The Archaeocyaths of Ifrane (Western Anti-Atlas-Morocco): Geological Value and Geotourism Development

In the western part of the Anti Atlas, the Cambrian formations known since long (Nice, 1924; Bourcard, 1927; Bung & Netlner, 1933), have been the subject of a very detailed stratigraphic approach. The sedimentological work affecting the lower Cambrian of the Western Anti Atlas is rare. It concerns mainly: a lithostratigraphic description and a summary interpretation of the environmental sedimentary formations. Indeed, recent sedimentological data allowed a new lithostratigraphic division of the Lower Cambrian succession in three lithostratigraphic series. These, are characterized, each one, by a particular microbialitic builds ups, resulted, probably, from Lower Cambrian marine ecosystem variations. The first step, the stromatolitic series, represents a long period in which a large area of the Anti-Atlasic platform was occupied by peritidal cyanobacterial mats. The second step, represented by the Thrombolites series, marks a global sea level rise (Thrombolites proliferation) relayed by a massive silico-clastic supply inputs. And the third stage of evolution during which the medium sufficiently deepened to allow the installation of the distal facies platform. The development of the Archaeocyaths seems to be one of the precursors of dendritic form acquired by certain microbial communities. Dating Neoproterozoic, the Archaeocyaths of Ifrane, whose morphological diversity and the microbial communities associated with them, are a focus for the industry of ornamental rocks in Ifrane in the Moroccan western Anti-Atlas. In this area, the structural diversity of the Archaeocyaths is very pronounced, which facilitates the systematic division and their use in stratigraphy. The perforations or pores vary in number, size and arrangement, those whose walls are stretched in the subdivision pore channels or tubes which may be linear, bent, or inclined in the case of thicker walls. Indeed, the main objective of this work is to highlight the “Archaeocyathans mounds” as a geological heritage through the study of varied silico-clastic and carbonate predominate components facies. Regrettably, the surexploitation of the Archaeocyaths in the ornamental industry and mining activities may lead to their death in the absence of regulatory laws of their exploitation. Clues are offered to make the Archaeocyaths a geological site, a geological destination, thing that necessitate the conduct of a number of approaches, the mobilization of various networks of actors but also the establishment or adaptation of infrastructure, home or mediation.
Differential Regulation of the Two grp170 Paralogues of Caenorhabditis elegans

of a Thesis Differential Regulation of the Two grp170 Paralogues of Caenorhabditis elegans Caenorhabditis elegans has two loci encoding the large eukaryotic molecular chaperone Grp170, grp170a (T24H7.2) and grp170b (T14G8.3). To investigate expression of the two C. elegans grp170 loci during ER stress, the Unfolded Protein Response (UPR) was induced with the glycosylation inhibitor tunicamycin. Levels of grp170a mRNA did not significantly change in response to tunicamycin treatment while the levels of grp170b mRNA increased 6-fold. ER stress induction of grp170b was unaffected in worms defective for the ATF6 and PERK-1 UPR signal transduction pathways. However, worms defective for the IRE-1 dependent UPR pathway failed to induce grp170b. The expression of grp170 mRNA was analyzed in nematodes homozygous for the grp170a deletion allele tm3109 or for the grp170b deletion allele ok502. Expression of grp170a mRNA was unaffected by the loss of grp170b. In contrast, grp170b was induced 83 fold in nematodes deficient for grp170a. To further investigate whether loss of either grp170 loci induces UPR, the expression of another UPR responsive gene, hsp-4, was analyzed. In nematodes lacking grp170b, expression of hsp-4 mRNA was not affected. However, in nematodes lacking grp170a, the UPR responsive hsp-4 mRNA was up-regulated 38 fold. These data suggest that while grp170a plays a critical role in ER protein folding, it is not itself inducible by the UPR. On the other hand grp170b seems to play a less critical role in protein folding under non-stress conditions, it is the grp170 locus that is induced by the UPR.
Screening of Coarse Varieties for Direct Seeded Rice

A farmer test was directed to decide the suitable variety under DIRECT SEEDED RICE (DSR) without compromising the yield and quality of rice. Three varieties kala Shah Kaku (KSK-133, KS-282, and KSK-434) were tested. The most suitable coarse variety under Direct Seeded Rice was kala shah kaku (KSK-133) at local condition performed well in yield and quality as well. Coarse variety KSK-133 was better in improving the tillers, panicle length, 1000 grains weight, number of grains per panicle, and yield. It also reduces the sterility percentage along with quality parameters. Overall, in conclusion, for improvement of rice yield and quality Kala Shah Kaku (KSK-133) variety may be recommended as best one in Direct Seeded Rice (DSR) under local conditions.
Biocompatible Film Made from Silkworm Cocoon

A biocompatible film is needed to cover an open or wide wounds. In this research, biocompatible film is created from cocoon of silkworm Bombyx mori. The sericin and fibroin proteins of the cocoon were separated. Only fibroin protein of the cocoon was used for this purpose. The fibroin was ground mechanically in water. The resulting fibroin solution was dropped onto a glass surface and heated at 60C until solidify to become a film. The microstructure of the membrane was investigated by using optical microscope. The human osteosarcoma cell line (U2OS) was cultivated for 24 hours. It was found that the cells are able to attach and grow on the fibroin film of Bombyx mori during following 24 hours as documented by microscopic observation. This is an indication that the fibers may be used as degradable biomaterial.
DSM EXTRACTION AND EVALUATION FROM GEOEYE-1 STEREO IMAGERY

The newest very high resolution (VHR) commercial satellites, such as GeoEye-1 or WorldView-2, open new possibilities for cartographic applications, orthoimages generation and extraction of Digital Surface Models (DSMs). These DSMs are generated by image matching strategies from VHR satellite stereopairs imagery, reconstructing the 3D surface corresponding to the first surface view of the earth containing both microrelief (buildings, trees and so on) and bare terrain. The main aim of this work is to carry out an accuracy assessment test on the DSMs extracted from a GeoEye-1 stereopair captured in August 2011. A LiDAR derived DSM taken at the same month that the satellite imagery was used as ground truth. The influence of factors such as number of Ground Control Points (GCPs), sensor models tested and the geoid employed to transform the ellipsoid to orthometric heights were going to be evaluated. In this way, different sets of GCPs ranging from 7 to 45, two sensor models and two geoids (EGM96 and EGM08, the last adapted for Spain vertical network by the Spanish's National Geographic Institute) were tested in this work. The photogrammetric software package used was OrthoEngine from PCI Geomatica v. 10.3. 2. OrthoEngine implements both sensor models tested: (i) the physical model developed by Toutin (CCRS) and, (ii) the rational function model using rational polynomial coefficients supplied by the vendor and later refined by means of the zero order linear functions (RPC0). When high accurate and well-distributed GCPs were used, the planimetric and vertical accuracies of DSMs generated from the GeoEye-1 Geo stereopair were always better than 0.5 m. Using only 7 GCPs and RPC0, a vertical accuracy around 0.43 m measured as standard deviation was attained. The geoid used by OrthoEngine (EGM96) produced similar results that the EGM08 adapted for Spain vertical network.
Nutritional characteristics of BMR mutant and normal sorghum genotypes used for cutting and grazing

This study evaluated the nutritional characteristics of BMR mutant and normal sorghum genotypes, eleven BMR mutants and nine normal. Seeds were sown in a randomized block design with three blocks, in which each genotype was a treatment. The nutritional characteristics were analyzed at 42 days of regrowth after the first cut, determined for DM, EE, ash, CP, NDIN, NIDA, NDF, ADF, NFC, CT, HCEL, CEL and NGLs. Regarding DM, EE, ash, NDIN, NIDA, NDF, FDA and HCEL, there were no differences between genotypes. As for CP, there were differences, with mean levels ranging from 9.77% for BR001AXTX2785bmr to 16.45% for BR001AxTX2784. Considering CT and NFC, there were differences in the mean levels that ranged from 75.21 to 83.28% for BR007AxTX2785bmr and BR001AXTX2785bmr, and from 17.46 to 25.51% for CMSXS156AxTX2785bmr and IS10428xTX2784, respectively. In relation to CEL and LGN significant difference were detected, the mean levels varied between 22.30 and 27.94% for the IS10428xTX2784 and TX635AxTX2785bmr, and from 3.08 to 7.31% for BR007AxTX2785bmr and BR001AxTX2784, respectively. The genotypes IS10428xTX2784 and BR007AxTX2784 are the most suitable for use in ruminant feed.
Examining Career Readiness and Positive Affect in a Group of College Students with Disabilities: A Pilot Study.

Data were collected from 47 college students with disabilities at a large Midwestern university using the Career Thoughts Inventory ([CTI]; Sampson, Peterson, Lenz, Reardon, Saunders, 1996) and the Positive and Negative Affect Scale ([PANAS]; Watson, Clark, & Tellegen, 1988). Initial results revealed no significant differences for CTI total, Decision-Making Confusion (DMC), and Commitment Anxiety (CA) subscales when compared to the normative samples of the CTI. However, significant differences were found for the External Conflict (EC) subscale. Results further indicated that individuals who were identified as having the highest level of dysfunctional career thoughts were also found to have significantly higher levels of negative affect and lower levels of positive affect. Overall, the results of this pilot study provide support for the need to address career thoughts in college students with disabilities and the impact of affect on their career decision-making process.
Miniaturized Forced-Mode Ring Resonator with Capacitive Loading

The miniaturization of conventional ring resonators is demonstrated by forcing a voltage minimum at one end of the resonator. In addition, the resonator is loaded with a capacitance to achieve further miniaturization and reducing its sensitivity to substrate thickness tolerance. The flnal resonator is 73% smaller than a conventional ring resonator and has a tenfold decrease in sensitivity to substrate thickness variations. Using this resonator a 4-pole quasi- elliptic fllter is fabricated showing good agreement between simulation and experimental results.
In Tandem or Out of Sync? Academic Economics Research and Public Policy Measures

This paper investigates whether academic research attention to certain public policy related measures (including unemployment, inflation, bankruptcies, and GDP) is correlated with empirical measurements of the measures themselves. In other words, when unemployment rises, does academic research attention to the matter increase? Or do economists pursue research interests relatively uninfluenced by policy shocks on the ground, at least in the short run? Text-analysis based results imply that economic attention to key public policy terms does correlate with empirical movements of the terms in most instances, however, the stronger and more consistent correlation is between use of public policy terms in the academic literature and discussion of them by the broader public.

Impact of wall hydrophobicity on condensation flow and heat transfer in silicon microchannels

While microchannel condensation has been the subject of several recent studies, the critical impact of wall hydrophobicity on the microchannel condensation flow has received very little attention. The paper experimentally studies steam condensation in a silicon microchannel 286 µm in hydraulic diameter with three different wall hydrophobicities. It is found that the channel surface wettability has a significant impact on the flow pattern, pressure drop and heat transfer characteristic. Spatial flow pattern transition is observed in both hydrophobic and hydrophilic channels. In the hydrophobic channel, the transition from dropwise/slugwise flow to plug flow is induced by the slug instability. In the hydrophilic channel, the flow transition is characterized by the periodic bubble detachment, a process in which pressure evolution is found important. Local temperature measurement is conducted and heat flux distribution in the microchannel is reconstructed. For the same inlet vapor flux and temperature, the hydrophobic microchannel yields higher heat transfer rate and pressure drop compared to the hydrophilic channel. The difference is attributed to the distinction in flow pattern and heat transfer mechanism dictated by the channel hydrophobicity. This study highlights the importance of the channel hydrophobicity control for the optimization of the microchannel condenser.
Scalar Curvature and Stability of Toric Varieties

We define a stability condition for a polarised algebraic variety and state a conjecture relating this to the existence of a Kahler metric of constant scalar curvature. The main result of the paper goes some way towards verifying this conjecture in the case of toric surfaces. We prove that, under the stability hypothesis, the Mabuchi functional is bounded below on invariant metrics, and that minimising sequences have a certain convergence property. In the reverse direction, we give new examples of polarised surfaces which do not admit metrics of constant scalar curvature. The proofs use a general framework, developed by Guillemin and Abreu, in which invariant Kahler metrics correspond to convex functions on the moment polytope of a toric variety. This paper is a step towards the solution of the general problem of finding conditions under which a complex projective variety admits a Kahler metric of constant scalar curvature. The pattern of the answer one expects is that this differential geometric condition should be equivalent to some notion of “stability” in the sense of Geometric Invariant Theory. This expectation is probably now an item of folklore: going back to suggestions put forward by Yau in the case of KahlerEinstein metrics, and the many results of Tian and others in this case; reinforced by a detailed formal picture which makes clear the analogy with the well-established relation between the stability of vector bundles and Yang-Mills connections [5]. Here, we begin the investigation of
Cosmogenic isotopes Be-7, Be-10, C-14, Na-22 and Cl-36 in the atmosphere: Altitudinal profiles of yield functions

Production of isotopes by cosmic rays in the Earth’s atmosphere plays a key role in many studies in solar physics, geophysics, archeology and other fields. For those purposes, precise quantitative modeling of their production is crucial, and high-resolution altitudinal profiles of production rates are in high demand. Here we present detailed and consistent yield functions of isotopes Be-7, Be-10, C-14, Na-22 and Cl-36 produced by energetic particles in the atmosphere. Comparison of reconstructions of the Be-10 deposition flux in 1951-2013 and around 775 AD with ice core measurements is shown for illustration of application of our yield functions.
Income Inequality Among Seniors in Canada: The Role of Women's Labour Market Experience

The distribution of income among seniors in Canada has changed substantially over the past decade, reflecting an overall increase in income and an increase in income inequality. In this study I decompose the distribution of income among senior couples to determine the extent to which changes in the labour market activity and retirement experiences of women and men have contributed to this shift in the income distribution. I use data from the Canadian Survey of Labour and Income Dynamics, 1996 and 2006, and the methods of Firpo, Fortin and Lemieux (2007, 2009). Results suggest increases in women's access to pension income and employment have driven increases in income across the distribution with relatively small disequalizing eff ects. Increases in women's access to public pensions have had important equalizing e ffects, while most of the increase in senior income inequality can be attributed to increases in senior men's and women's education levels.
Volatility as an Asset Class: European Evidence

Abstract Volatility movements are known to be negatively correlated with stock index returns. Hence, investing in volatility appears to be attractive for investors seeking risk diversification. The most common instruments for investing in pure volatility are variance swaps, which now enjoy an active over-the-counter (OTC) market. This paper investigates the risk-return tradeoff of variance swaps on the Deutscher Aktienindex and Euro STOXX 50 index over the time period from 1995 to 2004. We synthetically derive variance swap rates from the smile in option prices. Using quotes from two large investment banks over two months, we validate that the synthetic values are close to OTC market prices. We find that variance swap returns exhibit an option-like profile compared to returns of the underlying index. Given this pattern, it is crucial to account for the non-normality of returns in measuring the performance of variance swap investments. As in the US, the average returns of selling variance swaps are found to be strongly positive and too large to be compatible with standard equilibrium models. The magnitude of the estimated risk premium is related to variance uncertainty and past index returns. This indicates that the variance swap rate does not seem to incorporate all past information relevant for forecasting future realized variance.
Has a structural break affected New Zealand business cycles

By international standards, New Zealand’s recent business cycle fluctuations are remarkably volatile. Some bivariate regularities observed in developed economies are weak and sometime uncertain. Are these features endemic to New Zealand’s economy or the result of structural disturbances of the seventies? The paper reports that there are distinct signs of some structural break in the seventies, but the qualitative features of the business cycle are similar before and after any possible break. The reasons of these peculiarities then are to be sought in New Zealand’s own economic institutions. Both authors are Senior Lecturers at the Department of Economics and Marketing, Lincoln University, New Zealand.
Abandoned object detection using multi-layer motion detection

Abandoned object detection (AOD) systems are required to run in high traffic situations, with high levels of occlusion. Systems rely on background segmentation techniques to locate abandoned objects, by detecting areas of motion that have stopped. This is often achieved by using a medium term motion detection routine to detect long term changes in the background. When AOD systems are integrated into person tracking system, this often results in two separate motion detectors being used to handle the different requirements. We propose a motion detection system that is capable of detecting medium term motion as well as regular motion. Multiple layers of medium term (static) motion can be detected and segmented. We demonstrate the performance of this motion detection system and as part of an abandoned object detection system.

Based on results analysis, it is concluded that there was an effect of project activity integration in Zoology of Vertebrate teaching and learning on pre-service teachers’ scientific process skill and self-efficacy, with significance level of 0.05.
Mapping the Cognitive Competencies of Street Vendors and Bus Conductors: A Cross-Cultural Study of Workplace Mathematics Mapeo de las competencias cognitivas de los vendedores ambulantes y los conductores de autobuses: Un estudio transcultural del lugar de trabajo de Matemáticas

This paper explores the mathematical ideas that emerge across two workplace settings, namely street vending and bus conducting. The purpose of this study was to delineate a trajectory describing potential mathematical structures underlying bus conducting and street vending activities and to extract a conceptual model that could explain the nature of the practitioners’ mathematical knowledge and its connection to formal mathematics. We conducted a meta-analysis of the problem solving behavior and narratives of street vendors and bus conductors in two geographic sites in Beirut, Lebanon and Chennai, India. Principled by Vergnaud’s theory of conceptual fields, the researchers examined heuristics-in-action that transpired as a result of practitioners’ engagement in their respective work situations.
Radiative Effects of Water Clouds on Heat, Cloud Microphysical and Surface Rainfall Budgets Associated with Pre-Summer Torrential Rainfall

This study investigates thermal, cloud microphysical and surface-rainfall responses to the radiative effects of water clouds by analyzing two pairs of two-dimensional cloud-resolving model sensitivity experiments of a pre-summer heavy rainfall event. In the presence of the radiative effects of ice clouds, exclusion of the radiative effects of water clouds reduces the model domain mean rain rate through the mean hydrometeor increase, which is associated with the decreases in the melting of graupel and cloud ice caused by enhanced local atmospheric cooling. In the absence of the radiative effects of ice clouds, removal of the radiative effects of water clouds increases model domain mean rain rate via the enhancements in the mean net condensation and the mean hydrometeor loss. The enhanced mean net condensation and increased mean latent heat are related to the strengthened mean infrared radiative cooling in the lower troposphere. The increased mean hydrometeor loss associated with the reduction in the melting of graupel is caused by the enhanced local atmospheric cooling.
