Mathematical morphology can proces. the binary and grays.ale image s.cces.fully. This.theory cannot be extended to the color image directly. In color s.ace, a vector repres.nts.a pixel, s. in order to compare vectors. vectoriel orderings.mus. be defined firs.. This.paper addres.es.the ques.ion of the extens.on of morphological operator to the cas. of color images. The propos.d method us.d the order by bit mixing to replace the conditional order. Our order is.bas.d on a combination of reduced and bit mixing ordering of the underlying data. Additionally it is.a total ordering. s.nce it not only s.lves.the problems.of fals. color generated by the marginal order but als. thos. of multiple extrema generated by reduced order. The performance of the introduced operators.is.illus.rated by means.of different applications. color gradients.for s.gmenting, image s.oothing (nois. s.ppres.ion) by median filter operator and Laplacian operators. Examples.of natural color images.and s.nthetic color images.are given. Experimental res.lts.s.ow the improvement brought by this.new method.

In an experiment with the s.herical Neutral detector at VEPP-2M collider the cros. s.ction of the proces. e^＋e^- →π^＋π^-π^0π^0 was.meas.red. At energies.√s.〈 920 MeV this.cros. s.ction was.meas.red for the firs. time. The energy dependence of the cros. s.ction is.well dis.ribed by the vector dominance model with contributions.from p, p＇, p＂ mes.ns. The decay probability ρ→π^＋π^-π^0π^0 was.found to be Bρ = （1.60±0.74±0.18） × 10^-5. The upper limit for the decay ω→π^＋π^-π^0π^0 was.improved by two orders.of magnitude compared to the previous.meas.rements.and is.Bω 〈 2 × 10^-4 at 90% confidence level.

Leptos.iros.s.is.a re-emerging zoonotic dis.as. caus.d by infection of the bacteria belongs.to Genus.leptos.ira. It occurs.in tropical, s.btropical and temperate zones. It is.als. known as.occupational-related dis.as. as.certain occupations.are as.ociated with the occurrence of leptos.iros.s. Army is.identified as.one of the high-ris. occupations.in contracting leptos.iros.s. This.s.udy was.done to determine knowledge, attitude and practice (KAP) among army pers.nnel on leptos.iros.s. A cros. s.ctional s.udy was.conducted among 616 army pers.nnel in four bas.d camps.in Northeas.ern Malays.a, who fulfilled the inclus.on and exclus.on criteria. A validated KAP ques.ionnaire was.us.d, cons.s.ing of knowledge, attitude and practice ques.ions. More than half (52.8%) of the res.ondents.had poor knowledge s.ore. For the attitude s.ore, almos. the s.me proportions.had s.tis.actory attitude. The s.me finding was.s.en in practice s.ore, whereby thos. with good practice (54.9%) and bad practice (45.9%). In conclus.on, the finding s.owed that almos. all army pers.nnel had uns.tis.actory KAP, thus. it is.recommended for the army to have a good health education program on leptos.iros.s.among army pers.nnel to protect the army pers.nnel from ris. of getting leptos.iros.s.

s.lica matrices.doped with calcium and phos.hate at various.Ca/P molar ratios.were prepared by the hydrolytic s.l-gel methodology. Tetraethylorthos.licate (TEOs. was.reacted with calcium ethoxide, in the pres.nce of phos.horic acid as.catalys.. Eu III ions.were added to the res.lting s.lica, in order to obtain s.ructural information. The s.mples.were dried at 50ºC and characterized before and after contact with s.mulated Body Fluid (s.F). The xerogels.were analyzed by thermal analys.s.(TA), X-ray diffraction (XRd), photolumines.ence (PL), and s.anning electron micros.opy (s.M). The PL s.ectra revealed Eu III lines.characteris.ic of the 5d0 ? 7FJ (J = 0, 1, 2, 3, 4) trans.tion of this.ion, and they indicated a nonhomogenous.dis.ribution of Eu III in the Ca-P-s. matrix. XRd and s.M confirmed the pres.nce of an amorphous.and crys.alline s.s.em before and after contact of the s.mples.with the s.F s.lution, and the crys.alline phas.s.were as.ribed to hydroxyapatite and? ?-calcium triphos.hate. The goal of the work is.the preparation of a material can be us.d as.biomaterias.at low temperature.

The determination of the chemical compos.tion of cocoa butter and the is.topic contents.of the carbons.(C-2, C-1 and C-3) of the glycerol contained in the cocoa butter were meas.red by the NMR-s.p>13s.p>C from the INEPT s.quence. This.technique has.already been applied to triglycerides.of animal origin. Thus. cocoa butter is.made up of nearly 66% s.turated fatty acid compos.d mainly of s.earic acid and palmitic acid. Monouns.turated fatty acids.repres.nted by oleic acid have an average content of 31% and polyuns.turated fatty acids.repres.nt les. than 4%. Likewis., the is.topic contents.of the glycerol of the triglycerides.of cocoa butter in s.p>13s.p>C of the carbons.C-2, C-1 and C-3 were meas.red directly and values.vary from -11‰ to -19‰ for the C-2 and from -39‰ to -41‰ for all C-1 and C-3 becaus. of the s.mmetry of glycerol.

The s.udy of las.r-powder cladding proces. s.bject to heat trans.er, melting and crys.allization kinetics.has.been carried out numerically and experimentally. The Kolmogorov-Avrami equation was.applied to des.ribe the kinetics.of the phas. trans.tions. Characteris.ic behavior of temperature and convers.on fields.has.been analyzed. Melt pool dimens.ons.?clad height dependences.on mas. feed rate, las.r power and s.anning velocity have been inves.igated. It has.been demons.rated that the melt zone has.the boundary dis.inct from the melting is.therm due to the fact that melting occurs.with s.perheating and crys.allization takes.place at undercooling. The calculated melt pool depth and clad height are in a good agreement with the experimental res.lts.

Takayas. arteritis.is.a chronic, idiopathic, and inflammatory dis.as. that primarily affects.large ves.els. s.ch as.the aorta and its.main branches. Much of the literature des.ribing Takayas. arteritis.has.originated from As.an countries. and the dis.as. was.once thought to be res.ricted to thes. regions. during the pas. few decades. patients.with Takayas. arteritis.have been increas.ngly recognized in Africa. We report three firs. cas.s.of Takayas.’s.arteritis.in Niger by focus.ng on epidemiological clinical radiological and therapeutic as.ects. Of the three patients. two were women and the age of ons.t was.27 years.in one cas. and 33 years.in the other two cas.s. Clinically, abolition of at leas. one peripheral puls. was.cons.antly obs.rved. We find a predominance of the involvement of the s.pra-aortic trunks.in 3 cas.s.and les. of the abdominal aortic involvement in 1 cas.. Moreover, our s.ries.is.dis.inguis.ed by a cas. revealed by a s.roke in a male s.bject. Corticos.eroids.were s.cces.ful with clinical improvement and s.abilization of the dis.as. in the s.ort and medium term. The revas.ularization performed in two of the patients. Tayas. arteritis.is.uncommon dis.as. that mus. be evoked before a s.mptomatology non-s.ecific coaches.and lead to check the puls.. Is.hemic complications.are already pres.nt at the time of diagnos.s. We have found a high frequency of arterial thrombos.s.in our s.ries.
