A Study on Customer Perception towards Hike in Prices of Online Food Delivery Channels

Online Food Delivery channels have emerged in recent years which have made all the customers almost their slaves across India as most of us heavily rely upon them. At a lesser cost, these help us to order our food items with a wide variety of choice. When it comes to cost, Delivery charges play a major important factor in determining the price of different items through different online food channels.Customers as well as business houses now a days have a contemporary perception of delivery charges associated with such products and services available in the market This research paper explains the customer perception towards their ordering capacity when delivery charges are taken into consideration by them and more often are possibly changed by these food delivery partners. To study the customer perception, a sample size of 106 respondents was chosen and the data collected from such respondents was analyzed using Cross Tabulation and Chi Square Tests. It was elucidated from the analysis that for most of the customers delivery charges influences their capacity to order and most of the times customers have changed their mind to order online food when delivery charges are considerably high

Non-homogeneity effect in the spherical shell by using seth's theory

This paper presents nonlinear deformation behaviour of non-homogeneous spherical shell examined under pressure by using Seth's transition theory. It has been seen that for increased material compressibility in thickness direction, the circumferential stress in the spherical shell reaches maximum at the external surface, but is reverse in the case of a deceasing compressibility in the thickness direction. The spherical shell of non-homogeneous material (non-homogeneity increases radially) is on the safer side of design. Hence, the more use of non-homogeneous material (non-homogeneity increases radially) may be beneficial for manufacturing spherical shells as they provide longer service life than shells of homogeneous material under identical conditions

High spin polarization and the origin of unique ferromagnetic ground state in CuFeSb

CuFeSb is isostructural to the ferro-pnictide and chalcogenide superconductors and it is one of the few materials in the family that are known to stabilize in a ferromagnetic ground state. Majority of the members of this family are either superconductors or antiferromagnets. Therefore, CuFeSb may be used as an ideal source of spin polarized current in spin-transport devices involving pnictide and the chalcogenide superconductors. However, for that the Fermi surface of CuFeSb needs to be sufficiently spin polarized. In this paper we report direct measurement of transport spin polarization in CuFeSb by spin-resolved Andreev reflection spectroscopy. From a number of measurements using multiple superconducting tips we found that the intrinsic transport spin polarization in CuFeSb is high ($\sim$ 47\%). In order to understand the unique ground state of CuFeSb and the origin of large spin polarization at the Fermi level, we have evaluated the spin-polarized band structure of CuFeSb through first principles calculations. Apart from supporting the observed 47\% transport spin polarization, such calculations also indicate that the Sb-Fe-Sb angles and the height of Sb from the Fe plane is strikingly different for CuFeSb than the equivalent parameters in other members of the same family thereby explaining the origin of the unique ground state of CuFeSb.Comment: 6 pages, 4 figure

Analysis and advanced characterization of municipal solid waste vermicompost maturity for a green environment

Rapid demographic expansion along with increasing urbanization has aggravated the problem of solid waste management. Therefore, scientists are seeking waste management methods that are eco-friendly, cost effective and produce immediate results. In the developing world, municipal solid waste (MSW) contains mostly organic substances, therefore vermicomposting could be a better and cost-effective option for waste management. In this study, vermicomposting of organic portion of MSW with cow dung (additive) was performed using Eisenia fetida. The results showed significant (p < 0.001) decline in pH (13.17%), TOC (21.70%), C: N (62.53%) and C: P (57.66%) ratios, whilst total N (108.9%), P (84.89%) and K (21.85%) content increased (p < 0.001) in matured vermicompost. Different enzymatic activities declined during termination phase of vermicomposting experiment with maximum decrease of 41.72 (p = 0.002) and 39.56% (p = 0.001) in protease and β-glucosidase, respectively. FT-IR, TGA, DSC and SEM studies suggested that final vermicompost was more stabilized as compared to initial waste mixture, characterized by reduced levels of aliphatic materials, carbohydrates and increase in aromatic groups possibly due to biosynthesis of humic substances. Both, the conventional (physicochemical and enzyme activity) and advanced techniques depict maturity and stability of the ready vermicompost. However, FT-IR, TGA, DSC and SEM were proved to be more promising, fast and reliable techniques over conventional analyses

Development of a novel HPTLC fingerprint method for simultaneous estimation of berberine and rutin in medicinal plants and their pharmaceutical preparations followed by its application in antioxidant assay

The present study was designed to develop and validate a high-performance thin-layer chromatography (HPTLC) system for the simultaneous quantitative determination of berberine and rutin in Tinospora cordifolia extract and their pharmaceutical preparations. Chromatographic development was done using a blend of n-hexane, ethyl acetate, glacial acetic acid and methanol (10:1.1:1.1:2.5, v/v) as the mobile phase. Detection was completed densitometrically at 254 nm. The RF estimation of berberine and rutin was observed to be 0.67 ± 0.02 and 0.47 ± 0.02, respectively. The developed HPTLC method was validated according to ICH guidelines; the method was specific, linear and accurate and can be used to determine berberine and rutin in marketed herbal preparations. The Tinospora cordifolia plant extract was further evaluated for antioxidant activity using HPTLC, and berberine was found to be more active than rutin during DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity. The method was found simple, rapid, accurate, specific and robust for the analysis of berberine and rutin in crude drug using the same method

Hypoxia-inducible factor (HIF): fuel for cancer progression

Hypoxia is an integral part of the tumor microenvironment, caused primarily due to rapidly multiplying tumor cells and a lack of proper blood supply. Among the major hypoxic pathways, HIF-1 transcription factor activation is one of the widely investigated pathways in the hypoxic tumor microenvironment (TME). HIF-1 is known to activate several adaptive reactions in response to oxygen deficiency in tumor cells. HIF-1 has two subunits, HIF-1β (constitutive) and HIF-1α (inducible). The HIF-1α expression is largely regulated via various cytokines (through PI3K-ACT-mTOR signals), which involves the cascading of several growth factors and oncogenic cascades. These events lead to the loss of cellular tumor suppressant activity through changes in the level of oxygen via oxygen-dependent and oxygenindependent pathways. The significant and crucial role of HIF in cancer progression and its underlying mechanisms have gained much attention lately among the translational researchers in the fields of cancer and biological sciences, which have enabled them to correlate these mechanisms with various other disease modalities. In the present review, we have summarized the key findings related to the role of HIF in the progression of tumors

Developing a Framework for Prediction of Human Performance Capability Using Ensemble Techniques

The recruitment of new personnel is one of the most essential business processes which affect the quality of human capital within any company. It is highly essential for the companies to ensure the recruitment of right talent to maintain a competitive edge over the others in the market. However IT companies often face a problem while recruiting new people for their ongoing projects due to lack of a proper framework that defines a criteria for the selection process. In this paper we aim to develop a framework that would allow any project manager to take the right decision for selecting new talent by correlating performance parameters with the other domain-specific attributes of the candidates. Also, another important motivation behind this project is to check the validity of the selection procedure often followed by various big companies in both public and private sectors which focus only on academic scores, GPA/grades of students from colleges and other academic backgrounds. We test if such a decision will produce optimal results in the industry or is there a need for change that offers a more holistic approach to recruitment of new talent in the software companies. The scope of this work extends beyond the IT domain and a similar procedure can be adopted to develop a recruitment framework in other fields as well. Data-mining techniques provide useful information from the historical projects depending on which the hiring-manager can make decisions for recruiting high-quality workforce. This study aims to bridge this hiatus by developing a data-mining framework based on an ensemble-learning technique to refocus on the criteria for personnel selection. The results from this research clearly demonstrated that there is a need to refocus on the selection-criteria for quality objectives

Fibular fixation as an adjuvant to tibial intramedullary nailing in the treatment of combined distal third tibia and fibula fractures : a prospective observational study

Distal 1/3rd extraarticular tibia fractures are common in trauma centers. It is often the result of high energy trauma,usually associated with distal fibular fractures. Tibia interlocking nail is an established way of treating these fractures. Fixation of fibular fractures in distal tibial metaphyseal fractures is controversial, although fixation of the fibular fracture by a plate partially stabilizes fractures of the distal tibial shaft and considered in distal tibial fractures treated with intramedullary fixation to prevent valgus deformity even there is increased potential for delaying the tibial fracture healing. Objectives: The purpose of this study was to compare the functional and radiological outcome of fractures of distal third tibia and fibula treated by interlocking nail of tibia with fibular plating and without fibular plating. Material and Methods: A total of 48 patients who had fractures of lower third tibia and fibula are included in this study. 48 patients were divided into two groups I and II (24 patients in each group) based on fibular fixation. Results: Functional results were evaluated based on radiological and biological union and absence or presence of complications. In Group A 3 out of 22 patients (13%) showed non union and in Group B 2 out of 21 patients (9%). In Group A 2 out of 22 patients (9%) showed malunion at end of 6 months and in Group B 3 out of 21 patients (8%). In Group A 15 out of 22 patients (68.8%) showed union at end of 6 months without complications and in Group B 14 out of 21 patients (66.66%).Conclusion: Based on the results of the study, it was concluded that union occurred in both groups where fibula was fixed and not fixed with same rates of complications in both groups except infection which was higher in fibula plating cases. In cases where fibula fixation wasn’t planned and distal tibia reduction was achieved using percutaneous clamp.If intraoperatively,reduction wasn’t possible it was seen that if fibula was fixed first then better reduction was achieved. A long term study is required for further exploration on indications of fibular plating in distal fractures of tibia
