The effect of human umbilical cord-derived mesenchymal stem cell conditioned medium on the peripheral nerve regeneration of injured rats

Peripheral nerve injury occurs in 3-10% of extremity trauma patients. Mesenchymal stem cells (MSCs) have been used in injuries. Nevertheless, the mechanism of human umbilical cord MSCs (UC-MSCs) and/or their conditioned medium (CM) capacity in regenerating peripheral nerves is not widely known. This study is aimed to determine the mechanism, of UC-MSC CM in improving the structure and function of the nerves after peripheral nerve injury. This experimental study used Sprague-Dawley rats. The experimental animals were divided into 3 groups: control (Sham [SH]), and treatment groups (standard therapy [ST] and CM). The sciatic nerve of the SH group was not injured (only exposed and closed), while those of the ST and CM groups were both cut and given standard sutures. The CM group was treated with topical UC-MSCs CM. The study was divided into two stages i.e. a short-term and long-term research to check the parameters at 7 and 70 days post injury (dPI), respectively. The parameters collected were motor functions (walking analysis), electrophysiology and structural parameters. There were signs of nerve injury in all rats on 3 dPI. CM group showed faster recovery on 14 dPI compared with the ST group that only showed improvement after the 28th dPI. Electrophysiological images showed better electrical conduction in CM than ST group, while histological features showed higher S100 marker was expressed in CM compared with ST, as well as SH group on 7 and 70 dPI. Overall, UC-MSC CM affected peripheral nerve regeneration after 14 dPI.
Stock and Corporate Bond Selection using Text

This thesis finds that the text in annual and quarterly reports of U.S. listed companies is related to the cross-section of average stock and corporate bond price volatility and returns even after controlling for other known risk factors. This effect can be attributed to underreaction due to limited attention of analysts and investors. We show that the underreaction to the text in these reports can systematically be exploited. An investment strategy that buys stocks or bonds of companies with few changes compared to previous reports (‘non changers’) and sells companies with many changes (‘changers’) over the period 1997-2017 earns significant alpha in the equity market, and high yield and investment grade corporate bond markets.
Geochemical Soil Survey for Au Exploration in the Uluwai Village in Toraja, South Sulawesi

A Geochemical soil survey was carried out over an area of approximately 25 km2 in Uluwai Village, Toraja Regency, South Sulawesi in order to select the promising areas for gold occurrences. The survey area is situated in the southern part of Toraja near the border with Enrekang Regency, about 340 km north of Makassar, the capital of South Sulawesi Province. The survey area is underlain within the Latimojong Complex, composed of metasedimentary sequence (upper Cretaceous) surrounded by Tertiary sedimentary rocks (Eocene to Miocene) of Toraja and Makale Formation. During the detailed survey, a total of 40 soil samples were taken using the grid pattern of 100 m by 50m. All samples were analyzed for Au, Ag, As and other metals (Cu, Zn, Bi, Co, Mo, Pb and U) using Atomic Absorption Spectrometer method after aqua regia digestion. The result shows that three Au and As anomalous sample were detected and the areas show similar directional patterns with the NW direction of the main regional fractures. From the detailed soil survey, two Au anomalous areas were finally proposed as promising prospects for the next Au exploration stage (geophysical investigation and drilling process).
New collision detection method for simulating virtual plant populations

Detecting and resolving the collision of organs between different plants or the collision of different organs of a single plant are key issues in the realistic construction of a virtual plant population. A suitable collision detection scheme is necessary to prevent a reduction in realism caused by organ penetration. A mixed bounding volume tree construction scheme based on the growth characteristics of tomato plants is proposed in this paper, and the construction mode of the bounding at all levels is simplified by using a digital tomato model. Using a parallel GPU approach, we designed a tomato plant population collision detection program with CUDA acceleration. The proposed method reduces the total collision detection time by 92%-96%.

Building Print Newspaper Customer Loyalty

Companies engaged in the industry of Newspapers in Jakarta are faced with the problems of maintaining and increasing customer loyalty. In strategic marketing, failure to maintain and increase customer loyalty greatly interferes with the performance of the company. This is reasonable because customer loyalty is an important component of corporate performance. If this happens, then the company will have difficulties in maintaining and developing the internal resources and advantages. Companies that are not able to maintain and develop the internal resources and advantages are threatened with bankruptcy because it will have implications on their revenue. The purpose of this study was to determine the customer relationship with Print Newspaper, identify the Newspaper Print product attributes, determine therelationship and the effect of customer and product attributes to the Print newspaper’s customer value, determine the effects of the relationship between customer and product attributes on the customer’s loyalty to Print Newspaper and determine the effects of customer value on customer loyalty Print Newspaper. The method used is descriptive, and the survey method of explanatory survey was used, with a sample size of 70 customers of the Print Newspaper in South Jakarta as the unit of analysis. The time horizon in this study was cross-sectional. Findings from this research are that their relationship program performance influences both customer and product attributes on customer value and customer loyalty, but customer relationship dominantly influences customer value, while the dominant product attributes influences customer loyalty.
The occurrence of liquefaction at low acceleration level

In common opinion, only medium-large earthquakes i.e., those that induce peak accelerations at the ground surface equal or larger than 0.15g are able to trigger liquefaction if susceptible soils are present. In an attempt to identify the minimum acceleration level capable to activate liquefaction phenomenon at a given site, the background data used to create some common verification charts were analysed with statistical tools. This allows detecting an acceleration threshold for the occurrence of liquefaction at around 0.1 g, value that might eventually be employed for codes and recommendations. In the light of the above considerations, in this paper, first the minimum acceleration causing pore pressure development on element tests is presented. Thereafter, a series of published case-histories of liquefaction occurrence at very low acceleration level are recalled and collected, together with new cases induced by recent earthquakes. It is then concluded that in young loose sandy deposits liquefaction might activated for peak acceleration around 0.1 g and, in some specific sites, even for lower acceleration level.

Where do New Zealand Female Engineers come from? Insights from a quantitative analysis

CONTEXT Females are under-represented in the New Zealand engineering student cohort. Increased female engagement in engineering subjects is a target of many tertiary education providers. The lack of diversity in engineering graduates has ramifications for engineering industry and limits productivity. It also contradicts the Critical theory, which promotes equity of opportunity across different people groups.

BEARD, HAIR, AND MUSTACHE: CONSUMPTION AND MASCULINITIES IN BARBERSHOPS

Men have been questioning gender stereotypes that establish what they should or should not consume. One example is the increase in the offer of services for the audience at new barbershops. This study aims to analyze how masculinities are constructed, administrated, and negotiated in barbershops. Participant observations were conducted in barbershops as the method and 17 consumers and market agents were interviewed. The study’s findings suggest that the symbolic meanings of what it is to be masculine emerge in a dialectic process among consumers, market agents, and barbershops. These symbolic meanings are used to actively build and negotiate their masculinities. This process takes place in three ways: i) differentiation from the female world; ii) a space for relaxation and wellbeing; and iii) a space for men to socialize. The study also presents the academic and managerial implications of the findings.
A THESIS SUBMITTED TO THE FACULTY OF THE GRADUATE SCHOOL OF THE UNIVERSITY OF MINNESOTA BY Prakash Palamedu Sundaram IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN ELECTRICAL ENGINEERING

Voltage references are broadly used in analog and digital systems to generate a DC voltage independent of process, supply voltage and temperature (PVT) variations. Conventional band gap references (BGR) add the forward bias voltage across a PN junction with a voltage that is proportional to absolute temperature to produce an output that is insensitive to changes in temperature. BGRs generate a nearly temperature independent reference, of about 1.25 V, and therefore they require a higher supply voltage, which might not meet the low voltage constraints for low-power applications such as passive RFID’s, wearable and implantable medical devices. Also, BGRs use resistors that need more area on silicon. One possible solution to meet the low power requirement is to operate MOSFETs in subthreshold region. Most often, forward biased PN-junctions of BGRs are substituted with MOSFETs biased in the subthreshold region and achieves a supply voltage down to 0.6 V. This paper presents a sub-1V voltage reference circuit that has only MOS transistors, all working in subthreshold region with a supply voltage down to 0.45 V and a supply current of 1nA at room temperature for ultra-low power applications. The circuit is designed and simulated in 0.13um technology.
Lessons Learned from Facilitating a Pre-Service Teacher/Youth Mentoring Program

Traditional adult/youth mentoring programs have been associated with a host of positive academic, behavioral, and social/emotional youth outcomes. Little research, however, has been done on pre-service teacher/ youth mentoring programs; specifically if the benefits associated with more traditional mentoring programs translate into this context. For teacher educators, what is most promising about such mentoring programs is the potential for a mutually beneficial mentoring relationship. Pre-service teachers need experience working with youth as badly as youth need positive relationships and support. Furthermore, pre-service teachers need practicum experience throughout their coursework, at a time when some may not yet be ready to lead full classes in their content area. The author offers lessons learned after five semesters of facilitating a pre-service teacher/ middle school youth mentoring program as a case study in hopes to encourage such programs’ implementation into teacher education programs as well as research into such a program’s usefulness.
Polls and Elections: Socioemotional Selectivity Theory and Vote Choice

Socioemotional selectivity theory posits that individuals invest more selectively in goals and activities that are emotionally meaningful as they age and time horizons gradually shrink. We extend socioemotional selectivity theory to the domain of voting in elections. We use data from the 2012 American National Election Study to test the hypothesis that older voters would place greater emphasis on emotional reactions to the candidates in their presidential voting, relative to younger voters. The empirical evidence suggests support for this contention, implying socioemotional selectivity extends to voting.
Prosthetic Arm and Arm Strap and Control for Paralysed People and Arm Amputees

This paper focuses on the design of a prosthetic arm (a forearm robotic arm as well as a complete robotic arm) using switches and thoughts to control them. Switch control is done by embedding switches and toggling them accordingly. The key of thought control lies in the mapping of the EEG signal of the subject to the 2D cursor through signal processing to achieve the objective. We designed low cost and reliable devices for switch control as well as thought control. The advantages of the design are (i) cost prohibitive and reliability (ii) attains a high-resolution EEG signal after transmission for signal processing. (iii) its universal usability irrespective of their age and social status. Key words—Bionic arm, thought control, EEG, 2D.
The Biogeography of Marine Communities

arine biogeography originated in the mid-1800s as a descriptive science that attempted to chart the current and past geographic distributions of taxa (Dana 1853). Classic biogeographers focused on mapping distributional provinces of species, genera, and other taxonomic groups (reviewed by Briggs 1974), and thus the fi eld was “systematic and historical, rather than ecological, in its approach” (Hedgpeth 1957). The biogeography of ecological units (i.e., communities) was rarely considered until many years later (Hedgpeth 1957; Thorson 1957), and even then, understanding progressed slowly. Robert MacArthur’s pioneering book Geographical Ecology was one of the fi rst signifi cant attempts to integrate biogeography and ecological theory (MacArthur 1972). Next, Geerat Vermeij, who began his career as an undergraduate student with MacArthur, further integrated biogeography and ecology by considering morphological adaptations of marine taxa along abiotic and biotic gradients. His book Biogeography and Adaptation provided a global perspective on the evolution of biological pattern, process, and diversity (Vermeij 1978). Nearly 20 years later, James Brown’s book Macroecology furthered the case for interdisciplinary synthesis and encouraged ecologists to consider patterns and processes that occur over the broader spatial and temporal scales traditionally studied by biogeographers (Brown 1995). When Brown’s book was published in 1995, marine community ecologists were primed to embrace its messages, as the fi eld was in the midst of rediscovering the openness of marine ecosystems and the importance of large-scale processes such as larval recruitment (Dayton and Tegner 1984; Underwood and Denley 1984; Roughgarden et al. 1988). Since that time, marine ecologists have increasingly focused on questions related to large-scale ecological patterns and processes. Substantial progress in addressing some of these questions is highlighted in the book Marine Macroecology (Witman and Roy 2009). This chapter focuses on understanding how and why assemblages of interacting marine species vary over large geographic scales. The accurate description of biogeographic patterns is a necessary starting point for these investigations (Underwood et al. 2000). Until recently, there have been few high-resolution data sets that describe how the composition and structure of marine communities vary over large spatial scales. Biogeographic treatments of marine fauna and fl ora generally illustrate range endpoints of species’ distributions, but seldom include information regarding spatial variation in population abundances or community composition. On the other hand, most marine ecologists have historically worked at one or a few fi eld sites, gaining little insight into variation in community structure over broader spatial scales. Fortunately, the number of studies conducted across latitudinal gradients has increased in the past decade. Much of this research has been on benthic community M
Growth of Desmodesmus subspicatus green microalgae and nutrient removal from sugarcane vinasse clarified by electrocoagulation using aluminum or iron electrodes

Sugarcane ethanol production generates considerable quantities of vinasse, its main wastewater. Microalgae cultivation is a promising option for effluent remediation, since the generated biomass can be feedstock for biofuel and bio-based chemical production. Due to vinasse high turbidity, pretreatment is necessary to clarify this effluent, adapting it as a mixotrophic culture medium. In this context, the present research evaluated the integrated process of electrocoagulation (EC) of sugarcane vinasse with aluminum or iron electrodes and subsequent cultivation of green microalgae Desmodesmus subspicatus. Results indicate pH neutralization and high turbidity removal efficiency by EC with both electrode materials. Aluminum EC and subsequent microalgae cultivation removed 66 and 75% of initial total organic carbon and total nitrogen, respectively, with biomass productivity of 1.45 g L-1day-1 and maximum specific growth rate of 0.095 h-1. Microalgae productivity was inferior in vinasse pretreated by iron EC, suggesting possible interference of ferric compounds in the microalgal development.
Mental Disability and the Cooperative System

I should like to thank the promoters and organizers of this congress especially for offering Turin and those working in psychosocial rehabilitation an opportunity to stop and reflect on what we have been doing; public discussion of our experiences and comparison with others' can help us emerge from the isolation in which we are used to working. Turin, which seems so stable in this ever-changing Italy, is a city rich in culture, science, and associational life, which has become well established over the years. But Turin is, at the moment, in the depths of a crisis that has grave ramifications for employment and the administration of the city ramifications that are reflected in the social fabric and the quality of our lives. In our own work, the crisis is expressed in a gradual reduction in resources available for mental health services and for assistance to the weaker segments of society. I should like to begin by briefly recalling how the cooperative system was born and how it has evolved. I shall then come back to the topic indicated in my title. The cooperative system was born not so much as an entrepre-
Brain tumor diagnosis based on artificial neural network and a chaos whale optimization algorithm

Accurate and early detection of the brain tumor region has a great impact on the choice of treatment, its success rate, and the follow‐up of the disease process over time. This study presents a new bioinspired technique for the early detection of the brain tumor area to improve the chance of completely healing. The study presents a multistep technique to detect the brain tumor area. Herein, after image preprocessing and image feature extraction, an artificial neural network is used to determine the tumor area in the image. The method is based on using an improved version of the whale optimization algorithm for optimal selection of the features and optimizing the artificial neural network weights for classification. Simulation results of the proposed method are applied to FLAIR, T1, and T2 datasets and are compared with different algorithms. Three performance indexes including correct detection rate, false acceptance rate, and false rejection rate are selected for the system performance analysis. Final results showed the superiority of the proposed method toward the other similar methods.
