Measurement of trace gas concentration with pressure-calibration method based on wavelength modulation absorption spectrometry

A theoretical description of pressure-calibration method based on wavelength modulation absorption spectrometry (WMAS) with second harmonic detection for precise measurements of trace gas concentration will be present in this paper. The method can obtain the consistent relation between gas concentration and second harmonic signal in pressure changes. The signal is monotonic function when gas concentration as metrics and it becomes a complete linear function when density of particles number as metrics. It not only allows complying with traditional WMAS technique without any calibration methods, but also applying to various environment of pressure variations. Typical applications like environmental monitoring and remote sensing can be used this method to calibrated measurement results. In addition, the method is not restricted to situations with typical applications. Furthermore, it can also easily be adapted to various gas concentration detection under pressure changes. The pressure-calibration method can be useful for gas concentration measurements so that assist to ensure the accuracy of data in research.
Drug-induced liver injury secondary to biologic medications in inflammatory bowel disease: 
meta-analysis and systematic review

We aimed to study the prevalence of in adult Material and methods: With the guidelines described by PRISMA-P, a detailed search strategy for each electronic database was developed based on the one used for PubMed, Medline, and Embase. We included prospective and retrospective randomized controlled trials (RCTs) that assessed the efficacy and hepatotoxicity of biologics in IBD patients. Hepatotoxicity was defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) > 2× upper limit of normal or cholestasis. We used Review Manager 5 (RevMan5) to analyse the data. We calculated the odds ratio (OR) with a 95% confidence interval (CI). We assessed heterogeneity using the c 2 test and the I 2 statistic. Results: We identified 862 records in total. After we had removed duplicates 564 records were left for review. Four studies did not report on how participants were randomized to treatment groups or how allocation concealment was achieved; we rated these studies at unclear risk of bias for these domains. There was no presence of any heterogeneity among studies ( c 2 = 2.21, d f = 6, p = 0.90, and I 2 = 0%), when all seven studies were involved for analysis. Our meta-analysis was conducted on the fixed effects model, with 0.770, 95% CI (–0.630, 0.957), and p = 0.02. Hepatotoxicity was not related to any tumor necrosis factor α antagonist. Thiopurine-induced liver injury occurred more frequently within the first months of treatment, 50% of cases within the first 3 months. However, risk of hepatotoxicity above the third quartile (6-MMPR > 5,300) was 5 times that below the third quartile (11.4% vs. 2.3%, p < 0.05). Conclusions: This study summed up the broad information on occurrence of biologic-related hepatotoxicity in IBD patients in a clinical practice set-ting. When hepatotoxicity occurred, the treatment was withdrawn in 31% of patients, but an important percentage, 44%, were able to continue the full dose of thiopurine once the dose was temporarily adjusted. This group of patients had a dose-dependent hepatotoxicity rather than an immunologic hepatitis.
Driving Assistance System with Lane Change Detection

In this study, a simple technology for a self-driving system called “driver assistance system” is developed based on embedded image identification. The system consists of a camera, a Raspberry Pi board, and OpenCV. The camera is used to capture lane images, and the image noise is overcome through color space conversion, grayscale, Otsu thresholding, binarization, erosion, and dilation. Subsequently, two horizontal lines parallel to the X-axis with a fixed range and interval are used to detect left and right lane lines. The intersection points between the left and right lane lines and the two horizontal lines can be obtained, and can be used to calculate the slopes of the left and right lanes. Finally, the slope change of the left and right lanes and the offset of the lane intersection are determined to detect the deviation. When the angle of lanes changes drastically, the driver receives a deviation warning. The results of this study suggest that the proposed algorithm is 1.96 times faster than the conventional algorithm.
Entrepreneurial behaviour: The effects of the fear and anxiety of Covid-19 and business opportunity recognition

Objective: The major objectives of the article were to explore the effects of the fear and anxiety of Covid-19 and business opportunity recognition on start-up self-efficacy, entrepreneurial intention, and behaviour, as well as to test entrepreneurial intention-behaviour association. Research Design & Methods: The study was performed by means of an online survey questionnaire conducted on 405 students at a Vietnamese university. The survey questionnaire was developed based on prior research. Structural equation modelling (SEM) was utilised to test the research model and hypotheses. Findings: The results illustrated that the fear and anxiety of Covid-19 have a negative impact on start-up self-efficacy and entrepreneurial intention, while business opportunity recognition is strongly and positively correlated with entrepreneurial self-efficacy, entrepreneurial intention, and behaviour. In addition, entrepreneurial intention is found to be the most important antecedent to predict actual start-up behaviour whereas entrepreneurial intention significantly mediates the association between entrepreneurial self-efficacy and entrepreneurial behaviour. Implications & Recommendations: The study offers practical contributions for both universities and policymakers to foster youths' entrepreneurial activities and manage the negative outcome of Covid-19 on students' mental health. Contribution & Value Added: This research contributes to the entrepreneurship literature by addressing the notable gap when testing the linkages between entrepreneurial intention and behaviour. Furthermore, the finding confirms that the fear and anxiety of Covid-19 can decrease entrepreneurial self-efficacy, intention, and behaviour, while business opportunity recognition fosters entrepreneurial activities.
The motivational profile does matter: an exploratory survey on the influence of remote office work on physical behavior during the COVID19 lockdown

Background: Most office workers were forced to work remotely due to the COVID-19 global pandemic, possibly leading to a reconfiguration of settled patterns of physical behavior, often characterized by a sedentary lifestyle. This study aimed to investigate the motivational profile, facilitators, and barriers that might have influenced a change in physical activity while working remotely due to the COVID-19 lockdown.Methods: An online questionnaire was distributed in May-June 2020 including demographics, self-reported physical- and work behavior throughout the day before and during the lockdown, Sports Motivation Scale-II assessing motivation for being physically active, and rating on facilitators and barriers for engaging in physical activity during the lockdown. One-way ANOVA with Tukey post-hoc test was computed to investigate differences between those participants who become more-, less-, and equally active during the COVID-19 lockdown.Results: Ninety-nine people (Female=66) completed the questionnaire. Forty-four percent of the participants considered themselves less active than before the lockdown. Respondents reporting becoming more physically active (28%) were more intrinsically motivated than the remaining participants. The most important facilitators for physical activity were ‘good weather’, ‘no work-related travel’, and ‘flexible work schedules’. The most important barriers were ‘no active transportation’, ‘closed facilities’, and ‘work fatigue’. Conclusions: Strategies that adapt to the weather and fit the work schedule could facilitate physical activity among remote office workers. The results of this study will be used to design interventions to promote an active lifestyle among office workers, personalized to their motivation profile, needs, and preferences.
The development of electromobility in the aspect of the energy infrastructure condition assessment

Electric vehicles are considered emission-free. However, having high-emission and a high degree of electricity demand coverage infrastructure, these vehicles should be considered as internal combustion cars. The purpose of the analysis carried out in this study is to present the state of energy infrastructure in Poland, to determine losses related to energy transmission and greenhouse gas emissions to the atmosphere in relation to unit consumption. Analyzing the data obtained, the emission of the electric vehicle was compared to that of a vehicle powered by diesel oil and fuel with the addition of a biocomponent.
Boron-doped diamond as a new heating element for internal-resistive heated diamond-anvil cell

ABSTRACT We have developed an internal-resistive heated diamond-anvil cell (IHDAC) with a new resistance heater – boron-doped diamond (BDD) – along with an optimized design of the cell assembly, including a composite gasket. Our proposed technique is capable of heating a silicate/oxide material with (1) long-term stability (>1 h at 2500 K) and (2) uniform radial temperature distribution (±35 K at 2500 K across a 40-µm area), which are clear advantages over the conventional laser-heated and internal-heated DACs. In addition, the achieved temperature in this study was greater than 3500 K, which mostly covers the possible geotherm of the entire lower mantle. In situ X-ray diffraction (XRD) measurement and ex situ chemical analyses confirmed that weak XRD intensity from the BDD heater and chemical inertness (no boron diffusion into silicate samples). This newly developed IHDAC with a BDD heater can be used to determine the phase diagrams of mantle materials with high precision and be used in lower-mantle petrology.
Screening of gallate-based metal-organic frameworks for single-component CO2 and CH4 gas

Adsorption using porous adsorbents is widely applied in carbon dioxide (CO2) capture due to its potential energy saving with low operating cost. Metal-organic frameworks (MOFs) are preferable over conventional adsorbents as MOFs have tunable structure properties. Organic linkers from phytochemical-based give a new idea in forming MOFs. Gallic acid is classified under phytochemicals can act as an alternative organic linker in a new family of hybrid framework materials due to low cost, low toxicity, easy availability and naturally abundant. Due to unique property of MOFs that can be tailored, screening using systematic tool is very important. Molecular modeling is proven to play a crucial role in providing an estimation on adsorption capacity, selectivity and adsorbent selection. Grand Canonical Monte Carlo (GCMC) method via Sorption module in Material Studio was performed to compute loading curves of CO2 and methane (CH4) in MOFs. Based on the simulation results, it shows that gallate-based MOFs can be a new promising adsorbent in CO2 capture as the predicted CO2 loading is significantly higher than CH4. The highest predicted CO2 adsorption capacity is achieved by Mg-gallate and the lowest is by Ag-gallate with 7.79 mmol/g and 6.35 mmol/g respectively. The applicability of gallic acid to act as an alternative linker is relevant for practical applications.
Rhinolithiasis: A Case Report

Rhinolith is an uncommon nasal mass in children and adults. A case of a 40 yr old female having a 7 years history of right nasal obstruction and a foul smelling right nasal discharge, which was clinically and radiologically diagnosed to be rhinolith, is being reported here. Epistaxis and nasal obstruction are its most marked symptoms. The complete resolution of the symptoms is easily achieved by the surgical removal of the rhinolith. This case highlights the importance of examining the nasal cavities in any patient with unilateral nasal obstruction symptoms.
Br-Doped Bi2O2CO3 exposed (001) crystal facets with enhanced photocatalytic activity

A Br-Doped Bi2O2CO3 exposed (001) crystal facet was synthesized by a one-pot hydrothermal method. The results of the total densities of states of the valence band (VB) and UV-vis diffuse-reflectance spectrum (DRS) for the Br-doped Bi2O2CO3 exposed (001) crystal facet demonstrate that the doping of the Br anion can effectively narrow the band gap of Bi2O2CO3 by improving the valence band position. The photocatalytic performance is evaluated by degrading methyl orange (MO) and rhodamine B (RhB) dyes in an aqueous solution. In comparison with pure Bi2O2CO3, Br-doped Bi2O2CO3 exhibits drastically enhanced solar-light photoactivity, which is also superior to many other reported Bi2O2CO3-based photocatalysts. The highly enhanced photocatalytic performance is attributed to a combination of expanded photoresponse range caused by the doping of Br anions and effective separation of the photogenerated electron–hole pairs owing to the exposed active (001) crystal facet of Bi2O2CO3. The Br-doped Bi2O2CO3 exposed (001) crystal facet also shows photochemical stability, which is of special importance for its practical applications. This work demonstrates that doping enables band gap engineering and the design of high-performance photocatalysts.

A new compound of 1,3-bis(p-hydroxyphenyl) urea was designed and predicted to have fewer hepatotoxic side effects and as analgetic. Synthesis of 1,3-bis(p-hydroxyphenyl) urea could be carried out by reaction between p-aminophenol and urea. This study evaluated the mechanism of 1,3-bis(p-hydroxyphenyl) urea in inhibition of COX-1 and TNF-α with molecular docking. Docking was performed on the receptor file COX-1 (PDB ID: 1CQE) and TNF-α (PDB ID: 2AZ5) using AutoDock Vina PyRx 9.5 program and visualized by Ligplot 2.1 and PyMol 2.3. 1. Two and threedimension conformation models of compounds were generated by the MarvinSketch program. The docking score of ligand control, 1,3-bis(p-hydroxyphenyl) urea, diclofenac and dexamethasone towards 1CQE and 2AZ5 were -8.4; 10.6; -7.4 Kcal/mol and –9.2; -9.6; 7.1 Kcal/mol respectively. 1,3-bis(p-hydroxyphenyl) urea interacted with more amount of amino acid residues if compare with dexamethasone, diclofenac and ligand control.
Synthesis and Catalytic Activity of (3,4-Diphenylcyclopentadienone)Iron Tricarbonyl Compounds in Transfer Hydrogenations and Dehydrogenations

Four (3,4-diphenylcyclopentadienone)iron tricarbonyl compounds were synthesized, and their activities in transfer hydrogenations of carbonyl compounds and transfer dehydrogenations of alcohols were explored and compared to those of the well-established [2,5-(SiMe3)2-3,4-(CH2)4(η4-C4C═O)]Fe(CO)3 (3). A new compound, [2,5-bis(3,5-dimethylphenyl)-3,4-diphenylcyclopentadienone]iron tricarbonyl (7), was the most active catalyst in both transfer hydrogenations and dehydrogenations, and compound 3 was the least active catalyst in transfer hydrogenations. Evidence was found for product inhibition of both 3 and 7 in a transfer dehydrogenation reaction, with the activity of 3 being more heavily affected. A monomeric iron hydride derived from 7 was spectroscopically observed during a transfer hydrogenation, and no diiron bridging hydrides were found under reductive or oxidative conditions. Initial results in the transfer hydrogenation of N-benzylideneaniline showed that 3 was a significantly less active catalyst in .
Biochemical Effects of Vitamin A on Bladder Cancer

Among all urological cancers, Bladder Cancer (BC) is the tenth most common type of cancer worldwide, with approximately 549,000 new cases per year and 200,000 mortality. It is four times more common in males than females and is frequently seen in the sixth and seventh decades [1]. In addition to its negative effects on public health, BC is one of the cancer types with the highest cost of treatment due to its frequent recurrence [2]. For these reasons, the role of dietary factors, especially vitamins, in preventing BC has been studied frequently. In this mini review, we aimed to summarize that experimental and epidemiological studies investigating the relationship between vitamin A and BC.
The Influence of AC Driving Current on Magnetoimpedance in [Ni80Fe20/Cu]x/Cu/[Ni80Fe20/Cu]6-x Multilayers

The phenomenon of magnetoimpedance in the multilayer configuration of [Ni80Fe20/Cu]x/Cu/[Ni80Fe20/Cu]6-x with x = 1, 2, and 3 has been successfully investigated. The electrodeposition method used for the multilayer film preparation on the meander pattered of Cu PCB. The obtained multilayer samples were evaluated the MI effect at room temperature with a frequency of 100 kHz. Here, the MI effects were evaluated for a variation of the AC driving current i.e. IAC = 4 mA, 8 mA, 12 mA, 16 mA, and 20 mA. The MI measurement results show that the multilayer x = 3 has the largest MI ratio and the multilayer with x = 1 was the smallest one. It is indicated that interlayer coupling contributes to the MI effect. Whereas the skin depth also confirms to contribute the MI ratio that showed the MI ratio increase with the increase of the IAC.
Differentially Fed Dual-Mode Patch Antenna With Wideband Common-Mode Absorption and Its Array Application

A differentially fed dual-mode patch antenna is proposed with wideband common-mode (CM) absorption. The proposed antenna consists of a differential feeding network, common ground plane, and the radiation patch with stepped widths. The differential feeding network is formed by adding an absorptive stub at the symmetric plane of balanced microstrip structure to achieve wideband CM absorption. Besides, a T-shaped slot is etched on the ground plane to realize aperture coupling to excite the radiation under TM01 and TM11 modes. Subsequently, the differential parallel feeding technique is employed to design a $2 \times 4$ planar array with low cross polarization. As demonstration, the prototypes of the designed differential antenna and array are fabricated and measured. The measured results show that the proposed antenna element and array exhibit the broadened −10 dB impedance bandwidths covering the frequency range of 4.8–4.99 GHz, wide CM absorption band with about 70% fractional bandwidth, and low cross polarization below −20 dB. Furthermore, the measured peak realized gains of antenna and planar array are 7.5, and 16.6 dBi, respectively.
NEW COMMUNICATION TECHNOLOGIES AS A SOURCE OF WESTERN CULTURAL IMPERIALISM IN NIGERIA: A STUDY OF AWKA METROPOLIS IN ANAMBRA STATE

This study aimed at investigating new communication technologies as a source of western cultural imperialism in Nigeria; a study of Awka metropolis in Anambra State. Anchored on the framework of the Social Learning Theory, it delved into investigating the nature and the extent of domination using a survey of 100 respondents from Awka metropolis in Awka South local government area of Anambra State. The study adopted Survey method as the research design . A sample of 100 respondents were selected via the multi-stage approach. Data analysis was quantitative using simple percentages and Pearson’s Chi square test. Findings indicate that residents of Awka metropolis are adequately exposed to these new electronic communication technologies and that these technologies are potential channels for foisting western (and in particular American) culture on the people while possibly eroding the indigenous culture. For this reason, it is recommended among others that Nigeria should adopt protectionism (a system of using legal mechanisms to regulate media content so as to guard against domination) as a means of controlling western cultural imperialism.
Highly efficient MOF-based self-propelled micromotors for water purification

Self-propelled metal–organic framework (MOF)-based Janus micromotors that propel autonomously in hydrogen peroxide and display effective remediation of contaminated water is presented in this work. The novel Janus micromotors rely on the asymmetric deposition of a catalytically active Ag patch on the surface of MOF composite microspheres. The active Ag sites are used for the splitting of H2O2 to form oxygen bubbles. As a result, these Janus micromotors can reach a high speed of over 310 μm s−1 due to effective bubble propulsion, which is comparable to common Pt-based micromotors. By coupling the high catalytic capacity of MOFs with their autonomous propulsion, the MOF-based micromotors are shown to play a dominant role in the effective removal of organic pollutants. In addition, scanning electronic microscopy, Fourier-transform infrared spectroscopy and energy dispersive X-ray spectroscopy are performed to verify their morphology and composition. Based on the obtained results, a potential mechanism of the motion and the high catalytic activity is also proposed. It is expected that these energy saving micromotors with catalytic activity should be unprecedentedly spread in real applications.
Data Management Platforms: An Empirical Taxonomy

Data management platforms (DMPs) are a widely used means of placing targeted advertising, for example, commercial or political advertisements. However, only a few academic papers shed light on the platforms’ mechanisms. These mechanisms’ opacity makes it hard for consumers to understand what happens with their data, and regulators struggle to implement effective regulations. Hence, we develop a taxonomy to understand and compare different characteristics of DMPs. Following Nickerson’s (2013) method and combining an inductive and deductive approach, eight dimensions emerge that differentiate DMPs. We evaluate the taxonomy’s applicability and test it with a set of nine DMPs, which we select by feasibility, relevance, and popularity. The application shows that the eight dimensions cover the significant features that explain most of the variance in characteristics between DMPs. The evaluation revealed opportunities for further development of the taxonomy

Investigation of compact dual port octagonal MIMO antenna with triple band rejection capabilities with good isolation

This papers focuses to investigate a 35mm*60mm*1.6mm novel dual port MIMO antenna with triple notch rejection capabilities that exhibits good isolation performances. An Octagonal radiating patch is incorporated with defected ground structure and relevant slots in the radiator. Two slots and DGS contribute for the rejection capabilities of potential interference bands like WIMAX,WILAN, and X band in the ultra-wide band region of the designed antenna. Further to improve its performance, the antenna is modified as dual port MIMO which experiences mutual coupling. A strip line is introduced above the radiating patches in the substrate to obstruct the surface waves and to reduce the mutual coupling between the radiating elements. Crucial parameters like mutual coupling and the diversity gain are analyzed and are found to be promising. The proposed variant’s impedance bandwidth spans from 1.5 GHz to 9.05 GHz.
