We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum conductivity was approximately 18500 W/m/K at 10 K. This spring constant 1/43 of that single thick wire with the same cross-sectional area room temperature. realized these performances by utilizing purity aluminum (99.9999 %, 6N) stranding many thin wires are 0.15 mm in diameter. electrica...
Fifty Suffolk-crossbred wether lambs, with an initial live weight of 29 +/- 2.1 kg, were allocated to one of five concentrate-based diets formulated to have a similar fatty acid content (60 g/kg DM), but containing either linseed oil (high in 18:3n-3); fish oil (high in 20:5n-3 and 22:6n-3); protected linseed and soybean (PLS; high in 18:2n-6 and 18:3n-3); fish oil and marine algae (fish/algae;...
در این پایان نامه ابتدا لیگاند 6 دندانه (6n) تحت واکنش تراکمی و با استفاده از سالسیل آلدئید و2-استیل فوران سنتز گردیده و سپس در حضور برخی از یون های فلزات قلیایی (li+ و+na)، قلیایی خاکی (mg2+ ،sr2+ وba2+) و فلزات واسطه ( mn2+ ،ni2+ ،cu2+ ،zn2+ وcd2+) کمپلکس های باز شیف- فلز تهیه شدند. لیگاند ها و کمپلکس های تهیه شده، با استفاده از تکنیک های ft-ir، 1h nmr، 13c nmr، dept وmass وchn مورد شناسایی ق...
The starvation effects on the fatty acids composition of the digestive gland of the scallop Flexopecten glaber were underwent in this study. Results show that food deprivation induces a diminution of the amounts of the EPA (C20:5n-3) and the DHA (C22:6n-3) as well as the n-3/n-6 ratio. Meanwhile, a selective retention, in terms of increase of percentage, of the AA (C20:4n-6) in unfed specimens ...
An algorithm is given for deciding existential formulas involving addition and the divisibility relation over the natural numbers. In this paper it will be shown that there is an algorithm for deciding formulas of the form k 0) 3x,.3x„6N A /,(*.,..., xn)\g¡(xx, ...,xtt) /-I in N (the natural numbers), where the / and g¡ are linear polynomials with integer coefficients. (a\b means "a divides b"....
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm Aporrectodea rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking. Each population has been showed by several clones at least; moreover the clones from different places have never been identical. The clones in the range of o...
Fast neutrons are useful for activation analysis of several light elements. For example, oxygen analyses are routinely made in our reactor laboratory and elsewhere by the 160(n, p)]6N reaction. The threshold for this reaction is over 10 MeV. Napier et al. ~) have described a device which was intended to convert thermal neutrons into 14 MeV neutrons by the reaction sequence 6Li(n, o~)3H ... 2H(3...
