PYRENAIC ROCK GLACIERS: AN AIRBORNE AND MULTITEMPORAL LiDAR MONITORING CASE STUDY IN THE BESIBERRI AREA

The monitoring of rock glaciers is a current subject of interest because of its application as permafrost indicator and its sensitivity to climatic changes (especially temperature and precipitation). Alpine rock glaciers in the Pyrenees have been described by various authors, but to study them regionally has been a challenge since most of these studies are based on groundbased techniques. Two LiDAR campaigns (the first one completed in 2015 and the second one currently ongoing) performed by the Spanish Instituto Geográfico Nacional (IGN), up to now mainly used for land management purposes, present the perfect opportunity to combine both datasets and asses the movement of this periglacial features. The present work aims to show how by analysing two sets of open source LiDAR data (acquired in 2011 and 2016) and calculating elevation difference, the mapping of these features can be enhanced. The results will show how some recently proposed potentially active rock glaciers are showing vertical displacement and some other are not. Additionally, the displacement results of the Besiberri NW rock glacier are compared versus the results obtained by previous studies (1993-2003) by Chueca and Julian (2005) showing an increase on the vertical displacement of the central area interpreted as possible destabilization due to ice core ablation. To conclude, the climate monitoring implications, the limitations of the technique and further work to improve these results together with future applications are also discussed.
Frequency and diversity of trypanosomes in sheep and goats from Mongo County in South Gabon, Central Africa

Background and Aim: Trypanosomosis is a major impediment to livestock farming in sub-Saharan Africa. It is a vector-borne disease caused by several species of protozoan parasites, namely, trypanosomes. The present study aimed to identify the diversity of trypanosome species infecting sheep and goats from Mongo County and to determine the frequency of these parasites. Materials and Methods: This study was conducted on 286 trypanotolerant goats and sheep from Mongo regions located in South Gabon, using polymerase chain reaction. Results: Analyses showed that the overall occurrence of trypanosomosis in small ruminants was 13.6% (39/286). Our results also showed that two factors, species and season, could affect the occurrence rate of Trypanosoma. A total of six Trypanosoma species were identified, two in sheep (Trypanosoma simiae and Trypanosoma theileri) and five in goats (Trypanosoma vivax, T. simiae, T. simiae Tsavo, Trypanosoma congolense, and Trypanosoma brucei), though Trypanosoma simiae was the most important species. Mixed infections were also found in goats (54.5%) and sheep (3.57%). Conclusion: Our study demonstrated that small ruminants could represent a reservoir of biodiversity for Trypanosoma parasites.
Role of Chest X-Ray in Assessing Severity of Pneumonia in Children: A Study in Dhaka Shishu (Children) Hospital, Dhaka, Bangladesh

Original Research Article Introduction: Community acquired pneumonia (CAP) is defined clinically as presence of signs and symptoms of pneumonia in a previously healthy child due to an infection which has been acquired outside hospital. Pneumonia is the leading cause of death in children worldwide. Accurate assessment of severity and prognosis is important to decide management of pneumonia. Objective: The objective of present study is to study role of Chest X-ray in predicting severity of pneumonia in children. Material & Methods: This was prospective observational type, hospital based study conducted from March 2019 till June 2020 years in Dept. of Radiology & Imaging Pediatric ward of Dhaka Shishu (Children) Hospital, Dhaka, Bangladesh. A total of 307 children aged 3 months to 59 months diagnosed with Pneumonia & Severe pneumonia as per World Health Organization (WHO) criteria were included in study. Chest radiographs were reported by Pediatric Radiologist and findings classified as Normal, Primary End point consolidation, Other Infiltrates, Pleural effusion. Results were compared in sub-group i.e. Pneumonia & Severe Pneumonia. Results: Hypoxia, cyanosis, grunting and severe malnutrition were found to be poor predictors of radiographic pneumonia. Bilateral infiltrates (30%) & Primary end point consolidation on right side (17%) are independent determinant of severity of pneumonia. Bilateral consolidation and bilateral pleural effusion on chest X-ray are associated with poor outcome. Conclusion: Children with cyanosis, grunting, hypoxia & severe malnutrition should preferentially have chest X-ray done since they are more likely to have consolidation, infiltrates or pleural effusion. Children with Bilateral infiltrates, Consolidation and Bilateral pleural effusion should preferably be admitted to pediatric intensive care unit for more aggressive monitoring and management, since they have poor outcome.
An approach to prepare nanosized HZSM-22 with enhanced lifetime in the methanol to hydrocarbon (MTH) reaction

Nanosized HZSM-22 has been successfully prepared using ball milling combined with alkaline and acid leaching treatment. The samples were characterized by XRD, XRF, nitrogen physical adsorption–desorption, SEM and solid state NMR. The results showed that the size of the zeolite crystal was greatly reduced after ball milling treatment, and that the crystallinity of the milled sample can be almost totally restored after further alkaline and acid treatment. The prepared nanosized HZSM-22 exhibited enhanced catalytic stability compared with the parent sample in the MTH reaction. Detailed product analysis implied that the improvement of the diffusion effect and the correspondingly reduced secondary reaction would be the most important factor for the long-term MTH operation over the nanosized catalyst.
BIOLOGICAL TREATMENT OF CONTAMINATED WATER IN MINERAL ELEMENTS BY USING MIXING OF DODONAEA SP. AND ARUNDO SP. PLANTS

The present study was testing the two plants (Dodonaea sp. and Arundo sp.) for repairing some lab ecosystems through their ability of treating contaminated water with some pollutants metals that produced from some laboratory equipments and before throwing it to the wastewater drainage channels. Four treatments were prepared and tested (TA= Dodonaea 25% + Arundo 75%, TB= Dodonaea 50% + Arundo 50%, TC = Dodonaea 75% + Arundo 25% and C= contaminated water only that consider to be a control test. Both plants were exposed to heavy elements (Pb, Cd, Cu, Fe and Zn) for a period of thirty days and record the tolerance range twice weekly for both mixed plants, all data recorded was triplicate. Atomic absorption spectrometer used to estimated metals concentrations. The results show that mostly there are significant differences at each mineral concentration towards treatments during tested period. Aim of this work is to find a simple and friendly ways to limit the contamination in aqua ecosystem.
Surfactant-induced lyotropic behavior of flexible polymer solutions

A theoretical analysis is presented to describe the stiffening of flexible, linear polymer chains due to complexation with oligomeric surfactants. These surfactants might be functionalized protonic acids or possess other types of end groups that exhibit strong, specific interactions with the flexible polymer backbone. The enhancement of the persistence length due to steric interactions between the bound surfactant tails is considered and the possibility of lyotropic behavior at finite polymer concentration is investigated. The results are discussed in the context of recent experiments by Cao and Smith, who reported liquid crystallinity in solutions of polyaniline complexed with camphorsulfonic acid
Supplementing diets for broilers that are low in crude protein and amino acids with protease

The study evaluated supplementation of broiler diets with a protease enzyme. Six hundred Ross 308 female broiler chicks were acquired at one day of age and randomly distributed to three treatments with five replicates of 40 chicks each. The experimental treatements consisted of i) a positive control diet with normal levels of crude protein, digestible lysine and digestible sulphur containing amino acids (PC); ii) a negative diet with reduced levels of crude protein, digestible lysine and digestible sulphur containg amino acids (NC); and iii) the NC diet augmented with Ronozyme ProAct protease at 200 mg/kg (NC+ENZY). Compared to the other diets, feeding the PC produced the highest final bodyweight (BW), bodyweight gain (BWG), and feed intake (FI) and best feed conversion ratio (FCR) over 0 - 42 days. The PC diet also produced the highest hot and cold carcass yields, ileal protein digestibility and improved the serum biochemistry parameters. Relative to the NC, the NC+ENZY diet increased BW, BWG and FI, improved FCR, increased ileal protein digestibility, hot and cold carcass yields, and the crude protein content of meat. However, it decreased serum triglyceride and very low density lipoprotein (VLDL) cholesterol levels and the crude fat content of meat of broilers. As a result, protease supplementation at the level of 200 mg/kg may not remove the detrimental effects that are caused by a 6% reduction in crude protein and digestible amino acids on performance, hot and cold carcass yields and ileal digestibility of crude protein of broilers. Keywords: broiler, growth performance, low crude protein diet, meat, nutrient digestibility, protease, serum biochemistry parameters
KungFu: Making Training in Distributed Machine Learning Adaptive

When using distributed machine learning (ML) systems to train models on a cluster of worker machines, users must conﬁgure a large number of parameters: hyper-parameters (e.g. the batch size and the learning rate) affect model convergence; system parameters (e.g. the number of workers and their communication topology) impact training performance. In current systems, adapting such parameters during training is ill-supported. Users must set system parameters at deployment time, and provide ﬁxed adaptation schedules for hyper-parameters in the training program. We describe KungFu , a distributed ML library for TensorFlow that is designed to enable adaptive training. KungFu allows users to express high-level Adaptation Policies (APs) that describe how to change hyper- and system parameters during training. APs take real-time monitored metrics (e.g. signal-to-noise ratios and noise scale) as input and trigger control actions (e.g. cluster rescaling or synchronisation strategy updates). For execution, APs are translated into monitoring and control operators, which are embedded in the dataﬂow graph. APs exploit an efﬁcient asynchronous collective communication layer, which ensures concurrency and consistency of monitoring and adaptation operations.
Global model and diagnostic of a low-pressure SF6/Ar inductively coupled plasma

A global model has been developed for low-pressure (3–20 mTorr), radio-frequency (rf) (13.56 MHz) inductively coupled plasmas (ICPs), produced in SF6/Ar mixtures. The model is based on a set of mass balance equations for all the species considered, coupled to the discharge power balance equation and the charge neutrality condition. Simulations are used to show the impact of operating conditions, such as the rf power, the pressure and the percentage of argon in the mixture, on the evolution of charged and neutral species. Langmuir probe and optical emission spectroscopy measurements are used to determine the electron temperature and the densities of electrons, ions and atomic fluorine in the SF6/Ar ICPs under study. These data are compared with simulation results obtained from the global model. A satisfactory agreement is found between the simulation results and the measured values of the electron density and temperature, for rf powers in the range 900–1700 W, regardless of the percentage of argon in the mixture. Predictions for the atomic fluorine density (∼1014 cm−3) are in good agreement with experiment, for various rf powers.
Chemical, Anti-Nutritional and Sensory Attributes of Melon Enriched Gari

This study was carried out to determine the chemical, anti-nutritional and sensory quality attributes of melon enriched gari. Freshly harvested cassava was peeled, washed and grated into pulp. Cassava pulp and melon flour were mixed together in ratio 90:10 and 80:20 respectively. The fermented mixture was packaged in a sack and fermented for five days. The fermented mixture was dewatered and samples taken each day, pulverized and toasted. Proximate, mineral, anti-nutritional factors and sensory quality attributes of the gari were determined. Protein content ranged from 0.838. 86 % in the gari with 20% melon. Fat and crude fibre increased with melon substitution. Carbohydrate contents of the control were higher than melon substituted gari. The pH ranged from 5.5 in control day 5 to 6.6 in enriched gari at 20 % level. Higher potassium and sodium were observed in the control gari while the melon substituted gari had higher values in the calcium, magnesium and phosphorus. Oxalate, tannin and hydrogen cyanide contents ranged from 0.27-1.35 mg/g, 0.24-0.69 mg/g and 0.05-0.18 mg/g respectively in the gari. Sensory evaluation conducted showed no significant differences (p<0.05) in the texture of the control gari from day one to five but there were significant differences (p>0.05) in the texture, aroma and appearance of melon fortified gari. The longer the fermentation of gari fortified with melon, the better it becomes in term of the sensory quality attributes. Enrichment of gari with 10 % melon in day 3 to 5 was more acceptable in terms of texture, appearance and overall acceptability. The protein contents of gari increased with increase in the level of melon flour addition.
A Meta Learning Approach to Discerning Causal Graph Structure

We explore the usage of meta-learning to derive the causal direction between variables by optimizing over a measure of distribution simplicity. We incorporate a stochastic graph representation which includes latent variables and allows for more generalizability and graph structure expression. Our model is able to learn causal direction indicators for complex graph structures despite effects of latent confounders. Further, we explore robustness of our method with respect to violations of our distributional assumptions and data scarcity. Our model is particularly robust to modest data scarcity, but is less robust to distributional changes. By interpreting the model predictions as stochastic events, we propose a simple ensemble method classifier to reduce the outcome variability as an average of biased events. This methodology demonstrates ability to infer the existence as well as the direction of a causal relationship between data distributions.
Transformation of Akaganéite Into Goethite and Hematite in Alkaline Media

The conversion of akaganéite to goethite and/or hematite in alkaline media has been followed by X-ray powder diffraction and transmission electron microscopy (TEM). The rate of transformation fell and the amount of hematite in the product increased as the [OH−] decreased to < 1 M. Kinetic studies and TEM indicated that the transformation involved dissolution of akaganéite followed by reprecipitation of goethite and/or hematite. The rate-determining step was the dissolution of akaganéite. Silicate species retarded the formation of goethite + hematite principally by inhibiting dissolution of akaganéite; to a lesser extent, they interfered with the nucleation of goethite. Silicate modified the morphology of goethite, but not hematite.Comparison of the transformation behavior of akaganéite with that previously observed for ferrihydrite indicated that the composition of the reaction product depended strongly on the transformation conditions, i.e., pH and the presence of foreign species. The nature of the solid precursor was important insofar as its degree of crystallinity governed the dissolution kinetics and its surface properties influenced interaction with any foreign species in the system.
Reorientation differential cross sections at high energy

The angular momentum decoupling approximations, used extensively in approximate calculations for complex systems, are evaluated here in extensive comparisons with exact calculations for a heteronuclear system with a moderately large dipole moment at high enough energy that there are many open rotational states. Orientation‐dependent differential cross sections for He–SiO rigid‐rotor scattering calculations at high translational energy are presented. Coupled states and recoupled states results are compared with those of close coupling at a total energy of 27 meV. Although the coupled states (CS) method approximates exact calculations by ignoring m coupling in the body frame, the l‐averaged CS results are good for orientation‐dependent differential cross sections. The l‐averaged form of recoupled states makes significant improvements over the l‐averaged form of coupled states for orientationally elastic transitions and for large‐j transitions. As in past studies, the l‐initial and l‐final forms of coupled and recoupled states are found to be inferior to the l‐averaged form. Orientation‐dependent integral and degeneracy‐averaged differential and integral cross sections are also discussed.
1 Deltaic Sedimentary Environments in the Niger Delta , Nigeria 1

9 This study is focused on the geomorphology of surface sedimentary environments contained in the fluvial, tidal 10 and wave-dominated areas of the Niger Delta. GIS techniques applied to high-quality Landsat and SPOT images 11 were used to identify and map landforms and processes, as well as quantitatively characterise their metrics and 12 spatial distribution. A detailed analysis shows that the extent of the Niger Delta is 70,000 km, contrary to 13 previous publications that reported 75,000 km. The delta has also been remapped and classified into mega 14 sedimentary environments: the upper deltaic plain is 69% of the total extent, while the lower deltaic plain and 15 delta front are 25% and 6% respectively. Other subunits were distinguished and mapped within the upper deltaic 16 plain such as fluvial channels, point bars, braid bars, oxbow lakes, and other lakes. Tidal channels, beaches and 17 spits were identified in the lower deltaic plain and delta front. The geometries of these sedimentary bodies 18 (landforms) appear to be relatively scale-invariant, thus meaning that from the measurement of some 19 dimensional parameters (e.g. the length) it is possible to estimate all others (e.g. the width and overall extent). 20 This is an aspect of great relevance in subsurface analyses where it is often difficult to predict the extent of 21 sedimentary bodies. The correlation between channel width and length (r =0.9), is the strongest relationship 22 found between sedimentary body metrics. 23 24

Haematological and Biochemical Parameters of Broiler Chicken Supplemented with Humic Acid in the Drinking Water

This study was conducted to evaluate the effects of supplementing humic acid in the drinking water on some haematological and biochemical parameters of broiler chickens. One hundred and twenty (120), day-old Arbor Acre broiler chicks were randomly divided into three treatments in a completely randomized design. Each treatment of forty birds was replicated 4 times with 10 chicks per replicate and the experiment lasted for 56 days. Treatment I served as the control without humic acid in the drinking water while, treatment II was supplemented with 1 mL/L humic acid and treatment III was supplemented with 2 mL/L of humic acid. Results obtained showed that supplementation with humic acids had no significant effect (P > 0.05) on haematological indices of the broiler chickens. Significant (P<0.05) reduction in serum level of uric acid was achieved as the level of supplementation of humic acid increased while, serum phosphorus and calcium concentrations were significantly (P<0.05) increased with humic acid. Liver function enzymes were not significantly (P>0.05) affected because the activity of serum alanine transaminase and aspartate transaminase were similar among all treatments. The results indicated that humic acid supplementation had a beneficial effect on mineral absorption and detoxification as revealed through uric acid concentration of broiler chickens.
International Capital Flows and Industrial Performance in Nigeria (1990-2015) Cointegration, DOLS and Granger Causality Approach

Article History Received: 16.11. 2018 Accepted: 25.11. 2018 Published: 30.11. 2018 Abstract: It has been observed in the recent time that the bulk of studies on foreign capital flows in Nigeria focused on aggregate economic performance, neglecting the performance of industrial sub-sector. In order to move the frontiers of knowledge in this regard, the paper critically examined the relationship between international capital flows and industrial performance in Nigeria using Cointegration, DOLS and Granger Causality Approach. The study extracted data from CBN Statistical Bulletin and UNCTAD investment report from 1990-2015. Consequently, in order to address the objective of this study necessary diagnostic tests such as unit roots, co-integration and Pairwise Granger Causality Tests were estimated. The findings that emerged from this paper is as follows: long-run effect shows that foreign direct investment and external debt have a significant positive relationship with industrial performance in Nigeria. However, the remittances though have a positive relationship with industrial performance in Nigeria, but are not significant. Also, there is a unidirectional causality which runs from industrial performance to FDI inflows in Nigeria. Hence, this paper recommends that Nigerian government should see inflows of foreign capital as a viable catalyst that has the capacity to propel the expansion of the country`s industrial sector, and the policy makers in the country should embark on policy measures that will ensure the sustainability of foreign direct investment inflows and external debt towards the direction of industrial sectors in Nigeria. In the same vein, larger percentage of remittances should be tailored towards industrial sector in the country. If foreign capital flows is sustained there will be industrial revolution in the economy in the nearest future.
