Optimization of a chemical method for skinning of sardines (Sardina pilchardus) during canning processing

Signature of an early genetic bottleneck in a population of Moroccan sardines (Sardina pilchardus).

Fishery assessment models meant to determine sustainability of commercial marine fish failed to predict recent stock collapses due to overexploitation. One flaw of assessment models is that they strongly rely on catch and age-composition statistics, but largely ignore the genetic background of the studied populations. We examined population genetic structure of sardine (Sardina pilchardus) in t...

solution of security constrained unit commitment problem by a new multi-objective optimization method

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

Heavy metals (Zn, Cd, Cu, Pb, and Fe) assessment in sardines, Sardina pilchardus (Walbaum, 1792) from the Algerian west coast

The sardine (Sardina pilchardus) is the most popular species for fishing of the Algerian coast. Five toxic metals zinc (Zn), cadmium (Cd), copper (Cu), lead (Pb), and iron (Fe) that can affect human health are studied in this fish. Samples are collected monthly between January and December 2019 in the Ghazaouet bay. The collected samples were analyzed by atomic absorption spectrophotometry by s...

Optimisation of liquor yield during the hydraulic pressing of sardine (Sardina pilchardus) discards

Fresh sardine (employed as discard model species) was pressed with a hydraulic press in order to obtain a partially dewatered cake (whose volume represents between 55% and 60% of the initial volume of raw material) and a 3-phase press liquor comprising an aqueous fraction, an oil fraction and a variable amount of suspended solids. Pressing conditions, such as final pressure to which the sardine...
