Logging While Drilling Fluid Sampling and Real Time Formation Evaluation, An Approach for a Successful Sampling Operation
Authors: Correa D. , Barbosa A. 
Published: May 2017

Abstract
Operational execution of Fluid Sampling technologies in the logging-while-drilling (LWD) environment compared with Wireline requires a different set up and allows new operational capabilities for LWD. The objective of this paper is to identify what are the jobs operational risks, in order to select the best LWD technologies and operational approach to identify and mitigate these risks while drilling, resulting in the fastest and cleanest reservoir sample. LWD fluid sampling technology brings three new operational capabilities to this type of service: ability to select pad orientation; drilling fluid flow is required to keep the BHA energized and real time (RT) data telemetry and; capability of operating in HAHZ wellbores without additional risk. To take full advantage of these new capabilities, there must be a full understanding of the relationship between wellbore and formation, analyzing subjects such as filtrate invasion profile, borehole stability, sand production, petrophysics and LWD FE. The ability to choose pad direction, coupled with high end technologies, such as NMR and resistivity images generate important capabilities to be evaluated considering formation quality and borehole condition, allowing the selection, not only of the best depth to sample, considering petrophysical properties, but also the optimum pad direction, considering borehole conditions. Images allow the identification of drilling induced fractures, breakout, faults and thin bed, making it possible for RT interpretation for optimum pad direction, avoiding undesired features. Prior geomechanics study help identify issues that might come up during fluid sampling operation, such as breakout, sand production and borehole failure related to bedding plane. Technologies such as acoustic, NMR and images allow RT evaluation of these issues and the ability to select pad orientation and nonstop drilling fluid flowing may result in correcting these issues. Filtrate invasion profile generates complex geometries with lateral displacements and gravitational segregations. Prior study of invasion profile reservoir and drilling fluid properties, thin bed analysis and reservoir/non-reservoir interface analysis must be considered to achieve optimum operational time. This paper presents a technical and operational approach for LWD fluid sampling operations, regarding FE, geomechanics and fluid invasion profiles, which minimizes operational risk and optimizes sampling time.
Agricultural Conservation Planning Framework: 3. Land Use and Field Boundary Database Development and Structure
Authors: Tomer Mark D. , James David E. , Sandoval‐Green Claudette M. J. 
Published: May 2017

Conservation planning information is important for identifying options for watershed water quality improvement and can be developed for use at field, farm, and watershed scales. Translation across scales is a key issue impeding progress at watershed scales because watershed improvement goals must be connected with implementation of farm‐ and field‐level conservation practices to demonstrate success. This is particularly true when examining alternatives for “trap and treat” practices implemented at agricultural‐field edges to control (or influence) water flows through fields, landscapes, and riparian corridors within agricultural watersheds. We propose that database structures used in developing conservation planning information can achieve translation across conservation‐planning scales, and we developed the Agricultural Conservation Planning Framework (ACPF) to enable practical planning applications. The ACPF comprises a planning concept, a database to facilitate field‐level and watershed‐scale analyses, and an ArcGIS toolbox with Python scripts to identify specific options for placement of conservation practices. This paper appends two prior publications and describes the structure of the ACPF database, which contains land use, crop history, and soils information and is available for download for 6091 HUC12 watersheds located across Iowa, Illinois, Minnesota, and parts of Kansas, Missouri, Nebraska, and Wisconsin and comprises information on 2.74 × 106 agricultural fields (available through http://northcentralwater.org/acpf/). Sample results examining land use trends across Iowa and Illinois are presented here to demonstrate potential uses of the database. While designed for use with the ACPF toolbox, users are welcome to use the ACPF watershed data in a variety of planning and modeling approaches.Core Ideas
Water quality improvement must meet watershed goals through farm‐level measures.
Planning data can help better connect farm implementation and watershed outcomes.
We developed a database to help develop watershed plans through farm‐level options.
The database is available for >6000 HUC12 watersheds in the US Midwest.
The PCSK9 revolution and the potential of PCSK9-based therapies to reduce LDL-cholesterol
Authors: Seidah Nabil G 
Published: May 2017

[first paragraph of article]A large number of clinical trials over the last 30 years have firmly consolidated the importance of lowering low density lipoprotein cholesterol (LDLc) in the prevention of cardiovascular diseases (CVD) and its associated devastating sequelae. While healthy diets and exercise are highly recommended to lower LDLc levels, in many individuals with high baseline levels of LDLc, this is not sufficient to bring levels down to recommended target values in order to prevent recurrent coronary heart disease and cardiovascular complications. This is especially true for patients at high risk of premature cardiovascular death and disability, including those with familial hypercholesterolaemia (FH). FH is a very common inherited disease – affecting at least 30 million people worldwide, with an overall incidence of 1:200 globally – of whom ≤ 1% have been diagnosed. The advent of HMG-CoA reductase inhibitors, also known as ‘‘statins’’, and their first application to hypercholesterolemic patients over 30 years ago, has revolutionized the treatment of FH patients and resulted in substantial lowering of LDLc. In addition, cholesterol– lowering drugs, such as ‘‘ezetimibe’’ that blocks cholesterol absorption from the gut by inhibiting the Niemann-Pick C1-like 1 (NPC1L1) transporter, have also been successful and a 7-year IMPROVE-IT trial revealed that a ‘‘simvastatin-ezetimibe’’ combination resulted in an incremental lowering of LDLc levels and a modest 2% improved cardiovascular outcomes.3 Therefore, it became clear that additional treatments are needed to substantially decrease LDLc and efficiently protect against CVD.

Published: May 2017

In order to study the unsteady performance of a two-stage self-priming centrifugal pump, the unsteady numerical calculation in a two-stage self-priming centrifugal pump was performed and energy characteristics experiments and self-priming experiments were carried out. The pressure pulsation and radial force in the pump were then analyzed. The results show that numerical calculation values are close to the experiment values. Head deviation of the pump is less than 3 %, and efficiency deviation of the pump is less than 2 percentage points. Compared with monitoring point P1, the pressure fluctuation coefficient of monitoring point P3 at the design flow rate is reduced by 61 %. Compared with monitoring point P8, the pressure fluctuation coefficient of monitoring point P5 is reduced by 70 %. The radial force on the radial guide-vane is obviously smaller than that on the volute. Under the same flow rate, radial force on the volute of second-stage pump is almost 20 times larger than that on the radial guide-van of first-stage pump.
Analysis and optimization of drum washing machine vibration isolation system based on rigid-flexible virtual prototype model
Authors: Xiao Linjing , Zhang Sen 
Published: May 2017

In order to improve the calculation accuracy of vibration response in drum washing machine isolation system, a new CAE method is proposed for dynamics analysis and parameter optimization according to the rigid-flexible coupling technology of virtual prototype. With the vector loop algorithm, the motion differential equation of the vibration isolation system is solved based on Lagrange method, and the key parameters that affect the vibration response are acquired. In terms of simulation research, the modal neutral file (MNF) of the shell body is established by the software ANSYS for modal analysis, and it is exported into software platform ADAMS/Vibration to establish the rigid-flexible coupling model. Through the coupling model, the kinetic characteristics are calculated in continuous excitation frequency domain (0-20 Hz). The experimental verification is accomplished by LMS Test.Lab device, of which results shows that the rigid-flexible coupling simulation method is definitely accurate and feasible. Meanwhile, 15 “hot spots” of the shell body are obtained from the ADAMS/Durability module, which can provide an important basis for structure design. Then, the spring stiffness and damping coefficient is synthetically optimized by sensitivity analysis method with 9 time’s iterative calculation, which has a great significance for product development.

Os fragmentos de Artápano: introdução e tradução
Authors: Rios Cesar Motta 
Published: May 2017

Artápano é personagem consideravelmente inusitado da tradição judaica, justamente por quase completamente desconhecido e não ser unanimemente considerado judeu. Sua obra, contudo, da qual nos restam somente três trechos, deixa vestígios sobre seu projeto literário e o liga inevitavelmente à história das narrativas bíblicas, uma vez que consiste em uma ampliação (e transformação) criativa dos relatos de Gênesis e Êxodo sobre as vidas de “heróis” hebreus. Esses três trechos são apresentados aqui em uma tradução anotada, que é antecedida por uma introdução, na qual se discutem brevemente questões importantes para uma leitura informada desses fragmentos.
Sobre a metapoesia em Propércio e na poesia erótica romana: o poeta rufião
Authors: Martins Paulo 
Published: May 2017

Este artigo tem a preocupação de mapear a construção das personae poéticas na poesia erótica romana, entre final da República e o início do Principado, a fim de redimensionar alguns aspectos sobre o "jogo poético" que orienta programaticamente esse tipo de poesia entre a realidade e a ficção. Assim observo, de um lado, aspectos denotativos ou referenciais dessas personae poéticas – masculinas e femininas –, resgatando sua uitae modus ou sua maneira de ser, além do ambiente decoroso, adequado a essa forma mentis, a essa maneira de pensar e de agir. De outro lado, procuro revelar como estas mesmas personae devem e podem ser lidas conotativa ou poeticamente, isto é, entendidas como tropos. Dessa forma, se associamos esse aspecto das personagens poéticas àquela imagem referencial ou contextual, não só podemos ter clareza sobre o "jogo poético" a que está sujeita a recepção de poesia erótica do referido período, como também esse mesmo jogo, fronteiriço por excelência, referencia uma leitura metapoética.
A crítica contemporâna a Heráclito
Authors: Cleto Marcelo de Souza 
Published: May 2017

O debate contemporâneo a respeito da importância de Heráclito tem apresentado uma valorização dos elementos antropológicos, contribuindo para a reavaliação da tendência que enfatizava os aspectos cosmológicos e físicos da filosofia pré-socrática, aquela que modulou basicamente a historiografia da filosofia antiga, na qual os elementos da natureza (physis) eram refletidos conforme a conjuntura epistemológica do final do século XIX e início do XX. Dentre a numerosa crítica contemporânea, podem-se destacar, especialmente, os estudos de Voegelin, Snell e Jaeger, que expressam as tensões que ocorreram nos estudos heraclitianos. Considerando esse cenário epistemológico e hermenêutico, além de adotar o reordenamento dos fragmentos efetuado por Charles H. Kahn em detrimento ao de Diels, o presente artigo examina o esforço contemporâneo que busca alcançar nos registros de Éfeso os indícios da antropologia filosófica.
