A set  is detour monophonic convexif  The detour monophonic convexity number is denoted by  is the cardinality of a maximum proper detour monophonic convex subset of  Some general properties satisfied by this concept are studied. The detour monophonic convexity number of certain classes of graphs are determined. It is shown that for every pair of integers   and  with  there exists a connected graph  such that   and , where  is the monophonic convexity number of

Functional analysis of cemented bipolar hemiarthroplasty with medial calcar augmentation for unstable intertrochanteric fractures in elderly

Background: Intertrochanteric fracture is one of the most common fractures among the elderly osteoporotic population, constituting about 50% of hip fractures. These fractures are managed either by fixation using dynamic hip screw (DHS), proximal femur nail (PFN) or by replacement, based on the stability of fracture pattern, age of the patient, quality of bone and associated co-morbid conditions. Prosthetic replacement which is routinely done for femoral neck fractures requires modification when done for trochanteric fractures to improve stability. This study aims to analyse the short term functional outcome of cemented bipolar hemiarthroplasty with medial calcar augmentation for unstable intertrochanteric fractures in elderly.Methods: Our study includes 60 patients of age more than 70 years admitted in our institution during June 2012 to September 2016 with unstable intertrochanteric fractures. All patients operated through posterior approach to hip and cemented hemiarthroplasty with medial calcar augmentation with bone graft was done. Patients were followed up for an average of period of 2 years. Functional outcome was evaluated with Harris Hip score.Results: 28% of cases had excellent outcome. 43% of cases had good and 23% of cases had fair outcome. 2% of cases ended with poor outcome. The in-hospital mortality rate was 3.3%. The survival rate of the patients in this study at the end of one year is 85%. Conclusions: Cemented bipolar hemiarthroplasty with medial calcar augumentation can be considered as a good primary option for elderly unstable intertrochanteric fracture patients with osteoporotic bones and associated co-morbidities.

Effectiveness of Nursing Interventions on Physical and Psychological Outcome among Cancer Patients Undergoing Chemotherapy

Background: Cancer patient's undergoing chemotherapy experiences a variety of side effects which has influence on prognosis of illness, activity of daily living and the quality of life. There is a need of nursing care interventions for management and prevention of problem among cancer patients. Aim & Objectives: The present study aimed to assess the effectiveness of nursing interventions on physical and psychological outcome among cancer patients undergoing chemotherapy. Material and Methods: A true experimental study, post test only design with control group approach was conducted among 130 cancer patients undergoing chemotherapy at oncology ward of Pravara Rural Hospital, Loni (Bk), Ahmednagar, Maharashtra. Cancer patients who are 18 years old or older were selected with systematic random sampling method. Pre tested semi structured interview schedule was used to gather data. The assessment of health status before start of chemotherapy was carried out, followed by the nursing interventions was implemented based on patient needs and problems, and the post test was conducted after the period of interventions. The collected data was tabulated and analyzed using appropriate statistical methods wherever required. Results: The results revealed that the cancer patients experienced a wide range of physical and psychological problems prior to chemotherapy treatment. Cancer patients who received nursing interventions had improved post test mean scores on chemotherapy symptoms, pain and fatigue; emotional well being, anxiety and depression than the patients who received routine care, notably it was statistically significant at p<0.05 level. A significant association was observed between physical, psychological outcome variables and the socio demographic characteristics like sex, site of cancer, stage of cancer, duration of cancer, metastasis of cancer and the regimen of chemotherapy at p<0.05 level. Conclusion: This study demonstrated that the nursing interventions were well accepted by cancer patients and has significant effect towards the improvement of physical and psychological outcomes of cancer patients undergoing chemotherapy

Cashewnut sheath carbon: A new sorbent for defluoridation of water

217-222Cashewnut sheath, an agricultural waste discarded largely in India is identified for the preparation of an effective sorbent for fluoride removal. Experiments were conducted for the sorption of fluoride from aqueous solution using activated carbon from cashewnut sheath (CSC) in two phases, namely, batch studies and column studies. The influence of pH, adsorbent dose, particle size and contact time was investigated in batch studies. The adsorption process follows Freundlich adsorption isotherm. Continuous flow experiments in fixed bed columns packed with activated carbon were carried out in order to assess the feasibility of this for field applications. The carbon bed after exhaustion was regenerated with 0.1N hydrochloric acid. The influence of initial concentration of fluoride ion, flow rate, particle size and concentration of the regenerant on the performance of the column was studied. Comparative study was conducted with commercially available carbon impregnated with 2% aluminium sulphate solution. The results revealed that CSC is found to be active and efficient for fluoride removal

Fluoride Uptake Characteristics of Activated Carbon From Agricultural-waste

1039-1045Removal of excess fluoride from ground water to within the permissible limits of 1.0- 1.5 mg/L is the only way to control fluorosis. Batch and column type experiments were carried out for the adsorption of fluoride using activated carbon prepared from palm seed coat (PSCC) by dolomite process.In the batch study, influence of pH , adsorbent dose, contact time and initial fluoride concentration was investigated. Adsorption of fluoride was pH dependent and higher removal efficiencies were observed in the range of 4-8. Fluoride removal increased with dosage of carbon. A low concentration aluminium sulphate solution (2 per cent) effectively regenerated the exhausted carbon bed. The adsorption process obeyed Freundlich adsorption isotherm. The knetic studies revealed  that the forward rate constant was comparatively much higher than the backward rate constant. Continuous flow experiments in fixed bed columns were carried out with ground water in order to assess the feasibility of this carbon for field application. The performance of the carbon in fluoride removal was studied as a function of flow rate, initial fluoride level and particle size of the adsorbent. Fluoride removal increased with decreasing particle size of the carbon. The interesting feature of the study was that the defluoridation capacity increased with increase in the initial fluoride ion concentration. The pH, total alkalinity, total hardness, total dissolved solids of the treated water did not change appreciably indicating success of this technique for field application

Adsorption kinetics of <i>o</i> -cresol on activated carbon from palm seed_coat

127-131The activated carbon prepared from palm seed coat by dolomite process showed more than 95% removal of o-cresol from aqueous solution under optimum conditions. The adsorption capacity calculated by Freundlich adsorption isotherm gave 19.58 mg/g of o-cresol removal. The kinetic studies revealed the overall rate constant decrease with increasing concentration of o-cresol. The activated carbon showed reversible uptake of o-cresol and thus have a good application potential for the removal/recovery of o-cresol from aqueous solution. Film diffusion was found to be the rate limiting step. Recovery of used carbon was studied by in situ chemical regeneration technique and showed good result
