Biomass Combustion and Indoor Air Pollution in Tanzania - Bok av Doglas Benjamin - Häftad

Biomass Combustion and Indoor Air Pollution in Tanzania - Bok av Doglas Benjamin - Häftad

80% of families in Foo Village, Hai District Tanzania use simple ¿three stones stoves¿ (wood fires stoves), normal charcoal stoves, improve charcoal stove, improved wood stove and kerosene stoves. Aabout 77.8 % house wives time is spent in the indoor environment. Using additive risk model analysis, hourly indoor concentration is PM10 during cooking period and ranges from 1931 mg/m3 to 4949 mg/m3, which exceeds that of WHO recommended value of 150mg/m3 for 24 hours. The Coborn Dioxide concentrations..

Potable water coverage of Adea Berga District - Bok av Alemu Tolera - Häftad

Potable water coverage of Adea Berga District - Bok av Alemu Tolera - Häftad

Ethiopia has 12 river basins with an annual runoff volume of 122 billion cubic m3 of water and an estimated 2.6 - 6.5 billion m3 of ground water potential. This corresponds to an average of 1,575 m3 of physically available water per person per year, a relatively large volume. However, due to large spatial and temporal variations in rainfall and lack of storage, water is often not available where and when needed. Only about 3% of water resources are used, of which only about 11% (0.3% of the total)..

Effect of Strain Rate on the Shear Strength of Rock Pile Materials - Bok av Kojo Anim - Häftad

Effect of Strain Rate on the Shear Strength of Rock Pile Materials - Bok av Kojo Anim - Häftad

Understanding creep behavior in rock piles under both dry and moist conditions will help to evaluate long-term stability of rock piles. The effect of compaction densities (1700 kg/m3 and 1850 kg/m3) on moist (8% water content) samples were also investigated for four shearing rates (0.5 mm/min, 0.05 mm/min, 0.0275 mm/min and 0.005 mm/min). Normal stresses of 160 kPa, 480 kPa and 750 kPa were used. The obtained internal friction angles versus rate of shear deformation were plotted in a semi-logarithmic..

Induced Mutation in M3 Generation of Kharif Sorghum - Bok av Jaykumar Deshmukh - Häftad

Induced Mutation in M3 Generation of Kharif Sorghum - Bok av Jaykumar Deshmukh - Häftad

Sorghum is grown in India in places with 500 to 1000 mm of yearly rainfall and temperatures ranging from 26 to 32 0C. Plains and plateaus below 100m elevation provide good opportunities for effective crop cultivation in two seasons: Kharif as a rainfed crop and Rabi as a protected irrigated crop, with 60 and 40 percent cultivation, respectively. Sorghum [Sorghum bicolor (L.) Moench] is a diploid (2n = 2x = 20) cross pollinated crop from the poaceae family. After wheat, maize, rice, and barley, sorghum..

Clinical applicability of Mini Implant as Anchorage in Orthodontics - Bok av Shruti Mittal - Häftad

Clinical applicability of Mini Implant as Anchorage in Orthodontics - Bok av Shruti Mittal - Häftad

Mini implants, also known as temporary anchorage devices (TADs), are small screw-like devices that are temporarily anchored into the jawbone to provide additional support during orthodontic treatment. Mini implants are usually made of titanium, which is a biocompatible material that allows the implant to fuse with the bone.Mini implants have become increasingly popular in orthodontic treatment because they can provide additional anchorage without relying on the patient's teeth for support. This allows..

EXTRA ALVEOLAR MINI-IMPLANTS - Bok av Sai Sree Sindhu Drona - Häftad

EXTRA ALVEOLAR MINI-IMPLANTS - Bok av Sai Sree Sindhu Drona - Häftad

Orthodontic mini-screw is a boon both to patient and the Orthodontist. Nowadays, extra alveolar mini screws have gained increasing popularity to overcome the shortcomings of conventional inter-radicular mini-screws These are the mini-screws which are placed in extra- alveolar sites like infra-zygomatic region, buccal shelf area and palatal regions. They offer the orthodontist to treat complex malocclusion with elaborate tooth movements like en masse distalization expansion, mesialization, intrusion..

Implant Designs and Stress Distribution - Bok av Raziya Perween - Häftad

Development of an ideal substitute for missing tooth has been a major aim for dental practitioner for millennia. The goal of modern dentistry is to restore the patient tooth to normal contour, function, comfort, esthethic and speech. Implant dentistry is unique as it achieve all goals. Dental implant are biocompatible screw like titanium that are surgically placed into the maxilla and mandible for replacing missing tooth. Implant design (material, dimension and structure) is important factor affecting..

Design and construction of a palm Kernel oil extraction machine - Bok av Vitalis-Mary Maduka Omeche - Häftad

Design and construction of a palm Kernel oil extraction machine - Bok av Vitalis-Mary Maduka Omeche - Häftad

Palm kernel oil is an important element of African cookery and rural industry. The traditional method of oil extraction currently used in rural area is strenuous, time consuming and inefficient. To mechanize the oil extraction process, a screw press implement for the multi-function platform diesel engine was designed and fabricated. This device will be capable for processing in excess of 100kg/hr of palm kernels, and expel kernel cake with no greater than 15% oil content for sub-Sahara region in..

The Radon concentrations in some dwellings of Mandya, India - Bok av Narasimhamurthy K. N. - Häftad

The Radon concentrations in some dwellings of Mandya, India - Bok av Narasimhamurthy K. N. - Häftad

The measurement of 222Rn and 220Rn concentrations in air was carried out in 50 dwellings belonging to 20 locations in and around Mandya city, Karnataka,India. Annual mean values of 222Rn and 220Rn concentrations were found to be 22.4 1.5 and 24.1 1.8 Bq/m3, respectively. The total annual effective dose received by the general public due to radon and thoron was found to be 1.36 0.08 mSv/y. The doses to different organs and tissues were calculated using the International Commission on Radiological..
