Traffic accidents are still one of the serious problems faced by Indonesian Government. Based on traffic accident data from Corps Republic Indonesia number in 2020 is 100,028 incidents and deaths due to 23,529 people. caused several factors such as vehicles, human error road users, conditions environment. Road geometry factor that contributes high value risk accidents. One effort reduce identif...

assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. in the present study, statistical analyses are performed on some data col...

behaviors of stress corrosion cracking (scc)in martensitic stainless steel(aisi 420) and low carbon austenitic stainless steel (aisi 316l) have been compared under different conditions of temperature, environment (mgcl2), and strain rate. the results show that decreasing strain rate has detrimental effect on mechanical properties of both steels, including their strength and ductility. fractogra...

background: a rare and devastating complication following anterior cruciate ligament (acl) revision reconstruction is femoral fracture.    case presentation: a 35-year old male soccer player with a history of acl tear from the previous year ago, who underwent arthroscopic acl reconstruction and functioned well until another similar injury caused acl re-rupture. revision of acl reconstruction wa...

Fracture mechanics is a field of solid mechanics interested with the behaviour of materials under certain loads their distribution and finally the fracture criteria of given materials.This Paper evaluates size dependency of fracture parameters, fracture energy (Gf) and fracture process zone effective length (Cf) of concrete concluded as per Bazant’s size effect method. Fracture mechanics standa...

introduction: vertical root fracture inevitably leads to tooth extraction. thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. this study aimed to assess the fracture resistance of roots following the application of different sealers including epiphany, iroot sealer and ah-plus. methods and materia...

background supracondylar fracture of the humerus is the most common elbow injury that requires reduction and immobilization in the proper position to :union:. there are a few reports regarding the position of the forearm immobilization on elbow cosmetic outcome. objectives this study aimed to compare two modes of the forearm, supination and pronation in elbow deformity incidence after closed re...

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and...

Abstract This study reviews the state of art in structural design and corresponding mechanical behaviours composite vascular grafts. We critically analyse surface matrix designs composed layered, embedded, hybrid structures along radial longitudinal directions; materials manufacturing techniques, such as tissue engineering use textiles or their combinations; grafts terms physical–mechanical pro...

background and aim: clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. the aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (psp) and cbct in the detection of horizontal root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experim...
