Pregnancy is a normal physical state of womens life when they carried a 9 month developmental stages of the foetus. On these durations some pregnancy induced changes leads normal signs naturally but there is an increased risk of musculoskeletal pain or discomforts associated with increase of uterine size and mental stress of pregnant women, needed non-medicines approached like antenatal physiotherapy care. These possible pain or discomforts can make difficult to carry the pregnancy may leadsome complications. Various research studies are point out these problems of pregnant women and find out the triggers.Some studies show the spectrums of these musculoskeletal problems during pregnancy period. Various case studies are assuredtheparticular physiotherapy techniques as antenatal exercises have good impact on relief of respective musculoskeletal pain.Various researches are also covered some another aspects of musculoskeletal problems during pregnancies. In thepresent study an attempt has been made to comprehensive analysis of these review studies to identify the most common musculoskeletal problems in different stages of pregnancy and efficacy of physiotherapy techniques and antenatal exercises to overcome the problem. It was found in the spectrum analysis that most of the women (68.33 %) faced this problem during their pregnancy. On the analysis of most commonmusculoskeletal problem, the mean percent of reviews reveals showed that the most of the women found to be in muscle cramps and pain in neck and shoulder during I trimester whereas maximum women had low back pain (42.87 %) and pelvic girdle pain (11.65 %)on II and III trimester respectively. The satisfactory impacts of antenatal exercises were observed in different musculoskeletal pain by different techniques of Physiotherapy.These results can utilize to make suggestions and recommendations foradoption of suitable physiotherapy techniques in pregnancy to avoid the problem. &nbsp

Biochar (BC) production by microwave (MW) co-pyrolysis of food waste (FW) with polyethylene (PE) (mixed in a ratio of 8:1) was performed in the present study using different MW susceptors, i.e. granular activated carbon (G), silica gel (S), cement (C) and flyash (F). BC yield varied from 37 wt% to 45 wt%. The highest yield of 45 wt% was obtained with flyash as MW susceptor. All BC exhibited increased carbon content (57.1-69.0 wt%), fixed carbon (76.0-85.3 wt%), and porous structure with improved thermal stability than the feedstock. The inferential plot exhibited an inverse relationship between yield and carbon of BC with loss tangent (tan δ) and specific surface area (SSA) of the MW susceptor. Alkali (potassium phosphate) modified F-BC (K-F-BC) showed further improvement in porous structures with a good cavity and presence of carbonyl group (CO) and hydroxide group (O-H) on its surface, which showed good adsorptive removal of metformin (MET). Alkali modification of F-BC improved the adsorption capacity by ∼8 times; thus, resulting in ∼62% MET removal within 5 min. Kinetic models suggested the MET adsorption on BC predominantly controlled by intra-particle diffusion (R

This scientific data article is related to the research work entitled "Optimization of bio-oil production from microwave co-pyrolysis of food waste and low-density polyethylene with response surface methodology" published in "Journal of Environmental Management" (10.1016/j.jenvman.2021.113345). In this work, collection of Food Waste (FW) and Low-density polyethylene (LDPE) for 7 consecutive days and its characterization was done. Based on the characterization, the composition of simulated FW was fixed for different experimental runs. Valorization of feedstock (FW and LDPE) with increasing temperature with/without the presence of microwave susceptor was analyzed. Statistical significance of LDPE and microwave susceptor addition on bio-oil yield and Total Acid Number (TAN) was verified with single-factor ANOVA. The outcomes of the present dataset will be helpful for the researchers and engineers working in the field of bio-oil generation from microwave co-pyrolysis of mixed waste.

The applicability of waste to energy conversion technique is facing many issues because of current waste management practices. Focusing on the segregation issue of low-density polyethylene (LDPE) from food waste (FW), microwave (MW) co-pyrolysis of FW and LDPE was investigated in this study. Multifactor optimization of the operating parameters, viz., residence time, LDPE in feed and temperature, was done with response surface methodology to achieve maximum bio-oil yield with a low total acid number (TAN). Bio-oil yield and TAN varied from 17 to 42 wt% and 16-45 mg KOH/g respectively, in various experimental runs. The optimum conditions for maximum bio-oil yield with minimum TAN were residence time -7 s, LDPE in the feed-13% and temperature - 550 °C. A quadratic model was developed to predict bio-oil yield and TAN as a function of operating parameters with an error
