DAIRY COWS TREATED WITH A FUNCTIONAL FEED (NAT3): INVESTIGATION ON PUFA’S TRANSFER IN MILK AND CHEESES
No full textIn a previous trial we have demonstrated the increased content of fatty acids CLA and DHA in milk following to the administration of a functional feed NATW3(WBC 2008, Budapest). This study is to demonstrate that lower quantity of NATW3 in feed (320 g/subj./day vs 600 g/subj./day) resolves in similar results: decrease in SFA and increase in PUFA, especially cis-9 18:1, CLA and DHA. Trend of metabolic parameters was confirmed, expecially for lipidic status.
The trial involved 116 high-producing dairy cows belonging to two livestocks fed with the same feed: grass family hay (especially oat hay), grass family hay silage (triticale and barley), and industrial feed. The difference concerned the way of administration of industrial feed, ad libitum and with automatic feeding system. Milk was utilized for cheesemaking.
Analysis of lipid fractions stressed variations in composition , especially pointed out the transfer of PUFA in different cheeses, making their composition more suitable for a more salutistic intake.
“Mozzarella": total lipids +0,96%, total proteins +1,22%, CLA (C18: 2) +118,67%, DHA (C22: 6) +27%, EPA (C20: 5) +60,00%, palmitoleic acid (C16: 1) +29,15%, decrease of stearic acid(C18: 0) --9,84%.
”Canestrato": total lipidis +0,46%, total proteins +0,66%, CLA (C18: 2) +160,42%, DHA (C22: 6) + 80,00%, EPA (C20: 5) +154,54%, palmitoleic acid (C16: 1) +39,00%, decrease of stearic acid (C18: 0) -12,73%.
”Caciocavallo": total lipids +2,48%, total proteins +0,33%, CLA (C18: 2) +58,28%, DHA (C22: 6) + 55,00%, EPA (C20: 5) +76,67%, palmitoleic acid (C16: 1) +40,12%, decrease of stearic acid (C18: 0) -11,92%
METABOLIC EFFECTS AND REPRODUCTIVE PERFORMANCES IN DAIRY COWS TREATED WITH A FUNCTIONAL FEED (NAT®W3)
No full textThe Authors investigated to correlate metabolic efficiency to reproductive performances by the administration of functional feed in high-producing dairy cattle. The trial want to study, also, the capability of laboratory diagnostic in evaluation and estimation of the reproductive capacities to select subjects to submit to reproductive praxis.
Functional feed contains vitamins E, A, D3, organic-selenium, polyinsaturated fatty acids (PUFA) and a prebiotic by fermented cereals. Effects of PUFA administered were particularly investigated in lipoprotein fractions composition, in blood. Optimal relationship among LDL-cholesterol, total cholesterol and progesteron was related to best reproductive performances: in this trial. Authors can confirm this on the basis of livestock performances. Study realized during the most worm period of the year when mean daily temperature go up to 30°C.
Metabolic parameters considered are linked to energetic, mineral and endocrine metabolisms. Determination were realized in blood-samples before, during, after the administration of NAT3. Bovines were fed with different addition of NAT3 (320-360 g/subj/die) for 4 months.
Reproductive indices studied were: open-days and number of services per conception.
Trend analysis of fertility indices demonstrated that blood levels of progesterone and blood antioxidant capability are strictly correlated and correlated also to reproductive performances.
Efficacy of treatment is demonstrated by the trend of the fertility indices in the post treatment period during which indices return progressively to the pre treatment values in about 60 days: this period correspond to the lipid tissue turnover time. During these days a temporary build-up of PUFA and liposoluble vitamins was observed.
Blood progesterone levels were higher (2.2 times) in correspondence of the 21st day post partum in treated subjects respect to control ( 0.18 vs 0.44 ng/l). Reproductive indexes recorded stressed that open-days varied from to . Number of services per conception was reduced from 121 to 95 at 60th day of treatment. In the next four months the value of the index settled between 90-95 days.
Data obtained in this study show that administration of PUFA, antioxidants and probiotics administred in dairy cows can remodel metabolisms correlated to fertility such as progesterone, prostaglandins and prostacyclins synthesis. These evidences are stressed by trends recorded in the herd concerning values of open-days and the number of services per conception
Quality of life and anorectal malformations: a single-center experience
No full textPurpose: The treatment and long term clinical outcomes of anorectal malformations (ARM) in children have always been the focus of pediatric surgeons. This study aimed at reporting our experience as far as long-term follow-up of ARM in children is concern. Methods: We enrolled patients treated between 1999 and 2019, and established selection criteria to choose appropriate subjects. A validated questionnaire was used to determine long-term quality of life outcomes. Results: Out of a total of 48 patients treated within the study period, 28 were enrolled in this study. Among the latter, more than 35% had at least one long-time complication, and more than 90% had a good lifestyle. Urinary and fecal continence was achieved in more than 95% of the patients using medical devices. Conclusion: This study aimed to bring up new concepts; taking into consideration all aspects of life in patients with ARM, from school life to sexuality, while evaluating fecal and urinary continence. This is essential for the improvement of the skills of the different specialists involved in the management of these patients, and for the implementation of strategies that can improve postoperative function. Most especially, it will also help improve communication between doctors to ensure an adequate transition of these children into adult life

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe

No full textG-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
