In this paper, it was introduced the abbreviated situation of ⅪⅠ World Earthquake engineering Convention (WECC) from 30 Jan to 4 Feb.2000 in Auckland, New Zealand.

Stomatal response to elevated CO2 concentrations was examined by stomatal conductance (gs), ratio of intercellular to ambient CO2 concentration (ci/ca) and stomatal number. Reciprocal transfer experiments of stomatal conductance showed that stomatal conductance in high-[CO2]-grown plants increased in comparison with ambient-[CO2]-grown plants when measured at their respective growth CO2 concentration and at the same measurement CO2 concentration (except a reduction in 700 μmol·mol-1 CO2 grown plants compared with plants on unchambered field when measured at growth CO2 concentration and 350 μmol·mol-1CO2). High-[CO2]-grown plants exhibited lower ci/ca ratios than ambient-[CO2]-grown plants when measured at their respective growth CO2 concentration. However, ci/ca ratios increased for plants grown in high CO2 concentrations compared with control plants when measured at the same CO2 concentration. There was no significant difference in stomatal number per unit long needle between elevated and ambient CO2. However, elevated CO2 concentrations reduced the total stomatal number of whole needle by the decline of stomatal line and changed the allocation pattern of stomata between upper and lower surface of needle.展开更多

It was attended by representatives of 25 countries in the region and resource persons, representatives from WHO and other international agencies. The objectives of the workshop were to review the progress of countries in developing, implementing and monitoring national plans of action for nutrition (NPANs) in the Western Pacific Region and to identify constraints and key elements of success in these efforts. Most of the countries have NPANs, either approved and implemented or awaiting official endorsement. The Plan formulation is usually multisectoral, involving several government ministries, non governmental organizations, and international agencies. Often official adoption or endorsement of the Plan comes from the head of state and cabinet or the minister of health, one to six years from the start of its formulation. The NPAN has stimulated support for the development and implementation of nutrition projects and activities, with comparatively greater involvement of and more support from government ministries, UN agencies and non-governmental agencies compared to local communities, bilateral and private sectors and research and academic institutions. Monitoring and evaluation are important components of NPANs. They are, however, not given high priority and often not built into the plan. The role of an intersectoral coordinating body is considered crucial to a country's nutrition program. Most countries have an intersectoral structure or coordinating body to ensure the proper implementation, monitoring and evaluation of their NPANs. The workshop identified the constraints and key elements of success in each of the four stages of the NPAN process: development, operationalization, implementation, and monitoring and evaluation. Constraints to the NPAN process relate to the political and socioeconomic environment, resource scarcity, control and management processes, and factors related to sustainability. The group's review of NPAN identified successful NPANs as those based on recent, adequate and good quality information on the nutritional situation of the country, and on the selection of strategies, priorities and interventions that are relevant to the country and backed up by adequate resources. Continued high level political commitment, a multisectoral approach, and adequate participation of local communities are other key elements for success. The participants agreed on future actions and support needed from various sources for the further development, implementation, monitoring and evaluation of their NPANs. The recommendations for future actions were categorized into actions pertaining to countries with working NPAN, actions for countries without working NPAN and actions relevant to all countries. There was also a set of suggested actions at the regional level, such as holding of regular regional NPAN evaluation meetings, inclusion of NPAN on the agenda of regional fora by the regional organizations, and strengthening of regional nutrition networks.展开更多

The general case for amplitudes of waves that resulted in doubling of the number of equations is considered. It is shown that the application of the methods of finite differences to the computer simulation of transition regimes is completely consistent with the analytical results found for the asymptotical solutions in form of solitons. The obtained results also indicate that the laser pulses of Gaussian shape appearing at the boundary of nonlinear medium tend to become solitons of Lorentzian shape. It was also found that the formation of solitons occurs when the vibrations of optical phonons and that of electromagnetic wave were either in or out of phase. It is shown that all electromagnetic waves entering the medium with different speeds become solitons having the same speed. In the second part of the paper we considered the computer simulation of soliton stability with respect to small (weak) perturbations of all interacting waves. In the present paper we considered the case of evolution of those disturbances in the vicinity of peaks of solitons. The numerical analysis showed that in wide range of parameters the solitons were stable.展开更多

The heart rate was paced artificial-ly at a constant speed. AMI of the left ventricle was produced by ligature of LVB for 30 min andMAPs recorded from the bonder zone of ischemia with the bipolar epicardial contact electrodes. Thechief findings showed that MAPD<sub>50</sub>, MAPD<sub>90</sub> abbreviated obviously and MRR accelerated apparentlyafter AMI while EA could inhibit the abbreviation of MAPD<sub>50</sub> and MAPD<sub>90</sub>, and delay the accelera-tion of MRR. It suggested that EA might be beneficial to anti-arrhythmia and prevented from sud-denly cardial death. Therefore the result has provided not only a new experimental evidence for an im-portant contribution to coronary heart disease treated with acupuncture but also a new content for therelationship between Neiguan (PC 6) of Pericardium Meridian and the heart.展开更多

文摘The prevalence of unilateral deafness(SSD)or asymmetric hearing loss(AHL)among patients with hearing impairments ranges from 7.2%to 15.0%,indicating a relatively significant proportion.However,these individuals often overlook their hearing loss,resulting in delayed or inadequate treatment.This oversight can lead to a lack of binaural summation and squelch effect,as well as the head shadow effect,which can significantly impact their speech recognition and sound localization abilities,especially in noisy environments.Recently,a groundbreaking Sound Bite™Pinyin® Bone Conduction Hearing Aid(HA)device has been has been introduced as a viable alternative to traditional percutaneous stimulation hearing assistance devices.This innovative device harnesses bone conduction technology to convey sound vibrations directly to the inner ear via the bones of the jaw and skull,effectively bypassing the air conduction pathway that is commonly compromised in individuals with hearing loss.This report details the evaluation and adjustment process of a HA device worn by a 31-year-old female patient who suffers from a congenital ossicular chain deformity in her right ear,while maintaining normal hearing in her left ear.The report comprehensively covers the hearing thresholds of the 31-year-old female patient on the day of fitting the hearing aid and one month later.It also presents assessments of the hearing aid’s performance through the Abbreviated Profile of Hearing Aid Benefit(APHAB)questionnaire,conducted three days after adjustment,one month later,and one year later.Furthermore,the report details the evaluation of the patient’s sound localization ability,comparing her performance before and after wearing the hearing aid device.Additionally,it includes measurements of her speech recognition ability for monosyllabic words and Yang Yang Ge words,which are specific tests in the Chinese language,conducted two years after the initial fitting of the hearing aid.The discovery that bone-anchored hearing devices can significantly enhance hearing thresholds in patients with unilateral conductive hearing loss represents a significant milestone.These devices not only improve speech recognition ability but also enhance sound localization in noisy environments.This improvement is accompanied by a high level of subjective satisfaction among patients,indicating a positive impact on their overall quality of life.
