description: This paper presents the new act legislated in Japan for well-balanced hydrological system and urban inundation prevention. The comprehensive mitigation measures for flood control have been carried out by the government for nearly 30 years. Since it does not have a legal basis to stand on, there is a limitation to implement the measures on a mandatory basis. In order to supplement this disadvantage, the new act was constituted to bridge the existing laws such as the river law, the sewerage law, the flood prevention law and the town planning law so that the concerted effort of river administrators, sewerage administrators and local governments becomes effective. The comprehensive mitigation measures are able to be effectively promoted based on the river basin inundation prevention plan over the river or the river basin legally designated by the Minister of Land, Infrastructure and Transport, Prefectural Governor or Mayor. Especially, by applying this new act it has become much easier to impose severe restriction on the acts that hamper the function of storm water retention and infiltration. In addition to the flood control, this act will contribute to achieve the well-balanced hydrological system in urban areas as well.

description: In this paper we calculate first order radiative QCD corrections to the decay process $b\to cW^-(\to\ell^-\barν_\ell)$ of a polarized bottom quark. Taking into account both the bottom and charm quark masses, the analytical expressions given in this paper allow for a detailed analysis of the differential decay rate of the polarized quark in dependence on the polar and azimuthal angles of the lepton pair and the angle of the polarization vector of the quark relative to the momentum direction of the $W$ boson. The results are given for different polarization states of the charged lepton. In addition, we calculated nonperturbative corrections and estimated their contribution.

description: Currently, COVID-19 pandemic disease has a great capacity to increase the food insecurity of the country due to preventions of resources mobilization and movement restriction that may affect crops production, inputs and products transport. Survey was conducted during April, 2020 on current Novel Coronavirus (COVID-19) outbreak pandemic disease challenges on horticultural crops production in Arsi zone on six districts which located at different agro-ecologies. Data were collected by preparation of semi- structured questionnaires, interviews and through personal observations. The respondents have 100% information about COVID-19 pandemic disease form different information sources and they have been discussed with their families about the challenges of COVID-19 on the horticultural crops production. The respondents would be faced shortage of seeds/planting materials, lack of fertilizers, and chemicals from the market due to the impact of COVID-19. Most of the respondents, have no any others opportunities to obtain seeds, fertilizers and chemicals. As a result it was concluded that, the households required more advice, motivation, awareness creation and training from agricultural experts and other stockholders.

description: Background: In African countries including Ethiopia, each child on average hurts from five episodes of diarrhea per year. Therefore, this paper focuses on determinants of diarrheal diseases among under five children in Robe Hospital, South East Ethiopia from May-August, 2018. Methods: Health Facility based unmatched case-control study design was conducted in Robe Hospital. Interviewer administered questionnaire was used to collect data. Epi-Info version 7 and SPSS version 20 were used for data entry and analysis respectively. The proportion of case and control was assumed to 1:2 and by using the Epi Info Version 7 software the sample size was 594 (198 cases and 396 controls). Factors associated with diarrheal disease were analyzed using bivariate and multivariate logistic regression. In bivariate logistic regression, p-value of <= 0.25 was considered for enrolling variables to multiple logistic regression. Adjusted odds ratios with 95% confidence interval was calculated using a logistic regression model to controlled confounding effect and to determined predictors of the outcome. P-value < 0.05 was considered as cutoff point for statistically significance variables. Results: Multivariate logistic regression showed that presence of improved latrine [AOR: 0.35 95% CI: (0.21, 0.58)], mother/caretaker hand washing at critical time [AOR: 0.50 95% CI: (0.26, 0.95)], maternal history of diarrhea [AOR: 3.02 95% CI: (1.30, 7.02)] and age of child being 12-23 months [AOR: 4.37 (2.22, 8.62)] were found to be significant factors for under five Conclusions: The results of the study showed that factors; namely age of children, presence of improved latrine, mother history of diarrhea in the past two weeks and hand washing at critical time were significantly associated with diarrhea among children less than five years of age. Overall, educating mothers focusing on sustained behavioral changes in the use of improved latrine and hand washing at critical time is an important intervention for the prevention and control of diarrhea among children.

description: The superconductor Sr2RuO4 has been the subject of enormous interest over more than two decades, but until now the form of its order parameter has not been determined. Since groundbreaking NMR experiments revealed that the pairs are of dominant spin-singlet character, attention has focused on time-reversal symmetry breaking linear combinations of $s$-, $d$- and $g$-wave one-dimensional (1D) irreducible representations. However, a state of the form $d_{xz}+id_{yz}$ has also been proposed. We present a systematic study of the stability of various superconducting candidate states, assuming that pairing is driven by the fluctuation exchange mechanism, including a realistic three-dimensional Fermi surface, full treatment of both local and non-local spin-orbit couplings, and a wide range of interaction parameters $U,J,U',J'$. The leading superconducting instabilities are found to exhibit nodal even-parity $A_{1g} (s')$ or $B_{1g} (d_{x^2-y^2})$ symmetries, similar to the findings in two-dimensional models without longer-range Coulomb interaction which tends to favor $d_{xy}$ over $d_{x^2-y^2}$. Within the so-called Hund's coupling mean-field pairing scenario, the $E_g (d_{xz}/d_{yz})$ solution can be stabilized for large $J$ and specific forms of the spin-orbit coupling, but for all cases studied here the eigenvalues of other superconducting solutions are significantly larger when the full fluctuation exchange vertex is included in the pairing kernel. Additionally, we compute the spin susceptibility in relevant superconducting candidate phases and compare to recent neutron scattering and NMR Knight shift measurements.

description: This project develops a micro fluidic system for trapping algae in microchambers. The system comprises chambers, valves with a membrane as lock, and filters to provide a growth medium. Membrane strength, stability, deflection, thickness and filter types is studied. When deflection increases, thickness decreases. An applied pressure in the membrane decreases exponentially with time to a pressure above ambient pressure. The relation between the pressure where the growth medium leak through the valve and membrane pressure is linear. The filters tested absorbs liquid. This is avoided by a PDMS-stamp. It's possible to make a functional valve and filter system.

description: [Abridged] Most disks observed at high angular resolution show substructures. Knowledge about the gas surface density and temperature is essential to understand these. The aim of this work is to constrain the gas temperature and surface density in two transition disks: LkCa15 and HD 169142. We use new ALMA observations of the $^{13}$CO $J=6-5$ transition together with archival $J=2-1$ data of $^{12}$CO, $^{13}$CO and C$^{18}$O to observationally constrain the gas temperature and surface density. Furthermore, we use the thermochemical code DALI to model the temperature and density structure of a typical transition disk. The $6-5/2-1$ line ratio in LkCa15 constrains the gas temperature in the emitting layers inside the dust cavity to be up to 65 K, warmer than in the outer disk at 20-30 K. For the HD 169142, the peak brightness temperature constrains the gas in the dust cavity of HD 169142 to be 170 K, whereas that in the outer disk is only 100 K. Models also show that a more luminous central star, a lower abundance of PAHs and the absence of a dusty inner disk increase the temperature of the emitting layers and hence the line ratio in the gas cavity. The gas column density in the LkCa15 dust cavity drops by a factor >2 compared to the outer disk, with an additional drop of an order of magnitude inside the gas cavity at 10 AU. In the case of HD 169142, the gas column density drops by a factor of 200$-$500 inside the gas cavity, which could be due to a massive companion of several M$_{\mathrm{J}}$. The broad dust-depleted gas region from 10-68 AU for LkCa15 may imply several lower mass planets. This work demonstrates that knowledge of the gas temperature is important to determine the gas surface density and thus whether planets, and if so what kind of planets, are the most likely carving the dust cavities.

description: Potato tuberization is influenced by environmental factors like light intensity, photoperiod and temperature. Changes in these factors influence the levels of endogenous plant growth regulators. The present study was done at Kulumsa Agricultural Research Centre (KARC), Southeastern Ethiopia during the main cropping season of 2018 to determine the effect of three plant growth regulators (PGRs) (Gibberellic acid-GA 3 , Benzyl aminopurine-BAP and Benzyl adenine-BA) on yield and yield components of two potato varieties (Belete and Jalenie). Forty sprouted seed tubers with pre-treatment of the three PGRs at different concentrations were planted per plot (9m 2 ) using the recommended spacing of 75cmx30cm in an experiment using Randomized Complete Block Design (RCBD) with three replications. BAP and BA significantly (P<0.05) affected the yield and yield components of potatoes such as tuber weight, leaf area index, marketable and total tuber yield per hectare and these results were better than the effects due to GA 3 and distilled water (control). BA at low concentration (0.1mM) increased the average tuber weight over the control by 62.80%; however, BAP increased the average tuber weight at 0.2mM over the control by 59.17%. BAP and BA at 0.1mM concentration increased the leaf area index by 54.81% and 52.9%, marketable tuber yield by 67.28% and 70.55%, and total tuber yield by 61.98% and 65.81% respectively over the control. With the current findings, BAP and BA at the lowest concentration (0.1mM) concentration could be used to pre-treat seed tubers to obtain better tuber yield and yield components.

A Complete Classification of Sub-Shocks in the Shock Structure of a Binary Mixture of Eulerian Gases with Different Degrees of Freedom

description: The shock structure in a binary mixture of polyatomic Eulerian gases with different degrees of freedom of a molecule is studied based on the multi-temperature model of rational extended thermodynamics. Since the system of field equations is hyperbolic, the shock-structure solution is not always regular, and discontinuous parts (sub-shocks) can be formed. For given values of the mass ratio and the specific heats of the constituents, we identify the possible sub-shocks as the Mach number $M_0$ of the shock wave and the concentration $c$ of the constituents change. In the plane $(c,M_0)$, we identify the possible regions for the sub-shock formation. The analysis is obtained to verify when the velocity of the shock wave meets a characteristic velocity in the unperturbed or perturbed equilibrium states that gives a necessary condition for the sub-shock formation. The condition becomes necessary and sufficient when the velocity of the shock becomes greater than the maximum characteristic velocity in the unperturbed state. Namely, the regions with no sub-shocks, a sub-shock for only one constituent, or sub-shocks for both constituents are comprehensively classified. The most interesting case is that the lighter molecule has more degrees of freedom than that of the heavy one. In this situation, the topology of the various regions becomes different. We also solve the system of the field equations numerically using the parameters in the various regions and confirm whether the sub-shocks emerge or not. Finally, the relationship between an acceleration wave in a constituent and the sub-shock in the other constituent is explicitly derived.

Improved proton-transfer barriers with van der Waals density functionals: Role of repulsive non-local correlation

description: Proton-transfer (PT) between organic complexes is a common and important biochemical process. Unfortunately, PT energy barriers are difficult to accurately predict using density functional theory (DFT); in particular, the generalized gradient approximation (GGA) tends to underestimate PT barriers. Moreover, PT typically occurs in environments where dispersion forces contribute to the cohesion of the system; thus, a suitable exchange-correlation functional should accurately describe both dispersion forces and PT barriers. This paper provides benchmark results for the PT barriers of several density functionals including several variants of the van der Waals density functional (vdWDF). The benchmark set comprises small organic molecules with inter- and intra-molecular PT. The results show that replacing GGA correlation with a fully non-local vdW-DF correlation increases the PT barriers, making it closer to the quantum chemical reference values. In contrast, including nonlocal correlations with the Vydrov-Voorhis (VV) method or dispersion-corrections at the DFT-D3 or the Tkatchenko-Scheffler (TS) level has barely any impact on the PT barriers. Hybrid functionals also increase and improve the energies and the best performance is provided by a hybrid version of the consistent-exchange van der Waals density functional vdW-DF-cx. For the formic acid dimer PT system, we analyzed the GGA exchange and non-local correlation contributions. The analysis shows that the repulsive part of the non-local correlation kernel plays a key role in the PT energy barriers predicted with vdW-DF.

description: The project is based on the 3-week course Nanolithography at DTU-Nanotech, where the overall competence goal has been the introduction and understanding of Nano-Imprint Lithography (NIL). NIL can basically be described as surface manipulation of polymer resists using stamps with nanosized features for various applications. A special focus of imprinted nanostructures has been made concerning applications where the technology has environmental impact, both in terms of energy consumption and pollution. Specific examples of the later include nanoscale structures with chromatic effects facilitated without chemical dyes, hydrophobization through surface topology and generation of large scale nanostructured surfaces for production moulding etc.

Possible Implications of Relatively High Levels of Initial $^{60}$Fe in Iron Meteorites for the Non-Carbonaceous -- Carbonaceous Meteorite Dichotomy and Solar Nebula Formation
Creators: name: Boss, Alan P.
Publisher: name: arXiv
Year: 2022
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Cook et al. (2021) found that iron meteorites have an initial abundance ratio of the short-lived isotope $^{60}$Fe to the stable isotope $^{56}$Fe of $^{60}$Fe/$^{56}$Fe $\sim$ $(6.4 \pm 2.0) \times 10^{-7}$. This appears to require the injection of live $^{60}$Fe from a Type II supernova (SN II) into the presolar molecular cloud core, as the observed ratio is over a factor of ten times higher than would be expected to be found in the ambient interstellar medium (ISM) as a result of galactic chemical evolution. The supernova triggering and injection scenario offers a ready explanation for an elevated initial $^{60}$Fe level, and in addition provides a physical mechanism for explaining the non-carbonaceous -- carbonaceous (NC-CC) dichotomy of meteorites. The NC-CC scenario hypothesizes the solar nebula first accreted material that was enriched in supernova-derived nuclides, and then later accreted material depleted in supernova-derived nuclides. While the NC-CC dichotomy refers to stable nuclides, not short-lived isotopes like $^{60}$Fe, the SN II triggering hypothesis provides an explanation for the otherwise unexplained change in nuclides being accreted by the solar nebula. Three dimensional hydrodynamical models of SN II shock-triggered collapse show that after triggering collapse of the presolar cloud core, the shock front sweeps away the local ISM while accelerating the resulting protostar/disk to a speed of several km/s, sufficient for the protostar/disk system to encounter within $\sim$ 1 Myr the more distant regions of a giant molecular cloud complex that might be expected to have a depleted inventory of supernova-derived nuclides.

description: In an average combustion engine automobile, more than half of the fuel energy released upon combustion, is lost through dissipated heat. By employing the principle of absorption cooling, our project aims to utilize this excess heat to provide the cooling needed for the car’s climate system. This would in turn increase the fuel efficiency of the average car with up to 10%, as the conventional cooling system in today’s cars is a compressor driven system, that uses mechanical power provided by the engine.

description: Background: The issue of menstrual hygiene did not get proper attention. Utilization of sanitary napkins and washing genitalia are good practice of menstrual hygiene. Inappropriate management of menstrual hygiene can influence the health of the girls and expose for reproductive tract infection. Objective: To assess the knowledge, attitude, practice of menstrual hygiene and associated factors among Adama high school girls in Adama town. Method: A cross sectional study design was conducted by using multi stage random sampling technique for 604 females. Data was collected by trained data collectors from February 10 to 30, 2017 using pre-tested structured questionnaires and entered into Epi-info 7 and then exported to SPSS 21.0 for analysis. Bivariate and multivariate logistic regression analysis was done at p-value <0.05. Results: Of total respondents, 59.8% had knowledge, 48.3% had good practice and 62.8% had favorable attitude for menstrual hygiene management. Having information before menarche (AOR =3.04, 95%CI (1.66, 5.59)) and being housewives in occupation (AOR: 2.5, 95%CI (1.16, 5.42)) were factors associated with knowledge. Earning pocket money (AOR=2.6, 95%CI (1.67, 3.91)) was associated with menstrual hygiene management. Conclusion: The study revealed low level of knowledge, poor practice and unfavorable attitude of girls towards menstrual hygiene management. Maternal occupation, not earning money and not having information before attaining menarche were variables related to poor menstrual hygiene management and thus providing information and helping financially for female girls for menstrual hygiene management was highly recommended.

description: Sterile neutrinos can be produced in the early universe via interactions with their active counterparts. For small active-sterile mixing angles, thermal equilibrium with the standard model plasma is not reached and sterile neutrinos are only produced via flavor oscillations. We study in detail this regime, taking into account matter potentials and decoherence effects caused by elastic scatterings with the plasma. We find that resonant oscillations occurring at temperatures $T\lesssim 10\,\mathrm{GeV}$ lead to a significant enhancement of the sterile neutrino production rate. Taking this into account, we improve constraints on the active-sterile mixing from Big Bang nucleosynthesis and the cosmic microwave background, excluding mixing angles down to $θ_s\sim 10^{-10}-10^{-16}$ for sterile neutrino masses in the $10\,\mathrm{MeV}$ to $10\,\mathrm{GeV}$ range. We observe that if sterile neutrinos predominantly decay into metastable hidden sector particles, this process provides a novel dark matter production mechanism, consistent with the sterile neutrino origin of light neutrino masses via the seesaw mechanism.

description: It is crucial for the development of tomorrows green technologies, to ensure a sufficient engineering work-force in the future. However, application for engineering educations is low. Here I present a virtual laboratory that aims to educate and inspire young people to study greentech engineering. Furthermore, the project aims to reduce the use of chemicals and lab-equipment through replacement of some experiments with in silico simulations. In the virtual laboratory genetic engineering can be applied to develop novel enzymes for washing at lower temperatures, to develop new medicine and produce engineered bacteria that can detect and degrade heavy metals, and more.

Material studied. Holotype male. USA, Washington, Clallam County, Bogachiel, Bogachiel River, 29.VI.1974, P.A. Arnaud, Jr. (in CAS).
Description. Male. Head. Pale brown, antenna paler brown, maxillary palpus very pale brown. Eye bridge 3 facets wide. Face with 6 scattered longer and shorter setae. Clypeus with 1 seta. Maxillary palpus with 3 palpomeres; their lengths not seen in the specimen studied; palpomere 1 with 1 long sharp seta, with a dorsal pit of sensilla; palpomere 2 with 1 long sharp seta and 4 shorter truncate setae, palpomere 3 with 3 short truncate setae. Body of antennal flagellomere 4 2.8x as long as wide, the neck shorter than broad, the longest setae as long as the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 2 setae. Episternum 1 with 6 setae. Wing. Length 1.6 mm. Width/length 0.40. R1/R 0.75. c/ w 0.90. r-m longer than bM, r-m/bM 1.70, both non-setose. Halter pale brown. Legs. Pale yellowish. Coxal setae pale. Front tibial organ in large depression with vestiture in patch. Front tibial spur slightly longer than the tibial width. Abdomen. Pale brown, setae pale. Hypopygium, Figs 2 A, B. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus. Gonostylus slender with the mesial side impressed; apicomesially with a few elongated setae; with a long narrow apical tooth, with 2 long apical megasetae, with 2 mesial megasetae at the apical half, the basalmost mesial megaseta subequal with the apical ones, the apicalmost one smaller, all long and nearly straight; with two flagellate setae well basad of the mesial megasetae. Tegmen broader than long, with distinct sclerotized lateral shoulders.
Discussion. In its apical tooth, Camptochaeta filifera resembles C. mutua Johannsen, 1912, C. inflata Hippa & Vilkamaa, 1994 and C. falcidens Hippa & Vilkamaa, 1994, in having a membraneous mesial margin, but only in its basal part, not its whole length, as in the three latter species. The tooth is also relatively much shorter than in the latter species. In its tegmen, C. filifera resembles C. falcidens, but differs in having a narrower gonostylus and a different arrangement of the gonostylar megasetae, as well as in the characteristic of the apical tooth mentioned above.
Etymology. The name is derived from the Latin words, filum, thread and – fer, carrying, referring to the long setae on the mesial side of the gonostylus.

description: The study aimed to identify the major potato value chain actors, role, production constraints and its contribution for ensuring household food security. Two-stage sampling procedure was used to select respondents. The main actors were input suppliers, farmers, wholesalers, processors, retailers and consumers. 94% of the produced potato was supplied to the market while 4% of the same was used for seed for the next cropping season. The rest 2% of it was used for consumption of the household. Income from potato contributed 55% of the total household income (as it is vital element in ensuring household food security); the share of potato was 19% in ensuring household food security in the study area while the remaining goes to other crops and livestock as well as nonfarm activities. Inadequacy of inputs, lack of bargaining power and low price of potato were among the constraints. It is recommended that the government and stakeholders along the chain should igation. Moreover, pertinent actors should facilitate access for inputs and output

Robust Features of Off-Axis Gamma-Ray Burst Afterglow Lightcurves

description: The ultra-relativistic outflows powering gamma-ray bursts (GRBs) acquire angular structure through their interaction with external material. They are often characterized by a compact, nearly uniform narrow core (with half-opening angle $θ_{c,\{ε,Γ\}}$) surrounded by material with energy per unit solid angle ($ε=ε_cΘ_ε^{-a}$, where $Θ_{\{ε,Γ\}}=[1+θ^2/θ_{c,\{ε,Γ\}}^2]^{1/2}$) and initial specific kinetic energy ($Γ_0-1=[Γ_c-1]Θ_Γ^{-b}$) declining as power laws. Multi-wavelength afterglow lightcurves of off-axis jets (with viewing angle $θ_{\rm obs} > θ_c$) offer robust ways to constrain $a$, $b$ and the external density radial profile ($ρ\propto R^{-k}$), even while other burst parameters may remain highly degenerate. We extend our previous work on such afterglows to include more realistic angular structure profiles derived from three-dimensional hydrodynamic simulations of both long and short GRBs (addressing also jets with shallow angular energy profiles, whose emission exhibits unique evolution). We present afterglow lightcurves based on our parameterized power-law jet angular profiles for different viewing angles $θ_{\rm obs}$ and $k=\{0,1,2\}$. We identify a unique evolutionary power-law phase of the characteristic synchrotron frequencies ($ν_m$ and $ν_c$) that manifests when the lightcurve is dominated by emission sensitive to the angular structure of the outflow. We calculate the criterion for obtaining single or double peaked light-curves in the general case when $θ_{c,Γ}\neqθ_{c,ε}$. We emphasize how the shape of the lightcurve and the temporal evolution of $ν_m$ and $ν_c$ can be used to constrain the outflow structure and potentially distinguish between magnetic and hydrodynamic jets.
