Analytic solutions and transmission eigenvalues in isotropic poroelasticity for bounded domain, scattering of obstacles and fluid-solid interaction problems in 2D

In this report, we construct analytical solutions and study numerically the well-posedness of several problems concerning the isotropic poroelastic equation in axisymmetry. Theproblems in consideration are cylindrical bounded domains, the scattering of plane wave in poroe-lastic by penetrable/impenetrable circular obstacles and lastly fluid-solid interaction problem withcircular solid obstacles for closed, open and intermediate pore boundary type. Since we have an-alytic expressions for the coefficients / transmission matrices, well-posedness is investigated byprobing for zeros of the determinant of these matrices. Our investigation includes the effect ofmaterial parameters and different degrees of viscosity. The first novelty of the work is the proposalof a definition of outgoing solutions for isotropic poroelasticity. The second novelty is the obser-vation that there are modes in fluid-poroelastic interaction problems without viscosity which arethe equivalent of Jones’ modes for fluid-elastic problem, and that these modes cease to exist in thepresence of viscosity. We found out that the presence of viscosity removes the eigenvalues, whichexist without viscosity and whose existence is expected for bounded domains.
Factors associated with the uptake of intermittent preventive treatment of malaria in pregnancy in the Bamenda health districts, Cameroon

Introduction The World Health Organization (WHO) recommends that in malaria endemic areas with moderate to high transmission rates, pregnant women presenting for antenatal clinic (ANC) should receive at least three doses of intermittent preventive treatment in pregnancy (IPTp) for malaria between the 16th and 36th weeks of pregnancy at intervals of 4 weeks between doses. Several challenges remain in effective implementation of IPTp policy making the targeted coverage (80%) of the third doses of IPTp far from being achieved. The main objective of this study was to assess factors associated with the uptake of IPTp among pregnant women attending ANCs in the Bamenda Health District. Methods To reach our objectives, we carried out a cross-sectional study following informed consent with thirty-nine (39) healthcare workers (HCW) and four hundred (400) pregnant women who were either in the third trimester of pregnancy or had recently given birth in any of thirty-six (36) health facilities (HF) within the Bamenda Health District (BHD) from May to August 2014. All sites within the BHD were included. The participants were selected by simple random sampling. The principal research instrument was a structured and pre-tested questionnaire that was designed to capture socio-demographic data and data related to stage of pregnancy and knowledge about IPTp. Data was entered using Ms Excel and analysed using SPSS v20.0. Descriptive statistics (frequencies and percentages) was used to report findings. We used Chi-Square test to compare the categorical variables (Fischer’s exact test was used in cases were conditions for Chi-Square test were not met). Results Uptake for at least one dose of IPTp was 95.3% (381/400) and 54.9% (209/400) had received all three doses, 15.5% (59/400) received only one dose and 4.8% (19/400) did not receive any of the doses of IPTp. Knowledge about IPTp was associated with an increase uptake of IPTp (P<0.001). All health care providers were knowledgeable about the importance and use of IPTp. However, 35.9% reported not receiving any training on IPTp. Among the health providers, 28.2% did not know when to start IPTp and 43.59% did not know when to stop IPTp. Out of all the health care providers, 30.77% complained of medication (sulfadoxine-Pyrimethamine) stock out and 84.62% practiced the policy of direct observed therapy. Conclusion The uptake of the third dose of IPTp is poor in the Bamenda Health District and this may be attributed to medication stock out and inadequacy of routine trainings for the health providers. The good practice observed was that of direct observed therapy by HCWs. Patient knowledge about IPTp in our study was associated with better uptake of IPTp. Encouraging education of pregnant women on the importance of IPTp, providing routine training to HCWs and promoting direct observation of therapy may improve on IPTp uptake during pregnancy.
Assessment of an educational program in diabetes for the primary care level

Aim: To develop and evaluate a multi-professional educational program on diabetes mellitus, based on local conditions for the primary level of health attention (EBAIS), Methodology: An active–participative course of 35 hours (70% practice, 30% theory) was developed in three Costa Rican geographical areas. Topics were taken from the felt needs of the health providers and patients (previous study), also from the duties specified for the primary level. Evaluation was based on the increase of both theory (knowledge) and practice (skills).
Effect of acetic acid hydrolysis on the characteristics of water soluble chitosan

Chitosan is a derivative product of chitin deacetylation and has many functions in food industry. However, it has limitation on application caused by low solubility in water. In order to increase the solubility in water, the hydrolysis using acetic acid was performed to reduce the molecular weight. The concentration of acetic acid, temperature of hydrolysis and hydrolysis time related to the solubility were investigated. Hydrolysis using 5% acetic acid was able to produce water soluble chitosan (WSC) with a molecular weight of 198.64 kDa and 46.10% solubility in water. WSC that was obtained at 60 oC for 90 min of hydrolysis process in 5% acetic acid had characteristics of viscosity, molecular weight, solubility in water and deacetylation degree were 0.85 cP, 166.34 kDa, 53.66% and 92.92%, respectively.
Sex on TV 4 2005: a Kaiser Family Foundation report.

One of the critical challenges facing young people today is developing a healthy understanding of their sexuality. The U.S. Surgeon General has underscored the importance of this task as one of the nations leading public health concerns. Such knowledge developed in the formative years builds the foundation for beliefs and attitudes about sex that can influence each individuals life-long pattern of sexual behavior. Parents peers and schools play a central role in the process of sexual socialization today just as they have long in the past. Yet in contemporary society young people also encounter another important element likely to contribute to their sexual socialization: the mass media and in particular television. Indeed some have labeled the media a "sexual super peer" because of its role in establishing norms and expectations for young people in this area. Televisions treatment of sexual content in recent years has grown increasingly frequent and prominent raising important societal concerns in an era when decisions about sexual behavior inevitably involve public health issues. Each year in the U.S. one of every four sexually active teens is diagnosed with a sexually transmitted disease (Institute of Medicine 1997). From a broader perspective approximately 19 million STD infections are diagnosed annually with nearly half of them afflicting teens and young adults between 15-24 years of age. In addition the rate of unplanned teen pregnancy in the U.S. remains among the highest of all industrialized countries despite recent declines driven by the fact that one-third (34%) of young women become pregnant at least once before reaching their 20th birthday.

New FDSOI-based integrated circuit architectures sensitive to light for imaging applications

A new type of light sensor called FDPix, composed of one transistor (1T) per pixel is investigated. It consists in co-integrating an FDSOI (Fully-Depleted Silicon-On-Insulator) transistor with a photodiode to enable light sensing through optical back biasing. The absorption of photons and resulting photogenerated charges in the diode will result in a Light Induced VT Shift (LIVS). The LIVS is due to a capacitive coupling between the front and back gate of the FDSOI transistor and represents the key performance metric to be extracted and optimized. In this work, the device behavior in dc and transient domains was thoroughly investigated and modeled. Although not limited to this node, all the devices tested were fabricated using 28nm node FDSOI technology. By means of TCAD simulations and opto-electrical characterization, the device parameters such as Body Factor (BF) and junction profile were optimized to improve its performance. It was found that the FDPix is in fact a dual response sensor. It exhibits a linear response at low light intensity which results in high sensitivity, and a logarithmic response at higher intensities that ensures a high dynamic range (DR) of more than 120dB. The dedicated developed model is implemented in SPICE environment for circuit design. New pixel circuit in analog and digital domain, based on the FDPix were designed, fabricated, and tested. The results obtained and presented in this work, shows the potential of using the FDPix sensor for smart, highly embedded, low power image sensors for More-than-Moore applications.
THE EVOLUTION OF SOME HEMATOLOGICAL AND IMMUNOLOGICAL MARKERS AT PATIENTS WITH B HEPATITIS VIRUS

The study aimed at the mathematics processing of some hematological and immunological indices in subjects infected with heptatitic virus of B type, that were investigated in S.C. Dorna Medical S.R. L. Vatra Dornei Lab, between December 2011 – February 2012. From the statistical study of the hematological and immunologic profile at patients with B hepatitis shows that the highest percent of immunological clinical investigations are recorded, generally, in the age categories of 40-59 years and 25-39 years, while the hematological tests predominates at the groups 40-59 years and 60- 79 years.
DETECTION OF DISEASE: POSSffiiLITIES AND LIMITATIONS

Much has and can be done to make blood transfusion as safe as possible. These include preventive measures beginning with donor education, screening, selection and deferral procedures, post-donation product quarantine and donor tracing when transmission of an infectious agent occurred. In addition we can test the blood for the presence of infectious agents. We can also use inactivation methods like solvent and detergent, or replace the use of blood by alternatives such as recombinant products, for instance clotting factor VIII or IX or the use of blood substitutes. In this paper we will further focus on the screening of blood for infectious agents. At the end it will be clear that blood safety is not equal to the detection of an infectious agent. In order to come as close as possible to the detection of disease the decision to screen for infectious agents should be based on certain principles which will be discussed later.
A Single-Cell Transcriptional Roadmap of the Mouse and Human Lymph Node Lymphatic Vasculature

Single-cell transcriptomics promises to revolutionize our understanding of the vasculature. Emerging computational methods applied to high dimensional single cell data allow integration of results between samples and species, and illuminate the diversity and underlying developmental and architectural organization of cell populations. Here, we illustrate these methods in analysis of mouse lymph node (LN) lymphatic endothelial cells (LEC) at single cell resolution. Clustering identifies five well-delineated subsets, including two medullary sinus subsets not recognized previously as distinct. Nearest neighbor alignments in trajectory space position the major subsets in a sequence that recapitulates known and suggests novel features of LN lymphatic organization, providing a transcriptional map of the lymphatic endothelial niches and of the transitions between them. Differences in gene expression reveal specialized programs for (1) subcapsular ceiling endothelial interactions with the capsule connective tissue and cells, (2) subcapsular floor regulation of lymph borne cell entry into the LN parenchyma and antigen presentation, and (3) medullary subset specialization for pathogen interactions and LN remodeling. LEC of the subcapsular sinus floor and medulla, which represent major sites of cell entry and exit from the LN parenchyma respectively, respond robustly to oxazolone inflammation challenge with enriched signaling pathways that converge on both innate and adaptive immune responses. Integration of mouse and human single-cell profiles reveals a conserved cross-species pattern of lymphatic vascular niches and gene expression, as well as specialized human subsets and genes unique to each species. The examples provided demonstrate the power of single-cell analysis in elucidating endothelial cell heterogeneity, vascular organization and endothelial cell responses. We discuss the findings from the perspective of LEC functions in relation to niche formations in the unique stromal and highly immunological environment of the LN. Highlights Computational alignments (“trajectories”) predict LN LEC organization in situ, revealing a continuum of phenotypes punctuated by specialized clusters Multiple intermediate phenotypes suggest LEC malleability Gene profiles define niche-specific functional specialization Medullary sinus LECs are comprised of Ptx3-LECs and Marco-LECs Distinct mechanisms for pathogen interactions and matrix modeling Ptx3-LECs: paracortical and central medullary sinuses near hilus; enriched for genes driving lymphangiogenic responses and lymphocyte egress Marco-LECs: peri-follicular medullary sinuses; macrophage-associated genes, complement and coagulation cascade Niche-specific responses to inflammation IFN gene responses in SCS floor and medullary sinus LECs Suppression of LEC identity genes in responding subsets Conserved and unique LEC subsets and gene programs across species Core subsets common to mouse and human Greater diversity of subsets and intermediates in human LN LECs

Assessment of Inflammatory Markers in Keelvayu Nivarana Churunam (KNC) Supplementation to Carrageenan-Induced Inflammatory Rats

The carrageenan-induced paw edema is a well-defined model of acute inflammation that a variety of inflammatory mediators involves in its development and has wildly been used to evaluate the anti-inflammatory effect of natural products. The results of the current study suggested that KNC possessed anti-inflammatory effects in carrageenan-induced rats. The antiinflammatory mechanism of KNC may be related to the reduction of oxidative stress markers as MDA, GPx, Catalase and inflammatory markers PGE2, NO2, TNFα, IL6, IL-10, Myloperoxidase and IgM. Furthermore, the protective effect of KNC may result from anti-oxidative effects. Our findings provide new perspectives on the therapeutic use KNC in the management of inflammatory diseases including arthritis.
Effectiveness of Frequency of Testing on Students’ Study Habits in Mathematics among Senior Secondary Schools in Ogun State, Nigeria

Mathematics plays a vital role in the scientific and technological advancement of everynation, and Nigeria is no exception. Besides its importance as a school subject, it isassociated with more academic and career opportunities. However, students’ poorachievement in mathematics may have led to questioning students’ study habits. Constantpractice and repeated reading is expected to enhance students’ understanding andknowledge of mathematics. Thus, this study seeks to examine the effectiveness offrequency of testing on students’ study habits in mathematics among secondary schools inOgun State, Nigeria. The study employed a quasi-experimental pretest-posttest controlgroup design. The population of the study comprised all senior secondary school studentsin Ogun State, Nigeria. A sample size of 157 students was selected through the multistage sampling process. The research instrument titled Study Habits Inventory was usedto collect relevant data for the study. Two hypotheses were tested using descriptivestatistics and Analysis of Covariance (ANCOVA). The hypotheses were tested at 0.05level of significance. The study revealed that students tested most frequently developedimpactful study habits towards the learning and practices of mathematics. In addition, thestudy revealed that gender was not a significant factor when trying to improve students’study habits via testing frequency. It was recommended, based on the findings from thisstudy, that frequency of testing of every week should be adopted in the teaching, learningand mastery of mathematics concepts and exercises.

Conclusions: Cognitive behavioral group therapy sessions substantially contributed to the improvement of hope and adjustment in patients with hepatitis B.
Improved Doppler Positioning Techniques for Stand-Off Scenarios

In “stand-off” scenarios, an estimate of the bearing to an emitter can be easily calculated from measurements of the received frequency, position, and velocity of receivers. This technique is only effective if the measured frequencies can be reliably associated with a single emitter that is far away. We show how to determine if the receivers’ measurements correspond to a single emitter in a stand-off scenario, eliminate outliers, and estimate the unknown transmit frequency.

Metal-Support Synergy of Supported Gold Nanoclusters in Selective Oxidation of Alcohols

Gold catalysts have been reported to exhibit good performance in aerobic oxidation of alcohols, but the intrinsic origin of the catalytic reactivity is still illusive. The catalyst preparation method, the morphology of the gold particles, and even the support might be key factors that determine the activity. Here, we prepared a series of gold catalysts with different supports, i.e., the hydrotalcite (HT), ZnO, MgO, Al2O3, and SiO2, by using the atomically controlled Au25 nanoclusters (NCs) as the gold precursor. The characterization results of the X-ray diffraction (XRD), UV-vis and transmission electron microscopy (TEM) show that the gold particles were mostly uniformly distributed on the supports, with a mean particle size within 3 nm. In aerobic oxidation of benzyl alcohol, the MgAl-HT- and Al2O3-supported Au25 NCs display good performances, with turnover frequency (TOF) values of ~2927 and 2892 h−1, respectively, whereas the SiO2-, MgO-, and ZnO-supported analogues show much inferior activity. The high resolution TEM and X-ray photoelectron spectra (XPS) results suggest that the interactions between gold and the supports in different samples are differing, which influences the morphology and the nature of gold. Our results further point to the importance of acid-base property of the support and the metal-support synergy rather than the gold particle size alone in achieving high-performance in selective alcohol oxidation. Moreover, this work provided a good way to design gold catalysts with controllable sizes that is crucial for understanding the reaction process in aerobic oxidation of alcohol.
