Growth Performance, Carcass Traits and Meat Quality in Broilers, Fed Flaxseed Meal
Mridula, D.,Kaur, Daljeet,Nagra, S.S.,Barnwal, P.,Gurumayum, Sushma,Singh, K.K. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.12
The effect of flaxseed meal on broiler performance, carcass characteristics, alpha-linolenic acid contents, and organoleptic characteristics of chicken meat was studied during a 42 day experiment. Broiler chicks were randomly allotted to 4 experimental groups and fed iso-energetic and iso-nitrogenous diets containing flaxseed meal at 0, 5, 10 and 15%. Flaxseed meal did not affect the weekly body weight of broiler chicks during the first two weeks but thereafter weekly body weight reduced among flaxseed meal groups. At the end of $6^{th}$ week, birds fed on 15% flaxseed meal showed a reduction of 8% in body weight compared to the control group. Control group had significantly higher weight gain with slightly higher feed consumption and better feed conversion ratio (FCR), protein efficiency ratio (PER), and energy efficiency ratio (EER) than the flaxseed meal groups. Among the treatments, birds of 5 and 10% flaxseed meal groups had significantly better FCR, PER and EER compared to those of the 15% flaxseed meal group. The carcass characteristics data indicated a significant reduction in the eviscerated weight and breast yield at 15% flaxseed meal in the diet as compared to other dietary groups. However, the alpha-linolenic acid content in both breast and thigh meat was higher with an increasing level of flaxseed meal in the diets without affecting the sensory acceptability of meat. Based on the present study, up to 10% of flaxseed meal may be used in broiler diet to enhance the alpha-linolenic acid content in the broiler meat.

Selective aerobic-oxidation of glycerol to lactic acid over ruthenium-vanadium bimetallic catalysts
Hanumanth Reddy Pemmana,Prince Kumar Barnwal,Ramagopal VS Uppaluri,Nageswara Rao Peela 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.124 No.-
Ongoing trends to increase biodiesel production translates into enhanced surplus glycerol production,driving the need to develop value-added products, such as lactic acid, from glycerol. The present workis devoted to synthesizing Ru-V bimetallic and monometallic catalysts supported on activated carbonand testing them to produce lactic acid from glycerol through selective aerobic oxidation. The synthesizedcatalysts were thoroughly characterized to obtain morphological and structural properties, elementalcomposition, and surface area. The Ru-V2O5/AC (Ru-V/AC) bimetallic catalysts demonstrated superiorperformance to monometallic Ru and V catalysts, exhibiting a synergistic effect. The Ru-V/AC bimetalliccatalyst containing 1.5 wt% Ru and 0.5 wt% V exhibited the best catalytic performance with a lactic acidyield of 75.5% at 98.7% glycerol conversion under mild operating conditions (1 NaOH/glycerol molar ratio,4400 glycerol/metal molar ratio, 473 K temperature, 5 Bar air pressure and 3 h reaction time). The Ru-V/AC bimetallic catalyst showed good stability during the reaction with only a marginal loss in activitywhen reused for four consecutive cycles, suggesting that this catalyst can be recycled multiple times.

Background: Breast and cervical cancers are the most common causes of cancer mortality among women in India, but actually they are largely preventable diseases. Although early detection is the only way to reduce morbidity and mortality, there are limited data on breast and cervical cancer knowledge, safe practices and attitudes of teachers in India. The purpose of this study is to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection. Materials and Methods: This assessment was part of a pink chain campaign on cancer awareness. During cancer awareness events in 2011 at various women colleges in different parts in India, a pre-test related to cervical cancer and breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive session, at 6 months and 1 year. Results: A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7 %). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self examination (BSE) was significantly more frequent in comparison to CBE, mammography and the Pap test. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer in more than 60% of teachers where as more than 75% were educated by doctors regarding the Pap test. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not doing screening test were found to be ignorance (50%), lethargic attitude (44.8%) and lack of time (34.6%). Conclusions: Level of knowledge of breast cancer risk factors, symptoms and screening methods was high as compared to cervical cancer. There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of BSE was significantly greater in comparison to CBE, mammography and the Pap test. To inculcate safe practices in lifestyle of people, awareness programmes such as pink chain campaign should be conducted more widely and frequently.
