Introduction- Vatarakta is an illness where both Vata and Rakta are afflicted by distinct etiological factors. Vata- rakta is also possible when Gati of Vata is hindered by morbid Kapha Dosha. In modern science Gout shows sim- ilar characteristics like Vatarakta. It is occurred by accumulation of urate crystals in tissues. It starts from small joints to major joints. Pippali Vardhamanak is advised by Aacharya Sushruta for treatment of Vatarakta and other Vata-Kaphaj Vyadhi. In this VardhamanMatra of Pippali is given as said by Aacharya. Pippali has anti- inflammatory, rejuvenating properties and also act as Vata-Kapha Shamak. Aim- To evaluate therapeutic efficacy of Pippali Vardhamanak in Vatarakta with special reference to Gout. Objectives- To study therapeutic efficacy of Pippali Vardhamanak to reduce the symptoms of Vatarakta with special reference to Gout. Materials and Methods- The present study was conducted in 30 patients having clas- sical symptoms of Vatarakta. The patients were given Pippali Vardhamanak for 15 days. Pippali has Katu Ras, Laghu-Teekshna Snigdha Guna, Madhur Vipaka and Anshna Veerya, due to these proper- ties it acts as Kaphashamak, Vatashamak and Raktashama, Strotoshodhana. Piperine inhibits monosodium urate crystals. Conclusion- Pippali Vardhamanak gives significant relief in Vatarakta with special reference to Gout. Keywords: Vatarakta, Gout, Pippali, Pippali Vardhamanak

Introduction: Prakriti stands for nature of the body in terms of Dosha and is decided at the time of conception according to the predominance of Dosha. According to Ayurvedic Acharyas, Prakriti of an individual cannot change during his whole life, same as blood group of an individual does not change during his life. In the present study, a relationship between Deha Prakriti and Blood Group was established. Aim and Objective: The aim of the study is to find an association between Deha Prakriti and Blood group in healthy individual. Material and Methods: For this study to be carried out, a total of 150 healthy individual (50 of each dominant prakriti) were selected. Assessment of Prakriti was done using K. Patwardhan and R. Sharma, “Prakriti: a self-assessment questionnaire” and Blood group sample was taken and investigations were carried out in pathology lab, Ch. Brahm Prakash Ayurved Charak Sansthan, Khera Dabar, Najafgarh, New Delhi and A one-way repeated measures ANOVA also known as a within-subjects ANOVA was applied to test the association between Deha prakriti and Blood group in healthy individual. Results The prevalence of different blood group as found in our study is in the order of B+, O+, A+, AB+, A-, AB-, B- and O- respectively. On analyzing the blood group with respect to Prakriti types, association was noticed between blood group type B with all single Doshaj Prakriti (Vataj, Pittaj and Kaphaj). This study shows that blood groups cannot be thus used as features to classify dominant Prakriti as no statistically significant association was found between them (p > 0.05). Keywords: Blood group, Prakriti, Vata, Pitta, Kapha.

Many fundamental principles have been explained in Ayurveda, having specific terminology which cannot be compare with any other terminology in modern medical science and Srotas is one of them, having more function- al importance rather than structural, which are enamors and Akasha Mahabhuta is mainly involves in its constitu- tion. Srotas play a significant role in the circulation and transportation of various materials including micronutri- ents throughout the body, having Khavvaigunya property which provides the space for accumulation of vitiated Dosha & Dushya. In the pathogenesis of any diseases ‘Doshadusya Sammurchhana’ is an important event, which happened in the Srotas and the whole process is known as Srotodusti. It is of 04 type viz. Atipravriti (Increase activity/flow), Sang (Obstruction), Siraagranthi (Reduction of the lumen of the system) & Vimarggaman (Oppo- site direction flow). The management of disease depends upon Srotodusti as well as type of Srotas involved in the pathogenesis of specific disease. The characters of Srotas involve and type of Sroto Dusti affect the treatment plan and as well as the prognosis of disease.

Vasti has been told as Ardhachikitsa and is applicable in all the Vatavyadhi. As a general rule, when Rogas are caused by Vata Dosha alone, without the association of Ama, then Sneha Vasti should be given. Matra Vasti is one among the Bheda of Sneha Vasti, it can be given to any person irrespective of age and Ritu, without any strict regimen of Ahara and Vihara. SandhiVata is a Vatika disorders and Dhatukshaya is its prime factor. Vata Dosha is the regulator of other two Dosha, Dhatu and Mala and also all the body activities. Therefore, once Vata is con- trolled by Vasti, all these factors are automatically regulated, and total body equilibrium is achieved. Sandhigata Vata is characterized by symptoms like joint stiffness, joint pain, swelling and difficulty in joint movements, etc. Snehana is mentioned as one of the main treatments of Sandhigata Vata. According to therapeutic administration, Sneha Paka is mainly 3. Acharya Charaka and Vagbhata explained Sneha in Madhyama Paka for Vasti Karma, whereas Acharya Susruta opines Sneha in Khara Paka for VastiKarma. Here in this study, MatraVasti with KsheeraBala Taila prepared in two different Paka is selected. A group of 40 patients with signs and symptoms of Janu Sandhigata Vata, fulfilling the inclusion criteria and were randomly divided into two groups with number of twenty. MatraVasti with Ksheerabala Taila prepared in Khara Paka was given to Group A and Madhyama Paka was given to Group B for consecutive 9 days. Patients were evaluated thoroughly prior to the treatment, on 9th day of treatment and on 18th day of follow up period on the basis of subjective and objective parameters. Statistical analysis revealed that both groups were statistically significant in all subjective and objective criteria in after treatment results and after following up results.

In this study, fines-enriched pulp (FE-pulp)—the fine fraction of highly-refined kraft pulp—was benchmarked against highly-refined kraft pulp (HRK-pulp) as a strength agent in eucalyptus chemithermomechanical pulp (CTMP). Both the FE-pulp and the HRK-pulp were produced from unbleached softwood kraft pulp, and equal amounts of those strength agents were added to the original CTMP, as well as to washed CTMP, where most of the fines had been removed. The effects of the added strength agents were evaluated with laboratory handsheets. The FE-pulp proved to be twice as effective as HRK-pulp. Both HRK-pulp and FE-pulp increased the strength of the CTMP handsheets. The bulk of the handsheets decreased, however, as well as the drainability. The addition of 5% FE-pulp resulted in the same strength increase as an addition of 10% HRK-pulp, as well as the same decrease in bulk and CSF. For the handsheets of washed CTMP, the strengths were not measurable; the CTMP lost the sheet strength when the CTMP-fines content was reduced through washing. The reduced strength properties were compensated for by the addition of chemical pulp fines that proved to be an efficient strength agent. The addition of 5% FE-pulp restored the strength values, and at a higher bulk and higher drainability.

Predictions from empirical models are affected by variability in the input parameters for the data set used to build the models. For corrugated boxes, the difference between actual and modeled compression strength creates a real cost associated with box production, often resulting in boxes that may need to be over-designed to compensate for a lack of model precision. No work to date has attempted to assess the limitation in these compression estimates due to input parameter testing variability. In this paper we approach that problem, initially for the McKee equation and then conceptually for other box models. For our industry to do a better job at meeting the needs of our corrugated packaging customers, we need to reduce the variation in the tests we all rely on, particularly for evaluating material strength (edge crush test [ECT]) and package compression performance (box compression test [BCT]).

Refiner plates made using sand casting have a draft angle, which results in a trapezoidal bar shape. These trapezoidal bar plates have a limited throughput compared to the vertical bar plates, and eventually the edges of the bars become dull, resulting in longer time to reach the target freeness and shorter service life. The new light-weight refiner plate with a bar insertion method into a plate base was developed by selecting an aluminium-based alloy as the plate base material and a stainless steel alloy with high wear resistance as the bar material. The light-weight plate with sharp bar edges was very effective in reducing refining energy by reaching the target freeness faster than the sand-cast bar plate. Finally, the lightweight sharp bar plate, which weighed only about half the weight of the cast bar plate, was expected to significantly contribute to easy replacement, improved paper quality, and larger throughput without excessive loss of fiber length.

This paper reports the use of multicriteria analysis in the Analyze phase of the DMAIC (Define-Measure-Analyze-Improve-Control) cycle for continuous improvement. The research was carried out in a tissue paper factory located in southern Brazil. A sample of 64 parts of 16 different reels of recycled paper was used. A problem regarding paper quality variability was detected, presenting a scrap index ranging between 9% and 23%, compromising machine productivity and product sales. This motivated the implementation of a structured project supported by the application of the DMAIC cycle. The project team (machine operators, maintenance staff, supervisor, and data analyst) defined the evaluation criteria and determined the control intervals and their equivalence with linguistic variables to support the necessary evaluations for the application of fuzzy TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution). The criteria were C1-Longitudinal Strength (Kgf), C2-Longitudinal Elongation (mm), C3-Cross-strength (kgf), C4-Cross-elongation (mm), C5-Weight (g/m²), and C6-Humidity (%). The results showed that samples with the same ranking had the lowest scrap indexes in the subsequent process. Also, the criterion C5 had a more significant impact on the quality of the product than the other criteria, which was determined from the DMAIC sequence. Improvements related to C5 should be prioritized. The fuzzy TOPSIS method presented is a flexible tool, adapting itself to the solution of the problem and contributing to the decision-making process.

The study aimed to analyse the general impact of the COVID-19 pandemic on global tourism. Obviously, the world tourism industry has been received unprecedented damages never ever seen before. The thematic analysis approach, comparative research method and descriptive statistical analysis are used to investigate the effects of this pandemic. In general, the empirical analysis results show having a high sensitivity to diseases, global tourism is considered as one of the hardest economic sectors hit by the COVID-19 pandemic outbreak. First, these huge losses in revenue are still ongoing because the pandemic is fastly spreading worldwide. The hurts of global tourism are serious and can put the whole travel and tourism industry in long-term disruptions. Second, although global tourism has proven strong resilience in response to other previous crises, the results suggest that the negative impacts of this pandemic will longer-lasting expand on would tourism industry compared to others. Third, the analysis result highlights that the countries need robust and urgent solutions for global tourism to reduce the huge losses received from this pandemic. However, this pandemic can have potential long-term changes in customer behaviors and the supply chain in global tourism to help efficiently combat risks from epidemics in the future. Finally, the study results suggest some implications to policymakers and business people in the reconstruction of the tourism industry in countries in the coming time.

Finally, the study results suggest some implications to policymakers and business people in the reconstruction of the tourism industry in countries in the coming time.","PeriodicalId":8309,"journal":{"name":"April 2021","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74379973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental changes push hotels to seek additional and innovative channels to market their products/services while maintaining a high occupancy rate and revenues with lower marketing costs. Building on network theory, this research investigates the extent to which multi-level marketing (MLM) can be adopted as an appropriate and innovative marketing channel for resort hotels. A Delphi study was undertaken with hotel and MLM experts to explore their perceptions about the opportunities and challenges of MLM for resort hotels. The results showed that MLM could appropriately be developed as an innovative marketing channel for resort hotels if challenges are fully addressed and controlled by hoteliers. Two models are proposed for proper implementation of MLM for resort hotels. The first model uses current customer/s as a marketer/s. This includes sharing resort experience using social media posts. The second model uses MLM companies as a channel for marketing hotel products/services to new customers. Several theoretical and practical implications of the study were discussed.
