In the green manufacturing system that pursues the reuse of used products, the residual value of collected used products (CUP) hugely affects a variety of managerial decisions to construct profitable and environmental remanufacturing plans. This paper deals with a closed-loop green manufacturing system for companies which perform both manufacturing with raw materials and remanufacturing with co...

The temperatures of standard glassware and ceramics are nearly impossible to tell just by sight. Therefore, burns from touching heated surfaces are common in the laboratory and in the kitchen. The sol-gel process is a safe method to create foam under ambient conditions. Adding different chemical compounds causes the foam to have varying physical and chemical characteristics. This project focuse...

Objective To teach students a fun way to observe root growth and gravitropism by creating a time-lapse movie. Assign readings concerning seedling morphology, growth and gravitropism from the text or other sources; or have students find sources of information to use for class preparation. Curriculum Considerations Depending on your goals and resources, you can alter the exercise to study factors...

PURPOSE The aim of this prospective study is to validate a vector arithmetic method for measuring acetabular cup orientation after total hip arthroplasty (THA) and to verify the clinical practice. MATERIALS AND METHODS We measured cup anteversion and inclination of 123 patients after cementless primary THA twice by two examiners on AP pelvic radiographs with a vector arithmetic method and com...

PURPOSE To evaluate the optic nerve head (ONH) parameters of primary open-angle glaucoma (POAG) patients with and without diabetes and to investigate the effect of the metabolic control of diabetes on ONH topography. MATERIALS AND METHODS A study group of 60 eyes of 60 POAG patients with type 2 diabetes mellitus and a control group of 41 eyes of 41 POAG patients without diabetes were recruite...

BACKGROUND The overall prognosis for cancers of unknown primary (CUP) is poor, median overall survival (OS) being 6-12 months. We evaluated our multicentric retrospective experience for CUP administered docetaxel and cisplatin combination therapy. MATERIALS AND METHODS A total of 29 patients that were pathologically confirmed subtypes of CUP were included in the study. The combination of doce...

BACKGROUND Breast conservative surgery (BCS) followed by radiotherapy is the standard approach in management of stage I-II breast cancer. Several factors can affect cosmetic outcomes. The aim of this study was to evaluate the cosmetic results of BCS and influencing factors in the Iranian Breast Cancer Research Center. MATERIALS AND METHODS Patients who had undergone BCS were included. Photogr...

PURPOSE To evaluate the usefulness of navigated acetabular cup fixation for total hip arthroplasty in patients with acetabular deformity or revision total hip arthroplasty. MATERIALS AND METHODS This study enrolled 28 patients with at least 12 months' follow-up. The safe zone of the acetabular cup was defined as 40°±10°in inclination and 15°±10°in anteversion. The authors used the navigation ...

PURPOSE The purpose of this study was to assess the squeaking incidence and risk factors after primary ceramic-on-ceramic total hip arthroplasty (THA) in Asian patients using meta-analysis. MATERIALS AND METHODS We performed a meta-analysis of published data on the squeaking incidence and risk factors from 2000 to 2013. Eight studies in Asians were analyzed for both squeaking incidence and ri...
