Determination of batch size at a bottleneck machine in manufacturing systems

In manufacturing systems, there often exists a bottleneck machine whose capacity is equal to or less than the market demand. Any idle or waste time at the bottleneck machine directly impacts the output of the entire plant because it results in a loss of throughput. In order to maximize the capacity utilization by less setup losses at the bottleneck machine, the parts are often produced in batches. Traditionally, most batch sizing decisions are made based on the economic order quantity model where setup and inventory holding costs are considered. This paper presents an alternative method to determine batch size at a bottleneck machine. We present a new objective function and cost factors for batch sizing and investigate queuing and throughput models. A linear search algorithm is introduced to find the optimal throughput rate and batch size at the same time. Numerical examples are examined to see how the batching algorithm works.
Comparison of Culturing and Metabarcoding Methods to Describe the Fungal Endophytic Assemblage of Brachypodium rupestre Growing in a Range of Anthropized Disturbance Regimes

Simple Summary The richness (number of species) of the fungi kingdom is estimated at 1.5 million species, but the vast majority remains unknown. Many of them inhabit plants—the so-called fungal endophytes—and may establish different types of interactions with their host plant. Fungal endophytes have been traditionally studied by letting them grow in appropriate culturing media in petri dishes, but novel massive DNA sequencing techniques which do not require a cultivation step (metabarcoding) are gaining ground. Both techniques were applied and compared to characterize the mycobiome of plants of a tall grass (Brachypodium rupestre) growing in high-mountain grasslands with different plant diversity (low and high). The two methods showed similar trends comparing endophyte richness between plant tissue types (root > rhizome > shoot) and between grasslands (low-diversity > high-diversity). However, the metabarcoding identified almost six times more endophyte species than the culturing although the most isolated fungal species via culturing, Omnidemptus graminis, was not recognized via metabarcoding. We conclude that the complementation of both techniques is still the best option to obtain a complete characterization of the fungal endophytic assemblage of the plant species. Abstract Fungal endophytes develop inside plants without visible external signs, and they may confer adaptive advantages to their hosts. Culturing methods have been traditionally used to recognize the fungal endophytic assemblage, but novel metabarcoding techniques are being increasingly applied. This study aims to characterize the fungal endophytic assemblage in shoots, rhizomes and roots of the tall grass Brachypodium rupestre growing in a large area of natural grasslands with a continuum of anthropized disturbance regimes. Seven out of 88 taxa identified via metabarcoding accounted for 81.2% of the reads (Helotiaceae, Lachnum sp. A, Albotricha sp. A, Helotiales A, Agaricales A, Mycena sp. and Mollisiaceae C), revealing a small group of abundant endophytes and a large group of rare species. Although both methods detected the same trends in richness and fungal diversity among the tissues (root > rhizome > shoot) and grasslands (low-diversity > high-diversity grasslands), the metabarcoding tool identified 5.8 times more taxa than the traditional culturing method (15 taxa) but, surprisingly, failed to sequence the most isolated endophyte on plates, Omnidemptus graminis. Since both methods are still subject to important constraints, both are required to obtain a complete characterization of the fungal endophytic assemblage of the plant species.
COVID-19 and changes in Korean consumers' dietary attitudes and behaviors

BACKGROUND/OBJECTIVES The coronavirus disease 2019 (COVID-19) outbreak has dramatically changed nearly every aspect of our lives. Although Dietary lifestyle includes attitudes and behaviors to meet their most basic needs, but few studies have examined the pattern of changes in dietary lifestyle driven by COVID-19. This study explores changes in dietary attitudes and behaviors among Korean consumers after COVID-19. SUBJECTS/METHODS An online survey was conducted with 549 Korean adults aged 20 and older to identify general demographics and changes in dietary attitudes and behaviors. Data were collected from Oct 12 to Oct 18, 2020. Frequency, percentage, and mean values were calculated and a K-means cluster analysis was performed to categorize consumers based on the 5S of dietary attitudes (i.e., savor-oriented, safety-oriented, sustainability-oriented, saving-oriented, and socializing-oriented). RESULTS Findings indicate consumers considered safety, health, and freshness to be most important when choosing groceries and prepared meal such as home meal replacement and delivery food. Among the types of services, a large proportion of consumers increased their delivery and take-out services. Regarding retail channels, the increase in the use of online retailers was remarkable compared to offline retailers. Finally, consumers were classified into four segments based on changes in dietary attitudes: “most influenced,” “seeking safety and sustainability,” “abstaining from savor and socializing,” and “least influenced. ” Each type of consumer exhibited statistically significant differences by sex, age, household composition, presence of disease, and perceived risk of COVID-19. CONCLUSIONS This exploratory study provides initial insights for future research by identifying various aspects of dietary attitudes and behaviors among Korean consumers after COVID-19.
A COMPARISON OF M-ESTIMATION AND S-ESTIMATION ON THE FACTORS AFFECTING IR DHF IN EAST JAVA IN 2017

ABSTRACTRobust regression on M estimation and S estimation is the Ordinary Least Square (OLS) regression on the data outlier. East Java is one of the provinces in Indonesia with a high case fatalitiy rate (1.34%). The raising of Dengue Haemoragic Fever (DHF) in East Java has been influenced by climate, population density, human behavior, and environmental sanitation. This study aimed to compare robust regression research by using M estimation and S estimation on the factors that affect IR DHF. This was done to get the best model regression on the data outlier based on the biggest R2 adjusted and the smallest MSE. This study utitlized observational research with a non-reactive research design using secondary data. The independent variable consisted of population density, healthy behavior, healthy living environment house, and precipitation in East Java in 2017. The dependent variable was incident rate of DHF in 2017. The population included 38 regencies in East Java, while the sample was 35 regencies/cities selected using simple random sampling. The analysis used robust regression on M estimation and S estimation weighting by Tukey’s Bisquare. Robust regression on S estimation was found to be the best robust regression on data outlier with R2 adjusted (0.996) and MSE (0.229). Robust regression on S estimation was = 54.826 + 0.011 (population density) – 0.136 (% healthy behavior) - 0,404 (% healthy house ) - 0,005 (precipitation). Some factors that affect IR DHF can be the main focus for the prevention and control of DHF for the government and society. Keywords: robust regression, outlier, estimation, estimation, DHF
Pressure instabilities in a vaned centrifugal pump

This article reports the acoustic and fluid-dynamical analyses of large-scale instabilities in a vaned centrifugal pump. The unsteady pressure fields at full/part load were measured by dynamic piezoresistive transducers placed at the impeller discharge and on an instrumented diffuser vane. To spectrally characterize the inception and the evolution of the unsteady phenomena, spectral analyses of the pressure signals were carried out both in frequency and time–frequency domains. Numerical analyses were carried out on the same pump with the help of the commercial code CFX. All the computations were performed using the unsteady ‘transient’ model with a time step corresponding to about 1° of the impeller rotation. The turbulence was modelled by the detached eddy simulation model. Numerical pressure signals were compared with the experimental ones to verify the development of the same pressure instabilities. The unsteady numerical flow fields were analysed to study the fluid-dynamical evolution of the instabilities and investigate their origin.
Understanding Sustainable Technology and Human Behavior: Adolescence to Adulthood!

Understanding how technology and humans interact continues to be dominated by the tool-impact view under which only impact assessments can be done after the fact leaving questions of how the process of humans come about with technology in the first-place unanswered. Urgent concerns of unsustainability are attributed to be the consequence of anthropogenic use of technology since the industrial revolution. If technology is seen to expand human capabilities, the fact that the consequences of its use result in unsustainability (identified as technological adolescence) requires clarification. In an attempt to clarify, this article argues for distinguishing abilities from capabilities and defines technology generally to be the context of extension of human abilities to capabilities. Also, if sustainability is an anthropocentric concept, what 'sustainable technology' means, rather than 'sustainable human development' requires clarification. The extension of ability to capability, the definition of technology as a context of such extension and the end goal of free and full realization of human personality indicate at humans becoming capable in using their own embodiment as the tool to realize self- actualization as the eventual capability. Within such a limiting condition, technology and sustainable technology are withdrawn into (being) human being and sustainable human being, indicating that technicity and anthropocentricity are synonymous. This in turn supports the view that humans and technology co-constitute each other in an ongoing process motivating further research in this direction. Problems of unsustainability are those of requirements of various stakeholders (humans) not being met or insufficiently met. A profile of these requirements is generally based on those arising out of human needs that are hierarchical according to Maslow. Design is a process of arriving at specifications, which if implemented meet requirements and thereby, satisfy human needs. However, based on differences in available resources and individual design ability to meet needs progressively people have come to value needs differently. This article juxtaposes Maslow's hierarchy with models of design ability and levels of leverage for systemic intervention to situate problems of unsustainability systemically and identify the requirement and the necessary design ability to design to meet the profile of needs. The journey of the designer in every individual meeting needs progressively up the hierarchy, is claimed as the required transition to sustainability, from 'technological adolescence', to what can be called, 'technological adulthood'.

Diet composition of the Pharaoh Eagle Owl, Bubo ascalaphus (Strigiformes, Strigidae) in a Steppe region of Algeria

Abstract The diet composition of Pharaoh Eagle Owl (Bubo ascalaphus) was investigated in a semiarid area of North-western Algeria. A total of 65 pellets regurgitated by the B. ascalaphus were analysed, 288 food items were composed primarily of mammal remains (4 rodents, 1 bat and insectivore, 93.7%), and 1 bird species (passerine, 6.3%). The most frequent prey among the mammals were rodents (83.3%), which included Mus musculus (59.7%), Meriones shawi (11.1%), Meriones libycus (11.1%) and Jaculus jaculus (1.4%). The rodents were the most important prey items in biomass (91.4%), M. shawi made up to 41.9% of the total biomass. We may conclude that the Pharaoh Eagle Owl relies, in its feeding, very broadly on small mammals, completed by other groups.
Vitamin D Deficiency Is a Potential Risk for Blood Pressure Elevation and the Development of Hypertension

Background and objectives: Hypertension is a global health problem and a major risk factor for cardiovascular diseases. Vitamin D deficiency is closely related to high blood pressure and the development of hypertension. This study investigated the relationship between the vitamin D and blood pressure status in healthy adults, and their 8-year follow-up was added. Materials and Methods: A total of 491 healthy middle-aged participants without any chronic illness, ages 21 to 67 at baseline, were divided into two groups as non-optimal blood pressure (NOBP) and optimal blood pressure (OBP). NOBP group was divided into two subgroups: normal (NBP) and high normal blood pressure (HNBP). Serum 25-hydroxy vitamin D levels were measured with the immunoassay method. 8-year follow-up of the participants was added. Results: The average vitamin D level was detected 32.53 ± 31.50 nmol/L in the OBP group and 24.41 ± 14.40 nmol/L in the NOBP group, and a statistically significant difference was found (p < 0.001). In the subgroup analysis, the mean vitamin D level was detected as 24.69 ± 13.74 and 24.28 ± 14.74 nmol/L in NBP and HNBP, respectively. Together with parathyroid hormone, other metabolic parameters were found to be significantly higher in the NOBP. During a median follow-up of 8 years, higher hypertension development rates were seen in NOBP group (p < 0.001). Conclusions: The low levels of vitamin D were significantly associated with NBP and HNBP. The low levels of vitamin D were also associated with the development of hypertension in an 8-year follow-up.
Inclusive masculinity and Czechia youth

In this, the first investigation of inclusive masculinities among 18- to 19-year-old Czech students, the authors interviewed 19 participants from a rural part of the country. The purpose of this research was to identify attitudes of young, rural, Czech men toward homosexuality and examine for perceived generational difference compared to men who emerged under communism. Results showed evidence of inclusive masculinities for these rural youth based in three principal categories: (1) positive attitudes toward homosexuality; (2) openness to a bromance with a gay male (dependent on gender typicality); and (3) perceived generational differences in gay acceptance compared to their parents’ generation. Overall, results therefore show that young men in this rural part of Czechia are enacting more inclusive forms of masculinity than possible under communist rule.
Life test and electromagnetic shielding performance evaluation of EMI gaskets

MIL-G-83528B, ASTM 4935-89 and JSS 52100 are some of the specifications used in evaluating the performance of EMI/RFI/EMP gaskets. These gaskets are used to maintain the electromagnetic (EM) shielding integrity in shielded enclosures. A number of test methods are being developed and evaluated to measure accurately EM shielding or volume resistivity of the test samples before and after life test. The measurement methods for volume resistivity given in specifications are standard and accurate. Unfortunately, measurement methods for EM shielding has its own quirks and there is a large variation in shielding performance data from method to method for the same type of EMI gaskets. Besides, measurements procedures and the interpretation of test results have their own problems. It is very difficult to get accurately repeatable results using the same EMI gasket not only in various techniques but also in the same technique in the same test conditions and configurations. Therefore, the use of an EMI gasket on the basis of measurement results in a practical application may cause severe interference problems. In this communication, an attempt has been made to critically analyze all available methods for shielding effectiveness (SE) measurement of EMI gaskets. The comparative experimental results of SE for various types of EMI gaskets being tested using the methods given in modified MIL-STD-285 (MIL-G-83528B)/ JSS 52100 and ASTM D-9,12,14 (co-axial holder) are presented in this paper. The error which may arise in the case of conducting plastic or similar materials due to lack of surface contact is highlighted. The requirement for a different type of SE measurement technique for the EMI gaskets is emphasized and suggested.
Small‐size 11‐band LTE/WWAN/WLAN internal mobile phone antenna

This work presents an internal mobile phone antenna occupying a small board space of 600 mm2 on the system circuit board and providing three wide operating bands of at least 698–960, 1710–2690, and 5150–5825 MHz for the 11‐band long term evolution (LTE)/ wireless wide area network (WWAN)/wideband local area network (WLAN) operation.This includes three LTE bands of LTE700/2300/2500, five WWAN bands of GSM850/900/1800/1900/UMTS, and three WLAN 2.4/5.2/5.8 GHz bands. The antenna is a coupled‐fed shorted monopole, with a wide feeding strip in the coupling feed, a long shorting strip closely coupled to the shorted monopole, and a tuning stub connected to the shorting strip. The antenna's three wide operating bands are achieved and controlled by tuning the width of the feeding strip, the gap between the shorting strip and the shorted monopole, and the dimensions of the tuning stub. Operating principle of the proposed antenna is described in detail in this article. Results of the fabricated antenna are presented and discussed. The specific absorption rate results of the antenna with the presence of the user's head and hand are also studied. © 2010 Wiley Periodicals, Inc.

Interest and outcomes of alveolar distraction osteogenesis for dental implant rehabilitation following mandibular reconstruction

Introduction: Alveolar distraction osteogenesis (ADO) is one of vertical bone augmentation technique used to restore the vertical bone discrepancy between the transplanted graft and the residual alveolar bone after mandibular reconstruction. The aim of this article is to present the clinical outcomes of ADO applied to reconstructed mandible for three patients. Observation: Three patients underwent alveolar distraction osteogenesis procedure on mandibula reconstructed by fibula free flap (n = 2) or iliac crest free flap (n = 1). The mean bone height increase was 11 mm. 16 implants have been placed in all patients, with a success rate of 100% and a mean follow-up of 25 months. Two complications occurred without compromising the final outcome of the procedure: one fracture of the basal bone and one bony interference, both during activation phase. Commentaries: ADO can be performed on reconstructed mandible with free flap to restore alveolar height. An acceptable implant-to-crown ratio allows an optimal supported implant prosthesis. The particular antecedent of our patients can lead to uncommon complications such as basal bone fracture, but doesn't seem to compromise implant placement with good success rate. Conclusions: ADO performed on reconstructed mandible allows appropriate dental implant rehabilitation, achieving good esthetics and occlusal outcomes.
Market Orientation: Synthesis and New Theoretical Directions

The research devoted to market orientation has multiplied since the seminal works of Kohli and Jaworski (1990) and of Narver and Slater (1990). These were primarily structured around the question of the relation between market orientation and organizational performance, which was largely resolved with the publication of three meta-analyses (Rodriguez Cano, Carrillat and Jaramillo, 2004; Kirca, Jayachandran and Bearden, 2005; Ellis, 2006). Two questions remain under-explored: that of the definition of the concept, and that of its implementation. In relation to the first topic, this article proposes integrating existing approaches to market orientation, currently few in number. As well as providing a more complete definition and a better structuring of the concept, this approach leads to a better understanding of its links with organizational performance. In terms of the second topic, the article offers an assessment of the existing methods, as a basis for future directions of research.
High-Speed Resistive Switching of TiO2/TiN Nano-Crystalline Thin Film

High-speed resistive switching was observed in a TiO2/TiN nano-crystalline thin film sandwiched between platinum electrodes. A low resistance state was achieved by applying a single negative 2.0-V amplitude 20-ns wide electric pulse, while a high resistance state was achieved by applying a single positive 2.2-V amplitude 30-ns wide electric pulse. So-called forming process, heating bit material by current flow to form conductive filament path before the resistive switching operation was not required. There was an approximately 40,000% increase in resistive change that was repeatedly obtained in the system.
Molecular Rationale of Insect-Microbes Symbiosis—From Insect Behaviour to Mechanism

Insects nurture a panoply of microbial populations that are often obligatory and exist mutually with their hosts. Symbionts not only impact their host fitness but also shape the trajectory of their phenotype. This co-constructed niche successfully evolved long in the past to mark advanced ecological specialization. The resident microbes regulate insect nutrition by controlling their host plant specialization and immunity. It enhances the host fitness and performance by detoxifying toxins secreted by the predators and abstains them. The profound effect of a microbial population on insect physiology and behaviour is exploited to understand the host–microbial system in diverse taxa. Emergent research of insect-associated microbes has revealed their potential to modulate insect brain functions and, ultimately, control their behaviours, including social interactions. The revelation of the gut microbiota–brain axis has now unravelled insects as a cost-effective potential model to study neurodegenerative disorders and behavioural dysfunctions in humans. This article reviewed our knowledge about the insect–microbial system, an exquisite network of interactions operating between insects and microbes, its mechanistic insight that holds intricate multi-organismal systems in harmony, and its future perspectives. The demystification of molecular networks governing insect–microbial symbiosis will reveal the perplexing behaviours of insects that could be utilized in managing insect pests.
