Stabilisation of experimental bioretention basins during intermittent wetting and drying
Stormwater bioretention basins are subjected to spontaneous intermittent wetting and drying, unlike water treatment filter systems that are subjected to continuous feed. Drinking water filters when constructed new or after back-wash, are subjected to a phase of stabilization. Experiments show that bioretention basins are similarly impacted by intermittent wetting and drying. The common parameter monitored in the stabilisation of filters is the concentration of total solids in the outflow. Filter media in bioretention basins however, consists of a mix of particulate organic matter and fine sand. Organic carbon and solids are therefore needed to be monitored. Four Perspex bioretention filter columns of 94 mm (ID) were packed with a filter layer (800 mm), transition layer and a gravel layer and operated with synthetic stormwater in the laboratory. The filter layer contained 8% organic material by weight. A free board of 350 mm provided detention storage and head to facilitate infiltration. Synthetic stormwater was prepared by adding NH4NO3 (ammonium nitrate) and C2H5NO2 (glycine) and a mixture of kaolinite and montmorillonite clay, to tapwater. The columns were fed with synthetic stormwater with different Antecedent Dry Days (ADD) (0 â 25 day) and constant inflow concentration (2 ppm: nitrate-nitrogen, 1.5 ppm: ammonium-nitrogen, 2.5 ppm: organic-nitrogen 100 ppm: total suspended solids and 7 ppm: organic carbon) at a feed rate of 100mL.min (85.7cm/h). Samples were collected from the outflow at different time intervals between 2 â 150 min from the start of outflow and were tested for Total Suspended Solids (TSS) and Total Organic Carbon (TOC). Both TSS and TOC concentrations in the outflow were observed to be much higher than the concentration of both the parameters in the inflow during the stabilisation period indicating a phase of wash-off (first flush) which lasted for approximately 30 min for both parameters at the beginning of each storm event. The wash-off of TSS and TOC were found to be highly variable depending on the age of the filter and the number of antecedent dry days. The duration of stabilisation phase in the experiments is significant compared with many of the stormwater events. A computational analysis on total mass of each pollutant further affirmed the significance of the first flush of an event on removal of these pollutants. Therefore, the kinetics of the first flush in the stabilisation phase needs to be considered in the performance analysis of the systems
Neuroprotective Effect of Hydroalcoholic Extract of Boerhaavia Diffusa Linn against MPTP Induced Neurodegenartion in Rats
The present study was undertaken to find out the potential activity of Boerhaavia diffusa
against breast cancer and their effects on MPTP induced breast Neurodegenaration in rats.
From time immemorial mankind's efforts and ultimate aim have been to seek eternal
happiness. And his endeavour has been to overcome and seek appropriate remedies for things
that stand in his way. Plants have played a weighty role in maintaining human health and
improving the quality of human life for thousands of years and have several precious
components of medicines, seasonings, beverages, cosmetics, and dyes. Herbal medicines are
based on the premise that plants contain natural substance that can promote health and alleviate
illness. In recent times focus on plant research has increased all over the world and large
evidence has collected to show immense potential of medicinal plants used in various traditional
systems.
Today we are witnessing a great deal of public interest in the use of herbal remedies.
Many western drugs had their origin in plant extract. There are many herbs, which are
preponderantly used to treat cardiovascular problems, liver disorder, central nervous system,
digestive system, metabolic disorders and for Neuroprotective effects. Given their potential to
generate significant therapeutic effect, they can be useful as drug or supplement in the treatment
in the management of many diseases. Herbal drug or medicinal plants, their extract and isolated
compounds have demonstrated spectrum of biological activities. Such have been used and
continued to be used as medicine in folk-fore or food supplement for various disorders.
Boerhaavia diffusa (Punarnava) is one of the most famous medicinal plants in the
treatment of a large number of human ailments is mentioned in Ayurveda, Charaka Samhita, and
Sushrita Samhita. This work explains the evidence-based information regarding the
pharmacological activity of this plant. It has many ethnobotanical uses (the leaves are used as
vegetable; the root juice is used to cure asthma, urinary disorders, leukorrhea, rheumatism, and
encephalitis). The Boerhaavia diffusa plant contains a large number of such compounds as
flavonoids, alkaloids, steroids, triterpenoids, lipids, lignins, carbohydrates, proteins, and glycoproteins. Punarnavine, boeravinone, hypoxanthine 9-L-arabinofuranoside, ursolic acid,
punarnavoside etc.
Now this investigation was undertaken to study the effect of Boerhaavia diffusa on
MPTP induced Neurodegenaration and also planned to study the changes occuring in the
enzymic and non enzymic system such as super oxide dismutase, catalyase, glutathione peroxide
and lipid peroxidation level present in the living body. CONCLUSION:In summary, findings of the present study provide evidence that HAEBD at the dose
of 400mg/kg p.o alleviates behavioral deficits. It also reduced the oxidative parameter and
enhances the brain antioxidants, significantly prevents the brain from neurotoxic effects.
Therefore, Hydroalcoholic extract of Boerhaavia diffusa Linn contains flavanoids and
polyphenols was considered as powerful neuroprotective agent could offer a useful support to the

A clinico pathological study and management of necrotizing fasciitis cases in CMCH.
Necrotizing fasciitis is an infection occurring in the deep fascial layers. It is
a progressive infection. The diagnosis of necrotizing fasciitis is usually clinical and
is important to find it early as it is a fast spreading infection. Necrotizing fasciitis
occurs as a result of necrosis of skin and subcutaneous layer. NECROTIZING
FASCIITIS more frequent in elderly age group >50 years of age ,but it can occur
in almost all age group including children ,and healthy adult can also get affected.
NECROTIZING FASCITIS is most commonly seen in the elderly males.
source of the infection is identifiable in most of the cases. diabetic mellitus is the
most common comorbid factor . The disease is most commonly polymicrobical.
Most common bacterial includes gram positive cocci ( streptococci and
staphylococcal species ). Gram negative (E.coli, actinobacter, pseudomonas ).
Most common anaerobes is bacteroides
A Novel Mining Approach for Automatic Disease Detection in Sugarcane Plant Using Thresholding Method
Disease infection of agricultural products affects the agriculturists and human health and also degrades the quality and quantity of products. The tradition approach for detecting a disease is time consuming and very costly. The plant diseases are detected by automatic detection techniques that reduce a large work of continuous monitoring and observation in big farms by farmers or experts. The proposed algorithms detect the variety of diseases infected in sugarcane plants. The images are captured by digital camera. The noises in digital image are removed by low pass filter. This paper presents image segmentation using thresholding method which is used for automatic disease detection of sugarcane plants. SIFT method is applied for detecting and describing the local features of the plant species. The features such as colors, size shape and texture of surface is extracted by using GLCM feature extractor. The abnormal images are classified by using SVM classifier. In sugarcane plant, the diseases are detected automatically and yields 99% accuracy rate than existing techniques
A Population-Based Examination of Benzodiazepine Receptor Agonist & Z-drug Dispensations in the Alberta Population: Prevalence of Use and Indicators of Potentially Inappropriate Use and Prescribing
Introduction
Canadian clinical practice guidelines for the management of anxiety disorders and insomnia suggest that benzodiazepine receptor agonist and Z-drug (BZRA) treatment is appropriate for short term use in adults (aged 20-64); use of BZRAâs outside of these recommendations is considered âpotentially inappropriateâ given the increased potential for adverse effects.
Objectives and Approach
The objective of this study was to characterize the use of BZRAâs for all individuals 10 years of age or older in the province of Alberta in 2015 and to explore indicators of potentially inappropriate prescribing and use. Using data from Albertaâs Pharmaceutical Information Network (PIN) as well as Vital Statistics, prevalence of BZRA use was determined as were characteristics of BZRA dispensations according to prescriber type, days supply and number of defined daily doses. Patient-level indicators of potentially inappropriate BZRA prescribing or use (days of consecutive use, use of multiple ingredients etc.) were calculated by age category and sex.
Results
Overall, 372,870 individuals received 2,463,585 BZRA dispensations in 2015 (10% of Alberta population). The majority of users were female (63%), 28% were 65 years of age or older and 20% of individuals were dispensed both z-drugs and benzodiazepines. BZRA users received a median of 3 dispensations (IQR: 1-6), for a total of 91 days (IQR: 30-261) of use in the year, with a median period of consecutive use around 51 days (IQR: 21-128). 26\% of individuals utilized these medications for 121 consecutive days or more increasing to 40% in those 65 + years of age. 17% of individuals utilized more than one distinct BZRA ingredient concurrently while those in the 20-49 year age group were most likely to visit multiple prescribers.
Conclusion/Implications
Prevalence of BZRA use in Alberta is high, especially among females and the elderly. This study supports the need for patient and physician education, decision support for prescribers and continued monitoring of medication dispensing at the population level within the province of Albert

A multicentre, randomised controlled trial to compare the clinical and cost-effectiveness of Lee Silverman Voice Treatment versus standard NHS Speech and Language Therapy versus control in Parkinsonâs disease: a study protocol for a randomised controlled trial
Abstract: Background: Parkinsonâs disease (PD) affects approximately 145,519 people in the UK. Speech impairments are common with a reported prevalence of 68%, which increase physical and mental demands during conversation, reliance on family and/or carers, and the likelihood of social withdrawal reducing quality of life. In the UK, two approaches to Speech and Language Therapy (SLT) intervention are commonly available: National Health Service (NHS) SLT or Lee Silverman Voice Treatment (LSVT LOUDÂź). NHS SLT is tailored to the individualsâ needs per local practice typically consisting of six to eight weekly sessions; LSVT LOUDÂź comprises 16 sessions of individual treatment with home-based practice over 4 weeks. The evidence-base for their effectiveness is inconclusive. Methods/design: PD COMM is a phase III, multicentre, three-arm, unblinded, randomised controlled trial. Five hundred and forty-six people with idiopathic PD, reporting speech or voice problems will be enrolled. We will exclude those with a diagnosis of dementia, laryngeal pathology or those who have received SLT for speech problems in the previous 2 years. Following informed consent and completion of baseline assessments, participants will be randomised in a 1:1:1 ratio to no-intervention control, NHS SLT or LSVT LOUDÂź via a central computer-generated programme, using a minimisation procedure with a random element, to ensure allocation concealment. Participants randomised to the intervention groups will start treatment within 4 (NHS SLT) or 7 (LSVT LOUDÂź) weeks of randomisation. Primary outcome: Voice Handicap Index (VHI) total score at 3 months. Secondary outcomes include: VHI subscales, Parkinsonâs Disease Questionnaire-39; Questionnaire on Acquired Speech Disorders; EuroQol-5D-5 L; ICECAP-O; resource utilisation; adverse events and carer quality of life. Mixed-methods process and health economic evaluations will take place alongside the trial. Assessments will be completed before randomisation and at 3, 6 and 12 months after randomisation. The trial started in December 2015 and will run for 77 months. Recruitment will take place in approximately 42 sites around the UK. Discussion: The trial will test the hypothesis that SLT is effective for the treatment of speech or voice problems in people with PD compared to no SLT. It will further test whether NHS SLT or LSVT LOUDÂź provide greater benefit and determine the cost-effectiveness of both interventions.

Dynamics of nitrate-nitrogen removal in experimental stormwater biofilters under intermittent wetting and drying
High concentrations of nitrate-nitrogen degrade the quality of aquatic environments. The primary mechanism by which nitrate-nitrogen is removed (denitrification) requires anoxic conditions and electron donors. While removal of total and ammonium-nitrogen is often high in stormwater biofilters, poor removal or even the release of nitrate-nitrogen in the outflow has often been observed. Five Perspex biofilter columns (94 mm internal diameter) were fabricated with a filter layer that contained 8% organic material. Columns were operated at 875ââmm/h 875ââmm/h and fed with simulated stormwater with different antecedent dry days (ADDs) and concentrations of nitrate-nitrogen. Samples were collected from the outflow at different time intervals between 2 and 150 min and were tested for nitrate-nitrogen. The removal of nitrate-nitrogen varied during an event from a high removal percentage (60â90%) in the initial outflow that gradually decreased in the first 30 min and settled at 0â15% removal thereafter. This remained consistent during all simulated events independent of the number of ADDs or inflow concentrations. ADDs and previous event feed concentrations affected the outflow nitrate-nitrogen concentration in the first 30 min of the current event. Therefore, from this study it is concluded that denitrification within stormwater biofilters occurs mainly during drying periods rather than wetting periods
