The complex exposure histories of the Pitts and Horse Creek iron meteorites: Implications for meteorite delivery models

Abstract— The concentrations of cosmogenic radionuclides and noble gases in Pitts (IAB) and Horse Creek (ungrouped) provide unambiguous evidence that both irons have a complex exposure history with a first‐stage irradiation of 100–600 Myr under high shielding, followed by a second‐stage exposure of ˜1 Myr as small objects. The first‐stage exposure ages of ˜100 Myr for Horse Creek and ˜600 Myr for Pitts are similar to cosmic‐ray exposure ages of other iron meteorites, and most likely represent the Yarkovsky orbital drift times of irons from their parent bodies in the main asteroid belt to one of the nearby chaotic resonance zones. The short second‐stage exposure ages indicate that collisional debris from recent impact events on their precursor objects was quickly delivered to Earth. The short delivery times suggests that the recent collision events occurred while the precursor objects of Horse Creek and Pitts were either very close to the chaotic resonance zones or already in Earth‐crossing orbits. Since the cosmogenic noble gas records of Horse Creek and Pitts indicate a minimum radius of a few meters for the precursor objects, but do not exclude km‐sized objects, we conclude that these irons may represent fragments of two near‐Earth asteroids, 3103 Eger and 1986 DA, respectively. Finally, we used the cosmogenic nuclide concentrations in Horse Creek, which contains 2.5 wt% Si, to test current model calculations for the production of cosmogenic 10Be, 26Al, and neonisotopes from iron, nickel, and silicon.

Modeling, Control and Power Management Strategy of a Grid connected Hybrid Energy System

This paper presents the detailed modeling of various components of a grid connected hybrid energy system (HES) consisting of a photovoltaic (PV) system, a solid oxide fuel cell (SOFC), an electrolyzer and a hydrogen storage tank with a power flow controller. Also, a valve controlled by the proposed controller decides how much amount of fuel is consumed by fuel cell according to the load demand. In this paper fuel cell is used instead of battery bank because fuel cell is free from pollution. The control and power management strategies are also developed. When the PV power is sufficient then it can fulfill the load demand as well as feeds the extra power to the electrolyzer. By using the electrolyzer, the hydrogen is generated from the water and stored in storage tank and this hydrogen act as a fuel to SOFC. If the availability of the power from the PV system cannot fulfill the load demand, then the fuel cell fulfills the required load demand. The SOFC takes required amount of hydrogen as fuel, which is controlled by the PID controller through a valve. Effectiveness of this technology is verified by the help of computer simulations in MATLAB/SIMULINK environment under various loading conditions and promising results are obtained.
Time-Varying Inflation Risk and Stock Returns Martijn Boons

We show that inflation risk is priced into stock returns and that inflation premia in the cross section and the aggregate market vary over time—even changing sign, as in the early 2000s. This time variation is due to both price and quantities of inflation risk changing over time. Using a consumption-based asset pricing model, we argue that inflation risk is priced because inflation predicts real consumption growth. The historical changes in this predictability and in stocks' inflation betas can account for the size, variability, predictability, and sign reversals in inflation risk premia.
Bayesian methodology for structural damage identification and reliability assessment.

A Bayesian framework is presented for structural model selection and damage identification utilizing measured vibration data. The framework consists of a two-level approach. At the first level the problem of estimating the free parameters of a model class given the measured data is addressed. At the second level the problem of selecting the best model class from a set of competing model classes is addressed. The application of the framework in structural damage detection problems is then presented. The structural damage detection is accomplished by associating each model class to a damage location pattern in the structure, indicative of the location of damage. Using the Bayesian model selection framework, the probable damage locations are ranked according to the posterior probabilities of the corresponding model classes. The severity of damage is then inferred from the posterior probability of the model parameters corresponding to the most probable model class. Computational issues are addressed related to the estimation of the optimal model within a class of models and the optimal class of models among the alternative classes. Asymptotic approximations as well as Monte Carlo simulations are used for estimating the probability integrals arising in the formulation. The framework can be used for assessing the reliability of structures based on the measured vibration data. The proposed methodology is illustrated by applying it to the identification of the location and severity of damage of a laboratory small-scaled bridge using measured vibration data.

A Review on Policy Change for Climate Change in Ethiopia

For ever and a day, the Troposphere climate has changing but because of human being involvement it is now changing in advance than it has for thousands of years. The reviews summarized works carried out on policy change for climate change in Ethiopian context. So, the main objectives of this paper was Identifying what climate change combating strategies have been developed and implemented, against climate change in Ethiopia. To end the objective all necessary secondary sources were reviewed. Finally it was founded that, Climate change is one of the key problem of our time that create great pressure to our societies. Likely Ethiopia has been identified as one of the country’s most susceptible to severe climate . This, severe climate (like, flood and drought) have deep negative influence on agricultural production, which have been a big impediment to the country’s economic growth. The incidence of droughts and floods has been identified to lessen growth potential of Ethiopia by more than one third. The Ethiopian Government has put in place combating strategies targeted at reducing the susceptibility of the country to climate change. Unlike the case of industrial countries which are required to alleviate their greenhouse gas emissions, the tangible measure needed from Ethiopia is to adapt to and lessen the influence of climate change through having development responsive national strategies and practical adaptation and mitigation measures.

Factors Affecting Electronic Medical Record Acceptance by Specialist Physicians

 Abstract—An Electronic Medical Record (EMR) is a longitudinal record of a patient consisting of data owned by a single provider, Generated as by-product of daily Health Information System (HIS) functions, an EMR provides caregivers with immediate access to information relevant to that patient, impacting care and safety in real time. Physicians’ acceptance and willingness must be present in order to successfully implement an EMR system; understanding Physicians’ attitudes and perceptions are of vital importance to physicians' acceptance and willingness. The main objective of this research is to explore physicians, attitude and perceptions of the impact on EMRs. The crosssectional study was conducted on 133 specialist physicians of Hormozgan Medical Sciences University in 3 educational hospitals in the city of Bandar Abbas capital city of Hormozgan province. The most important barrier factors of EMRs in this study were technical barriers such as limitation of the system 96 (72.2%) and interconnectivity/standardization96 (72.2%) and social factor of uncertainly about vendor 97 (72.9%), that mentioned by majority of physicians. This finding will help to address the barrier more appropriately, and plan for implementation EMRs. With peak interest in implementing EMR, in Iran and worldwide, knowing and acting on the beliefs associated with physicians about this technologies is as essential as ever.

Hanged for a Sheep: The Economics of Marginal Deterrence

SUPPOSE the highest punishment imposed in a particular legal system is life imprisonment. Someone suggests that perpetrators of armed robbery, a particularly dangerous and unpleasant crime, deserve that punishment. From the standpoint of traditional legal scholarship, this proposal raises a variety of issues having to do with the justice of the punishment. From the standpoint of the economic analysis of law, it raises a much simpler question: do we want to make it in the interest of armed robbers to kill their victims? In thinking about an economically efficient set of criminal punishments, we usually start by considering a single crime and trying to find the optimal way of inducing potential offenders not to commit it.2 This article is concerned with a problem one step more complicated-the situation in which a potential offender, if he commits an offense, will be choosing among two or more different crimes.3 If he commits one crime, he cannot (or, in more elaborate versions, is less likely to) commit the other. In such a situation, one of the considerations in setting punishments is the
Testing for Change in Stochastic Volatility with Long Range Dependence

In this paper, change-point problems for long memory stochastic volatility models are considered. A general testing problem which includes various alternative hypotheses is discussed. Under the hypothesis of stationarity the limiting behavior of CUSUM- and Wilcoxon-type test statistics is derived. In this context, a limit theorem for the two-parameter empirical process of long memory stochastic volatility time series is proved. In particular, it is shown that the asymptotic distribution of CUSUM test statistics may not be affected by long memory, unlike Wilcoxon test statistics which are typically influenced by long range dependence. To avoid the estimation of nuisance parameters in applications, the usage of self-normalized test statistics is proposed. The theoretical results are accompanied by simulation studies which characterize the finite sample behavior of the considered testing procedures when testing for changes in mean, in variance, and in the tail index.
The long-run relationship between production and external trade of basic metals division in Serbia

Being the major foreign exchange earner basic metals division is without a doubt an important manufactory division for Serbia. Given the importance of the industry cointegration and error correction techniques were used to estimate the long-run relationship between monthly external trade and production of basic metals. Both the long-run and short-run results indicate that external trade is positively related with production. Contrary to expectations, import was found to have a positive relationship with production. Furthermore, production and export of this division are increasingly import dependent, especially upon raw materials.
Role of Resistant Starches Particularly Rice Containing Resistant Starches in Type 2 Diabetes

Abstract Non-insulin-dependent or type 2 diabetes mellitus is on the rise in India particularly in the affluent urban and rural population. The exact cause is unknown. Malnutrition, defective intake of essential fatty acids and reduced intake of fibres are found in Indian diet, particularly rural Indian diet and the dietary factors may be one of the causes leading to increased incidence of the disease. Dietary fibers reduce blood glucose and cholesterol levels. Resistant starches behave as dietary fiber. As rice is the staple food in Indian villages, to increase the fibre consumption, a special variety of rice is processed which contains more of resistant starch. The high protein efficiency ratio (PER) in rice is presumably due to the balance of essential amino acids in rice protein. This high resistant starch containing rice was fed to diabetic patients for three months and effects observed. Results showed that total cholesterol, fasting blood sugar, low-density lipoprotein cholesterol were reduced while other parameters showed no significant changes.
Customers satisfaction with ATM banking in Malawi

Automated Teller Machine (ATM) banking is the second popular access channel to banking services behind branch banking in Malawi which offers competitive advantage in the homogenous market of retail banking products and services. It is important that banks achieve service quality and customer satisfaction to remain competitive through ATMs. The results are from 353 ATM card users where over half are satisfied with ATM services from their respective banks. All the ATM service attributes within the five service quality dimensions are important to ATM service users but performance is perceived good in ATM technology related attributes and poor in employee and management functionality related attributes. The results have further found that all service quality dimensions significantly correlate with customers satisfaction with ATM services and that reliability is the most important dimension followed by responsiveness, empathy, assurance and tangibles are the least important dimension agreeing with previous studies by Berry et al., Parasuraman et al. and Zeithmal et al. However, not all service quality attributes rated important by users contributed to their satisfaction. Therefore, the results designate that for banks to remain competitive through ATM banking efforts should be exerted in providing responsive ATM services. Further investment in newer ATM technologies may have marginal returns in creating competitive advantage since all banks are installing newer ATM technologies that enhance functionality and reliability of ATMs but differences are in the provision of responsive services that augment the ATM services provision. Keywords: Customers’ satisfaction, ATMs, service quality.
Influence of Heat on Seed Germination of the Three Acacia Species in the Sudan

The influence of temperature (dry heat) and electric burner on germination of Acaciasenegal, Acacia mellifera and Acacia laeta in Sudan was analyzed, in order to know the response of acacia seeds to dry heat treatments. Germination tests were carried out in plastic Petri dishes over 30 days. In general, the degree of seed germination promotion by dry heat treatments showed slight variation, the final germination level was not increased in all the studied species compared with the control with some exception. The thermal pretreatment with 45° C was not effective for the germination in Acacia senegal and Acacaia mellifera irrespective of heat exposure duration with the exception of Acacia laeta (North Kordofan, 20.25%). The germination rates after preheating were much lower than in mechanically scarified seeds by electric burner and closely resembled those of the untreated seeds, except for Acacia laeta (Gedarif), where it is t50 reached 11 days for temperature 45° C at two seconds. The response of these species to heat shock had no clear effects on germination.
Detection of low-dimensional chaos in drill bit torsional vibration time series

The near-bit strap-down measurement-while-drilling (MWD) system has been developed in this paper. By means of triaxial magnetometers, calculation method for bit rotational velocity was developed to monitor the drill bit torsional vibration. A number of techniques were applied to perform a nonlinear analysis of the experimental data of torsional vibration. Estimate delay time with mutual information and calculated the embedding dimension through Cao’s method, after reconstruct the phase space, the chaotic characteristics of the system were analyzed by calculating the correlation dimension and the largest Lyapunov exponent. We show that the largest Lyapunov exponent is positive and the correlation dimension is more than two, which is a strong indicator for the chaotic behaviour of the system. We also found that chaotic characteristics of the drill bit torsional vibration even existed in the whole drilling process, and thus the techniques based on phase space dynamics can be used to analyze and to predict drill bit torsional vibration. The results of this paper are of interest to applied and theoretical mechanics and petroleum engineering.
Regeneration from embryogenic callus and suspension cultures of the wild medicinal plant Cymbopogon schoenanthus

Somatic embryogenesis and plant regeneration from both callus and suspension cultures of the wild medicinal plant Cymbopogon schoenanthus subsp. proximus has been achieved. The species is rare and confined in its distribution to Africa. A range (0.5 to 8 mg/l) of 2,4-dichlorophenoxyacetic acid (2,4D) for the induction of embryogenic callus from seed cultures were used. Results show that 1.0 and 4.0 mg/l 2,4-D gave a 90 to 100% frequency of embryogenic callus containing mature embryos within three months of culture. Testing the effect of phosphorus and nitrogen concentrations on somatic embryogenesis from callus cultures showed that high phosphorus and low nitrogen concentrations enhanced embryo induction. Low NH4NO3 enhanced growth and maturation of somatic embryos, while low KNO3 enhanced germination and shoot production. Suspension cultures were initiated from embryogenic callus on 0.5, 1.0 and 2.0 mg/l 2,4-D, then plated on 3 different combinations of 2,4-D and 6-benzyl adenine (BA). Mature embryos were highest on both 0.5 and 1.0 mg/l 2,4-D (X = 15.8, 17.3), while shoot germination was enhanced by using BA in the regeneration media. The effect of high phosphorus concentration in the culture media was significant on both embryo induction and early maturation (X = 41). Lower ammonium nitrate concentrations enhanced growth and maturation of embryos. Both embryo maturation and the germination of shoots after 6 and 8 months of plating were best on low ammonium nitrate (X = 36.8 and 27.6 shoots, respectively). The presented embryogenic system will be of value for the clonal propagation, ex situ conservation and production of bioactive compounds from this threatened plant species.
MV Lyrae: Photometric study at high state

Photoelectric observations of novalike MV Lyr in a standard UBV system were carried out at Rozhen and Belogradchik observatories in 1992 and 1993. During all the nights of observations the star was in high state (V 12.5 mag). The observing runs performed in U and B bands show strong flickering activity and a typical shape of the red noise power spectrum. The periodogram anal- ysis of time series shows quasi-periodic oscillations with a period of about 50 min. The excitation of trapped oscilla- tions at the outer edge of the accretion disc, has been pro- posed as a possible mechanism for generation of MV Lyr quasi-periodic oscillations. The properties of the flickering in MV Lyr light curves were determined.
Efficient carbon ion beam generation from laser-driven volume acceleration

Experimental data on laser-driven carbon C6+ ion acceleration with a peak intensity of 5 × 1020 W cm−2 are presented and compared for opaque target normal sheath acceleration (TNSA) and relativistically transparent laser–plasma interactions. Particle numbers, peak ion energy and conversion efficiency have been investigated for target thicknesses from 50 nm to 25 μm using unprecedented full spectral beam profile line-out measurements made using a novel high-resolution ion wide-angle spectrometer. For thicknesses of about 200 nm, particle numbers and peak energy increase to 5 × 1011 carbon C6+ particles between 33 and 700 MeV (60 MeV u−1), which is a factor of five higher in particle number than that observed for targets with micron thickness. For 200 nm thick targets, we find that the peak conversion efficiency is 6% and that up to 55% of the target under the laser focal spot is accelerated to energies above 33 MeV. This contrasts with the results for targets with micron thickness, where surface acceleration with TNSA is dominant. The experimental findings are consistent with two-dimensional particle-in-cell simulations.
Stakeholders' Needs Assessments on Curriculum Development for Library and Information Science Program at Jimma University in Ethiopia: A Review

The review of stakeholders' needs assessments curriculum development for Library and Information Science program at Jimma University in Ethiopia was conducted. It established that the program passed through the fundamental principles of curriculum development that identified, considered and recognized the needs of stakeholders' in Ethiopia through needs assessments researches, whose outcomes informed the launching of the program. The review did not only highlight the need for the undergraduate program and its curriculum development to be all inclusive of courses offered, but also gave information on content, purpose, method, duration, trainers and locations of the program. It went further to point out how curriculum development for undergraduate professional degree program is centered on how the artifacts of human knowledge are structured, organized, managed, evaluated, and made accessible in libraries and information centers and why universities offering the program in Ethiopia believed that Information Science and newly emerging related fields like information systems and design must be taught together since the technical, humanistic, social, and behavioral aspects are interrelated. It finally observed how the library and information science curriculum should build into it the knowledge of technical possibilities and constraints, which shaped users services; as well as the redefinition of the traditional concept of library, which should be transformed from places to access paper records or books to one that also houses the most advanced electronic resources, including the Internet, digital collections and remote access to a wide range of information.
