Working Paper 19-08 - Quantifying environmental leakage for Belgium

This paper illustrates the deficiency of the production approach as a tool to measure a country's responsibility for international environmental impacts. A use approach is presented as a more suitable tool. The difference between the two approaches is determined by a better grasp of international trade, which can lead to environmental leakage when a country specialises in the production of environmentally friendly products and has the environmentally unfriendly products which it consumes produced abroad. We show that in the period 1995-2002 Belgium was on average a provider of air emission intensive products for the rest of the world. Environmental leakage was mostly negative. However, the evolution of the Belgian environmental terms of trade shows that by 2002 its imports had become considerably more air emission intensive with respect to its exports than in 1995. There are indications that this evolution is due to a considerable increase of extra-EU imports of air emission intensive products. This in turn could point to environmentally inspired offshoring. However, the currently available data do not allow us to test this hypothesis.Environmental leakage, Environmental terms of trade, Input-output analysis

Working Paper 13-09 - Qualitative Employment Multipliers for the Belgian Environmental Industry

The present paper computes cumulative employment generated by the Belgian environmental industry. Relying on Belgian input-output tables for the year 2000 and on detailed employment data (SAM sub]matrix), we investigate the patterns of the employment in the environmental industry, by considering the worker types differentiated by gender, educational attainment or a combination of these characteristics. The employment multiplier analysis of environmental employment reveals some interesting differences between employment of the overall economy and environmental employment for the level of education as well as for the gender type.

Understanding the properties of biologically active glassy materials for tissue engineering through modelling and experiment

Bioactive glasses (BGs) are amorphous materials exhibiting biocompatibility properties,gaining great interest as biomaterials for regenerative medicine. This work comprises twoparts. First, the bioactivity properties that fluoridated phosphate-based bioactive glasses(F-PBGs) exhibit once implanted, for dental repair applications, was studied. Second,the experimental design of cardiac patches, containing 45S5 bioactive glasses for cardiactissue engineering, was undertaken. [Continues.

A supermartingale argument for characterizing the Functional Hill process weak law for small parameters

The paper deals with the asymptotic laws of functional of standard random variables. These classes of statistics are closely related to estimators of the extreme value index when the underlying distribution function is in the Weibull domain of attraction. We use techniques based on martingales theory to describe the non Gaussian asymptotic distribution of the aforementioned statistics. We provide results of a simulation study as well as statistical tests that may be of interest with the proposed results.Comment: 25 pages. arXiv admin note: text overlap with arXiv:1208.1487, Submitted under the title : On The Weak Convergence Of The Functional Hill Process For Small Parameters, Ti be published in Mathematical Methods of Statistics 201

UJI FORMULASI BIOFUNGISIDA GRANULAR BERBAHAN AKTIF Trichoderma virens ENDOFIT DALAM MENGENDALIKAN Ganoderma Boninense Pat. PADA BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.)

The aim of this work is to find out the effect of granular bio fungicide formulations with the active ingredient of T. virens endophytes and to obtain the best biofungicide preparations to control G. boninense and improve the quality of oil palm seeds. The research was conducted at the experimental farm and plant disease laboratories, Faculty of Agriculture, the University of Riau from February 2017 to September 2018. The research was carried out experimentally using a completely randomized design (CRD).  The treatment tested was the Trichoderma virens formulation F0 = Control without treatment, F0- = Control negative (Ganoderma inoculant), F0 + = Positive control (15 ml Trichoderma virens inoculant + Ganoderma inoculant), F1 = 15 ml Trichoderma virens inoculant +100 g sago starch + 25 peat peat +25 g tapioca starch, F2 = 15 ml Trichoderma virens inoculant +100 g palm frond flour + 25 sago dregs + 25 g tapioca flour, F3 = 15 ml Trichoderma virens inoculant + 100 g solid +25 g talc + 25 g flour tapioca, F4 = 15 ml Trichoderma virens inoculant + 100 g cocoa shell flour + 25 g zeolite + 25 g tapioca flour. The parameters observed were the intensity of the attack of the disease, seed height, weevil diameter, number of fronds, root volume, seed dry weight, and sprout ratio. uk root. The obtained data were statistically analyzed using variant fingerprints. The average results of the analysis were continued with the BNJ test at the 5% level.  F4 treatment showed the best granular formulation for the growth and development of T. virens endophytes, inhibiting the infection of Ganoderma sp. Attack. on seedlings and better seed growth on observations of seed height, root volume, number of midribs, root crown ratio, and dry weight of oil palm seedlings

STUDIES OF MALARIA TRANSMISSION RISK FACTORS IN A TIME OF MILITARY-POLITICAL CRISIS IN BOUAKE URBAN AREA (IVORY COAST)

In order to assess the risk of malaria transmission to which populations are exposed in a time of war in besieged areas, studies were conducted between April and June, 2008, in a district of Bouaké, a town in the humid savannah of the central Ivory Coast. This study’s objective was to describe the malaria situation in an urban environment during a period of military crisis. Data were gathered from personal interviews with heads of households and direct observations. Analysis of our results has made it possible to assess the various sources of mosquito proliferation, especially anopheles malaria vectors. The presence of anopheles is associated with two factors: kennedy’s natural environment; and the deterioration of the surroundings caused by war. Indeed, the principal breeding sites encountered in kennedy are mainly comprised of vegetable and rice plots in the low land; puddles of water in the cracks resulting from damaged roads; and ruined or abandoned dwellings. The wide array of anopheles breeding sites and the deterioration of the environment are all factors which increase the risk of malaria transmission in Kennedy, where most inhabitants do not protect themselves against mosquito bites
