The earthwormPontoscolex corethrurus(Müller, 1857) is reported for the first time from Punjab, India. This species was first described by German naturalist Fritz Müller in 1857 from Santa Catarina state of Brazil. It is commonly found in gardens, cropland and fallowlands. It tolerates wide range of climatic and edaphic factors due to its endogeic ecological category.P. corethrurushas high efficiency for organic matter assimilation and has ability to live in new habitat due to which it can survive even in very poor soil. The life cycle of this species is well documented and this species has economic importance due to its use in waste management.

Single Factor Experiment

In the study, magnesium oxide (MgO) was used to catalyze peroxymonosulfate (PMS) for the degradation of organic pollutants for the first time. According to the single-factor experiment results, it was determined that MgO could efficiently catalyze PMS to degrade organic matters in a wide range of pH values. Based on radical quenching experiments and electron spinning resonance spectra, singlet oxygen was identified to be the crucial reactive species. Importantly, the oxygen vacancy on the surface of MgO was determined as the key active site, which accelerated the decomposition of PMS to produce singlet oxygen. This study provides an interesting insight into the novel and ignored catalyst of MgO for the highly efficient activation of PMS, which will greatly benefit the Fenton-like catalytic degradation of organic wastewater.

Glyphonix bimarginatus (Figure 1) is a common click beetle pest of various economically important crops. The larvae of click beetles (Coleoptera: Elateridae) are elongated, wire-like and commonly known as wireworms. Wireworms are considered as subterranean economic pests during their larval stages in many parts of the world including the United States. The larvae of Glyphonix bimarginatus are commonly found with larvae of other click beetles in the field. Larvae of Glyphonix bimarginatus occurs in soil rich in organic matter and rarely in sandy soil. Young roots and germinating seeds are commonly fed upon by the larvae. This document describes its distribution, life cycle and biology, hosts, economic importance, and management. Also available on the Featured Creatures website at http://entomology.ifas.ufl.edu/creatures. https://edis.ifas.ufl.edu/in1233

<p>The Netherlands is a densely-populated country, with many rivers and roads. As a result, there are many intersections between roads and waterways, and these intersections are heavily used. Movares is a Dutch engineering consultancy and we can draw on over 100 years’ experience with a wide range of bridges and viaducts. We are among the Netherlands’ leading consultants in the field of movable bridges. Our knowledge and experience put us in a perfect position to look after bridges from initial design through to end of service life.</p><p>Many Dutch bridges – both movable and fixed – were built in the 1950s and 1960s, and were not designed for today’s increased, heavier traffic. They are showing symptoms of fatigue and/or no longer conform (demonstrably) to current requirements. As a result, they need to be replaced. The availability of infrastructure is of great economic importance</p><p>At the same time, safety must be guaranteed. Our philosophy: “If it ain’t broke, don’t fix it!” Our ap-proach – the BridgeDoctor® – allows us to establish the condition of a bridge with the aid of a rapid analysis. In many cases, we can use smart measures to extend the life of a bridge, allowing it to remain in service for several more decades.</p><p>By an inventory based on available information. The aim is to gain insight into the status of the bridges now, but also in the future. On this basis it is possible to predict when the bridge needs to be replaced or, and of course, how and when to intervene constructively. This inventory provides quick answers to questions such as: which bridge is constructively safe and which bridge should be tackled first?</p><p>Maintenance also prevents emergency repairs and saves a lot of money (emergency repair = costly and timely maintenance can lead to less maintenance.</p>

Notwithstanding the undoubted economic importance of the Tabanidae, which is second only to that of the Culicidae among blood-sucking insects, our information concerning the habits and life-histories of Canadian species is very meagre indeed. What knowledge we possess has been chiefly derived from the studies made by entomologists of the United States, who have discussed among others some of the species that occur on both sides of the international boundary. Of the species dealt with in the present paper, Hart (1896, p. 227) observed oviposition by Chrysops moerens, Walk., in Illinois, and a description of the egg was given. This brief account was supplemented by Hine (1906, p. 36) in Ohio, who published a detailed description of the process of oviposition of the same species and was, moreover, successful in rearing Tabanus lasiophthalmus, Macq., from the egg to the adult—the first time that this had been accomplished for a Tabanid species. Jones & Bradley (1923, p. 310), working in Louisiana, discovered in the course of their investigations on the Tabanidae a single larva of T. reinwardtii, Wied., from which an adult was reared, but no description of the larva was offered. Webb & Wells (1924) published an account of the partial life-cycle of T. phaenops, O.S., including descriptions of the early stages, as well as of T. insuetus, O.S., in which all stages other than the egg were obtained and described.

Synthetic Sequence

Benzofurans are everywhere in nature and they have been extensively studied by medicinal chemists over the years because of their chemotherapeutic and physiological properties. Herein, we describe a strategy that can be used to access elaborate benzo-2-carboxamide derivatives, which involves a synthetic sequence of 8-aminoquinoline directed C–H arylations followed by transamidations. For the directed C–H arylations, Pd catalysis was used to install a wide range of aryl and heteroaryl substituents at the C3 position of the benzofuran scaffold in high efficiency. Directing group cleavage and further diversification of the C3-arylated benzofuran products were then achieved in a single synthetic operation through the utilization of a two-step transamidation protocol. By bocylating the 8-aminoquinoline amide moiety of these products, it proved possible to activate them towards aminolysis with different amine nucleophiles. Interestingly, this aminolysis reaction was found to proceed efficiently without the need of any additional catalyst or additive. Given the high efficiency and modularity of this synthetic strategy, it constitute a very attractive approach for generating structurally-diverse collections of benzofuran derivatives for small molecule screening.

The entry of a wide range of biotechnological products into the pharmaceutical market calls for rein-forcement of the quality, efficacy and safety standards at the state level. The following general monographs have been elaborated for the first time to be included into the State Pharmacopoeia of the Russian Federation, XIV edition: "Viral safety" and "Reduction of the risk of transmitting animal spongiform encephalopathy via medicinal products". These general monographs were elaborated taking into account the requirements of foreign pharmacopoeias and the WHO recommendations. The present paper summarises the key aspects of the monographs.

Drinking Water Production

Membrane fouling by natural organic matter (NOM), namely by humic substances (HS), is a major problem in water treatment for drinking water production using membrane processes. Membrane fouling is dependent on membrane morphology like pore size and on water characteristics namely NOM nature. This work addresses the evaluation of the efficiency of ultrafiltration (UF) and Coagulation/Flocculation/UF performance in terms of permeation fluxes and HS removal, of the water from Tagus River (Valada). The operation of coagulation with chitosan was evaluated as a pretreatment for minimization of membrane fouling. UF experiments were carried out in flat cells of 13.2×10−4 m2 of membrane surface area and at transmembrane pressures from 1 to 4 bar. Five cellulose acetate membranes were laboratory made to cover a wide range of molecular weight cut-off (MWCO): 2,300, 11,000, 28,000, 60,000 and 75,000 Da. Severe fouling is observed for the membranes with the highest cut-off. In the permeation experiments of raw water, coagulation prior to membrane filtration led to a significant improvement of the permeation performance of the membranes with the highest MWCO due to the particles and colloidal matter removal.
