Mechanical-Biological Treatment of Mixed Municipal Solid Waste: Two Plants in Bengaluru, India
Authors: Mohanta Tandra , Goel Sudha
Published: April 2021

In recent times, there have been an enormous increase in the number and capacity of mechanical–biological treatment (MBT) plants all over the world owing to the need for finding sustainable solutions to the mixed municipal solid waste (MSW) problem. The objective of this study was to understand the technical and financial aspects of two MBT plants located in Bengaluru, India. Both plants treat mixed MSW. Of the two plants in Bengaluru, only one is financially stable and operating since 1975. The major product generated by this plant is compost. The second one was started in 2015 and closed after a year of operation. It was generating refuse-derived fuel (RdF) and compost. Compost and RdF generated by these MBT plants have limited market acceptance. Major challenges faced by both MBT plants in Bengaluru are untrained human resources, limited market demand for their products, budgetary constraints, inadequate infrastructure and unreliable MSW generation and composition data.

Published: April 2021

An intensive increase in the area of clear-cutting on the territory of Russia leads to the growth of non-reforested areas. Therefore, successful reforestation requires higher attention and the use of new technological solutions for growing seedlings. The purpose of this work was to perform an economic assessment of the costs required for traditional and innovative technologies in growing seedlings of woody species with open and closed root systems under different cultivation conditions. The results of the comparative analysis showed that seedlings grown with closed root systems without heating in greenhouses in one rotation require minimum costs for growing. An increasing number of rotations in growing seedlings with closed root systems leads to a decrease in the production costs and makes seedlings of English oak competitive in price with seedlings grown by traditional technology. It has been established that the discounted ROI period for seedlings with a closed root system is 5.5 years. Hence, the transition to innovative technologies for the cultivation of forest planting material is necessary for the effective implementation of recreation processes for forestry of Russia.
Irrigation Recommendation for Water Saving and Salinity Control in Horticulture in the Semi-arid Lower Cheliff Plain (Algeria)
Authors: Abdelkrim Noureddine , Hartani Tarik , Visconti Fernando , De Paz José Miguel , Douaoui Abdelkader
Published: April 2021

Salinity and water deficit are two major issues for agricultural development in Algeria. The Lower Cheliff plain, northwestern Algeria, is, furthermore, characterised by semi-arid Mediterranean climate, and soils with high clay content. Our study area was a 4 ha farm located in Oued Rhiou and another 1 ha farm located in Ouarizane, both upstream in the Lower Cheliff plain, and irrigated with waters of different salinities: 1.8 and 5.5 dS m-1, respectively. The plots were equipped with drip irrigation and subsurface drainage systems. Farmer’s irrigation management of artichoke and melon were observed during the respective cropping seasons from September 2010 till June 2011, and from April till July 2011. The total irrigation amounts were, respectively, 364 mm and 240 mm, while the precipitations were 367 mm and 67 mm. The soil properties were determined in the entire rooting depths down to 80 cm for artichoke and 60 cm for melon. In addition to these, irrigation water composition, and crop development parameters were used to simulate soil salinity using the SALTIRSOIL_M model. Simulations and observations of soil pH, main ion concentrations and ECe showed reasonable agreements for June 2011. Next, the irrigation schedules that would have met the water needs of both crops, while simultaneously keeping soil salinity below harmful levels were estimated using the model. For the artichoke plot, a lower irrigation rate (290 mm yr-1) could have kept water deficit and soil salinity below their respective harmful thresholds. For the melon plot, on the contrary, a higher irrigation rate (480 mm yr-1) is able to neutralise the water deficit, though not completely the salinity stress would have been adequate. Farmers’ irrigation practices in the context of the climate, water quality and soil properties of the Lower Cheliff plain can be analysed and improved with the aid of soil salinity modelling.
Physical and Chemical Quality Boundaries of Ground Water in Kanchipuram District of Tamil Nadu, India
Authors: Hamideen Mefleh S. , Chandrasekaran Ananthanarayanan
Published: April 2021

Water is fundamental for all living life forms for their living and metabolic cycles. The purpose of the current investigation is to gauge a few water quality boundaries in the Kanchipuram region of Tamil Nadu, India and dissect the information by multivariate statistical methods. So as to evaluate the ground water quality, boundaries, for example, pH, total dissolved solids (TDS), electrical conductivity (EC), chloride (Cl), sulphate (SO4), calcium (Ca), magnesium (Mg), nitrate (NO3), sodium (Na), potassium (K), carbonate (CO3) and hydrogen carbonate (HCO3) were resolved utilising distinctive systematic techniques. The after effects of physicochemical properties were contrasted and recommended limits given by WHO (2004) and BIS (2012). The acquired outcome uncovers that the decided water quality boundaries are not exactly as far as possible. Measurable methods, for example, Pearson connection, principal and cluster examinations were applied among the ground water information to consider the relation between them.
Aquifer (Hydrogeological) Study of Southern Areas of Prayagraj, India
Authors: Dwivedi Brajesh K.
Published: April 2021

The physical and chemical characteristics of spring and well water samples were studied for two years to assess the origin of groundwater and determine the factors driving the geochemical composition. The ionic speciation and mineral dissolution/precipitation were calculated. Water wells, characterising groundwater circulation at shallow depths are moderate to high mineralised waters of Na-HCO3 type. In contrast to the shallow environment, the CO2-rich, deeper water is of the Ca-HCO3-SO4 type and undergoes significant changes in the baseline chemistry along flow lines with increasing residence time. The main factors controlling the groundwater composition and its seasonal variations are the geology, because of the presence of carbonate formations, the elevation and the rate of karst development. In both groups, the carbonate chemistry was a diagnostic approach. The super-saturation with respect to calcite indicates CO2 degassing, occurring either inside the aquifer in open conduits or at the outlet in reservoirs. Interaction between groundwater and surrounding rocks is believed to be the main process responsible for the observed chemical characteristics of groundwater in the study area. Mathematical equations were also derived involving the hydro geological variables for better prediction of the aquifer.

Published: April 2021

BACKGROUND:

EAU guidelines recommend a single instillation (SI) of intravesical chemotherapy (e.g. Mitomycin C) within 24 hours after transurethral resection of a bladder tumour (TURBT) in patients with low- to intermediate risk non-muscle invasive bladder cancer without (suspected) bladder perforation or bleeding requiring bladder irrigation. However, remarkable variation exists in the use of SI. The risk of severe complications is likely to contribute to this variation, but evidence is limited.

OBJECTIVE:

To investigate the absolute severe complication and mortality risk after SI in low- and intermediate risk bladder cancer.

METHODS:

In this observational, historic cohort study, data on 25,567 patients diagnosed with TaG1G2 urothelial bladder carcinoma (UBC) between 2009 and 2018 who underwent TURBT were collected from the Netherlands Cancer Registry. Data were supplemented with information on cause of death and severe complications after cancer treatment by re-examining the electronic health records and the 14-day complication risk and the 30-day mortality risk were evaluated.

RESULTS:

On average, 55% of patients had a SI after TURBT, varying from 0–>80% between hospitals. The 30-day mortality risk was 0.02% and the 14-day risk of severe complications was 1.6%.

CONCLUSIONS:

As the absolute risk of mortality and severe complications is very low, SI after TURBT can be considered a safe treatment in patients with low- to intermediate UBC without contraindications for SI. These results imply that a part of eligible patients is denied effective treatment.
Effect of cerebrolysin on neurodevelopmental outcome of high risk preterm infants: A randomized controlled trial
Authors: Samir A. , Nasef N. , Fathy K. , El-Gilany A-H. , Yahia S.
Published: April 2021

BACKGROUND:

A significant proportion of preterm infants experience developmental delay despite receiving a post discharge early interventional care. Cerebrolysin is a peptide mixture which acts similar to endogenous neurotrophic factors through promoting neurogenesis and enhancing neuronal plasticity.

OBJECTIVE:

To compare the effect of Cerebrolysin plus routine intervention program versus routine intervention program alone on the outcome of preterm infants at high risk for neurodevelopmental delay.

METHODS:

In a randomized controlled trial, high-risk preterm infants < 32 weeks’ gestation who have abnormal neurological assessment at two months corrected post-natal age were randomized at 6 months corrected post natal age to receive either early intervention program or early intervention program plus Cerebrolysin injection of 0.1 mL/kg body weight every week for 3 months as an adjuvant therapy. The primary outcome was the rate of failure of the gross motor assessment at 12 months of corrected age and secondary outcomes included fine motor, language, and personal social development at 12 months corrected post-natal age as assessed by Denver Developmental Screening Test II.

RESULTS:

Cerebrolysin group had a significant lower number of infants diagnosed with failed gross motor development compared to infants in the routine intervention group [10 (33%) versus 21 (70%), p = 0.009]. Cerebrolysin group had a significant lower number of infants diagnosed with failed fine motor, language and personal social development compared to infants in the routine intervention group.

CONCLUSION:

Cerebrolysin, as an adjuvant therapy to routine early interventional care, may improve gross motor development of high-risk preterm infants at 12 months corrected post-natal age.
Bleeding cervical varices in pregnancy: A case report and review of the literature
Authors: Poliektov Natalie , Kahn Bronwen F.
Published: April 2021

BACKGROUND:

Venous varicosities are a relatively common finding during pregnancy. Rarely, varices can arise in the cervix and cause life-threatening maternal hemorrhage. This article offers an example of a patient who was diagnosed with bleeding cervical varices during pregnancy and summarizes the diagnosis and treatment strategies for the 20 other reported cases in the literature.

METHODS:

A PubMed literature search using the following terms was performed to gather data for the literature review: “bleeding” or “hemorrhage” and “cervical varices” or “cervical varix” or “cervical varicosities” and “pregnancy” or “obstetric” or “maternal.” Individual references cited in each article were also evaluated for inclusion in this review.

RESULTS:

A 50-year-old gravida 7 para 1 presented at 12 4/7 weeks with vaginal bleeding. Endo-vaginal ultrasound showed enhanced color Doppler signal in the endocervical canal. During a speculum exam, she was found to have active bleeding from ruptured cervical varicosities and required blood and fresh frozen plasma transfusion. Hemostasis was achieved with interrupted suture ligation. A McDonald cerclage was subsequently placed. She continued pregnant until delivery via cesarean section at 37 2/7 weeks. To date, there have only been 20 other reported cases of bleeding cervical varices during pregnancy.

CONCLUSIONS:

This case report and review of the literature highlight the importance of including bleeding cervical varices in the differential diagnosis of maternal hemorrhage and offer a treatment strategy if cervical varicosities are discovered during pregnancy.

Authors: Imad N. , El Idrissi Slitine N. , Alaoui S. , Zalle I. , Boumzebra D. , Bennaoui F. , Maoulainine F.M.R.
Published: April 2021

BACKGROUND:

Aortic thrombosis in neonates is a rare phenomenon, and in most cases iatrogenic. An early recognition of the clinical features and an immediate intervention can offer a better prognosis, and thus preventing morbidity such as limb amputation, and even mortality.

METHODS:

We present two cases of full-term newborns with a thrombosis of the abdominal aorta hospitalized in the neonatal intensive care unit of Mohammed VI University Hospital in Marrakech in 2017 and 2019.

RESULTS:

The two patients presented swelling and cyanotic lower limbs. Doppler ultrasound revealed a pathological lower limb blood flow as a result of a thrombosis of the abdominal aorta. Both patients underwent an anticoagulant therapy, the first one benefited from a surgical thrombectomy, he developed a reperfusion syndrome with alveolar hemorrhage, and passed away as a result of a cardiorespiratory arrest. However the second patient got amputated of the right foot, his clinical evolution was favorable with a good healing of the surgical wound without recurrence of any thrombosis.

CONCLUSION:

Through those cases clinicians should be aware of the first clinical signs of this condition in order to offer a rapid and successful management.

Authors: Marchese Victoria , Rock Kelly , York Teresa , Creath Robert , Gray Vicki
Published: April 2021

PURPOSE: This study explored neuromuscular mechanisms and clinical measures that contribute to countermovement jump performance in survivors of childhood acute lymphoblastic leukemia (ALL CCS) compared to age- and sex-matched peers. METHODS: This exploratory cross-sectional observational study examined 12 participants, six ALL CCS and six age- and sex-matched peers (7–16 years). During a countermovement jump, rates of muscle activation of lower leg muscles were measured with electromyography, and joint torques and peak jump height with force plates and a motion capture system. Clinical measures included muscle extensibility, balance, and mobility measured by active ankle dorsiflexion, Bruininks-Oseretsky Motor Proficiency (BOT-2), and Timed Up and Go (TUG) tests. RESULTS: Compared to peers, ALL CCS demonstrated reduced gastrocnemius muscle extensibility and tibialis anterior rate of muscle activation, decreased jump height, and poorer performance on the BOT-2 and TUG. Jump height was significantly correlated with clinical measures of the BOT-2 and TUG. CONCLUSION: These ALL CCS demonstrated neuromuscular impairments that may impact jump performance, an essential childhood physical activity. Further research is needed to explore intervention strategies to improve the neuromuscular mechanisms that contribute to high-level gross motor skills in ALL CCS.

Many systemic functions display circadian rhythms driven by an endogenous mechanism that is regulated by circadian-related genes and these gene expressions control a central clock in the brain and subordinate clocks in peripheral tissues. However, modern life has introduced environmental factors that often interfere with natural circadian rhythms. Importantly, circadian disruption has been identified as an independent risk factor of cancers. Melatonin is a major circadian rhythm regulator. In cancer patients, the rhythm of melatonin is often disrupted and its level is also reduced.  These changes of melatonin impair its antioxidant and circadian regulatory functions on cells and tissues making them more susceptible to mutations and cancer initiation. In this context, the objectives of this study are to evaluate the sleep quality and blood levels of melatonin in patients with either prostate cancer (PC) or hepatocarcinoma (HCC) with the intent of using its levels as a potential biomarker of the cancers. The study involved 20 PC and 18 HCC patients, and 26 healthy volunteers. All blood samples were collected in the early morning, at 07:00 hours. Comparative sleep quality between PC, HCC patients and control subjects was acessed with a questionnaire, and melatonin and vitamin D were measured using conventional assays. The results revealed that patients with the worse sleep quality also had lower values of melatonin and vitamin D compared to control subjects. Notably, expression of melatonin-synthesizing enzymes and specific clock genes (PER, CRY and BMAL1) were significantly reduced and associated with worse prognosis in PC and HCC patients. These findings are consistent with the results of previous studies and suggest that disruption of the circadian rhythms, associated with changes in the light:dark cycle, has consequences for the maintenance of systemic health. We suggest that supplementation of melatonin and vitamin D may represent the important therapeutic strategies for patients with solid tumors for the purpose of improving their sleep quality and recuperative capacity.
Melatonin as a prospective metabolic regulator in pathologically altered cardiac energy homeostasis
Authors: Sarkar Swaimanti , Chattopadhyay Aindrila , Bandyopadhyay Debasish
Published: April 2021

A constant energy supply is indispensable for the relentlessly working heart. The unique metabolic flexibility of the cardiac tissue enables it to maintain its energy requirement under variable physiological conditions. However, some physiopathological statuses including aging, ischemia-reperfusion injury, diabetic cardiomyopathy, pathological cardiac hypertrophy, and heart failure frequently cause cardiac dysfunction and detrimental metabolic alteration. If the ATP supply fails to match the requirement of a working heart, the heart loses its functional capacity, resulting in slower recovery. A decrease in energy generation is often the ramifications of myocardial mitochondrial dysfunction and oxidative stress. Melatonin, a broad-spectrum antioxidant molecule has an appreciable role in the maintenance of metabolic homeostasis― from a single cell to an entire organism. Melatonin has the capacity to reduce ROS generation, preserve mitochondrial stability, and restore a robust mitochondrial function for unabated ATP production in cardiac tissues. Additionally, melatonin can promote carbohydrate and fat metabolism to further improve the ATP production in heart. In cardiac cells, melatonin upregulates GLUT4 expression either by impeding oxidative stress or by enhancing AMPK activation which accelerates fatty acid oxidation by upregulating PPAR-α and CPT-1α. Melatonin plays a pivotal role in the maintenance of calcium homeostasis in cardiomyocytes by obviating oxidative stress-mediated disruption of SERCA and NCX proteins. A possible role of melatonin to convert the Warburg effect to oxidative metabolism in pathological cardiac events has been recently contemplated. The current review will discuss the possible role of melatonin protecting against cardiac metabolic imbalances under pathological states.

Authors: Akinkunmi Olukemi Yetunde , Pitan Olufemi Richard , Ademolu Kehinde Olutoyin , Osipitan Adebola Adedoyin
Published: May 2021

The gut regions of Epilachna chrysomelina are endowed with multiple enzymes that aid digestion of host plant tissues. Digestive enzymes present in the gut regions of E. chrysomelina during various developmental stages were studied in the laboratory to determine the most destructive life stage of the beetle for proper management measures. Cellulase, α-glucosidase, amylase, lipase and proteinase activities were observed in the guts. The mid-gut recorded significantly higher (p<0.05) enzymes than other gut sections except amylase where higher activity was observed in the foregut. Lipase (38.24abs per min), α-glucosidase (25.65 abs per min) and proteinase (28.70abs per min) activities were significantly higher in the immature stages while cellulase (19.46abs per min) and amylase activities (16.62abs per min) were higher in the adult stage. The 4th instar larval and the adult stages recorded higher enzyme activities and thus can be regarded as the most destructive stages of development.

Properties of Some Minerals and Implications on Cancer
Authors: Kargar Aylar , Saka Mendane
Published: April 2021

Cancer is one of the non-communicable diseases which has more than 100 types. Although cancer mechanism is unclear, in general, it is related to oxidation-reduction reactions. Minerals based on their effects on these pathways, have different influences on cancer condition. Based on the source of calcium and the location of cancer, the results could be varied. Zinc is a mineral which participates in healing the wounds and improves the immune system. Thus, serum levels of zinc could be a predictor of cancer. Selenium has a dose-response relation with different types of cancer and shows the antioxidant roles. However, this element could worsen the patient’s status. Iron creates free radicals in the body however iron deficiency anemia decreases the quality of life and affects the treatment in patients. Copper can cause damages via reactive oxygen species (ROS). In conclusion, the recommendations should be discreetly done, considering individuals’ status.

Este sitio cuenta con una gran diversidad de flora y fauna, su componente cultural incluye actividades recreativas encaminadas al turismo comunitario. Esta nueva modalidad de turismo se convierte en una alternativa viable que genera un beneficio social y económico equitativo entre los miembros de las comunidades. Es por ello, que la presente investigación tiene como objetivo crear estrategias de promoción turística de los principales recursos y atractivos turísticos de la Isla Costa Rica, que fomenten un turismo comunitario. Se ha utilizado una metodología no experimental de carácter transversal descriptivo con un enfoque cualitativo y cuantitativo. Los actores involucrados para el estudio fueron la comunidad, los prestadores de servicios, los turistas y la gobernanza. Los resultados muestran que la falta de gestión por parte de las instituciones gubernamentales en infraestructura, promoción y difusión, ha provocado que este recurso natural quede en el abandono. Además, la comunidad predispuesta en implementar la actividad turística insiste que hay ciertos aspectos que necesitan un estudio técnico de mayor rigurosidad para la conservación ambiental. El ecosistema de la zona es el principal foco de atracción de quienes visitan la isla y con él la comunidad puede brindar al visitante una experiencia única que involucre el enriquecimiento cultural y natural de la región.
Networks of the ‘Repugnant Other’: Understanding Right-wing Political Mobilization in Germany
Authors: Deodhar Bhakti
Published: May 2021

Political scientists and sociologists have long been hesitant in applying frameworks from social movements studies to right-wing collective action. Generally developed for left-wing, progressive, egalitarian movements, concepts like rational mobilization, network analysis and micro-mobilizations are considered an awkward fit for analysis of right-wing political and social groups. This paper argues for the importance of such cross-over analysis on two levels. Methodologically, the paper demonstrates crucial importance of ethnographic fieldwork in study of political groups in order to understand the complexity of internal dynamics of right-wing political parties. Insights are drawn from author’s original fieldwork among rank-and-file members of ‘Alternative für Deutschland’ (AfD), a right-wing party in Germany. Substantively, the paper produces a nuanced empirical account of internal dynamics of right-wing mobilization. The paper argues, using insights from the field, that far from being homogenous, irrational and predictive, the actions of right-wing political activists appear to be multi-layered, complex and indeed rational, however onerous to liberal minds.

Published: April 2021

The aim of this study was to determine the effects of insulin
infusion on oxidative stress induced by acute changes in glycemia
in non-stressed hereditary hypertriglyceridemic rats (hHTG) and
Wistar (control) rats. Rats were treated with glucose and either
insulin or normal saline infusion for 3 hours followed by 90 min of
hyperglycemic (12 mmol/l) and 90 min of euglycemic (6 mmol/l)
clamp. Levels of total glutathione (GSH), oxidized glutathione
(GSSG) and total antioxidant capacity (AOC) were determined to
assess oxidative stress. In steady states of each clamp, glucose
infusion rate (GIR) was calculated for evaluation of insulin
sensitivity. GIR (mg.kg-1.min-1) was significantly lower in hHTG in
comparison with Wistar rats; 25.46 (23.41 - 28.45) vs. 36.30
(27.49 - 50.42) on glycemia 6 mmol/l and 57.18 (50.78 - 60.63)
vs. 68.00 (63.61 - 85.92) on glycemia 12 mmol/l. GSH/GSSG
ratios were significantly higher in hHTG rats at basal conditions.
Further results showed that, unlike in Wistar rats, insulin infusion
significantly increases GSH/GSSG ratios in hHTG rats: 10.02 (9.90
- 11.42) vs. 6.01 (5.83 - 6.43) on glycemia 6 mmol/l and 7.42
(7.15 - 7.89) vs. 6.16 (5.74 - 7.05) on glycemia 12 mmol/l.
Insulin infusion thus positively influences GSH/GSSG ratio and
that way reduces intracellular oxidative stress in insulin-resistant
animals.

The reason to explain the cloud computing assimilation, as well as the understanding of the operational performance, still remains unclear. To investigate this issue, this study has examined the assimilation of cloud computing by examining the organization’s implementation of cloud computing and performance in the Malaysian public sector. Grounded by the Diffusion of Innovation Theory (DOI), Technology-Organization-Environment Framework (TOE) and IS Success Model. This study proposes a framework by decomposing Technological characteristic, Organizational characteristics, Environmental characteristics and Human characteristics as factors. A total of 169 agencies from the Malaysian public sector have participated in this study. Data for all the study variables have been collected through self-administered survey questionnaires and analysed using SEM-PLS. The study has shown that the effect of the operational effectiveness of cloud implementation is at a lower level. The study also reveals that factors of relative advantage, compatibility, perceived risks, top management support, and organizational readiness are found to have a significant effect on cloud computing implementation. However, both external support and government regulations are not significant to the cloud computing implementation in the Malaysian public sector. The results indicate that the model provides a good understanding of the factors that influence the implementation of cloud computing as well as operational performance.

Published: April 2021

This paper examines rural social entrepreneurship program in rural Malaysia communities. The program seeks to promote and turn rural entrepreneurs into social entrepreneurs by strengthening their economic activities and enhancing social capital. This paper focuses on a component of the rural entrepreneur program (REP), namely the Social Entrepreneur Club (SEC). The club runs the rural entrepreneur program and upholds the program’s objectives. It promotes the socialization of rural communities by engaging them in entrepreneurial activities. The club operates under the Rural Internet Centre (RIC); a telecentre that provides space for rural communities to enhance their ICT knowledge and skills. However, despite the opportunity provided, some of the rural entrepreneurs do not show adequate interest in the program as they prefer being entrepreneurs, but not social entrepreneurs. Thus, the success of the SECs depends on the entrepreneurs’ participation in the program, the geographical locations and the support from the telecentre managers. This paper employs the economic gardening concept and community informatics approach to empirically gather evidence to test the theory on ICT for development; particularly rural development for rural communities. A quantitative method has been used to measure the implications of ICT in this program. Data from the entrepreneurs is obtained through an online survey which has been conducted across the varying regions in Malaysia. The quantitative data is supported by interviews (qualitative method) with telecentre managers. The primary data has been triangulated to analyze the results. The key findings show that the SEC is seen as economic development strategy by creating jobs, as well as increasing income and business opportunities. It also strengthens social networking needed to build social capital within and outside of the rural communities. Hence SEC is also a community connector and can be used as an indicator on the quality of rural communities’ wellbeing.

Published: April 2021

This research aims to investigate the impact of packaging on customers’ purchase intention in Malaysia. Many studies show that the outward appearance of a product’s package will appeal and consumers’ attention towards the products displayed in the open market. Since the consumers’ choice is the primary consideration that marketers emphasize on, packaging has become an important tool for sales promotion by most business organizations. Although a large number of factors can impact customers’ purchase intention, a product’s packaging is the most influential. Therefore, this research looked into the extent of how packaging has influenced the purchase intention of customers. Findings from the study show that three hypotheses out of four were supported which lend support to the vital role that packaging plays in creating appeal and influencing customers’ purchase intention. The conclusion of this study provides the theoretical implications and practical implications as well as suggestions for future studies in different industries.

Published: April 2021

Due to increasing awareness of Halal food products, customers are becoming more concerned about the food they purchase. Marketers often presume that they will purchase the food products if the Halal indicators are labeled. However, there is no clear standard on what determines the food to be Halal and will be chosen by the customers. Therefore, this study intends to identify the Halal-related factors that contribute to purchase intention. We conducted a survey that involves customers of a Malaysian large retail hypermarket brand. Based on the analysis of 368 usable responses, four factors were found to be essential in influencing customers’ purchase intention, namely: religious belief, Halal certificate, marketing concept, and Halal awareness. Contrary to our expectations, word-of-mouth fails to exert any contingent effect on purchase intention. The findings can be utilised by retailers in ensuring that their food products possess these elements in order to attract Muslim customers to purchase them.
