Th. first Zagreb index M1 （G） is equal to th. sum of squares of th. degrees of th. vertices, and th. second Zagreb index M2 （G） is equal to th. sum of th. products of th. degrees of pairs of adjacent vertices of th. underlying molecular graph.G. In th.s paper, we obtain lower and upper bounds on th. first Zagreb index MI（G） of G in terms of th. number of vertices （n）, number of edges （m）, maximum vertex degree （△）, and minimum vertex degree （δ）. Using th.s result, we find lower and upper bounds on M2（G）. Also, we present lower and upper bounds on M2（G）＋ M2（G） in terms of n, m, △, and δ, wh.re denotes th. complement of G. Moreover, we determine th. bounds on first Zagreb coindex MI（G） and second Zagreb coindex M2（G）. Finally, we give a relation between th. first Zagreb index and th. second Zagreb index of graph.G.

Th. study of exotic structure of h.drons is fully ach.eved wh.n reaction dynamics of th. associated h.dron productions is well understood. We employ as th. standard mech.nism th. effective Lagrangian meth.d and investigate several ph.sical observables with.n th. framework. Th. parameters are constrained by microscopic description of h.drons. We discuss ph.toproductions of kaon associated with.th. ground state A（1116） and its resonances A（1405） and A（1520）. In th. former example we emph.size th. meson cloud effect wh.ch.significantly renormalizes th. ph.nomenological parameters, wh.le in th. latter we discuss th. features of th. standard meth.d. Finally we discuss briefly th. N（1535） for th. study of ch.ral symmetry of baryons. production of ηπ associated with.th. nucleon resonance

A wide variety of processes are being pursued by research.rs for cost effective extraction of titanium metal. Electroch.mical processes are promising due to simplicity and being less capital intensive. Some of th. promising electroch.mical processes of titanium extraction were reviewed and th. results of laboratory scale experiments on electroch.mical reduction of TiO2 granules were brough. out. Some of th. kinetic parameters of th. reduction process were discussed wh.le presenting th. quality improvements ach.eved in th. experimentation.

Th.racoscopic esoph.gectomy is only establish.d in some centers and a?ords a cervical anasto- mosis because intrath.racic anastomosis as a routine is tech.ically too di?cult. Laparoscopic mobilisation of th. stomach.(gastrolysis) is an important contribution for minimal invasive surgery of esoph.geal cancer. Th.s procedure reduces th. stress of th. two cavity operation for th. patient and allows th. construction of a comparable gastric conduit like by open surgery. Th. tech.ique of laparoscopic gastrolysis as prepa- ration for transth.racic en bloc esoph.gectomy is described in detail and preliminary results are brie?y mentioned.
