Published: March 2018

ABSTRACTIncreasing in fertilizer price has caused increase in hydroponic system cost. The objective of the research was to determine the best fertilizer source that could replace AB mix by examining several sources of nutrients, i.e. NPK 15:15:15, NPK 12:14:12 for hydroponic cultivation of spinach, pakchoy, and lettuce. The research was conducted in the Green House Dramaga Field Unit, University Farm, IPB Bogor from February to April 2013. The treatments (AB mix, NPK 15:15:15, and NPK 12:14:12) were arranged in randomized completely blok design with 4 replications. The results showed that fertilizer treatments used did not affect the vegetative growth of spinach, pakchoy, and lettuce, but AB mix fertilizer treatment gave the highest yield in spinachplants, pakchoy, and lettuce in yield components i.e. an average weight/plant and weight ofmarketable yield, respectively at 21.65 g, 235.75 g spinach, 46.06 g, 465.75 g pakchoy, and 25.93 g lettuce. In lettuce experiment, no marketable yield was obtained. Based on these results NPK15:15:15 and NPK 12:14:12 fertilizer could not replace AB mix as a source of plant nutrients inspinach, pakchoy, and hydroponic lettuce.Key words: AB mix, hydroponic , leafy vegetables , NPK 15:15:15, NPK 12:14:12 ABSTRAKKenaikan harga pupuk menyebabkan kenaikan biaya dalam sistem hidroponik.

Early detection of newly arrived exotic plant pests and diseases is critical to protect New Zealand’s environment and agriculture. For that purpose, the Ministry for Primary Industries (MPI) conducts active surveillance of numerous high risk organisms, such as fruit ies or gypsy moth, via speci c targeted surveillance programmes.
In addition, MPI utilises passive surveillance to enable early detection and reporting of exotic pests and diseases. Members of the public, industry groups, plant health professionals, and diagnostic laboratories report detections of suspected exotic pests and diseases via the “exotic pest and disease hotline” (0800 80 99 66), which operates 24 hours a day, 7 days a week. Noti cations are promptly investigated by MPI and deduced biosecurity risks can thus be addressed using appropriate containment, eradication, or long-term management measures.
An overview of passive surveillance data (2015—2017) is presented, with the focus on noti cations and investigations of exotic plant pests and diseases associated with recently imported goods. Particular attention is given to cases dealing with high-risk organisms such as the brown marmorated stink bug (BMSB).

Published: March 2018

Abstract
Many upcoming new generation reactors employ natural circulation for heat transfer in normal mode of operation. Natural circulation systems are simpler and safer than their forced circulation counterparts. However, these systems are prone to flow instability which are undesirable due to several reasons. In the present work, a rectangular glass loop, wherein cooler is just above the heater, has been considered for experimental and numerical investigation at atmospheric pressure. Heat addition from room conditions has been studied to understand the natural circulation loop dynamics, checking the possibility of occurrence of instability with the new orientation of the heater and the cooler. Experiments were performed at different power levels and coolant flow rates. CFD analyses were performed for all the cases investigated experimentally using the commercial CFD code ANSYS FLUENT 14.0. No instability was observed during the experiments and none during the simulations done for the duration of the experiments.
Investigation of the excitation functions for the (n, 2n) reactions on the structural fusion material 58,60 – 62,64Ni

Published: March 2018

Abstract
The theoretical prediction of the cross-sections in the determination of the structure materials used in the fission and fusion technology is very important in terms of reactor safety. Also, theoretical cross-sections are necessary to evaluate the performance of structure materials, especially, in the lack or absence of experimental data. Nickel base alloys are one of the wide ranges of structural materials used in fission and fusion reactors. Therefore, the excitation functions of the (n, 2n) reactions on the structure material nickel with neutrons producing via fusion reactions are investigated in this study. Thus, the excitation functions for 58,60 – 62,64Ni(n, 2n) reactions are calculated using some pre-equilibrium models which are the hybrid, the geometry depended hybrid and the two-component excitation models. The calculations are performed in the ALICE/ASH and the Talys 1.8 codes. Also, the equilibrium and pre-equilibrium effects on these reactions are investigated in this study. The obtained cross-sections are discussed and compared with the experimental data and the theoretical predicted data.

Published: March 2018

AbstractIn this study, AISI 321 austenitic stainless steel samples were surface treated using severe shot peening (SSP) with 1 000 % and 1 300 % coverages. Microstructural features including the grain size, phase transformation, and formation of sub-surface microcracks were investigated at the rough top surface and about 40 μm depth (top surface after grinding and removal of initial rough surface layer created by SSP). In addition, microhardness variations were thoroughly analyzed in-depth. Experimental results demonstrated that for both 1 000 % and 1 300 % coverages, the microstructures of top surface and 40 μm depth are respectively composed of equiaxed nano-grains and lamella-shaped cells; however, enhanced imparted strain in the case of 1 300 % coverage leads to the formation of considerable amounts of strain-induced martensite (α′) phase in the surface layers and consequently, due to strength increase and lack of deformability, some microcracks are created in the sub-surface layers (up to 20 μm depth).

Published: March 2018

<p>Spinal cord involvement secondary to non Hodgkin lymphoma (NHL) is rare and associated with quick development of neurological defects. The overall risk of central nervous system relapse in aggressive NHL ranges 2%–27% and is associated with a poor prognosis. Hence early detection is important for staging and prognostication. Magnetic Resonance Imaging (MRI) is the routinely used potential imaging modality for spinal cord metastasis. Several studies have shown the values of 18F FDG (flurodeoxyglucose) PET- CT for staging, restaging, and therapy monitoring in NHL. PET has 96% sensitivity in the detection spinal metastasis. This reported case was a 35 years old male, diagnosed as peripheral T cell lymphoma on June 2014 and was treated with chemotherapy. In January 2016 he developed swelling of lower limbs and paraparesis with bladder and bowel involvement. Duplex color Doppler of lower limbs showed normal flow and Complement Fixation Test for filariasis was negative. MRI T2W showed hyper intensity signal extending from lower cervical to all dorsal cord. The 18F FDG PET-CT was performed to restage the disease and showed intense FDG uptake in the spinal cord, extended from the lower cervical to 11<sup>th</sup> thoracic and at the level of 3<sup>rd</sup> and 4<sup>th</sup> lumbar vertebrae. The spinal cord hypermetabolism observed on PET CT scan correlated with MRI characteristics and significantly aided in the diagnosis of spinal cord involvement. This case is reported to emphasize the usefulness 18F FDG PET-CT in restaging and follow-up of patients with NHL. PET-CT imaging can reliably identify hyper-metabolic central nervous system involvement and help not only to restage patients but also to guide new therapeutic strategies.</p><p>Bangladesh J.
