A decision making framework for foundry sand using life cycle assessment and costing techniques.
A Framework for decision making in the foundry industry on the lines of Life Cycle Assessment has been proposed. It attempts to provide a common normalised ground on which alternative technologies and options may be compared on the basis of economic costs and environmental effects. The framework estimates the total life cycle costs of sand in the foundry. Total life cycle costs is made up of two sub costs--economic cost and environmental cost. Individual cost components that make up these sub costs are calculated and added up. This cost structure is then used to compare processes in a Criterion Function Decision Matrix. Weights of the Criterion Variables are decided using the Analytical Hierarchy Process. The alternative with the minimum Criterion Function is judged the best. A Software using DELPHI was developed on basis of this framework.Dept. of Industrial and Manufacturing Systems Engineering.

Data on mass spectrometry based identification of allergens from sunflower (Helianthus annuus L.) pollen proteome
AbstractAllergy is a type of abnormal immune reactions, which is triggered by environmental antigens or allergens and mediated by IgE antibodies. Now-a-days mass spectrometry is the method of choice for allergen identification based on homology searching. Here, we provide the mass spectrometry dataset associated with our previously published research article on identification of sunflower pollen allergens (Ghosh et al., 2015 [1]). In this study allergenicity of sunflower (Helianthus annuus) pollen grains were primarily investigated by clinical studies followed by detailed immunobiochemical and immunoproteomic analyses. The mass spectrometry data for the identification of allergens were deposited to ProteomeXchange Consortium via PRIDE partner repository with the dataset identifier http://www.ebi.ac.uk/pride/archive/projects/PXD002397
When Silent Actors Talk: Bodies as Learning Infrastructure in the Post-Pandemic World
This paper is based on a qualitative research study that explored the lived experiences of 25 high school students when they first transitioned to online learning during the Covid-19 lockdown. The objectives of the study were to describe the lived experiences of high school students who transitioned to online learning during the lockdown in terms of their learning, and their mental and physical wellbeing; and to map the resources and strategies deployed by the students to navigate difficult circumstances of studying during a global public health crisis. The study employs actor network theory in education, a sociomaterial approach, in identifying the silent taken-for-granted human and non-human actors that constitute learning infrastructures whose presence and effects become visible only during infrastructural breakdowns such as the pandemic. The findings are organized into four themes each of which identify different aspects of the resources, that is, learning infrastructures needed for high school students to learn well. The first theme describes how learners are affected by the shift in the responsibility of providing learning infrastructure from private schools to private homes. While the second theme focuses on how historically developed classroom surveillance mechanisms play out when the body is no longer visible, the third theme explores how bodies can be envisioned as technologies of engagement. The last theme explores how students as integral beings respond physically and emotionally to the learning process. The findings of the study have implications for policymakers, school leadership, and educators to expand their understandings of learning infrastructures needed for learning in post-pandemic online and offline contexts
On the Low Surface Magnetic Field Structure of Quark Stars
Following some of the recent articles on hole super-conductivity and related
phenomena by Hirsch \cite{H1,H2,H3}, a simple model is proposed to explain the
observed low surface magnetic field of the expected quark stars. It is argued
that the diamagnetic moments of the electrons circulating in the electro-sphere
induce a magnetic field, which forces the existing quark star magnetic flux
density to become dilute. We have also analysed the instability of
normal-superconducting interface due to excess accumulation of magnetic flux
lines, assuming an extremely slow growth of superconducting phase through a
first order bubble nucleation type transition.Comment: 24 pages REVTEX, one .eps figure, psfig.sty is include
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
Market Arrival and Price Behaviour Analysis of Potato in Four Major Markets in India
Vegetable plays key role in providing nutrition to human body. Vegetables are major sources of vitamins,
minerals, fiber, iron, calcium etc. Potato is the highest yielding vegetable in the world as well as in India.
It is one of the significant vegetables of Indian consumer’s food basket. Despite of high production, due to
seasonal production and perishable nature market arrival and price are highly volatile in nature. So, the
present study was conducted with an intension to study the trend in arrival and price of potato in four
major markets in India along with their Compound Annual Growth Rate (CAGR) and seasonality and
variability associated with them. The study is based on secondary data collected from www.agmarknet.
gov.in. Data was collected for the period March 2009 to March 2019, and the analysis was done based on
that. Linear trend in arrival and nominal prices were found to be positive across the markets, however
for real prices, it was found negative except Bangalore (` 5.50/q per annum). CAGR for arrival in all the
four markets were found positive, and for real prices it was negative in most of the months. The main
season of arrival of potato in different markets was December to March, and for prices index is highest
during the off season. Variability in arrival is highest in Agra market and in price variability is highest
in Azadpur market
An investigation on performance of onion price and market arrivals in major Indian markets
Onion is a significant and essential commodity used in all the Indian delicacies either in raw form or dehydrated form to add flavour and taste to cuisine. India is the 2nd largest producer of onion next to china and it is also 2nd highest yielded vegetable in India. Though it shares a considerable amount of area and production among all the vegetables along with high marketable surplus, it fails to approve steady price throughout the year. Instability in market arrival contributing to the price fluctuations is mainly caused by substantial dependence on meteorological conditions and perishable nature of the crop. Often this high price fluctuation and variation in price causes suffering to the farmers by affecting their income level. It impacts the consumers adversely and also causes inefficiency in the functioning of the market. Realising the importance of the situation, through this paper it has been investigated. The trends in market arrival were positive in three markets except Azadpur. Trend in nominal price is found positive and for real price it was found negative in all the markets. Seasonal index showed that the arrival in different markets remained on the higher side during the peak harvesting season of the particular region and it collides with the low seasonal price index. Variability index revealed the existence of high variability for both of price and arrivals of onion. However, because of presence of significant seasonality in prices there is scope for increasing the income of farmers by concentrating on marketing during lean periods

Detection of glycoprotein allergens in sunflower pollen and their antigenecity by metaperiodate mediated deglycosylation study in 2D blot: A. PAS staining of sunflower pollen protein in 1D SDS-PAGE to detect the glycoproteins, which turned into purple colors. The PAS stained gel was compared with IgE-immunoblot shown in Fig 1, which identified three glycoprotein regions as possible IgE reactive zones highlighted in boxes. Lane 1: sunflower pollen rotein in SDS-PAGE after PAS staining, Lane 2: Counter staining the PAS stained gel with CBB- G250 that turned only non-glycoproteins into blue. B & C. 2D immunoblot without metaperiodate treatment (B) was compared with another 2D immunoblot after metaperiodate (C) treatment.
<p>The metaperiodate treatment resulted in loss of IgE reactivity of certain spots (marked within box) suggesting the possible involvement of sugar moiety to determine the IgE binding of the allergens.</p
