Comparative Study of Various Image Processing Tools with BigData Images in Parallel Environment

BigData refers to the collection of various kinds of data in a large amount. This data needs to be process through some tools as it can have some useful information. In order to process this data, Hadoop came in existence. It processes the data in parallel distributed environment. BigData contains various forms of data such as text, images, videos etc. In this paper we are going to discuss about image data. We need to perform image processing to process these BigData images. As BigData is very huge so the number of images to be processed is also very large. Image processing can be performed in parallel environment in order to speed up this process. There are various tools to process the images in parallel environment, such as: HIPI, OpenCV, CUDA, MIPr etc. In this paper we have performed a comparative study on these tools

Porous ceramics for multistage Knudsen micropumps—modeling approach and experimental evaluation

This paper describes the evaluation of four types of porous ceramics for use as thermal transpiration materials in Knudsen pumps that operate at atmospheric pressure. Knudsen pumps are motionless gas pumps that utilize thermal transpiration along a channel or a set of channels; the channels must have a temperature gradient and must constrain the flow to remain within the free molecular or transitional flow regimes. Of the ceramics evaluated, a clay-based, 15 bar synthetic ceramic (15PC) presents the most favorable properties for Knudsen pumps. For an input power of 3.4 W, a 25 _ 25 mm 2 nine-stage Knudsen pump that uses this material provides a maximum pressure head of 12 kPa and a maximum gas flow rate of ≈3.7 µL min _1 . Reliability tests demonstrate more than 11 750 h of continuous operation without any deterioration in their gas pumping capabilities. A fitted model suggests that the temporal evolution of pressure at the sealed outlet of a Knudsen pump can be captured adequately using four parameters. These parameters correspond to various nonidealities that play dominant roles in the transient response of these pumps.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90805/1/0960-1317_21_9_095029.pd

Stem Cell Antigen CD34 In Native And Engineered Form Alter Its Binding Ability To Stromal Cells And Ligands: A Classical Example Of Clinical Benefits Of Therapeutic Genetic Engineering Of Stem Cells In Transplantation

CD34 is a highly glycosylated surface-expressed sialomucin and, because it is present on hematopoietic stem cells (HSCs), has demonstrated immense clinical utility in their enumeration in aphaeresis products, immunoaffinity purification for transplantation, and disease monitoring. The success of CD34 based reagents in identifying hematopoietic progenitors led to the assumption that CD34 is expressed on cells with regenerative potential and is sufficient for hematopoietic reconstitution in marrow-ablated recipients. However, its role has not been identified in substantial detail. 

With the advent of the fact that CD34 binds adapter protein like CRK-L in cytosol and CD34 knock out studies identified a a signaling role, CD34 antigen has been proposed to play a signaling function. Since it is a sialomucin, a member of the group adhesion molecules, we attempted to identify a role by over-expreesing its gene in cell lines. We report here that CD34 and engineered forms (Ser306 & Tyr318) significantly regulates adhesion to stromal cells, like mesenchymal stem cells and bone marrow ligands. These enhance binding of cells overexpressing CD34 by upregulating integrins and we therefore propose that such cells may effectively potentiate the success of transplantation through greater homing if they are used for transfusion

A quick method for surveillance of 59 pesticide residues in fruits and vegetables using rapid three-dimensional gas chromatography (GC/MSD/µ-ECD/FPD) and LC/MS-MS

This article describes a simple, quick and inexpensive method for determination of pesticides in fruits and vegetables. The method, known as the quick, easy, cheap, effective, rugged and safe (QuEChERS) method for pesticide residues, involves the extraction and simultaneous liquid-liquid partitioning formed by adding anhydrous magnesium sulfate (MgSO4) plus sodium acetate (NaAc) followed by a simple cleanup step known as dispersive solid-phase extraction (dSPE). The extracts were analyzed by three-dimensional gas chromatography GC/MSD/µ-ECD/FPD in trace ion mode and liquid chromatography/tandem mass spectrometry (LC/MS-MS). Method sensitivity, linearity, repeatability and reproducibility, accuracy, matrix effects, and overall uncertainties have been studied for method validation according to the international norm ISO/IEC: 17025:2005 for both techniques. Identification, quantification and reporting with Total and Extracted ion chromatograms, µECD and DFPD were facilitated to a great extent by Deconvolution Reporting Software (DRS) for GC and Mass hunter software for LC. For all compounds LODs were 0.001 to 0.01 mg/kg and LOQs were 0.005 to 0.020 mg/kg. Correlation coefficients of the calibration curves were >0.991.To validate the effects of matrices, repeatability, reproducibility, recovery and overall uncertainty were calculated for twenty-four matrices at 0.020, 0.050 and 0.500 mg/kg. Recovery ranged between 75-107 % with RSD <17 % for repeatability and intermediate precision and UM of ± 13-22 %

Investigating the Role of the Exocyst Complex in Infection-related Development of the Rice Blast Fungus Magnaporthe Oryzae

Host colonization is mediated through the secretion of effector proteins in order to neutralize host immune responses. However, the mechanism of the effector delivery during biotrophic invasion is not well defined in M. oryzae. In this thesis, I define the role of the exocyst complex, an evolutionarily conserved octameric protein complex involved in vesicle docking to the plasma membrane (composed of Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70 and Exo84), during infection-related development in M. oryzae. Like other filamentous fungi, M. oryzae, exocyst components localize to the vegetative hyphal tip distinct from the Spitzenkörper. However, at the initial stage of infection-related development all the exocyst components localise as a ring at the cortex of the appressorium and re-assembles around the appressorium pore in an actin-dependent manner in mature appressoria. I report that the septin network is required for the transition of exocyst ring from periphery to the appressorium pore. Deletion of Exo70 and Sec5 showed significant reduction in protein secretion and plant infection. I show that Sec6 is required for the exocyst assembly around the appressorium pore and effector secretion from the appressorium. I report that, during biotrophic invasion, effectors are secreted through a distinct pathway. Apoplastic effectors, Bas4 and Slp1 are secreted via a Golgi-dependent pathway while secretion of cytoplasmic effectors, Pwl2 and Bas1 meditates through a Golgi-independent pathway in which exocyst components Exo70 and Sec5 are involved.The Halpin Scholarship for Rice Blast Researc

Challenges, Effects, Coping Strategies, and Measures of Financing Agriculture: Socio-dynamics of Conventional and Islamic Sources of Finance in Kaduna State, Nigeria

Kaduna State in Nigeria is a predominantly agricultural society with active farmers within the median age group of between 35- 54 years who are into food crop production with maize as the major food crop and ginger as the major cash crop produced in Kaduna State. Their business activities are spread almost evenly across the geographical zones in Kaduna State. The main aim of this paper is to examine the causal relationships of the effects of the challenges of financing agriculture on the challenges of financing agriculture and also evaluate the effects of the measures to mitigate the challenges of financing agriculture on the coping strategies adopted in financing agriculture in Nigeria. Data were collected using the questionnaire as the instrument of data collection in a quantitative method based on the cluster sampling technique, 663(50%) questionnaires were administered across 17 different clusters across the three (3) geographical zones in Kaduna State and some centralized offices of financial institutions within Abuja and 562 responses were received with a sample error margin of -17.9%. An Ordinary Least Square (OLS) linear regression test conducted revealed the effects of challenges of financing agriculture on the lack of collateral to obtain a loan with a B .820 and managerial/government bureaucracy in financing agriculture coming second with a B .638. Privatization of energy is a major challenge to agro manufacturing and the value chain with B .585 is in third place while lack of finance for mechanization and irrigation technology is in fourth place with B .572. In addition, the study also revealed the impact of the measures on the coping strategies is strongest on Zakat with a B 1.679. The effect of the measure on contribution from family and friends as a coping strategy comes in second place with a B .912. The study also revealed insecurity and infrastructural development as other impediments to financing agriculture in Nigeria based on the explored open-ended question. It is recommended that a central zakat fund be established to provide stable non-interest finance to smallholder farmers.

VITAMIN C AND ITS ROLE IN BODY

Ascorbic acid or Vitamin C is very important in our body because of its antioxidant property. But the main problem; that vitamin C uses is to maintain the stability as well as its drug distribution system. Vitamin C also plays a protective role in diabetes, cancer, heavy metal toxicity or poisoning, etc. Vitamin C is found in many sources present in nature, including tomatoes, broccoli, etc. Many factors in the body, as well as outside the body, affect the content of vitamin C in the body or sources like the season, climate, and pollution affect the content in fruits and vegetables besides sex, age, pregnancy, lactation, etc. affect the vitamin C content in the body. It is extensively used in the common cold, wound healing process, cancer, heavy metal poisoning or toxicity, and even in men's fertility. In this article, we focused on the general aspects: its bioavailability, sources, its toxicity and deficiency, and factors affecting vitamin C level as well as its use in humans. In the last, we conclude, the excess or lack of Vitamin C, both conditions have affected the human body in a significant range. It plays a protective role against many disorders and is required for kids, men, women, and even old-aged patients
