The sixth harmonic (6ω, 133 nm) of a Ti:sapphire laser is generated using cascaded four-wave mixing in filamentation propagation of the fundamental (ω) and the second harmonic (2ω) pulses through Ne gas. The method provides the 6ω pulse energy higher than 5 nJ/pulse at 1 kHz and a pulse duration shorter than 17 fs without dispersion compensation.

Seasonal differences in the lipid contents and fatty acid composition of European Eels (Anguilla anguilla, Linnaeus 1758) caught from Orontes River (Hatay, Turkey) were determined. High levels, as well ω-3 ω-6 acids, are important factors product quality. High-content values eels differed between seasons (p<0.05). The compositions ranged 5.91-8.03 g/100 g saturated acids (SFA), 10.59-14.08 m...

The effect of fasting on spawning performance, maternal, and egg nutrient composition, embryo/larval development was monitored in gilthead seabream (Sparus aurata). Two broodstocks were fasted during two consecutive years, for a period 43 54 days within the season, preliminary (year 1, 5-year-old breeders) main study 2, 6-year-old breeders), respectively. Mean daily fecundity showed declining t...

the ratio of ω-6: ω-3 is connected to the higher risk of non-communicable diseases, thus this ratio is becoming more important than quantity of ω-6 and ω-3 in human nutrition. in countries like iran, cow’s milk is mainly produced in rural area and less in conventional systems. the lactating cows reared in rural and conventional farms are different in terms of nutrition, daily yields, and propor...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

A graph is even-hole-free if it has no induced even cycles of length 4 or more. A cap is a cycle of length at least 5 with exactly one chord and that chord creates a triangle with the cycle. In this paper, we consider (cap, even hole)-free graphs, and more generally, (cap, 4-hole)-free odd-signable graphs. We give an explicit construction of these graphs. We prove that every such graph G has a ...

The aims of this study were to determine the feeding effect of diets containing different ratio of ω-3 and ω-6 fatty acids and organic Zn on egg production and quality of Magelang duck. A total of 90 ducks of 20 weeks old were randomly divided into 18 experimental units by assigning a completely randomized design with 6 treatments and 3 replications. There were 6 dietary treatments, namely 1) r...

background: endometriosis is a common chronic inflammation which leads to infertility and chronic pelvic pain in affected women. secretory phospholipase a2 type iia (spla2iia) is an acute phase reactant that is markedly increased in inflammatory disorders. objective: to assess the effects of ω-3 and ω-6 polyunsaturated fatty acids (pufas) administration in endometrial cells culture on spla2iia ...
