Published: July 2018

Handwriting is a skill that is a requirement for all individuals, however, there is a deep and decisive debate about whether or not the cursive handwriting is necessary in this era of technological innovations. While the necessity of compulsory cursive handwriting education is generally addressed by educators and politicians, there is no consensus on it, and the opinions of the people with interest or concern in education (e.g. teachers, students and parents) are not so often asked. For this reason, the aim of this study is to reveal the views of teachers, students and parents on the cursive handwriting education. 57 classroom teachers, 230 primary school fourth grade students and 14 parents participated in the study from four public primary schools in Ankara. Data were collected using ‘Personal Information Form’, ‘Cursive Handwriting Education Attitude Scale’, ‘Parent Questionnaire’ and ‘Student Questionnaire’. Quantitative data were analyzed using descriptive statistics techniques and qualitative data were analyzed by content analysis. According to the findings of the study, teachers and parents are not satisfied with the use of cursive handwriting. While teachers indicated that they would prefer print letters instruction if they had given a chance to choose. Parents affirmed that they could not give support to their children during their writing education. On the other hand, most of the students stated that they had difficulty in reading even their own handwritings, although most of them declared that they like to write with the cursive handwriting.

The purpose of the study was to present data on polymixin-based antibiotics with activity against infections caused by multidrug- resistant Gram-negative bacteria, such as Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa.Material and methods. The review includes data from clinical as well as in vitro studies for the period 1998–2017. The search for relevant sources was carried out in the Medline, Cochrane Library, Elibrary and other databases.Results. The analysis of the data showed the presence of synergism and additive activity of polymyxin in combination with carbapenems, rifampicin and azithromycin. However, experimental data showed no direct positive correlation between combination of polymyxim and azithromycin/ rifampicin. In clinical studies, in hospital-acquired pneumonia, including ventilator-associated pneumonia, the clinical response rate of polymyxin B combined with other antibiotics ranged from 38 % to 88 %. High nephro-and neurotoxicity of polymyxin observed in previous studies can be explained by a lack of understanding of its toxicodynamics or the use of an incorrect dose.Conclusion. Polymyxin B in combination with other antibiotics is a promising treatment against infectious complications caused by multidrug resistant Gram-negative bacteria.
Assessing runoff sensitivities to precipitation and temperature changes under global climate-change scenarios
Authors: Chen Lei , Chang Jianxia , Wang Yimin , Zhu Yuelu 
Published: July 2018

Abstract
An accurate grasp of the influence of precipitation and temperature changes on the variation in both the magnitude and temporal patterns of runoff is crucial to the prevention of floods and droughts. However, there is a general lack of understanding of the ways in which runoff sensitivities to precipitation and temperature changes are associated with the CMIP5 scenarios. This paper investigates the hydrological response to future climate change under CMIP5 RCP scenarios by using the Variable Infiltration Capacity (VIC) model and then quantitatively assesses runoff sensitivities to precipitation and temperature changes under different scenarios by using a set of simulations with the control variable method. The source region of the Yellow River (SRYR) is an ideal area to study this problem. The results demonstrated that the precipitation effect was the dominant element influencing runoff change (the degree of influence approaching 23%), followed by maximum temperature (approaching 12%). The weakest element was minimum temperature (approaching 3%), despite the fact that the increases in minimum temperature were higher than the increases in maximum temperature. The results also indicated that the degree of runoff sensitivity to precipitation and temperature changes was subject to changing external climatic conditions.

Published: July 2018

Abstract
Chemical oxygen demand (COD), an important indicative measure of the amount of oxidizable pollutants in wastewater, is often analyzed off-line due to the expensive sensor required for on-line analysis. However, its off-line analysis is time-consuming. An on-line COD estimation method was developed with photoelectrocatalytic (PEC) technology. Based on the on-line data of the oxidation–reduction potential (ORP), dissolved oxygen (DO) and pH of wastewater, four different artificial neural network methods were applied to develop working models for COD estimation. Six different batches of sequence batch reactor (SBR) effluent from a paper mill were treated with PEC oxidation for 90 minutes, and 546 data points were collected from the on-line measurements of ORP, DO and pH, and the off-line COD analysis. After having training and validation with 75% and 25% of data, and evaluation with four statistical criteria (R2, RMSE, MAE and MAPE), the estimation results indicated that the developed radial basis neural network (RBNN) model demonstrated the highest precision. Subsequently, the application of the RBNN model to a new batch of SBR effluent from the paper mill revealed that the RBNN model was acceptable for COD estimation during the PEC advanced treatment process of papermaking wastewater, which implied its possible application in the future.

preferable in comparison with the chemical and physicochemical methods. The review covers mainly
publications published in the last 20 years.
A Novel Adaptive PET/CT Image Fusion Algorithm
Authors: Xia Kai-jian , Wang Jian-qiang , Cai Jian 
Published: July 2018

Background:
Lung cancer is one of the common malignant tumors. The successful diagnosis
of lung cancer depends on the accuracy of the image obtained from medical imaging modalities.

Objective:
The fusion of CT and PET is combining the complimentary and redundant information
both images and can increase the ease of perception. Since the existing fusion method sare not perfect
enough, and the fusion effect remains to be improved, the paper proposes a novel method
called adaptive PET/CT fusion for lung cancer in Piella framework.

Methods:
This algorithm firstly adopted the DTCWT to decompose the PET and CT images into
different components, respectively. In accordance with the characteristics of low-frequency and
high-frequency components and the features of PET and CT image, 5 membership functions are
used as a combination method so as to determine the fusion weight for low-frequency components.
In order to fuse different high-frequency components, we select the energy difference of decomposition
coefficients as the match measure, and the local energy as the activity measure; in addition,
the decision factor is also determined for the high-frequency components.

Results:
The proposed method is compared with some of the pixel-level spatial domain image fusion
algorithms. The experimental results show that our proposed algorithm is feasible and effective.

Conclusion:
Our proposed algorithm can better retain and protrude the lesions edge information
and the texture information of lesions in the image fusion.

Authors: Caprili Silvia , Morelli Francesco , Salvatore Walter , Natali Agnese 
Published: July 2018

Background:
The lack of codified standards for the design of automated rack supported warehouses forced engineers to use personal experience and commonly accepted rules.

Objective:
This paper investigates the efficacy of applying Eurocodes’ rules for the design and analysis of automated rack supported warehouses. Structural performance, construction feasibility and economic effort are considered.

Method:
A typical case study building was designed following the two approaches proposed by Eurocodes: elastic and dissipative.

Results:
The satisfaction of the capacity design requirements, used for dissipative approach, was not always possible. Analyses showed the development of non-uniform collapse mechanisms and yielding patterns.

Conclusion:
Specific design rules and analysis techniques shall be developed accounting for the structural performance of automated rack supported warehouses.

Published: July 2018

Background:
A comparative analysis of Automatic Generation Control (AGC) of two-area
electric power systems interconnected by AC and AC-DC links under deregulated environment is
conducted. Each area has Thermal-Thermal (TT), Thermal-Hydro (TH) and/or Hydro-Hydro (HH)
multiple power sources. A maiden attempt is made to study the demeanour of HH power system under
restructured mode.

Methods:
The state space models of the power systems have been developed to simulate all market
transactions probable in a deregulated power environment and optimal proportional integral structured
controller is applied to improve the dynamic performance. The concept of DISCO participation matrix
is harnessed to simulate the transactions.

Results:
Eigenvalue analysis is carried out to assess the comparative stability analysis of the power
systems with/without AC-DC links. Further, the dynamic responses of TT, TH and HH power systems
are contrasted in the presence of AC link and AC-DC links. The inclusion of AC-DC links improves the
dynamic performance of all the systems remarkably, however, the responses of HH system are
sluggish/poor with large undershoots in comparison to TT and TH systems. Also, TH system exhibits
degraded dynamic performance compared to TT system.

Conclusion:
Moreover, optimal controller is found competent to demonstrate the matching of
generation with power demand under different market transactions.

Published: July 2018

The suitability of corn kernel as raw material to produce miso fermented by rice-koji containing Aspergillus oryzae and Rhizopus oligosporus has been investigated. The optimization was conducted on two important factors in miso production namely mold composition in rice-koji and salt concentration. The mold composition was prepared by inoculating the spores of 2% A. oryzae, 2% R. oligosporus, and 2% the mixture of both in a ratio of 1:1, 2:1, and 1:2 (v/v) into different rice media. The mold composition was optimized to produce rice-koji with high α-amylase and protease activity. Different NaCl concentrations of 10%, 15%, and 20% were subjected to optimization process and added to each mixture after five days of fermentation. The salt concentration was also optimized to produce corn kernel miso with high glucose and high dissolved protein concentration. The result showed that rice-koji containing A. oryzae and R. oligosporus in the ratio of 1:1 had the highest α-amylase and protease activity of 0.42 U/mL and 0.45 U/mL respectively. In addition, the presence of 10% NaCl in corn kernel miso fermented by A. oryzae and R. oligosporus in the ratio of 1:1 exhibited the highest glucose and dissolved protein concentration of 0.64 mg/mL and 8.80 mg/mL respectively. The optimized corn kernel miso by A. oryzae and R. oligosporus in the ratio of 1:1 with 10% NaCl was subjected to nutrient content analysis and compared to the result before the corn kernel was fermented. The nutrient content analysis showed nutrient enhancement after corn kernel was fermented and transformed into a miso. Glucose, dissolved protein, and fat content increased 6.74, 1.34, 7.63 times respectively. This study concludes corn kernel could be utilized to produce a novel corn kernel miso for dietary diversification and for improving nutritional and health status.

Published: July 2018

Background and objectives
Ambulatory BP is increasingly recognized as a better measure of the risk for adverse outcomes related to hypertension, an important comorbidity in patients with CKD. Varying definitions of white-coat and masked hypertension have made it difficult to evaluate differences in prevalence of these BP patterns across CKD cohorts.

Design, setting, participants, & measurements
The International Database of Ambulatory BP in Renal Patients collaborative group established a large database of demographic, clinical, and ambulatory BP data from patients with CKD from cohorts in Italy, Spain, the Chronic Renal Insufficiency Cohort (CRIC) and the African American Study of Kidney Disease and Hypertension Cohort Study (AASK) in the United States, and the CKD Japan Cohort (CKD-JAC). Participants (n=7518) with CKD were included in the present analyses. Cutoffs for defining controlled BP were 140/90 mm Hg for clinic and 130/80 mm Hg for 24-hour ambulatory BP.

Results
Among those with controlled clinic BP, compared with CKD-JAC, AASK participants were more likely to have masked hypertension (prevalence ratio [PR], 1.21; 95% confidence interval [95% CI], 1.04 to 1.41) whereas CRIC (PR, 0.82; 0.72 to 0.94), Italian (PR, 0.73; 0.56 to 0.95), and Spanish participants (PR, 0.75; 0.64 to 0.88) were less likely. Among those with elevated clinic BP, AASK participants were more likely to have sustained hypertension (PR, 1.22; 95% CI, 1.13 to 1.32) whereas Italian (PR, 0.78; 0.70 to 0.87) and Spanish participants (PR, 0.89; 0.82 to 0.96) were less likely, although CRIC participants had similar prevalence as CKD-JAC. Prevalence of masked and sustained hypertension was elevated in males, patients with diabetes, participants on four or more antihypertensives, and those with moderate-to-severe proteinuria.

Conclusions
In a large, multinational database, the prevalence of masked and sustained hypertension varied across cohorts independent of important comorbidities.

Published: July 2018

En este trabajo investigamos la presencia, diversidad y relaciones filogenéticas de genes asociados a la tolerancia al arsénico (As) en 37 cepas del género Bacillus, aisladas de tapetes microbianos localizados en pozas termales en Araró, Michoacán, México. Se diseñaron oligonucleótidos específicos para la amplificación por PCR de los genes arsB (bomba de expulsión de arsenito) y arsC (arsenato reductasa), ACR3 (transportador de arsenito) y aoxB (arsenito oxidasa) del género Bacillus, detectando únicamente los genes arsB y arsC en 21 de las 37 cepas analizadas (56.7% del total). Los análisis tipo Blastx demuestran una alta identidad (84-100%) con bombas de expulsión de arsenito (ArsB) y proteínas arsenato reductasas (ArsC) de diversas cepas de los géneros Bacillus, Paenibacillus, Psychrobacter y Planococcus. Dichos análisis se confirmaron a través de la construcción de filogenias de los genes arsB y arsC. La detección de los genes arsB y arsC en cepas de Bacillus se correlacionó con valores de hipertolerancia al As, los cuales correspondieron a 32 y 128 mM de arsenito (III) y arsenato (V), respectivamente. Finalmente, los genes arsB y arsC identificados en cepas de Bacillus podrían ser un mecanismo de resistencia al arsénico en un ambiente acuático extremo, como las pozas termales de Araró.
