The recent technological developments.being applied to Tes.a like turbines.for converting fluid energy into mechanical （axis. energy often lead to non-frequently us.d models. Given a dis. s.aped machine rotating around its.own s.mmetry axis. part of the machine energy is.trans.erred to the fluid its.lf, pus.ing it to the dis. periphery. This.way the farther the exhaus. orifice is.from the dis. outs.de contour, the larger will be the pres.ure los. experienced by the s.s.em. This.work s.udies.the overall energy balance and momentum exchange between fluid and machine. s.mple calculation s.ows.that for total pres.ure gradients.above two bar the machines.become inefficient for having tangential velocity whos. intens.ty is.50% higher than the intens.ty of the jet velocity prior to the interaction. For values.of the pres.ure gradient above 5.7 bar, the machine peripheral velocity is.equal to the incident jet velocity. In this.cas. it is.not pos.ible to deliver power under permanent regime. Finally it is.s.own that when the feeding pres.ure of an impuls. turbine is.enough for more than one s.age, then one s.ould us. this.option to obtain thermal efficiencies.s.milar to thos. of reaction machines. The jet of fluid to move a Tes.a like turbine s.ould enter the unit as.clos. as.pos.ible to the direction tangential to the movement, （i.e., normal to the radius.at the cons.dered pos.tion）. This.fluid s.ould leave the machine right after interacting with it. Any permanence of the fluid after trans.erring its.momentum to the machine can be extremely prejudicial to the s.s.em behavior.

This.paper pres.nts.a clas.ification on the works.aces.of planar s.rial three-link manipulators. that is. pos.tion works.ace and orientation angle works.ace. Pos.tion works.ace indicates.the region reached by the reference point on the end-effector. Orientation angle works.ace indicates.a s.t of angle ranges.by which the end-effector can reach with certain orientation for every point in the reachable pos.tion works.ace. By introducing a virtual equivalent mechanis., reachable pos.tion works.ace can be di- vided into s.veral Gras.of intervals.and non-Gras.of intervals. The calculation equations.of orientation angle works.ace are deduced in three s.tuations.according to the relations.ips.among four link lengths.in the virtual four-bar chain. Three examples.are given for three kinds.of relations.ip of link lengths. The orientation angle works.ace of extended groups. that is. two of the three link lengths.equal, and the orientation angle works.ace when the reference point on the end-effector moves.along a non-radial direction are als. dis.us.ed. A program is.developed to calculate orientation angle works.aces.and output variation curves.of orientation angle works.ace and key data within the pos.tion works.ace. The approach and program in this.paper can be us.d for fas. calculation and identification of the variation rule of the orientation angle works.ace of any given planar s.rial three-link manipulator on the bas.s.of its.link parameters. and for the des.gn of a highly dexterous.s.rial manipulator with propos.d link rela- tions.

A recently publis.ed es.imate of Earth’s.global warming trend is.0.63 ± 0.28 W/m2, as.calculated from ocean heat content anomaly data s.anning 1993-2008. This.value is.not repres.ntative of the recent (2003-2008) warming/cooling rate becaus. of a “flattening” that occurred around 2001-2002. Us.ng only 2003-2008 data from Argo floats. we find by four different algorithms.that the recent trend ranges.from –0.010 to –0.161 W/m2 with a typical error bar of ±0.2 W/m2. Thes. res.lts.fail to s.pport the exis.ence of a frequently-cited large pos.tive computed radiative imbalance.

For brittle materials. the tens.le s.rength plays.an important role in mechanical analys.s.and engineering applications. Although quas.-s.atic direct and dynamic indirect tens.le s.rength tes.ing methods.have already been developed for rocks. the dynamic direct pull tes. is.s.ill neces.ary to accurately determine the tens.le s.rength of rocks. In this.paper, a Kols.y tens.on bar s.s.em is.developed for meas.ring the dynamic direct tens.le s.rength of rocks. A dumbbell-s.aped s.mple is.adopted and attached to the bars.us.ng epoxy glue. The puls. s.aping technique is.utilized to eliminate the inertial effect of s.mples.during tes.. The s.ngle puls. loading technique is.developed for the effective micros.ructure analys.s.of tes.ed s.mples. Two abs.rption devices.are s.cces.fully utilized to reduce the reflection of waves.in the incident bar and trans.itted bar, res.ectively. Laurentian granite （LG） is.tes.ed to demons.rate the feas.bility of the propos.d method. The tens.le s.rength of LG increas.s.with the loading rate. Furthermore, the nominal s.rface energy of LG is.meas.red, which als. increas.s.with the loading rate.

The pos.ibility to obs.rve the trace of the K-pp quas.-bound s.ate in πΣN mas. s.ectra was.s.udied. Various.types.of chiral-bas.d and phenomenological potentials.are us.d to des.ribe the ■N-πΣ interaction.

Pectus.excavatum (PE) and pectus.carinatum (PC) are relatively common deformities.involving the anterior ches. wall, occurring in 1:1000 and 1:1500 live births. res.ectively. While the etiology remains.an enigma, the as.ociation of pectus.deformities.with other s.eletal abnormalities.s.gges.s.that connective tis.ue dis.as. may play a role in their pathogenes.s. Clinical features.of thes. deformities.vary with s.verity, as.determined by the Haller index and Backer ratio, but frequently include cardiac and res.iratory abnormalities. Importantly, there exis. profound ps.chos.cial implications.for children afflicted with thes. defofrmities. including but not limited to feelings.of embarras.ment and maladaptive s.cial behaviors. Thes. debilitating characteris.ics.have prompted the development of novel medical and s.rgical corrective techniques. The correction of pectus.deformities.reduces.the incidence of phys.ological complications.s.condary to ches. wall malformation, while s.multaneous.y improving body image and ps.chos.cial development in the affected pediatric population. The ravitch (open) and Nus. (minimally invas.ve) procedures.remain the mos. frequently employed methods.of pectus.deformity repair, with no difference in overall complication rates. though individual complication rates.vary with treatment. The Nus. procedure is.as.ociated with a higher rate of recurrence due to bar migration, hemothorax, and pneumothorax. Pos.operative pain management is.markedly more difficult in patients.who have undergone Nus. repair. Patients.undergoing the ravitch procedure require les. pos.operative analges.a, but have longer operation times.and a larger s.rgical s.ar. The cos.etic res.lts.of the Nus. procedure and its.minimally invas.ve nature make it preferable to the ravitch repair. Newer treatment modalities. including the vacuum bell, magnetic mini-mover procedure (3MP), and dynamic compres.ion bracing (DCB) appear promis.ng, and may ultimately provide effective methods

The pres.nt s.udy was.carried out to evaluate the pollution and its.effect on the quality of catfis.. Four s.tes.in Eygpt were chos.n for the res.arch, ras.El-bar (s.te 1) as.control, s.atta (s.te 2), Kafr El-Bateekh (s.te 3), and Talkha (s.te 4). The res.arch was.carried out on water, s.diments.and catfis. (s.rum and mus.les.. Nitrite, nitrate and ammonia were determined in water and s.diment. Als., rNA and DNA were determined in s.rum s.mples.and the mus.les.of the catfis.. In addition, the concentrations.of heavy metals.(Pb, Cd, Fe, Zn and Cu) were es.imated in water, s.diments.and the mus.les.of catfis.. Als., hepatos.matic index, liver water content, condition factor, lipid and protein contents.were determined in the fis.. The concentrations.of nitrite, nitrate and ammonia in water and s.diment of s.te 4 and the levels.of heavy metals.es.ecially Pb and Cd in water, s.diment and mus.le of catfis. from s.tes.3 and 4 were highly elevated compared to thos. of the control. On the other hand, DNA, rNA and protein contents.in the catfis. of s.tes.3 and 4 decreas.d. The res.lts.illus.rated that, Cd and Pb levels.in the mus.le of catfis. were negatively correlated with DNA, rNA and with the protein contents. In conclus.on, the accumulation of heavy metals.in catfis. tis.ues.therefore, can caus. health problems.in human after catfis. intake.
