Fluctuations and Movement Patterns of Race Chicken Egg Prices in Bengkulu Province

Chicken eggs are a staple food with a high enough animal protein content, but the price is quite affordable for all levels of society. This causes the consumption of chicken eggs to be relatively high compared to other animal protein sources, but currently, the amount of production and consumption by the public is not comparable; besides that, the price offered is constantly fluctuating. This study aims to determine price fluctuations and price movement patterns of broiler chicken eggs in Bengkulu Province. The data used is secondary data. The research method uses quantitative descriptive analysis. The research results show that. The risk of fluctuations in the price of broiler eggs in Bengkulu Province has a slightly higher risk for prices at the producer level when compared to prices at the consumer level. The development pattern of broiler egg prices in Bengkulu Province generally shows a positive direction. Fluctuations in the price of broiler eggs occur in specific periods. These fluctuations occur because they coincide with religious holidays such as Ramadan, Eid al-Fitr, Christmas and New Year, the influence of the Russia-Ukraine war, and economic problems due to the Covid-19 pandemic.Telur ayam merupakan salah satu makanan pokok yang memiliki kandungan protein hewani yang cukup tinggi namun harganya cukup terjangkau oleh semua lapisan masyarakat.

Des lacs collinaires pour un développement durable en Tunisie semi-aride

L'opération lac collinaire est une des composantes les plus importantes de la stratégie nationale et décennale 1990-2000 en matière de conservation des eaux et des sols en Tunisie. Les premiers résultats des observations d'un échantillon d'une cinquantaine d'ouvrages conduisent à la présentation d'une typologie fondée sur l'utilisation de la ressource hydrique qui est encore peu développée. L'accent est mis sur le rôle majeur que peuvent jouer ces aménagements dans la prise de conscience d'une protection de l'environnement et dans l'amorce d'un développement local beaucoup plus autonome et durable. Ce dernier nécessite toutefois de préciser davantage le rôle de chaque partenaire concerné par l'aménagement. (Résumé d'auteur

Are estimates of socioeconomic inequalities in chronic disease artefactually narrowed by self-reported measures of prevalence in low-income and middle-income countries? Findings from the WHO-SAGE survey

Background: The use of self-reported measures of chronic disease may substantially underestimate prevalence in low-income and middle-income country settings, especially in groups with lower socioeconomic status (SES). We sought to determine whether socioeconomic inequalities in the prevalence of non-communicable chronic diseases (NCDs) differ if estimated by using symptom-based or criterion-based measures compared with self-reported physician diagnoses. Methods: Using population-representative data sets of the WHO Study of Global Ageing and Adult Health (SAGE), 2007–2010 (n=42 464), we calculated wealth-related and education-related concentration indices of self-reported diagnoses and symptom-based measures of angina, hypertension, asthma/chronic lung disease, visual impairment and depression in three ‘low-income and lower middle-income countries’—China, Ghana and India—and three ‘upper-middle-income countries’—Mexico, Russia and South Africa. Results: SES gradients in NCD prevalence tended to be positive for self-reported diagnoses compared with symptom-based/criterion-based measures. In China, Ghana and India, SES gradients were positive for hypertension, angina, visual impairment and depression when using self-reported diagnoses, but were attenuated or became negative when using symptom-based/criterion-based measures. In Mexico, Russia and South Africa, this distinction was not observed consistently. For example, concentration index of self-reported versus symptom-based angina were: in China: 0.07 vs −0.11, Ghana: 0.04 vs −0.21, India: 0.02 vs −0.16, Mexico: 0.19 vs −0.22, Russia: −0.01 vs −0.02 and South Africa: 0.37 vs 0.02. Conclusions: Socioeconomic inequalities in NCD prevalence tend to be artefactually positive when using self-report compared with symptom-based or criterion-based diagnostic criteria, with greater bias occurring in low-income countries. Using standardised, symptom-based measures would provide more valid estimates of NCD inequalities

Biochemical composition of three Tunisian silverside (fish) populations caught in open sea, lagoon and island coasts

Fatty acid and amino acid profiles were determined in three silverside populations caught in Tunisian waters Atherina boyeri (open sea), Atherina lagunae (lagoon) and Atherina sp. (island coasts). Saturated fatty acids reached in total lipids 43.54%, 36.96% in marine and 33.64% in insular silverside and A. lagunae, in which eicosapentaenoic acid, docosahexaenoic acid and linoleic acid were the prominent fatty acids. The n-3/n-6 index showed a significant level indicating a tendency to accumulate n-3 fatty acids in A. boyeri and A. lagunae and n-6 fatty acids in Atherina sp. Total amino acid content ranged from 528 to 588 mg/g crude protein, in which, glutamic acid was the most abundant. Methionine had the lowest essential amino acid score in A. boyeri and Atherina sp. (0.73 and 0.71, respectively)while tryptophan had the lowest in A. lagunae (0.07)

Extraction and characterization of chitin and chitosan from crustacean by-products: Biological and physicochemical properties

Chitin has been extracted from two Tunisian crustacean species. The obtained chitin was transformed into the more useful soluble chitosan. These products were characterized by their biological activity as antimicrobial and antifungal properties. The tested bacterial strains were Escherichia coli American Type Cell Culture (ATCC) 25922, Pseudomonas aeruginosa ATCC 27950 and Staphylococcus aureus ATCC 25923. Four fungi strains were also tested Candida glabrata, Candida albicans, Candidaparapsilensis and Candida kreusei. Squilla chitosan showed a minimum inhibitory concentration (MIC) against the different fungi exceptionally for C. kreusei. Their antioxidant activity was investigated with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and inhibition of linoleic acid peroxidation. Parapenaeus longirostris Chitosan showed the highest radical scavenging properties. Chitin and chitosan produced were also characterized with Fourier Transform Infrared Spectroscopy (FTIR).Key words: Antibacterial, antifungal, antioxidant, chitin, chitosan, crustacean

Ability to fatten Tunisian lambs in Sheepfold

L’aptitude à l’engraissement des agneaux de races tunisienne en fonction des régimes alimentaires disponibles est une demande importante voire obligatoire pour nos éleveurs à nos jours afin de trouver une synergie entre le coût de production d’un kg de viande et le prix de vente. Pour cela, on a procédé à réaliser un essai de performances des agneaux de races différentes conduits en bergerie et recevant une ration alimentaire classique à base de foin d’avoine et d’aliment concentré dans la ferme pédagogique de l'École Supérieure d’Agriculture de Mateur. Les résultats obtenus étaient dans les normes en tenant compte de la ration et l’âge des agneaux. L’ingestion moyenne de la matière sèche de foin d’avoine était de 551 g /j/agneau, l’indice de consommation moyen a été de 6,34 Kg MS/Kg de gain de poids, le poids vifs des agneaux évolue d’un semaine à l’autre pour atteindre un poids final de 18,2 kg. Mots clés: Engraissement, race ovine, Tunisie, Indice de consommationThe ability to fatten lambs of Tunisian breeds according to the diets available is an important or even a compulsory demand of our breeders today in order to find a synergy between the cost of production of one kg of meat and the price of sale. For this, we carried out a performance test of lambs of different breeds in sheepfolds and receiving a classic food ration based on oat hay and feed concentrate in the educational farm of the Higher School of Agriculture of Mateur. The obtained results were within the standards taking into account the ration and the age of the lambs. The average dry matter intake of oat hay was 551 g / day / lamb, the average consumption index was 6.34 Kg DM / Kg of weight gain, the live weight of lambs increased weekly to reach a final weight of 18.2 kg.

Spatiotemporal chaos induces extreme events in an extended microcavity laser

Extreme events such as rogue wave in optics and fluids are often associated with the merging dynamics of coherent structures. We present experimental and numerical results on the physics of extreme events appearance in a spatially extended semiconductor microcavity laser with intracavity saturable absorber. This system can display deterministic irregular dynamics only thanks to spatial coupling through diffraction of light. We have identified parameter regions where extreme events are encountered and established the origin of this dynamics in the emergence of deterministic spatiotemporal chaos, through the correspondence between the proportion of extreme events and the dimension of the strange attractor
