The tomato plant (Lycopersicum esculentum L.) is a perennial, shrubby-like vegetable with high reproductive ability, which behaves like a typical annual crop. The aim of this work was to select suitable tests to assess the quality of different lots of tomato seeds. Six batches of tomato seeds were assessed for parameter values: moisture content, germination, first count, accelerated aging (standard: 40 mL of water;saline solution: 11 g NaCl/100mL of water and saturated saline solution: 40 g NaCl/100mL water) and seedling emergence in soil. Accelerated aging through the use of saturated salt solution for 48 h or 72 h at 41°C resulted in an alternative and efficient way to evaluate the physiological quality of tomato seeds. The standard accelerated aging test was less efficient and exhibited higher moisture variation.

The short circuit is a severe fault that occurs in the stator windings. Therefore, it is very important to diagnose this type of failure in its beginning before it causes unscheduled stop and the machine loss. In this context, the Support Vector Machine (SVM) is a tool of considerable importance for standard classification. From some training data, it can diagnose whether or not there is a short circuit beginning, and which is important for predictive maintenance. This work proposes a technique for early detection of a short circuit between the turns aiming at its implementation in a real plant. The paper shows simulation and experimental results, and validates the proposed technique.

尽管使用数字来量化研究的科学价值过于简单，但整个科学界越来越依赖期刊影响因子（JIF）评价科技期刊。美国西北大学学者amaral及其同事认为JIF自身及应用过程中存在很多问题，他们提出一种全新的期刊排名计划JRS，并通过翔实的数据验证了JRS比JIF排名期刊具有更高的准确性。与JIF不同，JRS采用数学模型来刻画期刊影响力。

自抗菌类涂料在鞋材中应用以来,引起了制造商和消费者的极大兴趣。研究利用壳聚糖固有的抗菌活性和成膜性制备皮革抗菌材料。考虑到皮革鞣制的特殊性,采用不同的涂饰技术,如转鼓浸渍、辊涂和喷涂。结果表明,采用转鼓浸渍的方法效果最佳。进一步研究了转鼓浸渍涂饰方法中壳聚糖的用量、增溶酸剂的类型和浸渍时间,对抗菌剂抗菌能力的影响。由于壳聚糖价格昂贵(成本原因)以及对最终试验结果(采用SEM考察了抗菌能力和成膜效果)的分析,得出最佳方案:壳聚糖用量为1%(w/v),溶剂为甲酸,转鼓浸渍时间为2h。

Orthognathic surgery involves correction of functional and often esthetic disharmonies. The purpose of this case report is topresent the case of a 22 years-old female with class III dentofacial deformity that required orthognathic surgery to treat hermalocclusion and buccal fat pad excision for optimizing soft-tissue facial contour. Treatment planning involved a counterclockwiserotation of the maxilomandibular complex with genioplasty based on digital 3D surgical planning using the Dolphin Imaging 11.7 3DPremium software. Prototyping splints allowed surgical procedures （bilateral sagital mandibular osteotomy associated to a Le fort Iosteotomy） that corrected position of the gnathic bones. In the same surgical procedure, the buccal fat pad was partially removed for asharp cheek contour giving a slimmer appearance to her face. After 5 months, the patient was reassessed and reported no complaintsregarding esthetics or function. This case illustrates that a combination oforthognathic surgery and an esthetic procedure can result in astable and harmonious facial as well as occlusal outcomes.

MCS （mechanical circulatory support） has shown great efficacy in treatment of respiratory mid cardiovascular diseases when conventional therapy is insufficient. The use of ECMO （extracolporeal membrane oxygenation） for the treatment of cardiogenic shock secondary to sepsis is still controversial. Studies have shown that ECMO should be considered as a valuable therapeutic option in cases of refractory cardiovascular dysfunction in severe septic patients, although more studies ale needed to consolidate its efficacy. We report the case of two patients, without previous history of cardiopathy, subjected to temporary MCS, with use of ECMO for the treatment of refractory cardiogenic shock secondary to sepsis.

Background: Neurofibromatosis type 2 (NF2) is a rare syndrome and it is usually presented with bilateral vestibular schwannomas (VS), multiple meningiomas, and other types of tumors associated to peripheral nerves. Hearing loss is one of its leading manifestations, and surgery for removal of the tumor is often required. Cochlear implant (CI) surgery is an option for auditory rehabilitation and long latency auditory potentials (P300) are becoming a very useful tool to assess hearing outcomes. Objective: To verify the presence of P300 waves during auditory and cortical function assessment in a patient submitted to VS removal and CI surgery. Design: Retrospective chart review. Case Report: A 62 years old male patient, presented at the clinic with a bilateral severe to profound hearing loss, worst at the right side. MRI scan revealed bilateral expansive tumor within the internal auditory canal expanding to cerebellopontine angle, suggestive of VS. Tumor was removed at the right side, and CI surgery was indicated for the left ear. P300 tests were performed pre-operatively, at the moment of activation, and 6 months post-operatively. After CI activation, P300 waves appeared, and presented reduced latency and increased amplitude after 6 months of CI use. Conclusion: P300 waves appear to be dependent on the auditory stimulus to be generated, showing that it can be a useful tool to estimate improvement in cortical cognitive function after restoring hearing through CI surgery after VS removal.

There are different methods to determinate leaf area in coffee plants;however, methodologies that allow measurement of leaf area accurately and in nondestructive ways are very important, as they are less economically costly and enable measurements on the same leaf over time, making it possible to describe accurate patterns of growth. The objective of this study was to investigate the applicability of the method to estimate leaf area using linear dimensions of leaves for improved genotypes of Coffea arabica L. and Coffea canephora Pierre ex A. Froehner. The experiment was conducted in two separated competition fields, each one following factorial schemes 10 × 2, with 10 genotypes and 2 methods to obtain the leaf area: measuring linear dimensions, and using equation model (estimated leaf area) and leaf area integrator (real leaf area). The genotypes for both Coffea arabica L. and Coffea canephora Pierre ex A. Froehner have different leaf areas, making it possible to discriminate groups of genotypes for both species using the size of their leaves as classification criteria. Even with the differences between genotypes, the pattern of leaf shape remains similar, confirming the applicability of the method to estimate leaf area using linear dimensions of leaves for improved genotypes, such as the model proposed by Barros, without the occurrence of loss of accuracy for the improved genotypes, for both Arabica and Conilon coffee, studied in this experiment.

Objectives: The overall aim is to propose a general framework to build any kind of interactive digital atlas. It can be used either as pedagogical support to study human anatomy or as a tool to aid health professionals improving the quality of the human resources formation. Methods: To illustrate the use of the proposed methodology was build an atlas of intracranial human anatomy. We used 3D surface rendering techniques to create a brain atlas that would allow us to correlate bi-dimensional MRI images with 3D brain structures. Results: The system was coded in Java and distributed under GNU/GLP license, making it available to use and/or to expand and serve as an educational tool allow medical students to use it to evaluate the special relationships among structures. Conclusions: The characteristics of the obtained Atlas are essential in the Brazilian public health context, where professionals in several different geographical locations (submitted to distinct informatics infrastructure) need to be trained.
