Ion counting efficiencies at the IGISOL facility

At the IGISOL-JYFLTRAP facility, fission mass yields can be studied at high precision. Fission fragments from a U target are passing through a Ni foil and entering a gas filled chamber. The collected fragments are guided through a mass separator to a Penning trap where their masses are identified. This simulation work focuses on how different fission fragment properties (mass, charge and energy) affect the stopping efficiency in the gas cell. In addition, different experimental parameters are varied (e. g. U and Ni thickness and He gas pressure) to study their impact on the stopping efficiency. The simulations were performed using the Geant4 package and the SRIM code. The main results suggest a small variation in the stopping efficiency as a function of mass, charge and kinetic energy. It is predicted that heavy fragments are stopped about 9% less efficiently than the light fragments. However it was found that the properties of the U, Ni and the He gas influences this behavior. Hence it could be possible to optimize the efficiency.Comment: 52 pages, 44 figure

Sensitivity of measured fission yields on prompt-neutron corrections

The amount of emitted prompt neutrons from the fission fragments increases as a function of excitation energy. Yet it is not fully understood whether the increase in \nu(A) as a function of E_{n} is mass dependent. The share of excitation energies among the fragments is still under debate, but there are reasons to believe that the excess in neutron emission originates only from the heavy fragments, leaving \nu_{light}(A) almost unchanged. In this work we investigated the consequences of a mass-dependent increase in \nu(A) on the final mass and energy distributions. The assumptions on \nu(A) are essential when analysing measurements based on the 2E-technique. This choice showed to be significant on the measured observables. For example, the post-neutron emission mass yield distribution revealed changes up to 10-30%. The outcome of this work pinpoint the urgent need to determine \nu(A) experimentally, and in particular, how \nu(A) changes as a function of incident-neutron energy. Until then, many fission yields in the data libraries could be largely affected, since they were analysed based on another assumption on the neutron emission.Comment: 4 pages, 3 figures, Proc. 2013 International Conference on Nuclear Data for Science & Technology (ND2013), March 4-8, 2013, New York, USA, to be published in Nuclear Data Sheet

Sprinkler Irrigation Systems and Water Saving, A Case Study from South of Iraq

The irrigation systems modernization is a part of water resources management improvement process which requires a decision support system, the core of such system is an automated procedure for simulating the relevant processes governing the system. Simulation models have been used in two phases in this research for two specified areas within Maysan and Wasit provinces in Iraq with an area of 480×250 meters for each province, which have been taken as a case study to redesign and replace the existing open channel network with the new sprinkler irrigation system. The first phase is to find a crop water requirement and irrigation requirements for maize, wheat and barley using CROPWAT 8.0 simulation model, while the second phase includes the irrigation network design using EPANET 2.0 simulation model to perform extended period simulation of hydraulic behavior within pressurized pipe networks, in addition to, the SPAW model which have been used to evaluate soil characteristics. This study has revealed that the designed sprinkler system capacity is 113m3/hr with 5.04 mm/hr precipitation rate. The designed sprinkler system can be used to irrigate different crop types including maize, barley and wheat. Since, the sprinkler system has been designed to meet the maize irrigation water requirements which is the heights requiring water consumer crop the during the summer season, then it has the ability to meet the different winter cereals irrigation requirements. The designed system can be used in the different regions of Iraq generally and southern regions, especially because it has been designed to suit the soil that characterized by moderate, slow infiltration rates in addition to suit areas of relatively high wind speed which affecting the water distribution uniformity and slow infiltration rates of soils

The Role of Tuberin in DNA Damage Repair During Cell Proliferation

The cell cycle contains DNA damage checkpoints that delay mitotic progression and allow for DNA repair before cell division. DNA damage can be caused by radiation, drugs, and other processes which lead to cellular mutations and carcinogenesis. The tumour suppressor protein p53 is activated in the presence of DNA damage. It induces apoptosis or cell cycle arrest which allows cells to repair themselves. Tuberin (TSC2), another tumour suppressor protein, regulates the G2/M transition in the cell cycle and negatively regulates protein synthesis and cell growth. Mutations in tuberin can lead to the multisystem autosomal dominant disease known as tuberous sclerosis (TSC). Previously, our lab has shown that Tuberin regulates mitotic onset through cellular localization of the G2/M Cyclin, Cyclin B1. My project focuses on the Tuberin/Cyclin B1 complex in relation to G2/M arrest and DNA damage repair. In this study, we will overexpress Tuberin-WT and Tuberin clinical mutants in NIH-3T3 (mouse) and U2OS (human) p53 wild type cells. Etoposide, a topoisomerase II drug, will be used to induce DNA damage. Cells will then be analyzed by flow cytometry, TUNEL assay, and western blot to assess their cell cycle profile, apoptotic levels, and protein expression. Using CRISPR-Cas9 technology, a NIH-3T3 null TSC2 cell line will be created to clarify the role of Tuberin during DNA repair. Preliminary results have determined that 4μM of etoposide treatment at 8 hours arrests 50% of NIH-3T3 cells at G2/M. This project will provide greater insight into DNA damage induced carcinogenesis, TSC, and other proliferative diseases

Experimental evaluation of receptor-ligand interactions of dual-targeted particles to inflamed endothelium

Vascular-targeted carriers (VTCs) are often designed as leukocyte mimics, conjugated with ligands that target leukocyte adhesion molecules (LAMs) to facilitate specific adhesion to diseased endothelium. VTCs must adhere in regions with dynamic blood flow, frequently requiring multiple ligand-receptor (LR) pairs to provide particle adhesion and high disease specificity. To study LR kinetics under flow, multiple research groups have used protein-coated plates to study the adhesion and rolling of dual-targeted particles in vitro.1-4 While important knowledge is contributed by these studies, they lack the complexity of a diseased physiologic endothelium, as spatiotemporal LAM expression varies widely. Despite decades of research with the ambition of mimicking leukocytes, the specificity of multiple LAM-targeted VTCs remains poorly understood, especially in physiological environments. More specifically, there is a lack of mechanistic understanding of how multiple ligands interact with biologically complex endothelial surfaces under dynamic in vivo environments.
