description: A obra Cenas de África? Romance Íntimo, de Pedro Félix Machado, é uma história de amor localizada nos cenários da Angola e da metrópole oitocentistas. O seu retrato da sociedade luandense inclui personagens femininas que reflectem vivências de mulheres que então habitavam a cidade. Sendo figuras burguesas, este estudo tenta perceber se tais personagens se identificam com o modelo social prescrito para as mulheres pelos valores burgueses oitocentistas. Tidas as suas capacidades por inferiores às dos homens, afirmava-se que eram especialmente dotadas para a gestão doméstica. Conclui-se que as personagens femininas aderem no geral a esse figurino.

Optimization of Parameters and Production of Bioethanol From Raw Coffee Wet Processing Waste
Creators: name: G/Mariam, Asrat
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: A large amount of coffee waste water is generated from coffee processing plants. These residues possess serious environmental problems following the direct discharge in to the nearby water bodies and cause serious environmental and health problems. This study aimed to: (i) review wet coffee processing waste management practice in Ethiopia, (ii) characterize wet coffee processing waste and determine its total reducing sugar potential, (iii) quantify wet coffee processing waste and estimate its bio-ethanol potential and also evaluate the feasibility of bio-ethanol production and (iv) optimize the parameters and produce bio ethanol from wet coffee processing waste. The review of wet coffee processing waste management practice in Ethiopia revealed that there are about 1026 operational wet coffee processing industries and many more industries are under construction. In 2012, the estimated amount of wet coffee processing waste from operational industries in Ethiopia was about 291,600 tones / year. The study also examined the characteristics of wet coffee waste. The volatile solid of the Pulp juice and Mucilage were determined and showed that the wastes have high organic component, i.e. Pulp juice, 66.5% and Mucilage, 90.2%. The study shows the waste (pulp juice and mucilage) is acidic with pH 4.75 and 3.67, respectively. Pulp juice and Mucilage had very high BOD and COD Concentration, i.e. BOD = 25,600 mg/L and COD = 45,000 mg/L for pulp juice and BOD = 19,810 mg/L, COD = 33,600 mg/L for Mucilage. The COD: BOD ratio is less than 2:1, which shows the wastes are bio-degradable. This study shows that the coffee wastes are potential environmental problems and cause water pollution due to high organic component and acidic nature. The waste was hydrolyzed by dilute H2SO4 (1, 2, 3 and 4%) and distilled water. Total sugar content of the sample was determined titrimetrically and using refractometer. iv Maximum total sugar content (90%) was obtained from hydrolysis by 3% H2SO4. The results obtained at hydrolysis of 4, 2, 1% H2SO4 and distilled water are 72.86, 76.50, 63.75 and 56.66%, respectively. Ethanol production was monitored by gas chromatography. The maximum ethanol yield of 78% was obtained from coffee waste hydrolyzed by 0.4 M H2SO4 for 1 hour hydrolysis, temperature of 100 0C and fermentation for 24 hours and initial pH of 4.5. Based on the data, it was concluded that coffee may be considered as one of the most valuable primary products in world trade, crucial to the economies and politics of many developing countries. As a consequence of big market, the reuse of the main coffee industry wastes is of significant importance from environmental and economical view points. In conclusion, this study has proposed to utilize the wet coffee processing waste to produce bio-ethanol which provides the alternative energy source from waste biomass and solves the environmental waste disposal as well as human health problem.

Optimal Superannuation Guarantee for heterogeneous groups of Australians
Creators: name: Tang, Yifu
Publisher: name: The Australian National University
Year: 2023

description: The focus of this thesis is on retirement savings decisions and their impact on individual welfare in an Australian context. Chapter 2 examines the role of the mandatory contribution rate, known as the Superannuation Guarantee (SG). The research then turns to investigate the influence of housing arrangements. Chapter 3 builds a 'cascade model' that supports the simulation of economic outcomes including housing-related variables. This model is applied in Chapter 4 to analyse the implications of housing arrangements for individual consumption outcomes and savings decisions, including the optimal SG. The key finding is that there is no single 'one-size-fits-all' optimal SG that suits all individuals; and that the optimal SG varies substantially with income levels and consumption objectives as well as other factors. This research develops a 'cascade model' that simulates integrated long-term projections for interest rates, incomes, house prices, rents, and (superannuation) fund returns intending to support life-cycle modelling. Allowing for house tenure and housing consumption choices, this research finds that the optimal SG increases with income levels for both renters and owners but is much lower for owners. This analysis provides insights into the design of the superannuation system by highlighting how the optimal SG level varies considerably with various individual attributes and is impacted by the role that is intended for social security including the Age Pension, rental assistance, and related supplements and potentially individuals' behavioural decision-making effects. The analysis shows that purchasing a home can significantly reduce the savings required for retirement through the superannuation system. This research poses the question of whether purchasing a home can substitute mandatory saving schemes in the presence of the publicly funded Age Pension.

description: The glutamine synthetase path is one of the most important metabolic pathways in luminal breast cancer cells, which plays a critical role in supplying glutamine as an intermediate in the biosynthesis of amino acids and nucleotides. On the other hand, glycolysis and its dominant substrate, glucose, are the most critical players in cancer metabolism. Accordingly, targeting these two critical paths might be more efficient in luminal-type breast cancer treatment. MCF7 cells were cultivated in media containing 4.5, 2, and 1 g/L glucose to study its effects on GLUL (Glutamate Ammonia Ligase) expression. Followingly, high and low glucose cell cultures were transfected with 220 pM of siGLUL and incubated for 48 h at 37 ºC. The cell cycle progression and apoptosis were monitored and assessed by flow cytometry. Expression of GLUL, known as glutamine synthetase, was evaluated in mRNA and protein levels by qRT-PCR and western blotting, respectively. To examine the migration and invasion capacity of studied cells exploited from wound healing assay and subsequent expression studies of glutathione-S-transferase Mu3 (GSTM3) and alfa-enolase (ENO1). Expression of GLUL significantly decreased in cells cultured at lower glucose levels compared to those at higher glucose levels. siRNA-mediated knockdown of GLUL expression in low glucose cultures significantly reduced growth, proliferation, migration, and invasion of the MCF7 cells and enhanced their apoptosis compared to the controls. Based on the results, GLUL suppression down-regulated GSTM3, a main detoxifying enzyme, and up-regulated Bax. According to the role of glycolysis as a ROS suppressor, decreased amounts of glucose could be associated with increased ROS; it can be considered an efficient involved mechanism in this study. Also, increased expression of Bax could be attributable to mTOR/AKT inhibition following GLUL repression. In conclusion, utilizing GLUL and glycolysis inhibitors might be a more effective strategy in luminal-type breast cancer therapy.

description: This research paper present develops a material for improving the fatigue strength of the bogie frame of AARLT. The purpose of this research is to compare between the current material and selected material in order to protect the bogie frame from failure. In the analysis of the research ANSYS and FEMFAT software have been used to investigate the difference of these materials. The specimen S.N curve has been used to clearly differentiate the two materials. On the basis of the modal analysis the following results has been achieved. The equivalent stress of the current material is 2.0091e^8 and 2.0037e^7 for the selected material .the minimum safety factor of current is 0.4290 and 0.4302 for the selected one. The total deformation of the two material are 0.0013168 ,0.0013329 which lead to the researcher to say that the selecting material has less deformation than the current .FEMFAT software reveal that the selected material have greater endurance limit and survival probability ,which mean the new material will be more resistant. Based on that result, it is possible to conclude that the selected material is stronger than the current material .the bogie frame that is the most important part of the bogie will be safe and can withstand the overload. The study is significant and applicable because it introduce a knowledge on the material of the bogie frame in order keep it save by improving the fatigue strength .Therefore railway corporation should give attention on the phenomena.

description: Due to Shanghai's modern history of large-scale migrant intake from surrounding areas, the Suzhou dialect is widely held to have had a profound influence on the formation of the modern Shanghainese dialect. However, the influence of the Suzhou dialect on Shanghainese remains vastly understudied. To help address this gap, this thesis explores the interactions of speakers in the late 19th and early 20th centuries in Shanghai by analysing the Suzhou dialect dialogue features contained in the novel The Sing-Song Girls of Shanghai. This study outlines the dialogue features identified in the novel: personal pronouns, discourse particles, interjections, emotional adverbs, topic markers, interrogatives, vocatives, demonstrative pronouns, and rhetorical questions. It also provides an in-depth analysis of four selected features: personal pronouns, discourse particles, interjections, and emotional adverbs. As many of these features are thought of as “empty words” in traditional Chinese linguistics, this thesis employs Natural Semantic Metalanguage to elucidate these features. In addition, the thesis also offers observations on whether these features have been retained in modern Shanghainese. By doing so, this thesis hopes to clarify the influences of the Suzhou dialect on contemporary Shanghainese.

description: We have investigated the magnetoresistance (MR) and Hall resistivity properties of the single crystals of tantalum sulfide, Ta3S2, which was recently predicted to be a new type II Weyl semimetal. Large MR (up to ~8000% at 2 K and 16 T), field-induced metal-insulator-like transition and nonlinear Hall resistivity are observed at low temperatures. The large MR shows a strong dependence on the field orientation, leading to a giant anisotropic magnetoresistance (AMR) effect. For the field applied along the b-axis (B//b), MR exhibits quadratic field dependence at low fields and tends towards saturation at high fields; while for B//a, MR presents quadratic field dependence at low fields and becomes linear at high fields without any trend towards saturation. The analysis of the Hall resistivity data indicates the coexistence of a large number of electrons with low mobility and a small number of holes with high mobility. Shubnikov-de Haas (SdH) oscillation analysis reveals three fundamental frequencies originated from the three-dimensional (3D) Fermi surface (FS) pockets. We find that the semi-classical multiband model is sufficient to account for the experimentally observed MR in Ta3S2.

description: Quantum-mechanical ab initio calculations are performed to elucidate the vibrational spectroscopic features of a common irradiation-induced defect in diamond, i.e. the neutral vacancy. Raman spectra are computed analytically through a Coupled-Perturbed-Hartree-Fock/Kohn-Sham approach as a function of both different defect spin states and defect concentration. The experimental Raman features of defective diamond located in the 400-1300 cm-1 spectral range, i.e. below the first-order line of pristine diamond at 1332 cm-1 , are well reproduced, thus corroborating the picture according to which, at low damage densities, this spectral region is mostly affected by non-graphitic sp3 defects. No peaks above 1332 cm-1 are found, thus ruling out previous tentative assignments of different spectral features (at 1450 and 1490 cm-1) to the neutral vacancy. The perturbation introduced by the vacancy to the thermal nuclear motion of carbon atoms in the defective lattice is discussed in terms of atomic anisotropic displacement parameters (ADPs), computed from converged lattice dynamics calculations.

description: After more than a decade, direct observation of the odd frequency triplet pairing state in super- conducting hybrid structures remains elusive. We propose an experimentally feasible setup that can unambiguously reveal the zero energy peak due to proximity-induced equal spin superconducting triplet correlations. We theoretically investigate a two dimensional Josephson junction in the diffu- sive regime. The nanostructure consists of a normal metal sandwiched between two ferromagnetic layers with spiral magnetization patterns. By applying an external magnetic field perpendicular to the junction plane, vortices nucleate in the normal metal. The calculated energy and spatially resolved density of states, along with the pair potential, reveal that remarkably, only triplet Cooper pairs survive in the vortex cores. These isolated odd frequency triplet correlations result in well defined zero energy peaks in the local density of states that can be identified through tunneling spectroscopy experiments. Moreover, the diffusive regime considered here rules out the possibility of Andreev bound states in the vortex core as contributors to the zero energy peaks.

description: We prove that, for M theory or type II, generic Minkowski flux backgrounds preserving $\mathcal{N}$ supersymmetries in dimensions $D\geq4$ correspond precisely to integrable generalised $G_{\mathcal{N}}$ structures, where $G_{\mathcal{N}}$ is the generalised structure group defined by the Killing spinors. In other words, they are the analogues of special holonomy manifolds in $E_{d(d)} \times\mathbb{R}^+$ generalised geometry. In establishing this result, we introduce the Kosmann-Dorfman bracket, a generalisation of Kosmann's Lie derivative of spinors. This allows us to write down the internal sector of the Killing superalgebra, which takes a rather simple form and whose closure is the key step in proving the main result. In addition, we find that the eleven-dimensional Killing superalgebra of these backgrounds is necessarily the supertranslational part of the $\mathcal{N}$-extended super-Poincaré algebra.

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

description: Railroad systems are the most widely used methods of transporting passengers in the world, so the system must be safe and comfortable. Safety is one of and critical railway system running behaivior. In this paper effect of railway vehicle parameters varation on derailment running on curved track at curved critical speed was studed. The parameters are carbody parameters(mass,rolling mass moment of inertia Ixx, pitch mass moment of inertia Iyy, yaw mass moment of inertia Izz and vertical mass center ), secondary suspenssion parameters, wheelbase distance and wheel radius. Each parameters in the study had to varying 25% upper and lower of original designed value. The study has been peformed by developing 41 DOFs, 4 axles and two bogie railway vehicle with SIMPACK software. First it was determined the curved track critical speed of the model vehicle on curved track scenario, when increasing speed above this maximum speed derailment occurs on the railway vehicle. After determination of the curved critical speed or maximum safe speed parameteric varation was analaysed. In general terms, it was concluded that carbody mass, carbody yaw mass moment of inertia(Izz), carbody height of center of mass, secondary spring longitudinal shear stiffness, wheel base and wheel radius are more sensitive to derailment, thus parameters have a roll to improve curved track critical speed and safety design of railway vehicle. Increasing or decreasing of rolling mass moment of inertia(Ixx) of carbody, pitch mass moment of inertia(Iyy) of carbody, secondary vertical damper damping and secondary lateral damper damping, decreasing secondary spring lateral shear stiveness and secondary spring vertical shear stiffness have no effect to derailment of railway vehicle running on curved track at curved critical speed. This research analyzes only the safety running behaivor of of the railway vehicle running on curved track, this means in the study was not included other running behaivior such as ride confort and wear. These parametric variation may have negative effect on other running behaivior. There fore decreasing yaw mass moment of inertia(Izz) of carbody, vertical mass center of carbody, secondary spring longitudinal shear stiveness, bogie wheelbase, wheel radius below the original value have safe to risk of derailment and improve curved track critical speed, but to take the parameters variation as positive the effect of those vriation will investigate to other running behaivior, must be improved or with in the permissible limit.

Effect of Curved Track on Rolling Contact Fatigue at Wheel-Rail Interface in Addis Ababa Light Rail Transit
Creators: name: Aregay, Haile
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The thesis presents analysis of rolling contact fatigue at the wheel-rail interface using FEM. The aim of the thesis is to determine the stress/strain and predict the fatigue life at the wheel-rail rolling contact by considering the effect of rolling contact coefficient of friction and track conditions. For this thesis the outer wheel is taken for FEA model. A three-dimensional elastic-plastic finite element model of the wheel-rail rolling contact is used to investigate the effect of coefficient of friction and track conditions. The loading and boundary conditions of the wheel-rail rolling contact is accurately shown by the FE ANSYS simulation. The FE fatigue analysis is based on the stress life analysis. The effect of mean stress correction is considered in the analysis. The effect of rolling contact friction coefficient and track conditions are also investigated in detail using the FEA. The obtained results show that the friction coefficient at the wheel-rail contact has significant effect on the fatigue life at the wheel-rail rolling contact and track condition has a large effect on the fatigue crack initiation and in all cases the minimum fatigue life is indicated at the rail rolling contact. The obtained maximum equivalent alternating stresses at the rail rolling contact at constant coefficient of friction, (μ = 0.15) at different track conditions ( at straight, transition and circular curve track paths) are 278.24Mpa, 292.7Mpa, 384.81Mpa, The results are very useful for wheel-rail rolling contact fatigue resistance design, inspection and maintenance for Addis Ababa light rail transit in Ethiopia.

description: In Ethiopia 61 percent of the rural population lacks an access to improved water sources and 62 Percent of rural households are travelling 30 minutes or more to fetch drinking water daily, mostly by child and women. This study presents the purification of water that contains saline and fluoride by using solar distillation. Three different alternatives: single slope, double slope and double slope solar still integrated with parabolic solar trough were designed and installed in the compound of Samara University and daily production and purification performance was investigated from April 6/2015 to April 8/2015. Daily yield was reduced, when water level increased from 3cm to 7cm. The 3cm water level was established for all three alternatives to compare the daily yield of the three alternatives. Single basin single slope solar still, having an area of 1mx1m basin causes the recirculation of distilled water, as a result its full production capacity couldn't be obtained.Double slope solar still integrated with parabolic solar still produces a yield 7% higher than double slope solar still of 3.16kg. The purification efficiency stills were: TDS=99.66%, Total hardness=94.7%, Total alkalinity=93.8%, Salinity=100% and fluoride=96.5%. As a result any brackish and fluoride problems currently determinant to the society to access clean water in Afar can be purified with a solar still distillation.

description: A measurement of the total $pp$ cross section at the LHC at $\sqrt{s}=8$ TeV is presented. An integrated luminosity of $500$ $μ$b$^{-1}$ was accumulated in a special run with high-$β^{\star}$ beam optics to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable $t$. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the $-t$ range from $0.014$ GeV$^2$ to $0.1$ GeV$^2$ to extrapolate $t\rightarrow 0$, the total cross section, $σ_{\mathrm{tot}}(pp\rightarrow X)$, is measured via the optical theorem to be: $σ_{\mathrm{tot}}(pp\rightarrow X) = {96.07} \; \pm 0.18 \; ({stat.}) \pm 0.85 \; ({exp.}) \pm 0.31 \; ({extr.}) \; {mb} \;,$ where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertainties in the extrapolation $t\rightarrow 0$. In addition, the slope of the exponential function describing the elastic cross section at small $t$ is determined to be $B = 19.74 \pm 0.05 \; ({stat.}) \pm 0.23 \; ({syst.}) \; {GeV}^{-2}$.

Traction Power Consumption Analysis to Investigate Freight Train Operational Speed In the case of Ethio-Djibouti Railway Corridor Awash~Sirba Kunkur~Sebaka Line Subsection
Creators: name: Shimelis, Atile
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This thesis report presents traction power consumption analysis on the existing Ethio-Djibouti electrified railway network, particularly along Awash~Sirba Kunkur~Sebaka Line Subsection. The result of the analysis is recommendation of possible freight train operational speed in the line subsection and the corridor in general to make the subsection occupancy time as short as possible increasing the frequency of services. In this report, Newton's Second law of Motion is used for train dynamics modeling. Analytical approach is used to evaluate the model as it provides a quick way to analyze train dynamic behaviors within accepted level of dynamic assumptions. Moreover, the corresponding power quality problems created due to the moving characteristic of the train are evaluated. Train dynamics analysis results show that the traction current required increases continuously and the maximum possible operational speed at the highest gradient is calculated to be 72.4kmph which is less than the freight design speed. Power consumption analysis results show, current drawn from Awash Substation are calculated to be 252A, 431A and 653A and from Sirba Kunkur 604A. Similarly, for a train running between Sirba Kunkur Substation and Sebaka Section Post current values are 238A, 384A and 374A. In both cases the first two current values are during acceleration and notch-up periods in principle which have to be the maximum values. However, even though there is an increase in current demand, the maximum requirements are 653A for 2.724min and 604A for 12.018min which are less than the 848A for 20min, the corridor traction network capacity [8] [9] [31]. The minimum catenary voltage and the maximum traction substation voltage drop are calculated to be 21.6074kV and 2.5926kV which are within the standard limits of 20kV [8] [9] [31] and 6.0kV, see Appendix C Table 2, respectively. Generally, the above train dynamics evaluation and the corresponding power consumption analysis results show that the traction power supply system is under safe condition and could provide the required power to drive the rain at the maximum targeted speed of 72.4kmph. The analysis of the train speed profile results with average train speed of 65.86kmph which improves the proposed average train speed 54kmph [9].

description: How can we discover objects we did not know existed within the large datasets that now abound in astronomy? We present an outlier detection algorithm that we developed, based on an unsupervised Random Forest. We test the algorithm on more than two million galaxy spectra from the Sloan Digital Sky Survey and examine the 400 galaxies with the highest outlier score. We find objects which have extreme emission line ratios and abnormally strong absorption lines, objects with unusual continua, including extremely reddened galaxies. We find galaxy-galaxy gravitational lenses, double-peaked emission line galaxies, and close galaxy pairs. We find galaxies with high ionisation lines, galaxies which host supernovae, and galaxies with unusual gas kinematics. Only a fraction of the outliers we find were reported by previous studies that used specific and tailored algorithms to find a single class of unusual objects. Our algorithm is general and detects all of these classes, and many more, regardless of what makes them peculiar. It can be executed on imaging, time-series, and other spectroscopic data, operates well with thousands of features, is not sensitive to missing values, and is easily parallelisable.

description: A QCD axion with a time-dependent decay constant has been known to be able to accommodate high-scale inflation without producing topological defects or too large isocurvature perturbations on CMB scales. We point out that a dynamical decay constant also has the effect of enhancing the small-scale axion isocurvature perturbations. The enhanced axion perturbations can even exceed the periodicity of the axion potential, and thus lead to the formation of axionic domain walls. Unlike the well-studied axionic walls, the walls produced from the enhanced perturbations are not bounded by cosmic strings, and thus would overclose the universe independently of the number of degenerate vacua along the axion potential.

description: In insects, chemical information is often crucial for mate recognition. The chemical signal may be perceived already from a distance or only at close range, depending on the volatility of the sex pheromone compounds. In many species, close-range mate recognition is mediated by compounds of low volatility that originate from the insects’ cuticular lipid layer. The most prominent constituents are usually non-polar hydrocarbons, but other, more polar compounds can be present as well. Upon detection, these lipids can elicit courtship behaviour. We studied mate recognition in the parasitoid wasp Muscidifurax raptorellus Kogan & Legner (Hymenoptera: Pteromalidae). In this species, courtship behaviour starts with bouts of wing fanning (high frequency wing beats while standing or walking). Once the male has mounted the female, he shows stereotypical antennal movements (antennal courtship) that lead to female receptivity signalling and copulation. We investigated the role of chemical compounds for mate recognition by evaluating the reaction of male M. raptorellus towards live conspecifics and dummies treated with whole-body extracts or with extract fractions (non-polar, intermediately polar, and polar compounds) in bioassays. Our results indicate that despite the sex specificity of cuticular hydrocarbon profiles, these compounds alone are not sufficient for mate recognition. Rather, we found that cuticular lipids of all three fractions seem to constitute the mate recognition signal, with a ternary mixture eliciting wing fanning significantly more often than single fractions. Overall, our results suggest that the three lipid fractions contribute cumulatively to the mate recognition signal.

description: Heavy metal contamination of water is a serious threat to the ecosystem. Many industries such as electroplating, metal plating, mining operation, and tanneries release wastewaters containing heavy metals into the environment. The objective of the study was to investigate the efficiency of coffee husk for the removal of heavy metals (chromium. and Lead) from synthetic wastewater. Adsorbent was prepared from coffee husk and treated with 2% formaldehyde solution in order to reduce biodegradation of organic compounds and avoid mould formation during continuous sorption. It's surface functional groups were analyzed using fourier transform infrared spectroscopy and the major peaks were observed at 3444 cm -1 -1 ,3438cm -1 and 3432cm which may representing bonded –OH groups rather than –NH group. Sorption studies were conducted in a continuous system. The sorption efficiency and adsorption capacity were studied as a function of adsorbent dose ,pH and flow rate of optimum results were found to be 99.8% at 30g, 3 and 5ml/min and 99.45% at 30g, 12 and 5ml/min which are the optimal conditions for Cr (VI ) and Pb(II ) respectively. The Sorption performance was improved as pH and flow rate decreased and adsorbent dose increased for Cr (VI ) and pH, adsorbent dose increased and flow rate decreased for Pb(II ). The highest adsorption capacity were also found to be 0.18806mg/g and 0.18mg/g at distinct pH=3 & 7.5 values for Cr (VI ) and Pb(II ) respectively and flow rate of 5ml/min.. Generally the study showed that coffee husk can be used as a good adsorbent for the removal of chromium and lead from synthetic waste water.

description: We report the first measurement of the odd-isotope fractions for barium, \fodd\, in two extremely metal-poor stars: a CEMP-r/s star \he\ (\feh\,$=-2.42\pm0.11$) and an r-II star \cs\ (\feh\,$=-2.90\pm0.13$). The measured \fodd\ values are $0.23\pm0.12$ corresponding to $34.3\pm34.3$\% of the r-process contributions for \he\ and $0.43\pm0.09$ corresponding to $91.4\pm25.7$\% of the r-process contribution to Ba production for \cs. The high r-process signature of barium in \cs\ ($91.4\pm25.7\%$) suggests that the majority of the heavy elements in this star were synthesised via an r-process path, while the lower r-process value ($34.3\pm34.3\%$) found in \he\ indicates that the heavy elements in this star formed through a mix of s-process and r-process synthesis. These conclusions are consistent with studies based on AGB model calculations to fit their abundance distributions.

description: A series of 20 newly designed (E)-1-(4-sulphamoylphenylethyl)-3-arylidene-5-aryl-1H-pyrrol-2(3H)-ones was synthesised and assessed as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors towards four human isoforms of pharmaceutical interest, that is, hCA I, II, IX and XII. The compounds displayed low to high nanomolar potency against all the isoforms. Introducing strong electron withdrawing groups at the para position of the arylidene ring increased the binding affinity to the enzyme. All compounds showed acceptable pharmacokinetic range and physicochemical characteristics as determined by computational ADMET analysis. Density Functional Theory (DFT) calculations of 3n were carried to gain understanding on the stability of the E and Z isomers. The energy values clearly indicate the stability of E isomer over Z isomer by −8.2 kJ mol−1. Our findings indicate that these molecules are useful as leads for discovering new CA inhibitors.
Garage Wastewater Turbidity Removal Using Low Cost Soil Coagulant

description: composed of clay, phosphors and oil and grease which are potential to cause harm to aquatic life, give way to invasive spices and gradually dead water bodies. Garage wastewater discharge and spillage is wide spreading but Overlooked section of pollution. Turbidity of the effluent wastewater is one and more general parameter manifesting wastewater's pollution. Though the conventional methods like skimming tanks and oil-grease traps remove turbidity including the oil and grease, but not up to the desired extent. Keeping in view of this, an effective and efficient method of turbidity removal study was made by coagulating turbid composite sample wastewater, by a jar test using locally available activated soil coagulant. And also it was analyzed then compared with the dominantly used alum coagulant which is possible to pose environmental and health impacts. The efficiency of turbidity removal by coagulation of both of these coagulants was observed considering parameters of coagulant type (Alum and Soil), dose (50 mg/l, 500 mg/l and 1000 mg/l), pH (5,7 and 9) and settling or dentation and time(15min, 30 min and 60 min). The results showed that soil from Buka was a potential coagulant with turbidity removal efficiency 97% while Alum has 98% removal efficiency turbidity in wide range of pH (5-9) and reduced Electrical Conductivity. Both of the coagulants better performed with 50 mg/l dose and neutral (7) pH conditions. After the coagulation the alum treated wastewater drops the initial pH 1.87 to acidic pH and the soil changed the pH 0.77 which is 0.53 to acidic pH and 0.24 to basic pH. In addition the use of these coagulants has changed the electrical conductivity of the raw wastewater significantly. As result this indigenous technology may be adopted at the source to remove oil and grease containing garage wastewater since it was found efficient and effective. Therefore Indigenous knowledge search and application for native problems is very important.

description: The presence of short-lived radioisotopes (SLRs) in solar system meteorites has been interpreted as evidence that the solar system was exposed to a supernova shortly before or during its formation. Yet results from hydrodynamical models of SLR injection into the proto-solar cloud or disc suggest that gas-phase mixing may not be efficient enough to reproduce the observed abundances. As an alternative, we explore the injection of SLRs via dust grains as a way to overcome the mixing barrier. We numerically model the interaction of a supernova remnant containing SLR-rich dust grains with a nearby molecular cloud. The dust grains are subject to drag forces and both thermal and non-thermal sputtering. We confirm that the expanding gas shell stalls upon impact with the dense cloud and that gas-phase SLR injection occurs slowly due to hydrodynamical instabilities at the cloud surface. In contrast, dust grains of sufficient size (> 1 micron) decouple from the gas and penetrate into the cloud within 0.1 Myr. Once inside the cloud, the dust grains are destroyed by sputtering, releasing SLRs and rapidly enriching the dense (potentially star-forming) regions. Our results suggest that SLR transport on dust grains is a viable mechanism to explain SLR enrichment.
