Should we or should we not? Examining travelers' perceived privacy, perceived security and actual behavior in online travel purchases

The purpose of this study is to examine travelers’ actual behavior with regard to an online travel purchase by extending the Unified Theory of Acceptance and Use of Technology (UTAUT2) with two new variables, i.e. perceived privacy and perceived security. The study implements a quantitative research design and developed an e-questionnaire. Data was collected from 485 travelers via online platform (Amazon M-Turk). To empirically validate the proposed model and test the inter-relationships between the variables, we performed the SEM analysis on the data. The study findings reveal that facilitating conditions, habit and purchase intention act as significant predictors of travelers’ actual behavior toward online travel purchase. The result also shows that perceived privacy does not impact travelers’ purchase intention while, experience positively moderates the relationship between purchase intention and actual purchase. This study chooses an under explored area and examines the influence of perceived security and perceived privacy in the context of online travel purchase. Further, this study is the leading scholarly work which examines the moderating role of experience between travelers’ purchase intention and actual purchase in tourism context.
Occurrence of Macro- and Micro-Plastics on Pasir Pandak Beach, Sarawak, Malaysia

Highlight Research The present of microplastics is more than macroplastics on the Pasir Pandak Beach The existence of huge amount of smaller microplastics (<0.50 mm) were observed on this beach sediment Types of macroplastics found are fragment, foam, and fiber; while microplastics are fiber, filament, fragment, and foam The main polymers found are HDPE, PES, PP, and PS Clean Coast Index indicated Pasir Pandak Beach as an extremely dirty beach Abstract Pasir Pandak Beach is close to human settlements, resorts, and food stalls. It becomes a place for gathering of beachgoers especially during weekend. As a result, the beach became polluted with rubbish, particularly plastics (e.g., macro- and micro-plastics). Hence, this study was done to determine the occurrence of macro- and micro-plastics on the Pasir Pandak Beach, Kuching, Sarawak, Malaysia. Transect quadrat was used during the samples collection on the beach. The samples were then undergone the wet peroxide oxidation, filtering and classifying under dissecting microscope. Macroplastics were isolated for ATR-FTIR and SEM analyses, while microplastics were separated according to their sizes, colors, and types. Approximately 101.70 items/m2 of macro-plastics and 1084 items/m2 of micro-plastics were found in this study. Clean Coast Index (CCI) was also estimated and the calculated CCI value obtained was >20, which indicated as extremely dirty beach. Fragments of carpet/canvas/mat and hardware crate/item were the most abundance macroplastics found, followed by plastic ropes/fishing lines and bottle caps. HDPE, PES, PP, and PS were the main identified polymers. Fibers, filaments, fragments, and foams were identified for micro- and macro-plastics. Microplastics with smaller sizes of 0.25-0.50 mm were available abundantly and they comprise 63.47 % of the total microplastics found. Clear/white, black, and blue were the main colors for microplastics. SEM images presented that those adhering particles, grooves, pits, fractures, and flakes were the common patterns of degradation. No relationship was apparent between macro- and micro-plastics at each station. The abundance of macro- and micro-plastics showed that they were mainly controlled by the land-based input. As Pasir Pandak beach is busy with local communities and beachgoers, the presence of macro- and micro-plastics on the beach posing a severe threat for marine environment, thus further studies on the behavior of this emerging pollutant from beach to the seas are necessary.
A Statistical Description of Pressure and Velocity Fields at the Trailing Edges of a Flat Strut

Abstract : An experimental determination has been made of the turbulent field quantities which exist at trailing edges. The investigation was carried out on a rigid strut with parallel sides and circular leading edge; the strut was not yawed to the flow. Discussions cover broad cases of (1) trailing edges that produce periodic wakes, and (2) trailing edges that produce random wake structures. In each case, the time-averaged, boundary-layer characteristics; streamwise turbulence intensities; and fluctuating surface pressures have been spatially mapped in the region of each edge. Correspondence between surface pressures and turbulent fields in both the immediate vicinity and the far wake of each edge were determined by correlation analyses. Results show a mechanism of pressure production which is common to both random and periodic pressures. They also indicate that the mechanism differs from that which produces attached boundary-layer--wall-pressure fluctuations.
Benchmark values for monoenergetic neutron transport in one-dimensional cylindrical geometry with linearly anisotropic scattering

The integral transform method (IT /SUB N/ ) has been extended to the treatment of one-dimensional homogeneous media with linearly anisotropic scattering. A previously obtained formula linking the isotropic and the anisotropic one-dimensional kernels allows for calculation of the anisotropic matrix elements in the form of linear combinations of a few isotropic matrix elements. In practice, to solve the anisotropic problem of order N one needs only to calculate the isotropic collision matrix of order (N + 2) in plane and spherical geometries and of order (N + 1) in cylindrical geometry. The method is applied to the calculation of critical parameters for bare cylinders. Highly accurate values, to be used as benchmarks, are obtained and illustrate the precision and fast convergence rate of the method.

It gives a brief overview of the present and methods recommended for EV charging.
Numerical Analysis of High Speed Flow Applications using Various Flux Schemes

Numerical analysis using computational fluid dynamics is an affordable and effective method with increasing relevance every day in research and engineering problems. Choosing an appropriate convective discretization scheme is paramount importance for obtaining more accurate solutions using CFD methods. The present study compares two commonly used numerical convective schemes, the upwind scheme of Advection Upstream Splitting Method (AUSM) and the central schemes of Kurganov-Noelle-Petrova and Kurganov-Tadmor scheme (K-T) have been made to find the better central scheme. These two schemes are validated with inviscid 1D and 2D problems such as Sod’s shock tube, forward facing step in a Mach 3 tunnel, 15 Degree ramp in a Mach 2 supersonic tunnel, the Mach-reflection problem and scramjet engine operating under high Mach number. The AUSM and K-T schemes are robust enough to capture all the features of compressible flows. Comparison of results obtained by these 2 schemes is presented using density contours and surface property changes. It has been observed that both the schemes are robust enough to capture the flow features of the problems and that they have better accuracy for different conditions. HIGHLIGHTS This paper focuses on two convective flux discretization techniques i.e. the upwind scheme of AUSM and the central schemes of K-T and KNP Inviscid simulations for various problems in the supersonic as well as hypersonic regime were used in Sod’s 1-Dimensional Shock Tube, flow over forward facing step in supersonic wind tunnel and Mach 5 flow thorough scramjet engine The AUSM and K-T schemes are robust enough to capture all the features of compressible flows. It has been observed that both the schemes are robust enough to capture the flow features of the problems and that they have better accuracy for different conditions GRAPHICAL ABSTRACT
The Use of Biocompatible Membranes in Oral Surgery: The Past, Present & Future Directions. A Narrative Review

The use of biocompatible membranes in periodontal and oral surgery is an important part of regeneration. Over the years, several different membranes have been developed, ranging from non-resorbable membranes that have to be removed in a separate procedure, to collagen membranes that completely resorb on their own, thus avoiding the need for a second surgery. Autogenous membranes are becoming increasingly popular in more recent years. These membranes can be used with a great variety of techniques in the four main hard tissue regenerative procedures: guided tissue regeneration, alveolar ridge preservation, guided bone regeneration and sinus floor augmentation. A review of the literature was conducted in order to identify the most commonly used membranes in clinical practice, as well as the most promising ones for regeneration procedures in the future. The information provided in this review may serve as a guide to clinicians, in order to select the most applicable membrane for the clinical case treated as the correct choice of materials may be critical in the procedure’s success.
Boundedness in a two-dimensional chemotaxis-haptotaxis system

This work studies the chemotaxis-haptotaxis system $$\left\{ \begin{array}{ll} u_t= \Delta u - \chi \nabla \cdot (u\nabla v) - \xi \nabla \cdot (u\nabla w) + \mu u(1-u-w), &\qquad x\in \Omega, \, t>0, \\[1mm] v_t=\Delta v-v+u, &\qquad x\in \Omega, \, t>0, \\[1mm] w_t=-vw, &\qquad x\in \Omega, \, t>0, \end{array} \right. $$ in a bounded smooth domain $\Omega\subset\mathbb{R}^2$ with zero-flux boundary conditions, where the parameters $\chi, \xi$ and $\mu$ are assumed to be positive. It is shown that under appropriate regularity assumption on the initial data $(u_0, v_0, w_0)$, the corresponding initial-boundary problem possesses a unique classical solution which is global in time and bounded. In addition to coupled estimate techniques, a novel ingredient in the proof is to establish a one-sided pointwise estimate, which connects $\Delta w$ to $v$ and thereby enables us to derive useful energy-type inequalities that bypass $w$. However, we note that the approach developed in this paper seems to be confined to the two-dimensional setting.
Finite factorization domains

An integral domain R is a (cid:12)nite factorization domain if each nonzero element of R has only (cid:12)nitely many divisors, up to associates. We show that a Noetherian domain R is an FFD , for each overring R 0 of R that is a (cid:12)nitely generated R -module, U ( R 0 ) =U ( R ) is (cid:12)nite. For R local this is also equivalent to each R= [ R : R 0 ] being (cid:12)nite. We show that a one-dimensional local domain ( R; M ) is an FFD , either R=M is (cid:12)nite or R is a DVR.
Characterization of Selective and Potent JAK1 Inhibitors Intended for the Inhaled Treatment of Asthma

Purpose Janus kinase 1 (JAK1) is implicated in multiple inflammatory pathways that are critical for the pathogenesis of asthma, including the interleukin (IL)-4, IL-5, IL-13, and thymic stromal lymphopoietin cytokine signaling pathways, which have previously been targeted to treat allergic asthma. Here, we describe the development of AZD0449 and AZD4604, two novel and highly selective JAK1 inhibitors with promising properties for inhalation. Methods The effects of AZD0449 and AZD4604 in JAK1 signaling pathways were assessed by measuring phosphorylation of signal transducer and activator of transcription (STAT) proteins and chemokine release using immunoassays of whole blood from healthy human volunteers and rats. Pharmacokinetic studies performed on rats evaluated AZD0449 at a lung deposited dose of 52 μg/kg and AZD4604 at 30 µg/kg. The efficacy of AZD0449 and AZD4604 was assessed by evaluating lung inflammation (cell count and cytokine levels) and the late asthmatic response (average enhanced pause [Penh]). Results Both compounds inhibited JAK1-dependent cytokine signaling pathways in a dose-dependent manner in human and rat leukocytes. After intratracheal administration in rats, both compounds exhibited low systemic exposures and medium-to-long terminal lung half-lives (AZD0449, 34 hours; AZD4604, 5 hours). Both compounds inhibited STAT3 and STAT5 phosphorylation in lung tissue from ovalbumin (OVA)-challenged rats. AZD0449 and AZD4604 also inhibited eosinophilia in the lung and reduced the late asthmatic response, measured as Penh in the OVA rat model. Conclusion AZD0449 and AZD4604 show potential as inhibitors of signaling pathways involved in asthmatic immune responses, with target engagement demonstrated locally in the lung. These findings support the clinical development of AZD0449 and AZD4604 for the treatment of patients with asthma.
A Retrospective Study on Clinical Assessment of Cognitive Impairment in a Swedish Cohort: Is There Inequality Between Natives and Foreign-Born?

Background: People with a migration background are underrepresented in dementia research and disfavored in assessment and treatment, and many foreign-born individuals with dementia remain undiagnosed. Objective: The aim of this study was to examine whether there is inequality in the clinical assessment of dementia between native and foreign-born individuals in Sweden. Methods: Information was gathered retrospectively from a cohort of 91 native and 36 foreign-born patients attending four memory clinics in Skåne, Sweden. Data included information on cognitive test results, cerebrospinal fluid biomarkers, scores at structural imaging scales of global cortical atrophy (GCA), medial temporal lobe atrophy (MTA) and the Fazekas scale, laboratory measures of thyroid-stimulating hormone, calcium, albumin, homocysteine, hemoglobin, cobalamin (vitamin B12), and folate (vitamin B9), contact with health care, and treatment. Results: Foreign-born patients had lower educational level and scored lower on Mini-Mental State Examination and Clock Drawing Test (p < 0.001–0.011). Relatives initiated contact with health care to a higher extent in the foreign-born group (p = 0.031). Foreign-born patients had less white matter lesions (p = 0.018). Additionally, Alzheimer’s disease (AD) biomarkers were significantly less used in foreign-born patients to support an AD diagnosis (p = 0.001). No significant differences were found for scores on GCA and MTA, laboratory measures, or initiated treatment. Conclusion: Although native and foreign-born patients were predominantly homogenous regarding examined variables, differences in the diagnostic process and underlying biological correlates of dementia exist and need to be further investigated in a larger sample.
The I-Band Tully-Fisher Relation for Sc Galaxies: Optical Imaging Data

Properties derived from the analysis of photometric I-band imaging observations are presented for 1727 inclined spiral galaxies, mostly of types Sbc and Sc. The reduction, parameter extraction, and error estimation procedures are discussed in detail. The asymptotic behavior of the magnitude curve of growth and the radial variation in ellipticity and position angle are used in combination with the linearity of the surface brightness falloff to fit the disk portion of the profile. Total I-band magnitudes are calculated by extrapolating the detected surface brightness profile to a radius of eight disk scale lengths. Errors in the magnitudes, typically ∼0.04 mag, are dominated by uncertainties in the sky subtraction and disk-fitting procedures. Comparison is made with the similar imaging database of Mathewson, Ford, & Buchhorn, both as presented originally by those authors and after reanalyzing their digital reduction files using identical disk-fitting procedures. Direct comparison is made of profile details for 292 galaxies observed in common. Although some differences occur, good agreement is found, proving that the two data sets can be used in combination with only minor accommodation of those differences. The compilation of optical properties presented here is optimized for use in applications of the Tully-Fisher relation as a secondary distance indicator in studies of the local peculiar velocity field.
Heat shock protein and antioxidant enzyme gene expression and fold changes in bone marrow samples from healthy rats

The hematopoiesis in the bone marrow in the early stages of life is very complex and involves many cellular factors under very strict micro-environments. The two important cellular factors are heat shock proteins and antioxidant enzymes. The aim of the study was to study the gene expression profile of healthy rats’ bone marrow cells and niches particularly heat shock proteins and antioxidant genes. A total of thirty healthy Wister Albino rats at one, two, and three months old were involved throughout the study. Bone marrow samples were collected at a specified date according to the study design and utilized for qPCR test for expression of Hsps27, 90α, 90β, and antioxidant enzymes glutathione peroxidase1 (GPX1), catalase CAT and superoxide dismutase (SOD3) genes. The results revealed that there was a clear expression of both Hsps90α andβ in bone marrow cells throughout the study as well as the GPX1 gene. Furthermore, there was an increase in fold change of Hsps90α and β as well as GPX1, CAT, and SOD3 proteins as age progressed. In conclusion, hematopoietic cell differentiation and proliferation are regulated by bone marrow microenvironment stress conditions and by the expression of different Hsps and antioxidant genes. The protein folding process is a defense mechanism to protect the HSCs, and progenitors from un/misfolded proteins and to keep proteostasis.
Infrared polarimetry and integral field spectroscopy of post-asymptotic giant branch stars

Krispian Tom Edward Lowe infrared Polarimetry and Integral Field Spectroscopy of Post-Asymptotic Giant Branch Stars University of Hertfordshire, 2008 In this thesis, I present the properties of IRAS 19306+1407 central source and its surrounding circumstellar envelope (CSE), from the analysis of near-infrared (near-IR) polarimetry and integral field spectroscopy (IFS), with supporting archived HST images and sub-millimetre (sub-mm) photometry. This is supported by axi-symmetric light scattering (ALS), axi-symmetric radiative transfer (DART) and molecular hydrogen (H2) shock models. The polarimetric images show that IRAS 19306+1407 has a dusty torus, which deviates from axisymmetry and exhibits a ‘twist’ feature. The DART and ALS modelling shows that the CSE consists of Oxygen-rich sub-micrometre dust grains, with a range in temperature from 130±30 to 40±20 K at the inner and outer radius, respectively, with inner and outer radii of 1.9±0.1×10 and 2.7±0.1×10 m. The CSE detached 400±10 years ago and the mass loss lasted 5700±160 years, assuming a constant asymptotic giant branch (AGB) outflow speed of 15 km s. The dust mass and total mass of the CSE is 8.9±5×10 and 1.8±1.0×10 −1 M⊙, assuming a gas-to-dust ratio of 200. The mass loss rate was 3.4± 2.1× 10 M⊙ year . The central source is consistent with a B1I-type star with a radius of 3.8 ± 0.6 R⊙, luminosity of 4500 ± 340 L⊙ at a distance of 2.7 ± 0.1 kpc. A purpose built idl package (fus) was developed and used in the SINFONI IFS data critical final reduction steps. It also produced emission line, kinematic and line
Chemical and Genetic Variability of Istrian Foeniculum vulgare Wild Populations

Wild Foeniculum vulgare populations from the region of Istria have been subjected to a genetic and chemical study. Headspace-gas chromatography analysis of volatile secondary metabolites and PCR-RFLP analysis of the ribosomal DNA internal transcribed spacer region has been chosen to analyze the chemical and genetic traits of single plants, respectively. Large intrapopulation and interpopulation differences have been observed in both chemical profiles and restriction patterns of PCR products. The data from chemical and genetic analyses were pooled and used to assess allele frequencies of three putative genetic loci on individual populations. The pooled allele frequencies were used to determine interpopulation distances for phenogram reconstruction. The combined use of chemical and genetic datasets for genetic variation analysis proved to be a more comprehensive approach for such a study, compared to the use of single datasets, even using such relatively simple analytical tools.
Globularia alypum Extracts Attenuate Hyperglycemia and Protect against Various Organ Toxicities in Alloxan-Induced Experimental Diabetic Rats

In this study, we attempted for the first time to determine the phytochemical compositions and biopharmaceutical properties of Globularia alypum methanol extract (GAME) and Globularia alypum water extract (GAWE). High-performance liquid chromatography with diode array detection (HPLC-DAD) analysis was performed to establish the chemical profile of the investigated extracts. Chemical composition analysis was taken in the presence of various bioactive compounds such as quercetin 7-O-glucoside and apigenin 7-O-glucoside in GAME. In GAWE, various abundant compounds were found in the extract such as quercetin 7-O-glucoside, apigenin, quercetin, apigenin 7-O-glucoside, and cinnamic acid. This study showed that the administration of GAWE and GAME to type 1 diabetic rats decreased fasting blood glucose, protected pancreas β-cells from death and injury, increased liver glycogen rate, and ameliorated oral glucose tolerance test. Moreover, GA reduced weight loss, and diabetes decreased basic physical activity. In addition, the administration of GA extracts in diabetic rats protected from diabetes-induced liver, kidney, testes, heart, and bone toxicities. Conclusion. GAWE has possible value for antidiabetic oral medication.
Structures affinées et pseudo-métriques invariantes à gauche sur des groupes de Lie

Le but de ce travail est double. D'une part etudier les groupes de lie affine (i. E. Munis d'une structure affine invariante a gauche) dont la structure affine est liee a une pseudo-metrique invariante a gauche. Nous prouvons en particulier les resultats suivants: la structure affine d'un groupe de lie pseudo-riemannien plat est geodesiquement complete si et seulement si le groupe est unimodulaire. La variete cotangente d'un groupe de lie connexe et simplement connexe est munie d'une structure de groupe de lie pseudo-riemannien plat. D'autre part, introduire une technique dite de double extension, inspiree de celle de medina-revoy, capable de decrire les algebres de lie de certains groupes de lie affines a pseudo-metrique invariante a gauche hessienne. C'est ainsi que nous caracterisons les algebres de lie. Des groupes de lie nilpotents lorentziens plats des groupes de lie pseudo-riemanniens plats ou la connexion de levi-civita est bi-invariante des groupes de lie a structure affine et a pseudo-metrique localement hessienne bi-invariantes des groupes de lie symplectiques a pseudo-metrique bi-invariante
