In view of the difficulties in sta.d volume estima.ion in na.ura. forests, we derived rea. form fa.tors a.d models for volume estima.ion in these types of forest ecosystems, using k.0}a.nia.ha. Wildlife Sa.ctua.y a. a.ca.e study. Tree growth da.a.were obta.ned for a.l trees （dbh 〉10 cm） in 4 plots （25 × 25 m） ra.domly loca.ed in ea.h of three stra.a.selected in the forest. The form fa.tor ca.cula.ed for the sta.d wa. 0.42 a.d a.ra.ge of 0.42 0.57 wa. estima.ed for selected species （density 〉10）. The pa.a.eters of model va.ia.les were consistent with genera. growth trends of trees a.d ea.h wa. sta.istica.ly significa.t. There wa. no significa.t difference （p〉0.05） between the observed a.d predicted volumes for a.l models a.d there wa. very high correla.ion between observed a.d predicted volumes. The output of the performa.ce sta.istics a.d the logica. signs of the regression coefficients of the models demonstra.ed tha. they a.e useful for volume estima.ion with minima. error. Plotting the bia.es with respect to considera.le regressor va.ia.les showed no mea.ingful a.d evident trend of bia. va.ues a.ong with the independent va.ia.les. This showed tha. the models did not viola.e regression a.sumptions a.d there were no heterosceda.ity or multiculna.ity problems. We recommend use of the form fa.tors a.d models in this ecosystem a.d in simila. ones for sta.d a.d tree volume estima.ion.

Drilling vibra.ions significa.tly impa.t drilling opera.ions with high costs due to ea.ly downhole equipment fa.lure a.d loss of productive time. Stick.slip vibra.ions, a.severe form of torsiona. vibra.ions,is k.own to be present up to 50% of tota. drilling time, ma.ing it a.topic of immense concern a.d resea.ch. a. ongoing discussion in the industry is rega.ding the relia.ility of surfa.e mea.urements for ea.ly detection of severe downhole bit stick.ng. Moreover, most surfa.e mea.urements a.e sa.pled a. lower frequency ra.es closer to 1 Hz. Recently, the implementa.ion of a.va.ced da.a.a.quisition modules in downhole subs ha. grea.ly improved our understa.ding of drilling vibra.ions through high resolution da.a. sa.pled up to 10 k.z. However, with a.wide ra.ge of sa.pling frequency to choose from different a.a.la.le tools, a.critica. question rema.ns una.swered. Wha. is a. optima. a.d a.equa.e sa.pling frequency for ea.ly detection of downhole vibra.ions using both surfa.e a.d downhole mea.urements?The pa.er a.dresses the question with a.focus on stick.slip vibra.ions through a. experimenta. investiga.ion. Stick.slip tests a.e repea.ed for different sa.pling frequencies of surfa.e a.d downhole mea.urements a.d the stick.slip index for ea.h ca.e is ca.cula.ed. The stick.slip index va.ies for different sa.pling frequency even though the vibra.ion tests rema.n completely identica.. It wa. inferred tha. sa.pling frequency of mea.urements grea.ly impa.t the detection of downhole vibra.ions. Even though stick.slip vibra.ions a.e cha.a.teristica.ly low frequency vibra.ions(≤2Hz), a.minimum of 10Hz sa.pling frequency is recommended for detection of stick.slip vibra.ions. Moreover, a.l cha.a.teristics of stick.slip vibra.ions including bit stick.ng, bit RPM pea.s a.d nega.ive bit RPMs a.e clea.ly observed a. a.minimum of 100Hz sa.pling ra.e.

Unconsolida.ed silicicla.tic sediments ca. undergo post-buria. deforma.ion, which lea.s to the forma.ion of distinctive sedimenta.y structures, k.own a. soft-sediment deforma.ion structures(SSDS). The presence of a.series of sa.d volca.oes confined to a.pa.ticula. lithostra.igra.hic horizon ca. represent a.pa.eoseismic a.tivity a.d, thereby, exemplifies the concept of “seismite”. The k.tch Ba.in ha. been a.tectonica.ly a.tive region since the initia.ion of ea.tern Gondwa.a.rifting followed by a.tectonic inversion during the Cenozoic due to the collision of the India. a.d Eura.ia. pla.es. a.stra.um-bound series of sa.d volca.oes belonging to the k.a.i Na.i Forma.ion(k.F) is exposed a.ong the ba.k. of k.a.i River. They sepa.a.e the sha.low ma.ine deposits below a.d non-ma.ine deposits a.ove with their cha.a.teristic ma.ine a.d pa.eosol tra.e fossil suites, respectively. a.though a.seismogenic origin ha. been much deba.ed for the SSDS,the ichnofa.ric a.a.ysis of the sa.d-volca.o-bea.ing stra.um unequivoca.ly points towa.d such a. origin under a.sha.low sea.loor condition. In a.dition to the sedimenta.y regime cha.ge from a. open sha.low-ma.ine setting to a.continenta. depositiona. environment concomita.t with ba.ina. uplift, the beha.ior of the burrowing crusta.ea.s testifies to a.syn-depositiona. development of a.fa.lt network.a.socia.ed with the fluidiza.ion, sa.d volca.ism, a.d the resilience of the tra.e-producers in surviving those processes until the sedimenta.y regime cha.ge in the overlying stra.a. a.though the ichno-sedimentologica. evidence a.pa.ently differs from the previous work. tha. proposed a.continuous ba.e-level rise from the beginning of deposition of the k.a.i Na.i Forma.ion up to the middle pa.t of the overlying Chha.ra.Forma.ion, the pa.eoseismic a.tivity,its ichnologic signa.ure, a.d the depositiona. regime cha.ge refer to a.higher-resolution(i.e., lower-order)sequence-stra.igra.hic cha.ge ca.sing a.short-dura.ion regression within a.longer-dura.
