RFID Based Product Identification in a Closed Box

The main aim of this project is to manage inspection efficiently within the stipulated time line with at most accuracy The carton box containing the products with RFID tags is arranged accordingly. The efficient management system is developed to identify and sort out the quantity of products available in the box without unboxing. The box containing the product is placed in the conveyor once the box is placed a sensor senses the box and sends signal thereby switching ON the conveyor. The box then moves in the conveyor crosses the QR code scanner which reads the master data and sends it to the system the box then travels into the inspection chamber which has the two RFID reader antenna which emits signal and capture total number of RFID tags available in the box and similar tags hence sends the captured data to the system. If the total number of products, tags is matched with the master data the box moves to the selection section. In case if there is any mismatch found like different tags, product count with the master data the product is send for rejection during inspection of product if the product count is found to be less than the count mentioned in the master data a special operation is performed known as shake operation . Where the conveyor is moved back and forth continuously and again the product is inspected if it matches the master data it is sent for selection else the product is moved to rejection section by an arm.
Beamformer Design for Physical Layer Security in Dual-Polarized Millimeter Wave Channels

We develop a beamforming scheme to enhance the physical layer security in dual-polarized millimeter wave (mmWave) systems. We aim to compute a transmit beamformer that maximizes the secrecy rate of the desired user. Assuming the transmitter has a statistical distribution of a dominant radio path, we compute a single-polarization beamforming vector that makes directional transmissions at mmWave frequencies more secure. Moreover, we propose a channel sounding scheme to obtain a weight vector that combines the dual-polarized antennas for improving the secrecy rate. Simulation results are presented to verify the secrecy rate performances of the proposed beamforming algorithm.
Metabolic Abnormalities and Metabolic Syndrome among Cameroonian Women: Comparative Study between Pre- and Post-Menopausal Women

The high prevalence of non-communicable diseases is a challenging problem in the Cameroonian population and women are the most affected. The aim of the present study was to determine and compare the prevalence of metabolic abnormalities and metabolic syndrome (MetS) among pre- and post-men- opausal women living in urban areas in Cameroon. A total of 499 women were recruited during a mass health campaign in 2018. Metabolic abnormalities were diagnosed using International Diabetes Federation (IDF) criteria. MetS was defined using IDF criteria with slight modification (total cholesterol used instead of HDL cholesterol). Logistic regression was used to estimate the association between menopausal status and metabolic abnormalities and MetS in age control and non-control models. The prevalence of high waist- to-hip ratio (56.8% vs 36.3%, p < 0.001), elevated fasting blood glucose (glycemia ≥ 100 mg/dL) (38.7% vs 26.9%, p = 0.006); diabetes (14.6% vs 5.7%, p = 0.001); high triglycerides level (29.7% vs 17.1%, p = 0.002); hyperlipidemia (high total cholesterol and or triglycerides levels) (45.0% vs 30.8%, p = 0.002); and elevated blood pressure (67.9% vs 56.1%, p = 0.007) were higher among post-menopausal than pre-menopausal women. The overall prevalence of MetS was 30.1% and post-menopausal women were more affected (33.8% vs 25.0%; p = 0.034). The odds ratio of MetS was 1.888 (95% CI: 1.016 - 3.507) when age was covariate, but was slightly reduced without age control (OR = 1.532; 95% CI: 1.031 - 2.275). Metabolic abnormalities seem to be a major health problem among Cameroonian women and menopausal status increased the risk of developing a cardiovascular event.
Food cooking methods contribute to the reduced vitamin C content of foods prepared in hospitals and care facilities: a systematic review

Recent cases of scurvy within health care have been reported internationally. One potential reason is vitamin C losses associated with food cooking methods. This review systematically synthesised the published literature to determine the extent that vitamin C in food is lost secondary to food cooking methods used in hospitals or care facilities. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and was prospectively registered in the Prospective Register for Systematic Reviews. Searches were run in three databases with no date restrictions, complemented by an internet search and reference checking. Search terms focused on the intervention and outcome. The final review included seven publications including longitudinal studies and comparison to reference standards. All studies identified vitamin C losses between preparation and service resulting from food cooking methods. Quality was rated as positive for four papers and neutral for the remainder of the included library.
Evidence of rapid non-targeted effects of cycloheximide on soil bacteria using 13C-PLFA analysis1

Abstract: Stable isotope probing of phospholipid fatty acids (PLFA-SIP) is useful when studying bacterial contributions to soil processes, and it is an effective way to separate fungal and bacterial activity by linking 13C enrichment to specific PLFAs. Distinguishing bacterial contributions to soil processes often employs selective inhibitors; however, studies demonstrating their efficacy when using PLFA-SIP are less common. Here, we determined the effect of the fungal inhibitor cycloheximide (4.8 mg g−1 dry soil) and the bacterial inhibitor bronopol (0.48 mg g−1 dry soil) on microbial communities white spruce [Picea glauca (Moench) Voss] forest floor by measuring the uptake of 13C-enriched glucose (2 mg g−1 dry soil) in microbial PLFAs. We targeted [13C]glucose uptake by the bacterial community conditioned to a stable soil environment of 23 °C for over 2 wk rather than new bacteria generated from active colony growth caused by glucose addition. Nearly all bacterial PLFAs exhibited pronounced inhibition of 13C enrichment in the presence of bronopol. Limited inhibition of 13C enrichment in the presence of cycloheximide was observed as bacterial PLFA affected by cycloheximide had roughly one third less 13C enrichment than samples emended with [13C]glucose alone. Inhibitory effects only reduced 13C enrichment and did not affect total PLFA concentrations, implying that the inhibitors in the concentrations applied were impeding bacterial activity without causing cell death. Based on this work, we conclude that bronopol is an effective inhibitor for bacteria. Additionally, non-targeted effects of cycloheximide on soil bacteria must be accounted for when it is used in soil incubations.
The histopathological effect of diclofenac potassium on maternal and fetal tissues

Diclofenac (DCF) is one of the most generally utilized non-steroidal antiin lammatory therapies during the world for different diseases curing in post pubertal ladies. Be that as it may, constrained data is accessible with respect to its security during pregnancy and teratogenicity. The present study was done to investigate the histopathological impact of diclofenac potassium (DP) on some vital maternal and fetal tissues, placenta and liver during two different periods of gestation. In this study 30 pregnant rats have been used and divided into 3 groups (ten for each one); group 1 (control), group 2 treated with 15.4 mg/kg of diclofenac potassium during organogenesis period, and group 3 subjected during fetal developmental period with the same dosage. At the 20 gestation day the rats were anesthetized and dissected, histopathological studies on placenta, maternal liver, and fetal liver have been done. Our results revealedmoderate to severe histopathological alternations in all examined tissues like disorganization of tissue architecture, vacuolation, lymphatic in iltration, apoptosis and more changes. There is a harmful effect of the DP on the placenta tissue and also the liver tissue of the fetus, and on this we recommend that you use the DP with caution during pregnancy at the possible lowest effective dose and for the shortest duration.
Suppression of environmental DNA degradation in water samples associated with different storage temperature and period using benzalkonium chloride

Environmental DNA (eDNA) is a useful tool for biological monitoring of a target species by detecting DNA contained in environmental samples. However, the suppression of eDNA degradation after sample collection is a major issue when estimating the presence of a target species. Recently, benzalkonium chloride (BAC) was shown to dramatically suppress the degradation of eDNA in fish species from freshwater environments. However, the effect of this inexpensive reagent has not yet been tested in the other fish and shellfish species. We examined changes in eDNA concentrations for three target species (Corbicula japonica, Lateolabrax japonicus, and Anguilla japonica). eDNA was measured in samples containing added BAC. The effects of storage temperature (25°C, 4°C, and −30°C) and storage periods (periods up to 21 d) were also measured to determine how sample degradation was affected. We observed that BAC addition was effective in suppressing eDNA degradation, and its influence was similar among species but not storage temperatures. The concentrations of eDNA with BAC for all three species did not decrease with storage period, except for L. japonicus at 25°C and 4°C. Our results suggest that BAC affects eDNA degradation universally for a variety of species inhabiting both freshwater and brackish water.
Estimating feral cat (Felis catus) density in a rural to urban gradient using camera trapping

ABSTRACT Control or eradication of feral cats (Felis cattus) is necessary for a number of reasons, including controlling zoonotic diseases and protecting native species in New Zealand. Estimating feral cat density provides vital information about location and logistical effort required for control operations but current methods used to estimate feral cat densities are often labour intensive and invasive, and may not provide appropriate baseline data. We determined the effectiveness of using camera traps to estimate a feral cat population compared with live-capture trapping in a semi-rural park. Camera trapping, with capture–recapture statistical modelling, was used to estimate population density of feral cats as between 1.06 and 1.19 cats/km2 with an individual detection probability of 5.3% per camera/night. Camera trapping (seven individual feral cats identified) was a valuable addition to live trapping of feral cats (four cats live trapped) and provided a cost-effective, non-invasive and potentially more accurate tool for wildlife managers and researchers to measure feral cat densities.
Establishing Professional Intercultural Relations: Chinese Perceptions of Behavioural Success in a Sino-American Exchange Visit

ABSTRACT This article examines the ways in which professionals from different countries handle first encounters when they wish to initiate and establish business/professional relations. The majority of research on business relations in intercultural contexts has so far focused on misunderstandings, face threats, and conflict. There has been comparatively little research into the initiation and establishment of relations from a positive perspective. This article addresses this lacuna by analysing how Chinese delegates built positive relations with American counterparts on a visit to the USA. Drawing on insights from the analysis, it proposes a conceptual framework for future research in this area.
The influence of muscle fiber type on slow component of oxygen uptake kinetics

The purpose of this study was to investigate the influence of muscle fiber type on the slow component of oxygen uptake (VO2) kinetics and electromyographic activity. Twelve sprinters and ten endurance runners participated in the study. They performed two separate treadmill running tests, the first test being conducted to determine the ventilatory threshold and maximal oxygen uptake. The second test consisted of a 6 min running bout at severe exercise intensity. A two-component exponential model was used to fit the VO2 response. Surface electromyographic signals were collected from Vastus lateralis, and processed by wavelet analysis. Sprinters and endurance runners, with their distinct anaerobic and aerobic fitness, showed a substantial difference in VO2 slow component during severe exercise. The sprinters showed a significantly higher VO2 slow component amplitude (A2: 381.0 ± 96.3 mL/min) and a significantly earlier slow component onset (TD2: 118.1 ± 16.1 s) than the endurance runners (A2: 142.2 ± 58.4 mL/min, TD2: 145.9 ± 19.9 s). The electromyographic mean power frequency of the tested muscles increased significantly during the slow component phase. There is a significant correlation between VO2 slow component and electromyographic mean power frequency for endurance runners (r = 0.50, p = 0.003). The combined use of VO2 kinetics modeling and electromyographic measurement provides evidence of the influence of muscle fiber type on slow component of oxygen uptake kinetics during severe intensity exercise.
Quality Control of the Continuous Hot Pressing Process of Medium Density Fiberboard Using Fuzzy Failure Mode and Effects Analysis

In this paper, a fuzzy failure mode and effects analysis (FMEA) method is proposed by combining fault theory and a failure analysis method. The method addresses the problem of board thickness control failure and the problem of thickness deviation defect blanking, which can occur during continuous hot pressing (CHP) process, which is one of the most important processes in the production of medium-density fiberboard (MDF). The method combines the fault analysis with the Hamming code method and using the Hamming code to calculate and represent the cylinder array of the continuous hot-pressed thickness control execution unit to analyze and process the potential fixed thickness failure modes in MDF hot press production, and then summarizes the decision rules for controlling the board thickness and the level of sheet deviation. By combining the fuzzy FMEA method of the Hamming code and the logical OR operation of the experimental analysis, the method of thickness deviation and recognition control fault information for the CHP of MDF, which is proposed in this paper, permits the increase of the number of error levels, which makes optimization for controller more convenient and improves the efficiency to recognize errors.
The Effect of Student Work Group Emotional Intelligence on Individual Task Performance in Teams

Background: The development of employability skills is a concern of educational institutions, which must introduce experiential learning scenarios for undergraduate students. Purpose: This study is aimed at testing the relationship between emotional intelligence and individual task performance in teams, during a recruiting activity for an experiential learning program. Methodology/Approach: Self-reported and third rater’s measures were used to assess both variables as part of the selection process of participants on an experiential learning program focused on engineering competitions. Exploratory structural equation modeling was used for data analysis. Findings/Conclusions: Results show partial support of the hypothesis by revealing a significant but apparently counterintuitive relationship. Implications: The study reveals the measurement of employability skills as a challenge and a necessity. For employers, it reinforces that teamwork, socialization, and daily organizational endeavors require the appropriate soft skills to obtain good performance levels.
Evidence for the evolution of thermal tolerance, but not desiccation tolerance, in response to hotter, drier city conditions in a cosmopolitan, terrestrial isopod

Cities are often hotter and drier compared with nearby undeveloped areas, but how organisms respond to these multifarious stressors associated with urban heat islands is largely unknown. Terrestrial isopods are especially susceptible to temperature and aridity stress as they have retained highly permeable gills from their aquatic ancestors. We performed a two temperature common garden experiment with urban and rural populations of the terrestrial isopod, Oniscus asellus, to uncover evidence for plastic and evolutionary responses to urban heat islands. We focused on physiological tolerance traits including tolerance of heat, cold, and desiccation. We also examined body size responses to urban heat islands, as size can modulate physiological tolerances. We found that different mechanisms underlie responses to urban heat islands. While evidence suggests urban isopods may have evolved higher heat tolerance, urban and rural isopods had statistically indistinguishable cold and desiccation tolerances. In both populations, plasticity to warmer rearing temperature diminished cold tolerance. Although field‐collected urban and rural isopods were the same size, rearing temperature positively affected body size. Finally, larger size improved desiccation tolerance, which itself was influenced by rearing temperature. Our study demonstrates how multifarious changes associated with urban heat islands will not necessarily contribute to contemporary evolution in each of the corresponding physiological traits.
‘Do digital technologies matter? How hyperlocal media is re-configuring the media landscape of a Russian province’

The increase of internet penetration across Russia has reduced entry barriers for individuals and companies who want to report locally. New digital technologies have given rise to many semi-professional local media projects, so-called ‘hyperlocal media’ (Metzgar et al., 2011; Tenor, 2018), created on various online platforms and social networking sites. Websites, blogs, and social media groups (the so-called ‘pabliki’ in Russian) on the popular social networking site VKontakte have opened up new access routes to local news, both for ordinary citizens and the authorities, but have also become a challenge for traditional local media. This article investigates how the media landscape changes in response to digital technologies in a provincial town of nearly 40,000 in the European part of Russia. More specifically, the article investigates how professional journalists from traditional media and practitioners from hyperlocal media sites understand the influence of digital technologies on the aims and work practices of media in a Russian province. The study is based on in-depth interviews with the editors of traditional local media (e.g. print newspapers) and owners of new hyperlocal media initiatives. The research explores different approaches to the ways in which two groups of media actors understand and make use of the internet and digital technologies. However, within peculiar Russian media model, these differences have led to collaborative rather than competitive relations between the two groups.
Gasoline to Diesel Consumption Ratio: A New Socioeconomic Indicator of Carbon Dioxide Emissions in China

In recent years, gross domestic product (GDP) has grown rapidly in China, but the growth rate of carbon dioxide (CO2) emissions has begun to decline. Some scholars have put forward the environmental Kuznets curve (EKC) hypothesis for CO2 emissions in China. This paper utilized the panel data of 30 provinces in China from 1997 to 2016 to verify the EKC hypothesis. To explore the real reasons behind the EKC, the index gasoline to diesel consumption ratio (GDCR) was introduced in this paper. The regression results showed that CO2 emissions and GDP form an inverted U-shaped curve. This means that the EKC hypothesis holds. The regression results also showed that a 1% GDCR increase was coupled with a 0.118186% or 0.114056% CO2 emission decrease with the panel fully modified ordinary least squares or panel dynamic ordinary least squares method, respectively. This means that CO2 emissions negatively correlate with GDCR. From the discussion of this paper, the growth rate reduction of CO2 emissions is caused by the economic transition in China. As changes of GDCR can, from a special perspective, reflect the economic transition, and as GDCR is negatively correlated with CO2 emissions, GDCR can sometimes be used as a new socioeconomic indicator of carbon dioxide emissions in China.
Comparison of Chemotherapeutic Activities of Rhodamine-Based GUMBOS and NanoGUMBOS

Rhodamine derivatives have been widely investigated for their mitochondrial targeting and chemotherapeutic properties that result from their lipophilic cationic structures. In previous research, we have found that conversion of Rhodamine 6G into nanoGUMBOS, i.e., nanomaterials derived from a group of uniform materials based on organic salts (GUMBOS), led to selective chemotherapeutic toxicity for cancer cells over normal cells. Herein, we investigate the chemotherapeutic activity of GUMBOS derived from four different rhodamine derivatives, two bearing an ester group, i.e., Rhodamine 123 (R123) and SNAFR-5, and two bearing a carboxylic acid group, i.e., rhodamine 110 (R110) and rhodamine B (RB). In this study, we evaluate (1) relative hydrophobicity via octanol–water partition coefficients, (2) cytotoxicity, and (3) cellular uptake in order to evaluate possible structure–activity relationships between these different compounds. Intriguingly, we found that while GUMBOS derived from R123 and SNAFR-5 formed nanoGUMBOS in aqueous medium, no distinct nanoparticles are observed for RB and R110 GUMBOS. Further investigation revealed that the relatively high water solubility of R110 and RB GUMBOS hinders nanoparticle formation. Subsequently, while R123 and SNAFR-5 displayed selective chemotherapeutic toxicity similar to that of previously investigated R6G nanoGUMBOS, the R110 and RB GUMBOS were lacking in this property. Additionally, the chemotherapeutic toxicities of R123 and SNAFR-5 nanoGUMBOS were also significantly greater than R110 and RB GUMBOS. Observed results were consistent with decreased cellular uptake of R110 and RB as compared to R123 and SNAFR-5 compounds. Moreover, these results are also consistent with previous observations that suggest that nanoparticle formation is critical to the observed selective chemotherapeutic properties as well as the chemotherapeutic efficacy of rhodamine nanoGUMBOS.
