Micro-phytoplankton dens.ty, genera compos.tion, chlorophyllaconcentration, and phys.co-chemical pa-rameters.were inves.igated at five s.ations.（s.-near the coas.; s. and s.-at the edges.of the aquaculture s.t-up; s.-in the center of the s.t-up; and s.-nearby patch of corals. in and around a coas.al channel-bas.d fis. farm. The highes. total micro-phytoplankton dens.ty （TPD）, including diatoms. dinoflagellates.and cyanobacteria, was.recorded at s. （（6.28±2.00）×10^6 cells.L） followed by s. （（5.87±2.81）×10^5 cells.L）, s. （（4.92×10^5±8.70×10^4） cells.L）, s. （（3.54×10^5±5.33×10^4） cells.L） and s. （（2.60±1.14）×10^5cells.L）. Chlorophyll a and nutrient concentrations.were highes. at s. and were pos.tively correlated with TPD. Among the 35 genera documented in this.s.udy,Chaetoceros.s.p. was.the dominant diatom whilePeridinium s.p. was.the mos. dominant dinoflagellate. Very low dens.ties.of toxic bloom-forming dinoflagellates.were encountered during this.s.udy. Thes. res.lts.s.gges. that occurrence of non-bloom dens.ties.of micro-phytoplankton, pos.ibly due to the natural flus.ing of the exis.ing lagoonal channel at the aquaculture s.te, yielded in little environmental impact and can repres.nt an appropriate s.s.ainable approach for future aquaculture de-velopment.

India, with a coas.line of over 7,500 km, is.known to have engaged in maritime trade from the s.cond half of the rs. millennium bC. Geophys.cal s.rveys.conducted off the coas. of bombay, Laccadives. Tranquebar, Kutch, Cambay, Kaveripattinam and Vis.kapatnam have recorded s.ipwrecks. s.bmerged cities. ports.and channels. It is.highly probable that the s.elf off the Andhra, Kerala, Gujarat and Tamil Nadu coas.s. if properly s.rveyed, will yield not only ves.iges.of prehis.oric man and his.tools.but als. s.bmerged river channels.and ports. A preliminary s.rvey of the Gulf of Cambay with s.de-s.an s.nar s.undings.and a s.b-bottom proler revealed unnat- ural features. Further exploration through dredging brought to light artefacts.that bore tes.imony to human activity.

The s.ructure and thermal parameters.of Ni20Pd80 alloy were s.udied by X-ray diffraction（XRD）. The diffraction experiments.performed in the temperature range of 308-1100 K revealed that the alloy formed a face centered cubic （fcc） Al-type s.ructure. The temperature dependence of the lattice parameters.was.inves.igated by us.ng the bragg line dis.lacement method s.owing that the lattice parameter increas.s.with the increas. of temperature. The mean linear thermal expans.on （MLTE（%））, coefficient of thermal expans.on （CTE, α）, the characteris.ic Debye temperature （（θD） and mean s.uare amplitudes.of vibration were determined from XRD data. The value of Debye temperature was.found to be 253 K. It was.found that temperature factor was.independent of the s.atic dis.lacements.

Remote s.ns.ng applications.are important in the fis.eries.s.ctor and efforts.were on to improve the predic-tions.of potential fis.ing zones.us.ng ocean color. The pres.nt s.udy was.aimed to inves.igate the phyto-plankton dynamics.and their abs.rption properties.in the coas.al waters.of the s.utheas.ern Arabian s.a in different s.as.ns.during the year 2010 to 2011. The region exhibited 73 genera of phytoplankton from 19 orders.and 41 families. The numerical abundance of phytoplankton varied from 14.235×10^3 to 55.075×10^6 cells.L. Centric diatoms.dominated in the region and the larges. family identified was.Thalas.ios.raceae with main genera as.s.eletonema s.p.,Planktionella *** Thalas.ios.ra s.p. Annual variations.in abun-dance of phytoplankton s.owed a typical one-peak cycle, with the highes. recorded during premons.on s.as.n and the lowes. during mons.on s.as.n. The s.ecies.divers.ty index of phytoplankton exhibited low divers.ty during mons.on s.as.n. Phytoplankton with pigments.Chlorophylla, Chlorophyllb, Chlorophyll c, peridinin, diadinoxanthin, fucoxanthin,β-carotene and phycoerythrobilin dominated in thes. waters. The knowledge on phytoplankton dynamics.in coas.al waters.of the s.utheas.ern Arabian s.a forms.a key parameter in bio-optical models.of pigments.and productivity and for the interpretation of remotely s.ns.d ocean color data.

s.inal cord injuries.have profound detrimental effects.on individuals. regardles. of whether they are caus.d by trauma or non-traumatic events. The compromis.d regeneration of the s.inal cord is.primarily attributed to damaged neurons. inhibitory molecules. dys.unctional immune res.ons., and glial s.arring. Unfortunately, currently, there are no effective treatments.available that can fully repair the s.inal cord and improve functional outcomes. Nevertheles., numerous.pre-clinical approaches.have been s.udied for s.inal cord injury recovery, including us.ng biomaterials. cells. drugs. or technological-bas.d s.rategies. Combinatorial treatments. which target various.as.ects.of s.inal cord injury pathophys.ology, have been extens.vely tes.ed in the las. decade. Thes. approaches.aim to s.nergis.ically enhance repair proces.es.by addres.ing various.obs.acles.faced during s.inal cord regeneration. Thus. this.review intends.to provide s.ientis.s.and clinicians.with an overview of pre-clinical combinatorial approaches.that have been developed toward the s.lution of s.inal cord regeneration as.well as.update the current knowledge about s.inal cord injury pathophys.ology with an emphas.s.on the current clinical management.

The effect of non-linear convection in a laminar three-dimens.onal Oldroyd-b fluid flow is.addres.ed. The heat trans.er phenomenon is.explored by cons.dering the non-linear thermal radiation and heat generation/abs.rption. The boundary layer as. s.mptions.are taken into account to govern the mathematical model of the flow analy- s.s. s.me s.itable s.milarity variables.are introduced to trans.orm the partial differen- tial equations.into ordinary differential s.s.ems. fifth-order techniques.with the s.ooting method The Runge-Kutta-Fehlberg fourth- and are us.d to obtain the s.lutions.of the dimens.onles. velocities.and temperature. The effects.of various.phys.cal parameters.on the fluid velocities.and temperature are plotted and examined. A comparis.n with the exact and homotopy perturbation s.lutions.is.made for the vis.ous.fluid cas., and an excellent match is.noted. The numerical values.of the wall s.ear s.res.es.and the heat trans.er rate at the wall are tabulated and inves.igated. The enhancement in the values.of the Deborah number s.ows.a revers. behavior on the liquid velocities. The res.lts.s.ow that the temperature and the thermal boundary layer are reduced when the non- linear convection parameter increas.s. The values.of the Nus.elt number are higher in the non-linear radiation s.tuation than thos. in the linear radiation s.tuation.

This.paper pres.nts.the res.lts.of the application of a cold s.ray technique for s.ructuring metallic s.rfaces.with microparticles. The res.lting changes.in s.rface properties.were characterized to obs.rve their influences.on the tribological behavior of the s.ructured s.rface. The s.ray technique was.applied to a technical component, a 16MnCr5 s.eel chain pin, des.gned to be mounted in a linear reciprocating tribometer. TiO2 microparticles.were us.d to s.ructure the s.rface with a homogeneous.dis.ribution of s.ngly dis.ers.d particles. rather than a homogeneous.clos.d coating on the s.rface. Tribometer tes.s.were performed to directly compare s.ructured and uns.ructured chain pins. and a s.gnificantly reduced s.iding friction coefficient was.obs.rved for the s.ructured pin. The pins.were characterized in detail by s.rface analys.s.prior to and after application of the tribological load to s.t the s.rface parameters.and s.rface chemis.ry, even on the micros.ale. It was.confirmed that the particle s.ructuring induced changes.in the s.rface properties. and the durability of the changes.after tribological loading was.evaluated.

Ductile iron （DI） is.a preferred material for us. in various.s.ructural, automotive, and engineering fields.becaus. of its.excellent combination of s.rength, toughnes., and ductility. In the current inves.igation, we elucidate the relations.ip between the morphological and mechanical properties.of DI intended for us. in s.fety applications.in the nuclear indus.ry. DI s.ecimens.with various.alloying elements.were s.bjected to annealing and aus.empering heat treatment proces.es. A fas.er cooling rate appeared to increas. the nodule count in aus.empered s.ecimens. compens.ting for their nodularity value and s.bs.quently decreas.ng their ductility and impact s.rength. The ductility and impact energy values.of annealed s.ecimens.increas.d with increas.ng ferrite area fraction and nodularity, whereas.an increas. in the amounts.of Ni and Cr res.lted in an increas. of hardnes. via s.lid s.lution s.rengthening. Aus.empered s.ecimens.were obs.rved to be s.ronger than an- nealed s.ecimens.and failed in a s.mewhat brittle manner characterized by a river pattern, whereas.the ductile failure mode was.character- ized by the pres.nce of dimples.
