Electromagnetic radiation still is a new and exotic option in food and beverage processing, though it gradually is finding niches in various applications as research engineers overcome the practical barriers to commercial use. From relatively benign radio waves to highly destructive gamma waves, electromagnetic radiation has been used for everything from drying crackers to meat sterilization. T...
There has been a long history of subjecting marginalized women to forced and coerced sterilization. In recent years, the practice has been documented in countries in North and South America, Europe, Asia, and Africa. It has targeted women who are ethnic and racial minorities, women with disabilities, women living with HIV, and poor women. A handful of courts have issued decisions on the recent ...
BACKGROUND Long-acting reversible contraceptives such as intrauterine devices (IUDs) are highly effective in preventing pregnancy, cost effective, and increasing in popularity. It is unclear whether changes in IUD use are associated with changes in rates of irreversible tubal sterilization. In this analysis, we evaluate changes in rates of tubal sterilization, insertion of copper or levonorgest...

Arabidopsis thaliana (Arabidopsis) seedlings often need to be grown on sterile media. This requires prior seed sterilization to prevent the growth of microbial contaminants present on the seed surface. Currently, Arabidopsis seeds are sterilized using two distinct sterilization techniques in conditions that differ slightly between labs and have not been standardized, often resulting in only par...
فرض کنید $ g $ یک گراف ساده، $ c(x) $ حلقه ای از تمام توابع پیوسته ی حقیقی مقدار روی فضای کاملاً منظم هاسدورف $ x $ و $ gamma(c(x)) $ گراف مقسوم علیه-صفر در حلقه ی $ c(x) $ باشد، در این پایان نامه ارتباط بین ویژگی های گراف $ gamma(c(x)) $، ویژگی های حلقه ی $ c(x) $ و ویژگی های توپولوژیکی فضای $ x $ بررسی می شود. سپس نشان داده می شود عدد خوشه ای ...
PURPOSE The complex miniature architecture of dental burs and endodontic files makes precleaning and sterilization difficult. Devising a sterilization protocol for endodontic files and dental burs requires care, and some have suggested that these instruments be considered single-use devices. One purpose of this study was to determine the effectiveness of various sterilization techniques current...
Millions of patients worldwide remain inadequately treated for bone defects related to factors such as disease or trauma. The drawbacks of metallic implant and autograft/allograft use have steered therapeutic approaches towards tissue engineering solutions involving tissue regeneration scaffolds. This study proposes a composite scaffold with properties tailored to address the macro- and microen...
Tubal sterilization is an increasingly common method of contraception. Although pregnancy after sterilization is uncommon, it can occur and may be ectopic. It is widely believed that any pregnancies after tubal sterilization will generally occur during the first year or two year after the procedure. Surprisingly, failures are not limited to the first year or two, but continued to appear at each...
The functional replacement of tendon represents an unmet clinical need in situations of tendon rupture, tendon grafting, and complex tendon reconstruction, as usually there is a finite source of healthy tendon to use as donors. The microfibrous architecture of tendon is critical to the function of tendon. This study investigates the use of electrospun poly(ɛ-caprolactone) scaffolds as potential...
