Potential, challenges and prospects of rabbit farming in urban and peri-urban areas of Dodoma city, Tanzania

[EN] This study highlights the current status of rabbit production, potential challenges facing the industry and the prospects for rabbit farming in Dodoma city, Tanzania. Data from 60 individuals keeping rabbits were collected through a structured questionnaire and direct observation. Results showed that 60% of the respondents were men and 40% women. Rabbits were kept mainly as a source of meat for families and income generation. Main sources of rabbit stock were local breeders (55%) and missionaries (25%), while the remainder were from agricultural institutes. The dominant rabbit breeds reared were California white (50%), New Zealand white (30%), Chinchilla (10%) and Dutch (10%). Ninety-five percent of the farmers kept rabbits in cages, while 5% confined them at night and let them out during the day to forage for feed. Fifteen percent of the respondents fed commercial rabbit pellets, 5% vegetables and kitchen waste only, whereas 80% fed both rabbit pellets, vegetables and kitchen waste. The number of rabbits kept by an individual farmer ranged from 5 to 180, with mean stock size of 22.80±11.20 (mean±standard deviation). Rabbits were sold at 8 to 12 wk of age and each rabbit was sold for 20 000 to 30 000 Tanzanian shillings (8.00 12.00 USD). Major challenges in rabbit production were lack of feed resources, lack of readily available market, poor quality of breeding stock, low knowledge of rabbit production techniques and lack of technical support from extension services. Although rabbit farming in Dodoma is carried out at subsistence level, it is associated with a decrease in poverty among urban and peri-urban farmers. In conclusion, rabbit production in urban and peri-urban areas of Tanzania has the potential to contribute to food and nutrition security and poverty alleviation, thus improving living standards.Moto, E.

Peranan Fase Amorf Si3n4 Pada Nanokomposit Nc-tin/a-si3n4 Dalam Meningkatkan Kekerasan Dan Stabilitas Termal

The role of Si3N4 amorphous phase in nc-TiN/a-Si3N4 nanocomposites will be shown and compared with polycrystalline ZrN/Ni which has no such amorphous phase (non-composites). The presence of amorphous phase Si3N4 increases the hardness of film as well as the toughness of the bulk nanocomposites under indentation load. It has been observed that nc-TiN/a-Si3N4 nanocomposites films has higher thermal stability than ZrN/Ni polycrystalline films

Pembuatan Paduan (Ti1-xalx)n Dengan Teknik Plasma Cvd Dari Bubuk Alcl3, Gas N2 Dan H2, Serta Larutan Ticl4

    The substitution of Ti atoms by Al atoms in TiN lattice sites to form (Ti1-xAlx)N is clearly demonstrated by the coatings which were deposited on steel substrate and using plasma CVD technique. The presence of Al atoms in TiN lattice site is shown by means of XRD and EDX techniques: lattice parameters decreasing of TiN as the fraction of Al increases (XRD) and precipitation of hexagonal AlN phase (XRD) as the fraction of Al exceeding 0.8 (EDX). The hardness of these coating are just around 30 GPa, which is beyond the values reported in literatures

Prosedur Pengukuran Kekerasan Yang Benar Pada Nanokomposit Nc-tin/a-si3n4

Hardness of nc-TiN/a-Si3N4 nanocomposites which was determined by using two methods of measurements i. e. depth sensing method and remaining plastic indentation area that were magnified by using SEM (Scanning Electron Microscope) lie in the good agreement. The hardness value is not influenced by the biaxial and residual compressive stress. The measurement of the biaxial stress on the substrate shows a very small value of biaxial stress as well as the constant hardness and crystallite size against annealing temperature. Therefore, the reported hardness value here is theintrinsic value that depend on its microstructure properties

Acute Genetic Manipulation of Neuronal Activity for the Functional Dissection of Neural Circuits — A Dream Come True for the Pioneers of Behavioral Genetics

This review summarizes technical development of the functional manipulation of specific neural circuits through genetic techniques in Drosophila. Long after pioneers ’ efforts for the genetic dissection of behavior using this organism as a model, analyses with acute activation of specific neural circuits have finally become feasible using transgenic Drosophila that expresses light-, heat-, or cold-activatable cation channels by xxx/upstream activation sequence (Gal4/UAS)-based induction system. This methodology opened a new avenue to dissect functions of neural circuits to make dreams of the pioneers into reality

Perbedaan Model Pembelajaran Problem Solving dan Discovery Learning ditinjau dari Kemampuan Berpikir Kritis Peserta Didik

Penelitian ini bertujuan untuk mengetahui perbedaan model pembelajaran Discovery learning dan Problem solving ditinjau dari keterampilan berpikir kritis peserta didik kelas 4 sekolah Dasar pada pembelajaran tematik. Sampel penelitian diambil menggunakan teknik probality yaitu dengan area sampling atau cluster sampling sehingga jumlah sampel penelitian berjumlah 51 peserta didik. Metode penelitian yang dugunakan adalah eksperimen semu (Quasi Eksperimental Research). Teknik analisis data menggunakan teknik deskriptif dan uji T. hasil penelitian menunjukan bahwa penggunaan model pembelajaran Problem solving lebih efektif dalam meningkatkan keterampilan berpikir kritis dari pada model pembelajaran Discovery learning. Hal tersebut dapat dibuktikan dengan hasil akhir yang diperoleh dari kelas eksperimen dengan jumlah peserta didik (N) sebanyak 26 peserta didik dengan nilai rata-rata sebesar 61,32, sementara pada kelas kontol diperoleh nilai rata-rata sebesar 66,85 dengan (N) sebanyak 25 peserta didik. Hasil uji T diperoleh nilai signifikansi pada F sebesar 2,589 dan nilai sig 0,024 < 0,050, maka Ho ditolak dan Ha diterima yang artinya bahwa terdapat perbedaan yang signifikan dalam penerapan model problem solving dan discovery learning ditinjau dari keterampilan berpikir kritis peserta didik kelas 4 SD dalam pembelajaran temati
