The hydraulic bulge test (HBT) method is proposed to determine material tensile strengths. The basic idea of HBT is similar to the small punch test (SPT), but inspired by the manufacturing process of rupture discs-high-pressure hydraulic oil is used instead of punch to cause specimen deformation. Compared with SPT method, the HBT method can avoid some of influence factors, such as punch dimensi...

BACKGROUND Multidrug punch cards are frame cards with 28 plastic cavities filled with a patient's oral solid medication. They are used in primary care to facilitate medication management and to enhance adherence. Main criticism concerned handling difficulties and fading knowledge about medication of patients using them. This study aimed at exploring daily use, preferences, and adherence of prim...

Pneumatic retinopexy is increasingly recommended to treat some patients with retinal detachment to avoid the complication of induced refractive changes sometimes associated with scleral buckling procedures. Prospective evaluation of refractive changes after scleral buckling procedures was performed in 75 eyes of 69 patients. Encircling scleral buckles caused an average increased axial length of...

purpose: to compare clear corneal incision and scleral tunnel incision in terms of intraocular pressure (iop), post-operative inflammation, induced astigmatism, and corneal edema in phacoemulcification. methods: this non-controlled clinical trial was conducted on 78 eyes with senile cataract. a clear corneal incision was made in 40 eyes and a scleral tunnel incision was made in 38 eyes. all eye...

BACKGROUND Onchocerciasis is endemic in the Imo River Basin, Nigeria. This study was aimed at assessing the prevalence and intensity of microfilaria of Onchocerca volvulus in the area. METHODS A cross-sectional study was carried out in the Okigwe Local Government Area, Imo State, Nigeria. Two skin snips (one from the waist and another from the shoulder) were taken from 1024 individuals examin...

OBJECTIVE To determine the relation between retinal tears and scleral ectasia. DESIGN Prospective study. SETTING University-based referral practice in Montreal. PATIENTS Fifty-seven consecutive patients with primary rhegmatogenous retinal detachments undergoing scleral buckling surgery. Patients with a history of trauma or previous cryotherapy, laser treatment or other vitreoretinal proce...

BACKGROUND Partial thickness sclerectomy is the most commonly employed scleral shortening technique used in conjunction with pars plana vitrectomy in the repair of myopia-associated macular holes in patients with staphyloma. Recently, scleral shortening induced through scleral invagination has been advocated as an adjunct in retinal translocation surgery. OBJECTIVE To determine whether a corr...

A small punch test is one of the innovative methods that can be used to evaluate the properties of a material without destructive harm to the in-service component. Conventionally identifying material properties by a uniaxial test is widely applied to engineering. How the properties obtained from a small punch test can be applied with the same utility has been a goal. In 2006, European Code of P...
