description: We prove that given a stress-free elastic body there exists, for sufficiently small values of the gravitational constant, a unique static solution of the Einstein equations coupled to the equations of relativistic elasticity. The solution constructed is a small deformation of the relaxed configuration. This result yields the first proof of existence of static solutions of the Einstein equations without symmetries.

An introduction to the fermionic matrix model
Creators: name: Marshall, Nicole
Publisher: name: University of British Columbia
Year: 2009

description: Matrix models represent statistical theories of discrete random surfaces, and thus to some extent are relevant to the discrete surface interpretations of field theories such as 2D quantum gravity, string theory, lattice gauge theory, and QCD. Hermitian matrix models, in particular, have been extensively studied in connection with continuum field theories. Although these models exhibit inspiring and suggestive features, they are not without limitations, i.-e. the c = 1 barrier and a non-Borel summable free energy expansion. Hence, we introduce an extension to the theory of matrix models, a variation on the theme — the fermionic matrix model. In this work we make a preliminary study of the simplest fermionic matrix models using the insights and experience garnered from the study of the Hermitian matrix model. Our primary resource is the Makeenko-Migdal method of loop equations from which we find that the fermionic 1-matrix model possesses some unique and promising features including a first order multi-critical point and an alternating free energy expansion.. Non-trivial higher dimensional models subject to modified but consistent loop equation techniques prove immune to analysis by these methods alone.

description: Malaria remains a health problem, its control based on killing female of Anopheles mosquitoes with an insecticide is threatened by spread of insecticide resistance. Male of Anopheles mosquitoes, meet in the evening at sunset and form what called “swarm” with huge number of male in stable location. We investigated how trapping mosquitoes at the swarming time might reduce their numbers and be used as a community-based-approach for reducing malaria transmission. In 2017, we recorded information on behavior of swarms of Anopheles mosquitoes, number of female mosquitoes and number of mosquitoes and humans infected with malaria in six villages in eastern Gambia. During the 2018 malaria transmission season, swarms were collected twice per week from previously identified locations and the mosquitoes killed.Twenty-three swarming sites close to human habitats were identified and collected 36,327 Anopheles males from them during the 5-month. Our preliminary results suggest that the intervention resulted in a 90% reduction in mosquito numbers, from 53 Anopheles mosquitoes per house to 3.5. Whether the intervention reduced the incidence of malaria is now being tested. If catching mosquitoes have been successful in reducing malaria in this study, a larger trial will be needed before considering this intervention as a possible tool for malaria control.

description: The unbound proton-rich nuclei $^{16}$F and $^{15}$F are investigated experimentally and theoretically. Several experiments using the resonant elastic scattering method were performed at GANIL with radioactive beams to determine the properties of the low lying states of these nuclei. Strong asymmetry between $^{16}$F-$^{16}$N and $^{15}$F-$^{15}$C mirror nuclei is observed. The strength of the $nucleon-nucleon$ effective interaction involving the loosely bound proton in the $s_{1/2}$ orbit is significantly modified with respect to their mirror nuclei $^{16}$N and $^{15}$C. The reduction of the effective interaction is estimated by calculating the interaction energies with a schematic zero-range force. It is found that, after correcting for the effects due to changes in the radial distribution of the single-particle wave functions, the mirror symmetry of the $n-p$ interaction is preserved between $^{16}$F and $^{16}$N, while a difference of 63\% is measured between the $p-p$ versus $n-n$ interactions in the second excited state of $^{15}$F and $^{15}$C nuclei. Several explanations are proposed.

description: Objective
We examined the association between survival of insecticides and mosquitoes resting inside homes (indoor) and outside houses (outdoor) in two communities in Northern Ghana.

Methods
We collected live adult mosquitoes indoors and outdoors from the two communities. We generated offspring from a subset of mosquitoes and exposed them to four insecticides using methods recommended by WHO. We subsequently evaluated the heritable factors responsible for survival of insecticides in the two mosquito groups.

Results
Survival to two insecticides - DDT and deltamethrin were substantially high in both mosquitoes resting indoors and outdoors. This was very different between the two groups. Only few mosquitoes survived bendiocarb while almost all indoor and outdoor mosquitoes could not survive malathion. We did not observe large differences in survival of the two mosquito populations to both bendiocarb and malathion insecticides.

Furthermore, we identified certain heritable factors responsible for survival to DDT and deltamethrin in the two mosquito groups and these differed significantly between the mosquito groups.

Conclusions
Our work showed that mosquitoes resting indoors and outdoors are displaying different survival ability to the insecticides for malaria control at the study sites. This shows that resting behavior of mosquitoes can threaten the effectiveness of insecticides for malaria control and should be actively monitored.

Publisher: name: AAS Open Research
Year: 2019

description: Objectives: Caregivers of children with life-long disabilities such as cerebral palsy (CP) are at risk of poor health outcomes because of the excessive demands of the caregiving role. Unique factors such as societal stigma and poverty further predispose caregivers from low-income countries to poor mental health. However, caregivers who receive an adequate amount of social support adjust to the caregiving role better. The present study evaluated the mental health of Zimbabwean caregivers of children with CP.
Methods: Data were collected from 1 232 caregivers using a cross-sectional study. Study outcomes included levels of; social support, health-related quality of life (HRQoL), caregiver burden, and common mental disorders. Data were analysed using quantitative statistics.
Results: Most caregivers were mothers to the children (96%), married (91%), educated (97%) and unemployed (75%). 47% of caregivers of children with CP exhibited common mental disorders. Further, most caregivers reported of; high caregiver burden, and lower HRQoL when compared to caregivers of typically developing children. However, caregivers receiving adequate social support had optimal mental health. Child factors (e.g. severe disability) and caregiver factors (e.g. lower income status) were associated with poor mental health.
Conclusions: There is a need to; routinely monitor the mental health of caregivers, and develop and implement caregiver well-being interventions.

Lorentz-violating dilatations in the momentum space and some extensions on non-linear actions of Lorentz algebra-preserving systems

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We work on some general extensions of the formalism for theories which preserve the relativity of inertial frames with a nonlinear action of the Lorentz transformations on momentum space. Relativistic particle models invariant under the corresponding deformed symmetries are presented with particular emphasis on deformed dilatation transformations. The algebraic transformations relating the deformed symmetries with the usual (undeformed) ones are provided in order to preserve the Lorentz algebra. Two distinct cases are considered: a deformed dilatation transformation with a spacelike preferred direction and a very special relativity embedding with a lightlike preferred direction. In both analysis we consider the possibility of introducing quantum deformations of the corresponding symmetries such that the spacetime coordinates can be reconstructed and the particular form of the real space-momentum commutator remains covariant. Eventually feasible experiments, for which Lorentz violating effects here pointed out may be detectable, are suggested.

description: The operation of multiple systems is not stable. This issue is treated using a new system consisting of a compensator and a unit feedback. The closed loop system is with inner stability, and the system outputs have desirable behaviour. No undesirable reactions/interrelations between input and output are observed. The main objective is to develop two Matlab programs, using the GUI environment, able to estimate the compensator of a closed loop system. The transfer function of the open loop system is estimated in the first program named “compensatorabcd”. This system receives an input, assuming the matrices of an automated control system to be known. These matrices are connected using the functions in the device area. The transfer function is further estimated using a compensator. The desired poles are inserted a priori. The transfer function of an open loop is inserted in the second program named “compensator”, aiming to estimate the transfer function of a closed loop and a compensator. The current study consists of two chapters. The theory and literature review is mentioned in the first chapter. The programs and their manuals are presented in the second chapter.

description: Most countries of the Arab Mashrek are multi-ethnic and multi-sectarian. In recent years, most of them have experienced violent clashes between groups that frame their conflicts along ethnic-sectarian lines. This article investigates the Lebanese Ta’if Agreement of 1989 as a crucial case study of how to manage such conflicts through a transitory power-sharing arrangement. It presents several provisions of this agreement that adhere to three different approaches of how to deal with such conflicts: the consociational and the centripetal models of power-sharing as well as the integrationist paradigm. It thereby seeks to develop a theoretical argument about chances and risks of transitory power-sharing in deeply divided societies and derives some general lessons for managing conflicts in the Middle East.
Surrender? What surrender? : Yan Xishan’s reconsolidation of power in Taiyuan July - August, 1945
Creators: name: Mitchell, James Alexander
Publisher: name: University of British Columbia
Year: 2009

description: In August 1945 North China found itself in a situation where 'defeated' Japanese troops were in possession of territory which was contested by several 'victors', including both rival Chinese and foreign military forces. Not only did this complicate the process of surrender, but it provided the opportunity and conditions for the resumption of civil war. The placement of Japanese troops in places throughout the country put them in a good position to counter CCP advances until such time that GMD troops could arrive to take the surrender. In Shanxi, warlord governor Yan Xishan - Jiang Jieshi's commander of the 2nd War Zone - had been living in quasi-exile in southwestern Shanxi. He took this formula one step further by negotiating a set of conditions, some of which had been in place before the surrender, under which the Japanese would 'surrender' only to his own troops, and in fact to join him to fight against the communists who surrounded the cities and rail lines. During the summer of 1945, in anticipation of surrender, Yan moved closer to Taiyuan, the capital, and began to negotiate his return there with the local Japanese commander, along with formal acceptance of the surrender. When the war ended, he was already moving his armies and himself toward the major cities, especially the Fen River basin around Taiyuan. The 8th Route Army in Shanxi held the majority of the province, for its own part, but their guerrilla strategy kept them away from the cities until after the surrender. Yan's familiarity with the Japanese allowed him a measure of flexibility throughout the war which facilitated collaboration. By 1945 a virtual ceasefire existed between them, and Yan moved his troops easily through their lines to attack the communists. In addition, both Yan and General Sumita in Taiyuan recognized that without each other they both faced certain defeat, and began preparing for the surrender in Shanxi. Power was to be transferred under this scheme to Yan alone. When the end of the war did come, then, Yan shuttled toward Taiyuan where, on August 30, he arrived by armoured car, protected by his own and Japanese troops. With Japanese soldiers still in positions along the rail lines and in many towns, He was not only able to protect himself as he returned to Taiyuan, but denied the communists the opportunity to expand from the countryside. There presently exists very little in English on this topic. Recent source material in Chinese, however, has made it possible to look in detail into the circumstances of these events, and confirms that the surrender in August 1945 represented neither the end of war nor the end of Japanese intervention in China.
Lagrangian study of dispersion and transport by submesoscale currents at an upper-ocean front

description: The three-dimensional transport pathways, the time scales of vertical transport, and the dispersion characteristics of submesoscale currents at an upper-ocean front are investigated using material points (tracer particles) that advect with the local fluid velocity. Coherent submesoscale vortex filaments and eddies which dominate submesoscale (0.1 - 10 km) dynamics are found to play a crucial role which is quantified here. These coherent structures are generated and sustained through nonlinear evolution of baroclinic instability. The collective motion of particles helps identify common features of transport at the front. It is found that the particles in the central region organize into inclined lobes, each associated with an eddy, and the filaments associated with the heavy- and light-edges of the front transfer edge particles to the lobes. This flux of new particles into the lobe causes local particles to adjust, which leads to slumping of the front. The particle motion in the vertical shows multiple time scales -- a fast time scale with O(10) m vertical displacement within an hour and a slower near-inertial time scale, comparable to the intrinsic time scale of the growing instability. The fast time scale motions typically occur in the vortex filaments. The overall slumping process is slower than what one might anticipate from the large magnitude of vertical velocity in the filaments and requires a sustained correlation over time between the lateral and the vertical motion. By tracking clouds of particles, we show that their centers of mass downwell/upwell over 1-2 inertial time periods, after which an adjustment follows with a sub-inertial time scale. The dispersion characteristics of the submesoscale turbulent currents using single- and pair-particle statistics have been investigated. The shape change in clusters of four particles reveals deformation into thin, needle-like structures.

description: We present new spectroscopic metal abundances for 74 RR Lyrae stars in omega Cen obtained with FLAMES. The well-known metallicity spread is visible among the RR Lyrae variables. The metal-intermediate (MInt) RR Lyrae stars ([Fe/H] ~ -1.2) are fainter than the bulk of the dominant metal-poor population ([Fe/H] ~ -1.7), in good agreement with the corresponding zero-age horizontal branch models with cosmological helium abundance Y = 0.246. This result conflicts with the hypothesis that the progenitors of the MInt RR Lyrae stars correspond to the anomalous blue main-sequence stars, which share a similar metallicity but whose properties are currently explained by assuming for them a large helium enhancement. Therefore, in this scenario, the coexistence within the cluster of two different populations with similar metallicities ([Fe/H] ~ -1.2) and different helium abundances has to be considered.

description: We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous conductance signatures in single-walled carbon nanotube (SWCNT) quantum dots can be understood quantitatively in terms of current driven `hot phonons' that are strongly correlated with electrons. Using rate equations in the many-body configuration space for the joint electron-phonon distribution, we argue that the variations are indicative of strong electron-phonon coupling requiring an analysis beyond the traditional uncorrelated phonon-assisted transport (Tien-Gordon) approach.

Micropollutant degradation, bacterial inactivation and regrowth risk in wastewater effluents: influence of the secondary (pre)treatment on the efficiency of Advanced Oxidation Processes

description: Pre-proof version In this work, disinfection by 5 Advanced Oxidation Processes was preceded by 3 different secondary treatment systems present in the wastewater treatment plant of Vidy, Lausanne (Switzerland). 5 AOPs after two biological treatment methods (conventional activated sludge and moving bed bioreactor) and a physiochemical process (coagulation-flocculation) were tested in laboratory scale. The dependence among AOPs efficiency and secondary (pre)treatment was estimated by following the bacterial concentration i) before secondary treatment, ii) after the different secondary treatment methods and iii) after the various AOPs. Disinfection and post-treatment bacterial regrowth were the evaluation indicators. The order of efficiency was Moving Bed Bioreactor > Activated Sludge > Coagulation-Flocculation > Primary Treatment. As far as the different AOPs are concerned, the disinfection kinetics were: UVC/H2O2 > UVC and solar photo-Fenton > Fenton or solar light. The contextualization and parallel study of microorganisms with the micropollutants of the effluents revealed that higher exposure times were necessary for complete degradation compared to microorganisms for the UV-based processes and inversed for the Fenton-related ones. Nevertheless, in the Fenton-related systems, the nominal 80% removal of micropollutants deriving from the Swiss legislation, often took place before the elimination of bacterial regrowth risk.

description: The sensitivity and angular resolution of photometric surveys executed by the Hubble Space Telescope (HST) enable studies of individual star clusters in galaxies out to a few tens of megaparsecs. The fitting of spectral energy distributions (SEDs) of star clusters is essential for measuring their physical properties and studying their evolution. We report on the use of the publicly available Code Investigating GALaxy Emission (CIGALE) SED fitting package to derive ages, stellar masses, and reddenings for star clusters identified in the Physics at High Angular resolution in Nearby GalaxieS-HST (PHANGS-HST) survey. Using samples of star clusters in the galaxy NGC 3351, we present results of benchmark analyses performed to validate the code and a comparison to SED fitting results from the Legacy ExtraGalactic Ultraviolet Survey (LEGUS). We consider procedures for the PHANGS-HST SED fitting pipeline, e.g., the choice of single stellar population models, the treatment of nebular emission and dust, and the use of fluxes versus magnitudes for the SED fitting. We report on the properties of clusters in NGC 3351 and find, on average, the clusters residing in the inner star-forming ring of NGC 3351 are young ($< 10$ Myr) and massive ($10^{5} M_{\odot}$) while clusters in the stellar bulge are significantly older. Cluster mass function fits yield $β$ values around -2, consistent with prior results with a tendency to be shallower at the youngest ages. Finally, we explore a Bayesian analysis with additional physically-motivated priors for the distribution of ages and masses and analyze the resulting cluster distributions.

description: We report an experimental study of miniband magnetoconduction in semiconducting InAs/GaSb superlattices. For samples with miniband widths below the longitudinal optical phonon energy we identify a new superlattice magnetophonon resonance (SLMPR) caused by resonant scattering of electrons across the mini-Brillouin zone. This new resonant feature arises directly from the drift velocity characteristics of the superlattice dispersion and total magnetic quantisation of the superlattice Landau level minibands.

description: Electron fractionalization is intimately related to topology. In one-dimensional systems, fractionally charged states exist at domain walls between degenerate vacua. In two-dimensional systems, fractionalization exists in quantum Hall fluids, where time-reversal symmetry is broken by a large external magnetic field. Recently, there has been a tremendous effort in the search for examples of fractionalization in two-dimensional systems with time-reversal symmetry. In this letter, we show that fractionally charged topological excitations exist on graphenelike structures, where quasiparticles are described by two flavors of Dirac fermions and time-reversal symmetry is respected. The topological zero-modes are mathematically similar to fractional vortices in p-wave superconductors. They correspond to a twist in the phase in the mass of the Dirac fermions, akin to cosmic strings in particle physics.

description: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data sets jointly gave tentative evidence for a hard X-ray periodicity, with a period of $\sim 9$ s and a period increase rate by $\sim 3 \times 10^{-10}$ s s$^{-1}$. Therefore, the compact object in LS 5039 is inferred to be a rotating neutron star, rather than a black hole. Furthermore, several lines of arguments suggest that this object has a magnetic field of several times $\sim 10^{10}$ T, two orders of magnitude higher than those of typical neutron stars. The object is hence suggested to be a magnetar, which would be the first to be found in a binary. The results also suggest that the highly efficient particle acceleration process, known to be operating in LS 5039, emerges through interactions between dense stellar winds from the massive primary star, and ultra-strong magnetic fields of the magnetar.

description: By studying classes of supersymmetric solutions of D=11 supergravity with AdS_5 factors, we determine some properties of the dual four-dimensional N=1 superconformal field theories. For some explicit solutions we calculate the central charges and also the conformal dimensions of certain chiral primary operators arising from wrapped membranes. For the most general class of solutions we show that there is a consistent Kaluza-Klein truncation to minimal D=5 gauged supergravity. This latter result allows us to study some aspects of the dual strongly coupled thermal plasma with a non-zero R-charge chemical potential and, in particular, we show that the ratio of the shear viscosity to the entropy density has the universal value of 1/4 pi.

Castles fall from inside: Evidence for dominant internal photo-catalytic mechanisms during treatment of Saccharomyces cerevisiae by photo-Fenton at near-neutral pH

description: Pre-proof versionIn this work, the antimicrobial effects of the photo-Fenton process on yeast cells were tested (Saccharomyces cerevisiae), an essential eukaryotic unicellular model of living cells. Near-neutral pH was used in all studies, while iron sulfate and iron citrate were evaluated as iron sources during S. cerevisiae photo-Fenton inactivation under simulated solar light (hv/H2O2/Fe). The following indicators were monitored to decrypt the mechanism of yeast inactivation by neutral photo-Fenton process: cell viability by flow cytometry, damage at DNA level, as well as intracellular and extracellular proteins, assessed by gel electrophoresis. A significant loss of cultivability was monitored through the application of all the different photo-Fenton systems, attributed to the oxidative stresses applied. The mechanisms involved were the homogeneous action of dissolved iron and the heterogeneous action mode of iron oxides. The DNA and protein analyses indicated drastic intracellular damages, while external macromolecules (cell wall and membrane proteins) showed limited degradation. This marked internal photocatalytic processes as the main inactivation mechanism in S. cerevisiae. Different pathways are proposed, forming a general process of inactivation by the near-neutral photo-Fenton systems.
Classifying Hilbert functions of fat point subschemes in $\mathbb P^2$

description: A recent paper by the first and third authors together with Sabourin raised the question of what the possible Hilbert functions are for fat point subschemes of the form $2p_1+...+2p_r$, for all possible choices of $r$ distinct points in the projective plane. We study this problem for $r$ points in the plane over an algebraically closed field $k$ of arbitrary characteristic in case either $r \le 8$ or the points lie on a (possibly reducible) conic. In either case, it follows from work of the second author that there are only finitely many configuration types of points, where our notion of configuration type is a generalization of the notion of a representable combinatorial geometry, also known as a representable simple matroid. (We say $p_1,...,p_r$ and $p'_1,...,p'_r$ have the same {\it configuration type} if for all choices of nonnegative integers $m_i$, $Z=m_1p_1+...+m_rp_r$ and $Z'=m_1p'_1+...+m_rp'_r$ have the same Hilbert function.) Assuming either that $7 \le r\le 8$ (see recent work of Guardo and the second author for the cases $r\le 6$) or that the points $p_i$ lie on a conic, we explicitly determine all the configuration types, and show how the configuration type and the coefficients $m_i$ determine (in an explicitly computable way) the Hilbert function (and sometimes the graded Betti numbers) of $Z=m_1p_1+...+m_rp_r$. We demonstrate our results by explicitly listing all Hilbert functions for schemes of $r\le 8$ double points, and for each Hilbert function we state precisely how the points must be arranged (in terms of the configuration type) to obtain that Hilbert function.

Right-handed Sneutrinos as Nonthermal Dark Matter

description: When the minimal supersymmetric standard model is augmented by three right-handed neutrino superfields, one generically predicts that the neutrinos acquire Majorana masses. We postulate that all supersymmetry (SUSY) breaking masses as well as the Majorana masses of the right-handed neutrinos are around the electroweak scale and, motivated by the smallness of neutrino masses, assume that the lightest supersymmetric particle (LSP) is an almost-pure right-handed sneutrino. We discuss the conditions under which this LSP is a successful dark matter candidate. In general, such an LSP has to be nonthermal in order not to overclose the universe, and we find the conditions under which this is indeed the case by comparing the Hubble expansion rate with the rates of the relevant thermalizing processes, including self-annihilation and co-annihilation with other SUSY and standard model particles.

description: Objectives : The study aimed to analyze the degree of intra and intersectoral collaborations in the national program for the management of neglected tropical diseases (NTDs) in Côte d'Ivoire. It further identifies barriers to an improved integration, more particularly with Water, Sanitation and Hygiene programs (WASH).
Methods :The evaluation of these collaborations, guided by the theory of stakeholder analysis, was carried out following individual semi-structured interviews or focus group with key stakeholders.
Results and conclusions : Despite the massive presence of institutional actors involved in the control, Côte d’Ivoire is still endemic to nine neglected tropical diseases (NTDs). Prevention and control consists of mass drug administration (MDA) compaign, case management. This study highlighted the modest beginnings of intra and intersectoral collaborations for public management of the NTDs in Côte d’Ivoire. However, these collaborations are strongly influenced by a biomedical approach and not by a Ecohealth encompassing the ecosystem dimensions. This is characterized by the failure to take into account, in control strategies, the environmental risk factors (water, season) and management enabling or disabling factors (sanitation, hygiene). The integration of environmental factors of NTDs through access to clean water, sanitation, hygiene and behavior change can be associated to the chemotherapy strategy for effective control.

description: Capturing the 'mutual gaze' of people is essential for understanding and interpreting the social interactions between them. To this end, this paper addresses the problem of detecting people Looking At Each Other (LAEO) in video sequences. For this purpose, we propose LAEO-Net++, a new deep CNN for determining LAEO in videos. In contrast to previous works, LAEO-Net++ takes spatio-temporal tracks as input and reasons about the whole track. It consists of three branches, one for each character's tracked head and one for their relative position. Moreover, we introduce two new LAEO datasets: UCO-LAEO and AVA-LAEO. A thorough experimental evaluation demonstrates the ability of LAEO-Net++ to successfully determine if two people are LAEO and the temporal window where it happens. Our model achieves state-of-the-art results on the existing TVHID-LAEO video dataset, significantly outperforming previous approaches. Finally, we apply LAEO-Net++ to a social network, where we automatically infer the social relationship between pairs of people based on the frequency and duration that they LAEO, and show that LAEO can be a useful tool for guided search of human interactions in videos. The code is available at https://github.com/AVAuco/laeonetplus.

Publisher: name: AAS Open Research
Year: 2019

description: Objectives
Measures to control malaria and low blood haemoglobin levels (LBHL) of pregnant women in Ghana have improved yet they still have LBHL and small babies. Other infections like intestinal worms and schistosomiasis may be responsible although how much they contribute is unknown. This study is to determine how much malaria, intestinal worms and schistosomiasis each alone and together cause LBHL and small babies.

Methods
This study began in June, 2018 and is on-going. Pregnant women are being followed in antenatal clinics (ANC) in Ashanti and Volta Regions, Ghana, until 2500 live babies are born. Information about who the women are, their social and economic conditions, past pregnancies and illnesses is being gathered. Also blood, urine and stool tests are being done for haemoglobin blood levels, malaria, worms and schistosomiasis. Treatments received at ANC, any illnesses during pregnancy and their babies’ weight are being recorded.

Results
The women enrolled are 2461 with average age 27 years. Only 47% use bed nets although 61% have them. Approximately 50% and 7% have LBHL and malaria respectively at enrolment. Out of 419 babies born, 9.3% are small.
Conclusion
Although malaria appears low, maternal anaemia and small babies’ occurrence are high. These findings will be understood the end of the study.
