Investigation on liquid flow characteristics in microtubes

The fundamental understanding and prediction of liquid flow characteristics in microscale are important to control the performance of microfluidic devices. However, fundamental questions about liquid flow characteristics in microscale have not been settled yet and systematical investigation is needed. A systematical investigation on liquid flow characteristics through microtubes with diameters varying from 44.5–1011 μm and relative roughness in the range 0.02–4.32% in the Reynolds number range 29–11,644 was performed in this work, using water as working fluid. Experimental results indicated that early transition occurred when the diameter was smaller than 1000 μm, the transitional flow characteristics for smooth microtubes differed from rough microtubes and the friction factor in turbulent region for rough microtubes was larger than conventional theory. Moreover, a parameter α was proposed to describe the characteristic of microtube. The characteristic parameter was used to calculate the critical Reynolds number and the friction factor in turbulent region for microscale

Building Specialized Nursing Practice Capacity in Bangladesh: An Educational Program to Prepare Nurses to Care for Oncology and Bone Marrow Transplant Patients in Dhaka, Bangladesh

In 2012, the Minister of Health and other leaders in the Bangladesh government approached Massachusetts General Hospital to establish the country’s first bone marrow transplant program at Dhaka Medical College Hospital to serve the needs of the people of Bangladesh. Stated goals of this collaboration included a broad focus on the care of oncology patients with a specific emphasis on care of patients with hematologic malignancies and of women with gynecologic cancers. The purpose of this article is to describe the international nursing collaboration between Massachusetts General Hospital, Simmons College, the AK Khan Healthcare Trust in Dhaka, and Dhaka Medical College Hospital that was established to share nursing knowledge and to build specialized professional nursing capacities to deliver high-quality cancer care in the public sector. Over the past 3 years, through the educational programs that have been developed within this collaboration—the Enhanced Specialized Nurse Training Program—the Bangladeshi nurses have received continuing professional development based on Western standards of nursing and have been offering nursing care to patients who have undergone chemotherapy and bone marrow transplantation. The challenges, opportunities, and outcomes of this international collaboration have been highly rewarding and mutually beneficial
