Published: August 2022

In this paper, the new energy automobile front-end frame of a factory is taken as the research object, the polypropylene plastic is used to replace the traditional sheet metal material, and the hyper mesh is used to load the front-end frame’s six loading loads, which are the locking limit tension and the cushion impact force, respectively, pedestrian impact strength, condenser support strength, radiator support strength, oil cooler support strength, ensure to achieve certain mechanical properties before production. The maximum warpage deformation is 1.023 mm by mold flow analysis with Moldflow. It does not meet the needs of manufacturers, so it is necessary to optimize the process parameters. We use the mold temperature, melt temperature, holding pressure, injection time, and holding time as test factors, and take the amount of warpage as the optimization goal. Then this paper uses the orthogonal test method to design the test plan and establishes 25 groups of 5-level 5-factor orthogonal tests. Moreover, the effect of the deformation on the warpage is analyzed. These are all to obtain the minimum warpage deformation and find the optimal combination of process parameters. Verification by numerical simulation shows that the warpage is reduced to 0.632 mm. By analyzing the range and variance, the combination of process parameters is optimized, and the warpage is effectively reduced. In the premise of satisfying mechanical properties, plastic instead of steel, to achieve a lightweight design. It provides correct theoretical guidance for setting the actual injection molding process parameters.

Authors: Yan Yu , Al dmour Ayman
Published: August 2022

Deployable antennas, as the core content of national defense technology research at this stage, have the advantages of large flexibility and light weight in practical applications, so this type of antenna can also be called a rigid-flexible hybrid structure. According to the theoretical analysis of the dynamics of flexible multi-body systems, it can be seen that effective control of unfolding antennas is a basic requirement for practical applications. Due to the instability of the specific numerical solution of the static Lagrangian function, it is difficult to completely meet the constraint equation, which is also the main factor affecting the steady development of flexible multibody dynamics. Therefore, in-depth discussion of the numerical calculation method of the static Lagrangian function, obtaining efficient and stable numerical methods from it, and providing effective information for the process control of the deployment of the antenna, is the focus of scientific research scholars at this stage. Based on the understanding of the flexible multi-body dynamics modeling method, this paper systematically analyzes the calculation method of the differential equations, and combines the direct modification method of the constraint violation of the augmentation method to propose the simulation calculation of the model. The final results prove that the dynamics of flexible multi-body systems have a positive effect on the application analysis of deployable antennas.

Authors: Miftode Radu-Stefan , Haba Ana-Maria , Ursaru Andreea-Maria , Petris Antoniu Octavian , Mitu Ovidiu
Published: August 2022

Familial hypercholesterolemia (FH) is a genetic disorder that affects about 1 in 250 people and increases the likelihood of having coronary heart disease at a younger age. We present the case of a 55-year-old patient, known with inferior and anterior myocardial infarction treated by percutaneous coronary intervention and coronary artery bypass grafts, Leriche syndrome, aortic abdominal aneurysm, and bilateral renal stents—pathologies with onset at a young age—who was admitted for fast-paced palpitations, accompanied by increased fatigue. The coronarography did not reveal any acute lesions, but the presence of ventricular tachycardia at admission required the implantation of a cardiac defibrillator. Since the patient presented with early onset severe systemic atherosclerosis, with a lipid profile dominated by hypo-HDL, doubled by an apolipoprotein A1 deficiency, we considered the diagnosis of familial hypercholesterolemia. Due to the high-risk profile, the association between a statin and a PCSK9 inhibitor was initiated at discharge. At the 1-month follow-up control, a significant reduction of LDL-C has been achieved, with a simultaneous increase of HDL-C serum levels.

THE DYNAMICS OF WAQF ASSET MANAGEMENT IN INDONESIA
Authors: Rozihan Rozihan
Published: August 2022

The aims of this study was to determine the effectiveness of waqf management after the enactment of the waqf management law in Indonesia. As we all know that waqf is not only normative worship but also has a social element in it, thus making it one of the keys to the welfare of Muslims. Therefore, the management of waqf property is very important to be known together. This research used normative juridical research that examines the legal provisions of waqf property management in Indonesia and the study of legal instruments in classical fiqh books regarding waqf management. The potential of waqf in Indonesia is very large, for that the Indonesian government must establish a regulation that regulates the procedures for the collection and management of waqf assets as regulated in Act No. 41 of 2004 concerning waqf. The regulation had led to the birth of an independent institution in charge of collecting and managing waqf assets which are called the Indonesian Waqf Board (BWI). Therefore, there is a need for synergy from various parties regarding the collection and management of waqf assets. If so far BWI is an independent institution in charge of managing waqf, so it is necessary to coordinate with the Agrarian Office, waqf asset management institutions operating in the private sector such as the Indonesian Waqf Savings Account or non-governmental organizations (NGOs). This is done with the hope that Indonesia can optimize its waqf assets and the result of waqf can become an instrument that can reduce poverty.

The fraud is one of the things that can be done by someone, from the mild to the most severe level of cheating. Fraud is one of the acts of fraud and fraud committed by certain groups in obtaining personal gain and of course having a fairly large level of loss. This research aims to explain the ideas and theories and characteristics of perpetrators of fraud, how to resolve the law that must be enforced in order to face judicial problems and risks for perpetrators and ways and strategies to overcome fraud that occurs within the scope of banking. This study used a method in literature and library research, namely analysis in the form of discussions related to legal ideas, theories and the occurrence of fraud in the banking law perspective so that conclusions can then be drawn in understanding the extent to which actions based on fraud perpetrators can harm themselves or loss to another person/party. Losses caused by fraud are very large losses and can be widespread in the scope of banking. In addition, the bank really avoids all forms of loss, one of which is reputation risk which greatly affects the quality of the bank because it can give a bad image and influence to the wider community due to cases of fraud or fraud. The fraud prevention strategy is in the form of a systematic form that exists in controlling fraud, in this case management is required to mobilize productivity and quality resources so that the strategy in controlling prevention can continue and provide useful effects in reducing fraud cases.
