Development of the augmented musculature device.

We developed an Augmented Musculature Device (AMD) that assists the movements of its wearer. It has direct application to aiding military and law enforcement personnel, the neurologically impaired, or those requiring any type of cybernetic assistance. The AMD consists of a collection of artificial muscles, each individually actuated, strategically placed along the surface of the human body. The actuators employed by the AMD are known as 'air muscles' and operate pneumatically. They are commercially available from several vendors and are relatively inexpensive. They have a remarkably high force-to-weight ratio--as high as 400:1 (as compared with 16:1 typical of DC motors). They are flexible and elastic, even when powered, making them ideal for interaction with humans.
Study on the dielectric characteristics of DC XLPE cables

The DC characteristics of XLPE (crosslinked polyethylene) power cables were investigated. Cables with an insulation thickness of 2.5 mm, 9 mm, and 13 mm using either XLPE or conductive-inorganic-filled XLPE (XL-A) were manufactured, and four kinds of breakdown tests (DC, polarity reversal, impulse, and superposing opposite polarity impulse on DC prestress) were performed. A 250 kV, XL-A cable (20 mm thickness) was designed and manufactured using the results. The test results show that the XL-A cable possesses much better DC breakdown characteristics than the XLPE cable and is adequate for use in DC cables. >
Quantum Safety Control System

Range safety control system ends up with the task or test of aircraft when there is an irreparable fault during powered phase. The security and the reliability are vital for safety control system. Inspired by the principle of quantum entanglement, we put forward a theoretical quantum safety control protocol which is based on two-step command transmission. In the two-step protocol, a quantum switch and a classical switch are fixed in the safety control process. Quantum switch and the classical switch are in charge of the transmission of cryptogram command and the transmission of execution command respective. Quantum principle guarantees the absolute security of this protocol. Besides, this is the first quantum safety control system.
Measuring the value of a business incubator through the alumni entrepreneurs

Problem Formulation: The return on invest and value of a business incubator is usually calculated through financial figures from the incubators alumni companies. However, an incubator does not coach companies; it coaches people. Thereby it would be more interesting to measure value of the persons, the alumni entrepreneurs, who went through the incubation program. Purpose: Explore how an incubators value can be measured through the individuals who have gone through the incubation program Methodology: Inductive research approach. Literature review followed by qualitative data collection through interviews and surveys. Development of a measurement system which was partly tested through a case study Conclusion: A good measurement system should measure both financials and non-financials and be closely connected to the goal of the organization. Using the alumni entrepreneurs as starting point for measurements is relevant both according to large amount of literature and empirical evidence. But, what to measure and how to do it is not easy, and impact on total value as well as time and resources available needs to be considered.
Optimal current for minimum thermal noise operation of submicrometer MOS transistors

The wide band noise voltage (equivalent thermal noise voltage at the gate) of a submicron MOSFET, working in saturation, exhibits a minimum value at a certain drain current. This is supported by measurements and theoretical analysis based on a suitable thermal noise model. This macroscopic noise model attributes the thermal noise of the drain current to the superposition of two noise sources originating from two separate regions of the transistor's channel (a gradual channel approximation region and a saturation region). The existence of a minimum of the noise spectral density at an optimum drain current (I/sub opt/), is well proved by measurements and is contradictory to the predictions of the current simulation program with integrated circuit emphasis (SPICE) models. An empirical way for evaluating analytically I/sub opt/ is given. The fact of the existence of a noise minimum for a submicron MOSFET, brings a phenomenological equivalence to the bipolar transistor and GaAs MESFET when they are employed at the first stage of an amplifier.
Design, nonlinear modelling and performances of a biomedical system

The present paper deals with design, modelling and characteristics of a biomedical system. The involved biomedical system is a syringe pump generally used for continuous drug infusion. The syringe pump consists of a linear switched reluctance motor (LSRM) coupled to a syringe plunger. In order to determine the axial force to control the syringe plunger, it was necessary to begin by evaluating the thrust force. For that purpose, an analytical approach is developed to evaluate the different forces and pressures involved. In addition, an experimental bench was conceived to determine the thrust force and validate the analytical model of the syringe. Consequent results constituted the key element for designing and modelling the LSRM with the help of finite element methods (FEM). The final step is reserved to predict the dynamic performances of all the biomedical system with and without saturation.
Subjective Well-Being in Times of Covid-19: Positivity Bias

The present study was aimed at investigating subjective well-being before and during COVID-19 pandemic among Brazilian adults. Brazil was one of the worst affected countries of the world in number of COVID-19 cases and deaths . Adults from the five macro-regions of the country answered an online survey in 2018 (N = 616), in 2020 (N = 379) and in 2021 (N = 845). An additional sample of 75 respondents participated at all three times in the survey. Respondents evaluated their current life satisfaction by a single-item measure with a 11-point scale and 5-item Satisfaction with Life Scale (SWLS) using a 7-point scale. They also evaluated how they felt about their lives now in comparison with a year ago and compared their quality of life against the lives of their parents. No differences were found as a function of the timing of the survey in all but one of the measures taken. There was a clustering of life satisfaction scores at around three-quarters of the measurement scale maximum as has been reported for Western and non-Western countries before the pandemic. Respondents’ positive outlook on life was also evidenced by their personal retrospectives, by the self-comparison to one year ago but most clearly by comparison to parents' lives. Our findings showed that they compared themselves to their parents in a way to feel better about themselves. This positivity trend may be an adaptive characteristic of human nature that helps people recover from the slings and arrows of lived experiences.
Interdisciplinary business education: curriculum through collaboration

Purpose – A modern business graduate is expected to have strong disciplinary skills as well as the soft skills of communication and team work. However today's business graduate needs to be more than the traditional “I‐shaped” graduate of the past and more of the “T‐shaped” graduate employers are looking for. Many undergraduate business degrees profess to offer integration of the curriculum but on investigation this occurs mainly through a capstone subject at the end of the degree. Today's business graduates need a more integrated approach to their learning. This paper aims to outline the transformation of a traditional business curriculum to one that is inter‐disciplinary, outlining the necessary steps and conditions including the most challenging – faculty buy in.Design/methodology/approach – The review of the Bachelor of Business degree at University of Technology Sydney (UTS) provided an opportunity to explore the option to embrace an integrated curriculum. The authors outline how the review was shaped.
Design and fabrication of a composite-antenna-structure for broadband frequency with microwave absorber

Here we design, fabricate, and study a composite-antenna-structure (CAS) with excellent electrical and mechanical properties. The CAS, consisting of a glass/epoxy face sheet and a honeycomb core, acts as a basic mechanical structure in which a spiral type antenna is embedded. To increase the signal intensity, a carbon fiber plate is used as the bottom sheet. This reflector interrupts radiation, causing the wave from the antenna source to flow to the end of the arms without sufficient radiation. To overcome this problem, a microwave absorber is used for unwanted radiation to reduce the effect of the reflector. We measured the antenna performance by the return loss, axial ratio, gain, and radiation pattern. The structure showed a bandwidth of 0.5–2 GHz and a gain of 5–9 dBi, with circular polarization characteristics and a reflection loss below −10 dB within the desired frequency band.

Does a higher minimum wage accelerate labour division in agricultural production? Evidence from the main rice-planting area in China

Abstract Agricultural production outsourcing, a new means of agricultural production, can optimise the allocation of resources, reduce agricultural production costs, and improve agricultural productivity. However, farmers' outsourcing behaviours are strongly interfered with by many factors such as economics, technology and institutions. Using a farmer-level data set from 2014 to 2018 in China, we examine the effects of the minimum wage increase on rice farmers' production outsourcing behaviours. Our study relies on a Logit regression framework and uses the control function (C.F.) approach to address potential endogeneity concerns. Results show that the minimum wage increase significantly reduces the probability of farmers conducting production outsourcing. We also examine the heterogeneous effects of the minimum wage increase, and find that compared with other outsourcing services, the adverse effects on harvesting outsourcing are the strongest; the negative effects on production outsourcing are stronger for rice farmers with higher education. Our results provide new insights into understanding how labour regulation affects labour division in agricultural production.

On-chip Integration Of High-voltage Generator Circuits For An Electrostatic Micromotor

This paper presents a high-voltage generator circuit as power supply for an electrostatic micromotor with process integration based on a standard 2/spl mu/m CMOS technology. This voltage multiplier circuit utilizes n-type wells in a standard 2/spl mu/m CMOS process as a vital innovation to achieve electrically isolated and floated diodes. This design secures a high-voltage output limited only by the breakdown voltage of n-well to p-substrate pn junctions. For the process we used, the power supply can provide /spl equiv/50V output by inputting 5V dc power and two non-overlapping 0/5V clock signals.
The dangers of irreversibility in an age of increased uncertainty: revisiting plasticity in invertebrates

Plasticity in traits in response to environmental conditions can increase fitness, expanding the range of environments within which a genotype can generate viable and productive phenotypes, and therefore when and where populations can persist and diversify in ecological space. Adaptive forms of plasticity in invertebrates are diverse, ranging from polyphenism and diapause to behavioural thermoregulation and optimal foraging. Local patterns of environmental variation and developmental constraints will dictate which of these forms evolves. Here we review the core idea that the use of narrow developmental windows by invertebrates to attain specific types of phenotypic changes reduces their reversibility, while increasing their magnitude. These tradeoffs dictate the costs and effectiveness of plasticity in buffering environmental variation. In particular, plastic responses to narrow developmental or environmental windows increase fitness costs when predicted environmental challenges do not materialise, or when the environment changes in unpredictable ways. We then explore the converse idea that increasing trait reversibility depends on extending the period for which genotypes are sensitive to the environment, but also narrows the range of plastic phenotypes that can be generated. Considering these findings together, we would expect that the costs, benefits and constraints of reversible versus irreversible plasticity affect the rate and magnitude of adaptive responses to rapidly changing and novel environments. However, such predictions have rarely been tested or included in theoretical models. Identifying this knowledge gap leads us to propose new research directions to provide a deeper understanding of the evolution of plasticity in invertebrates and other organisms. We illustrate these possible directions through examples of Drosophila adapting to thermal stress.
Standardization of anti-arthritic herbo-mineral preparation

Rasa Bhasma is a multi-ingredient herbo-mineral or herbo-metallic formulation used in the treatment of rheumatoid arthritis. The quality of prepared Rasa Bhasma depends on the quality of raw material and standard manufacturing practice. Standardization techniques help in ensuring the safety and efficacy of the product. Hence the prepared Rasa Bhasma was subjected to both the traditional and modern standardization techniques. Result of the present study suggest that the prepared Rasa bhasma satisfied the required criteria of traditional standardization techniques and the modern standardization techniques confirmed the presence of metals such as Iron, Copper, Manganese, Zinc, Nickel, Cobalt, Arsenic, Cadmium, Lead and Mercury in the prescribed pharmacopeial limit. Infrared spectra analysis confirmed the absence of organic compounds. Hence the quality of the prepared Rasa Bhasma was established using traditional and modern standardization techniques.
The Output Current Controller of a Single-phase Grid-connected PV Inverter in Discrete Fourier Transform

The output current of grid-connected PV inverters should not excess harmonic contents. Also, because they are driven connected with grid, the reliability of electric power’s quality should be secured. But, the current controllers of the grid-connected PV inverter decrease the electric power’s quality due to not considering the harmonic contents of the output current. This paper proposed the current controllers of the grid-connected PV inverters to supplement the decrease of the electric power’s quality because of the harmonic contents of the electric power’s quality and the harmonic contents of the output current. The proposed current controllers controlled the harmonic contents of the output current by controlling gains of the current controllers in consideration of the harmonic contents of the output current. As a result, when total harmonic distributions of the grid voltage were 0.4% and 4.1%, the excellence of the proposed current controllers was shown through the experience, by obtaining excellent results of being controlled low as the total harmonic distributions of the output current were 0.756% and 0.78% respectively.
Marketing Communication Tool on Consumer Buying Behaviour in Selected Supermarkets in Nairobi City County, Kenya

Consumer purchasing habits have remained a challenge for marketers to grasp, and studies have suggested that the construct can be best grasped through marketing communication stimulus that is planned and implemented in the organization. However, empirical research into consumer purchasing behavior in retail supermarkets has been limited and anecdotal, particularly in Kenya, where several stores have gone bankrupt and others are trying to stay afloat. In light of this, the purpose of this study was to look at how marketing communication tools affect consumer purchasing behavior in selected supermarkets within Nairobi City County, Kenya. The tools in marketing communication adopted included; sales promotion, personal selling, direct and digital marketing. Descriptive together with the explanatory research design were applied. Customers were the study's population, with a sample size of 370 customers established using the Yamane method. The respondents for the study were chosen using the convenience sample method. Questionnaire were used in obtaining the study’s primary data. The instruments’ validity and reliability were evaluated to identify the acceptability and adequacy of the research items. The collected information was analyzed utilizing descriptive and inferential analytical methods. The data was analyzed using both descriptive and inferential statistical methods. At the 0.05 level of significance, the multiple regression approach was employed to examine the significant influence of the hypotheses formulated in this study. Research results have shown that in a sample of Nairobi City County supermarkets, consumer purchasing behavior has been significantly influenced by the integrated development of advertising communication technologies. Personal sales, direct marketing, and digital marketing, according to the findings, have had a substantial impact on consumer shopping behavior at selected supermarkets in Nairobi City County, Kenya. Advertising and sales promotions, on the other hand, were shown to have no effect on consumer behavior in a few supermarkets. Although the lack of a link between advertising and sales promotion and consumer buying behavior is indicated by the findings of insignificant effects, marketing firms may still need to focus their efforts on increasing advertisements and promotion in sales as instruments in attracting customers' desires on what is offered in the market. It is recommended that Kenyan supermarket managers use the findings to better understand people's perceptions of market offerings and information exchange on what defines public behavior.

RAFTING SCREWS VERSUS BONE GRAFTS IN DEPRESSED TIBIAL PLATEAU FRACTURES

Background: Tibial plateau fractures involve a major weight-bearing joint. They occur due to a combination of axial loading and varus/valgus applied forces leading to articular depression, malalignment and an increased risk of post-traumatic osteoarthritis. Objective: To evaluate the clinical, radiographic and functional results in a cohort of patients who sustained open reduction and internal fixation by rafting screws 3.5- 6.5mm cortical screws. Patients and methods: A total number of 30 cases were included in this study and divided into 2 equel groups: Group (A) and group (B). The demographic data showed sex distribution as 22 males & 8 females with closed lateral tibial plateau fractures (18 type II & 12 type III). As regard to radiological outcome, there was no significant difference between both groups during the period between December 2019 and November 2020 at Al-Hussein University Hospital. Results: Functional and radiological results without using graft were slightly lesser than when graft was used, but it avoided possible donor site complications of the graft, decreased blood loss and minimized operative time. Conclusion: Treating depressed tibial plateau fractures type II and type III with mild or moderate depression (<1.5cm) by open reduction and internal fixation using large set buttress plate and screws or screws alone without using bone graft or bone graft substitute represented a viable option.
