parameters are cutting speed of 180 m/min, feed rate of 0.08 mm/rev, cut of depth of 0.15 mm and gives surface roughness of Ra= 0.23 micron. [16] S.Chinchanikar et al. [2015] investigated the effect of minimum quantity lubrication (MQL) on hard turning of AISI 4340 steel at 55 HRC using TiSiN-AiAlN coated carbide tool. By multi objection optimization of parameter in dry and MQL cutting conditions it is observed that hard turning under MQL produce a significant improvement in tool life by almost 30% I comparison to dry cutting and also lowering cutting forces and surface roughness. Optimum cutting conditions of cutting speed= 136 m/min, feed rate= 0.088 mm/rev, depth of cut= 0.3 mm were observed. [17] P.Netake et al. [2015] developed a statistical model to predict the cutting force and surface roughness during hard turning of AISI 52100 alloy steel at 62 HRC under minimum quantity lubrication using PVD coated nanocrystalling TiSiN-AiAlN coated carbide tool. It was…

Material and Method For the present study, total 1000(500 males and 500 females) asymptomatic, healthy adults, residing in Teerthanker Mahaveer University of cosmopolitan origin with age over 18 years old with no diagnosed history of knee arthropathy and spinal deformity and a written informed consent was taken from the subjects. The measurements were taken between 2 to 5 p.m. to remove the inconsistencies due to diurnal variations. Sampling Method - : Purposive and Judgment sampling methods…

As the owner of a popular clothing establishment, it came to my attention during the weekly staff meeting that customer satisfaction was a concern the employees were voicing. This discussion led to the potential of performing a survey throughout our ten locations, which serve over two-hundred customer per day. The quandary is how we build this sample. When gathering satisfaction data from a population, such as the customers of a popular clothing store, surveys are very beneficial. However,…

relaxation; receptive music therapy has correlations with the reduction of blood pressure, muscular tension, and perceived pain. It has relations with the stabilization of heart rate, endorphin levels, and brain waves, as well as improvement towards immune systems and body movements (Lepke-Sims). PLOS ONE, a peer reviewed scientific journal by the Public Library of Science, has further reveal the significant physiological effects of receptive music therapy; it dramatically reduces stress in…

Also, group (A) showed statistical significant decrease in number of intubation attempts in comparison to group (B) denoting easier nasal intubation attempts in group (A). Patients in group (A) showed decrease in number of patients developed hypoxia during intubation attempts in comparison to Group (B). There were no statistically significant differences between both groups regarding pharyngeal trauma. Group (A) showed decrease of numbers of need to do corkscrewing in comparison to Group (B),…

or have other important appointments. In addition, the place should be accommodating for the students. I will be testing two different groups: one, being the at risk students and another the control group. The control group will be students who are attending a SI session, but a lower quality one. This means that in the control group, students would not be receiving the same benefits that a student would have in the experimental group. Additionally, the students would not receive instructions to…

electromyogram activity (i.e. time of muscle contraction) (dependent), and the use of non-dominant arms for contraction (control). In considering strength in the dominant forearm due to daily usage, the non-dominant arm was chosen to avoid any differences in strength between the participants. Similarly, the participants were not told about the purpose of the experiment so that they would not try to alter their performance in order to confirm their own hypothesis regarding CHO and grip strength…

between family income and employment status. In conjunction, both studies includes smoking as a variable to be compared between participants with periodontitis and healthy individuals. Although Vettore et al. (2003) found no correlation between other demographic factors, smoking was one aspect that showed slight statistical significant difference with the majority of smokers belonging to the group of periodontitis patients. However, this non-significant comparison in a study based on a…

Nevertheless, there was statistical significance, between males and females on their patriotism scores. This could be due to the fact that males, generally, are more pleased with the election results and feel more patriotic at this time. But, it could also mean that males, in general, are more patriotic than females. The biggest limitation of this survey is the external validity. I used my Facebook to recruit participants, which is textbook convenience sampling that does not allow me to make…

expert will use their expertise to specify the parameters for the prior distribution during a Q&A session with statisticians. After that, statisticians will integrate all experts’ outputs and form a single prior distribution for the parameters. Several studies have been done on eliciting single parameter. However, In clinical trials, researchers need to elicit a joint prior distribution for at least two parameters (e.g. outcome rate with standard care and with improved care). Previous work had…
