description: Sólo en la segunda mitad del siglo XVI el Mar Báltico se convertiría en espacio de interés para España y ello obligado por el desarrollo de la guerra con las provincias sublevadas en Flandes. La problemática báltica aparecerá durante ochenta años gradualmente pero con cada vez mayor fundamento en las diferentes concepciones de guerra militar y económica con los holandeses. El desarrollo de este proceso lo presento analizando los diferentes proyectos económicos y militares así como las actuaciones diplomáticas que unían la política de España con la zona del Mar Báltico. La primera etapa fueron las actuaciones de España que tuvieron como objetivo el corte del suministro de cereal y madera del Báltico a las provincias sublevadas y la obtención de apoyo de la flota sueca (entre otras las actuaciones de Luis de Requesens, Alejandro Farnesio, Francisco de Eraso, Pontus de la Gardie, Jean Allard, Mikolaj Woythe, Stanisław Sobocki, Juande Borja, Bento Núñez) así como la intensificación del comercio de la Hansa con los puertos ibéricos. Esta etapa se cierra con la concepción de apoderamiento por España con la colaboración de Polonia del puerto sueco de Elfsborg (1595-1595 elaborada en la corte polaca por el nuncio Germanico Malaspina y el embajador extraordinario Francisco de Mendoza) así como con el tratado comercial con la Hansa firmado en el ano 1607. Objeto de análisis son también los memoriales elaborados por los comerciantes y arbitristas, que mostraban la importancia estratégica del Báltico (entre otros Joaquin Hopperus, Diego López Sueyro, Alberto Struzzi -proyecto luso-polaco de compañía comercial-, Antony Sherley). La culminación de estas experiencias fue la creación del Almirantazgo de los Países Septentrionales en 1624 y el gran proyecto báltico elaborado por Olivares, que tenía que conducir al apoderamiento del estrecho del Sund y del comercio en la zona báltica.
Four-of-a-kind: Characterising the HR 8799 system with GRAVITY
Creators: name: Nasadkin, Evert
Publisher: name: Zenodo
Year: 2021

description: The four planets of HR8799 provide a unique opportunity to study the atmospheres of young, giant exoplanets with a shared formation history. In order explore these atmospheres, we use new data obtained with VLTI/GRAVITY as part of the ExoGRAVITY campaign, combined with data from SPHERE, GPI, CHARIS, ALES and OSIRIS in order to provide the best picture of the planetary atmospheres across a broad wavelength range. Using petitRADTRANS in a Bayesian retrieval framework, we compare a suite of state-of-the-art models applied to each of the targets in order to measure atmospheric properties such as metallicity, molecular abundances, and the C/O ratio. In this talk I will describe the data processing and modelling efforts which allow us to peer into the atmospheres of the HR8799 planets, and will outline the steps needed to tie the newly retrieved planetary properties to the formation history of the system.
Analysis of wall-modelled particle/mesh PDF methods for turbulent parietal flows

description: Lagrangian stochastic methods are widely used to model turbulent flows. Scarce consideration has, however, been devoted to the treatment of the near-wall region and to the formulation of a proper wall-boundary condition. With respect to this issue, the main purpose of this paper is to present an in-depth analysis of such flows when relying on particle/mesh formulations of the probability density function (PDF) model. This is translated into three objectives. The first objective is to assess the existing an-elastic wall-boundary condition and present new validation results. The second objective is to analyse the impact of the interpolation of the mean fields at particle positions on their dynamics. The third objective is to investigate the spatial error affecting covariance estimators when they are extracted on coarse volumes. All these developments allow to ascertain that the key dynamical statistics of wall-bounded flows are properly captured even for coarse spatial resolutions.
Light scalar mesons and charmless hadronic $B_c \to SP, SV$ decays in the perturbative QCD approach

description: In this work, based on the assumption of two-quark structure of the scalars, the charmless hadronic $B_c \to SP, SV$ decays(here, $S$, $P$, and $V$ denote the light scalar, pseudoscalar, and vector mesons, respectively) are investigated by employing the perturbative QCD(pQCD) factorization approach.From our numerical evaluations and phenomenological analysis, we find that (a) the pQCD predictions for the {\it CP}-averaged branching ratios(BRs) of the considered $B_c$ decays vary in the range of $10^{-5}$ to $10^{-8}$, which will be tested in the ongoing LHCb and forthcoming Super-B experiments, while the {\it CP}-violating asymmetries for these modes are absent naturally in the standard model because only one type tree operator is involved; %% (b) analogous to $B \to K^* η^{(\prime)}$ decays, $Br(B_c \to κ^+ η) \sim 5 \times Br(B_c \to κ^+ η^\prime)$ in the pQCD approach, which can be understood by the constructive and destructive interference between the $η_q$ and $η_s$ contributions to the $B_c \to κ^+ η$ and $B_c \to κ^+ η^\prime$ decays, however, $Br(B_c \to K_0^*(1430) η)$ is approximately equal to $Br(B_c \to K_0^*(1430) η')$ in both scenarios because the factorizable contributions from $η_s$ term play the dominant role in the considered two channels; %% (c) if $a_0(980)$ and $κ$ are the $q\bar q$ bound states, the pQCD predicted BRs for $B_c \to a_0(980) (π, ρ)$ and $B_c \to κK^{(*)}$ decays will be in the range of $10^{-6} \sim 10^{-5}$, which are within the reach of the LHCb experiments and could be measured in the near future; and %% (d) for the $a_0(1450)$ and $K_0^*(1430)$ channels, the BRs for $B_c \to a_0(1450) (π, ρ)$ and $B_c \to K_0^*(1430) K^{(*)}$ modes in the pQCD approach are found to be $(5 \sim 47) \times 10^{-6}$ and $(0.7 \sim 36) \times 10^{-6}$, respectively.

The conceptual, the romantic, and the nonhuman : the SÚM group and the emergence of contemporary art in Iceland, 1965-1978
Creators: name: Árnadóttir, Heiða Björk
Publisher: name: University of British Columbia
Year: 2020

description: This dissertation considers the emergence of contemporary art practices in Iceland through the activities of the artist collective SÚM between 1965 and 1978. The founding of SÚM in 1965 brought forth, for the first time, a generation of Icelandic artists whose practices closely correspond to that of experimental artists globally, especially those aligned with Fluxus and conceptual art. As I highlight, this relied on Iceland’s belated modernization and changes to the country’s geopolitical status in the twentieth century, as well as on global efforts to decentralize the artworld. And yet, SÚM’s challenge to the definition of the art object is also uniquely configured through the artists’ complicated relationship to the local tradition of landscape painting and the concomitant romantic nationalist discourse which had shaped Icelandic self-identity, cultural practices and discourses since the turn of the twentieth century. In particular, SÚM’s practice developed through a critical engagement with the idealized place of nature in Icelandic national identity—a critique which sought to complicate the boundary between nature and culture. SÚM artists’ efforts to subvert Icelandic nationalist ideology and artistic tradition are complicated, however, by their alliance with the postwar political resistance movement against the growing economic and cultural influence of the United States in Iceland as well as its neocolonial practices globally. This led the artists to situate their work in relation to a specific, yet ill-defined, local Icelandic way and sense of being. Often characterized in terms of a “poetic” or “romantic” attitude, this typically focuses on the centrality of the natural in the work of prominent members of SÚM, their engagement with “premodern” Icelandic cultural traditions, folk belief and art, and their suggestions for an intuitive or emotional basis for their practice. Highlighting the dialectical tension between the globalizing and localizing impulses of SÚM, I argue that to understand the specificity of Icelandic contemporary art, one must consider the degree to which its emergence, through SÚM, was produced within the context of the country’s changing geopolitical position and its longer history as a peripheral territory within the Danish colonial empire.

description: The effects of "quark sea" in determining the flavor structure of the octet baryons have been investigated in the chiral constituent quark model (\chiCQM). The \chiCQM is able to qualitatively generate the requisite amount of quark sea and is also known to provide a satisfactory explanation of the proton spin and related issues in the nonperturbative regime. The Bjorken scaling variable x has been included phenomenologically in the sea quark distribution functions to understand its implications on the quark sea asymmetries like \bar d(x)-\bar (x), \bar d(x)/\bar u(x) and Gottfried integral for the octet baryons. The results strengthen the importance of quark sea at lower values of x.

description: Moment frames are one of the most widely used structural steel systems, especially for residential use. In the design of such structures, lateral seismic loads and different gravitational loads play a role which according to most design regulations about such structures for the convenience of designers, seismic design spectra and the amount of gravitational loads are determined. Since the forces in the model play an essential role in the design of sections and optimization of materials, especially for high-rise Buildings, in this study using the Site Special design Spectra for 6 different sites in Tehran with Different seismicity and soil types are obtained and using the periodic intervals intended for them, spectral acceleration and final base shear are calculated and according to the loading combinations, the final force is obtained for adding each floor to the model. The results show that the total force of the model increases linearly with the increase of each floor with very high accuracy and the total base shear acts as 2 ascending lines with the increase of the floors, but the force from per added floor for models up to 13 is ascending classes, 4 to 10 descending classes and from 11 to 66 floors is almost constant.

description: Gauge theories establish the standard model of particle physics, and lattice gauge theory (LGT) calculations employing Markov Chain Monte Carlo (MCMC) methods have been pivotal in our understanding of fundamental interactions. The present limitations of MCMC techniques may be overcome by Hamiltonian-based simulations on classical or quantum devices, which further provide the potential to address questions that lay beyond the capabilities of the current approaches. However, for continuous gauge groups, Hamiltonian-based formulations involve infinite-dimensional gauge degrees of freedom that can solely be handled by truncation. Current truncation schemes require dramatically increasing computational resources at small values of the bare couplings, where magnetic field effects become important. Such limitation precludes one from `taking the continuous limit' while working with finite resources. To overcome this limitation, we provide a resource-efficient protocol to simulate LGTs with continuous gauge groups in the Hamiltonian formulation. Our new method allows for calculations at arbitrary values of the bare coupling and lattice spacing. The approach consists of the combination of a Hilbert space truncation with a regularization of the gauge group, which permits an efficient description of the magnetically-dominated regime. We focus here on Abelian gauge theories and use $2+1$ dimensional quantum electrodynamics as a benchmark example to demonstrate this efficient framework to achieve the continuum limit in LGTs. This possibility is a key requirement to make quantitative predictions at the field theory level and offers the long-term perspective to utilise quantum simulations to compute physically meaningful quantities in regimes that are precluded to quantum Monte Carlo.

description: Radiation Reaction (RR) effects in the interaction of an ultra-intense laser pulse with a thin plasma foil are investigated analytically and by two-dimensional (2D3P) Particle-In-Cell (PIC) simulations. It is found that the radiation reaction force leads to a significant electron cooling and to an increased spatial bunching of both electrons and ions. A fully relativistic kinetic equation including RR effects is discussed and it is shown that RR leads to a contraction of the available phase space volume. The results of our PIC simulations are in qualitative agreement with the predictions of the kinetic theory.

Much has been written of the migratory agricultural laborer and much of the immigrant laborer - Chinese, Filipino, Japanese, and Mexican. Sections of the bibliography are devoted to these two classes of laborers, while another section deals with the sharecropper of the Southern and Southwestern States. Child labor has a large amount of material devoted to it, while a smaller section deals with women as agricultural workers. References to material relating to strikes and labor unrest among agricultural workers, so prevalent during the past few years, have been included.
Exoplanets in Our Backyard: What Can We Learn from the Terrestrial Planetary Bodies?
Creators: name: Head, James
Publisher: name: Zenodo
Year: 2021

description: The terrestrial planetary bodies, the Earth, Moon, Mercury, Venus and Mars, provide geologic records that hold clues to the origin and evolution of primary and secondary planetary atmospheres on exoplanets. What stochastic and evolutionary events shaped the nature of primary atmospheres, and what can we learn from the preserved geological record about the nature of secondary atmospheres and planetary climate evolution? How can this information help further define the interpretive parameter space for understanding the nature of exoplanetary atmospheres? Lessons learned from each terrestrial planetary body, outstanding questions, and potential results from upcoming missions are reviewed for their relevance to understanding both terrestrial-planet-like exoplanets, and for how exoplanetary observations can assist in the current and future understanding of the inner Solar System.

description: We propose that acousto-optical coupling of the electric field to strain fields around defects in disordered $^4$He is causing an increase of the dielectric function with decreasing temperature due to the arrested dynamics of defect excitations. A distribution of such low-energy excitations can be described within the framework of a glass susceptibility of a small volume fraction inside solid $^4$He. Upon lowering the temperature the relaxation time $τ(T)$ of defects diverges and an anomaly occurs in the dielectric function $ε(ω, T)$ when $ωτ(T) \sim 1$. Since $ε(ω, T)$ satisfies the Kramers-Kronig relation, we predict an accompanying peak in the imaginary part of $ε(ω, T)$ at the same temperature, where the largest change in the amplitude has been seen at fixed frequency. We also discuss recent measurements of the amplitude of the dynamic dielectric function that indicate a low-temperature anomaly similar to the one seen in the resonance frequency of the torsional oscillator and shear modulus experiments.

We study the local conditions for a generalized Kahler manifold to be a generalized Calabi-Yau manifold and we derive a non-linear PDE that the generalized Kahler potential has to satisfy for this to be true. This non-linear PDE can be understood as a generalization of the complex Monge-Ampere equation and its solutions give supergravity solutions with metric, dilaton and H-field.

Social integration in the context of the new patterns of migration
Creators: name: Mieriņa Inta
Publisher: name: Zenodo
Year: 2021

description: Recommendations The study confirms the premise that has recently also been increasingly voiced in foreign publications, that the host society plays the most important role in fostering integration. In order to avoid the isolation of migrants in professional, international or ethnic bubbles, it is important to provide opportunities for meaningful contacts with the local community and to promote openness. The bonds of friendship that develop can encourage migrants to become more deeply rooted in the host society. Secondly, the analysis clearly shows that when the future of a migrant, including the length and possibility of remaining in a given country, is uncertain, the motivation to invest time and effort in integration is reduced. It is therefore important on the part of the state to give migrants as much long-term certainty as possible and a more stable basis for planning their future whenever possible. Thirdly, there is a need to review integration indicators traditionally used in international comparisons (e.g. MIPEX) in the context of today’s complex migration patterns. The findings call for ‘more mobile thinking’ (Shubin & Dickey, 2013) and a relationship-based, dynamic and transformative interpretation of integration that takes into account the unpredictable trajectories of mobility and integration and recognises the diverse needs of migrants. Fourth, it is desirable that attempts to promote integration become more holistic, open and «migrant-centred». Rather than trying to squeeze migrants into a formally defined ‘framework’, it is necessary to listen to and take into account their different expectations, to help them experience their roots, to support their life strategies and to exploit the potential of international mobility. This is the only way to reduce the politicised nature of integration, the assimilationist orientation and the disconnection of integration indicators from the real experience of migrants. Finally, the proposed conceptual model can help theorists to better illustrate contemporary migrants' adaptation processes beyond the outdated and inappropriate narratives of ‘assimilationism’ and ‘multiculturalism’.

description: Basing on a semiclassical picture of dyons, we present a nonperturbative model of a pure Yang--Mills theory at any temperatures, for an arbitrary simple gauge group. We argue that at low temperatures dyons drive the Yang--Mills system for all groups to a phase where the `eigenphases' of the Polyakov line are, as a vector, proportional to the Weyl vector being the half sum of positive roots. For most gauge groups it means confinement, in particular for `quarks' in any N-ality nonzero representation of the SU(N) gauge group. At a critical temperature there is a 1st order phase transition for all groups (except SU(2) where the transition is 2nd order), characterized by a jump of Polyakov lines, irrespectively of whether the gauge group has a nontrivial center, or not.

description: Many  diversion  headwork  and  pumps  for  small  scale  irrigation  (SSI)  schemes  have  been
designed and constructed in preceding years. Some of them are performing successfully, but
it has been observed in various reports and field observations that some of the  schemes have
failed to serve the purpose for which they are designed. Therefore, it is important to evaluate
the  failures  and  design  practices  of  the  two  selected  irrigation  schemes  (Awushoana  and
Kecha SSI) in Soro woreda. An attempt has been made to understand the design problems
based  on  hydrologic,  hydraulic  and  structural  analysis  for  these  selected  two  schemes.  In
addition,  the  main  constraints  that  hindered  the  development  of  irrigation  are  planning,
institutional,  social  and  operational  and  economic  problems  were  also  addressed.  This  is
needed  to  serves  for  different  purposes  such  as  for  the  construction  of  the  new  diversion
structures  (either  as  replacing  for  existing  structures  from  minor  repair  to  complete  reengineering  either  to  maintain  existing  function  or  to  meet  new  requirement).  The  field
survey has been made for these selected schemes to understand the current conditions of the
schemes. The observation indicated which structures were seriously damaged. The different
data’s were collected and used to analyze the main causes of failures of these two schemes.
The main problems observed in Kecha SSI scheme were sedimentation of the head work,
damage  of  intakes  and  sluice  gates,  clogging  of  intakes,  damages  of  distribution  systems
(pipes) and the  ram body. Whereas, the main problems observed in Awushoana SSI scheme
were accumulation of boulders, collapse of diversion weir, damages of the intake gates, main
canals and absence of the under sluice. Some of the problems attributed to the institutional,
social  and  operational  problems  are  lack  of  adequate  community  participation  in  planning
and designing, absence of WUAs, proper handing over problem and lack of proper training
and  absence  of  proper  maintenance,  evaluation  and  monitoring  issues.  Another  problem
observed on Awushoana diversion weir was improper hydrologic analysis which in turn the
problem  of  design  of  hydraulic  structures.  Therefore,  peak  discharge  was  estimated  to  be
122.66m
3
/s by using USSCS method  using the daily annual maximum rainfall of 31 years of
Hossaina  meteorological  station  which  is  near  to  the  project  site.  For  this  reason  proper
designing of the systems and increasing irrigation development activities based on  farmers’
awareness creation makes the schemes more functional and sustainable.

description: Spatial and temporal rainfall variability and unsustainable land use practices have always
been  major  hindrances  in  Ethiopian  agriculture.  Proper  land  evaluation  for  irrigated
agriculture  is  very  important  to  combat  such  problems.  This  study  was  conducted  to
assess irrigation potential in Guder river catchment, a sub basin of Abay river basin. The
study used FAO (1985)  guideline:  Land evaluation for irrigated agriculture. Five crops
(Maize,  wheat,  teff,  sorghum  and  Barley)  and  three  irrigation  methods  (surface,  center
pivot and portable sprinkler irrigation methods)  were selected as land utilization types.
Soil  properties,  land  slope,  land  cover  and  water  availability  were  evaluated  against
requirements  of  each  land  utilization  types.  Crop  water  demand  was  estimated  using
Penman-Monteith  and  Hargreaves  methods.  Surface  water  potentials  of  45  sub
watersheds of Guder river catchment were assessed using SCS-CN method.    The results
show  that  54,800ha,  112,000ha  and  442,000ha  of  land  are  marginally  suitable
(provisionally irrigable area) for  both  maize  and sorghum under three selected irrigation
methods (surface, center pivot and portable sprinkler irrigation systems) respectively. The
result  for  teff  is  56,300ha,  116,200ha  and  247,200ha  under  surface,  center  pivot  and
portable  sprinkler  irrigation  systems  respectively.  Whereas  59,500ha,  128300ha  and
283,300ha  of  land  is  marginally  suitable  for  wheat  crop  and  59,500ha,  125,500ha  and
283,300ha of land is marginally suitable for barley crop under surface, center pivot and
portable sprinkler irrigation systems respectively.  Major suitability  limitation was found
to  be  land  slope.  Results  of  surface  water  potential  analysis  showed  that  without
considering any artificial water storage structures, surface water potential of Guder river
catchment  can  support  9423  and  15070ha  of  land  for  surface  and  sprinkler  irrigation
systems respectively.  When storage structures are considered surface water potential of
the  study  area  can  accommodate  532,622  and  798,934ha  of  land  under  surface  and
sprinkler irrigation systems.

description: Library professionals with data responsibilities often collaborate on data-related support with fellow library professionals, units across campus, and student and faculty researchers. It is through these collaborations and partnerships that libraries can leverage the infrastructure and diverse skill sets needed to build effective and successful data-related support for the campus community. Yet, how these partnerships form and the shapes they take, particularly within the library, varies.

In this panel, we share strategies for collaborations between data professionals and subject and technical services librarians designed to enhance library and campus support for data literacy, data management, data visualization, and other data-related needs. The panelists present several strategies that focus on the reciprocal nature of building relationships, teaching/learning new technologies, and sharing expertise within the library. With each strategy, the panelists share their experience implementing it and highlight how successful collaborations resulted in broader impact and increased exposure of the library.

statistically  and  also  lan  use  and  land  cover  change  of  two  distnict  period  classification  were
analyzed by Ar-GIS for the pre and post dam period.  The Indicators of Hydrological alteration
soft ware were used to quantify the total flow of Gilgle Gibe I watersh ed at dam site. And we get
the significant effect of  climatic  variability for pre-dam construction in this study  area    the  data
such  precipitation,  temperature  and evapotranspiration  were used  to  analyze the    trend over the
range of 1988–2010  at    annual  timescale.  Change to rainfall trends of the  Asendabo and Limmu
station  shows  the  decreasing  trend  where  the  temperature  and  Evaporation  of  the  two  stations
shown  the increasing trend  which contributed to decrease the stream flow change in watershed  but
this  was statistically insignificant.  We also simulate and calibrate the Simhyd conceptual model
for  pre  and  post  dam  construction  and  the  result  show  the  were  the  significant  anthropogenic
impact on the streamflow during the post dam.    LULC change was  examined  for two distinct
periods of the 2000 and 2010 using Arc GIS10.1. This trend was not reflected in climatologically
drivers such as rainfall, evaporation and temperature (which shows a positive trend), but rather is
attributed to the substantial changes in  land  use and land cover in the watershed.  The significant
shift from forest and woodland to grassland,    cropland  and water body    results in a decrease of
actual  evaporation  and  subsequent  increase  in  (dry  season)  runoff.  We  used  the  ‘Range  of
Variability Approach’  to  quantify  hydrological alteration at  Gigle  gibeI Dam site.  The analysis
shows  that  the  five  groups  of  hydrological  characteristics  natural  flow  regime  using  the  IHA
(magnitude, timing, duration, frequency  and variability), only those related to  magnitude were
found to show significant trends, with the main trend being the increase of flow during the dry
season.

description: Abstract One of the performance levels of residential buildings is to avoid the global collapse of the building against maximum ground excitations. However, some common regulations for designing such structures, especially those that design such structures with force approaches instead of performance ones, do not require structural control at this level. Due to such issues, the need to increase the rigidity of the structure to control the performance levels mentioned in the structure is considered necessary. In this study, using the analytical approach, through incremental dynamic analysis, the nonlinear behavior of 4 moment frames in both intermediate and special ductility is estimated, then using fragility curves corresponding to the levels of collapse performance, fragility curves are plotted. Then, using the empirical approach and considering the difference in hardness of the four frames according to their pushover curve, the median and deviation changes from the criterion of nonlinear analysis response criteria, for each difficulty, are plotted. In the next step, for 6 different sites in terms of geotechnical and seismicity, probabilistic evaluation was performed to identify sites that have a higher probability of collapse than the acceptable level for these frames. For collapsible frames, the stiffness changes required to reduce the probability of structural collapse to an acceptable extent have been calculated according to the obtained curves. The results show that in the northern and southern constructions of Tehran, short rise intermaediate moment frames to provide protection against the possibility of collapse against maximum ground excitations should provide an increase in earthquake hardness of about 35% through permitted methods.

description: Assessing available land and water resources for irrigation is important for planning their
use. This study is initiated with the objective of assessing the water and land resources
potential of river catchments in Segen sub-basin for irrigation development
by using Geographic Information System(GIS).
The Segen sub-basin was selected as a case study for this thesis work which is located at the
Southern part of the Rift Valley River Basin covering an area of about 20,517 km
2
.
The evaluation of land in terms of the suitability classes for surface irrigation is based on the
method as described in FAO guideline for land evaluation. The essence of land evaluation for
irrigation is to compare or match the physical resource of soil, water, topography and others
with the irrigation requirement. A land unit is obtained by the overlaying of selected theme
layers, which has unique information of land qualities for which the suitability is based on.
The selected theme layers for this study include soil types, with their corresponding physical
and  chemical characteristics  that  affect  irrigation  agriculture,  land  cover,  and  slope  layer,
which is derived from the Digital Elevation Model of the study area. As its being the most
limiting factor for the realization of, especially for surface irrigation method, the slope layer
was used as the base map for the overlaying analysis.
The suitable land identified categorized according to the different climatic zones along the
Weito and Segen River in the sub-basin. They are mostly concentrated in the South central
and North Eastern part of the sub-basin. The 95, 90, 85, and 80 percentage time exceedance
flow  of  the  available  surface  water in  the  respective  climatic  zones  was  estimated  and  the
area that can be irrigated with this flow was computed using the sel ected climatic station data
and estimated ETo. When these factors were weighted using weighted overlay in Arc GIS,
the potential irrigable land for surface irrigation was reduced to 43,191ha.

Dynamics of telomere length and mitochondrial health in relation to combination antiretroviral therapy (cART) exposure : a cohort study of HIV/cART-exposed uninfected children and cell culture investigations
Creators: name: Ajaykumar, Abhinav

description: Combination antiretroviral therapy (cART) during pregnancy has considerably reduced the risk of mother-to-child HIV transmission and the number of cART-exposed HIV-exposed uninfected (HEU) children is increasing. With current treatment guidelines recommending the initiation of immediate, lifelong cART at HIV diagnosis, women conceive on therapy and HEU in utero cART exposure spans the entire gestation period. Many antiretrovirals (ARV) cross the placenta and could exert long-term effects on HEUs. Some ARVs inhibit human telomerase reverse transcriptase (hTERT). As hTERT elongates telomeres and protects mitochondrial DNA (mtDNA) from oxidative damage, its inhibition could lead to shorter telomeres and/or increased mitochondrial dysfunction. Leukocyte telomere length (LTL) and mtDNA alterations are biomarkers of cellular aging, and have been implicated in aging and age-related diseases. The objective of my research was to compare HEU and HIV-unexposed uninfected (HUU) children at birth and in early life, with respect to their LTL and blood mtDNA content, and investigate relationships with in utero cART exposure. I measured LTL and blood mtDNA content in 324 HEU and 306 HUU children between 0-3y of age. I found that exposure to maternal cART did not affect LTL at birth, as it was similar in both groups. However, mtDNA content was higher among HEU children, particularly those exposed to boosted-protease inhibitor (PI/r) cART. This increase in mtDNA persisted at least up to age three. Additionally, maternal smoking during pregnancy affected both LTL and mtDNA content at birth. Given these effects of cART on children’s mtDNA, I aimed to further characterize how various cART regimens affect mitochondrial health using an in vitro human cell culture model. I also investigated the potential mitochondrial protection conferred by hTERT. I found that dolutegravir (DTG)-containing regimens negatively affected mitochondria, decreased cell proliferation and increased apoptosis. PI/r-containing regimens also affected certain mitochondrial parameters, but this effect was mitigated by mitochondrial hTERT while that of DTG was not. DTG is increasingly used worldwide, including in pregnancy. These novel findings merit further investigations to evaluate the long-term safety of newer ARV exposure, and the predictive value of these biomarkers on HEU health outcomes. Together, this knowledge could inform treatment guidelines.
