Positioning errors in digital panoramic radiographs- A retrospective analysis

Objectives of this paper are to analyze the most prevalent positioning errors in panoramic radiographs. 560 OPG taken from January 2016 - January 2017 in the department of maxillofacial radiology were assessed by two maxillofacial radiologists for positional errors. All radiographs were viewed on a computer monitor using the OHP sheet to demarcate the 6 zones. Results 74 radiographs (11.97%) were error-free and 486 radiographs (88.13%) were with errors. The radiographs with single positional error were 423 (84.3%). The radiographs with 2 positional errors were 57(9.89%). The radiographs with 3 positional errors were 6 (1.04%). The outcome of the analysis reveals that the percentage of positioning errors in panoramic radiographs is fairly high reducing its diagnostic value. Technicians are made aware of the errors and are instructed to recheck the patient position before taking radiographs. A similar audit will be repeated on a regular basis to check the change in the prevalence of positional errors.

Analytical method development for combination pesticides of picloram and fluroxypyr by reverse phase High Performance Liquid Chromatography (HPLC)

The herbicide is the part of the pesticide, these herbicide are normally used to control the weeds in the cultivation period. The quality of the herbicide has to be effective and the degradation should be fast. After the usage, the soil fertility has to be maintained without any environmental chain changes. There are many herbicides are available to control weeds or unwanted plants in the cultivation processes. Many of the herbicides are used to control the grass or very small plants, which has a very week in the structure. The Picloram herbicide used to control especially the plant which has strong stem and branches. The usage is unique and this herbicide has to be used carefully to maintain the required cultivated plants during the plantation or cultivation period. There are few herbicides are available to control wood plants. The specialty of the picloram herbicide will not have any action on the grass. Fluroxypyr is another molecule being used as a herbicide in the cultivation industry. The chemical nature of this molecule is similar to that of the picloram molecule. The Fluroxypyr is consisting of the pyridine molecule basically. Fluroxypyr has fluorine, chlorine, amine and an ether arrangement in its structure. This Fluroxypyr is used to control woody plant which has broadleaf. This molecule also has the electronegative structural annulments in it has more penetration power through roots of the plants. Mostly this Fluroxypyr is being used to control weeds in the place where the cultivations are normally carried out. These Picloram + Fluroxypyr molecules were separated through a mobile phase consisting of the mixture of acetonitrile and water (fortified with 0.5% of formic acid) in the ratio of 40:60 v/v. The separation was achieved through the Qualisil BDS C8 (250 x 4, 5μ) column with the flow rate as 1.5 ml/min with the detection at 254 nm. These method parameters were loaded in the Shimadzu HPLC (model: LC-2030). The LC solution Shimadzu software was used for all the calculations in this analytical method validation analysis. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the identification and quantifications of these molecules interims of validation parameters viz., separation, system suitability, System Precision and linearity in a simple HPLC analysis.

Electro-coagulation process used to treat hospital wastewater

The wastewater generated by the hospitals contains pathogens, bacteria, viruses, pharmaceuticals, and other hazardous contaminants. Traditional treatment methods become insufficient to remove these contaminants. In this paper, a review has been done for the treatment of hospital wastewater using electro coagulation.

Study of correlation between academic performance and quality of life among occupational therapy students

This study is designed to assess the correlation between the academic performance and quality of life among the Occupational Therapy students. To find out if a relation exists between the academic performance and quality of life of Occupational Therapy students. Method: All the samples were collected from Occupational Therapy students using Questionnaire method. Data were collected using the Student Performance Assessment and The World Health Organization Quality of Life (WHOQOL)-BREF. In our study, 245 Occupational Therapy students were participated, among the age range of 17-23 years and were assigned in four groups (Group A:- F.Y.B.O.Th, Group B:- S.Y.B.O.Th, Group C:- T.Y.B.O.Th, Group D:- Fi.Y. B.O.Th). The relation between their Academic Performance and Quality of life were assessed using the statistical analysis tools. The relation between academic performance and quality of life of occupational therapy students were observed and compared between Group A, Group B, Group C, and Group D. Results and Conclusion:-The results of our study showed that the academic performance and quality of life of the 4 assigned groups are positively correlated. If the value of one variable increases, then the value of another variable also tends to increase i.e. if the quality of life of Occupational Therapy students improves, then their academic performance also improves in similar proportion. Hence, it can be said that if the student has a good quality of life, then their academic performance will be better.

Hospital wastewater treatment by electro-coagulation process

Hospitals are significant consumers of water. The wastewater generated by the hospitals may contain pathogens, bacteria, viruses, pharmaceuticals etc. In this paper, the review has been done for the treatment of hospital wastewater containing harmful ingredients using electrocoagulation, the reuse of the same water after treatment. Electrocoagulation method is one of the effective methods for the treatment of Industrial Wastewater. Because of its low operation and maintenance cost, high efficiency, time-saving, lower sludge production without any addition of chemicals. The efficiency of electrocoagulation method mainly depends on the treatment time, the conductivity of the solution, distance between electrodes and the current density. The main objective of the study is to remove the solids present in Hospital wastewater by electrocoagulation using Aluminum (Al) and iron (Fe) electrodes. Electrocoagulation is the electrochemical process of treatment of wastewater. Hospital wastewater contains solids, BOD, COD, phenols, radioactive isotopes, pathogens such as bacteria, viruses, blood, body fluid, sweat, contaminated organs, disinfectant, pharmaceuticals as well as hazardous chemicals can be effectively removed by Electrocoagulation method. The factors which affect the electrocoagulation process are current density, treatment time, pH, the distance between electrodes, an initial concentration of the sample, a conductivity of the solution, electrode material. Hospital wastewater effluents discharge in environment may cause serious threat to the environment as well as humans and this effluents also contain solids, BOD, COD, phenols, radioactive isotopes, pathogens such as bacteria, viruses, blood, body fluid, sweat, contaminated organs, disinfectant, pharmaceuticals as well as hazardous chemicals, pathogenic microorganisms and other heavy metals and toxic chemical compounds such as Cu, Fe, Cd, Pb, Hg, Ni, Pt, Cyanide, Phenol and this type of wastewater can adversely affect ecology balance and public health. So there is a need to have effective treatment of the wastewater is a must before discharge into the river or stream.
