Geochemistry of the paleocene limestones of ewekoro formation, eastern Dahomey Basin, southwestern Nigeria: implication on provenance and depositional conditions

Thirty three limestone samples of the Paleocene Ewekoro Formation from exploratory drill cores within Ibeshe cement quarry, southwestern Nigeria were investigated for major, trace and rare earth elements abundances using inductively coupled plasma spectrometry (ICP-MS) analytical method. The aims were to investigate the depositional settings and source of rare earth element (REE). The major oxides concentration showed significant variations among the limestone facies. Higher SiO 2 , Al 2 O and Fe 2 O 3 contents were observed in the marly and sandy facies than the fossiliferous limestone, whereas the fossiliferous facies were enriched in CaO content. The trace elements content of the limestones normalized with the Post-Archean Australian Shale (PAAS) values revealed significant enrichment in Nb, Sr and U, whereas Ba, Th, Rb and other trace elements contents were depleted. The PAAS normalized REE + Y of the limestones displayed relatively uniform patterns of (i) slightly enriched LREE; (ii) positive Ce anomaly; (iii) positive Gd anomaly; (iv) positive Eu anomaly (v) high Y/Ho ratio. The characteristics non-seawater-like REE patterns, elevated ΣREE, high La N /Yb N ratios and high Y/Ho ratios, suggested that variations in REE contents were mainly controlled by the amount of terrigenous contaminations in the limestones. Ratios of La/Sc, La/Co, Th/Co, Th/Cr, Cr/Th and Th/Sc suggested that the terrigenous inclusions in these limestones were derived mainly from intermediate to felsic source rocks. The negative correlation of Sr with Mn and positive correlations of Eu with elements such as Zr, Y, Th and Hf suggested that the observed positive Eu anomalies in the limestones might be due to diagenetic processes. The geochemical parameters such as Ce anomaly, authigenic U, Mn*, V/(V+Ni), V/Ni ,Th/U ratios indicated that the limestones of Ewekoro Formation were deposited in restricted to open shallow marine environments under fluctuating oxidizing to anoxic conditions.

Nonstandard symmetry classes in mesoscopic normal-superconducting hybrid structures

Normal-conducting mesoscopic systems in contact with a superconductor are classified by the symmetry operations of time reversal and rotation of the electron’s spin. Four symmetry classes are identified, which correspond to Cartan’s symmetric spaces of type C, CI, D, and DIII. A detailed study is made of the systems where the phase shift due to Andreev reflection averages to zero along a typical semiclassical single-electron trajectory. Such systems are particularly interesting because they do not have a genuine excitation gap but support quasiparticle states close to the chemical potential. Disorder or dynamically generated chaos mixes the states and produces forms of universal level statistics different from Wigner-Dyson. For two of the four universality classes, the n-level correlation functions are calculated by the mapping on a free one-dimensional Fermi gas with a boundary. The remaining two classes are related to the Laguerre orthogonal and symplectic random-matrix ensembles. For a quantum dot with a normal-metal‐superconducting geometry, the weaklocalization correction to the conductance is calculated as a function of sticking probability and two perturbations breaking time-reversal symmetry and spin-rotation invariance. The universal conductance fluctuations are computed from a maximum-entropy S-matrix ensemble. They are larger by a factor of 2 than what is naively expected from the analogy with normal-conducting systems. This enhancement is explained by the doubling of the number of slow modes: owing to the coupling of particles and holes by the proximity to the superconductor, every cooperon and diffusion mode in the advanced-retarded channel entails a corresponding mode in the advanced-advanced ~or retarded-retarded! channel. @S0163-1829~97! 04001-0#
Mineral assemblages, stable isotopes and fluid inclusions in ore veins from the Macigno Formation at Calafuria (Livorno Mountains, northern Tuscany, Italy)

The present paper deals with an integrated geological, mineralogical and geochemical study on mineralized faults and fractures recognized in the Macigno Formation at Calafuria in the Livorno Mountains of northern Tuscany. In the field, two main different systems of faults were recognized: an earlier one related to a compressive phase with NE- SW, NW-SE and N-S trending faults, and a younger one related to a relaxation phase with reactivation of N-S and NW-SE trending faults. They distinguish for specifi c mineral assemblages, consisting mainly of quartz in the former, and barite-marcasite-pyrite in the latter. Minerals were analyzed for fl uid inclusions and isotopic composition. Data on fl uid inclusions indicate that three main mineralizing episodes affected the fault systems. In the fi rst episode, the fl uids deposited quartz in the fault systems related to the compressive phase. The second episode was the main one, and led to the deposition of euhedral quartz in the NE-SW faults, and barite, maracasite and pyrite essentially in the N-S and NW-SE faults. The fl uid evolution ended with the deposition of calcite, dolomite and a series of supergene minerals originated by alteration of Fe- sulfi des. The sulfur isotopic composition of minerals (-6.3 to 25.1‰) would seem to exclude a magmatic origin of the sulfur, favoring instead a sedimentary origin. Moreover, a temperature of about 400°C is estimated by sulfur isotope thermometry for the second stage of mineralization. Owing to pressure effects, the homogenization temperature given by the fl uid inclusions for this stage of mineralization is considerably lower that the isotopic one. A lithostatic pressure of 125 MPa is estimated for the barite and sulfi de mineralization, this corresponding to a depth of 5 km. Finally, a post-Middle Pliocene age is proposed for the ore veins at Calafuria, that may have formed during tectonic relaxation events from hydrothermal fl uids rich in CO2 and H2S, as are observed in the Larderello geothermal area at present.
Transient surface impedance (TranSIM) measurements using discrete lightning for electromagnetic mapping at audio frequencies

The paper describes the first field measurements using recently developed TranSIM instrumentation. The method is based on registering horizontal components of electric and magnetic field of distant lightning strokes (sferics). In fact it is an expansion of classical MT method in the VLF frequency range of 3 to 30 kHz thus providing information about conductivity distribution at the depths of approximately 50 to 300 meters. Measurements are conducted atop basalt body in the vicinity of Ipswich (Queensland) over 16 sites on 2 parallel profiles. From 20 to 50 sferics were registered at every site. Data was processed using short time Fourier transform obtaining spectrograms of electric and magnetic field. Apparent resistivity was calculated and frequency pseudo sections are presented. The apparent resistivity sections were matched with geological scheme of the site. Highly resistive zones correlate with high thickness of a basalt layer and conductive zones show where the underlying basalt sandstone is closest to the surface.
Top executive compensation in Portuguese family firms

Performance based compensation is considered a decisive tool in the co-alignment of interest between owners and managers. The solution to agency problems in public corporations hinges critically on the use of variable compensation mechanisms. Empirical analysis of this phenomenon is exiguous and the background theory has been suffering developments, like the introduction of family firm agency problems. This study confirms the larger use of variable compensation by public firms but shows that the potential for using variable compensation in second or third generation family firms is particularly high due to higher potential form conflict emergence between the different stakeholders. The framework used in this paper has the potential to encompass a wide range of phenomena where conflict can emerge and incentives can be used to co-align interests between the different transacting parties.
Growth Curve of Dairy Artificial Insemination Bulls Raised under Thai Tropical 1 Conditions 2 3

11 The objective of this research was to evaluate the growth curve of dairy artificial 12 insemination bulls under Thai tropical conditions. Data consisted of 4,963 monthly body 13 weights from 140 bulls from the Semen Production and Dairy Genetic Evaluation Center of 14 the Dairy Promotion Organization of Thailand collected from 1996 to 2015. Four breed 15 groups were defined based on Holstein (H) fraction: BG1 (0.96 ≤ H ≤ 1.00), BG2 (0.91 ≤ H < 16 0.96), BG3 (0.86 ≤ H < 0.91), and BG4 (0.44 ≤ H < 0.86). Linear (Quadratic) and nonlinear 17 (Gompertz, Logistic, Von Bertalanffy and Brody) models were compared for goodness of fit 18 using -2logL, Akaike Information Criterion (AIC), Corrected AIC (AICC) and Bayesian 19 Information Criterion (BIC). The model with the lowest values for these four criteria was 20 Quadratic. Predicted weights at 30 mo and 60 mo of age were higher for bulls in BG2 than 21 bulls in BG1, BG3, and BG4. Growth curves from these bulls would be useful to identify 22 sires expected to produce steers with faster growth rates and heifers with younger ages at first 23 calving. Unfortunately, weights from steer and heifer progeny from these bulls were 24 unavailable. Consequently, progeny weights would need to be collected if genomic selection 25 for growth traits were to be implemented in the Thai multibreed population. 26 27
The CAMELS-CL dataset : catchment attributes and meteorology for large sample studies – Chile dataset

The paper presents a newly available dataset for a region with limited prior data availability. The dataset combines a number 15 of hydrological, climatological, and geographical characteristics allowing for interesting synthesis of these data. I have learned a number of things about Chilean hydrology including regional aspects, even though this did not seem to be the focus of this paper. Another strong side of the paper is that authors clearly describe the limitations of the data and the implications. In my opinion, the paper is relevant for HESS audience, presents a valuable contribution to the field, so I recommend publication subject to addressing comments below. 20
New technique for dynamic closure of the abdominal wall Nova técnica para o fechamento dinâmico da parede abdominal

Advances in care of trauma patients and severe abdominal infections are responsible for an increasing number of laparostomies. The management of this entity is complex and several techniques have been described for its treatment. Recently the concept of dynamic closure of the abdominal wall was introduced in the literature with high success rates. The objective of this report is to serve as a foreword for a new approach for the treatment of laparostomy developed at the University Hospital of the University of São Paulo. This is a simple and low cost method, easily performed by a general surgeon. The procedure was also used prophylactically as reinforcement in tight abdominal closures. It is described in detail as well as the results in the first patients. Although promising, refinements and further studies are needed to validate the technique.
Literature, crisis, and Spanish rural space in the context of the 2008 financial recession

ABSTRACT The novelistic production related to the 2008 financial crisis has been partially studied from the lens of the label of “literatura de la crisis. ” In this article, I analyze the complex and essential transformations suffered by literary writing practices in contemporary Spain where ill attention has been devoted to the social, political, and aesthetic implications of neoliberal globalization in rural areas. Departing from a thorough conceptualization of the notion of “literatura de la crisis” and its paradoxical impact over the most recent literary production, I study the rural discourse and the emerging academic challenges for the assessment of the rural experience in literary works. In conclusion, I set the main principles for the development of a transposable model of textual analysis that will shed new light on the cultural representation of the rural sphere in the aftermath of the 2008 financial recession.
Modulation of phenotypic traits under different rearing temperatures: Experimental evidence in male guppy (Poecilia reticulata)

Climate change particularly global warming unceasingly imposes a selective pressure in many organisms that results in phenotypic plasticity particularly by expressing different adaptive phenotypes to shifting environmental conditions. The present study was, therefore, conducted to explore the phenotypic responses of male guppy ( Poecilia reticulata ), a popular model fish, to an ambient (28±0.91°C), high (32±0.12°C) and low (22±0.17°C) rearing temperature. Almost equal sized juvenile males were collected from the wild and reared up to 30 days maintaining necessary conditions similar among treatments except the water temperature. The findings revealed that high-temperature reared fish had significantly lower number of courtships, reduced survival, decreased body size, deformed body shape, limited colour patterns and reduced sperm bundle number than the ambient- and low-temperature groups. On the other hand, low-treatment males performed significantly higher number of courtships than ambient-temperature group, while ambient-temperature reared males possessed significantly higher body size and iridescent colour area than low- temperature treatment. Interestingly, the findings also revealed some trade-offs between traits under thermal-induced stressed conditions (i.e. both high and low temperatures). These findings elicit further information about the thermal condition dependent expression of phenotypic traits of fishes which infer about how fish species will adapt in the predicted changing aquatic environments because of unprecedented climate change.
Genetic Variation in Host-Specific Competitiveness of the Symbiont Rhizobium leguminosarum Symbiovar viciae

Legumes of the Fabeae tribe form nitrogen-fixing root nodules resulting from symbiotic interaction with the soil bacteria Rhizobium leguminosarum symbiovar viciae (Rlv). These bacteria are all potential symbionts of the Fabeae hosts but display variable partner choice when co-inoculated in mixture. Because partner choice and symbiotic nitrogen fixation mostly behave as genetically independent traits, the efficiency of symbiosis is often suboptimal when Fabeae legumes are exposed to natural Rlv populations present in soil. A core collection of 32 Rlv bacteria was constituted based on the genomic comparison of a collection of 121 genome sequences, representative of known worldwide diversity of Rlv. A variable part of the nodD gene sequence was used as a DNA barcode to discriminate and quantify each of the 32 bacteria in mixture. This core collection was co-inoculated on a panel of nine genetically diverse Pisum sativum, Vicia faba, and Lens culinaris genotypes. We estimated the relative Early Partner Choice (EPC) of the bacteria with the Fabeae hosts by DNA metabarcoding on the nodulated root systems. Comparative genomic analyses within the bacterial core collection identified molecular markers associated with host-dependent symbiotic partner choice. The results revealed emergent properties of rhizobial populations. They pave the way to identify genes related to important symbiotic traits operating at this level.
GAINING SUSTAINABLE COMPETITIVE IT ADVANTAGES: MULTIPLE CASE STUDIES IN INTERNATIONALIZED BUSINESSES

This research studies how the studied firms gain sustainable competitive advantages (SCAs). The issue has been studied in the literature on business strategy: the challenge for managers is to identify, develop, protect and use resources and skills that provide the firm with SCAs. Eight cases were studied. All concerned Information Technology firms that sell to other companies. The variables used were qualitative. Data was collected from primary and secondary sources of information. The primary sources consisted of the studied firms, where interviews with management were held. The main results are: (1) One firm develops products abroad and this aspect is a competitive advantage. (2) There are cases that resort to a model that provides them with great operating flexibility. (3) One firm obtained SCAs by developing a strategy whereby it implemented a franchise model for development and distribution. The franchise system encourages entrepreneurial behavior among the franchisees. (4) One case gained a competitive advantage through the complexity and sophistication of its products. (5) Some of the cases searched for market niches that were less exposed to competition. Key-words: Strategic management. Strategic planning. Advanced Technology firms. Management of multinationals.

On the Use of Conformal Models and Methods in Dosimetry for Nonuniform Field Exposure

Numerical artifacts affect the reliability of computational dosimetry of human exposure to low-frequency electromagnetic fields. In the guidelines of the International Commission of Non-Ionizing Radiation Protection (ICNIRP), a reduction factor of 3 was considered to take into account numerical uncertainties when determining the limit values for human exposure. However, the rationale for this value is unsure. The IEEE International Committee on Electromagnetic Safety has published a research agenda to resolve numerical uncertainties in lowfrequency dosimetry. For this purpose, intercomparison of results computed using different methods by different research groups is important. In previous intercomparison studies for low-frequency exposures, only a few computational methods were used, and the computational scenario was limited to a uniform magnetic field exposure. This study presents an application of various numerical techniques used: different Finite Element Method (FEM) schemes, Method of Moments (MoM) and Boundary Element Method (BEM) variants and finally by using a hybrid FEM/BEM approach. As a computational example, the induced electric field in the brain by the coil used in transcranial magnetic stimulation is investigated. Intercomparison of the computational results are presented qualitatively. Some remarks are given for the effectiveness and limitations of application of the various computational methods.

Self-reliance

This study examines the extent to which family environment influences children’s behavior and how an evening of parents serves as a platform for rehabilitating the family environment, preventing and decreasing street children's number. This descriptive study intends to create awareness of the prevention and reintegration of street children. Researchers purposively selected 58 respondents: 40 street children, 12 parents, and 6 local leaders. Data were collected through interviews, storytelling, and focus group discussions and qualitatively analyzed using content analysis. Results revealed domestic violence, identity crisis, born from sex workers, children abuse, poor parenting, and poverty to be factors contributing to street children as emphasized by 100% of children, 87% of local leaders, and 67% of parents. Street children can only be controlled if major stressors that push them to develop self-reliance are socially and economically addressed. It was revealed that the Evening of Parents is a platform of family transformation to successfully prevent and rehabilitate street children focusing on parents’ responsibilities towards children’s wellbeing and better future.
Efficient Mapping Space Exploration for a Reconfigurable Neural Accelerator

Deep learning accelerators have emerged to enable energy-efficient and high-throughput inference from edge devices such as self-driving cars and smartphones, to data centers for batch inference such as recommendation systems. However, the actual energy efficiency and throughput of a deep learning accelerator depends on the deep neural network (DNN) loop nest mapping on the processing element array of an accelerator. Moreover, the efficiency of a mapping dramatically changes by the target DNN layer dimensions and available hardware resources. Therefore, the optimal mapping search problem is a non-trivial high-dimensional optimization problem. Although several tools and frameworks exist for compiling to CPUs and GPUs, we lack similar tools for deep learning accelerators. To deal with the optimized mapping search problem in deep learning accelerators, we propose mRNA (mapper for reconfigurable neural accelerators), which automatically searches optimal mappings using heuristics based on domain knowledge about deep learning and an energy/runtime cost evaluation framework. mRNA targets MAERI, a recently proposed opensource deep learning accelerator that provides flexibility via reconfigurable interconnects, to run the unique mappings for each layer generated by mRNA. In realistic machine learning workloads from MLPerf, the optimal mappings identified by mRNA framework provides 15% to 26% lower runtime and 55% to 64% lower energy for convolutional layers and 24% to 67% lower runtime and maximum 67% lower energy for fully connected layers compared to simple reference mappings manually picked for each layer.
Epidemiology and control of Spongospora subterranea f . sp . subterranea , with special reference to zoospore release and bait plant infection

Presently, there are no adequate control measures for powdery scab, and this situation is aggravated by the widespread cultivation of susceptible varieties. New control measures are urgently needed. Environmental conditions have been reported to greatly influence the incidence and severity of powdery scab (Harrison et al., 1997), and more basic knowledge on survival of this persistent pathogen is needed to optimise disease prevention and control.
A 14C Calibration with AMS from 3500 to 3000 BC, Derived from A New High-Elevation Stone-Pine Tree-Ring Chronology

High-precision radiocarbon accelerator mass spectrometry (AMS) measurements of a new high-altitude stone-pine tree-ring chronology from the European Alps were performed for a 500-yr stretch in the second half of the 4th millennium BC. A 14C calibration curve with a typical 1-σ uncertainty of about 20 14C yr was achieved. Although the general agreement of our data set with INTCAL98 is very good (confirming once more that INTCAL98 is also proper for calibration of samples of extraordinary sites), we found small deviations of 17 ± 5 14C yr, indicating possible seasonal effects of the delayed growing season at high altitude.
