Background: High-resolution estimates of HIV burden across space and time provide an important tool for tracking and monitoring the progress of prevention and control efforts and assist with improving the precision and efficiency of targeting efforts. We aimed to assess HIV incidence and HIV mortality for all second-level administrative units across sub-Saharan Africa. Methods: In this modelling study, we developed a framework that used the geographically specific HIV prevalence data collected in seroprevalence surveys and antenatal care clinics to train a model that estimates HIV incidence and mortality among individuals aged 15–49 years. We used a model-based geostatistical framework to estimate HIV prevalence at the second administrative level in 44 countries in sub-Saharan Africa for 2000–18 and sought data on the number of individuals on antiretroviral therapy (ART) by second-level administrative unit. We then modified the Estimation and Projection Package (EPP) to use these HIV prevalence and treatment estimates to estimate HIV incidence and mortality by second-level administrative unit. Findings: The estimates suggest substantial variation in HIV incidence and mortality rates both between and within countries in sub-Saharan Africa, with 15 countries having a ten-times or greater difference in estimated HIV incidence between the second-level administrative units with the lowest and highest estimated incidence levels. Across all 44 countries in 2018, HIV incidence ranged from 2·8 (95% uncertainty interval 2·1–3·8) in Mauritania to 1585·9 (1369·4–1824·8) cases per 100 000 people in Lesotho and HIV mortality ranged from 0·8 (0·7–0·9) in Mauritania to 676·5 (513·6–888·0) deaths per 100 000 people in Lesotho. Variation in both incidence and mortality was substantially greater at the subnational level than at the national level and the highest estimated rates were accordingly higher. Among second-level administrative units, Guijá District, Gaza Province, Mozambique,

In this work, the preparative conditions for optimizing growing carbon nanotube thin films on silicon wafers using an in-house chemical vapor deposition system was evaluated. We found that, when acetylene was used as the carbon source and nickel as the catalyst, the amount of carbon nanotubes grown on the silicon wafers was increased when the growth temperature was decreased from 800°C to 600°C. The carbon nanotubes were then characterized by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and tunneling electron microscopy (TEM). The results show the obtained carbon nanotube thin films were mainly composed of multi-walled carbon nanotubes.

In the case of multi-echelon and multi-item inventory systems, the option of accelerated lead time can reduce the inventory cost of the system but on the other hand increase the crashing cost. We utilize an optimization model to show the impact of lead time acceleration by considering component commonality. These imply that lead time is controllable and products taken into example consist of unique and common components. We use some hypothetical data to test the model. We extend the model for two-echelon inventory system by considering controllable lead time and service level constraint and adding the concept of component commonality in a multi-product's items case. The results show that most of demand is fulfilled by unique components for both products. Subsequently, the lead time of common component becomes not significant (=0).
