A uracil nitroso amine based colorimetric sensor for the detection of Cu²⁺ ions from aqueous environment and its practical applications

A simple uracil nitroso amine based colorimetric chemosensor (UNA-1) has been synthesized and screened for its cation recognition ability. Sensor UNA-1 exhibited a high sensitivity and selectivity towards Cu²⁺ ions in aqueous medium in the presence of a wide range of other competing cations (Ag⁺, Al³⁺, Ba²⁺+, Ca²⁺, Cd²⁺, Co²⁺, Cr³⁺, Cs⁺, Fe²⁺, Fe³⁺, Li⁺, Mg²⁺, Mn²⁺, Na⁺, Ni²⁺, Pb²⁺, Zn²⁺, Hg²⁺ and Sr²⁺). With Cu²⁺, the sensor UNA-1 gave a distinct color change from colorless to dark yellow by forming a complex of 1:1 stoichiometry. Furthermore, sensor UNA-1 was successfully utilized in the preparation of test strips and supported silica for the detection of Cu²⁺ ions from aqueous environment

Evaluation of the Antiasthmatic Activity of Methanolic Extract of Trigonella Foenum Graecum on Experimental Models of Bronchial Asthma

The present study deals with the phytochemical screening and evaluation of antiasthmatic activity of methanolic extract of Trigonella foenumgraecum on experimental models of bronchial asthma and anaphylaxis. The antiasthmatic activity was studied on histamine-induced bronchospasm in guinea pig (Dunkey-Hartley) for respiratory parameters such as maximum airflow, minimum airflow, tidal volume, respiratory rate, minute volume, specific airway resistance determination on double chambered whole body plethysmography on un-anesthetized guinea pigs, for mast cell degranulation by compound 48/80 (in vitro) was done using rat (Albino Wistar) peritoneal fluid. Trigonella foenum graecum treated result indicated significant protection against histamine-induced bronchospasm in guinea pigs at highest dose i.e. 400mg/kg. The bronchodilatory effect of Trigonella foenum graecum was found comparable to the protection offered by the standard drug Salbutamol on respiratory parameters in double chambered whole body plethysmography, Treatment with Trigonella foenum graecum at a dose of 400mg/kg showed a significant decrease in degranulation rate of actively and passively sensitized mast cells of sensitized rats when challenged with antigen. Trigonella foenum graecum. Possess significant anti-asthmatic activity due to its potential anti inflammatory, antioxidant and the antihistaminic activity, which reflects as anti-degranulating effect on mast cells and on respiratory parameters.

These are administered to various diseases such as dysentery, whitlow, throat infection, mouth ulcers, earache, impotency, fever, bone-fever, cough, migraine, stomach-ache, bone fracture, rheumatism, post-pregnancy complaints, etc., They are employed in the form of extract, infusion, paste, powder, juice, decoction, etc. The district is inhabited by tribes viz., Gond, Baiga, Koraku, Bhariaya, Halba, Bhil, Kaul and Pawara. The population of the region is predominantly rural and tribal having considerable knowledge about ambient plant wealth and their traditional utilities. The correct scientific name of plant, family and local names, preparations of medicinal recipes, dosage, mode of administration and diseases treated are given. These have been gathered from medicine-men, elders and experienced informants. This is attempt to evaluate the ethnomedicinal claims, which in turn on further scientific scrutiny, may emerge as new drugs. ÂÂ

Selective Flotation of Scheelite and Calcite

The gold tailings from Gold Fields containing low scheelite values has a compled mineralogy with hornblende, quartz, arsenopyrite and calcite as major gangue minerals. The most difficult problem in scheelite flotation is not the removal of the siliceous or sulphide gangue, but the separation of Scheelite and calcite minerals which have similar surface properties. This is greatly influenced by many factors(1)such as (1) the extent of adsorption of the collectors (2) the dissolution of the minerals and the interference by the released species and (3) the intera-ction of adsorbed ions with the mineral surface. Direct flotation tests to recover scheelite from tailings failed due to the dilution of the concentrate by calcite. Hence to adopt the flotation process successfully, it is nece-ssary to depress the calcite selectively which is not achi-eved easily(2) due to the presence of small amounts of Ca, Mg and Fe salts and the lean grade of the ores to be treated. Slime coating(3) is also another factor adver-sely affecting the flotation of scheelite. The present study is an attempt to improve the selectivity of separ-ation of scheelite, based on the flotation of pure clacite-scheelite system using sodium oleate as collector

Study of Residential Project to Find Various Difficulties Faced During Construction & Find Solutions for Cost & Time Optimization

Obstructions in construction projects is considered one of the most common problems causing a multitude of negative effects on the project and its participating parties. This paper aims to identify the main causes of Obstruction in construction projects in India from the point of view of contractors, consultants, and owners. A literature review was conducted to compile a list of Obstruction causes that was purged based on appropriateness to India in seven semi structured interviews. The resulting list of Obstruction causes was subjected to a questionnaire survey for quantitative confirmation and identification of the most important causes of Obstruction. The overall results indicated that the most important causes are: financing by contractor during construction, Obstructions in contractor�s payment by owner, design changes by owner or his agent during construction, partial payments during construction, and no utilization of professional construction/contractual management. This paper deal with all literature related to obstruction

Prescription pattern of antimicrobial agents prescribed in outpatient department of dermatology in a tertiary care hospital in India

Background: Skin diseases contribute largely to global disease burden. Antimicrobial agents are used for treatment of various skin diseases of microbial aetiology caused by fungi, bacteria, viruses and ectoparasites. The primary objective of this study was to study the prescription pattern of antimicrobial agents in dermatology, to provide insights into the disease patterns, profile of the drugs used and their rationality. Methods: Cross-sectional observational study was conducted in dermatology outpatient department of T. N. M. C. and B. Y. L. Nair Charitable Hospital, Mumbai for period of 6 months. 372 prescriptions containing an antimicrobial agent (AMA) were analysed. Demographic data, disease pattern, associated comorbidities and prescription details were recorded after taking written informed consent. Results: Fungal infections were the most common (48%) followed by bacterial infections (31%). The most encountered condition was dermatophytosis. Average number of AMA per prescription was 2.33±0.73. Percentage of AMA prescribed by generic name was 48%. Percentage of AMA prescribed from National list of essential medicines 2015 (NLEM) was 32.60%. 87.9% of AMA were prescribed as combination therapy and 12.10% were prescribed as monotherapy. The commonest prescribed drugs were antifungals followed by antibiotics. Topical creams were the commonest prescribed dosage form. Conclusions: The most common class of antimicrobial agents prescribed was antifungal agents. Prescribing combination of oral antimicrobials with topical antimicrobials was found to be high. This study provides a framework for continuous prescription audit of antimicrobials in an outpatient setting and thus can help in rational use of antimicrobials in dermatological prescribing

Application of Inventory Management in Construction Project

Trust is central to every transaction that demands contributions from the parties involved. The financial turmoil resulting from the credit crunch that has troubled the global financial markets is an illustrative example of how the absence of trust paralyzed the banking credit system. The Until only a few weeks ago, few, if any, appreciated the real significance of the money markets within the wider global financial crisis and the importance of trust in these markets. But the freezing of the market for medium-term funding reflects a total loss of trust between banks. This paralysis of lending from loss of confidence jeopardizes the flow of money to every family and every business in the country. Analogously, if parties in the construction supply chain do not trust each other, their skepticism may not completely paralyze the operation but will certainly create unnecessary enquiries and checking procedures, resulting in serious bottlenecks and inefficiency. Changes are common during the construction phase of a project
