Electrical Vehicles: To What Extent are Environmentally Friendly and Cost Effective? – Comparative Study by European Countries

Runoff from typical urban and suburban landscapes may contain significant levels of nitrogen, phosphorus, and a broad spectrum of various pesticides (mainly herbicides and insecticides) due to excessive application rates of these chemicals and high irrigation requirements of most commonly used landscape plant species. Preliminary water quality data (runoff) from a comparative study of 20 microwatersheds using 4 different levels of maintenance, show reductions in these types of pollutants in runoff for microwatersheds planted to resource efficient plants. Utilization of plants indigenous to an ecoregion (and other resource efficient plants) in landscape design and management allows considerable reduction in inputs from fertilizer, water, and pesticides. This results in lower pollutant concentrations in runoff and is estimated to result in lower total pollutant loadings from such systems. Installation of native or resource efficient plants in new developments (commercial and residential) and replacement of existing landscapes with these plants as older plants die or neighborhoods are updated could provide cities and suburban areas with a cost-effective, low-maintenance, and aesthetically-pleasing pollution control technology. Data from the comparative study should provide municipalities charged with meeting the new requirements of the National Pollutant Elimination Discharge System with a way to compare the pollution prevention effectiveness of resource-efficient landscapes with more traditional structural urban runoff controls.

Abstract Purpose The aim of this study was to describe the implementation and uptake of biosimilar trastuzumab in Denmark compared with other European countries. Methods European data for usage of trastuzumab was supplied by IQVIA™, using the MIDAS® dataset. A comparison was performed based on market share estimated in sales volume. A separate comparison was undertaken between countries with a full two-fold switch between different biosimilars. Data was collected spanning the time from first registered sales of biosimilar trastuzumab until the 1st quarter of 2020. Results Denmark had the fastest and most thorough uptake of biosimilar trastuzumab compared with other EU countries. After 3 months, the market share of biosimilar trastuzumab had increased to 90% while the second fastest country had a 50% market share after 3 months. Only two other countries had undergone a full second switch between biosimilars, Hungary and Norway. All of the three countries made near complete switches between biosimilars while only Denmark had reduced the use of biooriginator below 10%. Conclusion The implementation of biosimilar trastuzumab in Denmark was rapid and achieved high overall uptake compared with other EU countries. The switch from one biosimilar to another was also achieved quickly and thoroughly. We believe that the rapid dissemination of information and involvement of all stakeholders — administrators, pharmacies, prescribers, nurses, and patients — constitute the backbone of the Danish success. A similar strategy is recommend for biosimilar implementation in other countries.

Zinc Coatings

<p>Metallic zinc coatings are well established as cost-effective corrosion protection for steel bridges. The zinc coating acts first as barrier protection, isolating the base steel from corrosive elements, and secondly by cathodic protection, acting as a sacrificial anode to protect the steel should the coating be compromised. Bridge operators can be confronted by disproportional high maintenance costs for bridges in use as removal of (in)organic paint systems with hazardous and toxic compounds require expensive waste disposal and environmental protection measures. Metallic zinc coatings are recognized as environmentally friendly, sustainable, and low maintenance, providing the lowest life cycle cost corrosion protection. Various case studies with bridges protected with metallic zinc coatings in and outside Europe are illustrated.</p>

Care Surgery

INTRODUCTION:The recent trend in health care centres everywhere is to provide cost effective care to the patients. There is an increasing trend towards ambulatory day care surgery and rapid discharge of the patients. The operation of inguinal hernia or incisional hernia and even simple ligation surgeries are done without much complexities nowadays and can be completed in 60-90min without much intra or postoperative complications. Hence these have become an ideal procedure for outpatient setting and thereby reducing length of hospital stay. AIMS AND OBJECTIVE:A comparative study of efcacy, potency and recovery of intrathecal 0.5% ropivacaine with fentanyl and 0.5% levobupivacaine with fentanyl in lower abdominal surgeries in patients of 18-60years of age. MATERIALS AND METHOD: This is a prospective, comparative, observational study was conducted on 60 patients undergoing various lower abdominal surgeries under subarachnoid block (SAB) at Nil Ratan Sircar Medical College and Hospital, Kolkata, West Bengal. This study was conducted over a period of 24-month. Approval of the Institutional Ethics Committee was taken. Awritten informed consent in the local language was taken from every patient. RESULT AND ANALYSIS: In RF 5 patients (17%) had onset at 3min, 17patients (57%) at 6min, 7 patients (23%) at 9min, 1 patient (3%) at 12min. In LBF 8 patients had onset at 0 min, 22 patients had onset at 3min. p value is less than 0.0001 which is statistically signicant. In RF, 23 patients (77%) had duration of motor block for 150min and 7 patients (23%) had for 180min. In LBF, 26 patients (87%) had duration of motor block for 210 min and 4 patients (13%) had for 180min. The p value is less than 0.0001, which is statistically signicant. SUMMARYAND CONCLUSION: This study was to compare potency, efcacy and recovery between the two groups of drugs. A potency of a drug is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. Here both the drugs in comparison was given in equal concentration and found that levobupivacaine produced higher effect, reached Bromage 3 in lesser time than ropivacaine. So levobupivacaine was more potent drug. Efcacy is the ability to get a job done satisfactorily
