description: In dealing with fetal bone growth and fetal age estimation from osteometry, the earlier osteometric studies were done from chemically preserved fetuses, photographs, radiographs and ultrasonographs which would not give perfect results. In the present study osteometry was taken directly on naturally prepared fetal ulna bones for the first time. There were six new osteometric measurements on human fetal ulna introduced. Possible osteometric measurements were taken on 912 fetal ulna bones (right and left) from 456 fetuses having age range between 11 weeks to 40 weeks of intrauterine life. Bilateral and bisexual differences were analyzed. It is found that there is positive growth trend found in fetal ulna on the basis all the osteometric measurements taken on fetal ulna. The fastest rate of growth in the length of fetal ulna was observed in females during 11 weeks to 16 weeks of the intrauterine life of human fetus. For every 1 mm in the CRL (crown- rump length), the Maximum Length of Ulna is increased by .306 mm. As there is no established scale available for fetal age estimation from fetal bones, even anatomists found difficulties to provide precise opinion regarding the age of human fetus from fetal bones in suspected murder cases. In the present study regression values were calculated and found out a formula to estimate CRL and CHL (crown-heel length) from the osteometric measurements on fetal ulna. The age estimation is a crucial factor in dealing with medico-legal cases.

description: Higher education that intentionally fosters genuinely meaningful work remains on the periphery of mainstream educational systems. Despite the abundant evidence of the life-giving impacts of educational practices that support these aspirations, there are few indications that conventional higher education systems offer much attention to this important perspective, Noting that educational explorations of these possibilities are commonly limited to graduation ceremonies, human developmentalist William Damon asks: “How can we expect that young people will find meaning in what they are doing if we so rarely draw their attention to the personal meaning and purpose of what we work at in our daily lives?” Long before the Great Resignation of the 2020s, Damon portrayed a prevailing sense of emptiness—or meaninglessness—as the pressing problem facing these students. In what follows, I introduce several pedagogical ecologies intended to increasingly support college students to engage in genuinely meaningful work post-graduation.

description: ADCIRC, a finite element circulation model for shelves, coasts and estuaries, is used
for weak constraint variational data assimilation. That is, data will be smoothed in
space and time using ADCIRC and boundary conditions as a weak constraints; the
smoother is defined in terms of a quadratic penalty functional which is composed of
dynamic, boundary condition and data error terms. The assimilation will be effected
by the Inverse Ocean Modeling system (IOM). This system solves the nonlinear
Euler-Lagrange (EL) problem using the iterated representer algorithm, which makes
large, nonlinear but functionally smooth optimization problems feasible through
Picard iterations on linear approximations of the nonlinear problem and by making
preconditioned searches in the "data subspace" at each iterate. Much of the IOM is
modular; the significant components required by the modeler are an iteration scheme
and an adjoint operator.
The iteration scheme has already been established; the purpose of this paper is to
discuss the derivation and verification of the adjoint. Owing to the scientific
purposes of data assimilation, we define the penalty functional in terms of the
primitive formulation of the shallow water equations, rather than the wave
formulation used by ADCIRC. This fundamental decision leads to a number of
difficulties in the derivation of the adjoint and consequential loss of adjoint
symmetry, and thus to a suboptimal solution. We show that this cannot be avoided
without loss of the scientific objective of the project. We also identify and
quantify the specific characteristics of the ADCIRC wave equation formulation which
preclude computing THE optimal solution, and show that the suboptimal solution we
find is still of scientific value.

description: Climate change is a worldwide issue that affects everyone livelihood. Ethiopian agriculture is heavily dependent on nature and the country‘s geographical location and topography in combination with low adaptive capacity entail a high vulnerability to adverse impacts of climate change and variability. The objectives in this study are to investigate smallholder farmers‘ perception of climate change and to assess determinants of adaptation strategies in Sire District. The study was followed a multi-stage stratified random sampling procedure, where a combination of purposive and random sampling technique were used to select respondents. A farm-level data were collected from 126 households for 2015/16 cropping season and 1983-2011 period climatic data were obtained from Ethiopian Meteorological Agency. The descriptive statistics results show that 90% of the interviewed farmer‘s perceived long-term change in temperature over 1983-2011. The rainfall distribution data imply that high monthly rainfall was recorded in July, August and September. The average annual minimum and maximum temperatures of the study area follow increasing trends while the rainfall data recorded from 1990 to 2011 show that the annual rainfall ollowed a decreasing trend over the period. For the perceived changes, about 32%-35% of respondents took remedial actions to counteract the impacts of climate change. The result of the logit model highlighted part of determinants (such as sex of household (at 5% level with adjustment to management option), education level, size of productive labor force, family size, socio-economic group, tenure security, off-farm income and agroecology) in line with the hypothesis, and other variables (such as age, soil fertility and market distance) opposing the hypothesis, as main factors that determines part of adaptations options. Then, based on the climate change perceptions and main determinant factors of this study, a corresponding government bodies and development practitioners should create awareness, develop and implement climate smart agriculture and strengthening farmers‘ adaptation and mitigation activities to survive the impact of climate change and variability.

description: Many councils and management authorities within Australia are beginning to take steps to ameliorate downstream ecosystem affects of stormwater by creating treatment systems within individual catchments and sub-catchments. Commonly, detention ponds and wetlands are used in subtropical Australia as a means of both storing and treating stormwater before in reaches downstream receiving waters. The ability of detention ponds to store and treat stormwater is well document, but past research lacks the insight into how detention ponds treat the stormwater. This research paper investigates questions of how, where and why inorganic nutrients are removed in stormwater detention ponds. Phytoplankton and Bacterioplankton were found to remove a significant amount of inorganic nutrients from the water column within the studied detention basin, with large bacterioplankton productivity indicating a huge internal nutrient source. While the stormwater detention pond studied showed considerable amount of treatment during a monitored flood event, it also showed a considerable amount of \342\200\230un traced\342\200\231 inorganic nutrient sources and sinks. These un traced sources and sinks essentially cloud the true removal potential (or performance) of detention ponds, making it difficult to assess the true inorganic nutrient removal ability of stormwater detention ponds.

description: Adverse Drug Reactions are associated with a significant morbidity and mortality and early detection of new and/or unusual adverse drug events and minimal patient exposure to such events is very crucial to health care. Lack of knowledge, giving less value for the importance of Adverse Drug Reactions reporting and not well documented research in the developing countries were problems related with Adverse Drug Reactions among health professionals. To assess the knowledge, attitude and practices on Adverse Drug Reactions reporting among health care professionals in Adama town Hospitals, East Shoa Zone , Ethiopia A cross sectional study was conducted from June 8-20, 2017 among 183 health care Professionals. Data was collected through a self- administered questionnaire from health professionals selected by simple random sampling method. Finally, data was cleaned and checked for its completeness; coded and analyzed using Statistical Package for Social Sciences (SPSS) version 20. Descriptive analysis like frequency, proportion, mean and SD were applied. Overall, 62(33.9%) of the respondents had good knowledge on Adverse Drug Reactions reporting with there were significant differences on the level of knowledge among the health professionals. Out of 86 (47.0%) respondents who had encountered with Adverse Drug Reactions, 49(57.0%) had reported. In addition, 86.3% have positive attitude towards Adverse Drug Reactions reporting. The reasons why the participants not reporting Adverse Drug Reactions were lack of reporting form 68.8%, time consuming 28.1%, reporting process creates an additional workload was 34.7%. In spite of the poor knowledge among the respondents, the study showed that majority of the health professionals had positive attitude towards Adverse Drug Reactions reporting. But there are gaps in practice of Adverse Drug Reactions reporting among health care professionals working in Adama town Hospitals; only few of them had ever reported Adverse Drug Reactions they encountered. These gaps need to be filled by intensive training and awareness creations on Adverse Drug Reactions reporting and pharmacovigillance at various levels of healthcare system by concerned bodies.

description: The SuperCDMS SNOLAB dark matter search experiment aims to be sensitive to energy depositions down to O(1 eV). This imposes requirements on the resolution, signal efficiency, and noise rejection of the trigger system. To accomplish this, the SuperCDMS level-1 trigger system is implemented in an FPGA on a custom PCB. A time-domain optimal filter algorithm realized as a finite impulse response filter provides a baseline resolution of 0.38 times the standard deviation of the noise, $σ_n$, and a 99.9% trigger efficiency for signal amplitudes of 1.1 $σ_n$ in typical noise conditions. Embedded in a modular architecture, flexible trigger logic enables reliable triggering and vetoing in a dead-time-free manner for a variety of purposes and run conditions. The trigger architecture and performance are detailed in this article.

description: Learning within public education takes place in diverse settings other than traditional classrooms. Constructivism, the dominant learning theory in Texas public education classrooms, falls short of giving those who lead musical ensembles (such as band, orchestra, choir) a solid epistemological foundation. The edusemiotic concept of coordination with the teacher competencies of Holding-Keeping-Engaging offers an alternative. The following perspective, adapted from John Quay’s synthesis of phenomenological (Heidegger) and pragmatic (Peirce and Dewey) influences, gives those who engage in the human praxis of musical ensemble making in a pedagogical context a more solid theoretical foundation. Edusemiotics addresses the interactive relationships between teachers, students, and agentive content. Three roles (process initiator, conduit for content, and error processing) allow teachers to create a setting in which students can become a grown-up subject within a musical world.

Administrative Burden in the Classroom: An Embedded Mixed Methods Study of How External Pressure Impacts the Burden of Student Success at the Community College Level

Year: 2022
Subjects: administrative burden

description: This study examines how administrative burden is evolving in college classrooms to meet external pressures focused on student success. Through a mixed methods analysis of data from a 2018 survey, this work tests how faculty and administrators view ownership of the responsibility to meet these mandates and whether it is affecting classroom approaches. The survey asked community college administrators and faculty in Texas about their views of the student’s role in student success and how external pressure affects classroom dynamics. Results suggest a shift of burden for student success from the student (citizen) to faculty (bureaucrat) resulting in part from external pressure. This could cause negative consequences with the potential for negative ramifications that create conflictual relationships in the classroom and institution. These views create a higher education administrative landscape where the bureaucrat (faculty) sees the citizen (students) in a negative light, causing resentment and overall negative administrative behavior.

description: We report the temperature dependence of the Yb valence in the geometrically frustrated compound $\mathrm{YbB_4}$ from 12 to 300 K using resonant X-ray emission spectroscopy at the Yb $L_{α_1}$ transition. We find that the Yb valence, $v$, is hybridized between the $v=2$ and $v=3$ valence states, increasing from $v=2.61\pm0.01$ at 12 K to $v=2.67\pm0.01$ at 300 K, confirming that $\mathrm{YbB_4}$ is a Kondo system in the intermediate valence regime. This result indicates that the Kondo interaction in $\mathrm{YbB_4}$ is substantial, and is likely to be the reason why $\mathrm{YbB_4}$ does not order magnetically at low temperature, rather than this being an effect of geometric frustration. Furthermore, the zero-point valence of the system is extracted from our data and compared with other Kondo lattice systems. The zero-point valence seems to be weakly dependent on the Kondo temperature scale, but not on the valence change temperature scale $T_v$.

description: Wheat is largely grown in the highlands of Ethiopia. However, its productivity is very low due to plant nutrients limitations in the soil and weed infestation and low use of external inputs such as fertilizers and pesticides. Thus, the study was conducted in 2015/16 main cropping season under Ethiopian Seed Enterprise in Ardaita Seed Farm to evaluate the effect of foliar application of urea fertilizer and post emergence herbicide on performances of bread wheat. The experiment constituted seven treatments which were arranged in a randomized complete block design (RCBD) with three replications. Urea fertilizer were sprayed as a foliar combined with post emergence herbicide (Pallas 45OD) at different rates (10, 20, 30, 40 and 50 kg ha -1 ), 50 kg ha -1 urea fertilizer was sprayed foliarly with pure water/without any post emergence herbicide (weedy check for comparison) and the control treatment was applied with only 50 kg ha -1 granular urea at sowing on soil and post emergence herbicide Pallas 45OD 0.5 lt ha -1 . The parameters recorded on the crop were grouped into agronomic and yield performances of wheat and weed components. The results of the experiment indicated that, there were significant differences for non-fertile tillers, number of spikes m -2 , biological yield, grain yield, harvest index, straw yield, fertile tiller and grain per spike, but plant height and thousand grain yield showed non-significant difference. This, study showed that combined application of urea fertilizer and Pallas had a significant effect on most agronomic and yield parameters. However, for most weed and weed component parameters the result did not show significant difference, except pre and post application weed density, pre and post emergence weed control efficiency, and grass and broad leave weeds dry weight. The result of the experiment were shown that more number of grain per spike (37) and higher yield (50 qt ht -1 ) were recorded in plots treated with 40 kg ha -1 urea along 0.5 lt ha -1 Pallas. Higher biological yield was also recorded from plants treated with 40 kg ha -1 urea along 0.5 lt ha -1 Pallas. The plants treated with 40 and 30 kg ha -1 urea along 0.5 lt ha -1 Pallas was also shown the best economic returns. Thus, it could be concluded that the combined application of 40 kg ha -1 urea and 0.5 lt ha -1 Pallas significantly increases the wheat production in the study areas and the like. This experiment also needs to be repeatedly tested in order to clearly understand and confirm the right nitrogen fertilizer rate, concentration and application time of urea fertilizer and post emergence herbicide for the better performances of wheat under different varieties of the crop in different areas.

description: In numerical modelling of rainfall caused runoff in urban sewer systems an essential parameter is the hydrological reduction factor which defines the percentage of the impervious area contributing to the surface flow towards the sewer. As the hydrological processes during a rainfall are difficult to determine with significant precision the hydrological reduction factor is implemented to account all hydrological losses except the initial loss. This paper presents an inconsistency between calculations of the hydrological reduction factor, based on measurements of rainfall and runoff, and till now recommended literary values for residential areas. It is proven by comparing rainfall-runoff measurements from four different residential catchments that the literary values of the hydrological reduction factor are over-estimated for this type of catchments. In addition, different catchment descriptions are presented in order to investigate how the hydrological reduction factor depends on the level of detail regarding the catchment description. When applying a total survey of the catchment area, including all possible impervious surfaces, a hydrological reduction factor of approximately 0.5 for residential areas with mainly detached houses is recommendable - contrary to the literary recommended values of 0.7 - 0.9.

description: Coronal plumes are long, ray-like, open structures, which have been considered as possible sources for the solar wind. Their origin in the largely unipolar coronal holes has long been a mystery. Earlier spectroscopic and imaging observations revealed blue-shifted plasma and propagating disturbances (PDs) in plumes that are widely interpreted in terms of flows and/or propagating slow-mode waves, but these interpretations (flows vs waves) remain under debate. Recently we discovered an important clue about plume internal structure: dynamic filamentary features called plumelets, which account for most of the plume emission. Here we present high-resolution observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) and the Interface Region Imaging Spectrograph (IRIS) that revealed numerous, quasiperiodic, tiny jets (so-called jetlets) associated with transient brightening, flows, and plasma heating at the chromospheric footpoints of the plumelets. By analogy to larger coronal jets, these jetlets are most likely produced within the plume base by magnetic reconnection between closed and open flux at stressed 3D null points. The jetlet-associated brightenings are in phase with plumelet-associated PDs, and vary with a period of about 3 to 5 minutes, which is remarkably consistent with the photospheric/chromospheric p-mode oscillation. This reconnection at the open-closed boundary in the chromosphere/transition region is likely modulated or driven by local manifestations of the global p-mode waves. The jetlets extend upward to become plumelets, contribute mass to the solar wind, and may be sources of the switchbacks recently detected by the Parker Solar Probe.

description: ABSTRACT The U.S. EPA\342\200\231s Urban Watershed Management Branch is responsible for developing and demonstrating technologies and methods required to manage the risk to public health, property and the environment from wet weather flows (WWF) in urban watersheds. The activities are primarily aimed at restoring surface waters in the context of water quality uses intended for aquatic life and recreation. WWFs include combined sewer overflow (CSO), sanitary sewer overflow (SSO) and urban storm water. The primary goals of the research are development of: (1) watershed management strategies and associated models integrating area-wide WWF control for groundwater and surface water protection; (2) multi-purpose WWF methods, practices, and technologies including new and retrofit designs for drainage, flood, pollution, erosion and sedimentation control, for management of contaminated sediments in sewers; (3) pretreatment requirements for adequate WWF disinfection; and, (4) protocols for measuring WWF control program effectiveness. The overall direction of the program is geared to developing novel approaches for controlling WWFs and the integration of watershed based urban wet weather controls in mixed land-use watersheds for resolving water quality impairments as well as integration with drinking water source water protection. This paper addresses select projects and products related to these activities, especially the ongoing research activities related to best management control technologies for urban stormwater generated pollution control.

description: It is believed that education, which is greatly influenced by the practice of teacher education, has a significant impact up on the success of any individual and a nation. Hence, to improve the quality of education in a nation, it is important to improve the quality of teacher education in that nation. This paper is intended to examine whether teacher education practices in Ethiopia address the problems and realities of the Ethiopian educational system and to assess whether the assumptions and practices of the Ethiopian teacher education complements with modern perspectives. To achieve this purpose, the teacher education program is analyzed against empirical evidences. Furthermore, the study has explored the challenges faced in the implementation of the teacher education program. To this end, trainee teachers, teachers, teacher educators, concerned others and pertinent documents were used as sources of data. Data were collected from different sources using document analysis, interview and observation. Using Hatch’s interpretive data analysis model I have examined the data closely in order to find constructs, themes and patterns that can be used to describe and explain the phenomena being studied. Finally, I came to understand that the teacher education practice in Ethiopia is seriously entangled with many problems associated with recruitment, training and education, development of pedagogical content knowledge and practice-teaching. The implication of this study has illuminated ways to resolve the problems observed.

description: This paper presents a dynamic mathematical model that describes the fate and transport of two selected xenobiotic organic compounds (XOCs) in a simplified representation of an integrated urban wastewater system. A simulation study, where the xenobiotics bisphenol A and pyrene are used as reference compounds, is carried out. Sorption and specific biological degradation processes are integrated with standardised water process models to model the fate of both compounds. Simulated mass flows of the two compounds during one dry weather day and one wet weather day are compared for realistic influent flow rate and concentration profiles. The wet weather day induces resuspension of stored sediments, which increases the pollutant load on the downstream system. The potential of the model to elucidate important phenomena related to origin and fate of the model compounds is demonstrated.

Discussion. In having a slender gonostylus with straight mesial megasetae, Camptochaeta winchesteri most resembles C. kajsae, but is distinguished in having these megasetae more apical in position, a much larger apical tooth of the gonostylus and a conical, laterally acuminate, not roundish, tegmen.
Etymology. The species is named after its collector, the Canadian entomologist Neville Winchester.

description: We present evidence that it is unlikely that the streaming instability (SI) can form planetesimals from mm grains inside axisymmetric pressure bumps. We conducted the largest simulation of the SI so far (7 million CPU hours), consisting of a large slice of the disk with mm grains, a solar-like dust-to-gas ratio ($Z = 0.01$), and the largest pressure bump that does not cause gravitational instability (GI) in the particle layer. We used a high resolution of $1000/H$ to resolve as many SI unstable modes as possible. The simulation produced a long-lived particle over-density far exceeding the SI criteria (i.e., a critical solid abundance to headwind parameter ratio $Z/Π$) where strong clumping would occur if these conditions were present over an extended region of the disk; yet we observed none. The likely reason is that the time it takes particles to cross the high-$Z/Π$ region ($t_{\rm cross}$) is shorter than the growth timescale of the SI ($t_{\rm grow}$). We propose an added criterion for planetesimal formation by the SI -- that $t_{\rm cross} > t_{\rm grow}$. We show that any bump larger than the one in this run would form planetesimals by the GI instead of the SI. Our results significantly restrict the pathways to planet formation: Either protoplanetary disks regularly form grains larger than 1~mm, or planetesimals do not form by the SI in axisymmetric pressure bumps. Since bumps large enough to induce the GI are likely Rossby-wave unstable, we propose that mm grains may only form planetesimals in vortices.

description: Nitrogen is the most important plant nutrient for crop production and grain quality of malt barley improvement; but the yield and quality of malt barely produced in Ethiopia is very low due to nutrients diminished from the soil. A field experiment was conducted at Digelu–Tijo District, Southeastern Ethiopia to evaluate the effect of different rates of nitrogen on yield and protein content of two malt barley varieties in 2015/16 cropping season. Factorial arrangements of the two malt barley varieties (Grace and Traveler) and six nitrogen rates (0, 19.0, 30.5, 42.0, 53.5 and 65.0 kg N ha -1 ) were laid out in a randomized complete block design with three replications. Nitrogen rate had significant (P<0.05) effect on days to physiological maturity, plant height, tiller number, grain per spike, spike length, grain yield, biological yield, straw yield, harvest index and grain protein content. Variety had significant (P<0.05) influence on days to physiological maturity, plant height, spike length, grain per spike and thousand kernel weights. Their interaction showed significant (P<0.05) influences only on grain per spike and harvest index. When nitrogen fertilizer rate increased from 0 to 65 kg ha -1 , the growth, yield and quality components were significantly increased with corresponding increase of grain yield from 17.8 to 58.8 quintals. The responses of malt barley varieties to applied nitrogen fertilizer rate increased with respect to growth, grain yield and yield components. Thus, irrespective of varieties, the highest net benefit of 38481.55 Birr ha -1 with acceptable protein content (11.3%) was recorded at nitrogen fertilizer rate of 65 kg ha -1 in the study area. Generally, from the study result, it can be concluded that the farmer in the study area can produce optimum grain yield and quality of malt barley varieties at the application rate of 65 kg ha -1 of nitrogen fertilizer in the study area.However, further studies should be done using more levels of nitrogen at different seasons and locations through integrating with other fertilizer types to reach at dependable conclusion.
