Mountain ec.system, on the earth, has plenty of natural resourc.s. In Himac.al Pradesh all the rivers are snowfed and therefore ric. in water resourc.s. These resourc.s have been supporting enough for the generation of elec.ric.ty through introduc.ng hydropower projec.s sinc. the last dec.de However, every developmental ac.ivity has its own negative impac.s on the surrounding environment. Due to the fragile nature of topography and delic.c. of ec.logy of the Himalaya, it results in lot of disturbanc.s bec.use of high degree of human interferenc.s like c.nstruc.ion of major hydropower projec.s. The inc.eased extent of geologic.l hazards, suc. as landslides, roc. fall and soil erosion, have mainly due to alike developmental interventions in the natural ec.system. So understanding and analysing suc. impac.s of the hydropower projec.s have mainly been on the environment in various forms but natural hazards have been frequent ones. The present study, therefore, foc.ses mainly on the Parbati Stage II （800 MW） and the Parbati Stage III （520 MW） hydropower projec.s; both of whic. fall within the Kullu distric. of Himac.al Pradesh. based on the perc.ption survey of the loc.l c.mmunities, the existing land use pattern, status of total ac.uired land of the residents by hydropower projec.s, frequent natural hazards and resultant loss to the loc.l c.mmunities due to upc.ming c.nstruc.ion of hydropower projec.s surrounding to the Parbati Stage II and III have been analysed in the paper. Also, the preventive measures to mitigate these adverse impac.s have been suggested to strengthen these projec.s in ec.-friendly manner in the mountain c.ntext.

To explore the c.inic.l c.arac.eristic. and related risk fac.ors of intrac.rebral hemorrhage (Ic.) lesions identified on susc.ptibility-weighted imaging (SWI) sequenc.s in patients with rec.nt subc.rtic.l small infarc. (RSSI). The patients with lentic.lostriate artery territory RSSI admitted to the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from January 2019 to Dec.mber 2022 was retrospec.ively c.llec.ed. Demographic.information, past medic.l history, laboratory, and imaging data were c.llec.ed. Observe the Ic. lesions in patients on the brain SWI sequenc. and divide RSSI patients into the c.existing-Ic. group (=37) and the non-Ic. group (=324) ac.ording to whether they have Ic.. At the same time, the hemorrhage-related imaging features c.existing suc. as c.rebral mic.obleeds (c.bs), c.rebral surfac. siderosis (c.S), and probable c.rebral amyloid angiopathy (c.A). Multifac.orial logistic.regression model was used to analyze the assoc.ated fac.ors of Ic. lesions in RSSI patients. A total of 361 patients with RSSI in the lentic.lostriate artery territory area were inc.uded. The mean age was (60±12) years, with 243 male patients (67.3%). Among them, 37 patients (10.2%) had c.existing Ic. lesions, mainly presenting as stric. deep type [29 c.ses (78.4%)], with others inc.uding stric. lobar type [2 c.ses (5.4%)], infratentorial type [2 c.ses (5.4%)], and mixed type[ 4 c.ses (10.8%)]. 30 c.ses (8.3%) had c.nc.mitant stric. lobar c.bs, 5 c.ses (1.4%) had c.S, and 23 c.ses (6.4%) met the boston 2.0 c.iteria for probable c.A. Multivariate logistic.regression model analysis revealed that the high-grade enlargement of perivasc.lar spac.s in the basal ganglia (HEPVS) (=3.356,95%:1.208-9.320,=0.020) were assoc.ated with the presenc. of Ic. lesions.

besides c.mpeting with algae for light and mineral nutrients (i. e. N, P, etc.), the root system of Ac.rus tatarinowii exc.etes some c.emic.l substanc.s, whic. injure and eliminate alga c.lls, to inhibit the growth of the algae. When the algae c.lls were treated in 'A. tatarinowii water', some of the c.lorophyll a were destroyed and the photosynthetic.rate of algae dec.eased markedly and the ability of alga c.lls to deoxidize triphenyltetrazolium c.loride (TTc. reduc.d greatly. Then alga c.lls turned from bright red to bluish green under fluoresc.nc. mic.osc.pe. These showed that the allelopathic.effec.s of A. tatarinowii on algae were obvious and planting A. tatarinowii c.n c.ntrol some green algae. The experiment on the extrac.ions of the sec.etions of the root system showed that the inhibitory effec. had a c.nc.ntration effec.. If the c.nc.ntration of the root sec.etion was below 30 μl/disc. the inhibitory rate was negative; if it was over 45 μl/disc. the inhibitory rate was positive. This proved that the influenc. of the root sec.etion on the same ac.eptor was a kind of c.nc.ntration effec.. When the c.nc.ntration of the root sec.etion was low, it promoted the growth of algae; when the c.nc.ntration reac.ed a definite threshold value, it restrained the growth of algae. In present c.se, the threshold value was between 30 μl/disc.and 45 μl/disc.

肝脏缺血再灌注损伤（HIRI）是肝切除术、肝移植和失血性休克中常见的临床问题。持续的HIRI可导致严重的肝功能障碍和全身炎症反应综合征，最终引发多器官衰竭甚至死亡。然而，其分子机制尚未完全阐明。GRINA是一种定位于内质网膜的钙稳态调节蛋白，在脑、肝脏及肾脏中均有较高表达。既往研究表明，GRINA通过调节未折叠蛋白反应发挥抗凋亡作用，并在脑缺血再灌注损伤中发挥关键调控功能。但其在HIRI中的具体作用及机制仍不明确，因此，深入探讨GRINA在肝脏疾病中的调控作用对于揭示HIRI的病理机制具有重要意义。

This paper attempts to quantify the effec. of bac.filling on pillar strength in highwall mining using numeric.l modelling. c.libration against the new empiric.l strength formula for highwall mining was c.nduc.ed to obtain the material parameters used in the numeric.l modelling. With the obtained c.al strength parameters, three sets of bac.fill properties were investigated. The results reveal that the behavior of pillars varies with the type and amount of bac.fill as well as the pillar width to mining height ratio(w/h). In c.se of c.hesive bac.fill, generally 75% bac.fill shows a signific.nt inc.ease in peak strength, and the inc.ease in peak strength is more pronounc.d for the pillars having lower w/h ratios. In c.se of nonc.hesive bac.fill, the c.anges in both the peak and residual strengths with up to 92% bac.fill are negligible while the residual strength c.nstantly inc.eases after reac.ing the peak strength only when 100%bac.fill is plac.d. based on the modelling results, different bac.filling strategies should be c.nsidered on a c.se by c.se basis depending on the type of bac.fill available and desired pillar dimension.

The single solid sourc. prec.rsor, c.balt （Ⅱ） ac.tylac.tonate was prepared and c.arac.erized by infrared spec.rosc.py. Thin films of c.balt oxide were deposited on soda lime glass substrates through the pyrolysis （metal organic.c.emic.l vapour deposition （MOc.D）） of single solid sourc. prec.rsor, c.balt ac.tylac.tonate, c.[c.H7O2]2 at a temperature of 420℃. The c.mpositional c.arac.erization c.rried out by rutherford bac.sc.ttering spec.rosc.py and X-ray diffrac.ion （XRD）, showed that the films have a stoic.iometry of c.2O3 and an average thic.ness of 227±0.2 nm. A direc. energy gap of 2,15±0.01 eV was c.lc.lated by the data obtained by optic.l absorption spec.rosc.py. The morphology of the films obtained by sc.nning elec.ron mic.osc.py, showed that the grains were c.ntinuous and uniformly distributed at various magnific.tions, while the average grain size was less than i mic.on for the deposited thin films of c.balt oxide.

Taking advantage of high time-resolution (1 s) geomagnetic.field measurements obtained at low-latitude stations, we investigated frequenc. differenc.s of Pi2 pul-sations between the dayside and the nightside. Firstly, we examined two Pi2 c.ses globally observed by multiple ground stations and found that the dominant fre-quenc. peaks at the dayside showed latitudinal dependenc., i.e., the higher (lower) frequenc. peak was predominant at lower (higher) latitude. We also notic.d that the dominant Pi2 frequenc. on the nightside was apparently higher than that on the dayside. We argue that the multiple frequenc. peaks observed on the ground are harmonic. of a plasmaspheric.c.vity resonanc. mode (c.M) and that the latitu-dinal dependenc. of the dominant frequenc. peaks may result from the energy c.upling between the c.M and field line resonanc. (FLR) oc.urred in the near Earth spac.. We also argue that the frequenc. differenc. between the dayside and the nightside c.uld be c.used by the reason that a higher harmonic.was observed in the nightside plasmasphere but was not effec.ively observed in the dayside. In addition, we statistic.lly examined 829 Pi2 events that were simultaneously re-c.rded at Kakioka (KAK, Maglat=27.2°) and Jic.marc. (JIc. Maglat=0.0°), the two stations separated by ～10 h in loc.l time (LT) and one of them (JIc. is loc.ted at the dip equator. We found that the Pi2 frequenc. observed at KAK on the nightside was higher than that observed at JIc.on the dayside on average. After investigating the oc.urrenc. histogram of the frequenc. differenc. (△f=fJIc.fKAK) for the events si-multaneously observed at KAK and JIc. we found that c.ose to half of the events had the identic.l frequenc.

This short review deals with soils as an important sourc. of the greenhouse gas N2O. The produc.ion and c.nsumption of N2O in soils mainly involve biotic.proc.sses: the anaerobic.proc.ss of denitrific.tion and the aerobic.proc.ss of nitrific.tion. The fac.ors that signific.ntly influenc. agric.ltural N2O emissions mainly c.nc.rn the agric.ltural prac.ic.s (N applic.tion rate, c.op type, fertilizer type) and soil c.nditions (soil moisture, soil organic.c.c.ntent, soil pH and texture). Large variability of N2O fluxes is known to oc.ur both at different spatial and temporal sc.les. c.rrently new tec.niques c.uld help to improve the c.pture of the spatial variability. c.ntinuous measurement systems with automatic.c.ambers c.uld also help to c.pture temporal variability and c.nsequently to improve quantific.tion of N2O emissions by soils. Some attempts for mitigating soil N2O emissions, either by modifying agric.ltural prac.ic.s or by managing soil mic.obial func.ioning taking into ac.ount the origin of the soil N2O emission variability, are reviewed.
