EFFECT OF PARTICULATE MATTER ON THE SULPHATION OF CALCAREOUS STONE IN HUMID ATMOSPHERE CONTAINING SULPHUR DIOXIDE

Effects of particulate matter on the decomposition of calcium carbonate with so2 has been examined by the laboratory simulation experiments. Some clay minerals, active carbon, metal oxides and chlorides which may represent the particulate matter in the polluted atmosphere have been used as impurity in the pure calcium carbonate matrix. Decomposition reactions were followed by quantitative determination of reaction products by FTIR and by weight increase of samples. The morphology of the samples have also been examined by using scanning electron microscopy. Experimental results reveal that calcium sulphite hemihydrate is the main reaction product of the calcium carbonate sulphation. It turns out that, the presence of particulate matter does not significantly change the extent of sulphation but it has considerable accelerating effect on the oxidation of calcium sulphite hemihydrate into gypsum.
PR ] 2 6 Ju n 20 19 Correlators of Polynomial Processes

A process is polynomial if its extended generator maps any polynomial to a polynomial of equal or lower degree. Then its conditional moments can be calculated in closed form, up to the computation of the exponential of the so-called generator matrix. In this article, we provide an explicit formula to the problem of computing correlators, that is, computing the expected value of moments of the process at different time points along its path. The strength of our formula is that it only involves linear combinations of the exponential of the generator matrix, as in the one-dimensional case. The framework developed allows then for easy-to-implement solutions when it comes to financial pricing, such as for path-dependent options or in a stochastic volatility models context.
EFFECT OF COMBINATION OF YANYU TONGLUO PLASTER AND CELECOXIB CAPSULE ON TREATMENT OF KNEE OSTEOARTHRITIS

Knee osteoarthritis is the main cause of knee pain in the aged. A survey has shown that the incidence of knee osteoarthritis in men and women are 24.7% and 54.6%, respectively, and it increases with age, resulting in a heavy social burden. Presently, there are no specific and effective orthodox methods for treating knee osteoarthritis. However, it is claimed that plasters from traditional Chinese medicine (TCM) have unique advantages in the treatment of the disease. In this study, the clinical effect of Yanyu tongluo plaster on knee osteoarthritis and its potential mechanism were investigated.
Immune Thrombocytopenia among Children Living at a High Altitude Region : A Hospital-Based Retrospective Study

Objective: To identity the pattern of immune thrombocytopenia (ITP) and to describe presenting features, laboratory characteristics and outcome of the ITP among Saudi children living at a high altitude area. Methodology: A retrospective descriptive study design was followed at the Pediatric Medical Department of Aseer Central Hospital, during the period from January 2011 till December 2013. All data of children aged 6 months till 12 years with the diagnosis of ITP during the study period (n=46) were included into this study. Results: More than half of patients were females (58.7%). Most of them were diagnosed before the age of 6 years (86.9%). More than half of patients had their ITP attack after infection (58.7%). Only one patient had positive family history (2.2%). The most common symptoms were skin rash (93.5%) and epistaxis (41.3%), which was significantly more among male children. The most common signs were ecchymosis (87%), purpura (76.1%), petechial rash (60.9%), bleeding in mucous membranes (58.7%) and pallor (32.6%). Splenomegaly was present in 6.5% of patients. Platelet count of most children (80.4%) was less than 20x10 /ml, 37% had low hemoglobin level (5-12gm/dL). ESR was >30mm/hour in almost one fourth of patients. Peripheral blood smears showed isolated thrombocytopenia in 82.6% of patients, megakaryocytes in 15.2% and pancytopenia in 2.2% of patients. Bone marrow aspiration was performed for 28 cases (60.9%) to confirm diagnosis (50%), to start steroids treatment (4.3%), for pancytopenia (4.3%) or splenomegaly (2.2%). On discharge, the condition of 63% of children with ITP was completely resolved, with a higher cure rate among boys than girls (84.1% and 48.1%, respectively), 34.8% had chronic ITP, with a lower proportion among boys than girls (15.8% and 48.1%, respectively). One child died (2.2%), who was a girl. Differences between male and female children with ITP regarding their outcome at discharge were statistically significant (p=0.042). Conclusions: There are higher predilection of ITP and significantly lower cure rates among girls than boys. These findings need further epidemiological, biochemical and hematological studies to be explained.

Intravenous thrombolysis improves one-year outcomes in mild stroke patients

The aim of this study was to evaluate the benefits and risks of intravenous thrombolysis (IVT) in patients with mild strokes after a period of one year. Mild symptoms were defined as an NIHSS score of ≤ 5 points on arrival, in accordance with most prior studies. Between March 2013 and December 2014, 763 consecutive patients diagnosed with acute cerebral ischemia were retrospectively enrolled in this study. Eventually, 240 patients met the eligibility criteria. Of these, 90 patients received IVT and 150 patients did not. Baseline characteristics and outcomes were collected at 3 and 12 months. Multivariable logistic analysis was employed. Patients treated with recombinant tissue plasminogen activator (rt-PA) had higher NIHSS scores on arrival, compared with those that did not receive rtPA (5 and 2, IQR 4-5 and 1-3, respectively; P < 0.001). IVT was independently associated with favorable outcomes at 3 months (OR 7.63, 95% CI 2.82 to 20.64; P < 0.001). At 12 months, the effects of IVT on favorable outcomes were maintained (OR 8.04, 95% CI 2.85 to 22.64; P < 0.001). Recurrent strokes were more frequent in patients without rt-PA treatment, but IVT did not significantly affect rates of recurrent strokes at either 3 or 12 months. No cases of symptomatic intracranial hemorrhaging were detected. Present results suggest long-term benefits from IVT for mild ischemic strokes, with a low risk of symptomatic intracranial hemorrhaging. In conclusion, IVT is recommended for patients with mild strokes.
LINKING THE WEATHER TO GLACIER HYDROLOGY AND MASS BALANCE AT PEYTO

Attempts have been made to link weather variations at Peyto Glacier to mass balance fluctuations. On the larger scale of inquiry, associations have been found between seasonal components of the mass balance and synoptic weather types. Also, there are significant correlations with temperature and precipitation records from regional weather stations. The smaller scale of study features micro-meteorological investigations to document the energy components of summer ablation and surface meltwater generation. Field measurements of the energy exchange components in summer show that solar short-wave radiation and atmospheric long-wave radiation supply the glacier surface with approximately 16 and 25 MJ m-2 of energy per day respectively, thus constituting important heat sources for the melting of ice and snow. Over snow, the reduction of net long-wave radiation loss by cloud cover may speed up the retreat of the snowline, thus preparing the glacier for high levels of meltwater production later in the season. Turbulent transfer of sensible heat from air to ice is a significant energy source, contributing 3 to 4 MJ m-2 to the daily melt. It is strongly controlled by Munro Linking the weather 135 PEYTO GLACIER ONE CENTURY OF SCIENCE katabatic wind flow, which is best developed in fair, anticyclonic weather. Latent heat exchange due to turbulent water vapour transfer is only a minor component of the surface energy exchange picture, supplying less than 0.5 MJ m-2 to melting. The cooling effect of turbulent heat loss to the glacier may be felt for at least 20 m above the glacier surface. The conversion of melt energy data into ablation estimates yields reasonably accurate results for ice, where values range from -1 to 8 mm h-1 of water equivalent ice melt. Negative estimates, and a tendency to overestimate ablation at the higher end of the range, are signs of weathering crust development. Less success is achieved over snow because of its variable density structure. The energy balance approach works sufficiently well over glacier ice and snow to constitute the basis of a modelling scheme for both the ablation phase and the accumulation phase of the mass balance cycle. Surface energy exchange, acting in consort with the precipitation regime, is thus seen to be the essential link between weather variations and mass balance fluctuations.
Experimental Study on Injection-induced Fracture Propagation and Coalescence for EGS Stimulation

Shear slip has been recognized as a dominant mechanism of permeability enhancement during the hydraulic stimulation in engineered geothermal systems (EGS). The so-called “hydroshearing” process usually occurs at treatment pressures below the minimum principal stress, and reactivates pre-existing fractures causing them to slip and dilate and possibly propagate in the shear and tensile modes creating new cracks. These processes can result in generation of a network with increased permeability for economic flow rates. We have performed injection experiments to investigate the possibility of flow rate increase through the propagation and coalescence of pre-existing fractures in granites under triaxial conditions. Results show that the pre-existing fractures can be propagated and coalesce at treatment pressures lower than the minimum principal stress during water injection. Also significant flow rate increase can be achieved through the fracture network generation caused by pre-existing fractures propagation and coalescence. In addition, both tensile wing cracks, shear and/or mixed-mode propagated secondary cracks can form. These observations show that the so called “hydroshearing” involves both shear slip and fracture propagation and contribute to the shear stimulation in EGS.
Studies in Dictionary Use: Recent Developments

Empirical study of dictionary use is now almost one hundred years old, if we count Grinstead (1915) as the first paper in this category. Obviously, a larger part of the long period saw very little research activity, as the majority of the empirical user studies available today have been done in the last two decades or so (for a recent survey, see Welker 2010). Several authors have pointed out the methodological shortcomings of some of those studies (e.g. Hulstijn and Atkins 1998; Dolezal and McCreary 1999; Humble 2001; Lew 2004; Tarp 2009), but there is no denying that the methodological standards are improving at a steady rate. International Journal of Lexicography has given some attention to empirical user studies. Over the last ten years, eleven such articles can be identified; however, as many as four of these have been published in the last two years (Chon 2009; Lew and Doroszewska 2009; Chen 2010; Dziemianko 2010). This could suggest that interest in this strand of research is on the rise, and so it was thought that the lexicographic community would welcome a collection of reports on original user studies presented under a single cover. As a result of an effort to produce such a collection, the present issue includes six state-of-the-art contributions. Most experts now agree that dictionaries should be compiled with the users’ needs foremost in mind. We are also now well aware of how varied those needs can be. In view of this, it is surprising that very few studies actually address this point directly and in sufficient detail. The first paper in this volume, Do dictionaries define on the level of their target users? A case study for three Dutch dictionaries, written by Gilles-Maurice de Schryver and Danie Prinsloo, provides a model for such investigations. The authors examine whether three different definition formats as used in three Van Dale dictionaries for native speakers of three different age brackets really work best for users of the intended age range. The answer is a qualified no. It appears that the publisher has systematically overestimated the metalinguistic skills of the users at just about any age. Collocation is an area that has long been neglected by lexicography and language learning alike. Batia Laufer’s piece (The contribution of dictionary use to the production and retention of collocations in a second language) looks at collocation from both these angles by examining the use and acquisition of International Journal of Lexicography, Vol. 24 No. 1, 2011, pp. 1–4 doi:10.1093/ijl/ecq044 Advance access publication 27 January 2011 1
Particulate matter accumulation – further differences between native Prunus padus and non-native P

Particulate matter (PM) is one of the most harmful inhaled pollutants. Where pollutants have been emitted into the atmosphere, the most effective method for cleaning the air is through phytoremediation, whereby plants act as biological filters. PM has a negative impact on plants, but knowledge of PM effects on the photosynthetic apparatus is limited. In European forests, species of the genus Prunus L. play a key role in the composition of the forest understory and urban as well as industrial plantings. Shrubs of the native P. padus L. and closely-related invasive alien P. serotina Ehrh. are particularly widespread. Thus, both are good model species in which to study the impact of PM pollution. The aim of this study was to assess the accumulation of PM in the context of leaf morphology and amount of epicuticular waxes on foliage, and the efficiency of the photosynthetic apparatus of P. padus and P. serotina. The study was conducted under controlled conditions using two variants of dust, cement and roadside PM. In addition, we analyzed the absorption of dust by leaves dividing it into three fractions by size (10−100 μm, 2.5−10 μm and 0.2−2.5 μm). Results showed that both P. padus and P. serotina accumulate PM mostly on the surface of their leaves (SPM), rather than in the wax layer (WPM). P. padus accumulated higher amounts of PM than did P. serotina. The higher presence of PM on leaves of P. padus resulted in a reduction of the efficiency of the photosynthetic apparatus, manifested by lower rates of photosynthesis and chlorophyll a fluorescence, coinciding with an increased stomatal resistance. A strong negative correlation was found between the amount of PM accumulation and the efficiency of the photosynthetic apparatus in P. padus, but not in P. serotina. We have concluded that alien P. serotina is more tolerant to the conditions of stress caused by PM pollution than is the native P. padus, which may partly explain its success in the invasion in Europe.
Passive acoustic monitoring of whale distribution in the Faroe-Shetland Channel

Results from previous surveys suggest that an area of the north-east Atlantic, the Faroe Shetland Channel is important for cetaceans. This study utilised passive acoustic survey techniques to evaluate the density of sperm whales in the Faroe Shetland Channel. Two-week surveys were carried out during oceanographic cruises in May and October 2001 and May 2002. A two hydrophone array was towed behind the vessel throughout the majority of the survey routes and was monitored by a two person team and by software designed to automatically detect and measure bearings to whales. Distances of individual sperm whales from the trackline were determined using target motion analysis. To calculate the density of whales during surveys we applied standard line transect techniques. The effects of sea conditions and survey vessel on our ability to detect whales were tested; the encounter rate and effective strip-width (esw) were estimated independently for each sea state and for each of the vessels. A total of 79 individual whales were detected, and their distances from the trackline were calculated. As a probable result of insufficient sample size and a small effects size, neither the esw nor the encounter rates varied significantly with sea state or between the two survey vessels. The density of sperm whales during each of the surveys was estimated to be 2.05, 0.52 and 1.75 whales per 1000km for the May 2001, October 2001 and May 2002 surveys respectively. Sperm whales were distributed across the majority of the Faroe Shetland Channel. This study has provided the basis for meaningful hypothesis generation in future studies and to gain a better understanding of the factors underlying the spatial and temporal distribution patterns of sperm whales in this area, data on oceanographic, biological and anthropogenic determinants should now be examined.
Organizational Commitment in the Canadian Armed Forces : The Mediating Role of Person – Organization Fit

2 Correspondence to: Irina Goldenberg, Defence Research & Development Canada/Chief of Military Personnel, Canada. Email: IRINA.GOLDENBERG@forces.gc. ca Abstract High quality leadership and support from the organization are two well-established factors that influence an individual’s commitment to their organization. However, very little is known about the processes through which these variables influence commitment. This empirical study drew on theory and research to propose person– organization (P–O) fit as a mediating variable to explain these relationships. A sample of 6,503 personnel in the Canadian Armed Forces provided responses to a personnel survey. Results indicated that P–O fit fully mediated the relationship between leadership satisfaction and organizational commitment and partially mediated the relationship between perceived organizational support and organizational commitment. These results contribute to the extant literature and theory by testing these relationships in a military context and by demonstrating the importance of P–O fit as a mediator of leadership, support, and organizational commitment. The results and their implications are discussed with particular emphasis on their importance in a military environment.
Clinical analysis of vertebroplasty in the treatment of vertebral compression fractures

Objective: To evaluate the clinical efficacy and influencing factors of vertebroplasty with high viscosity bone cement in the treatment of vertebral compression fractures. Methods: A total of 120 elderly patients with osteopenia and osteoporotic vertebral compression fractures were enrolled in this study. They were grouped according to the surgical site and bone mineral density, and underwent vertebroplasty with high-viscosity bone cement. After operation, the dispersion range of bone cement was delineated by stratification based on Computed Tomography (CT), on which the dispersion volume of bone cement was calculated; injection volume of bone cement was recorded; postoperative vertebral height recovery and correction degree of kyphotic Cobb angle were calculated, on which pain visual analogue scale (VAS) and Oswestry disability index (ODI) of the patients were evaluated before and after operation. Furthermore, postoperative vertebral height recovery and correction degree of kyphotic Cobb angle were compared between the patients with different surgical sites and different bone mineral density; correlation between the injection volume, dispersion volume of bone cement and the vertebral height recovery was analyzed. Results: Postoperative VAS and ODI of the patients in various groups were significantly lower than those before operation. The fractured vertebral height recovery was not correlated with the injection volume of bone cement (R2=0.004, P=0.487), but positively correlated with the dispersion degree of bone cement (R2=0.619, P=0.000). Conclusion: For the patients with different fracture sites and different bone mineral density, vertebroplasty with high viscosity bone cement can effectively correct the kyphotic Cobb angle and recover the injured vertebral height in the treatment of vertebral compression fractures as well as relieve the patient pain quickly and effectively and improve their quality of life.
GHGT-12 Effective confining stress depending on fluid flow and capillary sealing properties of mudstones for CO 2 geological sequestration

In this study, we investigated effective pressure of dependence on hydraulic properties (i.e. threshold pressure and permeability) of Kazusa group mudstones, which is taken from Boso peninsula in Japan, at 40°C and effective pressures up to 20 MPa. Additionally, to assess a correlation between these properties, a porosity change depending on effective stress is also examined. Our results demonstrates that for mudstones tested, the relationship between threshold pressure and permeability depends strongly on changes in pore structures as a function of effective pressure. © 2013 The Authors.

Rayleigh fading compensation method for 16QAM in digital land mobile radio channels

The authors propose a novel Rayleigh fading compensation method for 16 quadrature amplitude modulation (16QAM). The optimum parameters for 16QAM with a transmission rate of 16 k symbol/s, the BER (bit error rate) performance, and the interference performance are determined by computer simulation. It is shown that second-order interpolation is suitable for the fading compensation method. In the case of 16 k-symbol/s transmission, the optimum frame length is 16 symbols. The degradation due to the proposed fading compensation method is about 2 dB. The BER performance under Rayleigh fading environments at f/sub d/<100 Hz is in good agreement with the theoretical value. The BER performance degradation of the implemented 16QAM modem from the simulated results is only about 1 dB. These results confirm that a 16QAM modem using the proposed method can be applied to land mobile communications. <<ETX>>
How Consumers Process Unhealthy Food Advertising Featuring Risk-avoidance Appeals : Moderating Roles of Dieting Status and Gender on the Prediction Model of Self-and Functional Congruity

This study examined how the effects of risk-avoidance appeals in unhealthy food advertising are differently predicted by consumers’ selfand functional congruity. In addition, this research explored whether the predictive effects are moderated by consumers’ current dieting status and physiological gender. An experimental study found that functional-congruity had stronger predictive effects on ad evaluations than self-congruity. Moreover, the risk-avoidance appeals in unhealthy food advertising are more cognitively processed by dieting consumers, as well as among female consumers. These results provide several theoretical and practical implications for public health policy officials.
Extension of Fisher's Classical Result on Exponential Dynamics of the Reproductive Value to a Wide Class of Populations

The classical result by R.A. Fisher concerning reproductive value dynamics is expanded to the case of varying vital rates with a constant cohort Lotka’s r. Based on the demographic potential approach, generalization of the concept of reproductive value is introduced, which exhibits exponential dynamics both in the classical case of constant vital rates and in a wider class of populations. The generalized reproductive value introduced in the paper fits the classical interpretation by R.A. Fisher as a discounted sum of future births in the general class of models addressed in the paper. Results could be of importance for estimating the fitness of biological populations, aggregate population modeling, and studying the long-term consequences of varying vital rates.
