Published: June 2024

Aims: The purpose of this study was to determine the effect of product quality, service quality and electronic word of mouth on repurchase intentions by mediating customer satisfaction on Erigo products in the shopee marketplace in Malang City.
Study Design: This research uses a descriptive quantitative approach.
Place of Study: Respondents in this study were Erigo consumers who had bought at least 2 times, had a shopee platform and the age of consumers was at least 17 in Malang City.
Methodology: The sampling method applied is nonprobability sampling, specifically through purposive sampling technique. A total of 154 respondents were selected using purposive sampling technique. The data was processed with version 4.0 of smartPLS.
Results: All elements in the statement are legitimate, according to the validity test findings. Furthermore, the results of the hypothesis test show that product quality does not influence the desire to repurchase (P Values 0.362>). P Values 0.002 indicate that service quality influences repurchase intentions, whereas P Values 0.751 indicate that electronic word of mouth does not influence repurchase intentions. 0.05. The following conclusions can be drawn: - Repurchase intention is influenced by customer satisfaction (P Values 0.000 <0.05), which in turn is influenced by product quality (P Values 0.002 <0.05), service quality (P Values 0.005 <0.05), and electronic word of mouth (P Values 0.080 <0.05). - Repurchase intentions are influenced by product quality (P Values 0.002 <0.05), which is mediated by customer satisfaction (P Values 0.007 <0.05), and by electronic word of mouth (P Values 0.077>), which is mediated by customer satisfaction (P Values 0.080 <0.05), which in turn affects repurchase intentions (0.5). 0.05.
Conclusion: Product quality affects customer happiness but has little effect on their propensity to buy again. The quality of service has an effect on customer satisfaction and their propensity to make a repeat purchase. Online recommendations have little effect on consumers' happiness or propensity to buy again. The quality of the product or service does influence the likelihood that a consumer will make a repeat purchase, but the impact of electronic word of mouth on consumer satisfaction is minimal.

Aim: The contamination of soil and vegetables by heavy metals is a critical environmental and public health issue, particularly in regions where wastewater is utilized for irrigation. This study assesses the concentration of heavy metals, (Cr, Zn, Cd, Fe, Mn, Ni, Pb, As, Co and Cu) accumulated in soils and vegetables grown in Peri-urban areas which are mainly irrigated with wastewater.
Place and Duration of Study: This study was conducted in Department of Soil Science and Agricultural Chemistry, JNKVV, Jabalpur, Madhya Pradesh during 2022-23.
Methodology: Heavy metal content was measured using an Inductively coupled plasma-Mass Spectroscopy. Few indices for human health were also studied. Ten sites were chosen for soil and plant samples for analysis of metal content.
Results: The study revealed that the metal content of soil samples were below the permissible limits except for soil collected from Khandari site which had Co above the permissible level (203.65 mg/kg) and slightly Cd contamination in Khurji site (0.09 mg/kg). In case of vegetables, brinjal collected from Regama and Kumhi site showed Fe and Cd contamination (735.67 mg/kg, 476.33 mg/kg) and (0.35 mg/kg, 0.34 mg/kg), respectively. Potato and cabbage collected from Khurji and Khandari sites showed Fe contamination of 455.67 mg/kg and 670.83 mg/kg, respectively. Further the result on transfer factor for vegetables was <1, except potato collected from Khandari site which had Cd accumulated in edible portion (11.70). Wheat crop collected from Khurji site also had Cd accumulated (24.66) in grain portion.
Conclusion: Despite few vegetables showed contamination by metals, health risk parameters viz Daily intake of metals, Health risk index and Metal pollution index but were found at safe levels. Thus, it can be concluded that there was no apparent risk for human beings after consumption in Peri-urban regions of Jabalpur district. Still to ensure quality of soil, vegetables and human health measures should be taken to regulate and address pollution of heavy metals in peri-urban areas.

Published: June 2024

The influence of rootstocks on yield, berry and wine quality and sensory evaluation of Sauvignon Blanc was studied during 2017-2020 on 7-year-old vines of Sauvignon Blanc at ICAR-National Research Centre for Grapes, Pune, India. The vines grafted on seven different rootstocks (Dogridge, Salt Creek, Fercal, 140Ru, SO4, 1103P and 110R) were used for study. The yield and berry quality parameters viz., number of bunches/vine and yield per vine varied significantly among the rootstocks. The vines grafted on Salt Creek rootstock recorded maximum average bunch weight (138.23 gm) while, higher number of bunches/vine (52.73) and yield/vine (7.11 kg) was recorded in 110R grafted vines. TSS content in berries was higher (24.240B) and lowest acidity (0.56 g/L) in Dogridge rootstock grafted vines. Wine composition parameters like glucose (2.71 g/l), malic acid (3.3 g/l) and total acid (7.30 g/l) was higher in 140Ru rootstock; volatile acid (0.54 g/l) and pH (3.60) of wine was higher in110R rootstock. The ethanol (14.04 %) in wine was higher in vines grafted on SO4 rootstock. The wine sensory attributes were also positively influenced using different rootstocks, wine prepared from Sauvignon Blanc grapes grafted on Fercal rated the highest overall wine quality followed by 110R and Dogridge rootstocks.
Neighborhood disadvantage, individual‐level socioeconomic position, and self‐reported chronic arthritis: A cross‐sectional multilevel study
Authors: Brennan S. L. , Turrell G. 
Published: January 2012

AbstractObjectiveTo examine the association between individual‐ and neighborhood‐level disadvantage and self‐reported arthritis.MethodsWe used data from a population‐based cross‐sectional study conducted in 2007 among 10,757 men and women ages 40–65 years, selected from 200 neighborhoods in Brisbane, Queensland, Australia using a stratified 2‐stage cluster design. Data were collected using a mail survey (68.5% response). Neighborhood disadvantage was measured using a census‐based composite index, and individual disadvantage was measured using self‐reported education, household income, and occupation. Arthritis was indicated by self‐report. Data were analyzed using multilevel modeling.ResultsThe overall rate of self‐reported arthritis was 23% (95% confidence interval [95% CI] 22–24). After adjustment for sociodemographic factors, arthritis prevalence was greatest for women (odds ratio [OR] 1.5, 95% CI 1.4–1.7) and in those ages 60–65 years (OR 4.4, 95% CI 3.7–5.2), those with a diploma/associate diploma (OR 1.3, 95% CI 1.1–1.6), those who were permanently unable to work (OR 4.0, 95% CI 3.1–5.3), and those with a household income <$25,999 (OR 2.1, 95% CI 1.7–2.6). Independent of individual‐level factors, residents of the most disadvantaged neighborhoods were 42% (OR 1.4, 95% CI 1.2–1.7) more likely than those in the least disadvantaged neighborhoods to self‐report arthritis. Cross‐level interactions between neighborhood disadvantage and education, occupation, and household income were not significant.ConclusionArthritis prevalence is greater in more socially disadvantaged neighborhoods. These are the first multilevel data to examine the relationship between individual‐ and neighborhood‐level disadvantage upon arthritis and have important implications for policy, health promotion, and other intervention strategies designed to reduce the rates of arthritis, indicating that intervention efforts may need to focus on both people and places.

AbstractObjectiveTo investigate the passive properties of the plantar flexors muscle–tendon tissue in patients with the hypermobility type of Ehlers‐Danlos syndrome (EDS‐HT).MethodsTwenty‐five women with EDS‐HT and 25 sex‐ and age‐matched healthy control subjects participated in the study. Passive resistive torque (PRT) of the plantar flexors was measured with an isokinetic dynamometer during 2 standardized stretch protocols to obtain the passive muscle tension. Protocol 1 consisted of 4 continuous cycles to a predetermined angle of 10° dorsiflexion. Protocol 2 consisted of a slow stretch to the onset of pain. Torque, angle, and electromyography were simultaneously recorded during the tests. To take muscle thickness into account, muscle cross‐sectional area (MCSA) was obtained with peripheral quantitative computed tomography. Stiffness of the Achilles tendon was assessed using a dynamometer in combination with ultrasonography.ResultsThe results demonstrate a significantly larger maximal joint angle in the EDS‐HT patients accompanied by a similar PRT compared to the control subjects (protocol 2), indicating a lower passive muscle tension in the patient group. PRT for the predetermined angle (protocol 1) was the same for both groups and there was no difference in MSCA. Furthermore, a significantly lower Achilles tendon stiffness was seen in the patient group than in the control group.ConclusionThis study is the first to provide evidence for altered passive properties of the muscle–tendon unit in EDS‐HT patients. These changes are thought to be associated with structural modifications in connective tissue.

AbstractObjectiveTo develop a clinical risk prediction tool to identify patients most likely to experience long‐term clinically meaningful functional improvement following total hip arthroplasty (THA).MethodsWe studied 282 patients from 2 health districts in England (Portsmouth and North Staffordshire) who were ≥45 years of age and undergoing THA for primary osteoarthritis. Baseline data on age, sex, comorbidity, body mass index (BMI), functional status (Short Form 36 [SF‐36]), and preoperative radiographic severity were collected by interview and examination. The outcome was a clinically significant (30‐point) improvement in SF‐36 physical function score assessed ∼8 years after THA. Logistic regression modeling was used to identify predictors of functional improvement.ResultsImprovement in physical function was less likely in patients with better preoperative functioning (odds ratio [OR] 0.73 [95% confidence interval (95% CI) 0.60, 0.89]), older people (OR 0.94 [95% CI 0.90, 0.98]), women (OR 0.37 [95% CI 0.19, 0.72]), those with a previous hip injury (OR 0.14 [95% CI 0.03, 0.74]), and those with a greater number of painful joint sites (OR 0.61 [95% CI 0.46, 0.80]). Patients with worse radiographic grades were most likely to improve (OR 2.15 [95% CI 1.17, 3.93]). We found no influence of BMI or patient comorbidity on functional outcome. Predictors of good outcomes were the same as those of bad outcomes, acting in the opposite direction. A clinical risk prediction tool was developed to identify patients who are most likely to receive functional improvement following THA.ConclusionThis prediction tool has the potential to inform health care professionals and patients about functional improvement following THA (as distinct from driving rationing or commissioning decisions regarding who should have surgery); it requires introduction into clinical practice under research conditions to investigate its impact on decisions made by patients and clinicians.

Published: January 2012

AbstractObjectiveThere are sparse data on outcome of lupus nephritis from developing countries. This study looks at outcome in Asian Indians.MethodsThis retrospective study included patients at a single center over 20 years. Patients were treated as per standard protocols. The primary outcome measure was chronic renal failure or death; the secondary outcome was end‐stage renal disease or death. The worst‐case scenario was also calculated, considering those lost to followup in the first year as events. Kaplan‐Meier survival curves and the log rank test were used for survival analysis. Data are shown as the mean ± SD.ResultsWe included 188 patients with lupus nephritis, with a female:male ratio of 11:1, a mean ± SD age at onset of 23.6 ± 10.5 years, and a median followup time of 6 years (interquartile range 3–9 years). Of 136 patients with a biopsy sample, the distribution was as follows: class II in 22, class III in 36, class IV in 61, class V in 16, and class VI in 1. Survival with normal renal function was 84%, 69%, and 57% at 5, 10, and 15 years, respectively; in the worst‐case scenario, survival was 77%, 63%, and 51%, respectively. There was no difference in survival by histologic class; however, nonbiopsied patients had lower survival. Renal survival was 91%, 81%, and 76% at 5, 10, and 15 years, respectively; in the worst‐case scenario, survival was 79%, 70%, and 66%, respectively. Risk factors for poor outcome were low C3, hematuria, hypertension, creatinine, lack of remission, and occurrence of major infection. There was a high rate of major infections of 42.3%, with tuberculosis at 11.5%. Infections caused one‐half of all deaths.ConclusionThe outcome of lupus nephritis in Asian Indians with standard immunosuppressive regimens is reasonable, but immunosuppression is associated with a high rate of infection.
Predicting future response to certolizumab pegol in rheumatoid arthritis patients: Features at 12 weeks associated with low disease activity at 1 year

Published: January 2012

AbstractObjectiveTo determine the prognostic significance of data collected early after starting certolizumab pegol (CZP) to predict low disease activity (LDA) at week 52.MethodsData from 703 CZP‐treated patients in the Rheumatoid Arthritis Prevention of Structural Damage 1 (RAPID 1) trial through week 12 were used as variables to predict LDA (Disease Activity Score in 28 joints–erythrocyte sedimentation rate ≤3.2) at week 52. We identified variables, developed prediction models using classification trees, and tested performance using training and testing data sets. Additional prediction models were constructed using the Clinical Disease Activity Index (CDAI) and an alternate outcome definition (composite of LDA or American College of Rheumatology criteria for 50% improvement [ACR50]).ResultsUsing week 6 and 12 data and across several different prediction models, response (LDA) and nonresponse at 1 year were predicted with relatively high accuracy (70–90%) for most patients. The best performing model predicting nonresponse by 12 weeks was 90% accurate and applied to 46% of the population. Model accuracy for predicted responders (30% of the RAPID 1 population) was 74%. The area under the receiver operating curve was 0.76. Depending on the desired certainty of prediction at 12 weeks, ∼12–25% of patients required >12 weeks of treatment to be accurately classified. CDAI‐based models and those evaluating the composite outcome (LDA or ACR50) achieved comparable accuracy.ConclusionWe could accurately predict within 12 weeks of starting CZP whether most established rheumatoid arthritis (RA) patients with high baseline disease activity would likely achieve/not achieve LDA at 1 year. Decision trees may be useful to guide prospective management for RA patients treated with CZP and other biologics.
Prediction of Fatigue Lives of MAR‐M247 LC Based on the Crack Closure Concept
Authors: Gelmedin Domnin , Lang Karl‐Heinz , Newman James C. 
Published: January 2012

AbstractLow cycle fatigue (LCF), high cycle fatigue (HCF), and combined LCF and HCF tests are carried out on MAR‐M247 LC at 650 °C in air environment. Under combined LCF and HCF loading, block striations form on the fracture surface which are used to complete an effective crack growth curve by using the linear summation model. Crack growth lives starting from equivalent initial flaw sizes are calculated by the crack closure code FASTRAN and compared with experimental fatigue lives. Under HCF loading, predicted and experimental fatigue lives agree well for lifetimes above 105 cycles. Lower lifetimes are overestimated indicating that the linear summation model is not valid for MAR‐M247 LC in this loading range. Interactions between the non‐crystallographic HCF crack growth and striated crack growth that is caused by the LCF loading are probably responsible for this behavior.

AbstractCore–shell Ag@Au nanoprisms are prepared through a surfactant‐free seed‐mediated approach by taking advantage of the anisotropic structure of silver nanoprisms as seeds. The gold coating on the silver nanoprism surface is achieved by using hydroxylamine as a mild reducing agent, and the final fully gold‐coated prism structures are confirmed by microscopic and spectroscopic characterization. The resulting Ag@Au core–shell structure preserves the optical signatures of nanoprisms and offers versatile functionality and particularly better stability against oxidation than the bare silver nanoprism. The surface plasmon resonances of the core–shell Ag@Au nanoprisms can be tuned throughout the visible and near‐IR range as a function of the Au shell thickness. Such tailorable optical features and surfactant‐free gold shells have great potential applications in biosensing and bioimaging.
Perylene Imides for Organic Photovoltaics: Yesterday, Today, and Tomorrow
Authors: Li Chen , Wonneberger Henrike 
Published: January 2012

AbstractPerylene imides have been an object of research for 100 years and their derivatives are key n‐type semiconductors in the field of organic electronics. While perylene diimides have been applied in many electronic and photonic devices, their use can be traced back to the first efficient organic solar cell. By functionalizing different positions of the in total 12 positions (four peri, four bay, and four ortho‐positions) on the perylene core, perylene imides with significantly different optical, electronic and morphological properties may be prepared. Perylene imides and their derivatives have been used in several types of organic photovoltaics, including flat‐, and bulk‐heterojunction devices as well as dye‐sensitized solar cells. Additionally perylene imides‐based copolymers or oligomers play an important role in single junction devices. In this review, the relationship between the photovoltaic performance and the structure of perylene imides is discussed.

AbstractObjectiveMutations in LMNA encoding the A‐type lamins cause several diseases, including those with features of premature aging and skeletal abnormalities. The aim of this study was to examine the expression of lamin A in cartilage from patients with osteoarthritis (OA) and the effects of its overexpression on chondrocyte senescence and apoptosis.MethodsHuman chondrocyte‐like cells (SW‐1353) were used. RNA isolated from human OA and non‐OA cartilage was used for profiling messenger RNA expression, using Affymetrix microarray analysis. The effects of lamin A overexpression on mitochondrial function and apoptosis were examined by assessing mitochondrial membrane potential, ATP levels, and cytochrome c release, and with a TUNEL assay. Western blotting was performed to determine protein expression.ResultsLamin A expression was markedly elevated in OA cartilage samples compared with non‐OA control samples. Western blot analysis confirmed increased expression of lamin A in OA compared with non‐OA cartilage. Interleukin‐1β treatment inhibited lamin A accumulation, whereas treatment with prostaglandin E2 (PGE2) caused a marked increase in lamin A accumulation. These effects of exogenous PGE2 on lamin A expression were mediated via the EP2/EP4 receptors. Transfected chondrocytes that expressed lamin A displayed markers of early senescence/apoptosis.ConclusionThe results of this study suggest that lamin A is up‐regulated in OA chondrocytes, and that increased nuclear accumulation of lamin A in response to catabolic stress may account for the premature aging phenotype and apoptosis of OA chondrocytes.
