; P3 = 24; P2 = 12 and P1 = 4 fertilizer splitting through fertigation). Each portion was divided into 5 non random sub portions, in which 4 sub portions represented irrigation periods (A - from 06/01 to 09/30; B - from 07/15 to 09/30, C - from 09/01 to 09/30, D - from 01/09 to 30/09 fertilized manually) and a sub portion without irrigation (E) fertilized with conventional fertilizer. The culture productivity (crop 01/02) per kg of processed coffee per hectare underwent variance analysis, through which it was verified that there was only a significant effect for the irrigation period factor, and that treatment “A” presented highest productivity.

A área cultivada atualmente no pólo Petrolina (PE) – Juazeiro (BA) com a cultura é de aproximadamente 5000 ha. O objetivo deste trabalho foi avaliar doses de nitrogênio e potássio aplicados via água de irrigação visando aumentar a produtividade da cultura da bananeira no Submédio São Francisco. O nitrogênio e o potássio foram aplicados via água de irrigação numa freqüência de três vezes por semana ao longo de todo o ciclo fenológico da bananeira, utilizando-se injetores hidráulicos de fertilizantes. A adubação fosfatada foi dividida em duas partes iguais, aplicadas a cada seis meses, durante o ciclo da cultura. Para produção de frutos, peso de cacho e número de frutos por cacho em relação ao nitrogênio, ajustaram-se, pela análise de regressão, equações quadráticas, cuja dose que proporcionou a produtividade máxima (17 t.ha-1) foi de 340 kg.ha-1 de N. Essa dose situa-se no intervalo das doses de N que proporcionaram o melhor teor de sólido solúveis. O potássio influenciou apenas no número de frutos por cacho.

C.NITROGEN AND POTASSIUM DOSES THROUGH FERTIGATION ON BANANA CROP 2 ABSTRACT Banana is one the most consumed fruit worldwide and has been cropped in almost all tropical countries. Nowadays, the cropped area in Petrolina-Juazeiro, Brazil, is about 5,000 ha. The aim of this research was to evaluate levels of nitrogen and potassium applied through water irrigation to improve productivity of banana in the semi-arid region of Brazil. Nitrogen and potassium were applied in the irrigation water three times a week during the crop phenological phases. Phosphate fertilization was fractionated in two parts and applied twice a year. Polynomial regression data analysis on fruit yield, cluster weight and cluster fruit numbers showed a quadratic fit. Nitrogen was effective for both bunch, cluster weight and fruit number and the best rate was 340 kg.ha-1 for maximum yield (17,43 t.ha-1), while potassium influenced only the number of fruits by cluster.

Os protótipos construídos em discos de vidro e de tecido não apresentaram sensibilidade às variações de umidade nos substratos avaliados, provavelmente devido à pequena superfície porosa em contato com o substrato. Por outro lado, as leituras dos sensores construídos em cápsula cerâmica porosa apresentaram alta correlação com as dos tensiômetros, mostrando-se viáveis para o manejo da irrigação em hortaliças do tipo fruto cultivadas em substratos. Adicionalmente, os sensores com cápsula cerâmica não requereram qualquer tipo de manutenção durante o período de avaliação, indicando serem altamente viáveis para o controle da irrigação em substratos.

A.VIABILITY EVALUATION OF IRRIGASÒ SENSORS FOR IRRIGATION SCHEDULING ON VEGETABLE CROPS GROWING ON SUBSTRATES 2 ABSTRACT Three 7-kPa matrix tension sensor prototypes, based on the working principle of IrrigasÒ, were tested to schedule irrigation on coconut fibers and commercial substrates cultivated with bell pepper plants. The sensors made with glass and textiles discs were not sensitive to moisture changes on both substrates, due probably to the small porosity surface in contact with the substrate. On the other hand, the correlation between porous ceramic capsule and tensiometer readings was highly significant. Besides, ceramic type IrrigasÒ did not require any type of maintenance during the evaluation period, an indication of toughness. Thus, the ceramic sensor showed to be highly viable for irrigation scheduling on fruit-type vegetable crops growing on substrates.

Abstract

Lessons Learned
The 5-fluorouracil, docetaxel, and nedaplatin (UDON) regimen was well tolerated and showed promising antitumor activity in terms of both objective response rate and survival for patients with advanced or recurrent esophageal squamous cell carcinoma in the first-line setting. UDON may be an optimal treatment option for patients with advanced esophageal cancer who are unfit for docetaxel, cisplatin, and 5-fluorouracil regimens. The high response rate as well as the rapid and marked tumor shrinkage associated with UDON suggest that further evaluation of this regimen in the neoadjuvant setting is warranted.

Background
A phase II study was performed to evaluate the efficacy and safety of 5-fluorouracil (5-FU), docetaxel, and nedaplatin (UDON) combination therapy for untreated recurrent or metastatic esophageal cancer.

Methods
Patients received intravenous nedaplatin (90 mg/m2) on day 1, docetaxel (35 mg/m2) on days 1 and 15, and 5-fluorouracil (800 mg/m2) on days 1–5 of a 4-week cycle. The primary endpoint was response rate, with secondary endpoints including overall survival (OS), progression-free survival (PFS), dysphagia score, and adverse events.

Results
Between March 2015 and July 2017, 23 patients were enrolled. Of 22 evaluable patients, 16 and 4 individuals experienced a partial response and stable disease, respectively, yielding a response rate of 72.7% (95% confidence interval [CI], 49.8%–89.3%) and disease control rate of 90.9% (95% CI, 70.8%–98.9%). Median OS and PFS were 11.2 months (95% CI, 9.1 months to not reached) and 6.0 months (95% CI, 2.5–10.6 months), respectively. Eleven (64.7%) of the 17 patients with a primary lesion showed amelioration of dysphagia after treatment. Frequent adverse events of grade 3 or 4 included neutropenia (87.0%) and leukopenia (39.1%). Febrile neutropenia was observed in two patients (8.7%).

Conclusion
This phase II study demonstrated promising antitumor activity and good tolerability of UDON.
EVALUATION OF THE MECHANICAL PROPERTIES OF DIFFUSION LAYER IN THE PROCESS OF MICROARC STEEL VANADATION
Authors: Stepanov M. S. , Dombrovskii Yu. M. , Davidyan L. V. 
Published: October 2018

Traditional processes of thermochemical treatment of steel have a longer duration, so there are proposed the new methods of intensification of diffusion saturation with high-energy impacts on the material surface. In the process of micro-arc alloying the steel product is immersed in a container filled with powder of coal, and is heated by passing electric current. In a powder environment, microdischarges are formed, which are concentrated around the product and create an area of gas discharge with the formation of a carbonaceous gas environment, which enables carburizing of steel. The application of coating containing diffusant allows forming coating of a carbide type due to simultaneous carbon diffusion into alloying elements. The influence of micro-arc surface alloying of steel with vanadium on mechanical properties of diffusion coatings is studied, and the primary mechanism of steel hardening at microarc alloying is revealed. Cylindrical samples of 20 steel were used; the source diffusant was a powder of ferrovanadium. Current density on the sample surface was 0.3 A/cm2, total duration of the process was 3 min. The mechanical properties of coatings were evaluated by means of indentation using pyramidal indenter, at loads of 2.5 mN, 20 mN and 100mN. The diffusion layer with thickness of 170 – 180 μm consists of a base with hardness of 8 – 9 GPa, containing mild etching inclusions of up to 5 μm with microhardness of 21 – 25 GPa. The base of the layer represents an α-solid solution of vanadium in iron, and inclusions are carbides of VC0.863 type. By atomic force microscopy it was established, that the surface relief is defined by single, relatively large carbide particles with a size of up to 3 μm, and by plural nano-sized carbide particles, which act as the strengthening phase, providing high microhardness of the coating. By method of indentation of the hardened layer cross section using different loads hardening effect of the carbide particles is proven. Estimation of possible mechanisms of hardening have shown that the greatest contribution to diffusion layer hardening is made by dispersion component significantly increasing the yield stress of α-solid solution of iron in comparison with the initial state, which is 38 times greater than the contribution of solid-solution hardening.

Published: October 2018

Introduction: Lumbar Disk Herniation with Radiculopathy (LDHR) appears to be a large and costly problem. The paradigm regarding the best treatment for LDHR has being between surgery and conservative management. The aim of this study was to compare and summarize evidence regarding the effectiveness of surgery and conservative treatment for individuals with sciatica due to lumbar disc herniation.
Methods: This study reviewed all literatures published on individuals with LDHR, who were managed either via surgery or conservative method. Pain and functional disability were the main outcome measures analyzed. A comprehensive search of PubMed, TRIP, PEDro and CINAHL was conducted from October, 2011 to June 2017. Two independent researchers selected the studies, and extracted the data. Methodological quality was assessed using the PEDro scale. Meta-analysis was carried out where suitable.
Results: Eight studies involving (n=1,507) were included in the review. Meta-analysis was conducted for only 4 studies (n=784). The meta-analysis showed significant benefit for early surgery than conservative care -8.01(95% CI, -9.27 to -6.72) in the short-term effect -0.49 (95% CI, -0.7 to -0.28). However, the result for long-term effect did not show any significant difference between surgery and conservative care 1.60 (95% CI, -6.85 to 10.05).
Conclusion: This current evidence suggest that early surgery for individuals with lumbar disc herniation with radiculopathy is better than conservative care in the short-term without any long-term difference. The results of this review should be interpreted with caution as the populations of the included studies were largely heterogeneous.
