A New Approach for Permeability Prediction With NMR Measurements in Tight Formations
Authors: Di Jianwei , Jensen Jerry L. 
Published: April 2016

Summary
Prediction of extremely low permeability in tight reservoirs poses major challenges with traditional methods. Several studies have proposed nuclear magnetic resonance (NMR) permeability predictors, but these often give large errors when applied in tight formations. In this report, we describe a new method with NMR well-log measurements that decomposes the T2 spectrum into, at most, three Gaussian components. On the basis of parameters from the decomposition, we build a pore-size-based lithofacies model to predict whole-core horizontal permeability. With these parameters, we also modify the empirical Timur-Coates equation (TIM) to predict permeability.
The NMR decomposition allows us to predict proportions of shale and silt. Applied to the tight Cardium formation, the parameters correlate strongly with core image and X-Ray-diffraction (XRD) results. In addition to Cardium data, we apply our approach to published data sets with good results, showing that the model gives accurate lithofacies-proportion estimates.
To calibrate the model, Cardium probe permeameter data are used to identify facies permeabilities. Arithmetic-averaged permeability with the NMR-based model was calculated to compare with whole-core horizontal permeability. Monte Carlo analysis confirms the agreement between the model and core-permeability values. Our model provides a “bridge” to relate permeability between the probe scale (&lt;1 cm laminations) and core size (&gt;15 cm thin beds).
Without the NMR well-log decomposition, Cardium TIM permeability predictions are in error by more than one order of magnitude in most intervals. The major challenge with the TIM model is obtaining an accurate T2 cutoff value. Compared with core-measured bound-water saturations, the default 33 ms value is too large for our tight samples. Our NMR decomposition, however, shows good correlation with measured bound-water saturations. With several core samples and NMR parameters, we modified the TIM model and found that it provides very good permeability predictions.

Background and objectives
Carotid intima-media thickness has been reported to predict kidney function decline. However, whether carotid intima-media thickness is associated with a hard kidney end point, ESRD, has not been investigated.

Design, setting, participants, & measurements
We studied 13,197 Atherosclerosis Risk in Communities participants at visit 1 (1987–1989) without history of cardiovascular disease, including coronary heart disease, stroke, and heart failure, at baseline and assessed whether carotid intima-media thickness measured by B-mode ultrasound is associated with ESRD risk using Cox proportional hazards models. Regarding carotid intima-media thickness parameters, we investigated the mean and maximum values of overall and segment-specific (common, bifurcation, and internal carotid arteries) measurements.

Results
Mean age was 54.0 (SD=5.7) years old, and there were 3373 (25.6%) blacks and 7370 (55.8%) women. During a median follow-up of 22.7 years, 433 participants developed ESRD (1.4/1000 person-years). After adjusting for shared risk factors for atherosclerosis and kidney disease, including baseline kidney function, carotid intima-media thickness was significantly associated with ESRD risk (hazard ratio [HR] between quartiles 4 and 1, 1.46; 95% confidence interval [95% CI], 1.02 to 2.08 for overall mean intima-media thickness and HR between quartiles 4 and 1, 1.75; 95% CI, 1.24 to 2.48 for overall maximum intima-media thickness). The associations were largely consistent in demographic and clinical subgroups. When we explored segment–specific intima-media thicknesses, the associations with ESRD were most robust for bifurcation carotid (e.g., adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 1.49; 95% CI, 1.04 to 2.13 for bifurcation; adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 1.36; 95% CI, 0.94 to 1.97 for common; and adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 0.93; 95% CI, 0.67 to 1.29 for internal).

Conclusions
Carotid intima-media thickness was independently associated with incident ESRD in the general population, suggesting the shared etiology of atherosclerosis and ESRD.

ABSTRACT
We present the discovery in Kepler’s K2 mission observations and our follow-up radial velocity (RV) observations from Keck/HIRES for four eclipsing binary (EB) star systems in the young benchmark Pleiades and Hyades clusters. Based on our modeling results, we announce two new low mass (

) EBs among Pleiades members (HCG 76 and MHO 9) and we report on two previously known Pleiades binaries that are also found to be EB systems (HII 2407 and HD 23642). We measured the masses of the binary HCG 76 to ≲2.5% precision, and the radii to ≲4.5% precision, which together with the precise effective temperatures yield an independent Pleiades distance of 132 ± 5 pc. We discuss another EB toward the Pleiades that is a possible but unlikely Pleiades cluster member (AK II 465). The two new confirmed Pleiades systems extend the mass range of Pleiades EB components to 0.2–2

. Our initial measurements of the fundamental stellar parameters for the Pleiades EBs are discussed in the context of the current stellar models and the nominal cluster isochrone, finding good agreement with the stellar models of Baraffe et al. at the nominal Pleiades age of 120 Myr. Finally, in the Hyades, we report a new low mass eclipsing system (vA 50) that was concurrently discovered and studied by Mann et al. We confirm that the eclipse is likely caused by a Neptune-sized transiting planet, and with the additional RV constraints presented here we improve the constraint on the maximum mass of the planet to be ≲1.2 M

Published: April 2016

The ant fauna of Greek Thrace has been least known of all Greek regions with only 12 species mentioned in the literature. We conducted two field trips to this region in 2014 and 2015 and included some unpublished ant material, thus compiling new records from 72 sampling localities.
We found 115 ant species, 108 of them are recorded for the first time in Greek Thrace. Cataglyphis viaticoides, Temnothorax aeolius, Tetramorium cf. davidi, Tetramorium hippocratis, and Tetramorium rhodium were so far not known for continental Greece. In the checklist of recorded species, we also give information on the taxonomic status and distribution of certain taxa.

Published: April 2016

En 1939, l’arrivée soudaine et massive de 500000 Espagnols venus chercher refuge en France suscite autant le rejet que la solidarité. L’« accueil » qui leur est fait illustre les revirements politiques des gouvernements successifs en matière d’asile et inaugure une ère de camps dont ceux de Calais et de Grande-Synthe ne sont que le prolongement près de trois quarts de siècle plus tard.
Les fêtes politiques de la Deuxième République en Alsace (1848-1852)
Authors: Igersheim François 
Published: April 2016

Les périodes révolutionnaires concentrent les moments d’extériorisation d’émotions politiques collectives qui peuvent prendre le nom de fêtes. Ils sont particulièrement abondants sous la Deuxième République. Les députés orléanistes honnis font l’objet de charivaris, comme à Strasbourg en février 1848. L’opposition se réunit en banquets républicains, à Colmar et à Strasbourg en 1847. Puis en février, c’est l’explosion ; plus d’une centaine de localités alsaciennes sont le théâtre d’émeutes, avec parfois la plantation d’arbres de la liberté, et aussi l’excès de la persécution anti‑juive. Les nouveaux dirigeants républicains entendent contrôler ces mouvements et décide de la célébration de Fêtes officielles dans les chef-lieux, à Strasbourg et à Colmar puis dans de nombreuses petites villes avec plantation d’arbres de la liberté et fraternisations entre soldats et gardes nationaux, patrons et ouvriers etc. La politique reprend ses droits et les campagnes électorales voient réapparaître les banquets. Mais les démocrates-sociaux (rouges) inventent aussi le grand meeting populaire de plein air, comme pendant la campagne électorale de 1849. En Alsace, ils l’emportent sur les partis modérés jusqu’en 1851. En 1850, le voyage présidentiel entre dans le registre de la célébration publique, à Mulhouse, à Colmar, à Strasbourg et dans les localités du parcours. À partir du coup d’État militaire du 2 décembre, à la fête politique succède une « fête nationale » tout aussi politique, où le spectacle est celui de la force armée en revue, particulièrement importante dans une Alsace qui concentre de nombreuses garnisons.
Strict Comparison of Positive Elements in Multiplier Algebras
Authors: Kaftal Victor , Wong Ng Ping , Zhang Shuang 
Published: April 2016

AbstractMain result: If a C*-algebrais simple,σ-unital, hasfinitely many extremal traces, and has strict comparison of positive elements by traces, then its multiplier algebraalso has strict comparison of positive elements by traces. The same results holds if finitely many extremal traces is replaced byquasicontinuous scale. A key ingredient in the proof is that every positive element in the multiplier algebra of an arbitrary σ-unital C* -algebra can be approximated by a bi-diagonal series. As an application of strict comparison, ifis a simple separable stable C* -algebra with real rank zero, stable rank one, and strict comparison of positive elements by traces, then whether a positive element is a positive linear combination of projections is determined by the trace values of its range projection.
Non-deforestation fire vs. fossil fuel combustion: the source of CO2 emissions affects the global carbon cycle and climate responses
Authors: Landry Jean-Sébastien , Matthews H. Damon 
Published: April 2016

Abstract. Non-deforestation fire – i.e., fire that is typically followed by the recovery of natural vegetation – is arguably the most influential disturbance in terrestrial ecosystems, thereby playing a major role in carbon exchanges and affecting many climatic processes. The radiative effect from a given atmospheric CO2 perturbation is the same for fire and fossil fuel combustion. However, major differences exist per unit of CO2 emitted between the effects of non-deforestation fire vs. fossil fuel combustion on the global carbon cycle and climate, because (1) fossil fuel combustion implies a net transfer of carbon from geological reservoirs to the atmospheric, oceanic, and terrestrial pools, whereas fire occurring in terrestrial ecosystems does not; (2) the average lifetime of the atmospheric CO2 increase is longer when originating from fossil fuel combustion compared to fire, due to the strong vegetation regrowth following fire disturbances in terrestrial ecosystems; and (3) other impacts, for example on land surface albedo, also differ between fire and fossil fuel combustion. The main purpose of this study is to illustrate the consequences from these fundamental differences between fossil fuel combustion and non-deforestation fires using 1000-year simulations of a coupled climate–carbon model with interactive vegetation. We assessed emissions from both pulse and stable fire regime changes, considering both the gross (carbon released from combustion) and net (fire-caused change in land carbon, also accounting for vegetation decomposition and regrowth, as well as climate–carbon feedbacks) fire CO2 emissions. In all cases, we found substantial differences from equivalent amounts of emissions produced by fossil fuel combustion. These findings suggest that side-by-side comparisons of non-deforestation fire and fossil fuel CO2 emissions – implicitly implying that they have similar effects per unit of CO2 emitted – should therefore be avoided, particularly when these comparisons involve gross fire emissions, because the reservoirs from which these emissions are drawn have very different residence times (millions of years for fossil fuel; years to centuries for vegetation and soil–litter). Our results also support the notion that most net emissions occur relatively soon after fire regime shifts and then progressively approach zero. Overall, our study calls for the explicit representation of fire activity as a valuable step to foster a more accurate understanding of its impacts on global carbon cycling and temperature, as opposed to conceiving fire effects as congruent with the consequences from fossil fuel combustion.
Investigation and Prioritizing the Effective Factors on Increasing the Human Resources Productivity in Agriculture Bank Using Multi-Attribute Decision Making Model
Authors: Abachi Amir 
Published: April 2016

As organizations are going to develop, the need for efficient manpower becomes more apparent. Obviously, productivity of the manpower requires the attention of managers to the complexity of human behavior and appropriate utilization of the principles, techniques and skills of the management. This study aims to prioritize the effective factors on productivity of human resources in the Agriculture Bank. Productivity is beyond the performance, it also contains the effectiveness concept, and in other words, productivity is not just doing the right things. An activity may be done correctly and in the best way, while it has no role in achieving the goal. In this case, the performance is available but there is no productivity. Difference between the performance and is rooted in the effectiveness or in the direction of doing a work. The current paper is a descriptive survey. Statistical population includes all experts in the Research and Strategic Planning center of the Agricultural Bank (33 persons). The data obtained from the questionnaire were analyzed using descriptive statistics in the form of frequency table. Questions were examined based on the one-group- t-test and using SPSS. Effective factors on increasing the human resources productivity were prioritized using Multi- Attribute Decision Making (MADM). After comparison of the alternatives, the related tables were prepared and prioritizing or ranking were done by determining the weight of each factor indexes and finally determining the weight of the four main factors. TOPSIS was used to evaluate the results of the MADM. Our research aims to prioritize the four factors according to the MADM.

<p>Olive trees have the capability of growing under semi-arid regions, where drought and salinity are the major concerns. Two years field experiments were carried out to investigate the interaction effects of natural saline well water and irrigation levels on the quantity and quality of fatty acids in the olive flesh fruits (“Roghani” cultivar). A factorial layout within a randomized complete blocks design with three replications of five irrigation levels (I<sub>1</sub> to I<sub>5</sub> as 0.25, 0.5, 0.75, 1 and 1.25 ET<sub>c</sub>) and three saline water levels (S<sub>1</sub> to S<sub>3</sub> as 100%WW, 50%WW+50%FW and 100%FW) were considered. The fresh and brackish irrigation water were withdrawn from two different natural wells (fresh water (FW) and saline water wells (WW)). <em>Results revealed that <strong>increasing salinity and decreasing irrigation water levels caused significant increment in the ratio of unsaturated fatty acids, palmitic acid to the percentage of oil and oil percentage in olive flesh fruit</strong></em>. It is found that as water<em> </em>salinity increased from lowest to the highest level, the oleic acid trends to its highest value of 23.68% in I<sub>1</sub>S<sub>1</sub>. Mean values of palmitic acid in 2013 were 27.52% and decreased to 19% in 2014. <em>It is concluded that highest percentage of oleic, linoleic, linolenic and palmitic acids obtained under high saline and less applied irrigation treatment (S<sub>1</sub>I<sub>2</sub>) yielding to improve the olive oil quality.</em></p>

Published: April 2016

The aim of this study was to evaluate the psychometric properties of the Coping Strategies Inventory (CSI) in a sample of 243 older people age 55 to 99 years old. The first order factorial structure was similar to the structure of the original version of the CSI and to the Spanish adaptation with general population. Furthermore high levels of internal consistency and of convergent validity were observed in the different primary scales. Nevertheless the problem avoidance scale did not surpass the validity and reliability tests. Due to it we propose to delete two of the items of this scale. On the other hand, in this study we confirmed the secondary and tertiary structure obtained in the original version of the inventory that was neither confirmed in the Spanish adaptation study nor the other studies on the psychometric properties of the Spanish version of the CSI.
Ultrasensitive mass sensing method based on slow light in cavity optomechanics
Authors: He Yong , Jiang Meiping 
Published: April 2016

Abstract
We present a novel approach using an ultrasensitive mass sensor to evaluate adsorbed mass in cavity optomechanics. The group delay of a transmitted signal field pulse can be adjusted by varying the optomechanical cooperativity, which depends on the effective mass of a mechanical resonator. We derive the linear relationship between the group delay and the adsorbed mass, and define the mass sensitivity of the proposed mass sensor. The results show that the mass sensitivity is determined by the temporal resolution of the evolution of the transmitted signal field pulse. Finally, we demonstrate a mass sensor at the attogram scale for measuring gold nanoparticles.
Effect of wall potential on morphology of symmetric diblock copolymers in nanotrench

Published: April 2016

Abstract
We have investigated the morphology of symmetric poly(styrene-b-methyl methacrylate) (PS-b-PMMA) diblock copolymers in narrow trenches by performing Monte Carlo (MC) simulations. We considered two types of interactions between the PMMA-attractive trench walls and the PS-b-PMMA. First, an exponential-type wall potential was applied to the PMMA segments to attract them to the wall, which has been widely used for the coarse-grained MC model. In the second case, only the PMMA blocks initially located near the trench wall were adsorbed to the wall. In both cases, the number of the PMMA lamellae was step-wisely increased each time the trench was widened by ∼1.0L
0 (L
0: lamellae period in the bulk). However, due to its considerably thin PMMA layer, the trench width in the second case had ∼0.7L
0 offset from that in the first case. These results imply the importance of interfacial characterization between the diblock copolymers and the trench walls.
AS MOTIVAÇÕES PARA DEIXAR DE SER INTRAEMPREENDEDOR E SE TORNAR EMPRESÁRIO.

Summary: Some companies seek to retain the most talented employees by giving them the opportunity to become intrapreneurs and develop their ideas without having to leave the company. Despite the incentives and freedom, not all employees want to become intrapreneurs and end up leaving their jobs to form their own businesses. The purpose of this paper is to present a case of a company that has taken advantage of this phenomenon to use their intrapreneurs as a way to expand the business turning them into entrepreneurs of their own businesses. In this research, the studied company operates in the tourism sector and is entrepreneurial oriented. We analyzed the trajectory of five of its former employees who set up their own businesses connected to the employer business. The results indicate that even with an organizational environment that fosters the entrepreneurial spirit in people, organizations need to admit that the business itself is the natural way of their best intrapreneurs. Rather than lose these employees, to encourage them to create new companies directly or indirectly linked to the organization's business can be a good way to reinvent organizational structures through the creation of a network of companies created by former employees that we call here External Entrepreneurial Orientation.Keywords: intrapreneurship, Entrepreneurial orientation, Entrepreneurship, New business creation, entrepreneurial profile, Organizational Innovation, Corporate Entrepreneurship.
