Forced plumes

This paper describes an investigation of the turbulent forced plumes generated by steady release of mass, momentum and buoyancy from a source situated in an extensive region of uniform or stably stratified fluid. The treatment, which is an extension of earlier work on buoyant plumes, also brings out the relationship between the jet and the Plume as special cases of forced plumes. The analysis shows that the behaviour of a forced plume from a source of finite size which delivers buoyancy, mass and momentum can in a uniform environment be related to that from a virtual point source of buoyancy and momentum only, and a treatment is given for the latter type of forced plume. When the environment is weakly stratified it is inferred that forced plumes can be related to point definitely; but when the environment is stably stratified, increasing the release of mass and momentum from a given source of buoyancy has the effect at first of reducing the total height of the plume, and only for very large flux of momentum does the height increase again, without limit. A description is given for the behaviour of vertical jets in a stably stratified environment, and for forced plumes of fluid with negative buoyancy.
Neutrophil to lymphocyte ratio correlate with syntax score in patients with non st elevation acute coronary syndrome

Introduction: In this study we aimed to investigate the correlation between the neutrophil to lymphocyte ratio (NLR) and severity of coronary artery disease (CAD) in patients with Non ST elevation acute Coronary Syndrome (NSTE-ACS) using the SYNTAX score (SXscore). Method: A total of 150 patients with NSTE-ACS who underwent coronary angiography were enrolled in the study. NLR was measured for all patients at presentation. The study population was then divided into 3 tertiles based on the SYNTAX trial results (1). The low syntax group (n = 25) was defined as those with an SXscore ≤ 22, the intermediate syntax group (n = 78) was defined as an SXscore ≥ 23 and < 33, and the high syntax group (n = 47) as those with an SXscore ≥ 33. Result: NLR was significantly lower in patients with a low SXscore compared to patients with an intermediate SXscore or high SXscore (2.4 ± 2 to 4.8 ± 2 and 6.9 ± 3, P < 0.001). Linear regression analysis revealed that NLR (coefficient β = 0.470, 95%CI: 1.273-1.935, P < 0.001) was significantly associated with the SXscore in patients with NSTE-ACS. Conclusion: Our results indicate that NLR is independently associated with the severity of CAD in patients with NSTE-ACS.
The Usage of Social Media in New Product Development Process: The Benefits and the Challenges

This chapter contributes to a better understanding of the role of social media in the NPD process and a debate about the impact of social media on NPD success. Through a critical literature review, this chapter provides an insight into the impact of social media on incremental NPD and its contribution to NPD success, in the context of customer involvement. The review is mainly derived from 286 relevant papers published in top-ranked journals between 2005 and 2014. The results suggest that while social media provides an effective and efficient method for collecting information and knowledge about customers' expectations and experiences, it does not necessarily always lead to NPD success. The study shows that hidden customer needs, an advanced evaluation tool, the huge amount of information and a firm's absorptive capacity challenge the use of social media.
The Johns Hopkins University Studies in Geology

before mentioned, the older tin-bearing alluvium : this must not te confused with the Tertiary volcanic series, comprising many ash cones and necks and flows of olivine-basalt. This formation also gives rise to deep leads by burying old valleys. The Bulletin is excellently illustrated by photographs of local scenery and microphotographs of rocks, and is accompanied by a well-printed coloured geological map on the scale of half an inch to the mile.
Towards DevOps: Practices and Patterns from the Portuguese Startup Scene

The DevOps movement aims to facilitate the work of both Developers and Operators by creating a new culture of collaboration between the two as well as introducing new practices and methodologies. With initial discussions going back as far as 2008/2009, ideas regarding the DevOps movement and what it means are still evolving and, eight years later, are still topics of discussion even within the community. Combining that with the fact that some studies are showing a significant number of companies adopting DevOps and an equal amount looking into doing the same, it becomes worrying that DevOps literature is still largely based on personal opinions rather than scientific or academic literature. This thesis represents a step toward a better and broader understanding, within the scientific community, of DevOps and its practices. With the objective of enabling more businesses to adopt DevOps and do so with less uncertainty we identify, in this thesis, 13 DevOps related patterns extracted from 25 Portuguese startup companies. Then, we conclude that the progress made with this thesis should be extended and we point out the direction to do so.
STRESS ANALYSIS OF ECCENTRIC RINGS IN BIPOLAR COORDINATE SYSTEM

Stress analysis of eccentric ring is carried out in bipolar coordinate system under uniform internal and external pressure. Airy stress function is chosen in such a way that it satisfies the bi-harmonic equations and boundary conditions in bipolar coordinate system. Stresses are obtained for various parameters such as eccentricity, various inner radius to outer radius ratios. Effect of eccentricity is investigated on the stresses of the eccentric rings. Results are useful for the design of eccentric rings.

Study on the Importance of Knowledge, Innovation and Entrepreneurship on the Country’s Progress

Entrepreneurship as a term has become a well-known term around the world, where the society sees the entrepreneurs connected with the well-being and economic development of any country. In the same time, the importance of innovation has been highlighted many times but little has been said about the major source of entrepreneurial opportunities that potentially can arise from that innovation idea. This research focuses on the role of knowledge in creating opportunities that can be exploited through innovation and possibly with some future entrepreneurial step. We would analyse the theoretical models of growth vis-a-vis the link between the knowledge, innovation and entrepreneurship. Also we will try to comprehend the forces of knowledge and how innovation and entrepreneurs make it marketable and help the growth process.
Do Resale Royalties Make Artists Better O? An Economic Analysis of a New EU Directive

According to a new directive of the European Union, artists are entitled to a share of the price if their pieces of work are resold. The principal aim of this initiative is to let the artists participate in the economic success of their work. Our analysis shows that the new directive is most likely to make the artists worse o�. This holds in particular if expert dealers are able to distinguish good from less talented artist. In this case, the more talented artists are most likely to loose. The analysis of the relation between the artist and his dealer as an incentive compatible contract leads to further objections against the new EU directive. However, the paper also points out under which conditions a resale royalty at least is an incentive compatible contract. JEL-ClassiÞcation: K 11
CMOS device scaling beyond 100 nm

CMOS device scaling beyond 100 nm has been investigated. Issues on scaling and previous works to solve them were reviewed. Super steep retrograde channel formation using selective epitaxial growth of undoped silicon effectively suppressed short channel effect and improved transconductance. The stack gate dielectrics of oxynitride and nitride suppressed boron penetration and improved drive currents. Transistor characteristics and reliability issues on gate oxide scaling were investigated in the regime of large gate leakage currents. High performance CMOS transistors of L/sub gate/=70 nm and T/sub ox/=1.4 nm were fabricated, which showed current drives of 860 /spl mu/A//spl mu/m (NMOS) and 350 /spl mu/A//spl mu/m (PMOS) at I/sub off/=10 nA//spl mu/m and V/sub dd/=1.2 V.
Control of power quality in inverter-based distributed generation

Power quality is an important additional service of inverter-based interfaces for distributed generators. In grid connected applications the power quality depends on the harmonic content of the current injected at the point of common coupling. By careful design of the power converter and its output filter the switching frequency components in the output current spectrum can be reduced to low levels. The effect of the harmonic distortion of the grid voltage on the output current can be minimised by using an appropriate inverter control strategy. Conventional control methods (manipulation of inverter voltage magnitude and phase) offer active and reactive power control, but not the control of the output current quality. This paper describes a new choice of control structure and explains the interaction between the applied control loops. The inverter is used to control the current in the first element of an LCL filter. A further controller is wrapped around this loop to control power export to the grid. The usefulness of this arrangement in providing big power quality is emphasised. Experimental results from a 10 kVA prototype are used to evaluate the distortion rejection properties and the regulation of active and reactive power control. The results show high quality of generated power and excellent transient and steady state-response to both active and reactive power demands.
ВОЗМОЖНОСТИ СОВРЕМЕННЫХ КЛЕТОЧНЫХ ТЕХНОЛОГИЙ ДЛЯ ВОССТАНОВЛЕНИЯ ПОВРЕЖДЕНОГО СУСТАВНОГО ХРЯЩА (АНАЛИТИЧЕСКИЙ ОБЗОР ЛИТЕРАТУРЫ)

Despite a wide variety of surgical procedures utilized in clinical practice for treatment of articular cartilage lesions, the search for other options of articular reconstruction remains a relevant and open issue at the current stage of medicine and biotechnologies development. The recent years demonstrated a strong belief in cellular methods of hyaline cartilage repair such as implantation of autologous chondrocytes (ACI) or cultures of mesenchymal stem cells (MSC) including techniques for genetic modification of cells. The purpose of presented review is to summarize the published scientific data on up to date results of perspective cellular technologies for articular cartilage repair that are being developed. Autologous chondrocyte transplantation originally performed by Swedish researchers in 1987 is considered the first clinically applied technique for restoration of hyaline cartilage using cellular technologies. However, the transplanted cell culture featured low proliferative capacity and inability to form a regenerate resistant to high physical activity. Another generation of methods originated at the turn of the century utilized mesenchymal stem cells instead of autologous chondrocytes. Preparation of MSCs is a less invasive procedure compared to chondrocytes harvesting and the culture is featured by a higher proliferative ability. Researchers use various biodegradable carriers (matrices) to secure cell fixation. Despite good clinical mid-term outcomes the transplanted tissue-engineering structures deteriorate with time due to cellular de-differentiation. Next generation of techniques being currently under pre-clinical studies is featured by the preliminary chondrogenic modification of transplanted cell culture. Usage of various growth factors, modified cell product and gene-activated matrices allow to gain a stable regulatory and key proteins synthesis and achieve a focused influence on regenerate's chondrogenic proliferation and in result to form a good hyaline cartilage resistant to high physical load in long term period. Thus, development of methods for articular cartilage repair has long ago went beyond the interests of clinical physicians, and only the close interdisciplinary cooperation of clinicians and specialists for cytology, molecular genetics and, probably, virology would enable replacement of a defect with a rigorous hyaline cartilage.
Quadruple Cropping Patterns in Bangladesh: Scope and Limitations

Growing crops in a piece of land influence soil fertility depending on adopted management practices and intensity of cropping. Farmers in many cases do not use balanced fertilizers because of socio-economic conditions and thus nutrient mining is inevitable. We hypothesize that soil degradation is likely along with reduced crop productivity in future with researcher proposed four crops production packages. Semi-structured questionnaire, and IDRISI3.2 were used for data collection and mapping, respectively. Net quadruple cropped areas were about 7.09%. Soil fertility scores of those areas were 40–50 and above 50, covering about 4.56% and 3.66%, respectively of the net cropped areas indicating medium fertility status. Apparent nutrient balances for nitrogen, phosphorus, potassium, sulfur, calcium, magnesium and silicon were negative with researcher's introduced cropping patterns and fertilizer management compared to existing patterns. Zinc with all introduced cropping patterns and boron with Potato–Boro–T Aus–T Aman pattern are increasing but other micro nutrients are diminishing. Phosphorus and Sulfur build ups are taking place under farmer's practice in Mustard–Boro–T Aman, Potato–Boro–T Aman and Boro–Fallow–T Aman patterns. Zinc build up is taking place under farmer's managed cropping patterns; but iron, copper, boron, molybdenum and chloride are deteriorating from the soils. These indicate that growing four crops in a year with existing fertilizer recommendations are not sustainable in terms of soil fertility. Adoption of such intensive crop culture by the majority of the farmers is unlikely except in some sporadic areas having market driven economy of vegetable cultivation.
miR-9-5p promotes myogenic differentiation via the Dlx3/Myf5 axis

MicroRNAs play an important role in myogenic differentiation, they bind to target genes and regulate muscle formation. We previously found that miR-9-5p, which is related to bone formation, was increased over time during the process of myogenic differentiation. However, the mechanism by which miR-9-5p regulates myogenic differentiation remains largely unknown. In the present study, we first examined myotube formation and miR-9-5p, myogenesis-related genes including Dlx3, Myod1, Mef2c, Desmin, MyoG and Myf5 expression under myogenic induction. Then, we detected the expression of myogenic transcription factors after overexpression or knockdown of miR-9-5p or Dlx3 in the mouse premyoblast cell line C2C12 by qPCR, western blot and myotube formation under myogenic induction. A luciferase assay was performed to confirm the regulatory relationships between not only miR-9-5p and Dlx3 but also Dlx3 and its downstream gene, Myf5, which is an essential transcription factor of myogenic differentiation. The results showed that miR-9-5p promoted myogenic differentiation by increasing myogenic transcription factor expression and promoting myotube formation, but Dlx3 exerted the opposite effect. Moreover, the luciferase assay showed that miR-9-5p bound to the 3’UTR of Dlx3 and downregulated Dlx3 expression. Dlx3 in turn suppressed Myf5 expression by binding to the Myf5 promoter, ultimately inhibiting the process of myogenic differentiation. In conclusion, the miR-9-5p/Dlx3/Myf5 axis is a novel pathway for the regulation of myogenic differentiation, and can be a potential target to treat the diseases related to muscle dysfunction.

Developing methods for measuring pedestrian accessibility

Accessibility measures and indicators are useful in helping to identify social groups and locations with poor levels of access to services and facilities. These measures however have not been directly linked to transport policies within the accessibility planning tools widely used in the UK. To help do this, a GIS based tool, AMELIA is being developed. Many macro level policies can fail at the micro level. For example, strategic policies to help address accessibility of wheel chaired people may fail when difficulties faced by them are very micro such as the obstacles on the pavement. Issues relating to assumptions, scale and sensitivity with existing pedestrian accessibility measures and lack of micro-level data availability are discussed. Some methods for measuring pedestrian accessibility are presented and analyzed by setting up a detailed street level database. These will be taken into account in designing AMELIA.
Ocular Syphilis Mimicking Giant Cell Arteritis

Syphilis is a rare cause of vision loss that mostly occurs after an infection of the meninges, brain tissue, and parenchyma. Syphilis can mimic auto-immune disease like giant cell arteritis which also manifest as sudden vision loss. Spirochete Treponema pallidum can spread through sexual contact and cause painless ulcers. Spirochetes can disseminate systemically and lead to secondary syphilis. Ocular syphilis can affect all parts of the eye in secondary and tertiary stages. It can present as scleritis, inflammation of the optic nerve, and uveitis. We present the case of a 59- year-old male suffering from severe vision loss in the left eye and headache initially misdiagnosed with giant cell arteritis. He was correctly diagnosed with ocular syphilis after seeing a red macular rash on palms and soles, and was given penicillin G and probenecid. His visual acuity and field of vision improved soon. Ocular syphilis is usually diagnosed late or misdiagnosed and leads to irreversible vision loss. Physicians should keep in mind the possibility of ocular syphilis in patients presenting with a sudden loss of vision and severe headaches.
A novel temperature-responsive mixed matrix ultrafiltration membrane based on boron nitride nanomaterial

A novel mixed matrix membrane was prepared by blending polysulfone with two-dimensional boron nitride followed by its hydroxyl functionalization. Prepared nanocomposite membranes were characterized for the surface morphology, surface roughness, zeta potential and hydrophilicity. Uniform dispersion of boron nitride nanoparticles in polysulfone matrix and consequent changes in membrane properties were confirmed by scanning electron microscope images, atomic force microscope images, zeta potential, contact angle analysis, and X-Ray photoelectron spectroscopy. Differential scanning calorimetry (DSC) technique was used to determine the glass transition temperature (Tg) of the modified membrane and the results revealed the presence of BN in the membrane matrix. The highest water flux of 329.52 Liters per sqm per hour (LMH) was obtained in case of PS/BN (1%) as compared to 151.87 LMH of virgin membrane and Albumin rejection also increased by nanocomposites membranes up to certain concentration of Boron nitride. A unique behavior of temperature responsiveness of nanocomposite membrane was observed, where a steep increment in permeate flux by 205% at higher temperature was noted as compared to the virgin Polysulfone membrane where only 103% increase was recorded for the same temperature range. Moreover, the water uptake capacity of nanocomposite membranes were measured to understand the changes with nanomaterial incorporation. The membrane showed a good promise for high-temperature separation applications.
Shouting in the Kenyan Space: Can Spaceteam ESL Improve L2 Learners’ Oral Reading Fluency?

This study examined the effects of Spaceteam ESL, a digital shouting game, on the development of oral reading fluency (ORF) among 71 English as a second language (ESL) students in three primary and secondary schools in Mombasa, Kenya. Following a mixed-methods approach for data collection and analysis, we pre-tested and post-tested the participants on their ability to read aloud efficiently (speed) and accurately (accuracy) in three tasks: (1) phrases extracted from the game; (2) phrases not related to the game; and (3) a short anecdote. Paired-samples t-tests results revealed that, as hypothesized, participants who played Spaceteam ESL improved their ORF on measures of speed on all tasks, possibly because of the fast-paced nature of the game. However, no significant differences were observed in terms of accuracy due to a ceiling effect: the participants had already mastered the intricacies of the letter-to-sound rules of English orthography. Overall, these findings corroborate our hypothesis that some of the affordances of Spaceteam ESL (e.g., focus on speed reading, multiple and varied opportunities for practice) could contribute to the development of some aspects of oral reading fluency.
Relationship Between Road Traffic Exposure and Human Health

Hong Kong is highly urbanised and a substantial proportion of the population lives within proximity to the roadside. The association between long-term exposure to road traffic air pollution and risks to human health has attracted much research attention in western countries but perhaps not enough in Hong Kong, although they have been lobbying topics favoured by environmentalists. This study relates the pulmonary function of samples to the living air quality. The study focuses on five residential areas and five business areas in Hong Kong. Samples are required to take a pulmonary function test. Air pollutants PM2.5, PM10, CO2 and CO were monitored as well. Statistical regression was further applied to quantify the significant contributors to pulmonary function. This study showed that the pulmonary function in terms of FVC has a significant difference in different areas. The samples that lived in heavy traffic areas had relatively poor value in terms of FVC. Last but not least, a statistical regression model was conducted and showed that PM10 and CO have a significant negative impact on lung function. This result raises the alarm about high-density town planning and also expresses the importance of promoting electric vehicles in Hong Kong.
