The influences of age hardening and HIP (Hot Isostatic Pressing) on the mechanical properties of A356 (Al 7Si 0.6 Mg) casting alloys were studied. Cast bars were homogenized, heated and maintained at a temperature of 540°C for a duration of 2 hours, followed by rapid cooling in a polymeric solution. The castings were age hardened at 180°C for a duration of 4 hours before being subjected to HIP ...

background: osteoporosis is a preventable and treatable disorder, reported with higher prevalence patients with ulcerative colitis but their relationship is controversial. osteoporosis in these patients may be attributes to corticosteroid use, malnutrition and reduced intake of calcium and vitamin d, lower levels of sex hormones, chronic inflammation and inflammatory cytokines. the aim of study...

Results Of the 826 HIP evaluated during the study period, chronic HBV infection was found in 198 HIP (23.97%), chronic HCV infection in 6 HIP (0.73%). Chronic HBVHDV coinfection was detected in 6 HIP (9.37%, of 64 HIP evaluated) and chronic HBV-HCV coinfection in 2 HIP (0.24%). The evolution of chronic HBV infection during the study period was as follows: HBs seroconversion in 8 HIP (4.04%), ch...

Arthroscopic hip surgery has become an established diagnostic and therapeutic method for addressing different hip pathologies. This paper focuses on hip arthroscopy for treating hip disorders in children under the age of 10. Arthroscopic hip surgery was performed 30 times on 24 children to address various hip pathologies. Indications were septic arthritis, benign soft tissue tumors, traumatic a...

BACKGROUND A discrepancy in leg length and femoral offset restoration is the leading cause of patient dissatisfaction in hip replacement surgery and has profound implications on patient quality of life. The aim of this study is to compare biomechanical hip reconstruction in hip resurfacing, large-diameter femoral head hip arthroplasty and conventional total hip replacement. METHOD Sixty patie...

Background: Hip fracture prevention in the elderly is of major importance with an ageing world-wide population. Elderly living in nursing homes have a particularly high rate of hip fractures. Hip protectors are a recent development in prevention of hip fracture caused by falling. The aim of this literature review was to examine if use of hip protectors are an effective nursing intervention in t...

CLINICAL QUESTION Is there evidence that hip protectors and vitamin D with calcium supplementation reduce hip fractures in the elderly? RESULTS The results are that vitamin D and calcium supplementation reduce incidence of hip fractures. Hip protectors provide some benefit in reducing hip fractures in elderly patients in residential facilities. IMPLEMENTATION Primary care providers should a...

methods: in a retrospective descriptive study, medical records of 204 hip fractured patients with the age of 60 or older who were admitted to the department of orthopedics was considered regarding routine laboratory tests. predictive values of these tests were assessed using receiver operating characteristic curve (roc).  results: the incidence of death due to hip fracture was 24%. the mortalit...

The Host Identity Protocol (HIP) is one of the more recent designs that challenge the current Internet architecture. The main features of HIP are security and the identifier-locator split, which solves the problem of overloading the IP address with two separate tasks. This paper studies the possibility of providing HIP services to legacy hosts via a HIP proxy. Making a host HIP enabled requires...
