Effect of Sludge and MKP Fertilizer Doses on Radish Plant Growth and Yield on Peatsoils. The development of the horseraean plant in peat land is faced with the number of obstacles in low, low ph, inlet, high c-organics with varying degrees of maturity and low - base base soils that are causing the growth and development of plants to be stunted, That would make a sludge delivery out of MKP fertilizer. The study is aimed at seeing the effect that doses of sludge given and MKP fertilizers have on the growth and growth of turnip plants in the peat soil. The research was conducted on KEP’S Agroland at Jl. Sui Raya Dalam, Pontianak City from March 12th to April 31th 2021. The study uses field experimental methods with comprehensive design prosecutions consisting of 2 treatment factors. The first factor is the sludge with the levels of treatment and the second factor is MKP fertilizer. Each factor is repeated 3 times, each denteronomy consisting of 4 plant samples, making the total number of plants 108. The first factor is the dose of sludge and the second is the dose of MKP fertilizer which has three levels of treatment each. Every treatment is repeated three times. A sludge dose consists of 0, 200, 320 g/polybag (equivalent to 0, 25, 40 tons /ha), while the MKP dosage consists of 0, 2, 4 g/polybag (equivalent to 0, 150, 250 kg/ha). The observed variabel is that of the number of leaves, the fresh weight of the plant, the fresh weight of the bulbous, the length of the tuber diameter and the plant’s dry weight. The research suggests and that there is no interaction between her and MKP for all variables. The treatment of sludge and MKP involving a dose of sludge 25 tons/hectares is equivalent to 200 g/polybag and MKP 150 kg/hectares is equivalent to 2 g/polybag is an efficient gift.

Currently, one of the most important problems in the world is waste bottles made of polyethylene terephthalate, the number of which is currently growing every hour, polluting the environment. One of the ways to protect the environment from polyethylene terephthalate waste is the invention of biodegradable polymer materials from PET waste. Currently, several methods for processing polyethylene terephthalate waste have been proposed, but the work on the production of biodegradable materials has not been fully solved. Currently, various technologies for recycling plastic bottles and bags are being developed. The most promising technology in this direction is chemical processing, which is based on obtaining the final product in the form of a monomer or oligomer, which can be used as a new raw material for the synthesis of polymers. In this work, these polyethylene terephthalate wastes were chemically degraded with ethylene glycol solvent in the presence of zinc acetate catalyst and bis-hydroxy ethylene terephthalate was obtained. This work aims to obtain bis-2-hydroxyethyl terephthalate (BHET) by glycolysis of polyethylene terephthalate (PET) waste for the synthesis of various types of biodegradable polymer films. Biodegradable films based on polyvinyl alcohol and BHET have been synthesized. Water-soluble copolymers based on BHET and PVA were obtained by grafted copolymerization. (PVA) polyvinyl alcohol (5; 15; 25 wt. %) was dissolved in distilled water at 75-80°C until complete dissolution, ammonium persulfate, used as an initiator, was added to the initial mixture and biodegradable films based on PVA and BHET were obtained for the first time. It has also been proved that the resulting biodegradable films are formed by hydrogen bonds using IR spectroscopy.

Chemotherapeutic agents are substances that cure infectious diseases for many years. However, problems arose due to drug resistance that developed over time and it was observed that the drugs failed to kill the bacteria. Studies have been carried out to find the factor caused by drug resistance that adversely affect the disease treatment, and these studies continue today. There are different types of resistance mechanisms. Efflux pumps are just one of these mechanisms. Efflux pumps cannot enter and release the drug into the cell. Thus, the microorganism becomes resistant to the drug used. If this resistance is inhibited, the drug may work. A variety of chemical or natural inhibitors are available for inhibition. However, since they cause toxicity problems, their clinical use is not currently available. Studies in this area are ongoing. There are studies to determine the activity of the efflux pump. The activity of this mechanism can be detected with ethidium bromide (EtBr). In this study, it was aimed to determine the efflux pump activity of some resistant clinically isolated strains using EtBr dye. The strains that are Acinetobacter baumannii, Candida albicans, Candida glabrata, Candida tropicalis, Klebsiella pneumoniae, Providencia rustigianii, Serratia odorifera, Shigella flexneri, Staphylococcus aureus and Streptococcus pneumoniae microorganisms. Cartwheel method was applied on agars containing TSB with EtBr with different concentrations (0.0 mg/L, 0.5 mg/L, 1.0 mg/L, 1.5 mg/L, 2.0 mg/L and 2.5 mg/L). After the incubation, activation case was observed under UV light. It is concluded that each strain used has efflux pump activity. EtBr was released at 0.5 mg/L and did not fluoresce. Different fluorescence were observed under EtBr UV between 1.0 mg/L and 2.5 mg /L.

Modeling of variability of hydrological characteristics of the Tuzla group of lagoons under various variants of their water exchange with the sea
Authors: Tuchkovenko Yu. S. , Kushnir D. V. 
Published: July 2022

The article is devoted to solving the problem of stabilization of hydrological regime and hydro-ecological conditions of the Tuzla group of lagoons located in the central part of the Danube-Dniester interfluve by ensuring and regulating their water exchange with the open sea through artificially created channels in the barrier beach that separates the water body from the sea.
The research presents the results of adaptation of the well-known modern numerical hydrodynamic model Delft3D Flow Flexible Mesh to the conditions of the Tuzla group of lagoons, as well as the results of its application to determine the effectiveness of various variants for ensuring water exchange with the sea based on the outcomes of scenario mathematical modeling.
In particular, the following variants of channels functioning were studied: (1) a relatively narrow connecting channel at the 2nd km of the barrier beach (near the Burnas Lagoon) together with a wide and deep outlet that existed before 2015 at the 24th km of the barrier beach (near the Shagany Lagoon); (2) a wide controllable connecting channel in the Shagany Lagoon placed on the outlet, alongside with the above-mentioned channel in the Burnas Lagoon; (3) an additional (third) narrow channel at the strip of the barrier beach near the Alibey Lagoon.
The characteristics of the annual cycle of water salinity spatio-temporal variability were used as indicators of the effectiveness of management decisions for ensuring the stability of the lagoons' hydro-ecological conditions.
Based on the analysis of the scenario modeling results it was concluded that the optimum solution of the problem related to stabilizing the hydro-ecological regime of the water body consists in ensuring the constant multidirectional water exchange with the sea through two artificial connecting channels in the barrier beach (both with bottom marks of minus 1.0 m (Baltic Height System) and 60 m and 15 m wide for the Shagany Lagoon and the Burnas Lagoon respectively) throughout the year. This will deny any salinization of the water body over the long term.
For the specified variant the time of complete water renewal with sea water for the main lagoons of the Tuzla group would constitute 8 and 12 months for the Shagany Lagoon and the Alibey/Burnas Lagoons respectively.

Published: July 2022

BACKGROUND: During the COVID-19 pandemic, the Hillingdon Hospitals NHS Foundation Trust produced trust guidelines for the initial blood investigation of COVID-19 inpatients. However, insufficient education meant inconsistent adherence to this guidance. OBJECTIVE: To examine whether the implementation of a COVID-19 blood request panel improves adherence to local trust guidelines. METHOD: Between March and April 2020, initial blood investigations performed for positive COVID-19 cases were compared to guidelines. Results were presented locally and a COVID-19 panel was added to the electronic system that provided prompts for appropriate investigations. A re-audit between May and June 2020 was conducted to assess adherence post-intervention. RESULTS: 383 patients were identified in the initial audit cohort and a sample of 20 patients were re-audited. Adherence to Full Blood Count, Urea and Electrolytes, C-reactive Protein and Liver Function Tests increased to 100% from 99.7% ( p = 0.8), 99.2% ( p = 0.69), 98.7% ( p = 0.61), and 96.6% ( p = 0.4) respectively. Coagulation screen adherence increased to 90% from 72.8% ( p = 0.09). Appropriate requesting of D dimers increased to 50% from 19.9% ( p = 0.001). Inappropriate troponin requesting decreased to 26.3% from 38.9% ( p = 0.23). CONCLUSION: A user-friendly COVID-19 panel of investigations resulted in improved adherence to guidelines. Clear communication and education are essential to help alleviate uncertainty during a pandemic.
