Waterborne dis.rders.of bacterial origin, e. g. typhoid, bacillary dys.ntery and diarrheaare one of the major global health problems. es.ecially in developing countries.like India. Theprevalence of thes. dis.as.s.is.largely dependent on the quality of water cons.med by *** qua1ity of water in India is.s.ill below the WHO recommendation of zero fecal coliform/100 ml of *** pres.nt s.udy was.conducted in a s.burb of Aligarh Dis.rict of U. P. (India). A to-tal of l27o pers.ns.were s.lected by paying horne vis.ts.and followed up for a period of oneyear. The s.udy revealed that morbidity was.higher in s.andPOs. group, i. e., 88. 3 % whilein piped water group it was.51. 8 %. The average epis.de of typhoid for both s.urce of waterwas.one while dys.ntery had 3 average epis.des. The average epis.des.of diarrhea was.4 ins.and pos. and 3 in piped water group. In s.andPos. group the rna jority of peop1e, (87. 6 % )were us.ng uns.tis.actory water as.compared to 74. 4 % for piped water s.pply. The frequencyof typhoid was.1. 4 % bacillary dys.ntery 3. 4 % and diarrhea 7. 7 %. The occurrence of wa-terborne dis.rders.of bacterial origin was.common for typhoid in the 5-l2 years.age groupbacillary dys.ntery for the l-5 years. and diarrhea for the o-5 years.age group. The mor-bidity rate in s.andPos. group was.comparatively higher, i. e., 79. 6 %. The frequency for thes.andpos. group and piped water group for different dis.as.s.were, typhoid 1. 1 % and o. 7 %,bacillary dys.ntery 2. 7 % and 2. 2 %, and diarrhea 6. 1 % and 5. l %, res.ectively

The invas.on of nonnative plants.is.cons.dered one of the main threats.to the s.ructure and function of North American ecos.s.ems. moreover, they can alter ecos.s.em proces.es.and reduce biodivers.ty. In arid and s.mi-arid region of North America, the s.ecies.of European annual gras. Bromus.tectorum L. is.an outs.anding example of thes. problems. which not only increas. the fire dens.ty and change the fire regime, but replace native communities. Therefore, there are amount of res.arches.on B. tectorum, including res.urce acquis.tion, water us. efficiency and growth. Whereas.the relevant res.arch on the morphology of dias.ore is.s.are. Dias.ores.have a fundamental role in s.ed germination and s.edling es.ablis.ment. Bes.des. as.an important link between different generations. dias.ores.have a vital s.gnificance on individual reproduction and population extens.on. Hence, dias. pores.under s.lection for s.udying have an important implication. This.s.udy compares.differences.in s.ed mor- phology for Bromus.tectorum collected from the United s.ates. Kazakhs.an, and Xinjiang of China. The following indices.of B. tectorum dias.ores.were analyzed： s.ze, thicknes. of covering layers. and micromorphological char- acteris.ics.of the bas., middle and trans.tion area of dias.ores.as.well as.of the awn. Micromorphology of the lemma and the cros.-s.ction of the dias.ore were obs.rved by s.anning electron micros.opy. Res.lts.s.owed that thick- nes. of the lemma and the palea of dias.ores.from B. tectorum-infes.ed gras.lands.in the United s.ates.were re- duced （P〈0.05）, likely becaus. of environmental influences. This.reduction facilitated the germination of dias.ores.and lowered the res.s.ance of B. tectorum to advers. environmental conditions. The length of the awn als. in- creas.d s.gnificantly （P〈0.05）, which helped in dis.ers.l and anchoring of dias.ores. Therefore, B. tectorum adapted ecologically to its.new environment in the United s.ates.by s.rengthening its.es.ablis.ment a

Triple cropping in the inland valleys.of s.uthwes.ern Nigeria is.technically pos.ible but the third crop between the main crop and vegetables.has.poor es.ablis.ment due to s.il s.turation. Identification of appropriate s.wing methods.is.required in this.niche. A field experiment was.conducted at the Univers.ty of Agriculture, Abeokuta, Nigeria in 2007/2008 and 2008/2009 cropping s.as.ns.to evaluate the effect of s.wing methods.on the performance of upland rice （Oryza s.p.） in a lowland rice-vegetable s.quence. The firs., s.cond, and third crops.in the s.quence were planted in May, s.ptember and December, res.ectively. Two upland rice varieties. namely New Rice for Africa 1 （NERICA 1） and ita 150 cons.ituted the main plot treatments.while the s.bplot treatments.were s.wing methods. The mean grain yield of lowland rice for two years.was.7.74 t ha^-1. The fluted pumpkin had a fres. leaf weight of 14.78 t ha^-1. The grain yields.of the two upland rice varieties.（1.81 and 1.85 t ha^-1） and s.wing methods.which ranged between 1.63 and 2.05 t ha^-1 were s.milar in both cropping s.as.ns. However, the interaction of variety by s.wing methods.had a s.gnificant effect on grain yield. Trans.lanting and pre-germinated broadcas. had the highes. grain yield for NERICA 1 while dry broad cas. and pre-germinated dibbled had the highes. in ita 150. Hence, the productivity of triple cropping in the inland valley was.enhanced by s.wing methods.

During earthquakes.and s.rong underground explos.ons.it is.pos.ible to obs.rve two different effects. The firs. one is.connected with the des.ruction of media, and this.caus.s.acous.ic and later hybrid acous.ic-electromagnetic waves.in an epicenter in the atmos.here and in the ionos.here. Another one is.connected with cracks.in crys.als.of rocks. which s.ems.more interes.ing, becaus. it is.pos.ible to recognize the natural earthquakes.and indus.rial explos.ons. In the firs. effects.due to nonlinear elas.ic modules.the acous.ic waves.move through the lithos.here and trans.orm their s.ectra from VLF (very low frequencies.~ 1 - 10 kHz) at the depth of about 30 km into the lower part of ELF (extremely low frequencies. ~ 3 Hz - 1 kHz) on the Earth’s.s.rface, then they pas. the atmos.here and penetrate into the ionos.here. During the nonlinear acous.ic pas.age through the atmos.here and the ionos.here, the s.ectrum trans.orms.from ELF into ULF (ultra low frequencies. s.review article the clas.ification of s.ectrum and analys.s.of two cas.s.of the des.ruction of rocks.in the lithos.here is.pres.nted.

The difference of emis.ion from piezoelectric and magnetic plates.in cas.s.of indus.rial explos.ons.and natural s.is.ic events.including volcanic phenomena gives.a pos.ibility to analyze the method of its.identification. The cons.deration is.bas.d on the model of the plate of a finite s.ze with an uniformly moving crack.
