The Guide Dog as a Mobility Aid Part 1: Perceived Effectiveness on Travel Performance
Authors: Lloyd Janice K.F. , La Grow Steven , Stafford Kevin J. , Budge R. Claire 
Published: May 2018

Abstract

This is the first of a two-part study that examined the effects of a guide dog as an aid to mobility; both parts are published in this issue of the IJOM. The first part demonstrates the perceived effectiveness of the dog on travel performance, and the second part describes changes to travel habits, as well as advantages and disadvantages of guide dog mobility. In this first part of the study, the travel performance of 50 people who were blind or vision impaired was investigated retrospectively when participants used (a) mobility aids other than a guide dog (i.e., before a dog was acquired) and where applicable, a dog they considered to be (b) a satisfactory and (c) an unsatisfactory mobility aid. Results indicated that travel performance was considered significantly better when using a satisfactory dog compared to pre-guide dog mobility or an unsatisfactory dog. Follow-up tests were conducted to determine whether differences in travel ability before a dog was acquired affected travel performance when using a satisfactory dog. Participants were separated into three groups (poor, moderate and good travellers) based on their perceived travel ability pre-dog. Significant differences in travel performance were found between all three groups before a dog was used, but no differences were seen between the groups when using a satisfactory dog. Further tests indicated that travel performance was significantly better for all three levels of traveller when using a satisfactory dog compared to pre-dog mobility, with less accomplished travellers showing the greatest gains. The use of a dog also appeared to alleviate restrictions to travel caused by some non-visual conditions.
The Missing Link: A Collaborative Approach to Early Childhood Orientation and Mobility
Authors: Wells Kylie 
Published: May 2018

Abstract

The current role of the Orientation & Mobility (O&M) instructor routinely involves working with young children (birth to 6 years). The inclusion of this population to the caseload of O&M instructors brings with it unique challenges. Young children’s primary means of learning comes in the form of play, yet O&M traditionally tends to focus on skill specific instruction. For young children who are blind or vision impaired the ability to move out into space independently and with confidence will impact greatly on their learning experiences. This paper will examine the need to embrace a collaborative approach when working in early childhood O&M, with an emphasis on the significance of O&M instructors working with paediatric physiotherapists.
Early Intervention Orientation and Mobility: A Western Australian Perspective
Authors: Scott Bronwen 
Published: May 2018

Abstract

Early intervention Orientation & Mobility (O&M) training is a key component of the Western Australian Department of Education’s Vision Education Service. Children who are blind or have vision impairments are introduced to O&M skills, including the long cane, as soon as they are able to walk. A description of the service is provided, with some basic concepts and ideas for O&M specialists working with very young children. A key factor in the success of this program is collaboration between professionals, and allowing children to take control over their own mobility.

Optimal allocation of nonpoint source pollution control measures using two modern comprehensive evaluation methods
Authors: Wu Lei , Tang Xiaodan , Ma Xiaoyi 
Published: May 2018

AbstractNonpoint source (NPS) pollution has been studied for many years but it exhibits random, widespread, complex uncertainties which make it difficult to manage and control. We employ group decision-making utilizing the fuzzy comprehensive evaluation method (FCE) and the analytic hierarchy process method (AHP) and comparatively evaluate the optimal allocation of NPS pollution control measures. Here, we present the top-three evaluation results ranked as follows: combination of contour tillage and vegetative filter strips (CT & VFS), vegetative filter strips (VFS), and combination of contour tillage and fertilizer reduction and vegetative filter strips (CT & FR & VFS). The fourth, fifth and sixth results by FCE method are chemical fertilizer reduction (FR), returning farmland to forest or pasture (RF), and combination of contour tillage and fertilizer reduction (CT & FR), while the corresponding results by AHP method are returning farmland to forest or pasture (RF), combination of contour tillage and fertilizer reduction (CT & FR), and fertilizer reduction (FR). The seventh results for each of the two methods are contour tillage (CT), which has a positive but limited effect on nutrient loss reduction. Our results provide new underlying insights needed to guide the resonable allocation of NPS pollution control measures.
Effectiveness of methods for selecting pumps as turbines to operate in water distribution networks
Authors: Marchiori Isabela Niedo , Lima Gustavo Meirelles , Brentan Bruno Melo , Junior Edevar Luvizotto 
Published: May 2018

Abstract
Pressure control is an important feature for reducing leakages in water supply systems, and the use of pressure reducing valves has been well established as an efficient option for this purpose. However, several studies have demonstrated that the energy available on such sites could be used to generate electrical energy, instead of being dissipated as head loss; therefore, a more efficient and sustainable solution could be applied for pressure control. Due to the low amount of power available, the use of pumps as turbines (PATs) is highly recommended. However, manufacturers do not provide pump curves operating as turbines, making PAT selection challenging. Different empirical methods can be found in the literature for estimating PAT performance based on the pump operating conditions. Thus, this paper presents a comparative analysis of nine different methods, using real data from 14 pumps. Furthermore, the effectiveness of these methods for PAT selection is evaluated in a hypothetical network.
Development and Validation of a Robust QSAR Model for Benzothiazole Hydrazone Derivatives as Bcl-XL Inhibitors
Authors: Gupta Pawan , Gutcaits Aleksandrs 
Published: May 2018

Background:
B-cell Lymphoma Extra Large (Bcl-XL) belongs to B-cell Lymphoma two
(Bcl-2) family. Due to its over-expression and anti-apoptotic role in many cancers, it has been proven
to be a more biologically relevant therapeutic target in anti-cancer therapy. In this study, a Quantitative
Structure Activity Relationship (QSAR) modeling was performed to establish the link between
structural properties and inhibitory potency of benzothiazole hydrazone derivatives against Bcl-XL.

Methods:
The 53 benzothiazole hydrazone derivatives have been used for model development using
genetic algorithm and multiple linear regression methods. The data set is divided into training and
test set using Kennard-Stone based algorithm. The best QSAR model has been selected with statistically
significant r2 = 0.931, F-test =55.488 RMSE = 0.441 and Q2 0.900.

Results:
The model has been tested successfully for external validation (r2
pred = 0.752), as well as
different criteria for acceptable model predictability. Furthermore, analysis of the applicability domain
has been carried out to evaluate the prediction reliability of external set molecules. The developed
QSAR model has revealed that nThiazoles, nROH, EEig13d, WA, BEHv6, HATS6m,
RDF035u and IC4 descriptors are important physico-chemical properties for determining the inhibitory
activity of these molecules.

Conclusion:
The developed QSAR model is stable for this chemical series, indicating that test set
molecules represent the training dataset. The model is statistically reliable with good predictability.
The obtained descriptors reflect important structural features required for activity against Bcl-XL.
These properties are designated by topology, shape, size, geometry, substitution information of the
molecules (nThiazoles and nROH) and electronic properties. In a nutshell, these characteristics can
be successfully utilized for designing and screening of novel inhibitors.
Investigation on the Stability of New Biologically Active Thiosemicarbazone- Derived Compounds by a Validated HPLC-PDA Method
Authors: Secci Daniela , Locatelli Marcello , Kabir Abuzar , Salvatorelli Erika , Macedonio Giorgia , Mollica Adriano , Carradori Simone 
Published: May 2018

Background:
New Chemical Entities (NCEs) could be generally exposed to several stress
conditions of hydrolysis, oxidation, photolysis and thermal degradation in order to better characterize
the compounds and to know if the degradation processes lead to generate undesired (or toxic) products.

Objective:
This paper reports the development and validation of an HPLC-PDA method for the qualiquantitative
profiles determination and chemical-physical stability evaluation after forced decomposition
studies of thiosemicarbazone-derived compounds endowed with interesting pharmacological activities.

Methods:
All compounds and two possible degradation products were resolved by using a Grace® C-18
(ODS) column (250 mm × 4.6 mm; 5 mm particle size) in gradient elution mode. The chromatographic
analysis was run in 28 min. The analytical method was correctly validated using weighted-matrix
matched standard curves in the following ranges: 1-100 µg mL-1 for the lead compounds, and 0.1-8 μg
mL-1 for the two possible degradation products showing a good correlation coefficients (≥0.9756). Precision
and trueness comply with International Guidelines on method validation.

Results:
The obtained results demonstrated an excellent stability of the thiosemicarbazone-derived
products following the treatment with UV set at 254 nm and heat (at 80°C). In solution, however, the
compounds showed different stability profiles.

Conclusion:
The results obtained through the forced degradation studies provided important information
not only for handling, formulation and storage of the substances, but also for the possible chemical
changes in order to increase the stability. Given the importance of the non-conventional dosage
forms, the stability of the substances was also analyzed in the presence of widely used surfactants.
Quantitative Determination of Topiramate in Human Serum and Umbilical Cord Blood
Authors: Cifuentes Cristina , Mennickent Sigrid , De Diego Marta 
Published: May 2018

Background:Topiramate (TPM), an anticonvulsant drug, was determined in human serum and in umbilical cord blood. TPM can produce severe damage to the fetus (baby into mother´s uterus), and it is not always possible that epileptic women change their drug during pregnancy, because some antiepileptic drugs are not effective on some people. Using pregnant-mother serum blood, we can estimate drug levels in fetus serum, and by umbilical cord blood, is possible estimate drug levels in serum babies, without the ethic aspects to withdrawal blood of them.Methods:Quantitation was achieved by LC/DAD, using liquid-liquid extraction for isolation of TPM from both biological fluids, using dichloromethane as extraction solvent, and dabsyl chloride as derivatizing agent.Results:The method was linear over the concentration range of 5.0 to 20.0 µg/mL for TPM in human serum, and between 1.6-50.0 µg/mL for TPM in umbilical cord blood (r=0.999 and r= 0.998, respectively). RSD, for intra-assay study, was between 0.64%- 1.22% (n=3), and between 0.57% -1.86% (n=9) for inter-assay, when the biological fluid was human serum, and between 0.33% - 3.44%, and 3.38% -3.73%, respectively, when the matrix was umbilical cord blood. LOD was 0.40 µg/mL and 0.39 μg/mL for TPM in human serum and in umbilical cord, respectively, whereas LOQ was 1.20 µg/mL and 1.18 μg/mL, in each biological fluid. Recovery percentage for the accuracy study was between 94.0% and 109.8% (RSD ≤0.191).Conclusion:The method is precise, accurate, reproducible and selective for level analysis of TPM in both matrices.
