Optimal lamination test of ethylene vinyl acetate sheets for solar modules

ABSTRACTSolar power is inexhaustible and has become one of the most appreciated alternative energy choices. In the development stage, solar modules are subjected to relevant reliability tests to ensure a long lifetime and optimal power generation efficiency. After the lamination process, the performance of solar modules is closely related to the degree of crosslinking of ethylene vinyl acetate (EVA) sheets. Traditionally, the degree of crosslinking on EVA sheets is obtained using the chemical extraction method to measure the gel content of these sheets. Motivated by lamination data, this study first constructed a statistical model to describe the relationship between the degree of crosslinking on EVA sheets and lamination time. Next, under the specification limits of the gel content of EVA sheets, the optimal lamination time of solar modules was derived, and the optimal allocation for measuring EVA sheets was addressed. The chemical extraction method is time consuming and leads to high pollution. The latest method is differential scanning calorimetric (DSC), which measures the curing degree of EVA sheets as the degree of crosslinking on these sheets. This study determined the specification limits of the curing degree under the DSC method. An example is presented to elucidate the proposed procedure.

Effects of flash glucose-sensing technology-based continuous glucose monitoring on compliance of patients with type 2 diabetes mellitus: study protocol for a randomized controlled trial

Background and objectives: Multiple insulin injection therapy has been widely used in the intensive treatment of diabetes mellitus and enabled more patients to obtain good glycemic control. Intensive insulin treatment such as multiple insulin injection every day had been proven to have effects on the protection of islet and delay the onset of diabetic complications. However, during the insulin intensive therapy, severe hypoglycemia must be avoided by intensive glucose monitoring because it can increase the risks of stroke and cardiovascular disease. Conventional invasive intensive blood glucose monitoring is limited in clinical practice because it can cause patient pain and inconveniences. Patient's poor compliance in blood glucose monitoring would restrict the application of insulin intensive therapy in patients outside the hospital. The latest method of flash glucose-sensing technology-based continuous glucose monitoring (CGM) made insulin intensive therapy safer and less painful for a patient with diabetes mellitus. However, little is reported on the effects of flash glucose-sensing technology based CGM in patients receiving multiple daily injections of insulin. This study will provide evidence to validate whether flash glucose-sensing technology-based CGM can increase the behavioral self-monitoring and compliance with self-management of a Chinese patient with diabetes mellitus receiving multiple daily injections of insulin compared with conventional invasive blood glucose monitoring. Subjects and methods: This is a prospective, single-center, open-label, randomized controlled trial. Forty patients with type 2 diabetes mellitus who receive multiple daily injections of insulin at the Department of Endocrinology, Northern Jiangsu People's Hospital, Yangzhou University, China between August 2018 and December 2019 are included in this study. These patients are randomly divided to undergo conventional blood glucose monitoring (n = 20) or a flash glucose-sensing technology-based CGM group (n = 20). Patient recruitment began in August 2018 and will end in June 2019. Analysis of primary outcome measure will be completed in June 2019. The study will end in December 2019. Study protocol: 1.0. The protocol was approved by the Medical Ethics Committee of Northern Jiangsu People's Hospital (approval No. 2018045) and is performed in strict accordance with the Declaration of Helsinki formulated by the World Medical Association. All participants provide written informed consent. Outcome measures: The primary outcome measure is the compliance of glycemic monitoring. The secondary outcome measures include the time taken for reaching the goal of glycemic control, HbA1c, self-management scores, the number of hypoglycemia attacks, and Hamilton Anxiety Scale score. Discussion: This study will provide evidence to validate whether flash glucose-sensing technology can increase patient's compliance of intensive insulin treatments, control blood glucose, and improve quality of life. Trial registration: This study was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR1800017456) on July 31, 2018.

Ginger Rhizome Size Performance in Plantlets Production

In crop production, the latest method of rapid propagation of planting materials is the in vitro method. However, the in vivo method has also the potential for rapid propagation and it could be adopted by any farmer. The plantlets are adaptable to varied climatic conditions, therefore the plantlets could be directly transferred to the field. This study aimed to evaluate the performance of the different ginger rhizome sizes in producing plantlets as planting materials and to determine the most profitable size for plantlet production. Result revealed a comparable highest number of plantlets per sett produced in the 125g and 150g rhizomes. However, the smallest size of rhizome at 50g produced the most number of plantlets per kilogram sett. Bigger sizes of seed rhizomes (75g, 100g, 125g, and 150g) were comparably profitable in producing plantlets as planting materials as revealed by ROI ranging from 106.00% to 107.81%.

English Influences in Urban Fabric Patterns of Baghdad City

Appeared in the thirties of the last century and because of the presence of the English and the expansion of the city of Baghdad residential neighborhoods such as (Salhiya,Waziriya, Ayawadiyah, Batawi) in the suburbs of Baghdad carried a modern style that is different from the traditional pattern in the distribution of space .
 The presence of the English has a clear impact on the appearance and changing patterns of the traditional urban fabric in the city of Baghdad, especially those that were established during their presence in the region. Therefore, the research aims to identify the characteristics that characterized the modern style in the urban fabric of the modern Baghdad revival, which was established after the entry of the English, especially the Salhia region. It is also aimed to know the relationship of this pattern to the traditional style of the old neighborhoods revolving, the reasons for this transformation in the pattern, whether cultural, social or economic, etc. and the impact of these modern patterns in the identity of the city and the latest method of preservation and investment . The hypothesis of the research is that there is a gradual shift in the pattern of urban fabric from the traditional to the modern which appeared in some neighborhoods in Baghdad, and that the presence of the English in the region has a clear effect of this transformation. In order to address the research problem of the lack of clarity of knowledge studied and dealt with the transformation in the pattern of urban fabric of some neighborhoods in the city of Baghdad, the effects of the English occupation, the research developed his plan by an analytical study of the chronological sequence of the emergence of the study area and morphological analysis of the factors behind this change, how to diagnose transitions in the schematic pattern of their traditional tissue through their holistic calendar, and the appearance of the architectural style of the Salhia in this architectural form.

Seismic Active Thrust on Rigid Retaining Wall Using Strain Dependent Dynamic Properties

An analytical model is proposed for the evaluation of seismic active thrust on retaining wall resting on sandy soil. Foundation and backfill soil is idealized as Kelvin-Voigt solid. The governing differential equation of vertically propagating shear wave is solved by maintaining the displacement continuity and stress compatibility at the interface between backfill and foundation soil. Nonlinear distribution of accelerations induced in the backfill soil is then used to compute the seismic inertia force. Total seismic active thrust is obtained by solving the force equilibrium equation of the triangular failure wedge. The present method computes the strain-dependent shear-wave velocity and damping ratio of sand from its modulus reduction and damping ratio curves using an iterative scheme. Amplification and deamplification of the input excitations in the foundation soil and backfill soil are compared with results of dynamic centrifuge tests reported in the literature. An increase in the magnitude of seismic active thrust is observed when the retaining wall is situated on sandy soil in place of the rigid stratum, and the percentage increase is 18% in comparison to the latest method available in the literature. The seismic active thrust values for long period input excitations are nearly 13 to 17% higher compared to short-period input excitations. The parametric study reveals that depth of backfill and foundation soil, impedance ratio, amplitude, and frequency of input motion dominate the response of the backfill soil under seismic condition.

Fracture toughness characterization of polymers-based composites using essential work of fracture method

Fracture toughness of polymer-based composites in plane stress condition has been successfully evaluated using latest method namely essential work of fracture (EWF). This method has been extensively performed in order to assess the performance of two parameters in fracture, i.e. essential work of fracture (we) and non-essential work (βwp) ones. The use of EWF method is widespread due to the preparation of uncomplicated specimens, easy examination and easy data processing procedures but accurate in data analysis. This review is focused on the EWF application for the characterization of fracture toughness of polymer-based composites in which the fracture occurs in plane stress state. The EWF testing procedure is in accordance with the recommendations of the ESIS protocol TC-4. Literature reviewed includes all the major areas of testing and simplification of associated data for both quasi-static and dynamic condition. The latter is an EWF application classified by the type of load applied.

A Bayesian hierarchical model for quantitative and qualitative responses

ABSTRACTIn many science and engineering systems both quantitative and qualitative output observations are collected. If modeled separately the important relationship between the two types of responses is ignored. In this article, we propose a Bayesian hierarchical modeling framework to jointly model a continuous and a binary response. Compared with the existing methods, the Bayesian method overcomes two restrictions. First, it solves the problem in which the model size (specifically, the number of parameters to be estimated) exceeds the number of observations for the continuous response. We use one example to show how such a problem can easily occur if the design of the experiment is not proper; all the frequentist approaches would fail in this case. Second, the Bayesian model can provide statistical inference on the estimated parameters and predictions, whereas it is not clear how to obtain inference using the latest method proposed by Deng and Jin (2015), which jointly models the two responses via constrained likelihood. We also develop a Gibbs sampling scheme to generate accurate estimation and prediction for the Bayesian hierarchical model. Both the simulation and the real case study are shown to illustrate the proposed method.

A Mesh-Free Particle Method for Simulation of Mobile-Bed Behavior Induced by Dam Break

The mesh-free particle method is the latest method in the computational fluid dynamics field. It has become well-known due to its application for simulating any kind of interface deformation and fragmentation, including large disturbance on the interface. In this study, the moving particle semi-implicit (MPS) method has been developed for multi-phase to simulate mobile (erodible)-bed under violent flows such as a dam break. In order to develop the MPS method, multi-phase particle interaction models including self-buoyancy and surface tension models were employed. All of the newly adopted particle interaction models were modified by the author. When fluids collide with the soil bed, the erodible bed can be liquefied. In this regard, polyethylene oxide (PEO) solution was used as a mobile bed. The water column captured by the gate collapsed after opening the gate, and it then propagated over a mobile bed. The mobile bed has various thicknesses based on corresponding experiments. Moreover, the dam break on an inclined tank was also simulated to investigate the swash uprush problem. The maximum velocity and height of mixed flows were measured at a certain point, which aligned with the corresponding experiment. All of the simulation results were compared with those obtained from some experimental work.

STUDY OF THE IMPACT OF INCREMENTAL TECHNOLOGY ON MECHANICAL AND TRIBOLOGICAL PROPERTIES OF BIOMATERIALS

The latest method for creating denture replenishment in CAD / CAM systems is Direct Metal Laser Sintering (DMLS) technology. With the use of DMLS, prosthodontics, implant prosthetics, and facial-cranialjaw surgery adapted to individual patient conditions can be realized. The aim is to evaluate the strength, microstructure, and tribological properties of Ti6Al4V and CoCrMo alloys obtained from DMLS technology in the aspect of therapeutic constructions. The conducted tests show that, in the DMLS technology, as compared to milling technology preceded by casting and forging or pressed powder and sintering, for the same percentage composition of elements, the micromechanical properties, microstructural and tribological change. This procedure, from which constructions for various dental applications are obtained, is the new technology preferred for making permanent restorations faced with ceramics, producing intravascular implants, and implants of the temporomandibular joint. It can be an alternative to conventional cast-based methods and CAD / CAM based milling.

Spatial modeling of groundwater quality based on using Schoeller diagram in GIS base: a case study of Khorramabad, Iran

Regulating the water supply for a specified district needs comprehensive quality information about the nearest aquifer. There are many methods to investigate the water quality, but in most cases, they involve time series study and do not consider space dimension. The application of advanced qualitative assessments such as geographical information systems (GIS) could be a reasonable choice. In addition, the classic Schoeller diagram (CSD) is one of the diverse drinking water assessments in which aquifer quality is distinguished according to major ions concentrations. However, the results of this diagram are limited to one point, and there is no possibility of qualitative classification of the surrounding area. Because of this, in this investigation, a new procedure, called the Schoeller-GIS (S-GIS) approach, is presented in order to apply CSD onto a district through GIS tools. For this project, the quality information of 105 wells in the study area (near Khorramabad, Iran) has been collected, and a quality assessment of the aquifer has been conducted based on both classic and novel approaches. Results indicated that, according to the CSD method, all qualitative parameters of the aquifer except Ca and Mg were located within the Good range, whereas the results of S-GIS approach categorized the study area into Good (55%), Permissible (36%), and Moderately suitable (8%). This indicates that the latest method may be more accurate by about 30% which could lead to more efficient management of water resources.

Chirurgie du ptérygion avec greffe de conjonctive fixée par du sang autologue

Pterygium surgery is marked by the possibility of recurrences; one of the techniques which results in the least recurrences is conjunctival autograft. Fixation of the conjunctiva had traditionally been accomplished with sutures. In recent years, conjunctival grafting has also been performed with fibrin glue. Even more recently, with a view towards improving the quality of postoperative results, some surgeons recommend the use of autologous blood. This study aims to evaluate the stability of this latest method of graft fixation, while assessing its postoperative results. After diagnosis of pterygium, the patients underwent pterygium surgery with a conjunctival graft fixated with autologous blood. They were then monitored for one year, at 24h postoperatively, then seven days, 15days, one month 3months, and every 3months thereafter. In totl, 84.21% of the patients demonstrated stable postoperative fixation; 5.26% of patients experienced significant displacement of the graft. After one year of follow-up, 15.79% of patients experienced recurrent pterygium. Recurrences were more frequent in younger patients and in patients with previous recurrence. Pterygium surgery by conjunctival graft fixated with autologous blood is a safe surgery, with results similar to other pterygium surgery techniques with conjunctival autograft. However, this technique has the advantage less irritation, no risk of transmitting infection and lower cost.

Low cost metal matrix composites based on aluminum, magnesium and copper reinforced with fly ash prepared using friction stir processing

Abstract Fly ash (FA) is a cheaper reinforcement which will bring down the production cost of metal matrix composites (MMCs). This paper reports FA reinforced MMCs based on aluminum alloy AA6061, magnesium alloy AZ31 and copper. The composites were synthesized using the novel and latest method friction stir processing (FSP). The microstructure was examined using optical microscopy, scanning electron microscopy (SEM) and electron back scattered diffraction (EBSD). A homogenous distribution of FA particles was observed in all the composites. The severe plastic deformation of the process caused fracture of FA particles. The grains were refined remarkably in the composites due to dynamic recrystallization and pinning effect. The reinforcement of FA particles enhanced the microhardness of the composites. The strengthening mechanisms were discussed.

InfAcrOnt: calculating cross-ontology term similarities using information flow by a random walk

BackgroundSince the establishment of the first biomedical ontology Gene Ontology (GO), the number of biomedical ontology has increased dramatically. Nowadays over 300 ontologies have been built including extensively used Disease Ontology (DO) and Human Phenotype Ontology (HPO). Because of the advantage of identifying novel relationships between terms, calculating similarity between ontology terms is one of the major tasks in this research area. Though similarities between terms within each ontology have been studied with in silico methods, term similarities across different ontologies were not investigated as deeply. The latest method took advantage of gene functional interaction network (GFIN) to explore such inter-ontology similarities of terms. However, it only used gene interactions and failed to make full use of the connectivity among gene nodes of the network. In addition, all existent methods are particularly designed for GO and their performances on the extended ontology community remain unknown.ResultsWe proposed a method InfAcrOnt to infer similarities between terms across ontologies utilizing the entire GFIN. InfAcrOnt builds a term-gene-gene network which comprised ontology annotations and GFIN, and acquires similarities between terms across ontologies through modeling the information flow within the network by random walk. In our benchmark experiments on sub-ontologies of GO, InfAcrOnt achieves a high average area under the receiver operating characteristic curve (AUC) (0.9322 and 0.9309) and low standard deviations (1.8746e-6 and 3.0977e-6) in both human and yeast benchmark datasets exhibiting superior performance. Meanwhile, comparisons of InfAcrOnt results and prior knowledge on pair-wise DO-HPO terms and pair-wise DO-GO terms show high correlations.ConclusionsThe experiment results show that InfAcrOnt significantly improves the performance of inferring similarities between terms across ontologies in benchmark set.

Aluminum based Composites by Severe Plastic Deformation Process as New Methods of Manufacturing Technology

Composites a material was developed to replace metal and alloys, because of the properties such as light weight and unique mechanical properties. Processing of aluminum-based composites has been developing by new manufacturing technology, namely severe plastic deformation (SPD), to produce unique of mechanical properties. Some of the methods used are; equal channel angular pressing (ECAP), accumulative roll bonding (ARB) and multi-axial forging (MAF). The results of some of these methods were compared with the latest method of new SPD, namely: repetitive press roll forming (RPRF). Based on grain morphology and mechanical properties, the result of RPRF has superior to another method. The properties produced by SPD technology was varies, the highest of hardness produced by RPRF process was 88 HV10, ECAP produced 65 HV10, MAF was 46 HV10 and ARB reached 50 HV10. While the highest of tensile strength produced by MAF was 237 MPa while the RPRF process just only around 147 MPa, but the ultrafine grains just only produced by RPRF method which is 0.9 μm, compared to other methods: MAF 1.2 μm, ECAP 5.7 μm and ARB is not so far with MAF that is equal to 1.4 μm. The RPRF process can be recommended for the interest of the aluminum-based composite materials processing industry. Because currently some component product by industries have been substituted from metal alloy materials to metal-based composites.
