Investigation of the Effect of the Force Arm on the Bending Capability of Prestressed Glulam Beam

Prestress enables the Glulam beam could make full use of the compression strength,and then increase the span,but it still could not reduce all drawbacks,such as cross-section weakening and small force arm.To avoid slotting and ensure suitable tension and compression couple,one kind of novel anchor has been proposed,which could meet the bearing capacity requirement.And then the bending test of prestressed Glulam beams with a geometric scale ratio of 1:2 was simulated,to investigate the effect of the force arm on bending capacities,failure modes,and deformation performance.Results show that increasing the force arm could improve the ultimate bending per-formance of the beam significantly,and the anchor arm length has a certain effect on the performance,but it is not obvious.Finally,based on Finite element method analysis,the practice design suggestions have been offered.

The Swiss Public Opinion Towards the Tasks of the Swiss Armed Forces and the Constitutional Role

After the Cold War, all European armed forces have transformed to be prepared for the new geopolitical environment and have taken new tasks. Since then, the European armed forces are more active in international conflict management. Whereas most of the European states have suspended the conscription, the Swiss Armed Forces still hold on conscription. However, the Swiss Armed Forces have changed also. The reform ＂Armee 95＂ in 1995 and the reform ＂Armee XXI＂ in 2004 have transformed the Swiss Armed Forces and extended their range of tasks. Which of these tasks are legitimated by the Swiss population？ To answer this question, the Swiss population had been interviewed about the tasks of the Swiss Armed Forces as part of the study ＂Sicherheit 2016＂. The tasks which the Swiss population mentioned are displayed in this paper with regard to the transformation process classified and discussed. The evaluation shows that 93% of the interviewees have named one of Switzerland＇s constitutional duties （defense, support of the civilian authorities, and promotion of peace within an international context） as the most important task of the Swiss Armed Forces. Mainly the national defense order and the subsidiary support of the civilian authorities are approved by the Swiss population.

Nocturnal sentry duty and cardiometabolic characteristics in armed forces personnel

BACKGROUND Sleep deprivation can lead to increased body weight and blood pressure(BP),but the latent effects of partial sleep deprivation related to required night sentry duties within a short-term period on cardiometabolic characteristic changes in military personnel are unclear.AIM To investigate the association between night sentry duty frequency in the past 3 months and cardiometabolic characteristics in armed forces personnel.METHODS A total of 867 armed forces personnel who were aged 18-39 years and did not take any antihypertensive medications in Taiwan in 2020 were included.The frequency of night sentry duty was self-reported via a questionnaire(average number of night sentry shifts per month for the past 3 months).Hemodynamic status was assessed via the resting BP and pulse rate(PR).Cardiometabolic risk factors were defined according to the International Diabetes Federation criteria.Multivariable linear regression analyses of the associations between night sentry duties and PR,BP,and other metabolic syndrome(MetS)marker levels were performed,with adjustments for age,sex,substance use,body mass index and aerobic fitness.Multiple logistic regression analysis was carried out to determine the associations between night sentry duties and the prevalence of each MetS feature.

The Influence of the Gentry on Rural Political Construction

Based on some former studies of Chinese rural society, this paper summerizes the achievements and limitations of general Chinese rural studies and then proposes a social operation model in rural areas which is dominated by the squires. It uses some specific historical data and discoveries of feild sduty to further examine the profound influence of the squires on rural politcal construction in three different aspects： the model of clan and religion, the role as inter-mediator and the growth of basic armed forces. The study found that this special social group played a center role in Chinese rural political system from ancient to modem times, particularly, the research considers the decline of the squire society since the establishment of the new government in 1949. In the end, this paper points out the cultural guiding significance of this social model in the study to the rural construction in contemporay China by predicting the possiblity of renaissance

China to Unleash Market Forces in Arms Sector

China is mulling policies to restructure most of its defense industry into shareholding companies, a move that would invite private investment and introduce good corporate governance practices
