The design.of space-efficien. support hardware for built-in.self-testin. is of great sign.fican.e in.very large scale in.egration.circuits an. systems, particularly in.view of the paradigm shift in.recen. times from system-on.board to system-on.chip techn.logy. The subject paper proposes a n.w approach to design.n. aliasin.-free or zero-aliasin. space compaction.hardware targetin. specifically embedded cores-based system-on.chips for sin.le stuck-lin. faults exten.in. well-kn.wn.con.ept from con.en.ion.l switchin. theory, viz. that of compatibility relation.as used in.the min.mization.of in.omplete sequen.ial machin.s.

Polypyrrole (Ppy) was syn.hesized usin. Ammon.um Peroxy Disulfate (APS) as oxidan. in.a stan.ard ratio of mon.mer to oxidan.s at 5℃. Attempts were made to in.rease the electrical con.uctivity by usin. various dopan.s viz. Lithium per Chlorate (LiClO4), para-Toluen. Sulfon.te (p-TS) an. n.pthalen. Sulfon.c acid (n.A). The materials were characterized usin. FTIR, X Ray diffraction.an. SEM. The electrical con.uctivity was measured by two probe method an. was foun. to be in.the ran.e of 10-3 S/cm. Thin.films of these preparation. were casted on.the in.erdigited electrodes to study the detection.of gas such as ammon.a. It was foun. that for the pure Ppy when.ammon.a gas was allowed to flow in. there was a sudden.in.rease in.the curren., which decreased rapidly when.gas was stopped. However when.Ppy doped with p-TS, n.A an. LiClO4, the tren. was reversed.

An.hropogen.c activities are in.reasin.ly catalyzin. n.tural climatic factors that drive lan. cover chan.e at differen. spatial scales. Available lan. cover data of the Mara River basin.however give a broader picture of the en.ire basin.regardless of the heterogen.ity that exists at the sub-catchmen. level. This study sought to establish sub-catchmen. specific in.ormation.on.lan. cover chan.es through examin.tion.of satellite images of four Mara River sub-catchmen.s (Amala, n.an.ores, Talek an. San. River) for the period 1987-2017. The relation.hip between.temperature, rain.all an. lan. cover was also computed. In.addition. a household survey an. focus group discussion. were con.ucted in.each sub-catchmen.s to establish the socio-econ.mic impacts of lan. cover chan.e on.the commun.ty’s wellbein.. Forest cover was domin.n. in.Amala (39.8%) an. n.an.ores (43.7%) sub-catchmen.s in.1987 but by 2017 crop lan.s had surpassed forest cover in.the two sub-catchmen.s, accoun.in. for 53.2% an. 45.7%, respectively. However, in.Talek (52.8%) an. San. River (47.4%) sub-catchmen.s, grasslan. was the domin.n. lan. cover type in.1987 an. after the 30 year period, grasslan.s remain.d domin.n. in.San. River, while shrub lan. became domin.n. in.Talek sub-catchmen.. A weak positive correlation.was observed between.rain.all an. forest cover, shrub lan. an. croplan., while a n.gative correlation.was observed between.rain.all an. bare lan.. Average temperature showed a positive moderate correlation.with bare lan. an. built up areas. An.lysis of survey data revealed that livestock keepin., temperature in.rease, type of trees, education.level of household head an. weak en.iron.en.al laws were the main.drivers of lan. cover chan.e (P −0.587), bean. (r = −0.5459), sorghum (r = −0.351), cow peas (r = −0.544), an. pigeon.peas (r = −0.337). Focus group discussion. participan.s were supportive of en.iron.en.al protective measures to reverse n.gative lan. cover chan.es

This paper presen.s a model derived for quan.itative evaluation.an. prediction.of the con.en.ration.of phosphorus removed durin. pyro-hydro ben.ficiation.of iron.oxide ore. Potassium hydroxide was used as the leachin. solution.an. the reaction.vessel con.ain.n. the solution.an. ore was heated at a temperature of 600℃ for 10 min.tes. The results of the in.estigation.in.icates that the model;P = (e0.7827) S predicts the con.en.ration.of phosphorus removed, based on.the con.en.ration.of sulphur simultan.ously removed. It was observed that the validity of the model is rooted in.the expression.ln. = ln. + ln. where both sides of the expression.are approximately equal to 4. The maximum deviation.of the model-predicted con.en.ration.of removed phosphorus from the correspon.in. con.en.ration.obtain.d from the experimen. was less than.3%. The con.en.ration. of phosphorus removed per un.t mass-in.ut of iron.oxide ore as obtain.d from experimen. an. derived model are 0.8917 an. 1.0354 mg/kg g-1 respectively. Similarly, the con.en.ration. of phosphorus removed per un.t con.en.ration.of removed sulphur as obtain.d from experimen. an. derived model are 1.8838 an. 2.1874 mg/kg (mg/kg)-1 respectively. This implies that the con.en.ration.of phosphorus removed is approximately equal to the con.en.ration.of simultan.ously removed sulphur durin. the ben.ficiation.process.

Mass con.en.ration. of PM10 an. PM2.5 for Jan.ary 2012 up to October 2013 were measured at two sites;a suburban.area, Riyadh airport (AP) an. an.urban.area, Kin. Fahd road district (KF) (den.ely trafficked site). Daily con.en.ration. of both PM10 an. PM2.5 measured at these two sites were highly variable. The temporal variation.observed either for PM10 or PM2.5 was associated main.y with the dust even.s. The an.ual pattern.of PM10 an. PM2.5 at the AP station.shows a sign.fican. in.rease in.sprin. an. summer (dusty season.) where mon.hly mean.con.en.ration. of up to 696 μg·m-3 PM10 were recorded in.March. PM10 con.en.ration. durin. win.er mon.hs are sign.fican.ly lower, with 65 μg·m-3 measured in.n.vember an. 78 μg·m-3 measured in.December. Jan.ary exhibits PM10 con.en.ration. little above 100 μg·m-3. Both PM10 an. PM2.5 showed substan.ial variation. at these two mon.torin. station. durin. the study period. In.the ur-ban.station.(Kin. Fahd), average an.ual PM10 varied by up to roughly a factor of two. This variation.implies that local emission.sources in.this site often.con.ribute much (i.e. greater than.half) of the PM10 mass on.an.ual average. The variation.of mon.hly (temporal) mean.PM10 at KF station.showed more or less similar results to the AP station. Higher con.en.ration. were observed durin. sprin. an. summer (12%, 17% an. 13% in.Feb., March an. April respectively an. 17, 15% durin. Jun. an. July). Startin. from September an. October, PM10 con.en.ration. started to drop to 7% an. 8% respectively. The relation.hips between.the mean.values of suspen.ed particle con.en.ration. an. meteorological variables (relative humidity ambien. temperature an. win. speed) were an.lyzed. The results demon.trate that the in.luen.e of weather factors upon.dust particulates is largely in.on.lusive. However, At KF station.a moderate positive correlation.was observed between.win. speed an. PM.

The population.ten.s to con.ume foods that in.addition.to their n.trition.l values can.offer some ben.fits to their health. There are man. epidemiological eviden.es an. research studies in.an.mal models suggestin. that diet plays an.importan. role in.breast can.er preven.ion.or progression. This review summarized some of the relevan. researches about n.trition.an. can.er durin. the last years, especially in.breast can.er. The an.lysis of probiotics an. fermen.ed products con.ain.n. lactic acid bacteria in.can.er preven.ion.an./or treatmen. was especially discussed. It was observed that a balan.e of fatty acids similar to those of tradition.l Mediterran.an.diet, the con.umption.of fruits an. vegetables, dietary fiber in.ake, vitamin.supplemen.ation.are, alon. with the in.ake of probiotic products, the most exten.ivelystudied by the n.gative association.to breast can.er risk. The con.umption.of probiotics an. fermen.ed products con.ain.n. lactic acid bacteria was associated to reduce breast can.er risk in.some epidemiological studies. The use of an.mal models showed the modulation.of the host's immun. respon.e as on. of the importan. effects associated to the ben.fices observed with most probiotics. However; future assays in.human.are very importan. before the medical commun.ty can.accept the addition.of probiotic or fermen.ed milks con.ain.n. lactic acid bacteria as supplemen.s for can.er patien.s.

It is well-kn.wn.that a product or a system is sustain.ble if it is econ.mically viable, socially acceptable an. en.iron.en.ally frien.ly. Load bearin. mason.y is on. such example which is quite sustain.ble, especially if the mason.y un.ts are locally available. It is importan. to quan.ify the en.iron.en.al ben.fits an. cost, if an.altern.tive to an.existin. techn.logy is to be suggested. Of course the issues related to acceptan.e have to be discussed an. addressed. This paper presen.s the quan.ification.of embodied en.rgy an. cost of lime-pozzolan.-cemen. (LPC) geopolymer based mason.y un.ts made usin. locally available bulk in.redien.s viz. tan.-bed soil (TBS) an. brick-powder (BP). The mason.y adobe un.ts developed have achieved the target performan.e in.terms of stren.th, low water absorption.an. relative ease of production. Simultan.ously the issues related to cost are also discussed in.this paper. The studies have revealed that the bulk con.ributor to embodied en.rgy an. cost of geopolymer adobes are the alkalin. materials viz sodium hydroxide an. sodium silicate. However, the embodied en.rgy an. cost per un.t stren.th appears to be better than.that of con.en.ion.l table moulded bricks in.south In.ia, especially when.alkalin. solution.at 2M con.en.ration.is used with LPC.

Tun.sten.copper an. molybden.m copper composites, with weight percen. copper in.the ran.e of 20% - 40%, have been.produced usin. the spark plasma sin.erin. (SPS) techn.que. Other specimen. havin. similar composition. were also developed usin. the con.en.ion.l techn.ques of Liquid Phase Sin.erin. (LPS) an. In.iltration. Electrical con.uctivity measuremen.s showed that the specimen. produced by the SPS process had substan.ially higher levels of electrical con.uctivity than.those produced by the other methods. Relative den.ity measuremen.s showed that the SPS specimen. achieved very high den.ification. with relative den.ities in.the ran.e of 99.1% - 100%. On.the other han., the specimen. produced by LPS an. in.iltration.had relative den.ities in.the ran.e of 88% - 92% an. 96% - 98% respectively. The superior con.uctivity of the SPS specimen. has been.attributed to the virtually full den.ification.achieved by the process. The effect of porosity on.electrical con.uctivity has been.discussed an. three stan.ard models were assessed usin. results from porous sin.ered skeleton. of pure tun.sten.an. pure molybden.m.
