Aquaponics a modern approach for integrated farming and wise utilization of components for sustainability of food security: A review

Aquaponics is the sustainable approaches of present day’s world for raising fish species along with vegetables in a symbiotic association for sustainable food production. People are facing food crisis not only because of the adverse environmental condition but also due to unbalance environment population ratio. That is the main reason why the entire world is more concerned about the production of more food for security and sustainability. Present day’s modern farming system mainly focus on the productivity increasing technology and in due course individual are utilizing more chemical compounds that result in the degradation of soil. It shows great impact on ecological environment. Most of the cultivable land is also turned out as a site of construction which reduces the cultivable land on earth and ultimately arising the food insecurity. In such a circumstance a new approach of aquaponics might be beneficial where water solely covers the two third of the total mass. Aquaponics is a soilless culture which gained immense popularity as it focuses on organic production of vegetables within a single recirculating aquaponics system. Along with the sustainability it also emphasis economic efficacy and enhancement of productivity.  It can be grown used on non-arable lands such as deserts, degraded soil or salty, sandy islands. So, it can integrate livelihood strategies to secure food and small incomes for landless and poor households

Реконструкция электрической части подстанции 35/10 кВ "Велута" и повышение надёжности фрагмента распределительной электрической сети

Background: Globally, at least 2.65 million stillbirths occur every year, of which more than half are during the antepartum period. The proportion of intrapartum stillbirths has substantially declined with improved obstetric care; however, the number of antepartum stillbirths has not decreased as greatly. Attempts to lower this number may be hampered by an incomplete understanding of the risk factors leading to the majority of antepartum stillbirths. We conducted this study in a tertiary hospital in Nepal to identify the specific risk factors that are associated with antepartum stillbirth in this setting. Methods: This case-control study was conducted between July 2012 and September 2013. All women who had antepartum stillbirths during this period were included as cases, while 20 % of all women delivering at the hospital were randomly selected and included as referents. Information on potential risk factors was taken from medical records and interviews with the women. Logistic regression analysis was completed to determine the association between those risk factors and antepartum stillbirth. Results: During the study period, 4567 women who delivered at the hospital were enrolled as referents, of which 62 had antepartum stillbirths and were re-categorized into the case population. In total, there were 307 antepartum stillbirths. An association was found between the following risk factors and antepartum stillbirth: increasing maternal age (aOR 1.0, 95 % CI 1.0-1.1), less than five years of maternal education (aOR 2.4, 95 % CI 1.7-3.2), increasing parity (aOR 1.2, 95 % CI 1.0-1.3), previous stillbirth (aOR 2.6, 95 % CI 1.6-4.4), no antenatal care attendance (aOR 4.2, 95 % CI 3.2-5.4), belonging to the poorest family (aOR 1.3, 95 % CI 1.0-1.8), antepartum hemorrhage (aOR 3.7, 95 % CI 2.4-5.7), maternal hypertensive disorder during pregnancy (aOR 2.1, 95 % CI 1.5-3.1), and small weight-for-gestational age babies (aOR 1.5, 95 % CI 1.2-2.0). Conclusion: Lack of antenatal care attendance, which had the strongest association with antepartum stillbirth, is a potentially modifiable risk factor, in that increasing the access to and availability of these services can be targeted. Antenatal care attendance provides an opportunity to screen for other potential risk factors for antepartum stillbirth, as well as to provide counseling to women, and thus, helps to ensure a successful pregnancy outcome

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely
