El sistema electoral de Bélgica y sus reformas electorales
Authors: Fernández-Esquer Carlos 
Published: April 2020

El presente artículo aborda el estudio del sistema electoral de la Cámara de Representantes belga y sus reformas electorales. Bélgica fue el primer país europeo en adoptar un sistema de representación proporcional y, desde entonces, sus elementos centrales han exhibido una extraordinaria estabilidad. Sin embargo, con el cambio de siglo, el gobierno de coalición liderado por el liberal Guy Verhofstadt situó el debate sobre las reformas institucionales en el centro de la agenda política. Ello condujo a una reforma electoral que supuso la «provincialización» del mapa electoral, el establecimiento de una barrera electoral del 5 por ciento y la reducción a la mitad del peso de voto de lista. En 2012, se produjo la última reforma electoral, que consistió en la división de la polémica circunscripción de Bruselas-Halle-Vilvoorde. Este último episodio evidencia la complejidad del modelo federal belga, de carácter consociacional, bipolar y con dinámicas centrífugas.This paper deals with the study of the electoral system of the Belgian House of Representatives and its electoral reforms. Belgium was the first European country to adopt an electoral system of proportional representation and, since then, its main elements have exhibited extraordinary stability. However, with the turn of the century, the coalition government headed by the liberal Guy Verhofstadt put the debate on institutional reforms at the center of the political agenda. This led to an electoral reform that involved several novelties: the «provincialization» of the electoral map, the establishment of a 5 percent threshold and the reduction of the list vote weight by half. In 2012, there was the last electoral reform, which consisted of the division of the controversial constituency of Brussels-Halle-Vilvoorde. This last episode shows the complexity of the Belgian federal model, consociational, bipolar and with centrifugal dynamics.

Chloramphenicol a broad spectrum antibiotic was tested on broiler birds to evaluate the effect of its prolonged administration on heamatological parameters, identification of histopathological changes on organs (Liver, Spleen and Kidneys) and to determine if prolonged effect has effects on weight gain and mortality rate.
One hundred and twenty day old chicks from Kamadex Ibadan were used for the experiment. The birds were assign to two (2) treatments and control group each replicated in a Complete Randomized Design (CRD), birds in treatment one (T1) were administered normal dose of Chloramphenicol (250 mg/Kg), while treatment two (T2) were served with triple dose in medicated water served ad-lib for seven weeks, while the control (T3) were served with un-medicated water ad-lib. Samples (blood, liver, kidney and spleen) were collected and analyzed after 8 weeks of the experiment.
Birds showed significant variations in heamatological values across treatments. Lymphocysts count: treatment two (T2) was higher than the treatment one (T1) whereas that of (T3) was found to be less, compared to those of T1 and T2. Heterophils: T3 was higher than the T1 while that of T2 was less as compared to T3 and T1. Basophil: T1 was higher than T3 while that of T2 was less. A lower value was observed in weight gain with birds on T2 as compared to T1 and T3. The liver of birds on T1 and T2 were significantly larger than those on T3. High mortality was recorded in birds on T2 compared to those in T3 and T2.
The histopathological pictures of the liver, kidney and the Spleen depict a varying degree of necrosis and hemorrhagic foci on all the organs, the changes were much severe on T2 as compared to those of T1 and T3.

Published: April 2020

Aim: The present study was conducted to assess and compare the personal values among male adolescents in the families categorized under three group based on their family income as Low-Level Income Group (LLIG), Medium-Level Income Group (MLIG) and High-Level Income Group (HLIG).
Sample: The total sample consisted of 90 male adolescents in the age group of 17-19 years from the two selected colleges of GB Pant University of Agriculture and Technology (College of Home Science and College of Agriculture), Pantnagar.
Sample Design: From the selected colleges, the students were randomly drawn under three classified groups within the age group irrespective of their degree program.
Sample Selection: The list of male students enrolled in I and II year (of both Agriculture and Home Science within the age group of 17-19 years) made was collected from the office of four colleges and scrutinised under three groups based on their family income. The sample of 30 male adolescent students was randomly selected under each group constituting the total sample of 90 students. The Deans of both the colleges were personally contacted for seeking permission to have rapport and collect the information legally.
Tools: Self-structured general information questionnaire along with the Personal value questionnaire by Sherry and Verma [8] was administered to collect the data.
Results: The results revealed that the family income plays a crucial role in the personal values of adolescents. Except for social and religious values, the students from HLIG are having a significantly high level of personal values when compared to LLIG and MLIG. Hence, the higher the family income, the more focus on personal development and so the improved personal values of the younger generations.
Conclusion: We were able conclude that the family income plays a crucial role in the personal values of adolescents.

The study was carried out for vertical characterization of soils at three permanent benchmark sites (Udna, Khamaria and Magarmuha) of Jabalpur district for their physical properties under the Rice-Wheat cropping system. Variability in the proportion of primary soil particles (texture), bulk density, distribution of different sized soil aggregates and mean weight diameter (MWD) of soil aggregates along the depths were studied as these influence the water and nutrients retention and release behaviour of soil. A total of 45 undisturbed soil samples were collected from selected sites at 0-20, 20-40, 40-60, 60-80 and 80-100 cm depths and brought to the laboratory for their characterization and the data thus obtained were analysed in split-plot design taking sites as main plot and depth as sub-plot treatments. Results showed that variability in the sand, silt and clay contents, bulk density, fractions of different size soil aggregate (>5.0, 5.0-2.0, 2.0-1.0, 1.0-0.5,0.5-0.25,0.25-0.1 and <0.10 mm) and mean weight diameter of soil aggregates were significant across the sites and soil depths. However, the interaction effect of sites and soil depth on the above properties was found non-significant except for fraction of < 0.1 mm size aggregate. It has been analysed from the study that sand, silt and clay contents, bulk density, fractions of different size aggregate and mean weight diameter of soil aggregates vary significantly (ρ=0.05) at spatially and vertically.
Optimization of Juice and Total Soluble Solids Concentration for the Preparation of Wild Jamun Syrup: Effect of Packaging Materials and Temperature Conditions on Nutritional Quality during Storage
Authors: Bhatt Kanchan , Thakur N. S. , . Hamid , Thakur Abhimanyu , Sharma Chetna 
Published: April 2020

Jamun (Syzygium cumini L.) is a wild fruit with major importance due to its antioxidant activity, anthocyanins content and exotic taste besides high medicinal value. This fruit is known for its antidiabetic properties as its seeds contain glucoside “Jamboline”. Due to its perishable nature and neutraceutical importance present studies have been conducted for the preparation of syrup. Various TSS (65 and 70 °B) and juice (25, 30, 35 and 40%) ratios have been attempted to optimize proper syrup combination. The two packaging materials i.e. glass and PET (Polyethylene terephthalate) bottles were used to pack jamun syrup prepared by the best selected combination and stored for 6 months under ambient (18-22°C) and refrigerated temperature conditions (4–7°C). Based on organoleptic and some physico-chemical characteristics, syrup prepared with 35% jamun juice, 65°B TSS and 1.50% acid was considered best among 8 different treatment combinations of juice and TSS. Jamun syrup could be stored safely for a duration of six months under both the ambient and refrigerated conditions without much difference in various quality parameters. Nevertheless, both PET and glass bottles have been considered appropriate as packaging material, with reasonably fewer changes taking place in glass bottles kept in refrigerated conditions.

Published: April 2020

The aim of this paper is to evaluate the yield and quality of 'Pérola' pineapple under increasing rates of nitrogen and potassium applied through fertigation. The experiment was conducted in a randomized block design, with four replications, in a factorial scheme (4x4), which represents four nitrogen rates (128, 256, 384 and 512 kg ha-1 of N) and four potassium rates (192, 384, 576 and 768 kg ha-1of K2O) via fertigation. The evaluations consisted of physical and chemical fruit characteristics and yield. Increasing nitrogen rates provided linear growth on fruit production features and the rate of 516 kg ha-1 resulted in fruits with the largest diameters. The highest total yield on 'Pérola' pineapple crop was reached on plants under the supply of 498 kg ha-1 of K2O. Rates between 523 and 583 kg ha-1 of K2O, provided the largest fruit matter and the highest fruit pulp yield. The increasing amount of nitrogen applied by fertigation resulted in linear growth on fruit pulp pH, though it did not influence the soluble solids content. The lower acid content and higher SS/acid ratio on fruits were reached with the N rates of 333 and 375 kg ha-1 respectively.

Published: April 2020

AbstractIn this study, we assess a developed novel dynamic moving phantom system that can reproduce patient three‐dimensional (3D) tumor motion and patient anatomy, and perform patient‐specific quality assurance (QA) of respiratory‐gated radiotherapy using SyncTraX. Three patients with lung cancer were enrolled in a study. 3D printing technology was adopted to obtain individualized lung phantoms using CT images. A water‐equivalent phantom (WEP) with the 3D‐printed plate lung phantom was set at the tip of the robotic arm. The log file that recorded the 3D positions of the lung tumor was used as the input to the dynamic robotic moving phantom. The WEP was driven to track 3D respiratory motion. Respiratory‐gated radiotherapy was performed for driving the WEP. The tracking accuracy was calculated as the differences between the actual and measured positions. For the absolute dose and dose distribution, the differences between the planned and measured doses were calculated. The differences between the planned and measured absolute doses were <1.0% at the isocenter and <4.0% for the lung region. The gamma pass ratios of γ3 mm/3% and γ2 mm/2% under the conditions of gating and no‐gating were 99.9 ± 0.1% and 90.1 ± 8.5%, and 97.5 ± 0.9% and 68.6 ± 17.8%, respectively, for all the patients. Furthermore, for all the patients, the mean ± SD of the root mean square values of the positional error were 0.11 ± 0.04 mm, 0.33 ± 0.04 mm, and 0.20 ± 0.04 mm in the LR, AP, and SI directions, respectively. Finally, we showed that patient‐specific QA of respiratory‐gated radiotherapy using SyncTraX can be performed under realistic conditions using the moving phantom.
A multi‐tone central divided difference frequency tracker with adaptive process noise covariance tuning
Authors: Brumana Alessandro , Piroddi Luigi 
Published: April 2020

SummaryThe problem of real‐time frequency estimation of nonstationary multi‐harmonic signals is important in many applications. In this paper, we propose a novel multi‐frequency tracker based on a state‐space representation of the signal with Cartesian filters and the second‐order central divided difference filter (CDDF), which improves the performance of the extended Kalman filter (EKF) by using Stirling's interpolation method to approximate the mean and covariance of the state vector. A crucial element of the method is the adaptive scaling of the process noise covariance matrix appearing in the filter equations, as a function of the innovation sequence, which tunes the accuracy‐reactivity trade‐off of the filter. The proposed solution is evaluated against two approaches from the literature, namely the factorized adaptive notch filter (FANF) and the extended Kalman filter frequency tracker (EKFFT). Several experiments emphasize the estimation accuracy of the proposed method as well as the improved robustness with respect to initial errors and input signal complexity. The presented method appears to be particularly efficient with rapidly varying frequencies, thanks to the update mechanism that adjusts the filter parameters based on the amplitude of the estimation error.
