ABSTRACT The purpose of this research was to investigate the effectivity of arbuscular mycorrhizal fungi (AMF) inoculation on shallot yield with three techniques of irrigation. This research was conducted at Gagasari Village, Cirebon from May to August 2016. This research was arranged in split plot design with two factors. Irrigation technique as main plot consisted of three levels i.e. without water logging, intermittent, and using water logging. Rates of AMF as sub plot consisted of three levels i.e., 0, 10, and 15 g per plant. The result showed that rates of AMF affected water content of plant. The rates 15 g per plant of AMF gave the highest of water content of plant (65%). Furthermore, the highest of biomass was resulted by water logging treatment. Phosphorus content of plant was not affected by AMF inoculation. Inoculation of AMF increased shallot bulb weight per plant when it was combined to intermittent and water logging treatment. Based on regression test to AMF rates at water logging treatment, the optimum rates to increase weight of shallot bulb was 6.71 g AMF per plant. That rates potentially gave 23.53 g per plant of shallot bulb.Keywords: intermittent, phosphorus content, water content, water logging ABSTRAK Penelitian ini bertujuan untuk mengetahui efektivitas dari inokulasi cendawan mikoriza arbuskula (CMA) terhadap produksi bawang merah dengan tiga teknik pengairan yang berbeda.

A distribuição espectral de raios X de megavoltagem utilizados em departamentos de radioterapia é uma grandeza fundamental a partir da qual, em princípio, todas as informações requeridas relevantes para tratamentos de radioterapia podem ser determinadas. Para o calculo das doses administradas ao paciente que faz radioterapia se usam sistemas de planejamento de tratamento (TPS, do inglês Treatment Planning System), que fazem uso de algoritmos de convolução e superposição os quais requerem um conhecimento prévio do espectro de fluência de fótons para realizar o cálculo acurado das doses tridimensionais e assim assegurar uma melhor probabilidade de controle tumoral mantendo baixa a probabilidade de complicações do tecido normal. Neste trabalho foi obtido o espectro de fluência de fótons de raios X de um acelerador linear clínico SIEMENS ONCOR de 6 MV, usando um método de caráter inverso para a reconstrução dos espectros, a partir das curvas de transmissão de fótons medidas para diferentes espessuras de alumínio; o método usado para a reconstrução dos espectros é uma técnica estocástica conhecida como recozimento simulado generalizado (GSA, do inglês Generalized Simulated Annealing), baseado no trabalho da estatística de quase equilíbrio de Tsallis. Para a validação dos espectros reconstruídos foram calculadas as curvas de porcentagem de dose em profundidade (PDD, do inglês Percentage Depth Dose) para a energia de 6 MV do acelerador, usando simulação Monte Carlo com o código PENELOPE, e a partir da PDD se fez o cálculo o índice de qualidade do feixe TPR20/10.

Abstract
The method for the evaluation of the control room habitability is presented in this paper with focus on Maanshan PWR nuclear power plant (NPP) using the codes RADTRAD, HABIT, and ALOHA. Therefore, this paper is divided into two parts: The first part is the evaluation of the cumulative dose at the control room, the exclusion area boundary (EAB) and the low population zone (LPZ) in case of an design basis loss of coolant accident (DBA/LOCA). For this first part, the Maanshan NPP models of the code RADTRAD/SNAP were used for the analysis. The second part is the evaluation of the control room habitability under the assumption of CO2 storage burst. For this part, the HABIT and ALOHA codes were used. As result it was seen that the RADTRAD calculation results are below the failure criteria of standard review plan (SRP) and 10 CFR 100.11. The HABIT and ALOHA results are below the R.G. 1.78 failure criteria. These results indicate that Maanshan NPP’ habitability can be maintained under the above conditions.

<p><strong>Objectives</strong>: With the advancement of science, the scope of 131 I thyroid uptake in diagnosis and treatment of thyroid diseases has become limited. Uptake test with 99m Technetium (99mTc) pertechnetate along with a thyroid scan, which are done almost routinely, could be a better option when required. This will not only exempt the patients from relatively higher radiation burden of 131I but will also cause significant reduction of procedural time. Moreover, the thyroid image we get along with the uptake may guide with additional information. This study was done to provide preliminary data regarding thyroid uptake test with 99mTc in our population &amp; to assess the possibilities of introducing this safer and convenient radionuclide in our routine practice.<strong> </strong></p><p><strong>Patients and methods:</strong> This cross sectional, comparative study was conducted from January to December of 2015 on 27 participants in Institute of Nuclear Medicine and Allied Sciences, Dhaka. Hyperthyroid patients coming for a radioactive iodine uptake test along with a thyroid scan were enrolled. Uptake of 99mTc pertechnetate at 20 minutes and 131I at 24 hours were measured. </p><p><strong>Results: </strong>Among 27 participants, 25 had raised, 2 had normal 131I uptake. Two normal values of 99m Tc uptake were found and rest showed high uptake. Two patients had high uptakes in both the method but 131 I uptake was extremely high (90% and 80%) in comparison to 99mTc uptake (10% and 7% respectively). Statistical analysis revealed a moderate agreement (k=0.5) along with a moderate positive correlation (r=0.6) between the two uptake methods.</p><p><strong>Conclusion:</strong> Good agreement and correlation were found between two modalities of thyroid uptake in case of hyperthyroid patients. So, 99mTc may be considered for uptake test in a regular basis in the limited fields where an uptake is still required as it may yield a reliable result in a simple, quicker and more convenient way.</p><p>Bangladesh J.

Switching Anti-Vascular Endothelial Growth Factors in Refractory Neovascular Age-Related Macular Degeneration
Authors: Ashraf Mohammed , Banaee Touka , Silva Fabiana Q. , Singh Rishi P. 
Published: March 2018

BACKGROUND AND OBJECTIVE:
Anti-vascular endothelial growth factor (VEGF) therapy is the treatment of choice for cases with neovascular age-related macular degeneration (AMD). Switching to an alternate anti-VEGF has been suggested as a possible option for resistant cases. The purpose of this review is to evaluate whether the timing of switching affects treatment outcomes.

PATIENTS AND METHODS:
A review of published literature was performed looking at all studies where patients with refractory neovascular AMD were switched to an alternative anti-VEGF. Studies were then stratified based on the timing of switching into early (< 12 previous injections) and late (> 12 previous injections).

RESULTS:
A total of 38 studies were identified: 18 where patients were switched early and 20 where they were switched late. Both subgroups showed anatomic improvement after switching, with limited visual gains.

CONCLUSION:
There are insufficient data to recommend early versus late switching. However, both groups showed a reduction of fluid on optical coherence tomography and visual gains in 25% to 30% of patients.

A New Multi-Method Well Placement Approach In Optimizing a Challenging Thin Reservoir Well Injectivity
Authors: Bazara Magdi , Khalil Dia , Al-Zarafi Alaa , Al Abri Abdelrazzaq , Farah Ahmed , Al Busaidi Adil 
Published: March 2018

This case study is done on a mature oil field. In this field, a thin dolomitic layer is thought to be acting as a baffle of water injector in the field. As this thin layer is less than 50 cm thick and not consistently recognizable using some conventional logs, this is a trial of using a combination of advance distance to boundary detection and ultra-high-resolution imaging tool to steer the well above this thin layer. Based on core available data, it is a dolomitized Redstone with a strong hydrocarbon stain. The tight, relative dolomite is likely to act as a baffle to vertical fluid flow. To enhance the effect of planned water injection project, placement of horizontal well just above the dolomitic layer by a meter or a meter and a half was the target for a successfully injector well in this field. Challenges to the landing of such a well includes depth, thickness, and dip uncertainties. Additionally, there are the errors that are inherent to correlating between the reservoir scale and the seismic scale. Finally, it is difficult to discern boundaries in this low-resistivity environment characterized by very low resistivity contrast. Resistivity contrast, in particular, is of major importance as it plays the main role in determining the operability of common distance-to-boundary tools.
Combination of distance to boundary detection capability and Ultra-High Resolution Imaging while drilling allowed to place wellbore precisely at certain distance from the dolomitic fluid barrier, avoid any unwanted exits and to evaluate this dolomitic layer properties by resistivity, density/neutron data known as triple-combo sideways with the above mentioned used technology for steering. The data provided were integrated with seismic surveys to refine the reservoir structure and geometry interpretation. The improved understanding made it possible to optimize recovery and production through optimum landing of the well and to map the overlying and underlying reservoir parameters.
By selecting the right tool configurations in the bottom-hole assembly (BHA), formation tops were detected from a distance of up to 2m true vertical thickness (TVT) and in the same time parallel to the dolomitic layer in most of the well trajectory. Resistivity contrast was as low as 0.3 ohm.m versus the 0.9 ohm.m when detecting the dolomitic layer marker unit. On the other hand, in some areas of the well, crossing the dolomitic layer and a one bouncing to it was needed to build the confidence in this method and confirming the steering interpretation for the future upcoming wells in the same field.
