Seasonal patterns of dietary partitioning in vertebrates
Creators: name: Porter, Cody
Publisher: name: Zenodo
Year: 2022

description: Dietary partitioning plays a central role in biological communities, yet the extent of partitioning often varies dramatically over time. Food availability may drive temporal variation in dietary partitioning, but alternative paradigms offer contrasting predictions about its effect. We compiled estimates of dietary overlap between co-occurring vertebrates to test whether partitioning is greater during periods of high or low food abundance. We found that dietary partitioning was generally greatest when food abundance was low, suggesting that competition for limited food drives partitioning. The extent of dietary partitioning in birds and mammals was also related to seasonality in primary productivity. As seasonality increased, partitioning increased during the nonbreeding season for birds and the breeding season for mammals. Although some hypotheses invoke changes in dietary breadth to explain temporal variation in dietary partitioning, we found no association between dietary breadth and partitioning. These results have important implications for the evolution of dietary divergence.

Creators: name: Shiferaw, Bemnet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: In the organization of services like hotel as the factors that can be important to improving quality of services, one is internal marketing. An Internal marketing activities in the development of an important organization is creating customer oriented employees. The main aim of internal marketing is having the knowledge of the internal and external customers and removing the obstacles in the way to value and quality of services. The purpose of this research is to investigate the effect of internal marketing on employee's customer orientation in star hotels which are found in Addis Ababa. The study is conducted with the objective of answering four basic questions i.e. to investigate the effect of motivation, empowerment, communication and training & development on customer orientation. In this research the researcher follows a deductive approach. This research is a descriptive and explanatory type of research. A quantitative method was used, whereby questionnaire was distributed to the employees of star hotels that are selected for the study. The effect of internal marketing on customer orientation was analyzed using bivariate correlation and standard multiple regression. This study used IBM SPSS software to conduct a bivariate correlation and standard multiple regression procedures to answer the basic research questions. The result indicates that all selected dimensions of internal marketing have positive and significant relation with customer orientation. Therefore, the hotels are recommended to consider implementing internal marketing principles to increase customer orientation of employees as it is one of the competitive advantages of an organization to remain competitive in such dynamic, ambiguous and turbulent business environment.

description: The Rashba physics has been intensively studied in the field of spin orbitronics, for the purpose of searching novel physical properties and the FM magnetization switching for technology applications. Here, we report the observation of the inverse Edelstein effect up to room temperature in the Rashba-split 2DEG between two insulating oxides SrTiO3 and LaAlO3 with the LaAlO3 layer thickness from 3 to 40 unit cells (UC). We further demonstrate that the spin voltage could be dramatically manipulated by electric field effect for the 2DEG between SrTiO3 and 3 UC LaAlO3. These results demonstrate that the Rashba-split 2DEG at the complex oxide interface can be used for room temperature efficient charge-and-spin conversion for the generation and detection of spin current.

description: The design of a prototype to carry out take-off and flight tests with tethered aircrafts is presented. The system features a ground station equipped with a winch and a linear motion system. The motion of these two components is regulated by an automatic control system, whose goal is to accelerate a tethered aircraft to take-off speed using the linear motion system, while reeling-out the tether from the winch with low pulling force and avoiding entanglement. The mechanical, electrical, measurement and control aspects of the prototype are described in detail. Experimental results with a manually-piloted aircraft are presented, showing a good matching with previous theoretical findings.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The purpose of this study is to investigate the pre and post implementation of change management (BSC and strategic planning) on performance of Ethiopian Federal Ministry of Health. Both qualitative and quantitative approaches are employed. The data are gathered from employees of the Ministry through survey questionnaires, and from directorate heads through interviews and focus group discussions. The researcher identified that the major bottleneck for implementation of strategic planning and BSC are lack of adequate resources for training and software, extent of staff participation and lack of adequate resources The research established that the balanced scorecard is a useful tool. It helps organizations to turn visions into reality with accuracy and efficiency. Strategy and BSC implementation therefore require that all business units, support units and employees be aligned and linked to the strategy and scorecard. The study concludes that the main objective of the Balanced ScoreCard is to bring the different perspectives (finance, internal business processes, learning, growth and clients) together in a uniform system. The study recommends organizations to adopt balanced scorecard and strategic planning for measuring performance and for better progress. But it should make deep investigation in implementing any management tools. Taking one or more countries as reference is not enough rather it is better to see or analyse the environment in which the organization is working. Finally the paper provides information and suggestions that are helpful for companies that are interested in developing strategic planning and balanced scorecard.

description: Understanding the phase behavior of mixtures with many components is important in many contexts, including as a key step toward a physics-based description of intracellular compartmentalization. Here, we study the instabilities of a mixture model where the second virial coefficients are taken as random Gaussian variables. Using tools from free probability theory we obtain the exact spinodal curve and the nature of instabilities for a mixture with an arbitrary composition, thus lifting the assumption of uniform mixture component densities pervading previous studies. We show that, by controlling the volume fraction of only a few components, one can systematically change the nature of the spinodal instability and achieve demixing for realistic scenarios by a strong {\em composition imbalance amplification}. This results from a non-trivial interplay of entropic effects due to non-uniform composition and complexity in the interactions. Our approach allows for the inclusion of any finite number of structured interactions, leading to a competition between different forms of demixing as density is varied.

description: The Mini-EUSO telescope is the first space-based detector of the JEM-EUSO program. It was launched for the International Space Station on August 22$^{nd}$, 2019 to observe from the ISS orbit ($\sim$420 km altitude) various phenomena occurring in the Earth's atmosphere through a UV-transparent window located in the Russian Zvezda Module. The dimension of the window defines and constrains the dimension of the optics, based on a set of two Fresnel lenses of 25 cm diameter each, almost two orders of magnitude smaller than the system foreseen for a larger space-based detector, like the original JEM-EUSO detector or the future POEMMA. As a consequence, the energy threshold of Mini-EUSO is very high, above $10^{21} $eV. Nevertheless, a series of events that resemble the shape and the time duration of EAS-induced events have been detected in Mini-EUSO data. This contribution presents the most interesting cases, showing that the vast majority of the EAS-like events can be traced back to ground sources repeatedly flashing and triggered many times by Mini-EUSO. Some non-repeated EAS-like events are also present. In these cases, it is possible to exclude their cosmic origin through the comparison with simulated events. Since it is clear that those events can not be originated by a UHECR, we decided to rename them "Short Light Transients" or SLTs. Finally, it was possible to associate some of the SLTs with atmospheric activity. This analysis confirms the validity of the JEM-EUSO detection principle and shows that it is possible for a space-based detector to distinguish between events induced by UHECRs and events with a different origin.

description: In this work, we show that a complex equiangular tight frame (ETF) composed by $N$ vectors in dimension $d$ exists if and only if a certain bistochastic matrix, univocally determined by $N$ and $d$, belongs to a special class of unistochastic matrices. This connection allows us to find new complex ETF in infinitely many dimensions and to derive a method to introduce non-trivial free parameters in ETF. We derive a 6-parametric family of complex ETF(6,16), which defines a family of symmetric POVM. Minimal and maximal possible average entanglement of the vectors within this qubit-qutrit family are presented. Furthermore, we propose an efficient numerical procedure to find the unitary matrix underlying a unistochastic matrix, which we apply to find all existing classes of complex ETF containing up to 19 vectors.

The equivalent action is nothing but the Einstein-Hilbert term in the bulk plus half of the Gibbons-Hawking term at the boundary. The derivation is based on the evaluation of the Noether charges in the vacuum. We obtain that the vacuum energy of this space has the same value as the one of the asymptotically flat limit of three-dimensional anti-de Sitter space.

description: We investigate the impact of stochastic quantum noise due to trans--Planckian effects on the primordial power spectrum for gravity waves during inflation. Given an energy scale Lambda, expected to be close to the Planck scale m_Pl and larger than the Hubble scale H, this noise is described in terms of a source term in the evolution equation for comoving modes k which changes its amplitude growth from early times as long as the mode physical wavelength is smaller than Lambda^-1. We model the source term as due to a gas of black holes in the trans--Planckian regime and the corresponding Hawking radiation. In fact, for energy scales larger than, or of the order of Lambda, it is expected that trapped surfaces may form due to large energy densities. At later times the evolution then follows the standard sourceless evolution. We find that this mechanism still leads to a scale-invariant power spectrum of tensor perturbations, with an amplitude that depends upon the ratio Lambda/m_Pl.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: This study examined the impact debt financing on manufacturing firms' financial performance evidenced from textile companies in Addis Ababa and Oromia Special Zone. The study employed explanatory research design with quantitative approach. To achieve the study objective secondary data were collected from the sample of 15 textile companies in Addis Ababa and Oromia Special Zone over the period of 2012-2016 using purposive sampling technique. The relationship between leverage which is measured by short term debt to total assets ratio (STDTA), long term debt to total assets ratio (LTDTA) and total debt to total assets ratio (TDTA) and financial performance measured by return on asset (ROA) and return on equity (ROE) were treated with descriptive statistics, correlation matrix and diagnostic tests. To analyze the cause-effect relationship between the explanatory variables and the dependent variables, fixed effect regression model was employed. Based on the fixed effect regression model output this study concluded that STDTA is negatively related with ROA and vice versa with ROE. LTDTA has positive relationship with financial performance measured by ROA & ROE. TDTA has negative impact on ROA but positively related with ROE. On the other hand, the control variables such as age (AG), asset turnover (ATO) and tangibility of assets (TOA) have significant and positive relationship with financial performance indicators, ROA & ROE whereas a control variable, i.e. firm size (FS) has significant and negative impact on financial performance measured by ROA & ROE.
Rosseland and flux mean opacities for Compton scattering

description: Rosseland mean opacity plays an important role in theories of stellar evolution and X-ray burst models. In the high-temperature regime, when most of the gas is completely ionized, the opacity is dominated by Compton scattering. Our aim here is to critically evaluate previous works on this subject and to compute exact Rosseland mean opacity for Compton scattering in a broad range of temperatures and electron degeneracy parameter. We use relativistic kinetic equations for Compton scattering and compute the photon mean free path as a function of photon energy by solving the corresponding integral equation in the diffusion limit. As a byproduct we also demonstrate the way to compute photon redistribution functions in case of degenerate electrons. We then compute the Rosseland mean opacity as a function of temperature and electron degeneracy. We compare our results to the previous calculations and find a significant difference in the low-temperature regime and strong degeneracy. We find useful analytical expressions that approximate well the numerical results. We then proceed to compute the flux mean opacity and show that in diffusion approximation it is nearly identical to the Rosseland mean opacity. We also provide a simple way for accounting for the true absorption in evaluation of the Rosseland and flux mean opacities.

description: To address the widespread impacts of climate change, nations are developing legal and policy adaptation mechanisms. Climate change impacts women more than men, particularly in developing nations, by exacerbating inequalities through a variety of social, economic, cultural and environmental barriers. Thus, gender-based approaches have been introduced to ensure climate justice for women. The Cancun Agreement, 2010 and the Lima Work Programme, 2014 on Gender stress the importance of the empowerment of women to ensure their meaningful participation in, and contribution to, climate decision-making and actions. In 2019, Bangladesh is the 9th most vulnerable nation in the world, in regard to the impacts of climate change. Women represent half the population of 163 million. The nation has recognized the importance of gender equity as one of its goals for Vision 2021.The Constitution of Bangladesh has safeguarded gender focused environmental rights without discrimination as fundamental rights However, these are rarely enforced and majority of women in Bangladesh do not enjoy equal gender rights. This study will draw upon international environment law to build the case for addressing this inequity. Among the 19 environmental laws, only the Bangladesh Environment Conservation Act, 1995 and the Environment Court Act, 2010, are applied and practiced routinely in the three environment courts, thus they are the legal instruments at the center of this research. However, due to some drawback provisions such as, “national interest” and “good faith”, these laws are not fully enforceable in the courts in the context of gender equity. This study will focus on these two environmental laws in responding to the overarching research question. As part of the investigation, this research will draw upon the legislation and its enforcement in nations such as, Kenya and Bhutan, which are recognized as best practice exemplars in gender equity and climate adaptation.

description: We prove that every Kakeya set in $\mathbb{R}^3$ formed from lines of the form $(a,b,0) + \operatorname{span}(c,d,1)$ with $ad-bc=1$ must have Hausdorff dimension $3$; Kakeya sets of this type are called $SL_2$ Kakeya sets. This result was also recently proved by Fässler and Orponen using different techniques. Our method combines induction on scales with a special structural property of $SL_2$ Kakeya sets, which says that locally such sets look like the pre-image of an arrangement of plane curves above a special type of map from $\mathbb{R}^3$ to $\mathbb{R}^2$, called a twisting projection. This reduces the study of $SL_2$ Kakeya sets to a Kakeya-type problem for plane curves; the latter is analyzed using a variant of Wolff's circular maximal function.

description: We present novel constraints on cosmic-ray propagation in the Galaxy using the recent precise measurements of proton and helium spectra from AMS-02, together with preliminary AMS-02 data on the antiproton over proton ratio. To explore efficiently the large (up to eleven-dimensional) parameter space we employ the nested-sampling algorithm as implemented in the \textsc{MultiNest} package, interfaced with the \textsc{Galprop} code to compute the model-predicted spectra. We use VOYAGER proton and helium data, sampling the local inter-stellar spectra, to constrain the solar modulation potential. We find that the turbulence of the Galactic magnetic field is well constrained, i.e., $δ=0.30^{+0.03}_{-0.02}(stat)^{+0.10}_{-0.04}(sys)$, with uncertainties dominated by systematic effects. Systematic uncertainties are determined checking the robustness of the results to the minimum rigidity cut used to fit the data (from 1 GV to 5 GV), to the propagation scenario (convection vs no-convection), and to the uncertainties in the knowledge of the antiproton production cross section. Convection and reaccelaration are found to be degenerate and not well-constrained singularly when using data above 5 GV. Using data above 1 GV reacceleration is required, $v_{\rm A}=25\pm2$km/s, although this value might be significantly affected by the low energy systematic uncertainty in the solar modulation. In a forthcoming companion paper, we investigate the constraints imposed by AMS-02 measurements on lithium, boron, and carbon.

description: Polymer Electrolyte Membrane Fuel Cells (PEMFCs) are a promising alternative to replace Internal Combustion (IC) engines due to their zero-tailpipe emission and fast refuelling time. However, prolonged durability requirements are still remaining challenges for PEMFCs technologies. In addition, not only the prolonged durability requirement itself, measuring the lifetime of a PEMFCs are highly time- and resource-consuming. The aim of this research is to develop Accelerated Test Cycles (ATC) based on real-world PEMFCs operations to predict the degradations of real-world operations in a much-reduced testing time.

description: Monte Carlo calculations of fermionic systems with continuous auxiliary fields frequently suffer from a diverging variance. If a system has the infinite variance problem, one cannot estimate observables reliably even with an infinite number of samples. In this paper, we explore a method to deal with this problem based on sampling according to the distribution of a system with an extra time-slice. The necessary reweighting factor is computed both perturbatively and through a secondary Monte Carlo. We show that the Monte Carlo reweigthing coupled to the use of a non-biased estimator of the reweigthing factor leads to a method that eliminates the infinite variance problem at a very small extra cost. We compute the double occupancy in the Hubbard model at half-filling to demonstrate the method and compare the results to well established results obtained by other methods.

description: We present a new technique to create a bin-averaged Hubble Diagram (HD) from photometrically identified SN~Ia data. The resulting HD is corrected for selection biases and contamination from core collapse (CC) SNe, and can be used to infer cosmological parameters. This method, called "BBC" (BEAMS with Bias Corrections), includes two fitting stages. The first BBC fitting stage uses a posterior distribution that includes multiple SN likelihoods, a Monte Carlo simulation to bias-correct the fitted SALT-II parameters, and CC probabilities determined from a machine learning technique. The BBC fit determines 1) a bin-averaged HD (average distance vs. redshift), and 2) the nuisance parameters alpha and beta, which multiply the stretch and color (respectively) to standardize the SN brightness. In the second stage, the bin-averaged HD is fit to a cosmological model where priors can be imposed. We perform high precision tests of the BBC method by simulating large (150,000 event) data samples corresponding to the Dark Energy Survey Supernova Program. Our tests include three models of intrinsic scatter, each with two different CC rates. In the BBC fit, the SALT-II nuisance parameters alpha and beta are recovered to within 1% of their true values. In the cosmology fit, we determine the dark energy equation of state parameter w using a fixed value of Omega_matter as a prior: averaging over all six tests based on 6 x 150,000 = 900,000 SNe, there is a small w-bias of 0.006 +- 0.002. Finally, the BBC fitting code is publicly available in the SNANA package.

description: We present Ego3DPose, a highly accurate binocular egocentric 3D pose reconstruction system. The binocular egocentric setup offers practicality and usefulness in various applications, however, it remains largely under-explored. It has been suffering from low pose estimation accuracy due to viewing distortion, severe self-occlusion, and limited field-of-view of the joints in egocentric 2D images. Here, we notice that two important 3D cues, stereo correspondences, and perspective, contained in the egocentric binocular input are neglected. Current methods heavily rely on 2D image features, implicitly learning 3D information, which introduces biases towards commonly observed motions and leads to low overall accuracy. We observe that they not only fail in challenging occlusion cases but also in estimating visible joint positions. To address these challenges, we propose two novel approaches. First, we design a two-path network architecture with a path that estimates pose per limb independently with its binocular heatmaps. Without full-body information provided, it alleviates bias toward trained full-body distribution. Second, we leverage the egocentric view of body limbs, which exhibits strong perspective variance (e.g., a significantly large-size hand when it is close to the camera). We propose a new perspective-aware representation using trigonometry, enabling the network to estimate the 3D orientation of limbs. Finally, we develop an end-to-end pose reconstruction network that synergizes both techniques. Our comprehensive evaluations demonstrate that Ego3DPose outperforms state-of-the-art models by a pose estimation error (i.e., MPJPE) reduction of 23.1% in the UnrealEgo dataset. Our qualitative results highlight the superiority of our approach across a range of scenarios and challenges.

description: We consider a population dynamics model coupling cell growth to a diffusion in the space of metabolic phenotypes as it can be obtained from realistic constraints-based modelling. In the asymptotic regime of slow diffusion, that coincides with the relevant experimental range, the resulting non-linear Fokker-Planck equation is solved for the steady state in the WKB approximation that maps it into the ground state of a quantum particle in an Airy potential plus a centrifugal term. We retrieve scaling laws for growth rate fluctuations and time response with respect to the distance from the maximum growth rate suggesting that suboptimal populations can have a faster response to perturbations.

description: A framework for studying the effect of the coupling to the heat bath in models exhibiting anomalous heat conduction is described. The framework is applied to the harmonic chain with momentum exchange model where the non-trivial temperature profile is calculated. In this approach one first uses the hydrodynamic (HD) equations to calculate the equilibrium current-current correlation function in large but finite chains, explicitly taking into account the BCs resulting from the coupling to the heat reservoirs. Making use of a linear response relation, the anomalous conductivity exponent $α$ and an integral equation for the temperature profile are obtained. The temperature profile is found to be singular at the boundaries with an exponent which varies continuously with the coupling to the heat reservoirs expressed by the BCs. In addition, the relation between the harmonic chain and a system of noninteracting L{é}vy walkers is made explicit, where different BCs of the chain correspond to different reflection coefficients of the L{é}vy particles.

This allows for a zoo of dynamical phenomena not possible for hyperbolic attractors. The purpose of this Letter is to demonstrate these phenomena in the border-collision normal form. This is a continuous, piecewise-linear family of maps that is physically relevant as it captures the dynamics created in border-collision bifurcations in diverse applications. Since the maps are piecewise-linear they are relatively amenable to an exact analysis and we are able to explicitly identify parameter values for heterodimensional cycles and blenders. For a one-parameter subfamily we identify bifurcations involved in a transition through unstable dimension variability. This is facilitated by being able to compute periodic solutions quickly and accurately, and the piecewise-linear form should provide a useful test-bed for further study.

description: أصبحت المسؤولية الاجتماعية للجامعة بشكل متزايد في صميم الجدل حول دور الجامعة في تعزيز البعد الاجتماعي، حيث تهدف هذه الدراسة إلى توضيح دور المسؤولية الاجتماعية للجامعات في تعزيز البعد الاجتماعي للتعليم العالي في الجزائر. و محاولة الإجابة على السؤال التالي: ما هي الوسائل التي يمكن من خلالها دمج مفهوم المسؤولية الاجتماعية في الجامعات الجزائرية من أجل تعزيز بعدها الاجتماعي؟ وتوصلت الدراسة إلى أن دمج المسؤولية الاجتماعية في الجامعات الجزائرية جد ضعيف ويحتاج المزيد من الجهود من أجل تعزيز دورها في المجتمع نظرا للفائدة التي تحققها الجامعة من محيطها من جهة وكذا استفادة المجتمع من تواجدها فيه من جهة أخري، وهنا نكون أمام علاقة تبادلية قوية تحتم التعامل المشترك بين الجامعة والمجتمع، وهذا حسب نتائج الدراسة التي تمت وفق المنهج الوصفي التحليلي من خلال قراءة معمقة حول الأدبيات النظرية للموضوع، والجانب التطبيقي الذي تم فيه تقديم استبيان الكتروني لعدد من الأساتذة الجامعين الجزائريين، باستخدام (Google Drive) و (facebook)، وأوصت الدراسة في الأخير إلى أنه يجب أن يتم اليوم دمج المسؤولية الاجتماعية في إستراتيجية الجامعات للمساهمة في تحسين رفاهية المجتمع والتنمية المستدامة، وذلك من خلال تنفيذ إستراتيجية عالمية تقوم على الدراسات والبحوث التي تتعلق بجميع القطاعات الاقتصادية والفئات الاجتماعية. الكلمات المفتاحية: المسؤولية الاجتماعية، البعد الاجتماعي، التعليم العالي، الجامعات. The social responsibility of the university is increasingly at the heart of the debate about the role of the university in promoting the social dimension. This study aims at clarifying the role of social responsibility of universities in promoting the social dimension of higher education in Algeria. And to try to answer the following question: What are the means by which the concept of social responsibility can be integrated into Algerian universities in order to enhance their social dimension? The study concluded that the integration of social responsibility in the Algerian universities is very weak and needs more efforts to enhance its role in society because of the benefit achieved by the university from its surroundings on the one hand and the benefit of society from its presence on the other hand, and here we are facing a strong reciprocal relationship, Between the university and the society. This is according to the results of the study which was carried out according to the analytical descriptive method through an in-depth reading on the theoretical literature of the subject and the practical aspect in which an electronic questionnaire was submitted to a number of Algerian university professors using Google Drive and Facebook. In the latter that must be today the integration of social responsibility in the university's strategy to contribute to improving the well-being of society and sustainable development, through the implementation of a global strategy based on research and studies relating to all economic sectors and social groups. Key words: social responsibility, social dimension, higher education, universities. JEL Code: M14.

description: We study strong field molecular ionization using few- (four to ten) cycle laser pulses. Employing a supercontinuum light source, we are able to tune the optical laser wavelength (photon energy) over a range of about $\sim$200 nm (500 meV). We measure the photoelectron spectrum for a series of different molecules as a function of laser intensity, frequency, and bandwidth and illustrate how the ionization dynamics vary with these parameters. We find that multiphoton resonances and nonadiabatic dynamics (internal conversion) play an important role and result in ionization to different ionic continua. Interestingly, while nuclear dynamics can be "frozen" for sufficiently short laser pulses, we find that resonances strongly influence the photoelectron spectrum and final cationic state of the molecule regardless of pulse duration -- even for pulses that are less than four cycles in duration.

description: The purpose of this study was to examine factors that influence the distribution performance of Muger cement factory. The guiding research question of this study was `` To what extent dose financial capacity, transport outsourcing and information system impact the distribution performance of Muger cement factory. The study used a stratified method of sampling technique on sample respondents Muger cement management staffs comprising of 2-top management, 9-process owners and 82-team leaders: who are located at Muger, Tatek and Addis Ababa cement. A structured questionnaire was developed by the researcher and a quantitative data was gathered and used. From the distributed 93-questionaire, 78 of them are responded which constitute more than 80 percent of response rate. A correlation and regression analysis as well as an explanatory approach was employed to explain the extent of relationship between variables of interest. Further, statistical methods such as, descriptive statistics (like mean), Statistical Package for Social Scientist (SPSS) version 20 was also used to analyze the data. Additional, tables and charts were used to present the study results. The finding indicates that; financial capacity, transport outsourcing and information system had a significant positive impact on the distribution performance of the factory. It also indicates that; financial capacity and information system followed by transport outsourcing have the greatest influence on distribution performance respectively. The finding of the study implies that financial capacity, transport outsourcing and information system must be given due attention if the factory wants to enhance its distribution performance. Based on the result obtained in the analysis and conclusion made; the researcher recommend that the factory need to have an efficient payment system with liquidity in place together with training of employees with respect to proper planning and management of outsourcing and implementation of an information technology like ERP and GIS to ensure its distribution competitiveness in the industry

description: The inefficiency of star formation in massive elliptical galaxies is widely believed to be caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas. Achieving a sufficiently rapid reddening of moderately massive galaxies without expelling too many baryons has however proven difficult for hydrodynamical simulations of galaxy formation, prompting us to explore a new model for the accretion and feedback effects of supermassive black holes. For high accretion rates relative to the Eddington limit, we assume that a fraction of the accreted rest mass energy heats the surrounding gas thermally, similar to the `quasar mode' in previous work. For low accretion rates, we invoke a new, pure kinetic feedback model which imparts momentum into the surrounding gas in a stochastic manner. These two modes of feedback are motivated both by theoretical conjectures for the existence of different types of accretion flows as well as recent observational evidence for the importance of kinetic AGN winds in quenching galaxies. We find that a large fraction of the injected kinetic energy in this mode thermalises via shocks in the surrounding gas, thereby providing a distributed heating channel. In cosmological simulations, the resulting model produces red, non star-forming massive elliptical galaxies, and achieves realistic gas fractions, black hole growth histories and thermodynamic profiles in large haloes.

description: We present a continuation of an analysis that aims to quantify resolution of $N$-body simulations by exploiting large (up to $N=4096^3$) simulations of scale-free cosmologies run using Abacus. Here we focus on radial pairwise velocities of the matter field, both by direct estimation and through the cumulative-2PCF (using the pair conservation equation). We find that convergence at the $1\%$ level of the mean relative pairwise velocity can be demonstrated over a range of scales, evolving from a few times the grid spacing at early times to slightly below this scale at late times. We show the analysis of two different box sizes as well as from averaging results from the smaller boxes, and compare the power of the two aforementioned estimators in constraining accuracy at each scale. Down to scales of order of the smoothing parameter, convergence is obtained at $\sim5\%$ precision, and shows a behaviour indicating asymptotic stable clustering. We also infer for LCDM simulations conservative estimates on the evolution of the lower cut-off to resolution (at $1\%$ and $5\%$ precision) as a function of redshift.
