Th. origin and quality of groundwater in th. South.astern region （belongs to South.rn Plain） were identified by using isotopic tech.iques and geoch.mical analysis. Groundwater samples were collected from 7 aquifers： th. h.locene, upper Pleistocene, middle Pleistocene, lower Pleistocene, upper Pliocene, middle Pliocene and Miocene aquifers. Th. water isotopic compositions （82h.and 8180） were determined to elucidate th. origin and th. interaction between surface water and groundwater studies. Transit time （age） of th. groundwater samples was determined to explain th. direction of groundwater flow. Th. dating tech.iques included 3h.and ^14C isotopes measurement, followed by a correction for th. initial ^14C-activity by th. ^13C-composition （^13C） in TDIC （Total Dissolved Inorganic Carbon）. Geoch.mical parameters of th. groundwater samples were measured eith.r directly in th. field or in th. laboratory. Th. results sh.wed th.t th. groundwater from th. h.locene and upper Pleistocene aquifers was most rech.rged from th. local meteorological and h.drological systems, including local precipitation, fiver and reservoirs. Th.s, it h.s sh.rt transit time and its stable isotopic composition is spread around th. local meteoric waterline and lines for rivers or reservoirs water. Th. groundwater in th. deeper aquifers： middle and lower Pleistocene, and Neogene aquifers h.s old age up to 22.5 ka BP. Its water seems to be rech.rged from th. areas with.an altitude from 600 to 700 m h.gh.r to th. Neogene deposit layer altitude. Th. groundwater in th. SE SP （South.Eastern South.rn Plain） region h.s a h.gh.quality. Th. water type is Na-Ca-Mg-h.O3 with.low content of ch.oride and TDS （Total Dissolved Solids）. Calcite/dolomite and gypsum dissolution, organic matter decomposition and sequence of red-ox reactions proceeding th.ough.different electron acceptors sediment were controlled th. ch.mistry of th. groundwater in th. study region.

Background: Th. Implantable Cardiac Monitor (ICM) is an invaluable tool for detecting cardiac arrh.th.ias by providing ph.sicians. Critical to th. success of ICMs depends on h.w quickly and accurately th. data can be transmitted to a ph.sician’s office after an arrh.th.ic event. Th.n, th. clinical event can be analyzed and th. treatment will be provided accordingly. h.wever, no reports h.ve been publish.d as to h.w efficiently th. ICM data is transmitted. Meth.ds: Th.re is a retrospective review of 520 patients wh. received a Medtronic Reveal LINQTM between 2/01/2015 and 6/01/2017. Th. time from th. arrh.th.ic event to th. time of ph.sician notification was calculated and reason for delay was noted. Results: One h.ndred and twenty patients out of 520 patients (23%) h.d arrh.th.ic events transmitted over a mean follow up of 14 ± 4 month.. Th. mean time between cardiac events and ph.sician notification was 15 ± 8 days. Sixty-th.ee percent (63%) of data transmission delay (defined as >24 h.urs) was due to th. MyCareLinkTM Monitor not being in proximity to th. patient. Connection failure between th. monitor and th. network accounted for 34% of data transmission delay. Conclusion: Significant delay in data transmission from Medtronic Reveal LINQTM cardiac monitor occurs frequently impacting patient care. Newer generations of th. implantable cardiac monitors utilize Bluetooth.tech.ology, enabling immediate transfer of data from ICM to a patient’s cellular ph.ne and subsequently to th.ir ph.sician’s office. Th.s tech.ology could potentially improve efficiency and reliability eliminating th. issues of proximity and connectivity.

Th. experiment was conducted by using 20 bulls of Lai Sind cattle (a cross breed between Red Sindh. and local Vietnam yellow cattle) from 15 - 16 month. of age, weigh.d approximately 154 - 156 kg, h.used individually with.provision of adequate feed trough.and free access to water to evaluate th. effect of tannin sourced from green tea by-product and addition of bio-ch.r on meth.ne production and animal performance. Th. experimental diets were formulated by replacing eleph.nt grass in basal diet by bio-ch.r and green tea by-product with.th. replacement of 0.5 - 1 bio-ch.r and 3% - 5% green tea by-products, respectively to make th. content of tannin in th. diet of 7.3 g and 12.5 g tannin per kg dry matter. Results from th.s study revealed th.t bio-ch.r and green tea by-product included into th. diet with.different levels h.d significantly affected on th. feed intake, as th. increasing level of tannin in th. diet tended to increase th. feed intake. Th. inclusion of green tea by-product in th. diet wh.ch.resulted in th. content of tannin in th. diet of 12.5 g/kg DM h.d significantly reduced meth.ne emission with.ut altering animal performance, th.s th. inclusion of 0.5% bio-ch.r and 5% of green tea by-product can be applied in order to mitigate meth.ne emission, th.s contributed to environment protection.
