description: In this work, we present an experimental study based on the combined transfer of heat and mass in a porous medium made of baked clay, in which measurements of the physical parameters (temperature, relative humidity, wind speed, quantity of water) were taken for 30 days. This article explores the design, construction and testing of an innovative water cooling system based on evaporation, using porous jars and a layer of sand. The results obtained show that climatic and physical factors have a major impact on cooling. The aim is to analyse the effectiveness of this system, both in terms of reducing the water temperature and preserving it in hot climatic conditions. The lowest water temperature value (minimum) of 16.32°C was observed during the last three days of December, when the relative air humidity had fallen to 45% with an ambient temperature of 27.55°C; during this period the wind speed was 20 km/h. The maximum temperature of the water in the jar, 25.51°C, was observed on 16 January with a relative air humidity of 81%, an ambient temperature of 27.55°C and a low wind speed of 10km/h. We therefore understand that the climatic and physical factors mentioned above have an influence on the phenomenon of water cooling from the fired clay jar.

Socio-Economic Determinants of Fertility in Urban Ethiopia
Creators: name: Tadesse, Fanaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: Fertility, being a major study unit in population dynamics, should be analyzed from different perspectives as it plays a pivotal role in understanding the complex issues integral to population growth. The main objective of this study was therefore to understand what the micro level major socio – economic determinants of fertility are in the case of urban Ethiopia. These determinants of fertility were initially hypothesized to include education, income, age at first marriage, marital status, child mortality and participation of women in income generating activities. The direction of relationship between the variables and fertility was expected to be positive for martial status and child mortality while a negative relationship was speculated for the other variables. Count data models were used to estimate fertility, given by the number of children born by a woman, using two data sets: the Ethiopian Urban Socio-economic Surveys, a panel data conducted for five rounds comprising of 1,500 households, and the Ethiopian Demographic and Health Survey (2005), a nationally representative cross sectional data. The main findings of the result supported the hypothesis that education, income, age at first marriage and participation of women in income generating activity are negatively related to fertility. The expected positive relationship between marriage and fertility was also validated by the study. Child mortality was, however, found to be insignificant in explaining fertility in urban areas. The findings of the study revealed that fertility decision is influenced by the analyzed socio-economic variables and achieving a low level of fertility rate requires an all rounded sustainable development process that could result in increased education, income, creation of employment opportunities and improved status of women in the society

description: We investigate a generalized Aubry-André-Harper (AAH) model with p-wave superconducting pairing. Both the hopping amplitudes between the nearest neighboring lattice sites and the on-site potentials in this system are modulated by a cosine function with a periodicity of $1/α$. In the incommensurate case [$α=(\sqrt{5}-1)/2$], due to the modulations on the hopping amplitudes, the critical region of this quasiperiodic system is significantly reduced and the system becomes more easily to be turned from extended states to localized states. In the commensurate case ($α= 1/2$), we find that this model shows three different phases when we tune the system parameters: Su-Schrieffer-Heeger (SSH)-like trivial, SSH-like topological, and Kitaev-like topological phases. The phase diagrams and the topological quantum numbers for these phases are presented in this work. This generalized AAH model combined with superconducting pairing provides us with a useful testfield for studying the phase transitions from extended states to Anderson localized states and the transitions between different topological phases.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: Recognizing the benefits of Information Communication Technologies (ICTs) in general and Internet in particular to the overall advancement of social, economic and politics of a country, developing countries are investing on network infrastructures. However, the penetration level of the countries such as Ethiopia has been very low which will hinder the country not to reap the benefits of the technologies. The purpose of this study was to identify the determinants of Internet diffusion among business organization in Addis Ababa. Hence, a survey was conducted on a random sample of businesses and a logit model of Internet access was estimated. The major result of the estimated model indicate that the likelihood of access to the Internet by a firm is explained by the level of the education of the management, level of sales of the business and its openness to international trade. Furthermore, the descriptive analysis showed that among the connected businesses the use of Internet is limited to email and browsing, while advanced electronics uses such as E-commerce, E-procurement, etc. are almost non-existent

description: This paper looks into the analysis of the long-range auto-correlations and cross-correlations in bond market. Based on Detrended Moving Average (DMA) method, empirical results present a clear evidence of long-range persistence that exists in one year scale. The degree of long-range correlation related to maturities has an upward tendency with a peak in short term. These findings confirm the expectations of fractal market hypothesis (FMH). Furthermore, we have developed a method based on a complex network to study the long-range cross-correlation structure and apply it to our data, and found a clear pattern of market segmentation in the long run. We also detected the nature of long-range correlation in the sub-period 2007 to 2012 and 2011 to 2016. The result from our research shows that long-range auto-correlations are decreasing in the recent years while long-range cross-correlations are strengthening.

Subjects: massive binaries, young open clusters, multiple populations

description: Young star clusters are exceptional laboratories for advancing our understanding of stellar evolution. With the majority of massive stars being born in binary systems, where their properties can be altered significantly through interactions, multiple stellar components in young star clusters that cannot be characterized by one simple isochrone should be expected. Recent high-quality observations using the Hubble Space Telescope have indeed revealed the presence of multiple stellar components within young Magellanic Cloud star clusters. In this talk, I will discuss the success and limitations of the current binary evolution theory in interpreting the observed multiple stellar components in young star clusters. By doing so, we provide useful constraints on stellar formation and evolution theory.

A numerical and experimental comparison of a fully-passive oscillating-foil turbine operating in different confinement levels is conducted to assert how well CFD-based FSI simulations can predict the performances of the turbine. It is found the present 3D URANS simulations match reasonably well the experimental observations, especially in terms of pitch angles and power extraction. Indeed, the results confirm that confinement increases the extracted power and the efficiency of the fully-passive blade. At low confinement level, the main flow features are shown to be well captured by the simulations. At large confinement levels, some issues with lateral walls interactions are discussed as possible explanation for the observed discrepancies.

description: The ability to encode and embed desired mechanical properties into active pharmaceutical ingredient solid forms would significantly advance drug development. In recent years, computational methods, particularly dispersion-corrected density functional theory (DFT), have come of age, opening the possibility of reliably predicting and rationally engineering the mechanical response of molecular crystals. Here, many-body dispersion and Tkatchenko−Scheffler dispersion-corrected DFT were used to calculate the elastic constants of a series of archetypal systems, including paracetamol and aspirin polymorphs and model hydro-gen-bonded urea and π−π-bound benzene crystals, establishing their structure−mechanics relations. Both methods showed semiquantitative and excellent qualitative agreement with experiment. The calculations revealed that the plane of maximal Young’s modulus generally coincides with extended H-bond or π−π networks, showing how programmable supramolecular packing dictates the mechanical behavior. In a pharmaceutical setting, these structure−mechanics relations can steer the molecular design of solid forms with improved physicochemical and compression properties

description: Using the Sloan Digital Sky Survey, we adopt the sSFR-$Σ_{1kpc}$ diagram as a diagnostic tool to understand quenching in different environments. sSFR is the specific star formation rate, and $Σ_{1kpc}$ is the stellar surface density in the inner kpc. Although both the host halo mass and group-centric distance affect the satellite population, we find that these can be characterised by a single number, the quenched fraction, such that key features of the sSFR-$Σ_{1kpc}$ diagram vary smoothly with this proxy for the "environment". Particularly, the sSFR of star-forming galaxies decreases smoothly with this quenched fraction, the sSFR of satellites being 0.1 dex lower than in the field. Furthermore, $Σ_{1kpc}$ of the transition galaxies (i.e., the "green valley" or GV) decreases smoothly with the environment, by as much as 0.2 dex for $M_* = 10^{9.75-10} M_{\odot}$ from the field, and decreasing for satellites in larger halos and at smaller radial distances within same-mass halos. We interpret this shift as indicating the relative importance of today's field quenching track vs. the cluster quenching track. These environmental effects in the sSFR-$Σ_{1kpc}$ diagram are most significant in our lowest mass range ($9.75 < \log M_{*}/M_{\odot} < 10$). One feature that is shared between all environments is that at a given $M_{*}$ quenched galaxies have about 0.2-0.3 dex higher $Σ_{1kpc}$ than the star-forming population. These results indicate that either $Σ_{1kpc}$ increases (subsequent to satellite quenching), or $Σ_{1kpc}$ for individual galaxies remains unchanged, but the original $M_*$ or the time of quenching is significantly different from those now in the GV.

description: High-bunch-charge photoemission electron-sources operating in a continuous wave (CW) mode are required for many advanced applications of particle accelerators, such as electron coolers for hadron beams, electron-ion colliders, and free-electron lasers (FELs). Superconducting RF (SRF) has several advantages over other electron-gun technologies in CW mode as it offers higher acceleration rate and potentially can generate higher bunch charges and average beam currents. A 112 MHz SRF electron photoinjector (gun) was developed at Brookhaven National Laboratory (BNL) to produce high-brightness and high-bunch-charge bunches for the Coherent electron Cooling Proof-of-Principle (CeC PoP) experiment. The gun utilizes a quarter-wave resonator (QWR) geometry for assuring beam dynamics, and uses high quantum efficiency (QE) multi-alkali photocathodes for generating electrons.

description: Videonystagmoscopy visualizes nystagmus on a television monitor and records it on video tape for later study, records, and reproduction. Early attempts date from long ago, but the technique only recently has spread, since the development of complex computerized equipment which, however, confines it to certain vestibular exploration laboratories. In order for this technique to become more widely used, simple equipment is needed, such as that described in this article. Our system consists of a single infrared light minivideo camera that is attached to the left eye using an eyeglass-mounting system that also occludes the right eye. The examination method is routine. Our results show the following advantages over electronystagmography: visualization of the rotary component, non-interference of visual stimuli, mechanical and electronic stability, speed, and low cost. If necessary, it can be complemented by electronystagmography and computer analysis.
The Impact of Micro-financing on Poverty Reduction: A Case Study of Oromiya Credit & Saving Share Company (Ocssco) In Eastern Wollega Zone of Oromiya National Regional State, Ethiopia
Creators: name: Moti, Daba

description: The prevalence of poverty has been a common phenomenon in Ethiopia. The prevailing operation of the conventional financial institutions in Ethiopia is inefficient in providing financial services to the poor. The challenge Ethiopia is facing today is to reduce poverty and achieve sustained economic growth for healthy national development. One of the economic policies of the country is introduction of MFIs in the country. Currently, microfinancing is being practiced in the country as a tool to deliver financial services to the poor with the objective of attacking poverty. OCSSCO, one of the 22 licensed microfinance institutions in Ethiopia, was established in August 1997 in ORNS for this purpose. The objective of this study, therefore, is to find out whether the delivery of financial services of the MFI has made changes on living standard of the clients. Primary data were collected through structured questionnaire from clients and non-clients using simple random sampling method. Secondary data were gathered from different MFIs' reports and literatures. Both are quantitative and qualitative in nature. Descriptive analysis, dichotomous binary model and sensitivity analysis were applied in the study. The impacts are analyzed based on two approaches. First, the impacts are observed in association mainly with income, which in turn have effects on nutritional status, access to education and medical facilities, employment generation, savings and empowerment, among others. The finding indicates that the OCSSCO's microfinancing scheme has made positive contribution to the clients in relation with observed variables. The impacts are also evaluated based on MFI's outreach and sustainability having the conceptual framework that if both outreach and sustainability have been enhanced then the program intervention is judged to have a positive impact as it has created the financial market to the poor. The finding also indicates that in spite of improvement in outreach and sustainability, a number of respondents are looking for the services. However, considering the sustainability of the MFI, the result shows 100% loan repayment performance except the first year of establishment in the study area. Adequate advising, supervision and giving services on time are some of the factors that help in loan repayment performance. The overall objective of MFIs in Ethiopia is to increase the productive potential of the poor and poverty reduction. The study found out the importance of the program. The intervention has enabled the clients to generate income that could be spent on better facilities, which could improve the living standard of clients. Therefore, strengthening the existing operation would be appropriate socio-economic policy. KEY WORDS: Microfinance, Loan products, saving products, Impact assessement, Outreach, Sustainability, Poverty.

description: Frenzel lenses is an important tool in vestibular pathology evaluation. It contains lenses that magnify patients eyes but deny the patient of visual fixation so as not to suppress nystagmus. Complete suppression of visual fixation, enhanced imaging, and recordability of images can be achieved with Video Frenzel Goggles. Commercially available video-eye movement recording systems/video frenzel goggles are very expensive and not readily available. A low cost video frenzel goggles was made out of locally available materials. The video system was provided by a detachable web camera which can be connected to any Personal Computer to produce the image. The Low Cost Video Frenzel Goggles (LCVFG) proposed in this study was comparable to the commercially available video frenzel system in terms of function, weight, comfort and ease of execution of the vestibular tests.

description: Chiral phase transition for three-flavor $N_f=2+1$ QCD with $m_u=m_d\neq m_s$ is investigated in a modified soft-wall holographic QCD model. Solving temperature dependent chiral condensates from equations of motion of the modified soft-wall model, we extract the quark mass dependence of the order of chiral phase transition in the case of $N_f=2+1$, and the result is in agreement with the "Colombia Plot", which is summarized from lattice simulations and other non-perturbative methods. First order phase transition is observed around the three flavor chiral limit $m_{u/d}=0, m_{s}=0$, while at sufficient large quark masses it turns to be a crossover phase transition. The first order and crossover regions are separated by a second order phase transition line. The second order line is divided into two parts by the $m_{u/d}=m_s$ line, and the $m_s$ dependence of the transition temperature in these two parts are totally contrast, which might indicate that the two parts are governed by different universality classes.

The Determinants of Agricultural Productivity and Rural Household income in Ethiopia
Creators: name: Urgessa, Tessema
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This paper aims at investigating the determinants of agricultural productivity and rural household income in Ethiopia. Three econometric modes namly: Pooled ordinary least square (POLS), fixed effects (FE) and random effects (RE) model were used to examine the relationship between productivity and income; using Ethiopian socio-economic survey of 2011/12 and 2013/14 data, collected by CSA of Ethiopia in collaboration with the world bank. Results showed that, Land-labor ratio, use of pesticide, manure and household size are found to be the most significant variables that affect agricultural labor and land productivity. However, drought has statistically significant and has negative effect on both labor and land productivity by the same magnitude. Labor productivity, non-farm income and land productivity are found to be the most determinants of household income. However, number of dependency ratio is significantly and negatively affects the rural household income. Sex of the household head is the main socio-economic factor for the variation of income among the rural households. The study also concludes that, Labor productivity is the most potent for factor of production and rural household income enhancement. The policy implication of the study is that, increasing landlabor ratio is important for agricultural productivity enhancement and promotion of both farm labor and non-farm income are best focusing to speed up for the enhancement of rural household income. Key words: Labor productivity, Land productivity; Rural Household income, Rural Household Panel Data, Fixed effect model.

description: Dissipative solitons are self-localized structures resulting from a double balance between dispersion and nonlinearity as well as dissipation and a driving force. They occur in a wide variety of fields ranging from optics, hydrodynamics to chemistry and biology. Recently, significant interest has focused on their temporal realization in driven optical microresonators, known as dissipative Kerr solitons. They provide access to coherent, chip-scale optical frequency combs, which have already been employed in optical metrology, data communication and spectroscopy. Such Kerr resonator systems can exhibit numerous localized intracavity patterns and provide rich insights into nonlinear dynamics. A particular class of solutions consists of breathing dissipative solitons, representing pulses with oscillating amplitude and duration, for which no comprehensive understanding has been presented to date. Here, we observe and study single and multiple breathing dissipative solitons in two different microresonator platforms: crystalline $\mathrm{MgF_2}$ resonator and $\mathrm{Si_3N_4}$ integrated microring. We report a deterministic route to access the breathing state, which allowed for a detailed exploration of the breathing dynamics. In particular, we establish the link between the breathing frequency and two system control parameters - effective pump laser detuning and pump power. Using a fast detection, we present a direct observation of the spatiotemporal dynamics of individual solitons, revealing irregular oscillations and switching. An understanding of breathing solitons is not only of fundamental interest concerning nonlinear systems close to critical transition, but also relevant for applications to prevent breather-induced instabilities in soliton-based frequency combs.

description: In vitro reconstituted active systems, such as the ATP-driven microtubule bundle suspension developed by the Dogic group, provide a fertile testing ground for elucidating the phenomenology of active liquid crystalline states. Controlling such novel phases of matter crucially depends on our knowledge of their material and physical properties. In this letter, we show that the rheological properties of an active nematic film can be probed by varying its hydrodynamic coupling to a bounding oil layer. Using the motion of disclinations as intrinsic tracers of the flow field and a hydrodynamic model, we obtain an estimate for the as of now unknown shear viscosity of the nematic film. Knowing this now provides us with an additional handle for robust and precision tunable control of the emergent dynamics of active fluids.

In particular, we show how the number of solutions is affected by the nodal behavior of the weight function $a$. The proof is based on a careful shooting-type argument for the equivalent singular ODE problem. As a further application of this technique, the existence of multiple positive radial homoclinic solutions to $$ Δu + \bigl(a^+(\vert x \vert) - μa^-(\vert x \vert)\bigr) g(u) = 0, \qquad x \in \mathbb{R}^N, $$ is also considered.

description: Quantum interference of two independent particles in pure quantum states is fully described by the particles' distinguishability: the closer the particles are to being identical, the higher the degree of quantum interference. When more than two particles are involved, the situation becomes more complex and interference capability extends beyond pairwise distinguishability, taking on a surprisingly rich character. Here, we study many-particle interference using three photons. We show that the distinguishability between pairs of photons is not sufficient to fully describe the photons' behaviour in a scattering process, but that a collective phase, the triad phase, plays a role. We are able to explore the full parameter space of three-photon interference by generating heralded single photons and interfering them in a fibre tritter. Using multiple degrees of freedom - temporal delays and polarisation - we isolate three-photon interference from two-photon interference. Our experiment disproves the view that pairwise two-photon distinguishability uniquely determines the degree of non-classical many-particle interference.

The main result shows that foreign aid has a significant and positive effect on economic growth in the long run as well as in the short run. However, aid has insignificant and negative effect on savings in the long run while it has significantly negative influence in the short run. Further, the findings revealed a unidirectional causality running from economic growth to savings and foreign aid. It shows that unidirectional causality run from economic growth to savings; and also, there is two ways (feedback), granger causality between foreign aid and saving, which implies policies designed to stimulate domestic saving also facilitates foreign aid. To maintain and accelerate growth, should formulate policies to intensify the allocation of foreign resources into investment projects.

description: Claude Francis Milliet Dechales described the Coriolis effect in his 1674 Cursus seu Mundus Mathematicus. Dechales discussed and illustrated the deflection of both falling bodies and of projectiles launched toward the poles that should occur on a rotating Earth. Interestingly, this was done as an argument against the Earth's rotation, the deflections not having been observed at the time. Dechales's work follows on that of Giovanni Battista Riccioli, who had also described the effect in his Almagestum Novum of 1651.

description: In view of many European countries and the USA leading to the second wave of COVID-19 pandemic, winter season, the evolution of new mutations in the spike protein, and no registered drugs and vaccines for COVID-19 treatment, the discovery of effective and novel therapeutic agents is urgently required. The degrees and frequencies of COVID-19 clinical complications are related to uncontrolled immune responses, secondary bacterial infections, diabetes, cardiovascular disease, hypertension, and chronic pulmonary diseases. It is essential to recognize that the drug repurposing strategy so far remains the only means to manage the disease burden of COVID-19. Despite some success of using single-target drugs in treating the disease, it is beyond suspicion that the virus will acquire drug resistance by acquiring mutations in the drug target. The possible synergistic inhibition of drug efficacy due to drug-drug interaction cannot be avoided while treating COVID-19 and allied clinical complications. Hence, to avoid the unintended development drug resistance and loss of efficacy due to drug-drug interaction, multi-target drugs can be promising tools for the most challenging disease. In the present work, we have carried out molecular docking studies of compounds from the FDA approved drug library, and the FDA approved and passed phase −1 drug libraries with ten therapeutic targets of COVID-19. Results showed that known drugs, including nine anti-inflammatory compounds, four antibiotics, six antidiabetic compounds, and one cardioprotective compound, could effectively inhibit multiple therapeutic targets of COVID-19. Further in-vitro, in vivo, and clinical studies will guide these drugs' proper allocation to treat COVID-19. Communicated by Ramaswamy H. Sarma
Effects of Tariff Reduction and Tax Replacements on Growth, Poverty And Income Distribution in Ethiopia: A CGE-Microsimulation Analysis
Creators: name: Kebede, Alekaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This study utilizes a 15-sector static CGE model of International Food Policy Research Institute for Ethiopian economy. The study also used the Distributive Analysis (DAD) software to compute poverty and inequality indicators. Increasing domestic tax rates (that is, replacing the tariff revenue lost with either direct tax or indirect tax) increased exports of most agricultural commodities and industrial imports causing the domestic industries to contract in production and employment. Effects on GDP, consumer's welfare, factor rewards, poverty and income distribution are mixed. Replacing tariff by direct tax improved all these variables marginally by increasing changes in factor rewards and decreasing the price level (CPI). On the other hand, replacing tariff by indirect tax has worsening effect by deteriorating the changes in factor rewards and increasing the relative prices (CPI).

description: The two currently largest all-sky photometric datasets, WISE and SuperCOSMOS, were cross-matched by Bilicki et al. (2016) (B16) to construct a novel photometric redshift catalogue on 70% of the sky. Galaxies were therein separated from stars and quasars through colour cuts, which may leave imperfections because of mixing different source types which overlap in colour space. The aim of the present work is to identify galaxies in the WISExSuperCOSMOS catalogue through an alternative approach of machine learning. This allows us to define more complex separations in the multi-colour space than possible with simple colour cuts, and should provide more reliable source classification. For the automatised classification we use the support vector machines learning algorithm, employing SDSS spectroscopic sources cross-matched with WISExSuperCOSMOS as the training and verification set. We perform a number of tests to examine the behaviour of the classifier (completeness, purity and accuracy) as a function of source apparent magnitude and Galactic latitude. We then apply the classifier to the full-sky data and analyse the resulting catalogue of candidate galaxies. We also compare thus produced dataset with the one presented in B16. The tests indicate very high accuracy, completeness and purity (>95%) of the classifier at the bright end, deteriorating for the faintest sources, but still retaining acceptable levels of 85%. No significant variation of classification quality with Galactic latitude is observed. Application of the classifier to all-sky WISExSuperCOSMOS data gives 15 million galaxies after masking problematic areas. The resulting sample is purer than the one in B16, at a price of lower completeness over the sky. The automatic classification gives a successful alternative approach to defining a reliable galaxy sample as compared to colour cuts.

Bilateral Trade Between Ethiopia and Sudan: Does FTA Make Them Better?

description: This paper has tried to evaluate the determinants of bilateral trade flows particularly the effect of the Free Trade Agreement (FTA) between Ethiopia and Sudan during the years 2002 to 2011. Based on Panel data, Static and Dynamic Gravity models are applied to assess the determinants of basic and export trade flows including FTA, GDP, population, exchange rate and distance. Estimation results of the static model indicates that Economic size, FTA, distance are the basic factors affecting trade flows. Whereas the dynamic model shows the existence of strong correlation between the Ethiopian contemporary trades (export) flows and those of the previous year. Therefore, we see that the dynamic model fits the data better than the static one

description: The global prevalence of COVID-19 disease and the overwhelming increase in death toll urge scientists to discover new effective drugs. Although the drug discovery process is a challenging and time-consuming, fortunately, the plant kingdom was found to have many active therapeutics possessing broad-spectrum antiviral activity including those candidates active against severe acute respiratory syndrome coronaviruses (SARS-CoV). Herein, nine traditional Chinese medicinal plant constituents from different origins (Glycyrrhizin 1, Lycorine 2, Puerarin 3, Daidzein 4, Daidzin 5, Salvianolic acid B 6, Dihydrotanshinone I 7, Tanshinone I 8, Tanshinone IIa 9) previously reported to exhibit antiviral activity against SARS-CoV were virtually screened in silico (molecular docking) as potential inhibitors of SARS-CoV-2 target proteins. The tested medicinal plant compounds were in silico screened for their activity against two key SARS-CoV-2 target proteins; 3CLpro, and Spike binding-domain proteins. Among the tested medicinal plant compounds, Salvianolic acid B 6 (Sal-B) showed promising binding affinities against the two specified SARS-CoV-2 target proteins compared to the reference standards used. Hence molecular dynamics simulations followed by calculating the free-binding energy were carried out for Sal-B providing information on its affinity, stability, and thermodynamic behavior within the two SARS-CoV-2 target proteins as well as key ligand-protein binding aspects. Besides, the quantum mechanical calculations showed that Sal-B can adopt different conformations due to the existence of various rotatable bonds. Therefore, the enhanced antiviral activity of Sal-B among other studied compounds can be also attributed to the structural flexibility of Sal-B. Our study gives an explanation of the structure activity relationship required for targeting SARS-CoV-2 3CLpro and Spike proteins and also facilitates the future design and synthesis of new potential drugs exhibiting better affinity and specificity. Besides, an ADME study was carried out on screened compounds and reference controls revealing their pharmacokinetics properties. Communicated by Ramaswamy H. Sarma
