Published: February 2018

Abstract
Water is important resource for human survival and development. Coal mine wastewater (CMW) is a byproduct of the process of coal mining, which is about 7.0 × 1010 m3 in China in 2016. Considering coal mine wastewater includes different ingredients, a new bubble column humidification and dehumidification system is proposed for CMW treatment. The system is mainly composed of a bubble column humidification and dehumidification unit, solar collector, fan and water tank, in which air is used as a circulating medium. The system can avoid water treatment component blocking for reverse osmosis (RO) and multi effect distillation (MED) dealing with CMW, and produce water greenly. By analysis of heat and mass transfer, the effects of solar radiation, air bubble velocity and mine water temperature on water treatment production characteristics are studied. Compared with other methods, thermal energy consumption (TEC) of bubble column humidification and dehumidification (BCHD) is moderate, which is about 700 kJ/kg (powered by solar energy). The results would provide a new method for CMW treatment and insights into the efficient coal wastewater treatment, besides, it helps to identify the parameters for the technology development in mine water treatment.

Authors: Anushiravani Majid , Manteghi Ali A. , Taghipur Ali , Eslami Mahdi 
Published: February 2018

Background:
According to new studies, only 60% of depressed patients respond to pharmaceutical
treatment while suffering from their side effects. Natural products as adjuvant or alternative
therapies should be examined to find safer and more effective ways to cope with depression.

Objective:
To find out the potential benefits of a combined herbal drug based on Echium amoenum
compared with citalopram in the treatment of Major Depressive Disorder.
Design and Setting: In psychiatry clinics of Mashhad University of Medical Sciences, 50 patients who
met the criteria for Major Depressive Disorder based on DSM-5 were studied in a parallel randomized
controlled trial.

Design and Setting:
In psychiatry clinics of Mashhad University of Medical Sciences, 50 patients who
met the criteria for Major Depressive Disorder based on DSM-5 were studied in a parallel randomized
controlled trial.

Intervention:
Subjects were randomly assigned to receive Echium amoenum compound syrup (EACS)
or citalopram tablet for 8 weeks.

Outcome Measures:
The efficacy of treatments and recurrence of disease were surveyed and compared
according to Hamilton depression rating scale at weeks 0, 4, 8, 12.

Results:
Patients in both groups of citalopram and EACS showed remarkable reduction in scores of
Hamilton questionnaire. At the eighth week of treatment, the mean scores in EACS group were significantly
lower than citalopram group (p-value = 0.03). 52% of patients suffered from various complications
in citalopram group while just 12% of patients in EACS group reported few complications.

Conclusion:
Clinical efficacy of this herbal drug was significantly higher than citalopram, and complications
were also less and lower in EACS group. Further studies with larger groups and para-clinical assessments
such as serologic tests and QEEG would improve our understanding of the impacts and mechanisms
of EACS.
Combinatorial Use of DNA Ligase Inhibitor L189 and Temozolomide Potentiates Cell Growth Arrest in HeLa
Authors: Jahagirdar Devashree , Purohit Shruti , Sharma Nilesh K. 
Published: February 2018

Introduction:The issues of carcinoma drug resistance to alkylating agents such as Temozolomide (TMZ) are considered as a major concern in therapeutics. The potential ways to achieve better cancer cell growth arrest and cytotoxicity have been suggested including the combinatorial use of DNA repair protein inhibitors and genotoxic drug TMZ. Here, authors assess the ability of DNA ligase inhibitor (L189) to modulate TMZ mediated HeLa cell growth arrest and cytotoxicity.Materials and Methods:Here, authors have employed Trypan blue dye exclusion and propidium iodide (PI) using FACS to determine HeLa cell viability after exposure to TMZ with or without L189 inhibitor. Additionally, authors show the DNA ligase III protein level using ELISA and fluorescent microscopy to support the observed effects of combinatorial use of TMZ and L189.Results:In this paper, data indicate that the addition of L189 produced appreciable decrease in the growth of HeLa cells. However, combined treatment of L189 and TMZ showed enhanced TMZinduced HeLa growth arrest possibly in G2/M cell cycle phase without employing cell death mechanisms.Conclusions:These results underscore the combinatorial treatment using TMZ and L189 to bring desirable cancer cell growth arrest and future molecular study to dissect out the participating pathways.

Authors: Tripathi Shashank , Jain Devesh R. , Sharma Himanshu D. 
Published: February 2018

Introduction:In this paper, authors present the development of a completely automated system to perform 3D micromanipulation and microassembly tasks. The microassembly workstation consists of a 3 degree-of-freedom (DOF) MM3A® micromanipulator arm attached to a microgripper, two 2 DOF PI® linear micromotion stages, one optical microscope coupled with a CCD image sensor, and two CMOS cameras for coarse vision.Methods:The whole control strategy is subdivided into sequential vision based routines: manipulator detection and coarse alignment, autofocus and fine alignment of microgripper, target object detection, and performing the required assembly tasks. A section comparing various objective functions useful in the autofocusing regime is included.Results:The control system is built entirely in the image frame, eliminating the need for system calibration, hence improving speed of operation. A micromanipulation experiment performing pick-and-place of a micromesh is illustrated.Conclusion:This demonstrates a three-fold reduction in setup and run time for fundamental micromanipulation tasks, as compared to manual operation. Accuracy, repeatability and reliability of the programmed system is analyzed.

Reflexões sobre a família de indivíduos negros e os desafios do seu quotidiano
Authors: Araujo Lucimeire Carvalho , Camargo Climene Laura 
Published: February 2018

Esta reflexão teórica busca apresentar elementos que aponte como se organizou a família de indivíduos negros ao longo dos anos e os desafios que viveram e vivem no quotidiano atual. A família do indivíduo negro teve sua identidade destituída ou mesmo arrancada, pela violência sócio-histórica sofrida desde a escravatura até os dias de hoje, fato que contribui para que enquanto instituição formadora da identidade social, étnica e cultural de seus membros propague através das relações familiares e sociais o que aprendeu e viveu. Diante destas considerações, podemos entender que na prática quotidiana, faz parte da vida de indivíduos negros, a violência e o racismo que são passados de geração em geração como uma espécie de herança que contribui para o ciclo de exclusão.

The Role of Organizational Social Capital in the Design of Management Control Systems
Authors: Ströbele Alexander , Wentges Paul 
Published: February 2018

ABSTRACT
Interest in so-called “soft controls,” such as clan control, and what role they may play in designing management control systems has been growing in recent years. In particular, the conditions under which clan control and formal bureaucratic controls complement or substitute each other are the subject of an ongoing debate. The aim of this paper is to investigate the role of organizational social capital in the design of management control systems and, more specifically, to better understand the functioning of clan control. We argue that adopting a social capital perspective can help explain how clan control works and what positive effects it has on performance: organizational social capital moderates the positive effect of clan control on performance and enables organizations to use clan control and bureaucratic controls complementarily. We provide empirical evidence that supports our hypotheses and is based on survey data from 523 small and medium-sized enterprises in Germany.
reflejo de la historia a través de José María Merino
Authors: Abad Lavín Soledad 
Published: February 2018

Una de las facetas que definen parte de la obra narrativa de José María Merino (La Coruña, 1941) es la aparición de elementos históricos como vertebradores de la trama. En algunos de los casos estos elementos se exponen en pequeñas pinceladas, sin embargo, en otros, constituyen el elemento central de la narración, pudiendo clasificar dichas obras bajo la etiqueta de “novelas históricas”.
En este trabajo nos proponemos profundizar en algunos de estos títulos —Las visiones de Lucrecia (1996), El heredero (2003), La sima (2009), Musa Décima (2016)— para apreciar las diferencias en la disposición que el autor hace de la Historia y el papel que la misma cumple como elemento narrativo.
El lápiz del carpintero: la voz de los silenciados
Authors: Bazán Rodríguez Óscar 
Published: February 2018

Desde la teoría postcolonial, se analiza la obra de Manuel Rivas, El Lápiz del Carpintero, con especial atención al vínculo que se establece entre el guardia de prisión Herbal y el prisionero Da Barca, relación análoga a la que se da entre colonizador y colonizado, según las ideas de Cesáire o Fernando Ortiz entre otros. Asimismo, siguiendo las teorías de Kristeva y de Spivak acerca del “extraño” y del “subalterno”, se completa una imagen reivindicativa a través de la cual las voces de los que han sido silenciados en la realidad de la guerra civil se recuperan en la ficción, con ese lápiz que habla al carcelero, y que le sirve de conciencia.

Authors: Hopper Kate , Garcia Rojas Alejandro , Barter Linda 
Published: February 2018

Abstract
OBJECTIVE To determine common fluid therapy practices of small animal practitioners and identify fluid therapy-related knowledge gaps that may benefit from improved educational efforts, targeted research, or both.
DESIGN Online survey.
SAMPLE 1,496 small animal veterinarians
PROCEDURES An online survey was provided to members of the Veterinary Information Network between December 23, 2013, and January 30, 2014. The survey consisted of 24 questions investigating the administration of crystalloid and synthetic colloid solutions, but not blood products, and focused primarily on the choice of fluid type, frequency of administration, type of patient treated with fluids, treatment with fluids subcutaneously versus IV, and potassium supplementation of fluids. Only responses from practicing small animal veterinarians were included. Not all respondents answered every question, and some questions allowed > 1 answer.
RESULTS Balanced crystalloid solutions were the most common fluid type in all clinical scenarios described. The most common maintenance IV fluid rate reported by respondents (762/1,333 [57%]) was 60 mL/kg/d (27 mL/lb/d); calculation of fluid administration rate by means of body surface area was infrequent. Challenges of fluid therapy included determining the appropriate rate (572/1,496 [38%]) and fluid type (497/1,496 [33%]) and determining the need for potassium supplementation (229/1,496 [15%]).
CONCLUSIONS AND CLINICAL RELEVANCE Small animal veterinarians tended to favor isotonic balanced crystalloid solutions for IV fluid therapy, compared with other common choices such as isotonic saline (0.9% NaCl) solution. Despite its ubiquity, respondents found many aspects of fluid therapy to be challenging, suggesting the need for easy to use, evidence-based guidelines.

Published: February 2018

Background: The association between longitudinal changes in serum glucose level and longitudinal changes in [18F] Fluorodeoxyglucose-PET (FDG PET) measurements of Alzheimer’s disease (AD) risk are unknown. Objective: To investigate whether variation in serum glucose levels across time are associated with changes in FDG PET measurements of cerebral metabolic rate for glucose (rCMRgl) in brain regions preferentially affected by Alzheimer’s disease (AD). Methods: Participants are a subset of a prospective cohort study investigating FDG PET, apolipoprotein E (APOE) ɛ4, and risk for AD which includes data from baseline, interim, and follow up visits over 4.4±1.0-years. An automated brain-mapping algorithm was utilized to characterize and compare associations between longitudinal changes in serum glucose levels and longitudinal changes in rCMRgl. Results: This study included 80 adults aged 61.5±5 years, including 38 carriers and 42 non-carriers of the APOE ɛ4 allele. Longitudinal increases in serum glucose levels were associated with longitudinal CMRgl decline in the vicinity of parietotemporal, precuneus/posterior cingulate, and prefrontal brain regions preferentially affected by AD ( p < 0.05, corrected for multiple comparisons). Findings remained significant when controlled for APOE ɛ4 status and baseline and advancing age. Conclusions: Additional studies are needed to clarify and confirm the relationship between longitudinal changes in peripheral glucose and FDG PET measurements of AD risk. Future findings will set the stage on the use of FDG PET in the evaluation of possible interventions that target risk factors for the development of AD.

Background: Several modifiable lifestyle factors have been shown to have potential beneficial effects in slowing cognitive decline. Two such factors that may affect cognitive performance and slow the progression of memory loss into dementia in older adults are cognitive training and physical activity. There are currently no effective treatments for dementia; therefore, preventative strategies to delay or prevent the onset of dementia are of critical importance. Objective: The aim of this study was to determine the relative effectiveness of simultaneous performance of memory training and aerobic exercise to a sequential performance intervention on memory functioning in older adults. Methods: 55 older adults (aged 60– 75) with subjective memory impairments (non-demented and non-MCI) completed the intervention that consisted of 90-minute small group classes held twice weekly. Participants were randomized to either 4-weeks of supervised strategy-based memory training done simultaneously while stationary cycling (SIM) or sequentially after the stationary cycling (SEQ). Standardized neurocognitive measures of memory, executive functioning, speed of processing, attention, and cognitive flexibility were assessed at baseline and post-intervention. Results: The SIM group, but not the SEQ group, had a significant improvement on composite memory following the intervention (t(51) = 2.7, p = 0.01, effect size (ES) = 0.42) and transfer to non-trained reasoning abilities (t(51) = 6.0, ES = 0.49) and complex attention (t(51) = 3.1, p = 0.003, ES = 0.70). Conversely, the SEQ group, but not the SIM, showed significant improvement in executive functioning (t(51) = 5.0, p = 0.0001, ES = 0.96). Conclusion: These findings indicate that a 4-week simultaneous memory training and aerobic exercise program is sufficient to improve memory, attention, and reasoning abilities in older adults.
