Application of FTIR spectroscopy to assess the olive oil adulteration

This study was focused to evaluate the use of FT-IR spectroscopy as an effective analytical tool in order to assess the olive oil (OO) adulteration with cheaper vegetable oil (sunflower oil SFO). Taking a closer inspection to different regions of recorded IR spectra of both pure oil sample (OO, SFO) and their mixture it is noticed that a band shift identified at 3011 cm -1 due to the C-H stretching vibration of the cis-double bond proved to be reliable index for assessing of OO adulteration by SFO addition. Also, the absorbance at 1753 cm, characteristic to the oils with a high saturated fatty acids content and short carbohydrate chain, recorded appreciable chances by increasing of SFO percent added in OO. Based on calibration curve (absorbance versus percent of SFO added in OO), it is possible to determine the degree of OO adulteration. A significant positive correlation (R>0.95) were found in our study. Our data demonstrated that FT-IR spectroscopy prove to be a valuable tool to identify the differences recorded in oil samples spectra and finally, to appreciate the degree of OO adulteration.
The 2003 Heat Wave in France: Dangerous Climate Change Here and Now

In an analysis of the French episode of heat wave in 2003, this article highlights how heat wave dangers result from the intricate association of natural and social factors. Unusually high temperatures, as well as socioeconomic vulnerability, along with social attenuation of hazards, in a general context where the anthropogenic contribution to climate change is becoming more plausible, led to an excess of 14,947 deaths in France, between August 4 and 18, 2003. The greatest increase in mortality was due to causes directly attributable to heat: dehydration, hyperthermia, heat stroke. In addition to age and gender, combinatorial factors included preexisting disease, medication, urban residence, isolation, poverty, and, probably, air pollution. Although diversely impacted or reported, many parts of Europe suffered human and other losses, such as farming and forestry through drought and fires. Summer 2003 was the hottest in Europe since 1500, very likely due in part to anthropogenic climate change. The French experience confirms research establishing that heat waves are a major mortal risk, number one among so‐called natural hazards in postindustrial societies. Yet France had no policy in place, as if dangerous climate were restricted to a distant or uncertain future of climate change, or to preindustrial countries. We analyze the heat wave's profile as a strongly attenuated risk in the French context, as well as the causes and the effects of its sudden shift into amplification. Research and preparedness needs are highlighted.
[Lipid profile frequency and relevancy as an initial test for peripheral vertigo].

OBJECTIVE Determining the prevalence of requesting lipid profile as a first-line diagnostic method in patients having a clinical impression of peripheral vertigo and also determining such request's cost- benefit ratio. METHODS This was a retrospective cross-sectional study of 201 clinical charts regarding patients diagnosed as having peripheral vertigo at the Teletón teaching hospital's outpatient services in Chía between January 2005 and July 2008. Clinical charts drawn up by both general practitioners and medical specialists at first-time visit were compiled and analyzed. RESULTS The patients were aged 6 to 87 years old; 36 % were males and 64 % females. Lipid profile was requested for 76 % of the patients as initial diagnostic method; it was found that 80 % of the results revealed no abnormality. CONCLUSION Although a high prevalence regarding a request for lipid profile first-line study was found for patients having peripheral vertigo, there was no scientific evidence supporting such requirement. Ordering this kind of study not only increases unnecessary costs concerning diagnostic methods but also involves unjustified treatment. Feedback is needed for both doctors and first attention staff to ensure that this type of practice becomes changed.
Impact of management capabilities and environmental dynamism on Nigerian SMEs marketing innovation performance

As Small and Medium Enterprises (SMEs) globally are faced with challenge of globalization, managers have to develop the essential management capabilities that can help stimulate marketing innovation performance of their business enterprises. In line with Resource-Based View (RBV) and Dynamic Capability View (DCV), the study examined the relationship between marketing knowledge management, innovation process, learning capability and Nigerian SMEs marketing innovation performance.Accordingly, the study examined the moderating influence of environmental dynamism on the constructs. Consequently, the study developed a research framework and postulated six research hypotheses on the impact of marketing knowledge management, innovation process and learning capability on marketing innovation performance of Nigerian SMEs, as well as the moderating influence of environmental dynamism. The study adopted cross-sectional survey design in collecting responses from 225 owners/managers of SMEs in Katsina State, Nigeria.The study utilized SPSS in the data analysis, and as expected, H1, H2, H4, H5 and H6 were supported.While, H3 has no statistical support. Therefore, marketing knowledge management and innovation process were significant predictors of SMEs marketing innovation performance. In contrast, learning capability has no significant influence on marketing innovation performance. Interestingly, environmental dynamism exerted significant moderating influence on the relationship between marketing knowledge management, innovation process, learning capability and marketing innovation performance. From the research findings, the study concluded that managers of SMEs need to use resources deployment capabilities as strategic mechanism for improved marketing innovation performance.

RECYCLING INFLOW TURBULENCE GENERATION 2 . 1

Research activities on inflow turbulence generation methods have been vigorous over the past quarter century, accompanying advances in eddyresolving computations of spatially developing turbulent flows with direct numerical simulation, large-eddy simulation (LES), and hybrid Reynoldsaveraged Navier-Stokes–LES. The weak recycling method, rooted in scaling arguments on the canonical incompressible boundary layer, has been applied to supersonic boundary layer, rough surface boundary layer, and microscale urban canopy LES coupled with mesoscale numerical weather forecasting. Synthetic methods, originating from analytical approximation to homogeneous isotropic turbulence, have branched out into several robust methods, including the synthetic random Fourier method, synthetic digital filtering method, synthetic coherent eddy method, and synthetic volume forcing method. This article reviews major progress in inflow turbulence generation methods with an emphasis on fundamental ideas, key milestones, representative applications, and critical issues. Directions for future research in the field are also highlighted.
Registered Blindness and Low Vision in Kuwait

Aim: To estimate the incidence rates and major causes of registered blindness and low vision in Kuwait. Methods: Data on age, gender and cause of blindness and low vision were collected from the Visual Disability Committee while evaluating Kuwaiti citizens applying for a blindness allowance from January 2000 to December 2004. Criteria for legal blindness in Kuwait are visual acuity 6/60 or less in the better eye with best possible correction or a visual field less than 20 degrees around the central fixation point. Incidence rates per 100,000 person years of observation were calculated for both genders in four age subgroups and four severity categories. The causes of registered blindness were classified according to the International Classification of Diseases, 10th edition. Results: 412 persons were registered as blind, 272 males (66.01%) and 140 females (33.98%), mean age 28.7 +/−25.2 years, 39.32% below 20 years of age, 31.79% 21-40 years, 18.68% 41-60 years, and 9.95% 61 years and over . Male gender was prevalent for all age subgroups. The overall incidence rate was 9.97 per 100,000 person years of observation, 13.33 for the male and 6.69 for the female patients. The incidence rates rose from 7.35 for those 20 years and younger to 14.80 for the age subgroup 41-60 and 23.16 for those 61 years and above. The rates of severe visual impairment classified in categories 4 and 5 were higher than the rates for categories 2 and 3. Retinitis pigmentosa was the leading cause of blindness, followed by congenital anomalies and optic atrophy. In the subgroup below 20 the rate of optic atrophy was highest, followed by congenital malformations, retinitis pigmentosa and retinopathy of prematurity. In the next age subgroup (21-40 years), the rate of retinitis pigmentosa was three times as high as in the younger subgroup, followed by optic atrophy, congenital malformations and albinism. In the subgroup 41-60 the incidence rate for phthisis bulbi was twice as high as the rates for retinitis pigmentosa and optic atrophy. For those 61 years and older, the incidence rate of phthisis bulbi was almost five times as high as that for optic atrophy. The incidence rates for the male patients were higher for the major causes of disability in all age subgroups. Conclusions: The overall incidence rate of registered blindness for Kuwait is less than in many other national registries. The marked prevalence of the male gender in all age subgroups is specific for Kuwait. The rates of the leading causes of registered blindness reflect the prevalence of the younger subgroups in our registry. Additional data on co-morbidity and dedicated efforts to reveal unrecognized and unregistered blindness, particularly among females, will overcome the limitations of the registry, and will serve to outline the tendencies in avoidable vision loss and monitor the efficacy of the prevention programs in the future.
Histomorphometric analysis of bone healing at implants with turned or rough surfaces: An experimental study in the dog

Three months after extraction of all mandibular premolars and first molars in six Labrador dogs, two implants, one with a novel turned surface (Combed) and a second with a moderately rough surface (ZirTi), were placed in each side of the mandible in the premolar region of each dog. The 3-D parameters to express roughness and density of peaks were Sa = 1.399 μm and Sds = 0.065 μm2 for the ZirTi surface and Sa = 0.600 μm and Sds = 0.314 μm2 for the Combed surface, respectively.
High incidence of germline BRCA mutation in patients with ER low‐positive/PR low‐positive/HER‐2 neu negative tumors

The 2015 National Comprehensive Cancer Network guidelines recommend that genetic counseling and germline BRCA mutation testing be offered to women under age 60 with triple‐negative breast cancer (TNBC). As a result of the 2010 American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines for breast cancer, patients with breast cancers that are estrogen receptor (ER) or progesterone receptor (PR) low‐positive (1%‐9% on immunohistochemistry) are no longer strictly considered to have TNBC and may not be referred for genetic counseling. However, the incidence of BRCA mutation in patients with hormone receptor (HR) low‐positive breast cancers remains unknown, and current ASCO/CAP guidelines may result in undertesting for BRCA mutations.
Diagnostic and prognostic value of [(18)F]fluorodeoxyglucose positron emission tomography for recurrent head and neck squamous cell carcinoma.

PURPOSE Patients with recurrent head and neck squamous cell carcinoma (HNSCC) present a diagnostic and therapeutic challenge. We evaluated the diagnostic accuracy and prognostic value of [(18)F]fluorodeoxyglucose positron emission tomography (PET) in this patient population. PATIENTS AND METHODS We performed a retrospective review of 143 patients with previously treated HNSCC who underwent 181 PET scans at our institution from May 1996 through April 2001 to detect recurrent disease. Disease recurrence within 6 months was used as the gold standard for assessing true disease status at PET. RESULTS With equivocal sites considered positive, the sensitivity and specificity of PET for detecting recurrence overall were 96% and 72%, respectively. PET was highly sensitive and specific at regional and distant sites. At local sites, sensitivity was high, but specificity was lower because of false-positive findings. One fifth of all false-positive PET scans occurred at sites of known inflammation or infection. The area under the curve for a receiver operator characteristic curve on the basis of standardized uptake value (SUV) was 0.882 +/- 0.025. PET interpretation, SUV, and physical examination were independent predictors of relapse-free and overall survival in a time-dependent, multivariate proportional hazards model. An increase in SUV by one unit increased the relative risk (RR) of relapse by 11% and the RR of death by 14%. A positive PET interpretation increased the RR of relapse by four-fold and the RR of death by seven-fold. CONCLUSION PET was a highly sensitive method of detecting recurrent HNSCC and provided important prognostic information for relapse-free and overall survival.

Heart pump system in heart-coronary artery-myocardial bridge circulation apparatus

The cardiac muscles that cover the surface of the coronary artery are called Myocardial Bridge. But so far many research methods on the myocardial bridge are involved with clinical patients or animals, so they have some limitations (e.g. systematicless, difficulties in measuring the flow of the coronary artery and so on). Designing a heart-coronary artery-myocardial bridge circulation system model provides a good approach to solve above problems. But documents on this subject seldom have been reported until now. The heart pump is the key part of the whole simulation system. It can simulate the waveform of the pressure and adjust the flow and the frequency in our experiments. Successfully developing the heart pump produces an alternative experimental method to go further into other problems of the circulation system.
Actions of acetylcholine in the guinea‐pig and cat medial and lateral geniculate nuclei, in vitro.

1. The mechanisms of action of acetylcholine (ACh) in the medial (m.g.n.) and dorsal lateral geniculate (l.g.n.d.) nuclei were investigated using intracellular recordings techniques in guinea‐pig and cat in vitro thalamic slices. 2. Application of ACh to neurones in guinea‐pig geniculate nuclei resulted in a hyperpolarization in all neurones followed by a slow depolarization in 52% of l.g. n.d. and 46% of m.g. n. neurones. Neither the hyperpolarization nor the slow depolarization were eliminated by blockade of synaptic transmission and both were activated by acetyl‐beta‐methylcholine and DL‐muscarine and blocked by scopolamine, indicating that these responses are mediated by direct activation of muscarinic receptors on the cells studied. 3. The ACh‐induced hyperpolarization was associated with an increase in apparent input conductance (Gi) of 4‐13 nS. The reversal potential of the ACh‐induced hyperpolarization varied in a Nernstian manner with changes in extracellular [K+] and was greatly reduced by bath application of the K+ antagonist Ba2+ or intracellular injection of Cs+. These findings show that the muscarinic hyperpolarization is mediated by an increase in K+ conductance. 4. The ACh‐induced slow depolarization was associated with a decrease in Gi of 2‐15 nS, had an extrapolated reversal potential near EK, and was sensitive to [K+]o, indicating that this response is due to a decrease in K+ conductance. 5. In contrast to effects on guinea‐pig geniculate neurones, applications of ACh to cat l.g. n.d. and m.g. n. cells resulted in a rapid depolarization in nearly all cells, followed in some neurones by a hyperpolarization and/or a slow depolarization. The rapid excitatory response was associated with an increase in membrane conductance, had an estimated reversal potential of ‐49 to ‐4 mV and may be mediated by nicotinic receptors. The hyperpolarization and slow depolarization were similar to those of the guinea‐pig in that they were associated with an increase and decrease, respectively, of Gi, and were mediated by muscarinic receptors. 6. The muscarinic hyperpolarization interacted with the intrinsic properties of the thalamic neurones to inhibit single‐spike activity while promoting the occurrence of burst discharges. The muscarinic slow depolarization had the opposite effect; it brought the membrane potential into the range where burst firing was blocked and single‐spike firing predominated. Depending upon the membrane potential, the rapid excitatory response of cat geniculate neurones could activate either a burst or a train of action potentials. (ABSTRACT TRUNCATED AT 400 WORDS)
Cross-Country Differences in Intergenerational Transmission of Poverty in Europe: Macro-Economic and Institutional Determinants

The intergenerational transmission of poverty (ITP) is a very relevant problem, since income in the extremes of the distribution tends to be particularly persistent across generations. This paper contributes to the literature on the determinants of differences in the intensity of ITP across countries by explicitly testing how macro/aggregate features shape it. To that aim a multilevel logit model is estimated on a sample of around 30 European countries taken from the EU-SILC 2011 module on Intergenerational transmission of disadvantages, enriched with a set of macro/aggregate indicators. Our results show that (a) the heterogeneity of ITP processes across countries is quite relevant; (b) ITP is more intensive in countries where there is a higher intra-generational income inequality or weak investments in the reduction of inequality; (c) public expenditure aimed at providing equality of opportunities in access to higher education is related with less intensive ITP; (d) public policies aiming at reducing the impact of job losses on households’ income are also correlated with a reduction in the intensity of ITP.
Mechanical Properties, Failure Mode, and Microstructure of Soil-Cement Modified with Fly Ash and Polypropylene Fiber

In order to investigate the effects of fly ash and polypropylene fiber on mechanical properties, failure mode, and microstructure of soil-cement, the unconfined compression test, splitting tension test, and scanning electron microscopy (SEM) test of soil-cement with different polypropylene fiber contents (0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% by weight of dry soil) and fly ash contents (0%, 4%, 8%, and 12% by weight of dry soil) were carried out. The compressive and tensile strengths, deformation characteristics, failure mode, and microstructure of soil-cement modified with fly ash and polypropylene fiber were analyzed. The results show that the unconfined compressive strength and splitting tensile strength of soil-cement show a trend of increasing first and then decreasing with the increase of polypropylene fiber and fly ash content. Under the condition of 0.4% polypropylene fiber and 8% fly ash, the unconfined compressive strength and the splitting tensile strength are 4.90 MPa and 0.91 MPa, respectively, which increased by 32.79% and 51.67% as compared with the plain soil-cement, respectively. When 8% fly ash was used in the experiment, the unconfined compressive peak strain and the splitting tensile peak strain of the inclusion of 0.4% polypropylene fiber were 0.0410 and 0.0196, respectively. The corresponding peak strains were increased by 20.94% and 68.97% as compared with non-fiber-stabilized soil-cement, respectively. The stress-strain curve of fly ash soil-cement modified with polypropylene fiber can be divided into compaction phase, linear rise phase, nonlinear rise phase, and failure phase. Polypropylene fiber constrains the lateral deformation of fly ash soil-cement, which improves the peak strain and the failure mode of soil-cement.
The dry sliding wear behaviour of aluminum composites: a review

Fluctuating petroleum prices, environmental concerns and the understanding that petroleum is a finite resource have encouraged investigation into alternative fuels. Coconut oil can be potentially be used as the triglyceride feedstock for biodiesel production. The objective of this study was to complete energy performance analyses of four (4) coconut oil biodiesels. The energy performance metrics investigated were net energy ratio (NER), net energy balance (NEB), net renewable energy value (NREV) and fossil energy ratio (FER). NER values ranged from 0.51 to 0.77, NEB from -12.00 MJ/L to -46.21 MJ/L, NREV from 9.00 to 21.31 MJ/L and FER from 1.52 to 2.88. The energy metrics implied that the small-scale transesterification process is neither energy-efficient nor sustainable in Trinidad and Tobago. At the atom efficient 3:1 methanol to oil ratio, the NREV and FER values are improved, however, compared to the 6:1 methanol to oil ratio process. Additionally, since most of their physical properties are already within specification for use in the local vehicular market, all biodiesels are a prospective component of environmentally friendly blends with petrodiesel.
