Published: June 2019

The paper reports the study of peculiarities in the roughness formation of conjugate cylindrical and end surfaces of machinery at their simultaneous grind-ing with the disk periphery and the end.
The analytical dependences for the computation of altitude and step parameters of surface roughness at simultaneous grinding with disk periphery and butt are obtained the authenticity of which is confirmed in the course of experimental investigations. It is defined that altitude and step roughness parameters of cylindrical surfaces and end surfaces conjugate with them after their simultaneous grinding may differ up to 2-3 times. Lesser roughness is formed on end surfaces which is explained by the large number of disk grain tips contacting with given surfaces of a blank. The roughness step parameters of ground surfaces are influenced considerably by a rounding radius of abrasive grain tips at that the average step of unevenness along a middle line Sm is threefour times greater than the average step S on tips.
It is shown that a considerable impact of abrasive tool characteristics and time of surface processing with a grinding disk upon parameters of roughness in conjugate surfaces of parts.
Recommendations scientifically substantiated are formulated on the technological support of surface roughness parameter aggregate at simultaneous grind-ing with the disk periphery and the end.

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.

Introduction: Total Knee Replacement (TKR) is an increasingly common treatment for severe knee osteoarthritis and the main indication is pain. Subjective factors affect the way in which individuals express their real-life experiences thus, this study aimed in bringing to the fore the personal perspective and interpretation of clients with (TKR). The objective of this study was to explore the lived experiences of clients with total knee replacement.
Methodology: Phenomenological qualitative research design was used where participants were selected from hospital record of Tribhuwan University Teaching Hospital and Nepal Orthopedic Hospital of Kathmandu. Based on the lived phenomenon, similar sharing of experiences from seven among nine participants with the in-depth interview was obtained. The data was collected for 2 months period where data analysis went simultaneously to reveal the concepts. Then the interview was transcribed manually following the thematic analysis phases of Gibson.
Results: The results indicated that most (5/7) expressed their ability to walk independently. Four clients (4/7) reported they could perform household chores and had no difficulty travelling in vehicles. Despite those positive results, all respondents (7/7) after TKR faced difficulties sitting down and the majority (6/7) faced difficulty climbing stairs. Four had difficulty in standing up and lying. Three had queries about the treatment process; swelling of lower legs and life of the implant.
Conclusion: The emerged five themes: impact of the treatment regimen, mobility issues, treatment modalities, supportive environment and inadequate health counselling revealed that although there is mixed result of treatment outcome, all respondents are satisfied as they got rid of the continued severe knee pain; hence, the respondents are following some safety and precaution measures for the better outcome. Adequate health counselling emphasizing in the rehabilitation programmes after TKR should be prioritized.

Objective: Hypertension is one of the common non-communicable health problems. While pharmacologic intervention is the most efficient way to control hypertension; non-adherence to medication is accounted as a significant cause for complications. This study was to address and to determine the magnitude of non-adherence among hypertensive patients by summarizing the associated risks factors among patients in community level.
Method: This is a cross sectional study conducted on hypertensive patients who visited the community health clinic at Dhading, Nepal on 9th and 10th June 2018 using a pre structured questionnaire. Patients were sampled by nonprobability purposive sampling method. Effect of age, gender, marital status, employment, education level, presence of diabetes, cerebrovascular disease, current smoker, and family history of hypertension were analyzed by compliance of antihypertensive drugs using frequency distribution, chi-square test, and logistic regression. For all of the analysis p value <0.5 was considered as significance.
Results: 150 patients were included in the study, out of whom 48 patients were found adherent and 102 patients non-adherent to antihypertensive medication. Out of total population 46% (n=69) were male and 54% (n=81) were female with no significant difference between compliant and noncompliant groups (OR= 1.512, p-=0.292). Mean age of patients in complaint group was 57 years and in non-compliant group was 52 years with odds ratio of 0.959 (p= 0.004, 95% C.I =0.933-0.987). However, there was no significant effect of marital status, employment status, and family history of hypertension on adherence to anti-hypertensive medication. Presence of diabetes had significant effect on adherence to medication (OR= 8.494, p= 0.014). The most common reason for non-adherence was the fear of getting stuck with medication for lifetime (n=31, 30.3%) followed by the use of ayurvedic/home remedy (n=27, 26.5%), unaware of complications (n=16, 15.7%), life style modification (n=14, 13.7%), and financial weakness (n=9, 8.8%). Pearson’s correlation of these reasons was between -1 to 0 with p value <0.5.
Conclusion: Fear of taking medication lifelong was the major reason for non-adherence; however, age and comorbid health conditions like diabetes have a significant effect on adherence to medication. Health care awareness and counseling can help these patients to overcome the fear of taking medication for lifetime, which can increase the medication compliance rate.

Introductions: Many different techniques of reduction of acute anterior shoulder dislocation have been described. The aim of this study was to evaluate the effectiveness of external rotation method for reduction of acute anterior shoulder dislocation.
Methods: Fifty-one patients with acute anterior shoulder dislocations with or without greater tuberosity fracture were reduced during a period from January 2013 to January 2015. The external rotation method was used as an initial reduction method performed by orthopaedic surgeon on call or residents. Data sheets completed by the orthopaedic surgeon on call or residents were evaluated with regard to the type of dislocation, the effectiveness of the procedure in achieving reduction, the need for premedication, the ease of performing the reduction, and complications, if any.
Results: There were 42 male and nine female patients between 18 to 78 years. Among 51 patients, 49 had successful reduction. No premedication was required in 33 patients who had a successful reduction, and the average time required for reduction in 23 patients was within two minutes whereas 20 patients reduced within five minutes. Only four patients reported severe pain during the process of reduction. The method was not successful in two patients with subcoracoid dislocation associated with displaced fracture of the greater tuberosity.
Conclusions: External rotation method is reliable, safe, simple and relatively painless method for reduction of acute anterior shoulder dislocation.
