Authors: Guangyue Wang , Jiong Li , Feifan Ye , Guorui Sun
Published: February 2017

Based on the analysis of the classification criteria from various factors,a comprehensive evaluation system of the erosion stability of the vegetated eco-slope protected by 3D geomat is established. To solve the problem of uncertainty in the slope erosion stability analysis and consider the feature of both of random and fuzziness, the theory of Cloud Model has been applied into comprehensive evaluation to realize the uncertainty conversion between the qualitative concept and the quantitative data. By constructing the qualitative rule generator, the specific score of the evaluation index is determined according to the uncertain reasoning. The weights of the evaluation indexes are determined with the help of the Analytic Hierarchy Process developed by Cloud Model (CM-AHP), and then the overall score of the comprehensive evaluation system is obtained. The results of engineering examples demonstrate the practicability and effectiveness of the assessment model, which provides a new way for the evaluation of the erosion stability of the vegetated eco-slope protected by the 3D geomat.
Gas-Water Flow Behaviour During Mutual Displacement in Porous Media
Authors: Cao Renyi , Xu Junjie , Yang Xiaoping , Jiang Renkai , Chen Changchao
Published: February 2017

During oilfield development, there exist multi-cycle gas–water mutual displacement processes. This means that a cycling process such as water driving gas–gas driving water–water driving gas is used for the operation of injection and production in a single well (such as foam huff and puff in single well or water-bearing gas storage). In this paper, by using core- and micro-pore scales model, we study the distribution of gas and water and the flow process of gas-water mutual displacement. We find that gas and water are easier to disperse in the porous media and do not flow in continuous gas and water phases. The Jamin effect of the gas or bubble becomes more severe and makes the flow mechanism of multi-cycle gas–water displacement different from the conventional water driving gas or gas driving water processes. Based on experiments of gas–water mutual displacement, the changing mechanism of gas–water displacement is determined. The results indicate that (1) after gas–water mutual displacement, the residual gas saturation of a gas–water coexistence zone becomes larger and the two-phase zone becomes narrower, (2) increasing the number of injection and production cycles causes the relative permeability of gas to increase and relative permeability for water to decrease, (3) it becomes easier for gas to intrude and the invaded water becomes more difficult to drive out and (4) the microcosmic fluid distribution of each stage have a great difference, which caused the two-phase region becomes narrower and effective volume of gas storage becomes narrower.

Визуализация поверхности проведена с помощью электронного микроскопа, а приповерхностного слоя с профилированием по глубине с помощью картирования элементов методом оже-электронной спектрокопии. Анализ распределения примесных ионов в кремнии проводился на времяпролетном вторично-ионном масс-спектрометре. Методом рентгеновской фотоэлектронной спектроскопии исследовано химическое состояние атомов матрицы кремния и примесных атомов цинка и кислорода, а также уточнен фазовый состав имплантированного и отожженных образцов. После имплантации Zn наблюдаются два максимума его концентрации: на поверхности пластины и на глубине 70 нм, при этом на поверхности и в приповерхностном слое происходит образование наночастиц фазы металлического Zn и фазы ZnO с размером порядка 10 нм. После отжига в кислороде в Si вблизи поверхности обнаружена фаза ZnO·Zn2SiO4, а на глубине 50 нм фаза Zn·ZnO. DOI: 10.21883/FTP.2017.02.44102.8285
К теории адсорбции на графеноподобных соединениях
Authors: Давыдов С.Ю.
Published: February 2017

На основании предложенной ранее модели электронного спектра бинарных графеноподобных соединений типа ANB8-N построена теория адсорбции, позволяющая выявить роль положения уровня адатома, величины константы взаимодействия адатом-подложка и ширины щели, присущей в свободном состоянии графеноподобному соединению с гетерополярными связями, в формировании электронной структуры адатома. Рассмотрены случаи свободных и эпитаксиальных графеноподобных соединений на поверхности металла. В случае свободных графеноподобных соединений анализ показал, что при больших и промежуточных значениях константы связи адатом-графеноподобное соединение основной вклад в число заполнения адатома na дают локальные состояния, тогда как с уменьшением константы связи возрастает вклад валентной зоны графеноподобного соединения. Основной особенностью эпитаксиального графеноподобного соединения на металле является отсутствие щели и, как следствие, вклада локальных состояний адатома в na. Оценки показали, что изменения констант связей адатом-подложка и графеноподобное соединение-металл влияют на величину na практически одинаковым образом. При этом зависимость na от ширины щели графеноподобного соединения с качественной точки зрения критичной не является. Кратко обсуждается адсорбция на структуре графеноподобное соединение-полупроводник. DOI: 10.21883/FTP.2017.02.44110.8336

Published: February 2017

Исследованы спектры возбуждения люминесценции локализованных экситонов в твердых растворах GaSe0.85Te0.15 при T=2 K. Показано, что в спектрах возбуждения экситонов с энергией локализации varepsilon> 10 mV возникает дополнительный максимум ME, расположенный с низкоэнергетической стороны от максимума, соответствующего полосе поглощения свободного экситона с n=1. Установлено, что сдвиг положения максимума ME в спектре возбуждения относительно энергии детектируемых фотонов увеличивается по мере уменьшения энергии детектируемых фотонов, то есть с увеличением энергии локализации экситонов. При резонансном возбуждении локализованных экситонов монохроматическим светом из области полосы экситонного излучения в спектре экситонной люминесценции с низкоэнергетической стороны от линии возбуждения также наблюдается максимум излучения (ML). Энергетическое расстояние между положением возбуждающей линии и положением максимума в спектре излучения увеличивается по мере уменьшения частоты возбуждающего света. Рассматриваются возможные механизм появления описанной структуры спектров возбуждения и экситонной люминесценции в GaSe0.85Te0.15. Сделан вывод, что максимумы ME в спектре возбуждения и ML в спектре излучения обусловлены электронно-колебательными переходами с рождением и аннигиляцией локализованных экситонов соответственно.

Leadership effectiveness in managing change, motivating employees and communication and the influence of leadership styles
Authors: Ramcharan Rabindranath S. , Parumasur Sanjana Brijball
Published: February 2017

This study assesses first line supervisors’ perceptions of the effectiveness of leadership in managing the change process. This is analyzed in terms of employee’s perceptions of the effectiveness of leadership communication, ability to motivate staff and to effectively manage change. The prevailing leadership styles are also assessed. The study was undertaken in a municipal fire and emergency services division in KwaZulu-Natal, South Africa and the population comprises of 60 first line supervisors from which a sample of 52 employees was drawn using the systematic sampling technique. Data was collected using an established questionnaire that was modified for the purposes of this study. The psychometric properties of the questionnaire (validity and reliability) were assessed using Factor Analysis and Cronbach’s Coefficient Alpha respectively. Data was analyzed using descriptive and inferential statistics. The results indicate that first line supervisors believe that the leadership of the organization is able to effectively manage change though improvement is needed in terms of their ability to motivate employees and communicate effectively. The dominant leadership style is autocratic leadership followed by impoverished leadership styles which explains the lower concern for motivation and communication that surfaced in this organization. The study also found that only team/participative leadership style correlates significantly with leaders’ potential to motivate employees, communicate and manage change respectively. Recommendations are made to enhance leadership effectiveness
An empirical study of IPO underpricing: Evidence from Chinese stock market
Authors: Xu Tianxiang , Zhao Yujie
Published: February 2017

Initial public offerings, as one of the most important activities for firms, have raising massive amount of researches. Regarding China, the stock markets are experiencing a massive level of IPO underpricing, which leads to trillions of dollars leaved on the table. This study is conducted for the question why Chinese IPO are so heavily underpriced and the determinants of IPO underpricing, also the possibility of IPO be underpriced in China. We confirm again that Chinese IPOs are heavily underpriced and the average underpricing level is about 110%. Further, Chinese IPO will experience a negative short term return starting from 10 days after listing, and there are significantly different characteristics for state owned IPOs and private IPOs. This study finds that information asymmetry, proportion of state owned share and risk are the mainly determinants of IPO underpricing in China. Additionally, one of the biggest reason that Chinese initial public offering is underpriced so much is because of government participation, since we find that firms with larger proportion of government state owned shares will be more underpriced.
Are efficient CEOs higher remunerated? A data envelopment analysis of selected Johannesburg security exchange companies
Authors: Oberholzer Merwe
Published: February 2017

The originality of the study is that performances of CEOs are estimated by determining how efficiently they convert their own remuneration and other key company input resources into a key performance output. Accounting-based data, with the Du Pont analysis as conceptual framework, were applied as the other company input and output determinants. The main purpose was to determine whether there is a difference in remuneration of CEOs who are efficient and inefficient, as estimated by data envelopment analysis. A sample of 167 Johannesburg Stock Exchange-listed companies, divided into large, medium and small, from the industrial and resource sectors is empirically investigated. According to the Student t test, the study found that there is no statistically significant difference between the remuneration of efficient and inefficient CEOs of large and small companies, but for medium-sized companies, the inefficient CEOs are statistically significantly higher remunerated. A possible reason for this contradiction is, inter alia, that market-based performance determinants were not taken into account, which could lead to a different conclusion. The practical implication is that an accounting-based model is developed for company boards, which should consider using accounting-based data more frequently to benchmark their CEOs’ remuneration, since not only are these data readily available to make comparisons with peers, but it can be influenced more easily by a CEO as in the case of market-based determinants

Introduction/Objective. Childhood obesity is an emerging public health problem. The national prevalence of child overweight/obesity in Montenegro has increased by one third in the last decade. As the overwhelming majority of Montenegrin population is urban, investigation of obesity and correlates among urban children is of special public health interest. The aim of this study was to investigate the prevalence of and contributing factors to obesity among schoolchildren of Podgorica. Method. The sample included 1,134 schoolchildren (49.8% boys) aged 7?12 years, from 10 elementary schools in Podgorica. We measured children?s body mass, body height, and waist circumference to calculate body mass index (BMI) and waist-to-height ratio. The research instrument was a closed type of the original questionnaire. Nutritional status was assessed according to the criteria recommended by the American Centers for Disease Control and Prevention, World Health Organization and International Obesity Task Force. Results. Among the investigated children there were 21.2% and 6% overweight and obese children, respectively. Obesity was more frequent among boys (7.6%) compared to girls (4.4%). In a multiple regression, childhood obesity was positively related to the following: male gender, younger age, lower number of siblings, parental obesity, and low physical activity. Conclusion. One out of five urban Montenegrin schoolchildren is overweight/obese, with obesity being twice as frequent among boys compared to girls. A program against obesity among urban Montenegrin children should focus on the revealed contributing factors.

Over the last decade isoindigo derivatives have attracted much attention due to their high potential in pharmacy and in the chemistry of materials. In addition, isoindigo derivatives can be modified to form supramolecular structures with tunable morphologies for the use in drug delivery. Amphiphilic long-chain dialkylated isoindigos have the ability to form stable solid nanoparticles via a simple nanoprecipitation technique. Their self-assembly was investigated using tensiometry, dynamic light scattering, spectrophotometry, and fluorometry. The critical association concentrations and aggregate sizes were measured. The hydrophilic–lipophilic balance of alkylated isoindigo derivatives strongly influences aggregate morphology. In the case of short-chain dialkylated isoindigo derivatives, supramolecular polymers of 200 to 700 nm were formed. For long-chain dialkylated isoindigo derivatives, micellar aggregates of 100 to 200 nm were observed. Using micellar surfactant water-soluble forms of monosubstituted 1-hexadecylisoindigo as well as 1,1′-dimethylisoindigo were prepared for the first time. The formation of mixed micellar structures of different types in micellar anionic surfactant solutions (sodium dodecyl sulfate) was determined. These findings are of practical importance and are of potential interest for the design of drug delivery systems and new nanomaterials.
Making Links Between Solutions to an Unstructured Problem
Authors: Evans Sheila
Published: February 2017

In the study described here, teaching resources have been developed to provide students with explicit opportunities to link invariant properties across a range of different solution strategies, and make comparative judgments about the same solutions. After tackling an unstructured problem, students complete, compare and critique pre-designed student responses to the same problem. The framework used to analyze the data focuses on the types of links students may make between responses. The findings indicate students made varied links when completing them. The outcome of these links appeared to be influenced by how students perceived the representation being completed. Students made further assorted links that focused on invariant properties and the comparative validity of the completed responses.

IoT is an acronym for Internet of Things. It is the revolutionary area that transforms the digital world into a device world. IoT helps in not only fulfilling human requirements, but also they act as a communication medium between humans and electronic devices. The birth of IoT started in early 2000s, but since then, it is an amazing fact that now at least 65% of devices are connected with IoT technology with the term “smart” in their prefix and it would be up by 30% at the end of 2016 (Gartner Survey, 2015). Since then, many security issues were raised, and have been risen all these years due to the flaws in that devices. This made attackers to take advantage over that devices and started controlling them. This chapter studies IoT application layer protocols, services offered and gives an idea of existing cyber attacks and threat. In addition, the authors give the possible attacks on the IoT devices, in particular at application layer, and give the necessary precautions to overcome the cyber attacks both for consumers and vendors.

The automotive industry has reached a stage categorisation of the degree of the automation has become crucial. According to the levels of automation defined by SAE, the automotive industry is already past the first four and development is now being heavily concentrated on level 5, that is, driving independent of human control. This obviously requires an array of sensors, microcontrollers and visual feedback systems like cameras, LiDAR (Light Detection and Ranging) to be present in the vehicle. With security concerns omnipresent among these devices, they are now ported to the realm of vehicles and must be tackled so that unsafe driving conditions are never experienced. In this paper, Section 3 elaborates upon the technologies that have shaped autonomous cars into the form known today and Section 4 explains the network architecture and network security amongst these cars. Section 5 describes the rippling effect of this evolution in the automotive industry on other supportive industries, Section 6 talks about the challenges posed to the development of AVs and finally, Section 7 discusses the future of autonomous vehicles in India.
A Literature Review on the Viral Advertising Narrative Structure
Authors: Koçyiğit Murat
Published: February 2017

Viral advertising relies on consumers' transmitting the message to other consumers within their online social media. Viral advertising is controlled by consumers and is less under the control of advertisers and brands (Petrescu, 2014). Consumers receive the link or the advertising content and pass it along through e-mail or posting it on a blog, microblog, podcast, wiki, form, webpage, and social media profile. Advertising narrative in traditional media has changed with viral ads. In the narrative of viral advertising is more emotional, romantic, humorous, sexual and contains social messages. This study was conducted to examine the Brands' viral advertising narrative. Viral advertising is at an early stage of development and much of the current viral marketing communication literature research is concerned with understanding the motivations and behaviours of those passing-on email messages. No longer the preserve of offline communication strategists, it is becoming a central platform for interactive marketing communications (Cruz & Fill, 2008).

Published: February 2017

El profesor Octavio Ruiz-Manjón ha publicado en el año 2016 su último libro, que lleva por título Algunos hombres buenos. Historias de mujeres y hombres que pusieron la justicia por encima de las ideologías durante la Guerra Civil. En esta obra analiza los comportamientos de un número de personas que intentaron no sucumbir a la ola de violencia, que supieron distinguir los comportamientos más injustos cometidos por el bando en el que quedaron atrapados y actuar en defensa del derecho a la vida de sus adversarios políticos. El presente artículo pretende contribuir a esta propuesta temática añadiendo un nuevo nombre a ese listado a través del estudio de una causa sumarísima sobre un republicano. Rescatar la experiencia de estos individuos puede ofrecernos enseñanzas y reflexiones sobre comportamientos sociales en escenarios de intensa violencia política, pero también nos ayuda a descubrir los muchos que con sus gestos, actitudes y decisiones puntuales trataron de contrarrestar esa violencia, la mayoría de ellos anónimos y olvidados.
El año del fútbol. La emigración polaca en España y algunas iniciativas de solidaridad con Solidarność (1981-1989)
Authors: Faraldo José M.
Published: February 2017

La emigración polaca en España fue históricamente muy escasa. De ahí que las acciones de ayuda y apoyo a Solidarność resultaran muy débiles en comparación con otros países europeos. Hubo por un lado una cierta solidaridad por parte de miembros del sindicato polaco con apoyo de sindicalistas españoles y hubo una leve acción de envío de ayuda económica por parte de los nuevos refugiados y de la más antigua colonia proveniente de la época de posguerra. En definitiva y, pese a su pequeño tamaño, la Polonia española no dudó en mantener lazos con sus atribulados compatriotas en el país
La representación rigurosa del origen de la violencia machista en la prensa escrita: una propuesta de medición
Authors: Peris Vidal Manuel
Published: February 2017

A pesar del gran número de manuales de recomendaciones sobre el tratamiento de la violencia machista en los medios de comunicación difundidos desde finales del siglo XX, creemos que es necesaria una mejor formación de los periodistas que trabajan en la prensa española para que puedan transmitir a la ciudadanía una imagen rigurosa de la violencia machista. Con este fin, se ha elaborado una serie de indicadores para medir la exactitud en la imagen que se transmite sobre el origen de la violencia. Esta medición se ha realizado sobre las noticias de los diarios ABC, El Mundo y El País del año 2015, y se han estudiado los mensajes falsos sobre las causas de la violencia de género que se transmiten por medio de la prensa escrita.

Das amostras analisadas 5,79% eram positivas para parasitas, sendo 3,16% de cistos de Entamoeba coli, 1,58% Endolimax nana e 1,05% Giardia lamblia. Sobre os conhecimentos relacionado a parasitas, 73,16% relataram saber da existência dos parasitas e o que eles causam no indivíduo e 68,42% conhecem os meios de transmissão, porém 41,58% consideram insuficientes as informações disponíveis para a população. Referente às condições sanitárias as quais estão expostos, 94,21% consomem água potável e 64,74% afirmaram ter coleta e tratamento de esgoto. O presente estudo teve baixa frequência de parasitoses, isso pode ser explicado pelo conhecimento dos responsáveis, pelas condições sanitárias favoráveis, e pelo alto percentual (78,95%) de escolares que já fizeram uso de antiparasitários.

Este estudo discute uma intervenção organizacional em uma empresa
terceirizada do ramo da aviação civil, tendo como base algumas vertentes
das chamadas clínicas do trabalho, especialmente a clínica da atividade e a
psicossociologia do trabalho. Na ótica da pesquisa qualitativa, utilizaramse
de procedimentos como observação da situação de trabalho, entrevistas
individuais e grupos de discussão, visando inicialmente a um diagnóstico
dos problemas da organização. Em seguida, criou-se um dispositivo de
participação dos trabalhadores, por meio de um recurso gerencial denominado
desenvolvimento de habilidades humanas (DHH), destinado a reorganizar
os processos de trabalho da empresa. A questão dos mecanismos internos
de poder é também abordada neste estudo, bem como o alcance do poder
de agir dos trabalhadores. Entende-se que este estudo possa contribuir para
novas alternativas de inserção do psicólogo nas organizações do trabalho.

Enfermedad mental, fotoperiodismo e Internet: hacia una visión más humana y normalizadora
Authors: Pardo Sainz Rebeca
Published: February 2017

Las imágenes de publicaciones médicas y de los medios de comunicación más tradicionales habían logrado crear una iconografía estigmatizante contra la que se manifiestan asociaciones y afectados de estas enfermedades, a los que las redes sociales como Instagram y los blogs ofrecen una vía, hasta hace poco tiempo impensable, que democratiza la posibilidad de representar y difundir el día a día con la enfermedad mental, incluso en fotoperiodismo. Un elevado número de estas imágenes son tomadas y compartidas por los propios afectados por este tipo de enfermedades o por sus familiares, que afrontan la frialdad de las representaciones “científicas” y supuestamente “objetivas” previas con unas instantáneas que se centran más en los seres humanos y los sentimientos que hay tras estos casos.

The aim of our article is to study the incidence, diagnosis, and treatment of bowel perforation by foreign body ingestion. Bowel perforation by foreign body ingestion has been believed to be relatively rare, and most commonly caused by fish bones, chicken bones, and toothpicks. Our clinical experience, however, suggests such perforations may be more common than previously thought, and caused by various other objects as well. Medical records of all patients diagnosed with foreign body–induced intestinal perforation, from the Department of General Surgery at Tonji Hospital, from January 2000 to June 2015, were retrospectively analyzed. A total of 17 men and 8 women suffered intestinal perforations by ingestion of dietary foreign bodies. Among the 25 total patients, 4 ingested foreign bodies intentionally, whereas the other 21 cases were accidental. The foreign bodies were identified by plain X-ray film in 2 patients (2 cases of needles) and by multidetector computed tomography (MDCT) in 11 patients (6 cases of date stones, 3 cases of metallic objects, and 2 cases of bone fragments), thus supporting the correct preoperative diagnosis (13 cases; 52%). The most common location of the perforation was the terminal ileum (n = 17). The offending objects were date stones (n = 13), bones (n = 7), and metallic objects (n = 5). The most common treatment was removal of the foreign body and closure of the perforation with simple suture (n = 22). Ten patients were treated laparoscopically. The present study shows that the most common foreign bodies causing intestinal perforation are date stones and bones. Although about 50% of the foreign bodies could be identified by MDCT, definite diagnosis remained preoperatively difficult. Consequently, because of high misdiagnosis rates, laparoscopy may be the optimal choice for diagnosis and treatment of bowel perforation by foreign bodies.
Electrochemical Sensor‐Based Ruthenium Nanoparticles on Reduced Graphene Oxide for the Simultaneous Determination of Ethinylestradiol and Amoxicillin

Published: February 2017

The composite material of reduced graphene and Ru nanoparticles (rGO/RuNP) was obtained by electrochemical oxidation of ruthenium nanoparticles immobilised on the glassy carbon electrode (GCE) surface and used for simultaneous electroanalysis of drugs. There are many discussions in the scientific community about the decrease in therapeutic efficacy of contraceptives when associated with antibiotics. The antibiotic effect of the antagonist can increase the contraceptive excretion levels in urine, indicating a reduction in the body and thus a decrease in the desired effect. Using the DPV technique, it was possible to quantify ethinylestradiol (EE2) and amoxicillin (AMX) with a linear response range, 5.50x10−8 – 1.20x10−6 mol L−1, and LOD, 2.04 nmol L−1 and 1.63 nmol L−1, respectively. The results for the electrochemical behaviour of EE2 and AMX using GCE/rGO/RuNP were compared with GCE/rGO and GCE. The GCE/rGO/RuNP showed greater stability and separation anodic peak currents, suitable for the quantification of organic molecules in samples of environmental interest, as well as clinical and food samples.

Metabasin transitions are Johari-Goldstein relaxation events
Authors: Cicerone Marcus T. , Tyagi Madhusudan
Published: February 2017

We show that by representing quasi-elastic and inelastic neutron scattering from propylene carbonate (PC) with an explicitly heterogeneous model, we recover signatures of two distinct localized modes in addition to diffusive motion. The intermediate scattering function provides access to the time-dependence of these two localized dynamic processes, and they appear to correspond to transitions between inherent states and between metabasins on a potential energy landscape. By fitting the full q-dependence of inelastic scattering, we confirm that the Johari-Goldstein (βJG) relaxation in PC is indistinguishable from metabasin transitions.
A simple method for calculating the productivity of polyphenol separations by polymer-based chromatography

Published: February 2017

A simple method for calculating the productivity of chromatography processes was proposed based on the iso-resolution curve concept. The model separation system was polyphenol separations by polystyrene divinylbenzene resins with the ethanol–water mixture mobile phase. The distribution coefficient K was determined as a function of ethanol concentration I by linear gradient elution experiments. The HETP-mobile phase velocity u curves were determined as a function of I. Using K and HETP, the iso-resolution curve was calculated, from which the productivity was determined as a function of I. It was found that there is an optimum I, where the highest productivity with the minimum amount of mobile phase consumption is obtained.

Senescence is a form of cell cycle arrest induced by stress such as DNA damage and oncogenes. However, while arrested, senescent cells secrete a variety of proteins collectively known as the senescence-associated secretory phenotype (SASP), which can reinforce the arrest and induce senescence in a paracrine manner. However, the SASP has also been shown to favor embryonic development, wound healing, and even tumor growth, suggesting more complex physiological roles than currently understood. Here we uncover timely new functions of the SASP in promoting a proregenerative response through the induction of cell plasticity and stemness. We show that primary mouse keratinocytes transiently exposed to the SASP exhibit increased expression of stem cell markers and regenerative capacity in vivo. However, prolonged exposure to the SASP causes a subsequent cell-intrinsic senescence arrest to counter the continued regenerative stimuli. Finally, by inducing senescence in single cells in vivo in the liver, we demonstrate that this activates tissue-specific expression of stem cell markers. Together, this work uncovers a primary and beneficial role for the SASP in promoting cell plasticity and tissue regeneration and introduces the concept that transient therapeutic delivery of senescent cells could be harnessed to drive tissue regeneration.

The spinal cord is the primary neurological link between the brain and other parts of the body, but unlike those of the brain, advances in spinal cord imaging have been challenged by the more complicated and inhomogeneous anatomy of the spine. Fortunately with the advancement of high technology, phase-contrast synchrotron radiation microtomography has become widespread in scientific research because of its ability to generate high-quality and high-resolution images. In this study, this method has been employed for nondestructive imaging of the internal microstructure of rat spinal cord. Furthermore, digital virtual slices based on phase-contrast synchrotron radiation were compared with conventional histological sections. The three-dimensional internal microstructure of the intramedullary arteries and nerve fibers was vividly detected within the same spinal cord specimen without the application of a stain or contrast agent or sectioning. With the aid of image post-processing, an optimization of vessel and nerve fiber images was obtained. The findings indicated that phase-contrast synchrotron radiation microtomography is unique in the field of three-dimensional imaging and sets novel standards for pathophysiological investigations in various neurovascular diseases.
