Reducin. sugar in.jam has an.effect on.the physico-chemical as well as sen.ory properties of the jam. To compen.ate for some of the fun.tion.l properties lost, other co-solutes may be used. Therefore the objective of this study was to use gum Arabic from Acacia sen.gal var. keren.is in.formulation.of a reduced sugar jam from plums an. pin.apple fruits. The in.ovatively prepared jam was subjected to sen.ory evaluation.by a semi-train.d pan.l. Twelve formulation. were prepared in.factorial arran.emen. in.a completely ran.omized design. The products were rated usin. a seven.poin. hedon.c scale for colour, taste, texture/spreadability, mouth feel an. gen.ral acceptability. Data were an.lysed usin. sAs, 2004 (version.9.1.3) to perform an.lysis of varian.e an. determin. the least squares mean. for each variable. The main.effect of the study was the level of gum Arabic at 15% an. 20% w/w, level of sugar con.en. at 30 an. 35% w/w, an. the type of fruit. A con.rol product was prepared for the two sugar levels but without gum Arabic. sign.fican.e was established at p sen.gal var. keren.is is bein. reported.

jams an. marmalades are some of the most popular food products because of their low cost, all year lon. availability an. appealin. sen.ory properties. These products are described as gels with pectin.as the gellin. agen. used in.its formulation. Gels are a form of matter in.ermediate between.a solid an. a liquid. They con.ist of polymeric molecules cross-lin.ed to form tan.les, an. in.ercon.ected molecular n.twork immersed in.a liquid medium. However, the jams an. marmalades require stabilization.by hydrocolloids. The most common.hydrocolloid stabilizer is pectin.which is available as a low methoxy pectin.or high methoxy pectin. Un.ortun.tely, un.er mechan.cal stress, pectin.gels may be damaged leadin. to the release of colloidal water. The release of the colloidal water is termed as syn.resis. This problem may be solved by in.egratin. pectin.with other stabilizers havin. thicken.n. properties. jams were prepared usin. plums an. pin.apples while marmalades were prepared from oran.es an. lemon.. Gum Arabic from Acacia sen.gal var. keren.is was added in.the ran.e of 1% - 5% which fell within.the additives category.

Travel time through a rin. road with a total len.th of 80 km has been.predicted by a viscoelastic traffic model(VEM), which is developed in.an.logous to the n.n.n.wton.an.fluid flow. The VEM expresses a traffic pressure for the un.ree flow case by space headway, en.urin. that the pressure can.be determin.d by the assumption.that the relevan. secon. critical soun. speed is exactly equal to the disturban.e propagation.speed determin.d by the free flow speed an. the brakin. distan.e measured by the average vehicular len.th. The VEM assumes that the soun. speed for the free flow case depen.s on.the traffic den.ity in.some specific aspects, which en.ures that it is exactly iden.ical to the free flow speed on.an.empty road. To make a comparison. the open.n.vier-stokes type model developed by Zhan.(ZHAn., H. M. Driver memory, traffic viscosity an. a viscous vehicular traffic flow model. Tran.p. Res. Part B, 37, 27–41(2003)) is adopted to predict the travel time through the rin. road for providin. the coun.erpart *** the traffic free flow speed is 80 km/h, the brakin. distan.e is supposed to be 45 m,with the jam den.ity un.quely determin.d by the average len.th of vehicles l ≈ 5.8 m. To avoid possible sin.ular poin.s in.travel time prediction. a distin.uishin. period for time averagin. is pre-assign.d to be 7.5 min.tes. It is foun. that the travel time in.reases mon.ton.cally with the in.tial traffic den.ity on.the rin. road. Without ramp effects, for the rin. road with the in.tial den.ity less than.the secon. critical den.ity, the travel time can.be simply predicted by usin. the equilibrium speed. However, this simpler approach is un.vailable for scen.rios over the secon. critical.

Vehicular n.tworks (VAn.T) are the largest real-life paradigm of ad hoc n.tworks which aim to en.ure road safety an. en.an.e drivers’ comfort. In.VAn.T, the vehicles commun.cate or collaborate with each other an. with adjacen. in.rastructure by exchan.in. sign.fican. messages, such as road acciden. warn.n.s, steep-curve ahead warn.n.s or traffic jam warn.n.s. However, this commun.cation.an. other assets in.olved are subject to major threats an. provide n.merous opportun.ties for attackers to laun.h several attacks an. compromise security an. privacy of vehicular users. This paper reviews the cyber security in.VAn.T an. proposes an.asset-based approach for VAn.T security. Firstly, it iden.ifies relevan. assets in.VAn.T. secon.ly, it provides a detailed taxon.my of vuln.rabilities an. threats on.these assets, an., lastly, it classifies the possible attacks in.VAn.T an. critically evaluates them.

In.roduction. The occurren.e of tuberculosis (TB) durin. the follow-up of Con.ective tissue diseases (CTD) is a particular situation.often.posin. real diagn.stic problems. This is an.association.described in.the literature. Patien.s an. methods: We con.ucted a retrospective an. descriptive study at the in.ern.l medicin. departmen. of Aristide Le Dan.ec Hospital. The purpose of this study was to determin. the treatmen. that patien.s followed for CTD an. sufferin. from TB took before the occurren.e of this on.. Results: Durin. a study period of 11 years an. 6 mon.hs, 21 cases of TB were diagn.sed in.602 cases of CTD (0.03%). The predomin.n.e was female with a sex ratio (H/F) of 0.6. The median.age was 42 years old. The majority of cases origin.ted from the Dakar region.(13 patien.s or 61.9%) an. 85.7% had previous follow-up exclusively in.modern.medicin. an. 21 cases (95%) received the CTD’s treatmen.. This con.isted of predn.son. (90.5%) combin.d with methotrexate (52.4%), azathioprin. (23.8%) or cyclophosphamide (19.4%). The respective median. doses of these drugs were 12.5 mg per day for predn.son., 13.5 mg per week for methotrexate an. 100 mg per day for azathioprin.. The median.duration.of patien. follow-up was 36 mon.hs. The cumulative dose of predn.son. durin. this period was 23.6 g an. that of methotrexate 2.25 g. CTD were domin.ted by rheumatoid arthritis (RA) (57.1%), an. systemic lupus (19%). Isolated cases of systemic scleroderma, primary sjôgren. sHARP syn.rom, mixed con.ective tissue disease, an. multiple autoimmun. syn.rom were n.ted. TB was localized in.95% of cases, readily bilateral an. poorly dissemin.ted. The respective median. diagn.stic delays for systemic disease an. TB were 21 mon.hs an. 5 mon.hs.
