Unicellular algae from the genus chlorella grown under various conditions : potential for use as feed

Diverse morphological and physiological characteristics of microalgae are enabling their use in the production of protein, vitamins, antioxidants, drugs, immunostimulants, biofuels and food supplements. These physiological characteristic was the main reason for intensive research on microalgae cells in recent years. Being singe celled gives them the opportunity to spread on the much wider surface maximizing use of sunlight contrary to plants that has limited surface and position. Their simple cell structure will ensure the rapid and successful growth of under various conditions. This characteristic enables them to be present in the most diverse ecosystems (sea, rivers, lakes, lagoons) and the habitats with unfavorable environmental conditions for other species. Algae can grow in places that are unsuited for agriculture, such as desert, wastelands or unfertile coastal areasM-H

Consequences of Compliance and Deterrence Models of Law Enforcement for the Exercise of Police Discretion

The Internet is suffering from ossification. There has been substantial research on improving current protocols, but the vendors are reluctant to deploy new ones. We believe that this is in part due to the difficulty of evaluating protocols under realistic conditions. Recent wide-area testbeds can help alleviate this problem, but they require substantial resources (equipment, bandwidth) from each participant, and they have difficulty in providing repeatability and full control over the experiments. Existing in-house networking testbeds are capable of running controlled, repeatable experiments, but are typically small-scale (due to various overheads), limited in features, or expensive. The premise of our work is that it is possible to leverage the recent increases in computational power to improve the researchers' ability to experiment with new protocols in lab settings. We propose a cost-effective testbed, called MX, which emulates many programmable routers running over a realistic topology on multi-core commodity servers. We leverage open source implementations of programmable routers, such as Click, and modify them to allow coexistence of multiple instances in the same kernel in an effort to reduce packet forwarding overheads. Our initial results show that we outperform similar cost-effective solutions by a factor of 2. Next, we demonstrate that grouping and placing routers on to cores which share the L2 cache yields high performance.QC 20140707</p

The new face of East-West migration in Europe

In order to contextualise the papers in this special issue, this paper presents an overview and framework for understanding the importance of East–West migration in Europe associated with the EU enlargement process. The new patterns and forms of migration seen among East European migrants in the West—in terms of circular and temporary free movement, informal labour market incorporation, cultures of migration, transnational networks, and other phenomena documented in the following papers—illustrate the emergence of a new migration system in Europe. Textbook narratives, in terms of standard accounts of immigration, integration and citizenship based on models of post-colonial, guestworker and asylum migration, will need to be rethought. One particularly fertile source for this is the large body of theory and research developed in the study of Mexican–US migration, itself a part of a regional integration process of comparative relevance to the new European context. While the benefits of open migration from the East will likely triumph over populist political hostility, it is a system that may encourage an exploitative dual labour market for Eastern movers working in the West, as well as encouraging a more effective racial or ethnically-based closure to immigrants from South of the Mediterranean and further afield

Plants as Bio-Insecticides in the Service of the Suppression of Potato Tuber Moth in Storage

Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is economically very important pest of potato and other solanaceous plants in the field and warehouse. Frequent and excessive use of insecticides leads to development of insects resistance, environmental pollution, and lives residues in food. All this implicated as a obligatory applications of botanical insecticides. Research in this area is increasingly attracting attention as the kingdom of plants is an inexhaustible source of active ingredients with insecticidal properties. This is the only way in the registration and appropriate use of eco-friendly active ingredients as pesticides

Impact of fluid balance and opioid-sparing anesthesia within enchanced recovery pathway on postoperative morbidity after transthoracic esophagectomy for cancer

BackgroundEnhanced Recovery After Surgery (ERAS) protocol for esophagectomy may reduce the high incidence of postoperative morbidity and mortality. The aim of this study was to assess the impact of properly conducted ERAS protocol with specific emphasis on fluid balance and opioid-sparing anesthesia (OSA) on postoperative major morbidity and mortality after esophagectomy.MethodsPatients undergoing elective esophagectomy for esophageal cancer at the Hospital for Digestive Surgery, University Clinical Center of Serbia, from December 2017 to March 2021, were included in this retrospective observational study. Patients were divided into two groups: the ERAS group (OSA, intraoperative goal-directed therapy, and postoperative “near-zero” fluid balance) and the control group (opioid-based anesthesia, maintenance mean blood pressure ≥ 65 mmHg, and liberal postoperative fluid management). The primary outcome was major morbidity within 30 days from surgery and 30-day and 90-day mortality. Multivariable analysis was used to examine the effect of the ERAS protocol.ResultsA total of 121 patients were divided into the ERAS group (69 patients) and the control group (52 patients). Patients in the ERAS group was received less fentanyl, median 300 (interquartile range (IQR), 200–1,550) mcg than in control group, median 1,100 (IQR, 650–1750) mcg, p &lt; 0.001. Median intraoperative total infusion was lower in the ERAS group, 2000 (IQR, 1000–3,750) mL compared to control group, 3,500 (IQR, 2000–5,500) mL, p &lt; 0.001. However, intraoperative norepinephrine infusion was more administered in the ERAS group (52.2% vs. 7.7%, p &lt; 0.001). On postoperative day 1, median cumulative fluid balance was 2,215 (IQR, −150-5880) mL in the ERAS group vs. 4692.5 (IQR, 1770–10,060) mL in the control group, p = 0.002. After the implementation of the ERAS protocol, major morbidity was less frequent in the ERAS group than in the control group (18.8% vs. 75%, p &lt; 0.001). There was no statistical significant difference in 30-day and 90-day mortality (p = 0.07 and p = 0.119, respectively). The probability of postoperative major morbidity and interstitial pulmonary edema were higher in control group (OR 5.637; CI95%:1.178–10.98; p = 0.030 and OR 5.955; CI95% 1.702–9.084; p &lt; 0.001, respectively).ConclusionA major morbidity and interstitial pulmonary edema after esophagectomy were decreased after the implementation of the ERAS protocol, without impact on overall mortality

Meat Analogues from Pea Protein: Effect of Different Oat Protein Concentrates and Post Treatment on Selected Technological Properties of High-Moisture Extrudates

The effect of using oat protein concentrates from different sources on the techno/functional properties of pea protein high-moisture extrudates (HME) have been investigated. The oat protein fractions were commercially produced by wet milling (OP) or produced by dry fractionation (OA) in our pilot plant facilities. The texture cutting force of HME was significantly increased by the inclusion of OP and had higher anisotropy, while addition of OA did not influence the texture. Addition of both oat sources to the pea mixture led to higher water and oil binding ability on both initial dry ingredients and extrudates. The color of the meat analogues was significantly affected by the type of oat added. CLSM image analysis of the extrudates showed that the type of oat used influenced fiber alignment and apparent porosity of the protein network. Post-extrusion treatment with water at 80 ◦C/20 min of the extrudates significantly reduced the cutting strength of the meat analogues and significantly caused a shift toward a lighter color. The reduction of texture strength of extrudates with OP rendered it similar to cooked chicken samples, while extrudates with OA showed a more resilient fiber strength to the hot water treatmentpublishedVersio
