Published: February 2019

A preocupação com a biodiversidade vem aumentando nas últimas décadas em função das consequências que a sua degradação causa os desafios para preservação ambiental são diversos e envolvem temas complexos como o excesso de poluição, mudanças climáticas, aquecimento global, contaminação das águas, resíduos sólidos, desenvolvimento sustentável, saneamento básico, refugiados ambientais, energia nuclear, lixo químico/tóxico, extinção das espécies e da biodiversidade, escassez de água doce. O Pagamento por Serviços Ambientais (PSA) surge como um instrumento econômico ambiental para minimizar tais conseqüências através do incentivo à conservação ambiental por meio de estímulos, financeiro ou não, a quem promover os serviços ambientais. A criação de Leis sobre PSA faz-se importante para garantir segurança aos envolvidos e incentivar a criação de novos projetos do gênero. Neste trabalho buscaremos fazer um acompanhamento histórico das primeiras iniciativas de políticas de pagamento por serviços ambientais no Brasil e no mundo ate o caminho percorrido para implementação da política estadual de pagamento por serviços ambientais no estado de Pernambuco, com ênfase, nas ferramentas já usadas na proteção e, em seguida, analisando o contexto da política de PSA em Pernambuco, focando no debate legislativo. Após esse panorama, procederemos ao estudo da política de Pagamento por Serviços Ambientais no estado de Pernambuco como ferramenta de proteção florestal, primeiro visando compreender seus conceitos e aplicabilidade, como forrma de melhor vislumbrar sua real chance de sucesso.

Abstract
A novel Fe3O4@Cu/PVA biomaterial as a new adsorbent and bacterial cell immobilized carrier was synthesized in this work. The structure and morphology were characterized by scanning electron microscopy (SEM). Effects of factors on Mn(II)-based autotrophic denitrification were investigated in a moving bed biofilm reactor (MBBR). The results indicate that the highest nitrate removal and Mn(II) oxidation efficiency occurred under the conditions of initial Mn(II) concentration of 80 mg·L−1, hydraulic retention time (HRT) of 10 h and pH 7. Meteorological chromatography analysis showed that N2 was produced as an end-product, and that gas compositions were different depending on the concentration of Mn(II) in the MBBR. The community diversity in the MBBR was markedly influenced by the concentration of Mn(II) and Pseudomonas sp. H-117 played a primary role in the process of nitrate removal and Mn(II) oxidation.
Prediction of the Disordered Regions of Intrinsically Disordered Proteins Based on the Molecular Functions
Authors: Xie WeiXia , Feng Yong E. 
Published: February 2019

Background:
Intrinsically disordered proteins lack a well-defined three dimensional
structure under physiological conditions while possessing the essential biological functions. They
take part in various physiological processes such as signal transduction, transcription and posttranslational
modifications and etc. The disordered regions are the main functional sites for
intrinsically disordered proteins. Therefore, the research of the disordered regions has become a hot
issue.

Objective:
In this paper, our motivation is to analysis of the features of disordered regions with
different molecular functions and predict of different disordered regions using valid features.

Methods:
In this article, according to the different molecular function, we firstly divided
intrinsically disordered proteins into six classes in DisProt database. Then, we extracted four
features using bioinformatics methods, namely, Amino Acid Index (AAIndex), codon frequency
(Codon), three kinds of protein secondary structure compositions (3PSS) and Chemical Shifts
(CSs), and used these features to predict the disordered regions of the different functions by
Support Vector Machine (SVM).

Results:
The best overall accuracy was 99.29% using the chemical shift (CSs) as feature. In feature
fusion, the overall accuracy can reach 88.70% by using CSs+AAIndex as features. The overall
accuracy was up to 86.09% by using CSs+AAIndex+Codon+3PSS as features.

Conclusion:
We predicted and analyzed the disordered regions based on the molecular functions.
The results showed that the prediction performance can be improved by adding chemical shifts and
AAIndex as features, especially chemical shifts. Moreover, the chemical shift was the most
effective feature in the prediction. We hoped that our results will be constructive for the study of
intrinsically disordered proteins.

:Alzheimer's Disease (AD) is a neurodegenerative disorder with an increasing impact on society. Because currently available therapy has only a short-term effect, a huge number of novel compounds are developed every year exploiting knowledge of the various aspects of AD pathophysiology. To better address the pathological complexity of AD, one of the most extensively pursued strategies by medicinal chemists is based on Multi-target-directed Ligands (MTDLs). Donepezil is one of the currently approved drugs for AD therapy acting as an acetylcholinesterase inhibitor. In this review, we have made an extensive literature survey focusing on donepezil-derived MTDL hybrids primarily targeting on different levels cholinesterases and amyloid beta (Aβ) peptide. The targeting includes direct interaction of the compounds with Aβ, AChE-induced Aβ aggregation, inhibition of BACE-1 enzyme, and modulation of biometal balance thus impeding Aβ assembly.

Published: February 2019

Product quality has become a necessary goal for all manufacturers in today’s competitive market. Product defects, not detected, cause financial damages and reputation loss for the manufacturer. These defects can be due to quality of the inputs or misuse of the good quality inputs during the manufacturing process. This is also the case for wooden panel manufacturing where elements are the basic input. It is possible to reduce the loss of the manufacturer by using a method that minimizes the human error in the inspection of the elements. In this study, we, first, identified the quality control problems of the wooden panel manufacturers and basic steps in the automated element quality control. We then developed a prototype for the detection of knots, the most common defects in wooden panels. This prototype, with 80.0% true positive (with knot defect) and 82.0% true negative (without knot defect) rates, performs close to accuracy rates of a quality control inspector. The element image library created during the development of the system made publicly available for use in similar studies. This prototype is expected to be developed to detect other wood defects and to be applied in the wooden panel manufacturing.

Authors: El-Molla Mohamed , Saad Naveen Y , Ezizah Gada S 
Published: February 2019

In this paper a 2D finite element model (SEEP2D) is implemented to study the actual head loss along the sheet piles fixed at the ends of an apron of a heading up structure. Different scenarios for the thickness of the pervious layer under the apron, the length of the apron and the depths of the upstream and downstream sheet piles are studied. Results show that assuming the outer and inner faces of the sheet piles have the same weight for estimating the creep length while designing aprons of hydraulic structures is weak. Design equations for the actual head loss along the outer and inner faces for both the upstream and downstream sheet piles are driven. These equations can be used as a tool in the practical design for aprons of heading up structures formed on pervious soil and provided with upstream and downstream sheet piles at its ends.

Authors: Khan Muhammad A.A. , Sheikh Anwar K 
Published: February 2019

The demands on the productivity and robustness of metal casting processes for high quality components are continuously increasing. Moreover, the financial considerations necessitate meticulous and reliable planning of the entire casting process before it is actually put into practice. A holistic approach to perform cradle to grave analysis of cast products is simulation-based metal casting. This method allows engineers to model, verify, and validate the process followed by its optimization and performance prediction in virtual reality. This paper provides insights on state of the art in simulation-based metal casting with reference to some case studies. Casting simulations software, mathematical models and solution methods, and casting process simulation together with the results obtained are clearly explained. The current practices revealed extensive utilization of simulation packages for defect minimization, yield maximization, and improved quality. The ongoing research on integration of casting simulations with mechanical performance simulations makes it possible to analyze the serviceability of cast parts. The reliability of cast part in service with dynamic loading of varying thermal and mechanical load cycles can be predicted through this integration. However, more rigorous work is needed in this area, particularly by developing the reliability prediction modules embedded in advanced simulation tools.
Numerical Assessment of Electromagnetic Radiated Emissions from an UWB Radiators Located Inside Metallic Enclosures with Small Air-Flow Openings
Authors: Bait-Suwailm Mohammed M , Boudelliou Boudelliou A , Al-Tarhuni Naser 
Published: February 2019

Shielding effectiveness of electronic devices and computing devices is essential at design stages. Devices should pass electromagnetic interference/compatibility tests for certification purposes. In this paper, we investigate the electromagnetic radiation leakage from modern personal computers and mobile electronic devices due to an ultra-wide band source of noise. Openings and slots are always unavoidable in electronic devices, for instance openings in computers for air-flow and heat dissipation. Three different designs of enclosure’s covers with apertures are modeled for this purpose. The three covers cases comprise the use of rectangular arranged circular holes, hexagonal arranged circular holes, and square openings. For comparison purposes, a shielded enclosure with no openings is considered. The shielding effectiveness is numerically assessed here by capturing electric field strength that is modeled using probes located at two different distances, near- and far-away from the metallic enclosure.
