Predicting sales in a shoe industry is a typical job due to unpredictable demand of products. Many models are suggested for forecasting the product in the literature over the past few decades. Most shoe manufacturing organizations are in a continuous effort for increasing their profits and reducing their costs. Exact sales forecasting is certainly an inexpensive way to meet the organization goals. This paper studies and compares different forecasting techniques as moving average, single exponential smoothing, double exponential smoothing and winter’s method. For this, domestic sales data from a shoe industry is collected and then data were analyzed by statistics technique using Minitab 17 software. The result shows that the demand of shoes fluctuate over the period of time. The factor that influences the choice of forecasting model is the least value of Mean square deviation (MSD).

Due to rising attention towards environmental and ecological issues caused by mineral oil-based lubricants in machining operations, the developing of an environmental favourable lubricant has become inevitable. As environmental favourable cutting fluids, vegetable oils have acquired great attention in machining operations due to their good biodegradability, nontoxicity and less environmental pollutant properties. Nowadays, the minimum quantity lubrication (MQL) technique is explored as alternative technique to conventional flood cooling technique. However, very limited work is done to investigate the effect of MQL technique using vegetable oils as the base oil for machining of hard materials. Moreover, systematic comparison of different vegetable oils as the base oil will be of great significance to the manufacturing industry. Therefore, in this study, the performance of six vegetable oils viz. castor, coconut, soybean, canola, palm and sunflower oil, and distilled water has been investigated during drilling of stainless steel (AISI 321) using minimum quantity lubrication technology. The main objective of this study is to compare the performance of various cooling strategies viz. dry, flood and seven MQL conditions with respect to drilling characteristics (thrust force, torque, surface roughness, coefficient of friction (COF), chip morphology and wear mechanism) in the drilling of stainless steel (AISI 321) by using HSS drill tools. Experimental findings showed that MQL drilling conditions have given excellent drilling performance by improving drilling characteristics than dry and flood drilling. Among the MQL fluids, sunflower oil provided better lubrication and improved the drilling characteristics followed by palm, canola, soybean, coconut, castor oil and distilled water. Sunflower oil had a thrust force, torque, surface roughness and coefficient of friction of 1425 N, 22.8 Nm, 4.356 μm and 4.000 μ, which reduced by 21.27%, 25.49%, 30.72% and 5.35%, respectively than that under flood drilling at 30th hole. The better lubrication performance of sunflower oil may be attributed to the rich presence of saturated-fatty acids. In addition, vegetable oils based MQL technique is more worthy to improve the cooling capabilities and promote sustainability in the manufacturing sector by saving resources and extending environmental benefits.

Virechana karma (therapeutic purgation) in the restoration of gut microbiota concerning Amavata (RA): A scientific exposition

Godbole, Amrit,Sweta, Sweta,Abhinav, Abhinav,Singh, O.P. Cellmed Orthocellular Medicine and Pharmaceutical 2021 셀메드 (CellMed) Vol.11 No.1

Background: Amavata is a disease that occurs as a result of the error of metabolism. Poor dietary habits and faulty Dincharya (daily regimen) and ritucharya (seasonal regimen) leading to deranged metabolism and Agni (metabolic fire) which results in the formation of Ama(undigested product of metabolism). When Amaconceals with Vata(subtle energy associated with movement) and circulates in the body under the influence of Vyana Vayu (omnipresent air)it clogs the srotasas (microchannels) and initiates the inflammatory cascade. Amavata is commonly correlated with rheumatoid arthritis (RA) while other forms of auto-immune disorders can also be included in Amavata.Dysbiosis of the gut microbiota (GM) has been connected to the onset of diverse autoimmune diseases. In this study, it was hypothesized that Panchakarma (bio-purificatory methods) based intervention such as Virechana Karma (therapeutic purgation) may influence microbiota. Materials and Methods: Various Ayurvedic literature were reviewed for the etiopathogenesis of Amavata. Different databases were searched with research papers related to Gut Dysbiosis and autoimmunity and management of RA. A connecting link between Intestinal Dysbiosis with the autoimmune mechanisms was established and it was also found that the bowel cleansing introduced a change to the GM. Conclusion: It was concluded that Virechana karma is effective in gut flora Dysbiosis. This study aims to correlate the ancient Ayurvedic principles related to Agni Bala(metabolic energy) and biopurificatory treatment modalities like Virechana karma (therapeutic purgation)with the modern concept of gut microbiota and its role in the pathogenesis of various autoimmune disorders such as rheumatoid arthritis. The article creates an understanding about principles of Ayurveda and its rationality in today's scientific world and thereby opens newer vistas of research in therapeutics from Ayurveda, which may be helpful in the management of various immune-mediated Diseases through Ayurveda.

Fabricating bimetallic structures using various additive manufacturing processes is an ingenious way to integrate differentmaterial properties in a single component. This study offers a novel method for fabricating Ti6Al4V and IN718 bimetallicstructures using a wire-arc-based directed energy deposition process with a CuSi interlayer, both with and without the additionof pure copper powder at the CuSi–TI6AlV interface. The Cu–Ti and Ni–Cu interfaces of the bimetallic structure havebeen examined in terms of their metallurgical and mechanical characteristics. The study revealed the presence of Cu4Ti3,Cu3Ti2,Cu4Ti,CuTi2and Ti5Si3phases at the Cu–Ti interface, whereas CuNi and NiCr2phases at the Ni–Cu interface. TheCu–Ti interface with copper powder shows two distinctive layers of intermetallic phases with less intermetallic thicknesscompared to the interface without copper powder. The maximum bonding strength of 152.31 ± 40.74 MPa and hardnessof ~ 485 HV were achieved in the interface without a copper powder sample. However, for interface with copper powdersample, the presence of Ti5Si3hindered the further transformation of less stable Cu–Ti phases resulting in decreased strength.

The search for materials that serve as good shields for radiation has become very important in light of the increasing exposure to ionizing radiation in various vital sectors. The aim is to search for novel materials with better radiation shielding properties that are stable, nontoxic, and abundant and environment friendly. The solidstate reaction approach has been used to synthesize a few ceramics, including BaZrXTi1-XO3, Ba1-XLaXTiO3 and Ba1-XLaXZrXTi1-XO3 (with x = 0.10) i.eBaZr0.10Ti0.90O3 (BZT), Ba0.90La0.10TiO3 (BLT), and Ba0.90La0.10Zr0.10Ti0.90O3 (BLZT). The density of the prepared samples varies from 6.3471 to 11.6003 g/cm3. The X-ray diffraction technique, shows strong peaks to confirm the crystalline structure of prepared ceramic samples. Using the G-P fitting approach, the advanced radiation shielding parameters (build-up factor) have been evaluated in the photon energy region of 1.5 keV–15 MeV. It is observed from the results that exposure buildup factor (EBF) and energy absorption buildup factor (EABF) are maximum for BLZT and has the minimum value for BZT in the entire photon energy regime. The results of this work should be useful in radiation shielding applications such as in industry, medicine, and nuclear engineering.
