Electron diffraction by vacuum fluctuations
Authors: Di Giulio Valerio , de Abajo F Javier García 
Published: October 2020

Abstract
Vacuum fluctuations are known to produce electron diffraction leading to decoherence and self-interference. These effects have so far been studied as either an extension of the Aharonov–Bohm effect in front of a planar perfect conductor or through path integral analysis. Here, we present a simpler, general, and rigorous derivation based on a direct solution of the quantum electrodynamic aloof interaction between the electron and a material structure in the temporal gauge. Our approach allows us to study dissipative media, for which we show examples of electron wave function shaping due to the interaction with real-metal surfaces. We further present a proof of the relation between the phase associated with vacuum fluctuations and the Aharonov–Bohm effect produced by the image self-interaction that is valid for arbitrary geometries. Besides their fundamental interest, our results could be useful for on-demand patterning of electron beams with potential application in nondestructive nanoscale imaging and spectroscopy.

Published: October 2020

Abstract
This paper discusses the results of the parameters employed sensitivity analysis in the optimization of hip stem prosthesis geometry using topology optimization techniques based on finite element methods. The study was carried out to examine the relationship of finite element parameters, such as mesh size and stress distribution, and topology optimization parameters, such as percent to retain, to the final geometry of the prosthesis stem. Topology optimization was performed using ANSYS software for hip stem prosthesis, a type of Anatomic Medullary Locking, made from titanium alloy. The results obtained from this study indicate that the selection of finite element parameters and topology optimization parameters will have a significant effect on the shape and geometry of the hip stem. The results of this analysis can be the basis for the development of hip stem shape and geometry through topology optimization techniques.

Authors: Mubarak A Z , Razali A , Rizal M , Hambali K R 
Published: October 2020

Abstract
Backpack-type petrol-driven grass trimmers are a widely used grass trimmer. However, the high vibration on its handle causes machine operator to be at risk of “Hand Arm Vibration (HAV)” or vibration exposure on the arms that can damage the nervous system. This research aims to study the effect of suspended handle materials in reducing the vibration on the handle of the backpack-type grass trimmer. There are three types of materials used in this study, they are natural rubber, rubber silicone and foam EVA (Ethylene-vinyl acetate). The material is layered around the handle and then the vibration on the handle is measured. The result shows that foam EVA has better performance in reducing the vibration acceleration rather than natural rubber and rubber silicone.

Published: October 2020

Abstract
Supply chain characteristics in the agricultural industry differ from the industry in general, the structure is more complex and unique according to its agricultural commodities. All of the aspects starting from the upstream are very important to consider because of their dependence on the suitability of the environment and the processes that are carried out on the pre-source. Patchouli oil industry which is mainly located in Aceh Jaya Regency is the object of this study due to the fact it is the largest supplier of patchouli oil in Aceh Province. It is estimated that patchouli oil which is one of the superior local wisdom product is becoming an interesting subject again. This is indicated by several local products that use it as the main raw material. Certainly, this will be difficult to be applied if the supply chain from the upstream to the downstream is not evaluated and upgraded. For this reason, it is necessary to do a mapping process on the vulnerable side, including pre-source, source, make, and deliver. This mapping used the SCOR method version 12.0 and adapted to the make-to-stock industry scheme. The output of this study is a reliable and measurable process system in the patchouli oil industry.

Published: October 2020

Abstract
This study aims to develop an algorithm for filtering the noise in the fast Fourier transform. It requires the determination of the cycles, based on the rain flow counting method. This design was further applied to remove the lower amplitude cycles in a 60-second strain signal. Therefore, the results indicated that the method was able to remove more than 10% of the lower amplitude cycles at a frequency of 45 Hz. The filtered strain signal maintained the fatigue damage by more than 90% and further upheld its original characteristics. This study concluded that the developed algorithm was able to identify and remove the noise contained in the strain signal.

Authors: Usman Husni , Fonna Syarizal , Thalib Sulaiman 
Published: October 2020

Abstract
Milling management in Mining and Mineral Industries should keep on improving liner design based on operating experience, ore types, good design practice, and also additional data from ball trajectory and DEM simulations. The small-scale trials for evaluating different liner shapes would rather provide important basic information to industrial mills. The lifters with the same face angle, but different configurations could provide improvements in energy efficiency and performance. Integrating the wear rates of liners from the actual measurement of the changes in liner profile over milling time and also using laser-based thickness gauging technology would assist in establishing a more efficient liner profile.

Published: October 2020

Abstract
Managing an organisation without strategy is like as being blind in the world of globalisation. An organisation must formulate a new strategy and find out what parts or departments that should be prioritised to be improved more than others. To be able to formulate the new strategy that is adequate to improve employee performance, the company must be able to identify the source of the main problems that could be obstacles in improving employee performance. This paper presents development of hybrid method between Fuzzy Balanced Scorecard (FBSC) and Performance Prism (PP) to analyse performance of a company. This study took place at a multimedia company with big projects mostly from Indonesia and United States. Result of the study showed that the proposed hybrid method could be used to evaluate the company from 4 perspectives that are customer’s satisfaction, finance, internal business process and learning and growth in PP framework. The fuzzy logic was incorporated in an analytical hierarchy process (AHP) to determine weight for every perspective based on experts’ judgement. Result of this study showed that the investigated company has performance score very high that is 9.938, with the lowest score is employee stakeholder factor. With this result, the company would be able to track down the root cause of the problem and an effective strategic plan could be formulated in order to improve employee and overall company performance.

Published: October 2020

Abstract
Water pumping system is an essential machinery for residential usage. Around 150 litres of water are used by a person in India daily for their daily usage. For this reason the water pumping is used regularly. Due to dynamic performance of the pumping unit pump can be operated in both no load and load condition. Though the pumping system was controlled by throttling drive in the early stage but in modern technological advancement time pumps are controlled by variable frequency drives (VFD). VFD provides the pump variable duty requirements with significant energy saving and improved reliability. In every pumping system due to dynamic forces of hydraulic and mechanical component some vibrations are seen but sometimes this vibrations may be excessive which can damage the components of the pump. The excessive vibrations indicate some problems or failures in the system. Power quality issues are one of those problems which are seen during the vibration of the pump motor and induction motor connected with pump. This paper presents the power quality issues in the pump motor in different control method like vvc+ and v/f control method.

Customary wired checking framework gives dependable arrangement in information transmission yet experiences a few restrictions. The utilization of information links likewise builds establishment and upkeep cost. Information links are influenced by the sun pillar and downpour. Checking station should be found sensibly near the observing plant. To conquer these issue Zigbee based remote checking framework is created for web based observing of a lattice associated photovoltaic framework. A PC-based application coordinated with online capacity is planned and executed so as to permit controller of the framework just as simple access of the information over the web. Boundaries like temperature, illumination, PV power yield and framework inverter power yields are checked. To approve the presentation, the framework has been executed on 100Wp network associated photovoltaic framework.

Authors: Himer Sarah El , Ayane Salima Al , Ahaitouf Ali 
Published: October 2020

Abstract
In CPV technology, a focus on keeping low costs has led most recent designs to use concentration ratios of 1000X or higher. For that, many high-concentration photovoltaic systems use refractive Fresnel lenses because it is one of the main transmission-type concentrators. In this work, a solar concentrator system composed from a typical Fresnel lens made of PMMA, with an effective diameter of 350mm and a squared solar cell of 10x10mm is proposed. The design of a Fresnel lens is introduced; we studied and analysed a squared design configurations with multiple tuning of focal lengths, facet spacing and an extended range of wavelengths. The results show that the Fresnel lens is performant in the visible spectrum with facet spacing of 1mm and the focal length between 265 to 350mm. The acceptance angle of the whole system was between 0.6 to 0.8° and the optical efficiency obtained by simulations was between 80 to 90%.

Published: October 2020

Abstract
Network delay refers to the transmission of various data in the network medium through network protocol, such as TCP / IP. If the amount of information is too large and there is no limit at the same time, the excessive network traffic will lead to the slow response of equipment, resulting in network delay. [2] The main causes of network delay are transmission delay, propagation delay, packet switching, queuing, packet drop and processing. [1]Therefore, in order to study the optimization of network delay, the causes of network delay was studied in detail. Some of the methods were deployed to learn the testing network latency, delay measurement algorithm, for example, Cristian’s Algorithm, network analysis by establishing a packet processing model, and TCP BBR algorithm and analyze the optimization of network delay through the simulation of BBR. Finally, by comparing the data before and after optimization, the results of the optimization of the network delay test data by the BBR algorithm are obtained.

Abstract
Elemental photocatalysts are getting the attention of material scientists as a new class of visible light photocatalysts in recent years. Hence it is important to understand and evaluate their phtocatalytic activity for the rationale design and development of new catalysts at low cost. In this regard, we choose commercial red phosphorus as elemental photocatalyst and we evaluate its activity towards the disinfection of E. coli and reduction of Cr (VI) under natural sunlight. The measured bandgap of red phosphorus is 2.0 eV matches with theoretical value and indicates the suitability of the material as photocatalyst under direct sunlight. Moreover, red phosphorus also has optimum valence and conduction band levels for the successful photo-generation of reactive oxygen species (ROS). These photogenerated ROS could help to achieve the disinfection of E. coli in 50 min. In the case of photocatalytic reduction of Cr (VI), 98% of Cr (VI) reduction has been achieved is in 60 min at pH 2. The rate of Cr (VI) reduction decreases with an increase in pH value similar to the reports with other metal oxide photocatalysts.

AbstractThe health benefits and risks of menopausal hormone therapy among women aged 50–59 years are examined in the Women’s Health Initiative randomized, placebo-controlled trials using long-term follow-up data and a parsimonious statistical model that leverages data from older participants to increase precision. These trials enrolled 27,347 healthy postmenopausal women aged 50–79 years at 40 US clinical centers during 1993–1998, including 10,739 post-hysterectomy participants in a trial of conjugated equine estrogens and 16,608 participants with a uterus in the trial of these estrogens plus medroxyprogesterone acetate. Over a (median) 18-year follow-up period (1993–2016), risk for a global index (defined as the earliest of coronary heart disease, invasive breast cancer, stroke, pulmonary embolism, colorectal cancer, endometrial cancer, hip fracture, and all-cause mortality) was reduced with conjugated equine estrogens with a hazard ratio of 0.82 (95% confidence interval: 0.71, 0.95), and with nominally significant reductions for coronary heart disease, breast cancer, hip fracture, and all-cause mortality. Corresponding global index hazard ratio estimates of 1.06 (95% confidence interval: 0.95, 1.19) were nonsignificant for combined estrogens plus progestin, but increased breast cancer risk and reduced endometrial cancer risk were observed. These results, among women 50–59 years of age, substantially agree with the worldwide observational literature, with the exception of breast cancer for estrogens alone.

Abstract

Objective
Cognitive effects in acromegaly patients are poorly understood and the mechanisms involved are still unclear. The aim of this study was to evaluate the cognitive function, depression, and quality of life of acromegaly patients treated with pegvisomant versus somatostatin analogues (SRLs) and to analyze the effect of the different treatments on cognition and possible structural brain changes.

Methods
This cross-sectional study involved 23 acromegaly patients divided into two groups according to treatment modality: One group of 9 patients treated with pegvisomant and another group of 14 patients treated with SRLs. All participants underwent blood analysis, neuropsychological tests, depression tests, quality of life assessment, and 3-Tesla magnetic resonance imaging.

Results
We found no significant differences between groups in the neuropsychological tests, depression or quality of life; nor in the whole-brain cortical thickness. In the SRL group, the volume of the thalamus correlated positively with executive function, a correlation not found in the pegvisomant group. In addition, the pegvisomant group had significantly higher levels of insulin than the SRL group.

Conclusions
In conclusion, in this pilot study, the type of pharmacological treatment in patients with acromegaly and good glycemic control did not influence the cognitive function and cortical brain thickness. However, pegvisomant could play a neuroprotective role on the thalamus that will have to be demonstrated with larger samples in future studies.
