The current research work presents laboratory experimental results on local scour around vertical-wall bridge abutments in uniform sediments under clear water scour conditions. The study reports an extensive experimental investigation, that was performed in an experimental model in the Technological Educational Institute of Thessaly, whose findings are used to describe the effects of various parameters on local scour depth evolution. The experimental measurements of scouring depths were obtained in the vicinity of the construction for different inflow discharges and flow duration. The expected bed erosion and the maximum scour depth at the upstream edge of the construction are satisfactorily simulated by the experimental procedure. Three different sizes of the abutment width normal to the flow direction were used in order to investigate the impact of this parameter to local scour variation.

All experimental test case results described in this work are relevant to unsteady, two-dimensional, quasi or fully three-dimensional flow calculations for viscous flows in open channels with sediment transport. All the experimental results are graphically presented and may be used to assist in the development of new and the verification and refinement of existing river numerical simulation models for computing free-surface flows with movable beds, specifically around bridge abutments and generally on bed level variation due to sediment transport.

Various disturbances of visual space recognition include unilateral spatial neglect (USN) and visual field defects (VFD) has been strongly associated with an increased risk for injury and with poor functional outcome. To quantitatively evaluate visual-spatial recognition in cerebrovascular disease patients, we developed a new measurement system able to present a versatile visual information. The system uses a head-mounted display (HMD) as the device that presents visual information. The purpose of this study was the development of a method for presenting diverse visual information and assessing visual space recognition using a new head mounted display (HMD) system. A total of eight subjects participated in this study, comprising four with USN and four with VFD. A test sheet was placed on a desk, and its image was projected on the display of the HMD. Then, space recognition assessment was conducted using a cancellation test and motion analysis of the eye, head and trunk movements under four conditions with images reduced in size and shifted. Leftward visual search was dominant in VFD patients, while rightward visual search was dominant in USN patients. The angular velocity of leftward eye movement during visual search of the right sheet decreased in both patient types. Motion analysis revealed a tendency of VFD patients to rotate the head in the affected direction under the left reduction condition, whereas USN patients rotated it in the opposite direction of the neglect. A new HMD system was developed for presenting diverse visual information and assessing visual space recognition which identified the differences in the disturbance of visual space recognition of VFD and USN patients were indicated. The HMD system may be available and effective for evaluating and training visual recognition and ADLs in VFD and USN patients as a clinical device.

A pretreatment facility was established at the canning factory of EKO cPlc. in Nyíregyháza, Hungary between 2012 and 2013 for treating the highly concentrated industrial waste water generated during the processing of sweet corn. This is one of the largest canning factories in Hungary. The results and technologies used for the pretreatment of waste water generated during the main production seasons of the past 3 years are summarized, with special emphasis on CODCr and BOD5 parameters. The mass of industrial waste water was generally around 1200 m3/d or 50 m3/h generated evenly in the course of 3 shifts per day. The mechanical pretreatment phase consists of the following steps: fine screen, trommel screen, grit tank. The biological unit, developed by a Hungarian team, consists of multiphase, aerobic, submerged contact media units. The biological phase is distributed under the FLEXIPAK®-MIX brand name, while the submerged biofilm contact media unit under the TURBOPAK® brand name and both are manufactured in Hungary. These biofilm systems are collectively called System Gyulavári. The systems and models have been and still are being installed in many different structures. In the case of the EKO canning factory the concentration of raw waste water reached a maximum of as high as 13.000 mg/l CODCr and 6000-6500 mg/l BOD5 values at times. The mandatory treatment values specified for public sewer systems are: 1000 mg/l CODCr and 500 mg/l BOD5. The diameter of the FLEXIPAK®-MIX system, namely the circular steel structure, built in a ringed format, is 28 meters in total. A total of 680 m3 in-line TURBOPAK® contact-media had been built into these 2 rings marked as I. and II. forming a total of 102.000 m2 biofilm surface.

In the center of the structure a 9.0 m Ø DUALOX (System Gyulavári) ventilation unit has been installed in cells a, b, c and d joined in-line. Circular flow and supplementary O2 supply is ensured by 20 HP-Jet injector pumps which are suspended at 4 different locations resulting in 250-300 instances of contact with the biofilm for the waste water being treated on the surface of the fix contact units. Total time spent in the system is 2 days. The final complex polishing treatment is provided by the high pressure floating DAF equipment conditioned with chemicals. The results of 3 years of operation have proved the efficiency and cost effectiveness of the system. Based on organic pollutant content, the order of magnitude of the pretreatment system is 200.000 PE. From a global perspective, the system/structure is the first Hungarian patent (registered under 229.918 patent number, I. Gyulavári 2010) has ever built.

The paper presents studies and researches in the field of bending of metal parts (thickness between 1 and 3 mm) on CNC machines. This paper tries to provide answers to the many problems arising in the companies due to the quality of the economic goods. The paper proposes laborious research and studies on determining the drawings of metal parts with the thickness g=1.5 mm, considering that other variables such: the temperature variation during the processes of punching and bending, tool usage, the tolerance between the surfaces of the bending tools, the vibrations of the machines, their usage and the roughness of the sheet metals may influence the quality and precision of the products. The calculation of the drawing (the geometry in plane of the piece) becomes important because it must include the deformation caused by the bending operation. Bending coefficients Kî  must compensate for deviations from the final dimentions of the metal parts, because of the many variables that can adversely affect their execution. During the study we obtained the bending coefficients for the components made out of metal sheet OL 37 with 1.5 mm thickness. The bending coefficient Kî is determined by experimental tests and measurements, depending on the material thickness, chemical composition, its quality, bending complexity, the movement between the surfaces of punching and bending tools, vibration of the machines, their usage, the roughness of the sheets metal as a result of lamination process and other variables that may influence the quality and precision of the products.

traffic congestion is a recurring problem not only in India but worldwide. In many states traffic is being a major hurdle due to urbanization and auto-mobilization. Karnataka is one of such states with fast growing cities such as Bengaluru have wide scope of rapid growth in economy and population; there is a raising trend of traffic congestion resulting in delay in reaching the destination. Bengaluru city has experienced a phenomenal growth in vehicle population in recent years due to city expansion, urbanization and independent culture.

According to survey; the time taken to travel the same distance has seen a regular increase as Bengaluru’s traffic-choked roads are seeing an addition of roughly 5lakh vehicles each financial year, with the total number of vehicles in Bengaluru breaching the 60.59lakh mark this year. By February2016, the number of ‘non-transport’ vehicles such as two-wheelers and cars in the city had reached 54.67lakh. According to Transport Department, 41.86lakh two-wheelers dominated the city’s roads, followed by 11.8lakh cars. The number of transport vehicles stands at over 5.91lakh, 1.05 lakh taxis and 40,365 Buses. The city has seen a steady increase in the number of vehicles being registered from 41.56lakh in March2012 to 55.59lakh in March2015, and now over 60.59lakh by February2016. According to Transport Department at least 1lakh more vehicles had been added to this tally March2016. Statistics clearly indicate that the number of public transport is less and people opt for private vehicles as there is no proper arrival and departure times, delay due to unpredictable traffic, connectivity to exact destinations, convenience and reliability issues.  

With Bengaluru’s 12.33 million population bus transport is the most economical and affordable transport system from societal perspective. The rapid increase in the number of vehicles on the road has escalated the need for managing traffic flow efficiently to optimize utilization of road capacity. Public transport has huge delays to each stop due to traffic congestion during peak hours.  A wells structured unique lane for BRTS can provide a high level of mobility, on time arrival, departure, reduction in the waiting time of passengers. The paper is a proposed idea for controlling and managing peak time traffic. With the trend of worldwide urbanization, an increasing number of vehicles are swarming into city road networks of limited capacity, leading to excessive increase of traffic congestion. As a result the major conglomerate junctions are operating over the capacity and average journey speeds on some of the key roads in the Central Area are lower than 10kmph in the peak hour. Therefore it has become necessary to establish plans for efficient traffic management in Bengaluru. The target of the study is to make uniform travel time for the people at both peak and non peak hours. This paper attempts to understand the application of Intelligent Transport System (ITS) in Indian context with case studies as a solution to the current traffic management practices. The use of modern amenities and efficient data communication has now become the basic requirements of all the services.

Annona muricata L. (Magnoliales: Annonaceae) is a tropical fruit tree with a long history of traditional use. The object of this research was to determine the genetic diversity of the Annona muricata L. species using SSR markers. Thirty-four accessions of A.muricata leave samples and a leaf sample of A.cherimola as a control were collected from different locations in Sri Lanka. Genetic diversity of A.muricata was evaluated using eight microsatellites markers developed in Annona cherimola. Optimum annealing temperature of each primer was selected after the gradient PCR. Total nine genotypes were detected with 1.125 alleles per locus. The low levels of mean observed and expected heterozygosity ranged from 0.0147 and from 0.0140, respectively. The average Polymorphic Information Content (PIC) value for all markers used was 0.0131, the highest PIC value 0.1046 was obtained for the primer LMCH9.The high level of PIC value and polymorphism indicate that the primer LMCH9 is well suited for diversity assessment of Annona muricata germplasm. Accessions 168, 25, 82 & 49 were gave heterozygous alleles band for primer LMCH9. As a result, it was revealed a relatively limited genetic diversity within selected Annona accessions with respect to Annona cherimola markers.

David Joseph Bohm was born on December 20, 1917, and obtained the doctorate in physics in 1943 from the University of California, Berkeley, under the guidance of R. Oppenheimer[1]. From 1946 he began teaching at Princeton University. He has published a series of articles on various physics topics, especially on plasma oscillations. He then wrote the book Quantum Theory considered to date a classic in the subject. In 1950 he was indicted and imprisoned for political reasons, and although acquitted in May 1951, Princeton University refused to renew his contract and he was exiled to Brazil. In 1954, David Bohm elaborated the work entitled A proposal for interpretation of quantum theory in terms of "hidden variables"(3), which sought a causal and objective description of quantum phenomena. In 1960 he enthusiastically discovered the thinking of the Indian Jiddu Krishnamurti, and from dialogues between them emerged interesting ideas in the area of the confluence of Physics with the mystical tradition.

Currently, the standard method of cardiac output monitoring is to use a Swan-Ganz catheter. This catheter can lead to complications, and therefore the benefits over risks are being analyzed. In order to have a continuous monitoring of cardiac output or circulatory dynamics in a less invasive form, two different devices were developed. The first device that was developed is the Vigileo monitor (Vigileo) (Edwards Lifesciences corporation, CA, USA) and the second device is the LiDCORapid (Lidcolimited, London, UK). The comparison analysis of the cardiac output was measured between the Vigileo and LiDCORapid. A blood pressure calibrator made by BIO-TEK INSTRUMENTS called BIO-TEK601A was used for the artificial pressure source. Aortic pressure (Ao) and radial artery pressure (Rd) was obtained through the BIO-TEK601A. The CO was displayed from the data that was divided into each model, gender, age and input waveform. For statistical evaluation of the experimental data, Mann-Whitney U-test or Wilcoxon Signed rank sum test were used. The CO results from the Vigileo model were less dependent on the Ao or Rd pressure compared to the LiDCORapid model.  The Vigileo was determined to have less variability with CO results compared to the LiDCORapid model.

The temporal variation of sea level can be observed as hours, days, weeks, months, seasonal, annual, inter annual and as long term. Meanwhile, some extreme variations are governed by disturbed weather system such as storms, meteo-tsunami etc. A series of tide-gauge data were obtained from the Intergovernmental Oceanographic Commission (IOC) whereas from a global satellite based database, i.e. Achieving, Validation and Interpretation of Oceanographic Satellite (AVISO) data. Eight years of automated sea level gauge data in one minute frequency were used to analyze daily, weekly and seasonal variations while twenty years of satellite data were analyzed for long term variations. The outcomes of both data were super positioned to appraise the accuracy of the data sources. The T_TIDE harmonic analysis function of time series analysis in MATLAB’ software was used to quantify the tidal constituents. According to the form factor (0.33), the type of tide was mixed semi diurnal. The spring tide range was 0.652m according to the statistical quantification of Hikes 2006. The average seasonal variation was 20-30 cm where the highest variation was identified during December and January while the minimum was identified during July and August. The observed long term sea level variation indicates a positive trend of 1.9 mm yr-1 in the west coast of Sri Lanka.
