Published: February 2019

Currently, studies on the mechanisms of the pathogenesis of plant diseases and their distribution in crops are intensively conducted in Russia and the world. First of all, this interest is associated with a significant effect of pathogens on the harvest. In Western Siberia, brown rust and powdery mildew are almost annually recorded in the crops of spring and winter wheat, reaching in some years up to the epiphytotic level. In this regard, methods for monitoring the condition of crops in order to predict their dynamics and plan agrotechnological events to control the state of plants in crops, including the development of fungal infection are developing. Models of fungal infections development on the wheat leaf (for example, brown rust) are used to monitor, predict and control the state of crops in order to optimize the growing process. Mathematical models allow computational experiments to make predictions about the risk dynamics of infections in different scenarios of global weather changes. Such designation of models assumes their hierarchical structure characteristic of multilevel modeling systems. This review presents models for the development of foliar fungal infections in crops, and formulates the methodological aspects of system modeling that can be used for adapting existing models and their units, and developing new models based on them. The article presents the structure of the hierarchical system for modeling the development of leafy infection, provides an overview of the units constituting the system, and discusses the issues of parametric adaptation of submodels. We demonstrated that, to date, plant growth and development models have been developed with varying degrees of detail. Currently, to develop a system for modeling the development of an infection in a crop, it is necessary to determine a large body of available experimental data and, by taking into account this data, we can put together a model as a system consisting of model modules, for which the models of basic processes have already been developed and described.

Published: February 2019

This research aims to examine the impact of fundamental and technical factors towards stock returns, and with macroecomoic as moderation variable. The population used in this research is all public companies or issuer listed in Indonesia Stock Exchange from 2008 to 2012. The companies used samples are 23 companies which categorized as LQ-45 that exist from 2008 to 2012 or using Purposive Sampling Method.
Analysis of securitas consist of fundamental and technical analysis. In fundamental analysis and technical, analist often uses factors fundamental and technical. Fundamentalâ€™s and technicalâ€™s factors in Multi-factor Models uses to perform the portfolio with special characteristics. Multi-factor Models are improved from the concept of Arbitrage Pricing Theory (APT).
Fundamental factors are consisted Financial Ratio (ROA, DER, EPS, PBV) and macroeconomic (exchange rate, inflations, gdp); than technical factors (trading volume, market capitalization, and previous stock price). Those are independen variables which towards stock return using Panelâ€™s Data then make analysis using Multiple Regressions.
This research shows that partially, several fundamental factors (ROA, DER, and EPS) have not significant influence and positif are toward stock return. However, PBV have significant influence and negatif are toward stock return. Several macro economicâ€™s factors (kurs and GDP) have significant influence and positif are toward stock return, but inflation have significant influence at Î± = 10%. All of technicalâ€™s factors (trading volume, market capitalization, and previous stock price) have not significant influence and positif (market capitalization, and previous stock price), negatif (trading volume) are toward stock return.Simultaneously, fundamentalâ€™s factors, macro economic, and technicalâ€™s factors have significant influence and positif are toward stock return.
Managerial implication of this research are the investors can use fundamentals analysis with focus on PBV ratio, emiten must be more attention macro economic factors, especially exchange rate and GDP. Investors in Indonesia Stock Market more like fundamentalâ€™s analysis than technicalâ€™s analysis, but investor also can use integrated analysis by combine of fundamental and technicalâ€™s analysis.

Experimental effect of medium ratio on removal efficiency of nitrate nitrogen in groundwater by zero-valent iron, activated carbon and zeolite
Authors: Cao Sizhi , Liu Peigui , Liu Mingchao , Wang Gang , Li Zaili , Tong Yansong , Huang Zhiqiang 
Published: February 2019

Abstract
In this study, column experiments in the laboratory were set up to examine how the concentrations of nitrate nitrogen, nitrite nitrogen, and ammonia nitrogen changed when a nitrate-rich solution was passed through a medium comprising zero-valent iron, activated carbon, zeolite, and coarse sand. We varied the proportions of the components of the medium to determine how it influenced the nitrate removal and nitrogen fractions. Three different scenarios were used, with: (1) iron, activated carbon, and coarse sand at a ratio of 3:1:6; (2) iron, activated carbon, and zeolite at a ratio of 3:1:6; and (3) iron, activated carbon, and zeolite at a ratio of 3:3:4. The nitrate nitrogen concentration decreased from 25 mg/L to 2 mg/L in the first scenario. Removal was better when zeolite was added to the medium as most of the nitrate nitrogen broke down to ammonia nitrogen, with nitrite nitrogen as an intermediate product. The results of the tests showed that nitrate removal was best when the medium was iron, activated carbon, and zeolite, mixed at a ratio of 3:1:6. This study provides a scientific reference for in situ remediation of nitrate pollution in groundwater.
Perioperative Evaluation and Management of Patients With Portopulmonary Hypertension Aiming for Orthotopic Liver Transplantation
Authors: Díaz-Gómez José L. , Franco Pablo Moreno , Canabal Juan M. , Irefin Samuel , Burger Charles D. 
Published: February 2019

Background: Portopulmonary hypertension (POPH) is defined as pulmonary arterial hypertension (PAH) in the context of portal hypertension. Severe POPH has been considered an absolute contraindication of orthotopic liver transplantation (OLT).Objective: Since there are no definitive guidelines for the immediate preoperative, intraoperative, and postoperative evaluation and treatment of POPH patients, we have used published literature along with our experience to review current knowledge in this area.Summary: Moderate-to-severe POPH has important consequences in the perioperative management of candidates for OLT. Adequate right ventricular function is critical to survive the hemodynamic burden of OLT. Immediate preoperative assessment of hemodynamics; careful intraoperative monitoring and management of volume status, pressure changes, and ventricular function; and postoperative transitions of PAH-specific therapy are key components to successful OLT. We emphasize the advantages of the echocardiogram during all of these phases and stress the importance of a team approach to plan care and respond to the multiple challenges of OLT in POPH.
Overview of WHO Group 2 Pulmonary Hypertension Due to Left Heart Disease
Authors: Barnett Christopher F. , Selby Van N. 
Published: February 2019

Background: Left heart disease (LHD) is the most common cause of pulmonary hypertension (PH) and is associated with poor patient outcomes, especially among patients undergoing heart transplant evaluation.
Implications for clinicians: Left heart disease should be considered in all patients undergoing an evaluation for PH. Correct management of PH from LHD is to optimize treatment of LHD. Pulmonary vasodilators used to treat pulmonary arterial hypertension should not be used in patients with PH from LHD.
Conclusions: Additional research is needed to better understand how PH develops in patients with LHD and to investigate the role for treatment targeting PH in these patients.
The Genetic Variants of IKZF1 Gene Linked with the Growing Risk of Childhood Acute Lymphoblastic Leukaemia
Authors: Tayel Safaa I. , El-Hefnway Sally M. , Abo El-fotoh Wafaa Moustafa M. , El-Zayat Rania S. 
Published: February 2019

Background:
The zinc finger protein IKAROS (IKZF1) is an essential
transcription factor in haematopoiesis that is involved primarily in lymphoid tissue
differentiation. Many studies have indicated that IKZF1 alterations may be associated
with acute lymphoblastic leukaemia, but the results remain controversial.

Objective:
We aimed to investigate the association of the rs4132601 T/G and
rs10272724 T/C IKZF1 gene polymorphisms with the risk of childhood acute
lymphoblastic leukaemia and to determine whether these genetic variants affect the
clinical parameters and the iron profiles of these children cohort.

Methods:
This case control study was conducted on 170 Egyptian children comprising
of two groups: group (I) included 90 children diagnosed with acute lymphoblastic
leukaemia and group (II) comprised of 80 ages and sex-matched healthy control
children. The studied polymorphisms were genotyped using PCR restriction fragment
length polymorphism (PCR-RFLP).

Results:
A higher frequency of the mutant GG genotype and G allele of rs4132601 was
found in the patient group than in the control group. The results also showed a
significant difference among the rs10272724 genotypes, with a higher frequency of the
mutant CC genotype and C allele in the patients than in controls. The mutant GG
genotype of rs4132601 and the mutant CC genotype of rs10272724 were associated
with a higher serum ferritin level and transferrin saturation and an older age at diagnosis
of acute lymphoblastic leukaemia than the other genotypes.

Conclusion:
IKZF1 rs4132601 and rs10272724 could be considered significant risk
contributors to childhood acute lymphoblastic leukaemia and may impact the iron
profiles in these children.
