Group 10 complexes of an unsymmetrical electron-rich diphosphine ligand
Creators: name: Zimmerman, Amanda C.
Publisher: name: University of British Columbia
Year: 2019

description: Three unsymmetrical PPC pincer-type ligand precursors, containing a terminal aryl group, for the synthesis of nickel and palladium complexes were developed. The ligand precursors were based off the ButPCP (ButPCP = C₆H₃-2,6-(CH₂P(But)₂)₂) donor set with the intent of studying the effect of the new donor atom arrangement on the chemistry at metal center. However, what quickly emerged was the ability of the terminal aryl group to participate in reactivity rendering the ligand non-innocent. Only one ligand scaffold was successfully installed on both nickel and palladium in a tridentate fashion, requiring oxidative addition of a carbon–bromine bond to the metal to generate square planar nickel(II) and palladium(II) bromide complexes. Salt metathesis reactions of the nickel(II) bromide complex with hydride and alkyl sources (methyl, ethyl and propyl) typically resulted in isolation of nickel(0) complexes as a result of reductive elimination, preceded by beta-elimination in the case of longer-chain alkyl complexes. The nickel(II) methyl complex was isolated, however reductive elimination was induced thermally. Deuterium labelling studies were consistent with a reversible beta-elimination process prior to reductive elimination. Reaction of the nickel(II) bromide complex with heteroatom-containing species resulted in nickel(0) and/or nickel(II) complexes depending on the heteroatom. Corresponding hydride and alkyl palladium(II) complexes were also synthesized with the hydride complex showing a similar propensity for reductive elimination. The palladium(II) alkyl complexes were kinetically more stable than their nickel analogues and the palladium(II) alkyl complex was isolable in each case. Reductive elimination of the terminal aryl and alkyl moieties was induced thermally and the longer-chain alkyl complexes also underwent beta-elimination followed by reductive elimination. As with nickel, deuterium labelling studies supported a reversible beta-elimination process prior to reductive elimination. Carbonylation of the palladium(II) methyl complex also induced reductive elimination. Nickel(II) alkyl complexes lacking beta-hydrogens were synthesized in an attempt to examine the alpha-elimination process from these complexes. However, they proved to be poor model complexes as they underwent alkyl aryl reductive elimination at room temperature or when heated. A nickel(II) amido complex, lacking beta-hydrogens, was also synthesized, however, this complex was also susceptible to carbon–nitrogen reductive elimination upon heating.

description: We study entanglement distribution in quantum complex networks where nodes are connected by bipartite entangled states. These networks are characterized by a complex structure, which dramatically affects how information is transmitted through them. For pure quantum state links, quantum networks exhibit a remarkable feature absent in classical networks: it is possible to effectively rewire the network by performing local operations on the nodes. We propose a family of such quantum operations that decrease the entanglement percolation threshold of the network and increase the size of the giant connected component. We provide analytic results for complex networks with arbitrary (uncorrelated) degree distribution. These results are in good agreement with numerical simulations, which also show enhancement in correlated and real world networks. The proposed quantum preprocessing strategies are not robust in the presence of noise. However, even when the links consist of (noisy) mixed state links, one can send quantum information through a connecting path with a fidelity that decreases with the path length. In this noisy scenario, complex networks offer a clear advantage over regular lattices, namely the fact that two arbitrary nodes can be connected through a relatively small number of steps, known as the small world effect. We calculate the probability that two arbitrary nodes in the network can successfully communicate with a fidelity above a given threshold. This amounts to working out the classical problem of percolation with limited path length. We find that this probability can be significant even for paths limited to few connections, and that the results for standard (unlimited) percolation are soon recovered if the path length exceeds by a finite amount the average path length, which in complex networks generally scales logarithmically with the size of the network.

description: The LHC measurements above SPS and Tevatron energies give the opportunity to test predictions of non-extensive thermodynamical picture of hadronic interaction to examine measured transverse momenta distributions for new interaction energy range. We determined Tsallis model non-extensivity parameter for the hadronization process before short-lived particles decayed and distort the initial p_t distribution. We have shown that it follows exactly smooth rise determined at lower energies below present LHC record. The shape of the q parameter energy dependence is consistent with expectations and the evidence of the asymptotic limit may be seen.

ASSESSMENT OF TEMPORAL VARIABILITY OF RAINFALL IN DIRE  DAWA, EASTERN ETHIOPIA
Creators: name: MOHAMMED HOSH ADEN
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Rain variability in space and time is one of the most relevant characteristics of tropical rain forest
that is associated with economic, social and ecological implications. Extreme rain events have
significant environmental consequences that cause considerable damages in urban as well as in
rural areas. Temporal variability in precipitation is a key factor influencing the structure and
function of semiarid ecosystems. The climate of the Dire Dawa Administration is being located
in an arid and semi-arid part of the country and dominated by various inter-related factors,
altitude being the most determinant factor and the temporal variability of precipitation affects
the runoff process. This resulted in  flash flood disasters and drought during recent years and
requires  an  urgent  course  of  mitigation  measures  to  alleviate  the  associated  problems.  This
requires detail information regarding the temporal distribution of annual and seasonal rainfall
pattern  in  the  region.  The  present  study  has  been  carried  out  for  20  different  probability
distribution {gamma (2P, 3P), generalized gamma (3P, 4P), logistic, log-logistic (2p, 3p), log
gamma, normal,  lognormal (2P, 3P), Weibull (2P, 3P), Pearson 5 (2P, 3P), pearson 6 (3P, 4P),
log-pearson 3, generalized extreme value and Gumbel’s maximum  distribution } and  associated
goodness  of  fit  test   using  Kolmogorov   Smirnov,  Anderson  Darling   and  Chi-Squared  tests.
Temporal rainfall variability is assessed using statistical trend  analysis  of the monthly, seasonal
and annual rainfall using the Mann–Kendall test, the Sen’s slope estimator and spearman’s Rho
test. It was observed that according to Kolmogorov Smirnov and Anderson Darling test,
Generalized Extreme value  distribution fits well to the rainfall data  occupying 45% and 40%
respectively and the log logistic (3p) obtained 32% according to Anderson Darling. Among these
distributions 41% of  the rainfall follows general extreme value while 24% and 18% of the DDA
rainfall gamma (2p) and log logistic (3p) distribution respectively. The best distribution for one
day maximum rainfall received during different months in a 39 year was Generalized Extreme
Value and it can be seen that April  month    received the highest amount of one day maximum
rainfall  (25%)  followed  by  January,  March  and  August  with  the  same  percent  of  (13%).  The
minimum rainfall of 27.4 mm rainfall can be expected to occur with 97.5 per cent probability and
one year return period and maximum of 125.8 mm rainfall can be received with one per cent
probability and 100 year return period. There are rising rates of precipitation in some months and
decreasing trend in some other months obtained by Mann-Kendall Test together with the Sen’s
Slope and Spearman’s Rho teast even though most of the months was not statistically significant.

description: In this letter, we reported the results of NMR study on LiFeAs single crystals. We find a strong evidence of the low temperature spin fluctuations; by changing sample preparation conditions, the system can be tuned toward an spin-density-wave (SDW) quantum-critical point. The detection of an interstitial Li(2) ion, possibly locating in the tetrahedral hole, suggests that the off-stoichiometry and/or lattice defect can probably account for the absence of the SDW ordering in LiFeAs. These facts show that LiFeAs is a strongly correlated system and the superconductivity is likely originated from the SDW fluctuations.

Year: 2015

description: Assessing availability of water  source  and land for irrigated agriculture is very important to
reach at a proper decision on  the  demand  and supply of irrigation development.   This study
was   initiated   with   the   objective  of  assessing   surface  runoff   potential   ,  land  suitability
evaluation   for  irrigation     and  crop  water  demand  of   Hargeti  river  watershed  for  spate
irrigation development  .The  surface  runoff potential  was  calculated by the soil Conservation
Service  Curve  Number  (  SCS  - CN)   method.Crop  water  demand  was  estimated  using
Hargreaves  method. To  identify potential irrigable land , irrigation   suitability factors such as
soil type,  slope, and  land cover/use, were taken  into account.    The surface  runoff  potential
Hargeti   sub  catchment  was assessed  monthly based, the result shows there is high tempora l
variability of runoff observed. The  irrigation suitability analysis o f these factors indicates  that
54 % of soil  is  marginally  suitable.  whereas  based on slope suitability  7   %  and 31%  of   the
study area is  in the range of highly   to marginally   suitable    for surface irrigation system
respectively. In terms of land cover /use,  63   % and 35%  of land cover/ use is  in  the range  of
highly to  marginally suitable. The overall analysis of these  factors  gave 29,200  ha  of irrigable
land by   surface  irrigation  system.  Based  on analysis  of surface  runoff  potential and   water
demand for selected  crop, the   potential  irrigable   land by spate irrigation  is  3682 ha, thus the
potential  can  be enhanced  through  additional  water harvesting  activities.
The struggle for coexistence : Peter Kropotkin and the social ecology of science in Russia, Europe, and England, 1859-1922
Creators: name: Johnson, Eric M.
Publisher: name: University of British Columbia
Year: 2019

description: This dissertation critically examines the transnational history of evolutionary sociology during the late-nineteenth and early-twentieth centuries. Tracing the efforts of natural philosophers and political theorists, this dissertation explores competing frameworks at the intersection between the natural and human sciences – Social Darwinism at one pole and Socialist Darwinism at the other, the latter best articulated by Peter Alexeyevich Kropotkin’s Darwinian theory of mutual aid. These frameworks were conceptualized within different scientific cultures during a contentious period both in the life sciences as well as the sociopolitical environments of Russia, Europe, and England. This cross-pollination of scientific and sociopolitical discourse contributed to competing frameworks of knowledge construction in both the natural and human sciences. I argue that the dominant theoretical framework that emerged in evolutionary sociology – what would become known as Social Darwinism – was an outcome in opposition to Socialist Darwinism rather than one that emerged through empirical evidence. The widespread rejection of Kropotkin’s Darwinian theory of mutual aid in England should be understood within this larger discursive context. As such, my project offers a reconceptualization of scientific knowledge construction by emphasizing the sociopolitical networks upon which consensus is achieved in the public sphere. This dissertation is divided into five chapters beginning with the macroscopic lens of anthropology in the context of Empire before progressing forwards in time but inwards in scope to examine the European socialists’ articulation of Darwinian science as a theory of social change, to the conflict between Social Darwinism and Socialist Darwinism, to the evolutionary mechanisms of cooperation in nature, and finally to the debate over the modes of biological inheritance.

description: This thesis assessed the performance of four blocks KDIP.as large  irrigation  systems  indeed
have  their  own  identity  and  have  a  very  important  role  in  economic development  of
many  parts  of  the  world.
Canal water delivery and flow rates, soil and crop parameters were measured and tested in the
field and in laboratory by frequent field observations, field sample takings and measurements.
Secondary data obtained from the various sources and canal operators, BWE, meteorological
agencies, interviews with members of the irrigation project staffs and farmers, data recorded
through the lives of the project and design documents of the project Due to time and budget
four blocks were selected and compared using minimum sets of performance indicators.
Any volume of irrigation water applied on irrigable area blocks was either insufficient, too
much or not the recommended water quantity and quality. Therefore in order to determine
how much irrigation water to apply was essential to revise irrigation schedule and the way in
which we managed water application uniformities, efficiencies and conditions of irrigation
and drainage canals. Lack of proper irrigation water management was one of the most im
portant problems for unexpected outcomes.
From 12 blocks kudimi with 373ha ,Chihona 617ha, Ambomesk with 812 ha and Inguiti with
393 ha due to the proximity to reservoir area and the main road from Addis to Bahirdar, their
irrigation practices, the availability of secondary data and organizational set up and with sites
of research centers were selected.. From analyzed data of performance evaluation indicators,
the result of RWS was 1.01, 6.75, 0.60 and 0.75 and RIS was 0.97, 6.58, 0.54 and 0.71 for
Kudimi, Chihona, Ambomesk and Inguiti respectively. The values of reliability were 1.00,
7.53, 0.48, 0, and 55 and for adequacy the values were 1.00, 7.53, 0.48, and 0.55.  The values
of equities were 1.56, 2.49, 0.85 and0.93 for Kudimi, chihona, Ambomesk and Inguiti blocks
respectively.  Output per cropped area was 6958.7, 8297.13, 4881.9 and 3790.63 kg/ha. And
the  value  of  the  output  per  command  area  was  58,706.03;  128,329.82;  48,472.93;  and
32,162.85 ETB/ha for kudimi, chihona, Ambomesk and inguiti respectively.   The output per
unit irrigation supply was 0.46, 0.32, 0.56 and3.78 kg/m^3. And Output per water consumed
was  3.79,  34.52;  3.5;  and  1.13  ETB/m^3  for  the  above  blocks  respectively.

Year: 2015

description: Land  use  and  land  cover  changes  in  Kulfo  River  watershed  experiences  a  lot  of  human
disturbances due to agricultural expansion, and increasing urban demand for charcoal, fuel wood
and timber; resulting in forest and land degradation. This in turn altered the hydrologic responses
of the catchment. This study was conducted to assess the hydrological response of land use/cover
change on Kulfo River flows.  In this study SWAT model was selected  as  it applies distributed
hydrologic  model  where  various  spatial  parameters  could  be  used  and  runoff  is  simulated  at
required  scale.  Spatial  data  (land  use,  DEM  and  soil)  and  meteorological  data  were  obtained
from  USGS  Satellite  image,  Ministries  of  Water  Resources,  Irrigation  and  Energy,  National
Meteorology  agency  respectively.  SWAT  model  was  used  to  simulate  stream-flow  for  land
use/land  cover  for  the  year  1985,  1995  and  2005  to  determine  the  impact  of  land  use/cover
change on Kulfo stream flow. Land use maps of 1985, 1995 and 2005 were derived from satellite
images  processed  using  ERDAS  Imagine  9.1  software.  The  model  is  calibrated  and  validated
using  historical  flow  data.  Land  cover  change  analysis  has  shown  an  increment  in  the
proportional of the Agricultural land from  11.9%  to  14.39%,  Bare land from  25.8%  to  14.14%,
Forest  from  16%  to  12.43%.  Water  body,  remain  stable,  however,  Shrub  land  increased  from
29.28%  to  36.82%  in  between  1985  to  2005.  Sensitivity  analysis  has  shown  that  the  curve
number is the most sensitive parameter that affects the hydrology of the watershed. The models
were calibrated using flow data from the 1989 to 2001 and validate from 2002 to 2008. The R
2
and Nash-  Sutcliffe  Efficient  (NSE) value for the watershed were 0.78 and 0.93 for calibration
and  0.80  and  0.78  for  the  validation  respectively.  It  has  been  concluded  that  LULC  highly
affected the runoff process in the watershed.
HYDRODYNAMICS FLOOD MODELLING IN BAROTSE  FLOODPALIN, ZAMBIA: EFFECTIVENESS OF DIGITAL  ELEVATION MODELS
Creators: name: ELIAS AWOL MOHAMMED
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The  extensive  Barotse floodplain  in western Zambia is among the most flood prone area.  This
study focused on  hydrodynamic  flood modeling to simulate flood inundation characteristics that
will  benefit  provision  of  recession  farming,  canal  management,  and  land  use  planning  in  the
Barotse floodplain.  For this study the one-dimensional hydrodynamic model  (HEC-RAS 4.1.),
HEC-GeoRAS10  (GIS extension),  ARC-GIS 10, and  Google Earth  are used.  The  SRTM 30-
m,  SRTM 90-m, and  ASTER 30-m  DEMs are first compared to  select a better DEM for model
simulation. This was done by a visual  comparison  and through objective functions using SRTM
30-m  as  reference.  The  mean  elevation  deviation  of  SRTM  90-m  ranges  from  0  to  1m  and
ASTER 30-m ranges  from  -9 to 3m.  SRTM 30-m better captured the channel geometry and the
heterogeneity  of  the  floodplain  to  a  certain  details.  ASTER  30-m  as  resulted  in  a  somewhat
exaggerated  elevation  of  river  channel  banks.  Additionally  taken  the  topographic  survey  of
Mouyowamo canal elevation as reference and the result obtained that RMSE of SRTM 30m and
SRTM  90m  is  2.99  and  ASTER  30m  is  7.28.  The  floodplain  terrain  slope  shows  the  largest
variation in ASTER 30-m and the least variation for the course DEM SRTM 90-m.  None of the
DEM  captured  the  canals  in  the  study  area.  Topographic  survey  and  Google  Earth  provided
important  information  to  correct  the  canal  cross-sections.  The  results  show  that  all  the  three
DEM sources have major limitation for the study area. SRTM 30-m DEM was used for modeling
flood inundation as it has better accuracy. The inundation depth, velocity  and extent map  were
developed  using  HEC-RAS  flood  model,  HEC-GeoRAS  and  ARC-GIS  were  integrated  to
preprocess HEC-RAS inputs and post process the model outputs. The simulated inundated extent
of  Mongu  district  (10,870km
2
)  was  6.07%,  6.39%  and  6.59%  for  5,  10  and  20  year  return
periods  respectively.  Also,  the  results  showed  that  the  Lealui  villages  (targeted  area)  are  not
inundated  with  these  return  period  floods.  This  study  was  a  first  attempt  to  model  the  flood
dynamics of the complex Brotse floodplain. To be more conclusive to use the HEC-HMS model,
the inputs of particular floodplain and channel geometry of selected areas should be surveyed in
the future.
Probing collectivity in ultra-relativistic heavy ion collision by leptons and photons

description: It has been shown that the evolution of collectivity in ultra-relativistic heavy ion collision is manifested in the variation of various HBT radii with invariant mass ($M$) extracted from the correlation functions of two lepton pairs. The value of the radial velocity ($v_r$) can be estimated from the ratio of the $p_T$ distributions of single photons to lepton pairs for various $M$ windows. It has been argued that the variation of radial flow with appropriate kinematic variables can be used as an indicator of a phase transition from initially produced partons to hadrons. We also consider the elliptic flow ($v_2^{HF}$) of the matter as probed by the single electron spectra originating from the semileptonic decays of heavy mesons. The measured values of $v_2^{HF}$ and the nuclear suppression factor ($R_{\mathrm AA}$) at RHIC energy have been reproduced simultaneously by including both the collisional and radiative processes within the scope of perturbative quantum chromodynamics. The $R_{\mathrm AA}$ and $v_2^{HF}$ have been predicted for LHC energy.

Atmospheres of massive planets and brown dwarfs as clue to distinguish between formation mechanisms
Creators: name: Palma-Bifani, Paulina
Publisher: name: Zenodo
Year: 2021

description: Short contributed talk abstract: How do we discriminate an exoplanet from a brown dwarf (BD)? This question has been fiercely debated considering definitions based on either their physical properties (like the mass or the ability to fuse deuterium) or their formation. BD usually are considered as failed stars, formed isolated or in hierarchical multiple systems. If formed as binary they might overlap in separation and mass with the population of giant planets formed in protoplanetary disks, but with a different atmospheric composition. Exploring the origin and nature of them can therefor potentially be approached by peering into the atmospheres of young, substellar (10 – 70 M_jup) objects. We intend to particularly study the carbon to oxygen ratio (C⁄O) together with the bulk properties and architectures. We analyze raw medium-resolution (R ~ 4000) SINFONI data in K-band (1.96 – 2.45 µm) from 24 young planetary-mass objects of spectral type between M5-L5. We applied the standard ESO SINFONI pipeline and used customized Python routines to further correct the data. Then we modeled the spectra with ForMoSA using different spectral grids. From the results we derived physical parameters as spectral type, effective temperature, gravity, metallicity and C/O ratio. This work provides NIR spectra and physical properties of various young planetary-mass objects which can be used as starting point to distinguish between the two populations by the imprints left on the spectra due to the formation process.

description: The paper is a study of James Joyce's Ulysses and Cubism in modern art. Both forms, as the paper presents, use similar techniques to establish multidimensionality in the work of art. In a spatial novel like Ulysses, because of its techniques, the reader is allowed to experience exactly what the characters experience as Joyce presents every aspect of the Dublin life simultaneously. A Cubist painting does the same. As the Cubist painter captures every side of the object and simultaneously presents these different views on the canvas, the spectator is therefore able to apprehend the object from every possible angle, as if he were viewing it in the studio. Both Joyce and the Cubist painter would like to have their work apprehended "spatially. It is this aesthetic similarity of Ulysses and Cubism that deserves more attention.
ADAPTATION TO CLIMATE CHANGE IN UPPER BLUE  NILE BASIN (CASE STUDY OF KOGA IRRIGATION SCHEME)

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

description: In this study, impact of climate variability and climate change on Koga irrigation scheme has been
evaluated.  In  addition,  appropriate  climate  change  adaptation  options  for  this  irrigation  scheme
have  been  evaluated  through  stakeholder  consultation.  A  single  level  –  stakeholder  consultation
was undertaken to prioritize and select the best adaptation options using a Multi- Criteria- Analysis
(MCA) and scenario analysis method. The HBV rainfall runoff model was used to quantify inflow
to Koga reservoir. The Water Evaluation And Planning model (WEAP) was applied to evaluate the
impacts of climate variability and change on the reservoir and irrigation scheme. WEAP was set
up for the designed and operational cropping patterns. High resolution (50km) and bias corrected
outputs  of  dynamical  downscaled  data  from  three  climate  models  (GFDL,  NORESM  and  MPI)
were  used  to  derive  inputs  to  HBV  and  WEAP.  The  climate  scenario  is  the  Representative
Concentration  Pathways  (RCPs)  4.5.  Under  the  designed  cropping  pattern  the  reliability  of  the
Koga  dam  is  98.77%  and  meets  almost  100%  of  the  irrigation  demand  on  annual  basis.  The
demand coverage is small in May and June which is only 96.33% and 98.46% respectively. The
reliability  and coverage  of the Koga dam did not change  when  the designed cropping pattern is
replaced with the operational cropping pattern. The NIR is expected to increase in all models due
to climate change. Under the GFDL model the largest NIR is seen on the designed crop pattern
than operational cropping pattern. Beside this the reservoir inflow is projected to decrease due to
the reduction of rainfall amount and high amount of net evaporation by  GFDL and MIP but, in
NORESM  the  inflow  will  not  significantly  change.  According  to  farmers  and  experts,  the  best
options to deal with possible impacts of climate change are to  shift to crops that require relatively
less  amount  of  water  or  less  frequent  irrigation,  use  short  duration  crop  varieties  and  water
allocation that takes in to account the development stage of the crops.
ASSESSMENT OF GROUNDWATER CONTAMMINATION BY  AGRICULTURAL CHEMICALS AND URBAN EFFLUENTS IN  ARBAMINCH AREA, SNNPR, ETHIOPIA

description: Groundwater is a major source for all purpose of water requirements and it plays a vital role
to  human  life  and  economic  activities.  But  unplanned  and  non-scientific  action    on
groundwater has led to sharp depletion  in quantity and degradation in quality  of the resource
Therefore,  the  prime  focus  of  this  study  was  to  holisticallt  understand  groundwater
contamination by  agricultural  fertilizers and sewage effluents by evaluating the groundwater
contaminant  parameters  and  their  spatial  distribution  using  geostatistical  methods  at  Arba
Minch  University  farm.  To  achieve  this  objective  a  total  of  nine  observation  wells  were
established  by  hand  auger  manually  in  study  area  for  sampling  of  groundwater.  These
groundwater  wells  samples  were  analyzed  in  the  field  for  physico-chemical  parameters
(Temperature, pH  and EC) and depth to water levels  was measured,  and in the laboratory for
parameters  such as    BOD, Nitrite, Nitrate and Phosphate. The physico-chemical parameters
result were compared to the standard guideline values as recommended by the World Health
Organizations  (WHO)  for  drinking  and  public  health  in  order  to  have  an  overview  of  the
present groundwater quality. The results of the Laboratory analysis were examined by the use
of  the  software  package  ArcGIS  and  AquaChem.  Using  GIS  interpolation  technique  with
ArcGIS  9.3,  spatial  distribution  maps  of  BOD,  Nitrate,  Nitrite  and  Phosphate  have  been
created.  Using  AquaChem  software  package,  interpretation  and  graphical  representation
methods such as Detection Summary, Map plot and scatter plot of agricultural chemicals and
sewage effluents were established.  Groundwater  level contour map  was produced by ArcGIS
for  the  identification  of  groundwater  flow  direction  to  understand  pollutant  flow  direction.
According  to  the  overall  assessment  of  the  study  area,  all  parameters  analyzed  for
agricultural  fertilizers  (Nitrate  and  Phosphate)  are  below  the  maximum  desirable  limits  of
WHO and  from the  parameters analyzed for AMU sewage effluents  contamination  BOD  is
below  the  maximum  desirable  limit  of  WHO  but  Nitrite  of  66%  samples  was  found  to  be
above the maximum desirable limit of WHO.  Groundwater flow direction was identified to
be in East-East North direction

description: We develop an iterative, numerically exact approach for the treatment of nonequilibrium quantum transport and dissipation problems that avoids the real-time sign problem associated with standard Monte Carlo techniques. The method requires a well-defined decorrelation time of the non-local influence functional for proper convergence to the exact limit. Since finite decorrelation times may arise either from temperature or from a voltage drop at zero temperature, the approach is well suited for the description of the real-time dynamics of single-molecule devices and quantum dots driven to a steady-state via interaction with two or more electron leads. We numerically investigate two non-trivial models: the evolution of the nonequilibrium population of a two-level system coupled to two electronic reservoirs, and quantum transport in the nonequilibrium Anderson model. For the latter case, two distinct formulations are described. Results are compared to those obtained by other techniques.

description: Diversion  weir  built  across  the  river  or  canal  to  divert  water  from  the   original  course.
Assessment  of  design  practice  and  performance  evaluation  of  case  study   carried  out  in
western  Oromia,  Ethiopia  on  six  selected  diversion  weir  and  analysis  the  design  method,
parameters  and  assumptions  that  make  change  the  weir  dimension  and  cause  low
performance.
Secondary  and  primary  data  are  collected  and  analyzed  for  determination  of   peak  flood

The  weir  dimensions  top  and  bottom  width,  cutoffs,  creep  length,  seepage  head and apron
thickness  were  determined  for  all  selected  weirs.  The  seepage  head  and  apron  thickness
determined  by  Bligh‟s,  Lane‟s  and  Khosla‟s  .  After  hydraulic  dimension  of  weir  design
the  estimated  exit  gradient  is  safe  under  Bligh‟s,  Lane‟s  and  Khosla‟s  with  compared  to
natural  soil  exit  gradient.  Structural  stability  analyzed  indicates  Indris,  Fite  and  Chokorsa
are  safe  at  the  hydraulic  design  and  in  the  case  of  G/Lamu,  G/Tare  and  Jalale  the  stable
value  obtain ed  after further  stability  analyzed  done by changing  the weir  bottom width.
As  performance  evaluation  revealed  that  the  designed  weir  cross  section  of  In dris,
G/Tare,  Fite  and  Chokorsa  were  accommodating   peak  flood  while  Jalale  cannot  and  flow
shift  occurred  out  of   G/Lamu   weir  cross  section.  Piping,  uplift  pressure,  scouring,  sliding,
overturning  and  over  stress  did  not  occurred on the  five  selected weir  however, in the case
of  Chokorsa  weir  downstream  floor  totally  scoured  and  burst  due  to  uplift  pressure
occurred.  In  general  the  constructed  weirs  have  no  more  engineering  design  problems
which  cause  low  performance  but  lack  of  well  schemes  administration  the  major
problems  occurred  as field  observation  result  indicates.

description: We report the detection of absorption lines by the reactive ions OH+, H2O+ and H3O+ along the line of sight to the submillimeter continuum source G10.6$-$0.4 (W31C). We used the Herschel HIFI instrument in dual beam switch mode to observe the ground state rotational transitions of OH+ at 971 GHz, H2O+ at 1115 and 607 GHz, and H3O+ at 984 GHz. The resultant spectra show deep absorption over a broad velocity range that originates in the interstellar matter along the line of sight to G10.6$-$0.4 as well as in the molecular gas directly associated with that source. The OH+ spectrum reaches saturation over most velocities corresponding to the foreground gas, while the opacity of the H2O+ lines remains lower than 1 in the same velocity range, and the H3O+ line shows only weak absorption. For LSR velocities between 7 and 50 kms$^{-1}$ we estimate total column densities of $N$(OH+) $> 2.5 \times 10^{14}$ cm$^{-2}$, $N$(H2O+) $\sim 6 \times 10^{13}$ cm$^{-2}$ and $N$(H3O+) $\sim 4.0 \times 10^{13}$ cm$^{-2}$. These detections confirm the role of O$^+$ and OH$^+$ in initiating the oxygen chemistry in diffuse molecular gas and strengthen our understanding of the gas phase production of water. The high ratio of the OH+ by the H2O+ column density implies that these species predominantly trace low-density gas with a small fraction of hydrogen in molecular form.

description: Study was carried out to determine optimum time of withholding irrigation period before
harvesting  of  sugarcane  at  Omo  Kuraz  Sugar  Development  Project,  Ethiopia.
Experiments  on  two  varieties,  N  Co  334  and  B  52  298  planted  in  adjacent  fields
characterized with  clay  soil during 2014. The  experiment  was  designated  with  two
sugarcane  varieties  (N  Co  334  and  B  52  298)  and  five  withholding  irrigation  periods
(WIPs)  treatments  for  20,  30,  40  50  and  60  days  and  the  treatment  was  laid  out  in
randomized  complete  block  design  (RCBD)  with  four  replications. The  data  on  soil
moisture content, cane height, cane weight, cane diameter, number of internodes, number
of millable canes, moisture percent cane, fiber percent, cane yield, cane yield per month,
top to bottom ratio brix in cane juice, Brix %, Pol %, purity, reducing sugars, estimated
recoverable  sugar,  estimated  sugar  yield,   and  estimated  sugar  yield  per  month were
analyzed  using  SAS  package.  Error  variances  for  most  characters  were  found to  be
homogeneous  and  the  data  were subjected  for  analysis  of  variance. The  soil  moisture
percent differed at five different WIPs with lowest at WIP for 60 days. Variation in soil
moisture was caused by occurrence of rain during WIPs for 30, 40 and 50 days. Cane
height,  cane  weight  and  number  of  internodes per  stalk  increased  significantly  at  the
subsequent  WIPs  with  maximum  at  50  to  60  days.  Millable  canes  in  plots  at  the  five
WIPs  were  on  par.  Moisture  and  fibre  percent  in  cane  decreased  and  increased
significantly at subsequent WIPs, respectively. Quality characters, top to bottom ratio of
Brix  in  juice,  Brix,  pol  or  sucrose  and  purity  percent  in  composite  juice,  and  sugar
recovery  percent  cane  differed  at  five  WIPs.  Above  quality  characters  increased
significantly at subsequence WIPs being highest at WIPs for 50 and 60 days. Reducing
sugars percent juice declined significantly with increase in days for WIPs with lowest at
WIP for 60 days. Cane yield and cane yield per month were on par at WIPs. Estimated
sugar  yield  and  sugar  yield  per  month  tons  per  hectare  increased  significantly  at
subsequent  WIPs  with maximum at WIP  for  50  and 60 days.  The  results  revealed  that
optimum period for withholding irrigation was 50 to 60 days for obtaining maximum Pol
or  sucrose  in  cane.  Therefore,  it  was  suggestive  that  irrigation  to  sugarcane  should  be
withheld  for  at  least  50  to  60  days  for  enhancing  sugar  accumulation  in  cane  before
harvesting  in  the  month  of  May  under  the  conditions  of  South  Omo  Kuraz  Sugar
Development Project.

description: We present a theoretical framework for the calculation of charge transport through nanowire-based Schottky-barrier field-effect transistors that is conceptually simple but still captures the relevant physical mechanisms of the transport process. Our approach combines two approaches on different length scales: (1) the finite elements method is used to model realistic device geometries and to calculate the electrostatic potential across the Schottky-barrier by solving the Poisson equation, and (2) the Landauer approach combined with the method of non-equilibrium Green's functions is employed to calculate the charge transport through the device. Our model correctly reproduces typical I-V characteristics of field-effect transistors and the dependence of the saturated drain current on the gate field and the device geometry are in good agreement with experiments. Our approach is suitable for one-dimensional Schottky-barrier field-effect transistors of arbitrary device geometry and it is intended to be a simulation platform for the development of nanowire-based sensors.

description: Background; - Ethiopia is one of the countries with higher maternal mortality in the world that was estimated 11,000 in 2015 alone. Birth preparedness and complication readiness (BPCR) is important measure to improve utilization of maternal health which contributes for reducing maternal mortality. BPCR is a comprehensive package aimed at promoting timely access to skilled maternal and neonatal services. But limited study was found in Addis Ababa on BP/CR Objective: - To determine the prevalence and associated factors of birth preparedness and complication readiness among pregnant women in public health centers in Addis Ababa Method: - Facility based cross-sectional study was done in selected ten health centers in Addis Ababa. Multistage sampling technique was used to select health facilities by taking clients flow chart into account. Training was given to the data collectors prior to data collection. There were ten data collectors and two supervisors. Data was collected from March to April 2019 using structured questioner which was pretested in other health center. Then data was entered to Epi-data software version 3.1 by the principal investigator and SPSS 20 software program was used to analyze the entered data. OR were used to measure association and 95% CI and P-Value<0.05 were used as predictors of significant association. Binary and multivariable logistic regression was tatted.
