Increasing the effective bandwidth of seismic data through sparse-layer inversion: A case study from Mangala field, Rajasthan, India
Authors: Somasundaram Sreedurga , Chacko Soman , V Ravichandran , van Eykenhof Robert
Published: December 2014

Mangala field is in the northern part of the onshore Barmer Basin in India. The primary reservoir in the field is the Fatehgarh Formation, deposited in the rifting phase that created the Barmer Basin during the Late Cretaceous to early Paleocene period. The majority of reservoir oil is contained within the upper FM1 member of the Fatehgarh Formation, composed of single-story and multistory stacked, meandering-channel sands. These sands vary in thickness from 3 to 7 m, with net to gross ranging from 18% to 78%. For such a heterogeneous fluvial system, correlation of floodplain shales and fluvial sands poses a major challenge for reservoir characterization when based on well data alone. Conventional 3D seismic data do not resolve the thin FM1 sands. For more accurate reservoir modeling, various techniques, which included sparse-spike inversion and spectral decomposition, were attempted with limited success. Sparse-layer reflectivity inversion performed on 3D stack PSTM seismic data, however, resulted in improved detectability and resolution and has provided a greater understanding of the lateral continuity of these thin fluvial reservoir units. The 7- to 50-Hz bandwidth of the input seismic data increased to 7 to 100 Hz by the inversion process. The improved imaging of channel geometries has enabled geobody mapping and their input into a revised geologic model.

Melatonin Regulates Somatotrope and Lactotrope Function Through Common and Distinct Signaling Pathways in Cultured Primary Pituitary Cells From Female Primates
Authors: Ibáñez-Costa Alejandro , Córdoba-Chacón José , Gahete Manuel D. , Kineman Rhonda D. , Castaño Justo P. , Luque Raúl M.
Published: December 2014

Melatonin (MT) is secreted by the pineal gland and exhibits a striking circadian rhythm in its release. Depending on the species studied, some pituitary hormones also display marked circadian/seasonal patterns and rhythms of secretion. However, the precise relationship between MT and pituitary function remains controversial, and studies focusing on the direct role of MT in normal pituitary cells are limited to nonprimate species. Here, adult normal primate (baboons) primary pituitary cell cultures were used to determine the direct impact of MT on the functioning of all pituitary cell types from the pars distalis. MT increased GH and prolactin (PRL) expression/release in a dose- and time-dependent fashion, a response that was blocked by somatostatin. However, MT did not significantly affect ACTH, FSH, LH, or TSH expression/release. MT did not alter GHRH- or ghrelin-induced GH and/or PRL secretions, suggesting that MT may activate similar signaling pathways as ghrelin/GHRH. The effects of MT on GH/PRL release, which are likely mediated through MT1 receptor, involve both common (adenylyl cyclase/protein kinase A/extracellular calcium-channels) and distinct (phospholipase C/intracellular calcium-channels) signaling pathways. Actions of MT on pituitary cells also included regulation of the expression of other key components for the control of somatotrope/lactotrope function (GHRH, ghrelin, and somatostatin receptors). These results show, for the first time in a primate model, that MT directly regulates somatotrope/lactotrope function, thereby lending support to the notion that the actions of MT on these cells might substantially contribute to the define daily patterns of GH and PRL observed in primates and perhaps in humans.
The Modern Society: Information or Communication?
Authors: Goykhman Oskar
Published: December 2014

The article is devoted to the analysis of the processes taking place in our modern society. Opinion of a number of investigators about the role played by information in the society is that information is the essence of our modern society. It is from this point of view that revolutionary changes passed by mankind during all history of the development are presented. The concept of understanding the modern society as information one is thought of critically. The hypotesis about communication society as a form of joint activity of people is put forward. Information is perceived as a means to accelerate society progress rather than the society itself. The question “how often revolutionary processes in society happen” is considered from the standpoint of communication science. It is argued that the fifth communicative revolution which gave rise to communication society is taking place now. Stages of progress of this society are closely connected with the Internet-communication processes. The reasons for people’s turning to the Internet and both positive and negative consequences of this phenomenon are studied.
The Value of Funds of Hedge Funds: Evidence from Their Holdings
Authors: Aiken Adam L. , Clifford Christopher P. , Ellis Jesse
Published: December 2014

We examine the portfolio holdings of funds of hedge funds (FoFs) to identify the channels through which FoFs add value for their clients. FoFs offer access to a diversified portfolio of funds that would be costly for constrained investors to manage on their own. Although we find only limited evidence that FoFs exhibit skill when selecting hedge funds, we find strong evidence that FoFs make skillful termination decisions. After FoFs divest from a hedge fund, those hedge funds subsequently underperform and fail more often. Our evidence indicates that FoFs learn and skillfully process information about their portfolio funds after they become investors, enabling them to forecast poor future performance. Our study suggests that FoFs serve an important role as intermediaries in a market characterized by significant frictions and transactions costs.

Student midwives’ knowledge of perinatal mental health
Authors: Jarrett Patricia
Published: December 2014

Background:

Psychiatric illness is a leading indirect cause of maternal mortality. Earlier studies suggest serious discrepancies in the training and knowledge of midwives with regard to perinatal mental health.

Aims:

To explore the knowledge and experience of student midwives in the care of women with perinatal mental health problems.

Methods:

A modified questionnaire was distributed to student midwives near completion of 3-year and 78-week midwifery programmes.

Results:

Students often under-estimated the risk of women with existing mental health problems developing a serious mental health problem during pregnancy or in the postpartum period. Students felt ill-prepared and lacked confidence in caring for women with serious mental health problems.

Conclusion:

Recommendations from the findings of this study indicate (1) a review of undergraduate midwifery education in relation to perinatal mental health is needed; (2) a larger study, involving a more diverse sample of students, would enable generalisation to a wider population.
Health professionals’ attitudes towards the promotion of breastfeeding
Authors: Marks Dougie , O'Connor Rory
Published: December 2014

Background:

Despite their important role in breastfeeding promotion, there is a lack of research regarding professionals’ attitudes towards breastfeeding, and the impact these may have on breastfeeding promotion.

Aim:

To investigate health professionals’ views regarding breastfeeding, the influences on those views, and how they impact the breastfeeding promotion.

Methods:

In this qualitative study, 10 focus groups were carried out with health professionals involved with breastfeeding promotion.

Results:

Several themes emerged. These were: powerlessness and pessimism, breastfeeding promotion vs coercion/education, and the function of breastfeeding promotion. Professionals felt positively towards breastfeeding, but saw their influence as minimal due to an array of external influences on the mothers’ decision. They felt that promotion was not always carried out appropriately, and were wary of moralising breastfeeding. Professionals felt their role was one of informing, rather than promotion.
Supervisory investigation as part of the wider risk management process
Authors: Hastings Chrissie
Published: December 2014

All qualified midwives must follow the Nursing and Midwifery Council (NMC) standards and guidance, and be fit to practise, so that women can trust them with their health and wellbeing. When a midwife is involved in a serious untoward incident, she will be subject to both the investigative procedures of her employer and her Local Supervising Authority. Two concurrent investigations can be perceived as adding a degree of confusion to the overall risk management process. This action can also be deemed as unfair to the midwife compared with the treatment given to other health professionals. This article critically appraises the value of this additional investigative process and examines the concepts of both accountability and responsibility and the implications this has for the midwife. Statutory supervision provides the midwifery service with midwives who have a working knowledge of the reality of the system and remain connected with those midwives on their caseload. The supervisory investigative process can offer a protective programme of training and education and in due course be instrumental in preventing the midwife facing further regulatory action.

A real-life clinical evaluation of a next-generation antimicrobial dressing on acute and chronic wounds
Authors: Walker M. , Metcalf D. , Parsons D. , Bowler P.
Published: December 2014

Objective:

To assess the effectiveness of a new, next-generation antimicrobial dressing (AQUACEL Ag+ dressing) in facilitating healing in a variety of hard-to-heal wounds that may have been compromised by infection and/or biofilm.

Method:

This was an international, multi-centred, real-life, non-randomised evaluation involving patients with a wide variety of slow-, non-healing or deteriorating chronic and acute wounds. There were no strict inclusion or exclusion criteria and the clinicians were asked to use their discretion in the selection of patients. The clinicians continued to use their standard protocol of care but replaced their existing primary wound-contact dressing with the next-generation antimicrobial dressing (NGAD) for up to 4 weeks. Clinicians could extend the treatment period if this was deemed clinically appropriate. Baseline assessments included wound bed characteristics, exudate level, indicators of wound biofilm, and signs and symptoms of infection. At the final assessment, the investigators reported the wound size, wound bed characteristics, and exudate level.

Results:

A total of 121 patients were recruited into the original evaluation, of which eight were excluded for incomplete data sets. Most wounds (73; 64%) were either venous leg ulcers (59; 52%) or diabetic foot ulcers (14; 12%). At baseline, the wounds of (26; 23%) patients were slowly improving, 65 were stagnant (58%) and 22 (19%) were deteriorating. Just under three-quarters (74%) of the wounds had suspected biofilm (criteria including failure of a wound to heal, lack of response to topical and systemic antimicrobial agents, or the presence of slimy substances on the wound surface). Following the evaluations, the average wound closure achieved for all wounds was 72.6%, 19 (17%) wounds healed, 47 (42%) achieved at least 90% wound closure, and 71 (63%) achieved at least 75% closure. The average treatment period was 4.1 weeks; 35 wounds were treated with the dressing for more than 4 weeks. Cost analysis indicated that potential antimicrobial dressing cost reductions of approximately 30% were realised using the NGAD.

Conclusion:

This real-life, non-randomised evaluation provides encouraging evidence that the NGAD may have a role to play in facilitating wound progression towards healing by helping to eliminate the biofilm barrier.

Prescribing compression stockings to prevent recurrent leg ulcers
Authors: Venable Jane
Published: December 2014

In this case study, a 69-year-old patient presents with a healed venous leg ulcer, a condition that can recur in 69% of patients. Evidence suggests the use of compression therapy can reduce the rate of recurrence of leg ulcers. Compression therapy is contraindicated in some patients, so the prescriber should undertake careful assessment before making the decision to prescribe.

Standard precaution and incidence of needle stick injury during children vaccination among nurses working in maternal and child health centers in El-Minia governorate
Authors: Hossein Yosria
Published: December 2014

Background: Persons administering vaccines should follow necessary precautions to minimize risk for spreading disease. Nurses have a significant role in this process and are responsible for implementing several infection control strategies. Syringes and needles used for injections must be sterile and disposable to minimize the risk of contamination. The Centers for disease Control and prevention (CDC) estimates that each year 384,000 needle sticks injuries (NSI) and other sharp â€“ related percutaneous injuries are sustained by hospital â€“ based healthcare personnel, an average of over 1,000 sharp injuries per day. The estimate is not including other health care settings, such as emergency services, outpatient Clinics home based care and nursing homes.Objective: This study aims to identify the standard precaution and the Incidence of Needle Stick Injury Among nurses working in Maternal and Child Health Centers during Children vaccination in El-Minia GovernorateMaterial and Method: Cross sectional study was utilized to meet the aim of the study, this study was conducted in the ten(10) minister center of health (MCH) at EL- Minia from May to August 2012, the Nurses participated in this study included (100) Nurses who are working in (M CH) center after receiving their consents for participation. Observation checklist was done to observe the nurses performance before, during and after child vaccine and procedure toward universal precaution.Results: that the highest frequency of nurses were in the age intervals 30<40 years with main age (34.3 Â± 9.4) all sample were females and secondary school degree in nursing. More than have of them 55%were having 10:20 years of experience in nursing, Relation between nurse's incidences of needle stick injury and their experience, show statistically significant differences. Also the relation between nurse's incidences of need stick injury and their training, were good with statistically significant differencesConclusion: The study showed a high prevalence of needle stick injuries and low of using standard precaution among nurses during vaccination the child so suggests that every MCH must have an infection control committeeÂ  for observation the using of standard precaution and training the nurses for prevention of needle stick injury.

Body composition, bone turnover, and bone mass in trans men during testosterone treatment: 1-year follow-up data from a prospective case–controlled study (ENIGI)
Authors: Van Caenegem E , Wierckx K , Taes Y , Schreiner T , Vandewalle S , Toye K , Lapauw B , Kaufman J-M , T'Sjoen G
Published: December 2014

Purpose

To assess the evolution of body composition and bone metabolism in trans men during the first year of cross-sex hormonal therapy.

Methods

In a prospective controlled study, we included 23 trans men (female-to-male trans persons) and 23 age-matched control women. In both groups, we examined grip strength (hand dynamometer), biochemical markers of bone turnover (C-terminal telopeptides of type 1 collagen (CTX) and procollagen 1 aminoterminal propeptide (P1NP)), total body fat and lean mass, and areal bone mineral density (aBMD) by dual-X-ray absorptiometry (DXA) and fat and muscle area at the forearm and calf, bone geometry, and volumetric bone mineral density (vBMD) by peripheral quantitative computed tomography (pQCT), before treatment and after 1 year of treatment with undecanoate (1000 mg i.m./12 weeks).

Results

Before hormonal treatment, trans men had similar bone and body composition compared with control women. Testosterone treatment induced in trans men a gain in muscle mass (+10.4%) and strength and loss of fat mass (−9.7%) (allP<0.001) and increased the levels of P1NP and CTX (bothP<0.01). Areal and volumetric bone parameters remained largely unchanged apart from a small increase in trabecular vBMD at the distal radius and in BMD at the total hip in trans men (P=0.036 andP=0.001 respectively). None of these changes were observed in the control group.

Conclusions

Short-term testosterone treatment in trans men increased muscle mass and bone turnover. The latter may rather reflect an anabolic effect of testosterone treatment rather than bone loss.
A novel role for GSK3 in the regulation of the processes of human labour
Authors: Lim Ratana , Lappas Martha
Published: December 2014

Preterm birth remains the largest single cause of neonatal death and morbidity. Infection and/or inflammation are strongly associated with preterm delivery. Glycogen synthase kinase 3 (GSK3) is known to be a crucial mediator of inflammation homeostasis. The aims of this study were to determine the effect of spontaneous human labour in foetal membranes and myometrium on GSK3α/β expression, and the effect of inhibition of GSK3α/β on pro-labour mediators in foetal membranes and myometrium stimulated with Toll-like receptor (TLR) ligands and pro-inflammatory cytokines. Term and preterm labour in foetal membranes was associated with significantly decreased serine phosphorylated GSK3α and β expression, and thus increased GSK3 activity. There was no effect of term labour on serine phosphorylated GSK3β expression in myometrium. The specific GSK3α/β inhibitor CHIR99021 significantly decreased lipopolysaccharide (ligand to TLR4)-stimulated pro-inflammatory cytokine gene expression and release;COX2gene expression and prostaglandin release; andMMP9gene expression and pro MMP9 release in foetal membranes and/or myometrium. CHIR99021 also decreased FSL1 (TLR2 ligand) and flagellin (TLR5 ligand)-induced pro-inflammatory cytokine gene expression and release andCOX2mRNA expression and prostaglandin release.GSK3βsiRNA knockdown in primary myometrial cells was associated with a significant decrease in IL1β and TNFα-induced pro-inflammatory cytokine and prostaglandin release. In conclusion, GSK3α/β activity is increased in foetal membranes after term and preterm labour. Pharmacological blockade of the kinase GSK3 markedly reduced pro-inflammatory and pro-labour mediators in human foetal membranes and myometrium, providing a possible therapeutics for the management of preterm labour.

Published: December 2014

En este estudio se evaluaron los cambios en la biomasa aérea almacenada y su dinámica en el tiempo en 9 parcelas permanentes pertenecientes a la red de parcelas de RAINFOR (Red Amazónica de Inventarios Forestales) ubicadas dentro del bosque húmedo tropical de la Reserva Nacional Tambopata en la llanura Amazónica. Se tomaron datos en campo con la metodología estandarizada RAINFOR. La biomasa se estimó usando la ecuación para bosques húmedos tropicales de Chave et al. (2005). La dinámica de la biomasa se analizó separándolos por periodos inter censales a partir del año 2003 hasta el 2011. Se registraron 64 familias, 219 géneros y 531 especies. La composición florística es muy similar en todas las parcelas excepto en la parcela de pantano. Son evidentes dos grupos ligeramente distintos y aparentemente relacionados a la edad de las antiguas terrazas fluviales de la zona. La tasa de mortalidad y reclutamiento de individuos presentan valores promedio de 2.12 ± 0.52% y 1.92 ± 0.49%, respectivamente. La tasa de reemplazo es 2.02% anual. La biomasa aérea almacenada fue de 296.2 ± 33.9 t ha-1 en promedio. La dinámica de la biomasa muestra una ganancia neta total de 1.96, 1.69 y –1.23 t ha-1 para cada periodo respectivamente. Antes de la sequía de 2010 se encontró un cambio en la biomasa de 1.88 t ha-1 año-1 y post sequía fue –0.18 t ha-1 año-1 en promedio, aunque la diferencia no fue significativa. El análisis demográfico sugiere un equilibrio dinámico en las parcelas. El balance negativo de biomasa observado para el periodo 2008 – 2011 puede deberse a la sequía del 2010, donde la mitad de las parcelas monitoreadas tuvieron una disminución en las ganancias netas de la biomasa por mortalidad de individuos afectando la composición florística selectivamente.

Cacería de mamíferos en la Zona de Uso Especial y de Amortiguamiento del Parque Nacional Tingo María, Huánuco, Perú
Authors: Gonzales Guillén Fiorella Nasha , Llerena Reátegui Gabriel
Published: December 2014

Entre los meses de agosto a noviembre del 2011 fueron llevadas a cabo 42 encuestas semi-estructuradas para evaluar la cacería de mamíferos en las zonas de uso especial (ZUE) y de amortiguamiento (ZA) del Parque Nacional de Tingo María. Los resultados indican que el 43% de la población practica la cacería como una actividad secundaria, siendo la principal la agricultura de minifundio. La metodología más utilizada para la cacería son las “tramperas” en tanto que la frecuencia de caza es de 2 a 3 veces al mes. La cacería es más frecuente después de la época húmeda, la misma que es selectiva y responde al sabor de la carne que a una necesidad económica. Entre los mamíferos más cazados figuran el añuje Dasyprocta sp. y el picuro Cuniculus paca, mientras que los animales de mayor biomasa como el sajino Pecari tajacu no son muy frecuentes en el área, por lo que se recomienda incrementar el control de la cacería de especies vulnerables en los caseríos que se encuentran dentro y en las inmediaciones del parque.
Yeast species in vulvovaginitis candidosa
Authors: Nemes-Nikodém Éva , Tamási Béla , Mihalik Noémi , Ostorházi Eszter
Published: December 2014

Introduction: Vulvovaginal candidiasis is the most common mycosis, however, the available information about antifungal susceptibilities of these yeasts is limited. Aim: To compare the gold standard fungal culture with a new molecular identification method and report the incidence of yeast species in vulvovaginitis candidosa. Method: The authors studied 370 yeasts isolated from vulvovaginal candidiasis and identified them by phenotypic and molecular methods. Results: The most common species was Candida albicans (85%), followed by Candida glabrata, and other Candida species. Conclusion: At present there are no recommendations for the evaluation of antifungal susceptibility of pathogenic fungal species occurring in vulvovaginal candidiasis and the natural antifungal resistance of the different species is known only. Matrix Assisted Laser Desorption Ionization Time of Flight identification can be used to differentiate the fluconazole resistant Candida dubliniensis and the sensitive Candida albicans strains. Orv.

Gingival Embrasure Fill In Fixed Implant-Supported Prosthetics: A Review
Authors: Flanagan Dennis
Published: December 2014

After provisional or definitive cementation of fixed implant-supported prostheses, spontaneous gingival proliferation may occur to fill the cervical embrasure areas of the prosthesis. Adequate oral hygiene, osseous spacing between the supporting implants and attached or immovable soft tissue may be the conditions that allow this phenomenon. This proliferation embrasure fill eliminates interproximal gingival voids, that is, black triangles, and makes the outcome more esthetically acceptable. Since interproximal prosthetic deign and implant positioning may be the primary factors for the fill, the gingival fill may be, in fact, an epulis.

Published: December 2014

This paper is a study on corporate communication and the ability to innovate in small businesses. The guiding question seeks to respond whether organizational communication is able to make progress and / or support innovation in micro and small companies, and the main objective is to analyze the relationship between innovation and organizational communication. It was applied the case study method and document research for interpreting a diagnosis instru- ment called “Innovation Radar” in a small business company located in the countryside of São Paulo state. The diagnosis is made based on assessment dimensions aimed at checking the maturity and the degree of innovation in micro and small companies. By evaluating these di- mensions it was possible to build analytical frameworks and highlight the influence of corporate communication in promoting innovation. The results indicate that every dimension of the “In- novation Radar” can improve their performance by means of corporate communication.

Ethical Behavior of the Classical Music Audience
Authors: Wilson Mary Katherine , Marczynski Sarah , O’Brien Elizabeth
Published: December 2014

The purpose of this research is to gain a better understanding of expected ethics of audience behavior during a classical music performance. Through a better understanding of cultural identities and practices of the classical music audience, symphony organizations may be able to more closely align audience expectations and the socialization frameworks that are present throughout the classical music experience. The researchers engaged in an ethnographic qualitative research approach in this study. Specific to this study, the researchers were engaging in gaining a greater understanding of classical music audience culture and how this may be impacting participants that are of a “marginalized” or nontraditional classical music audience group. There were 6 new-to-file ticket-buying patrons from the Chattanooga Symphony & Opera who participated in the study. The predominant theme that emerged from the focus group participants was that they like the traditional classical music experience, including venue, audience behavior expectation, and orchestration components, as it is. Further research is needed to better understand if these preferences root in long-standing structural and institutional frameworks that perpetuate cultural identities and practices and minimize audience “performance anxiety” because of reassurance of learned socialization processes (Jacobs, 2000; Mandeles, 1993). Or, if the American classical music audience of today authentically desires the concert etiquette and rituals that began in the 19th century European concert halls because the etiquette and rituals provide an ideal psychological setting for enjoyment of the classical music experience.
Changes in Kernel Filling with Selection for Grain Yield in a Maize Population
Authors: Eichenberger Steve , Miguez Fernando , Edwards Jode , Knapp Allen
Published: December 2014

Genetic improvement in kernel filling characteristics has been an important contributor to hybrid maize (Zea mays L.) yield increases. However, changes in kernel filling characteristics have not been evaluated within the context of recurrent selection programs. The objective of this study was to determine if rate and duration of kernel filling and their interaction with plant density changed with long‐term recurrent selection for agronomic performance in the Iowa Stiff Stalk Synthetic (BSSS) population. Populations selected for improved grain yield and agronomic performance were compared with the unselected base population, BSSS, at average final plant densities of 4.7 and 6.6 seeds m−2 at two locations near Ames, IA in 2009 and 2010. Treatments were replicated three times per location in a split plot design. Selected populations had a longer period of kernel filling but did not have a higher rate of kernel filling. Selected populations also had reduced final kernel weight at higher plant density, whereas unselected populations did not differ in final kernel weight. Reduction in final kernel weight at high plant density in selected populations suggests that increases in grain yield at high plant density in selected populations resulted from components of grain yield other than final kernel weight.

Published: December 2014

Russian wheat aphid (RWA, Diuraphis noxia, Mordvilko) biotype 2 (RWA2) is virulent to most known RWA resistance genes and severely threatens wheat (Triticum aestivum L.) production in the hard winter wheat area of the U.S. western Great Plains. We determined RWA2 reactions of 386 cultivars from China, 227 advanced breeding lines and recently released cultivars from the United States, 505 landraces from countries where RWA is endemic, and 31 genetic stocks developed in the United States, Australia, Canada, and Russia. The majority of wheat accessions from China and the United States were highly susceptible to RWA2. Only nine landrace accessions produced a homogeneous resistant reaction. In addition, highly resistant plants were identified in 28 heterogeneous landraces. Thus, reselection was conducted to purify some potential resistance sources, and the single‐plant progenies of 220 selected plants were evaluated. Homogeneous resistant or highly resistant lines were identified from seven previously heterogeneous landraces. Reselection line PI 626759‐20‐32 offered a high level of resistance similar to lines carrying Dn7, the rye (Secale cereale L.)‐derived resistance gene associated with undesirable bread‐making quality. PI 626759‐20‐32 has the potential to supplement or replace Dn7 as a new RWA2 resistance source in wheat breeding.

Published: December 2014

Aims:

The purpose of this study was assess the effect of a training session with Nintendo Wii® on the hemodynamic responses of healthy women not involved in regular physical exercise. Method: Twenty-five healthy unfit women aged 28 ± 6 years played for 10 minutes the game Free Run (Wii Fit Plus). The resting heart rate (RHR), systolic and diastolic blood pressures (SBP and DBP), and double (rate-pressure) product (DP) were measured before and after activity. The HR during the activity (exercise heart rate, EHR) was measured every minute.

Results:

A statistically significant difference was observed between the RHR (75 ± 9 bpm) and the mean EHR (176 ± 15 bpm) (P < 0.001). The EHR remained in the target zone for aerobic exercise until the fifth minute of activity, which coincided with the upper limit of the aerobic zone (80% heart rate reserve (HRR) + RHR) from the sixth to tenth minute. The initial (110 ± 8 mmHg) and final (145 ± 17 mmHg) SBP (P < 0.01) were significantly different, as were the initial (71 ± 8 mmHg) and final (79 ± 9 mmHg) DBP (P < 0.01). A statistically significant difference was observed between the pre- (8.233 ± 1.141 bpm-mmHg) and post-activity (25.590 ± 4.117 bpm-mmHg) DP (P < 0.01).

Conclusion:

Physical exercise while playing Free Run sufficed to trigger acute hemodynamic changes in healthy women who were not engaged in regular physical exercise.
A Scaling Model for Predicting the Gas-Channel Formation Period in Crater-Like Electrospinning of Nanofibers
Authors: Liu Jian , Zhang Lei , Liang Wei , Huang Dong-Wei , Liu Yong
Published: December 2014

Crater-like electrospinning is a novel and cost-effective method for the mass scale production of nanofibers.
The gas channel in the polymer solution plays a key role to produce a bubble Taylor cone or a crater-like Taylor cone,
which is the key to eject the thin fluid jets (finally solidified into nanofibers) in electrospinning process. However, the
formation mechanism of gas channel of crater-like Taylor cone is still unclear, which hinders further development of this
process. In this work, a simple and effective scaling model was firstly established to predict the period of the gas-channel
formation in the polymer solution during electrospinning process. Our theoretical analysis showed that the gas-channel
formation period was mainly determined by the input air pressure during the process. The relationship between the
formation period and the input air pressure followed a scaling law. In order to verify the model, crater-like electrospinning
process was carried out and a high-speed digital camera was employed to observe the gas channel. The experimental
results agree well with the scaling model, which indicates that the proposed system is feasible. The scaling model could be
useful in helping us to understand the process.

Published: December 2014

In this paper, the stress-related damping ratio formula of box girder with corrugated steel webs is introduced.
Using response spectrum method, an iterative algorithm is proposed to calculate the seismic response and the stress-related damping ratio under different seismic intensities. Based on a simply supported composite box girder bridge with
corrugated steel webs, the stress-related damping ratios are calculated under different seismic intensities through iteration.
The analysis and comparison show that the stress-related damping ratio increased with the seismic intensity, which is
smaller than 0.05 under the lower seismic fortification intensity, and larger than 0.05 under the higher seismic intensity.
Different damping ratios should be considered under different seismic intensities for the seismic response analysis of the
bridge.

This paper gives a mechanism design of a six DOF hydraulically actuated manipulator firstly. Then its DH
frames and link parameters are given. Next, its forward kinematic equations are derived according to homogeneous
transformation method. Fourthly, the analytical solutions of its inverse kinematics are solved by given the position and
posture of the end-effector simultaneously. The posture of the end-effector is given with three z-y-z Euler angles for they
have obvious geometry meanings and are easy to be measured. In addition, the correctness of the inverse kinematic
equations is verified in Simulink by comparing many sets of randomly produced joint variables in workspace and their
corresponding inverse solutions.
