Objective: discuss and analyze the application effects of nursing risk management in assisted reproductive nursing. Methodology: this research was carried out by selecting 384 IVF-ET (In-vitro fertilization and embryo transfer) patients admitted by certain hospital during February 2016 to February 2018 as research objects, who are classified into general group and research group at random by numbering all randomly, with 192 objects per group for comparing adverse event rate and nursing quality of patients in these two groups. Result: the adverse event rate of patients in research group is 4.17%, while that in general group is 10.94%, with the adverse event rate in research group lower than that in general group (P < 0.05);the overall scores of nursing quality in research group is (96.37±9.37), while that in general group is (79.34±8.25), with the overall score in research group significantly higher than that in general group (P < 0.05);the nursing satisfaction of research group and general group are 95.31% and 84.38% respectively, with the satisfaction in research group significantly higher than that in general group (P < 0.05). Conclusion: in assisted reproductive nursing, the application of nursing risk management plays a critical role, which can not only reduce the adverse event rate, but also effectively improve the nursing quality of patients, as well as improve the nursing satisfaction of patients, thus being proven that nursing risk management shall be widely applied in clinical nursing.

The Chinese government has emphasized innovation as the primary driving force for economic development in the new era.This paper studies the effect of import policy uncertainty(IPU)on the innovation activity of Chinese manufacturing firms.It establishes a simple model to show that the presence of IPU encourages innovation and that a reduction in IPU discourages innovation.It distinguishes the almost unnoticed IPU reduction from tariff reduction on China's WTO accession and develops a novel difference-in-differences specification that identifies the negative effect of IPU reduction on innovation using updated data for Chinese manufacturing and patent filings.The result holds after a battery of identification assumptions and robustness checks are considered.The import channel explains about two thirds of the effect of IPU on innovation,but not all of the effect.Finally,this paper examines the effect across firms of different levels of productivity and ownership types and patents of different categories.

我国刑法对网络服务提供者施加了一系列积极义务,体现的是国家重视网络空间治理和刑法对网络共治原则的强化,在当下不失为一种理性选择。但积极义务的违反并不具备刑法惩罚的当然性,国家有必要维护规范体系有序而合理的组合关系,避免将犯罪化作为塑造公民责任感的手段,合作义务的泛化及其带来的执法权限下放是存在法治风险的解决办法。我国未来信息网络犯罪治理的关键在于协同治理,在刑法领域,对积极义务的设定有必要秉持最小化的理念;在社会政策的整体性方面,需要国家妥善处理刑法与其他社会政策的有效合作。

The tree ring has been regarded as an emerging archive to reconstruct historical atmospheric mercury(Hg)trends,but with the large knowledge gaps in the reliability.In this study,we comprehensively evaluated the Hg source,radial translocation and age effect of Masson pine(Pinus massoniana)tree ring at Mt.Jinyun in Chongqing,to assess the suitability of such tree ring as the archive of atmospheric Hg.Results showed that distinct variabilities among Masson pine tree-ring Hg concentration profiles.The Hg concentration significantly increased along with stem height(P<0.05),indicating the Hg in tree rings mainly derived from foliage uptake atmospheric Hg.We found a distinct age effect that the tree ring of young trees had the higher Hg concentration.Besides,we used the advection-diffusion model to demonstrate how Hg concentration shifted by the advection or/and diffusion in tree rings.The modeling results showed that the advection induced radial translocation during the young growth period of tree was a plausible mechanism to result in the tree-ring Hg record largely different from the trend of anthropogenic Hg emissions in Chongqing.We finally suggest that in further Hg dendrochemistry,better discarding the tree-ring Hg profile of the young growth period to reduce impacts of the radial translocation and age effect.

Anammox is widely considered as the most cost-effective and sustainable process for nitrogen removal.However,how to achieve the enrichment of anammox biomass remains a challenge for its large-scale application,especially in mainstream wastewater treatment.In this study,the feasibility of enrichment of anammox biomass was explored through the realization of partial denitrification and the addition of bio-carriers.By using ordinary activated sludge,a sequencing batch reactor(SBR)followed by an up-fow anaerobic sludge bed(UASB)was operated at 25±2℃ for 214 days.The long-term operation was divided into five phases,in which SBR and UASB were started-up in Phases I and II,respectively.By eliminating oxygen and adjusting the infow ratios in Phases III-V,advanced nitrogen removal was achieved with the effuent total nitrogen being 4.7 mg/L and the nitrogen removal efficiency being 90.5%in Phase V.Both in-situ and ex-situ activity tests demonstrated the occurrence of partial denitrification and anammox.Moreover,16S rRNA high-throughput sequencing analysis revealed that Candidatus Brocadia was enriched from below the detection limit to in biofilms(0.4%in SBR,2.2%in UASB)and the foc sludge(0.2%in SBR,1.3%in UASB),while Thauera was mainly detected in the foc sludge(8.1%in SBR,8.8%in UASB),which might play a key role in partial denitrification.Overall,this study provides a novel strategy to enrich anammox biomass driven by rapid achievement of partial denitrification through the addition of bio-carriers,which will improve large-scale application of anammox processes in mainstream wastewater treatment.

Water fluoride pollution has caused non-negligible harm to the environment and humans,and thus it is crucial to find a suitable treatment technology.In this study,La-Fe@PTA adsorbent was synthesized for the defluoridation of mine water.The results showed that the optimum conditions for defluoridation by La-Fe@PTA were p H close to 7.0,the initial F-concentration of 10 mg/L,the dosage of 0.5 g/L and the adsorption time of 240 min.Compared with SO_4^(2-),Cl^(-),NO_(3)^(-),Ca^(2+)and Mg^(2+),CO_(3)^(2-)and HCO_(3)^(-)presented severer inhibition on fluoride uptake by La-Fe@PTA.The adsorption process fits well with the pseudo-second-order kinetic model and Freundlich model,and the maximum adsorption capacity of Langmuir model was 95 mg/g.Fixed-bed adsorption results indicated that fluoride in practical fluorinated mine water could be effectively removed from 3.6 mg/L to less than 1.5 mg/L within130 bed volume(BV)by using 1.5 g La-Fe@PTA.Furthermore,the adsorbent still had good adsorption capacity after regeneration,which confirms the great application potential of La-Fe@PTA as a fluoride ion adsorbent.The mechanism analysis showed that La-Fe@PTA adsorption of fluorine ions is a physicochemical reaction driven by electrostatic attraction and ion exchange.

Benefitting from narrow beam divergence,photonic crystal surface-emitting lasers are expected to play an essential role in the ever-growing fields of optical communication and light detection and ranging.Lasers operating with 1.55μm wavelengths have attracted particular attention due to their minimum fiber loss and high eye-safe threshold.However,high interband absorption significantly decreases their performance at this 1.55μm wavelength.Therefore,stronger optical feedback is needed to reduce their threshold and thus improve the output power.Toward this goal,photonic-crystal resonators with deep holes and high dielectric contrast are often used.Nevertheless,the relevant techniques for high-contrast photonic crystals inevitably complicate fabrication and reduce the final yield.In this paper,we demonstrate the first continuous-wave operation of 1.55μm photonic-crystal surface-emitting lasers by using a‘triple-lattice photonic-crystal resonator’,which superimposes three lattice point groups to increase the strength of in-plane optical feedback.Using this geometry,the in-plane 180°coupling can be enhanced threefold compared to the normal single-lattice structure.Detailed theoretical and experimental investigations demonstrate the much lower threshold current density of this structure compared to‘single-lattice’and‘double-lattice’photonic-crystal resonators,verifying our design principles.Our findings provide a new strategy for photonic crystal laser miniaturization,which is crucial for realizing their use in future high-speed applications.
