Liquid isoprene rubber as a safe processing aid in natural rubber compounds

In order to overcome the carcinogenic ‘polycyclic aromatic hydrocarbon’ emission from aromatic oils, which are restricted in European countries since 2010, various efforts have been made to replace the aromatic oil in rubber-based compounds either fully or partially. The authors in the present work have used liquid isoprene rubber (LIR50 or LIR) as a reactive plasticizer in natural rubber (NR) compound at different loadings (2, 4, 6 and 8 phr) and have studied its effect on viscosity, curing characteristics and physico-mechanical properties. These results were compared with the control compound containing conventional aromatic oil as plasticizer. From the experimental data, it was noticed that, the minimum torque for control compound was 0.33 dNm and that for LIR based compounds ranged between 0.16 to 0.56 dNm. The LIR based compounds exhibited slightly higher Mooney viscosity but offers the same scorch safety. The study supports the utility of LIR as a promising alternative, as revealed by the comparable rheological and physico-mechanical properties attained with the usage of appropriate quantity of LIR, unlike the other alternatives of the previous investigations that usually showed a property difference. Keywords: aromatic oil, liquid rubber, reactive plasticizer, safe processing oil.

Creative tourism

Creative tourism has been stimulated as new form of tourism by more skilled forms of tourism activities, by the growth of new consumption patterns, and by changes in the production of tourism products. It can solve that problems experienced by tourists in the conventional tourism. Creativity has many definitions and that based on the function of creativity, it was historically related to creative person, but the recent research in creativity focused on creative product. However, creativity can be located in four areas, and they are: creative person, creative product, creative process, and creative environment. Creativity means “the production of novel and useful ideas in any domain”, which refers to the generation of ideas. Today, creativity becomes as a strategy that promoting individual skill development and innovation, this strategy has been followed by many cities and regions around the world in order to obtain the growth throughout commodification, knowledge development, globalization and increasing competition. Creativity can play a significant role in the mainstream tourism experiences that can be added to the places’ atmosphere, creativity is considered as an attractive policy for stimulating other creative activities and outcomes of social, economic and cultural through spilling knowledge and networking. Indeed, creativity can impact tourism in many ways such as: tourism itself as a creative area, tourism products, skills development and performance development. Thus, the important role of creativity in tourism has been incarcerated in many trends

Surface modification of anhydrous borax with stearic acid by wet coating method

The wet coating of anhydrous borax powders with stearic acid (SA) to reverse their inherent hydrophilic surface properties was investigated. The coating procedure was based on the results from a previous study that revealed that the stearic acid solution (2 wt. % SA) mixed for 60 minute at 750 rpm on the magnetic stirrer was sufficient for the surface modification of anhydrous borax. For the experiments, stearic acid powders were first dissolved in water at 80 °C. The mixture obtained by adding anhydrous borax powders to this solution was vigorously mixed on a magnetic stirrer to initiation and completion the surface modification. Each of these solutions was then filtered using a filter paper to separate the undissolved particles, and the residue on paper was dried at 50 °C for 48 h until constant weighing was obtained. Wettability has been accepted as a key parameter for success in wet coating treatment. This parameter gained via the experimental characterization technique was used for an evaluation of the powder properties. The degree of wettability of anhydrous borax powders was measured and compared both after their surfaces were coated with stearic acid and after they were treated with water for a certain period of time in an aqueous environment. The stearic acid coating made the powder hydrophobic and this property was highly preserved after washing.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.

A memetic algorithm for the inventory routing problem

In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The supply chain network consists of a supplier using a single vehicle with a given capacity to deliver a single product type to multiple customers. We are interested in population-based algorithms to solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic Algorithm (GA) and Variable Neighborhood Search methods. The proposed meta-heuristics are tested on small and large reference benchmarks. The results of the MA are compared to those of the classical GA and to the optimal solutions in the literature. The comparison shows the efficiency of using MA and its ability to generate high quality solutions in a reasonable computation time.

Employment status of persons living with mental illness in india: ground reality

The main aim of rehabilitation is vocational independence and community integration. Rehabilitation is complete with the person being a productive member within the community. But this is quite a challenging task as can be vouched by any of the professionals working in this field. What are the barriers and facilitators towards employment or return to work in case of persons living with mental illness? Literature shows that multiple factors are governing the ability to take up gainful employment. Most of this literature is about the western world where the social fabric is more supportive of individual autonomy. India lags in its rehabilitation efforts for mental illness. There is still stigma and lack of awareness about mental illnesses. This increases the problem of unemployment within persons living with mental illness manifold. There are very few detailed investigations into the vocational status of persons with mental illness and almost negligent literature existing in the Indian context. Hence, the current review article tries to examine the factors prevailing in the Indian scenario that influences the employment status.


Incidence of gestational hypertension among pregnant women (2006-2015) in enugu state, southeast nigeria: a retrospective study

Background: Gestational hypertension (GHTN) is defined as a new rise in blood pressure (BP) ≥140/90 mm Hg, presenting at 20 weeks gestation without significant proteinuria. Worldwide, 4.4%-15% of all pregnancies are complicated by HTN. The aim of this study was to determine the incidence of GHTN among pregnant women in Enugu State, Southeast Nigeria with a view to improving and strengthening antenatal services in the State to help reduce the proportion of maternal mortality and fetal outcomes attributable to GHTN and reduce the overall prevalence of HTN in the country. Methods: Records of BP, biodata and laboratory investigations (urinalysis, full blood count) of women who attended antenatal clinics in six selected state hospitals (2006-2015) were examined. Data were analyzed as proportions, t-test, ANOVA and Pearson product moment correlations using Maxstat (version 3.60) statistical software. Results: The overall incidence of GHTN was 5.9% with annual fluctuations with peaks in 2010 and 2014. There were significant differences in incidence among the age groups (<20>35 years) (p<0 p=0.0016).>35 years) and GHTN (r=0.932, p=0.0069). Between parity and GHTN, there was also positive, strong and significant correlation (r=0.813, p=0.0491). Conclusions: With an incidence of GHTN at 5.9%, there is need to improve and sustain adequate antenatal services in order to help reduce the proportion of the country’s maternal mortality attributable to hypertensive disorders of pregnancy.
