Purpose

To investigate a set of risk factors on the outcome of Ponseti treated idiopathic clubfeet (ICF).

Methods

This study was approved by the institutional review board. A retrospective analysis of prospectively gathered data over a 20-year period, at a single dedicated clubfoot clinic. Records of 333 consecutive infants with 500 ICF were analyzed. Initial Pirani score, number of casts, need for tenotomy, foot abduction brace compliance and functional score had been documented. The need for surgery after initial correction was the outcome measure. All children were followed by the same team throughout the study period. Descriptive statistics, chi-squared and multivariate analysis were performed.

Results

In total, 82 children (24%) with 119 feet (23.8%) were operated on, with 95.1% of feet being operated up to the age of nine years. There was a significant correlation between the Pirani score at presentation and the number of surgical procedures (chi-squared = 79.32; p < 0.001). Achilles tenotomy was done in 94.8% of patients. Pirani score of > 4.5 before casting was strongly associated with increased surgical risk (odds ratio = 1.95). When six to eight cast changes were needed, surgical prospect was 2.9 more, increasing to 11.9 when nine or more casts were needed.

Conclusion

Foot severity and number of cast changes were the strongest predictors for future surgery. Estimation of the risk of deformity recurrence after initial correction may help in tailoring a cost-effective personal treatment and follow-up protocol. Personalized focused protocol will help patients and caregivers and will reduce expenses.

Outcome after Two Sequential Revision Hip Arthroplasties for CoC Bearing Fracture with 10 Years Follow-up: A Case Report
Authors: Topolovec Matevž , Milošev Ingrid , Cör Andrej
Published: October 2021

Introduction: Revisions due to the fracture of ceramic-on-ceramic (CoC) bearing are rare, however when they occur, they represent a major challenge to an orthopedic surgeon for ensuring safe and long-term survival of the replaced bearing.
Case Report: We present a case of fractured ceramic liner of total hip prosthesis that underwent revision to a metal-on-polyethylene (MoP) bearing couple, with consequent huge periprosthetic metallosis. Shortly after, the second revision operation followed using the third bearing couple of ceramic-on-polyethylene (CoP). At 10 years follow-up after the operation due to ceramic fracture, the patient is now pain free with full range of motion of the revised hip.
Conclusion: Establishment of diagnostic routes and recommended protocols for CoC bearing fracture would allow easier recognition of potential fracture and diminish its consequences for the patients.

Published: October 2021

Introduction: Simultaneous fractures in the neck of femur on the one side and contralateral intertrochanteric fracture of the femur with only trivial injury are among rarest injuries. Fracture neck of femur or intertrochanteric fracture either isolated or in combination such as simultaneous bilateral fracture neck of femur and simultaneous bilateral intertrochanteric fractures are relatively commonly reported in literature. Herein, we report a very rare case of a young female with chronic kidney disease who presented with simultaneous fractures neck of femur on the one side and contralateral intertrochanteric fracture of femur after a fall from standing height.
Case Report: A 41-year-old female with chronic kidney disease from the past 5 years presented to us with severe pain at both hip and inability to stand after a fall from standing height. Clinical examination and investigations were done. She suffered fracture neck of femur on the right side and intertrochanteric fracture femur on the left side. Single stage fixation of both these fractures by two different methods was done successfully after optimization of her medical condition with multidisciplinary approach. She was advised weight bearing according to fixation method used and progress of fracture union. She regained her preoperative walking status gradually in 6 months.
Conclusion: Simultaneous fractures in the neck of femur on the one side and intertrochanteric fracture of the femur on the other side are very rare presentation and can happen in patients with primary or secondary bone disease. Multidisciplinary team effort is needed for overall effective management and prompt surgical treatment can help achieve favorable outcome.

Salter-Harris I Injury of the Proximal Tibial Physis with Vascular Compromise: A Case Report and Review of Literature
Authors: Yadav Rajeev , Kasotya Devender , Goel Akash , Bhatia Nishant , Yadav Vedpal
Published: October 2021

Introduction: Physeal injuries of proximal tibia are uncommon and constitute only 1% of all physeal injuries. Major vessel injuries are also rare in children and occur in 0.6% trauma cases, out of which, injuries of popliteal artery comprise only 5%. The combination of these is an extremely rare injury pattern but is potentially limb threatening. Most of the cases of physeal injuries of proximal tibia along with popliteal artery compromise, reported in the literature include Salter Harris (SH) type II, III, and IV patterns (type II being most common) with pure type I being extremely rare.
Case Report: We describe a rare posteriorly displaced pure SH I injury of proximal tibial physis with compromised vascularity of the limb. Immediate closed reduction and stabilization with Kirschner wires (K-wires) restored the vascularity of the limb and the patient went on to have a good functional recovery at the last follow-up of 1 year.
Conclusion: Vascular injuries occurring in SH 1 proximal tibial physeal fractures are often overlooked or missed due to the relatively benign appearance of slip with no sharp fragments to injure major vessels. Close monitoring of neurovascular status and a low threshold for fixation, for example, with K-wires, are important to prevent limb threatening ischemia in these relatively simple appearing injuries.

Published: October 2021

Introduction: Ochronotic arthropathy in patients with alkaptonuria is a rare hereditary disorder. The altered metabolism causes the homogentesic acid derivatives to deposit in various connective tissues causing characteristic pigmentation. Due to the close clinical resemblance to that of a degenerative disorder, diagnosis of ochronotic arthropathy usually occurs intraoperatively. We report arthroscopic findings of a 50-year-old female with ochronotic arthropathy.
Case Report: A 50-year-old woman came with complaints of pain and swelling in the left knee. Clinical examination and MRI findings were correlated to reveal a tear of lateral meniscus. On arthroscopic examination, the blackish pigmentation of the meniscus and the articular cartilage led to the diagnosis of ochronotic arthropathy.
Conclusion: Arthroscopy plays an important role in diagnosis and treatment of patients with ochronotic arthropathy. The characteristic arthroscopic finding may aid diagnosis even in patients who do not have other systemic manifestations. Timely arthroscopic intervention can help delay the disease progression.

Published: October 2021

BACKGROUND New therapeutic options are often explored in in vivo studies using animals like rats. Since rats are small, it is difficult to examine them in a computed tomography (CT) scan. This study aimed to introduce a multi-hole spherical model CT scan method as a new, fast, economical, and reliable method to characterize large quantities of rat bones at once in estimating the timing of osteoporosis in ovariectomized white rats.

METHODS 50 female white rats (12 weeks old) were treated as the control group, and 40 rats of the same age were ovariectomized to establish the osteoporosis model. Sham rats were sacrificed at 13, 15, 17, 19, and 21 weeks old, while the ovariectomized rats were sacrificed at 15, 17, 19, and 21 weeks old. Afterward, tibia bones were removed, placed in the multi-hole spherical model, and characterized using a CT scan. Their characteristics were compared using a scanning electron microscope (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD).

RESULTS The Hounsfield unit scores resulted from the multi-hole spherical model CT scan method of tibia bones of rats were consistent with the percentage of the osteocyte cavities, canalicular diameters, and crystal size. The multi-hole spherical model CT scan method could produce 50 times more data than the SEM, TEM, or XRD.

CONCLUSIONS Multi-hole spherical model CT scan was considered good and reliable in assessing bone quality parameters in rat samples simultaneously.
From being ‘at risk’ to being ‘a risk’: journeys into parenthood among young women experiencing adversity
Authors: Blaxland Megan , Skattebol Jennifer , Hamilton Myra , van Toorn Georgia , Thomson Catherine , valentine kylie
Published: October 2021

When young women who have grown up in contact with child protection become mothers, they shift from being regarded as a child ‘at risk’ by the child protection system, to posing ‘a risk’ to their baby. In contrast to their peers, young care leavers transition to adulthood with very few resources and little support; they typically continue to experience the economic and related adversities of their childhoods. This article draws on biographical narrative interviews with young Australian mothers to understand how they navigate child protection as new mothers. We argue that, while inequalities endure, new understandings of the system can be acquired and dispositions can adapt to function more effectively in the field of child protection. We draw on Bourdieu’s notions of capital, habitus and field to analyse young mothers' adaptations, with additional insights from Hester’s analogy of separate planets to explore their experiences of the field of child protection.
Method for tilt correction of calibration lines in high-resolution
spectra
Authors: Das Tanya , Banyal Ravinder K.
Published: October 2021

Technological advancement has led to improvement in the design capabilities of astronomical spectrographs, allowing for high-precision spectroscopy, thereby expanding the realms of observational astronomy. High-resolution spectrographs use echelle gratings that operate in higher orders, giving more detailed spectra. Often, curvature and tilted lines are observed in the spectra, arising due to the design trade-offs of the respective spectrographs. Removal of these artifacts can help avoid wrong flux calculation and line centroid position misinterpretation, which can aid in a better prediction of the wavelength calibration model. In this paper we present a postprocessing technique that we developed to correct the observed curvature and tilt in the spectra. We have demonstrated the correction technique on Fabry–Perot and Th-Ar calibration spectra obtained from a Hanle echelle spectrograph, a Magellan Inamori Kyocera Echelle spectrometer, and a X-Shooter spectrograph.
Plasmonic octamer objects: reversal of near-field optical binding force without the aid of backgrounds

Published: October 2021

In recent years, the near-field optical binding force has gained a lot of interest in the field of optical manipulation. The reversal of the near-field binding force, a new, to the best of our knowledge, kind of optical manipulation, has so far been investigated mostly between dimers and in a very few cases among tetramers by utilizing the help of suitable substrates or backgrounds. Until now, no known way to control the near-field optical binding force among octamer configurations has been found, to our knowledge. In this paper, we propose a plasmonic (silver) octamer configuration where we demonstrate the control and reversal (attraction and repulsion) of the near-field optical binding force of octamers by illuminating the system with a TM polarized Bessel beam. The control of the binding force and its reversal is explained based on the polarization and gradient forces created by the Bessel beam. As the aid of a background or substrate is not required, our proposed simplified approach has the potential to open up novel ways of manipulating multiple particles. Our investigation also implicitly suggests that for future research on controlling the reversal of the near-field optical binding force of multiple particles, Bessel beams can be the appropriate choice instead of plane waves.
Remote angular velocity measurement by the cascaded rotational Doppler effect
Authors: Guo Zhenyu , Meng Jinglin , An Min , Cheng Pengxiang , Jia Junliang , Chang Zehong , Wang Xiaoli , Zhang Pei
Published: October 2021

The rotational Doppler effect has attracted extensive attention, caused by the angular momentum and energy exchange between rotating objects and waves. However, most previous works used a simple rotation frame, which made use of only a single-round angular momentum and energy exchange. We propose and demonstrate a frame containing a spiral phase plate cascaded with rotating targets to make an amplification of the traditional Doppler shift, and reduce the diffusion of orbital angular momentum modes by half, which means the distance of practical application is doubled theoretically. To this end, an experiment is carried out to verify the frame. It shows a more practical, convenient, and non-destructive method to measure the rotational speed of a remote target.

Fourier transform infrared (FTIR) spectra of aqueous mixtures of urea and dimethylurea solutions were recorded in the 1250–2500 nm wavelength range in thin-layer quartz cuvettes at room temperature. The spectra reveal suitable detection wavelengths, i.e., 1450, 1933, 2200, and 2270 nm, for which both the absorption coefficient and its variation with the species concentration are large enough to achieve satisfactory detection sensitivity and selectivity. For validation measurements, samples were prepared in thin-layer quartz transmission cells with known path lengths and mixture compositions in the range 100–1000 µm and 0–40 wt.%, respectively. Film thickness and mass fractions of both species were determined from measured absorbance ratios in the determined characteristic wavelength bands.
Strong interaction between two photons and a plasmon of a complementary metamaterial in a terahertz dual cavity
Authors: Meng Fanqi , Thomson Mark D. , Klug Bernhard , Roskos Hartmut G.
Published: October 2021

Guided by Babinet’s principle, we explore strong coupling between the effective magnetic dipole moments of complementary split-slotring metamaterials and the magnetic field of a cavity radiation mode. The strong coupling is demonstrated by a pronounced Rabi splitting of the cavity polariton resonances, corresponding to the ultrastrong coupling regime, with the metamaterial placed at a magnetic-field anti-node of the bare cavity radiation mode, where the corresponding electric field vanishes and no strong interaction was previously observed with a metamaterial consisting of electric dipole resonators. Moreover, exploiting the complementary bandpass/bandstop characteristics of the split-slotring resonators, we realize a dual cavity, coupled via the intermediate metamaterial, and observe strong interaction among two photons and the plasmon in the cavity. When the dual cavity is degenerate, the three-particle interaction collapses to an effective two-particle interaction, where the generalized Rabi splitting is increased by a factor of

compared to the single-cavity case involving only one photon and one plasmon. The experimental results are supported both by classical electromagnetic simulations and coupled-oscillator models adopted from cavity quantum electrodynamics.
Inverse design of the MMI power splitter by asynchronous double deep Q-learning
Authors: Xu Xiaopeng , Li Yu , Huang Weiping
Published: October 2021

The asynchronous double deep Q-learning (A-DDQN) method is proposed to
design the multi-mode interference (MMI) power splitters for low
insertion loss and wide bandwidth from 1200 to 1650 nm wavelength
range. By using A-DDQN to guide hole etchings in the interference
region of MMI, the target splitting ratio (SR) can be obtained with
much less CPU time (about 10 hours for one design) and more effective
utilization of the computational resources in asynchronous/parallel
manner. Also, this method can simplify the design by using relatively
few holes to obtain the same SR with small return loss.

Background

There is an increasing use of cesarean delivery (CD) based on preference rather than on medical indication. However, the extent to which nonmedically indicated CD benefits or harms child survival remains unclear. Our hypothesis was that in groups with a low indication for CD, this procedure would be associated with higher child mortality and in groups with a clear medical indication CD would be associated with improved child survival chances.

Methods and findings

We conducted a population-based cohort study in Brazil by linking routine data on live births between January 1, 2012 and December 31, 2018 and assessing mortality up to 5 years of age. Women with a live birth who contributed records during this period were classified into one of 10 Robson groups based on their pregnancy and delivery characteristics. We used propensity scores to match CD with vaginal deliveries (1:1) and prelabor CD with unscheduled CD (1:1) and estimated associations with child mortality using Cox regressions. A total of 17,838,115 live births were analyzed. After propensity score matching (PSM), we found that live births to women in groups with low expected frequencies of CD (Robson groups 1 to 4) had a higher death rate up to age 5 years if they were born via CD compared with vaginal deliveries (HR = 1.25, 95% CI: 1.22 to 1.28; p < 0.001). The relative rate was greatest in the neonatal period (HR = 1.39, 95% CI: 1.34 to 1.45; p < 0.001). There was no difference in mortality rate when comparing offspring born by a prelabor CD to those born by unscheduled CD. For the live births to women with a CD in a prior pregnancy (Robson group 5), the relative rates for child mortality were similar for those born by CD compared with vaginal deliveries (HR = 1.05, 95% CI: 1.00 to 1.10; p = 0.024). In contrast, for live births to women in groups with high expected rates of CD (Robson groups 6 to 10), the child mortality rate was lower for CD than for vaginal deliveries (HR = 0.90, 95% CI: 0.89 to 0.91; p < 0.001), particularly in the neonatal period (HR = 0.84, 95% CI: 0.83 to 0.85; p < 0.001). Our results should be interpreted with caution in clinical practice, since relevant clinical data on CD indication were not available.

Conclusions

In this study, we observed that in Robson groups with low expected frequencies of CD, this procedure was associated with a 25% increase in child mortality. However, in groups with high expected frequencies of CD, the findings suggest that clinically indicated CD is associated with a reduction in child mortality.

Published: October 2021

Papaya ringspot virus biotype-P is a detrimental pathogen of economically important papaya and cucurbits worldwide. The mutation prone feature of this virus perhaps accounts for its geographical dissemination. In this study, investigations of the atypical PRSV-P strain was conducted based on phylogenetic, recombination and genetic differentiation analyses considering of it’s likely spread across India and Bangladesh. Full length genomic sequences of 38 PRSV isolates and 35 CP gene sequences were subjected to recombination analysis. A total of 61 recombination events were detected in aligned complete PRSV genome sequences. 3 events were detected in complete genome of PRSV strain PK whereas one was in its CP gene sequence. The PRSV-PK appeared to be recombinant of a major parent from Bangladesh. However, the genetic differentiation based on full length genomic sequences revealed less frequent gene flow between virus PRSV-PK and the population from America, India, Colombia, other Asian Countries and Australia. Whereas, frequent gene flow exists between Pakistan and Bangladesh virus populations. These results provided evidence correlating geographical position and genetic distances. We speculate that the genetic variations and evolutionary dynamics of this virus may challenge the resistance developed in papaya against PRSV and give rise to virus lineage because of its atypical emergence where geographic spread is already occurring.
Psychological, social and cognitive resources and the mental wellbeing of the poor
Authors: Cobb-Clark Deborah A. , Kettlewell Nathan
Published: October 2021

Our study takes advantage of unique data to quantify deficits in the psychosocial and cognitive resources of an extremely vulnerable subpopulation–those experiencing housing vulnerability–in an advanced, high-income country (Australia). Groups such as these are often impossible to study using nationally representative data sources because they make up a small share of the overall population. We show that those experiencing housing vulnerability sleep less well, have more limited cognitive functioning, and less social capital than do those in the general population. They are also less emotionally stable, less conscientious, more external, and more risk tolerant. Collectively, these deficits in psychosocial and cognitive resources account for between 24–42% of their reduced life satisfaction and their increased mental distress and loneliness. These traits also account for a large proportion of the gap in mental wellbeing across different levels of housing vulnerability.
‘No, YOU make it!’: Outsourcing production to fashion consumers to mediate labour
Authors: Øien Ida Falck , Zanon Johanna
Published: October 2021

This practice-based article examines an attempt to reconnect fashion labour with value, after the fast fashion system increased the gap between the two. Developed by Norwegian fashion brand and collective platform HAiKw/ (Harald Lunde Helgesen and Ida Falck Øien), the Drop-in
Factory was a fashion design experiment conducted at the non-profit art space Kunsthall Oslo in 2019. In this experiment, labour was outsourced to consumers-visitors, who by contract paid for equipment rental and training, earning ‘Factory Coins’ that could only be spent on
the finished product. Inviting amateurs to make their own garment in a workshop setting has become a common strategy of design activism in fashion. However, instead of focusing on teaching individuals craft expertise, the Drop-in Factory explored collective making practices in an industrial-like
environment, inspired by manufacturing and scientific management. Tensions arose over pay when some participants felt that their labour was unfairly compensated. As a response, roleplaying emerged from the experiment. Interviews of participants, conducted months later, incidentally echoed
roleplay debriefing sessions. Their accounts show that they acquired labour literacy and embodied knowledge of fashion manufacturing, which extended to contracts and remuneration. While it remains unclear whether the Drop-in Factory led participants to revalue fashion labour, audience
participation itself became the mediation of fashion labour.
Pathological Response Rate of Paclitaxel Based Dose Dense and Conventional Neoadjuvant Chemotherapy in Locally Advanced Female Breast Cancer Patients
Authors: Chellappan Nonam , Raj Smitha G.
Published: October 2021

BACKGROUND Locally advanced female breast cancer patients have the highest risk of recurrence and distant metastasis. Taxane-based neoadjuvant chemotherapy gives a more pathological response. The purpose of this study was to assess the pathological response rate of paclitaxel-based dose-dense and conventional neoadjuvant chemotherapy in locally advanced female breast cancer patients. METHODS In this observational study, a total of hundred locally advanced female breast cancer patients were randomly selected for neoadjuvant chemotherapy. Fifty patients received three weekly paclitaxel 200 mg/m2 (4 courses) and other fifty patients received weekly paclitaxel 80 mg/m2 (10 courses) along with three weekly doxorubicin 50 mg/m2(4 courses in both arms). Chemotherapy-induced clinical response in both arms was weekly assessed by tumour and lymph node size measurements, change in consistency and fixity. Pathological response of chemotherapy in each arm was assessed by taking the difference of mean tumour volumes and presence of chemotherapy-induced fibrosis and collections of histiocytes in lymph nodes. RESULTS There was statistically significant pathological reduction after neoadjuvant chemotherapy was seen in three weekly arms (68.18 cm3 to 37.22 cm3 P-value 0.000), in the weekly arm (68.42 cm3 to 18.04 cm3 P-value 0.000) and difference in reduction of tumour volume (more in weekly arm -50.38 cm3 versus 30.86 cm3, Pvalue 0.000). CONCLUSIONS Locally advanced female breast cancer patients receiving neoadjuvant chemotherapy with paclitaxel showed a better pathological response rate. It was more in the weekly paclitaxel arm.

Published: October 2021

BACKGROUND Magnetic resonance imaging (MRI) provides structural characterization of brain lesions, by measuring volume of axial, sagittal and coronal planes through two dimensional slices. The purpose of this study was to characterize and identify the orthogonal imaging planes to detect non tumour lesions of brain through MRI. METHODS This study included 81 patients, both males and females, suspected of brain lesions and underwent MRI for diagnosis. The variations in the volume of the anatomical structures were measured and compared the planes as axial and sagittal, axial and coronal and coronal and sagittal for non-tumour brain lesions. RESULTS The present study revealed the differences in the measurement of volume in nontumour lesions (N = 81) in axial, sagittal and coronal planes. It was found that the volume of axial planes (9.2) is more dominant than the sagittal (9.1) and coronal planes (8.8) in non-tumour lesions. Statistical analysis was done by Statistical Package for Social Sciences (SPSS version 16 software). Two way/Friedman test were used for comparing the three groups. CONCLUSIONS This study concluded that, in most of the brain lesions irrespective of the type of tumours, axial planes helps more in the detection of tumour volume as compared to sagittal and coronal planes for precise diagnosis of brain lesions.

Self-Perceived Loneliness and Depression During the COVID-19 Pandemic: a Two-Wave Replication Study
Authors: Carollo Alessandro , Bizzego Andrea , Gabrieli Giulio , Wong Keri Ka-Yee , Raine Adrian , Esposito Gianluca
Published: October 2021

COVID-19 studies to date have documented some of the initial health consequences of lockdown restrictions adopted by many countries. Combining a data-driven machine learning paradigm and a statistical analysis approach, our previous paper documented a U-shape pattern in levels of self-perceived loneliness in both the UK and Greek populations during the first lockdown (17 April to 17 July 2020). The current paper aimed to test the robustness of these results. Specifically, we tested a) for the dependence of the chosen model by adopting a new one - namely, support vector regressor (SVR). Furthermore, b) whether the patterns of self-perceived loneliness found in data from the first UK national lockdown could be generalizable to the second wave of the UK lockdown (17 October 2020 to 31 January 2021). The first part of the study involved training an SVR model on the 75% of the UK dataset from wave 1 (n total = 435). This SVR model was then tested on the remaining 25% of data (MSE training = 2.04; MSE test = 2.29), which resulted in depressive symptoms to be the most important variable - followed by self-perceived loneliness. Statistical analysis of depressive symptoms by week of lockdown resulted in a significant U-shape pattern between week 3 to 7 of lockdown. In the second part of the study, data from wave 2 of the UK lockdown (n = 263) was used to conduct a graphical and statistical inspection of the week-by-week distribution of scores regarding self-perceived loneliness. Despite a graphical U-shaped pattern between week 3 and 9 of lockdown, levels of loneliness were not between weeks of lockdown. Consistent with past studies, study findings suggest that self-perceived loneliness and depressive symptoms may be two of the most relevant symptoms to address when imposing lockdown restrictions.

The study was conducted to evaluate the epidemiological of toxoplasma gondii in local cows in Salah Adeen, and its effect to renal and liver function. One hundred twenty six sample of serum were collected from cows n different cows farm in Salah Adeen, include Samarra (60 sample), Al-Mutasim (28 sample), Baled (23 sample) and Aldejil (15 sample), from the period between July 2019 until February 2020. The study include detection of serum anti T. gondii IgG antibody by using ELISA Toxoplasma IgG kit, and also determination of serum liver enzymes activity which include (Transaminases enzymes: aspartate transaminase-AST and alanine transaminase-ALT) and also the concentration of serum total protein-TP, albumin, globulin, urea and creatinine. The results indicate that the total percentage for the prevalence of T.gondii between cows in Saleh Eldean was 51.58%, distributed according to the region (68.33% in Samarra, 50% in Al-Mutasim, 26.08% in Baled and 26.66 in Aldejil). While the total percentage for infection with the parasite according to the gender of animals were 58.33% (28 from 48) in male animal and 47.43% (37from 78) in female animal. The results also showed that the level of TP, Albumin, globulin were significantly higher P≤0.05 in sera of infected animals, and also the activity of liver enzymes (AST and ALT) were significantly higher P≤0.05 in sera of infected animals with T.gondii with no significant difference in the level of urea and creatinine in sera of infected group as compared with non-infected group as control group. From all the above results we can conclude that the prevalence of T. gondii was high among animal under investigation, and this infection may be effect to the physiological function especially liver function.

In this work, two elements were developed. The first is Multi walled carbon nanotubes-zinc phthalocyanine (ZnPcs). In addition, there was also a development of the multi walled carbon nanotubes-aluminium phthalocyanine hybrid materials. The multi-walled carbon nanotubes were under treated with nitric combined with the sulfuric acid before being mixed with phthalocyanines to de-build the effects. Drop-casting hybrid materials to slides of the glass and interdigitating electrodes from their dimethylformamide solution have been done. The perfect hybridization owing to π-π interaction was discovered. This discovery was assisted by two elements. The first is the ultraviolet-visible absorption spectroscopy. Moreover, another element that played a vital role in this discovery is Fourier Transform Infrared Spectroscopy. The hybrid films were tested for current-voltage measurements and direct electrical conductivity. This work has also examined how temperature affects direct electrical conductivity and power generation.

Argument quality has become an important variable that promotes consumers’ decision-making based on online reviews. It has two dimensions, perceived informativeness and perceived persuasiveness. Adopting dual-process theory, this study examines the effect of these two dimensions of argument quality on review adoption. Moreover, it investigates whether the relationships between argument quality and review adoption differ based on product type and review type. According to the multi-group analysis result, for attribute-centric reviews, search products have a better fit than experience products in the relationship of perceived informativeness and perceived persuasiveness, also for the relationship of perceived informativeness on review adoption, while experience products have a better fit than search products for the relationship of perceived persuasiveness on review adoption. For benefitcentric reviews, search products and experience products have no significant difference in any of the relationships. Furthermore, the result reveals that perceived persuasiveness mediates perceived informativeness and review adoption. The findings contribute to the understanding of the information adoption model with different review types and product types and help shopping websites develop better strategies for product recommendation reviews.

This study aims to study the relationship between personality traits (conscientiousness and extraversion), electronic performance monitoring (EPM) and work passion. In addition, it investigates the mediating role of EPM between personality traits and work passion. Data was collected from 105 employees working in call centers throughout Pakistan. Partial least squares structural equation modeling (PLS-SEM), using SmartPLS 3.0, was performed to test the hypothesized model. The results showed that consciousness and extraversion have a positive impact on EPM and work passion. In addition, EPM acts significantly as a mediator between personality traits and work passion among call center employees. This is the first study that examines the mediating role of EPM in the relation between personality differences and work passion. The results of the study would help Asian human resources professionals effectively perform human resources functions, such as employee staffing, training, and performance management. Implications for managers and recommendations for future studies are proposed.
