Physical activity promotion as intersectoral planning in Milan Health Protection Agency

Abstract Issue/problem Physical activity is a protective factor for preventing Noncommunicable diseases (NCDs) and, for this reason, it plays an important role in all the different guidelines for prevention and health promotion. The Italian Regional Prevention Plans and in particular the Lombardy one promote physical activity with a systemic approach, through both upstream and downstream actions to encourage the role of communities. Description of the problem Based on the regional plan, the Health Protection Agency (HPA) of the Metropolitan City of Milan developed locally validated actions and best practices for the promotion of physical activity, through the cross-sectoral involvement of different stakeholders (health system, companies, universities, local authorities, sports associations, etc.). Results Physical activity is embedded in all lines of health promotion activities in local planning documents. Sustainable and active mobility activities have been implemented in companies and schools with a comprehensive approach. Validated regional programs (Pedibus, Walking Groups, ecc.) have been implemented in the local community, along with the construction of permanent local laboratories for physical activity, structured through the development of specific territorial networks and providing for integration with the socio-sanitary setting. Lessons Promoting physical activity becomes an opportunity to both consolidate territorial networks and to develop evidence-based health promotion actions able to meet the different health needs of the population and to produce a structural change in living contexts. Key messages • Physical activity is both a protective factor for health promotion and a tool for implementing intersectoral and equity-oriented system actions from a life-course perspective. • Promoting physical activity becomes an opportunity to consolidate territorial networks.

Seismic isolation systems for next-generation gravitational wave detectors

Gravitational Wave (GW) Astronomy is becoming a revolutionary method for studying the Universe and understanding its evolution, opening a new frontier in the exploration of cosmic phenomena. Third-generation ground-based gravitational wave interferometers, expected to be built around 2035, will be an order of magnitude more sensitive than the current detectors. Their low frequency sensitivity will allow the detection of binary compact coalescences up to high red-shift improving the capability to study intermediate-mass black holes and enhancing early alerts of binary neutron star coalescences. Within this scientific contest an important effort is being made to increase the detection capabilities in a frequency range down to 3 Hz and mitigating low-frequency noise. The Superattenuator is the mechanical device designed to isolate the optical components of the Advanced VIRGO (AdV) interferometer from seismic noise and local disturbances, relying on the passive and active action of the elements. In this short note, we summarize the design activity around new generation of seismic attenuation systems with the intent to improve the sensitivity in the low frequencies region. The optimization of prototypes and their passive attenuation performance is also considered in view of the Einstein Telescope with the possibility to decrease the size of the mechanical structure and minimizing the impact on the civil works for the construction of the underground laboratory.

Variasi Sistem Pembayaran Terhadap Cash Flow (Studi Kasus : Pembangunan Laboratorium Terpadu AKN Blitar)

Construction projects are a form of long-term investment that requires large capital. One important aspect in construction projects is the payment system. Therefore, it is necessary to vary the payment system on the cash flow of construction projects to determine the effect of the payment variation system on the safest cash flow for the contractor. In this research, the case study used for the calculation of payment system variations on cash flow is the AKN Putra Sang Fajar Blitar integrated laboratory construction project. The payment system used is the progress term payment system. The method used to obtain these results is done by varying the down payment and work progress. There are 6 variations (V) used, namely V1 down payment (0%) work progress 20%, V2 down payment (0%) work progress 25%, V3 down payment 10% work progress 10%, V4 down payment 10% work progress 25%, V5 down payment 20% work progress 20%, V6 down payment 20% work progress 25%. From the results that have been obtained, the highest peak overdraft is in V2 amounting to -Rp5,365,573,659.76 and the lowest is in V3 amounting to -Rp2,864,421,825.56. Meanwhile, the final overdraft value is the same in each variation, which is Rp824,863,740.58. Therefore, the safest variation is V3 with the lowest peak overdraft. The effect of the variation of the payment system that has been known is that the greater the down payment in each variation, the lower the peak overdraft, as well as the smaller the work progress term, the lower the peak overdraft.

Study of the Prediction of Vibrations in Soft Soil Foundations Based on Field Tests.

To explore the prediction of vibrations in soft soil foundations, in light of the construction of laboratories with microvibration requirements on soft soil foundations which are subject to the limitations of urban land planning, field testing was conducted, and the soil surface vibration responses were recorded at different distances from a road under various highway traffic loads. By analyzing the data which summarize the characteristics of soft soil foundations, it is clarified that the vibration response of soft soil foundations mainly occurs at low frequencies, and the vibration response under road traffic loads is prone to resonance at the natural frequency of soft soil foundations. Subsequently, a new vibration prediction method based on the vibration transmission ratio is proposed, and its effectiveness and accuracy based on transmissibility are verified. This research study provides a reference for laboratories constructed on soft soil and for surrounding traffic planning.

From design and construction to operation of the APPLE undulator at TPS

Abstract The APPLE type of Elliptically Polarized Undulator (EPU) not only serves as a crucial circularly polarized light source in existing accelerator facilities but also acts as a standard light source for soft X-rays at the Taiwan Photon Source (TPS). Up to the present, we have autonomously designed, constructed, and operated various EPU configurations. The experience gleaned from the construction of various designs and the choice of material will be outlined in this paper. We also elaborate upon the actions taken to address the adverse effects on the magnetic fields due to the characteristics of non-identical magnets and mechanical deformation. In particular, a method for correction of discrepancies in the magnetic field of the EPU with operation in numerous phase modes employing iron shims is described. In addition, we also discuss the adverse effects on the storage ring that must be dealt with for stable operation of the EPU at the TPS and optimization of the magnetic field during the laboratory construction phase. This paper will further explain management issues related to the susceptibility of the EPU to radiation damage. The comprehensive experience related to the EPU at the TPS, from design and construction to operation will be presented in this paper.

Estimation of the Physical Progress of Work Using UAV and BIM in Construction Projects

The delay in the physical progress of construction creates additional costs, missed deadlines, and quality issues. The research aimed to estimate the physical progress of the project by using unmanned aerial vehicles (UAVs) and building information modeling (BIM). The methodology comprised capturing 848 high-resolution images of the Civil Engineering Laboratory construction site at the National University of Jaen, Cajamarca, Peru, using the Phantom 4 RTK drone. The photographs were processed using Agisoft 2.0.1 software, resulting in a point cloud. This was then imported into ReCap Pro 2023 software, which was used to assess the quality of the points. The Revit 2023 software was subsequently utilized to establish the phase parameters, linking the BIM model with the point cloud, filtering the model, and eventually exporting it to the Power BI 2023 software. The work's estimated progress utilizing the proposed methodology was 42.82%, which was not statistically significant compared to the Public Works Information System (INFOBRAS) of 43.14%. This allows for the automation of customary processes, the identification of crucial issues, and prompt decision-making. The study's originality lies in the suggestion of integrating aerial imagery with drones and BIM modeling for the real-time and precise estimation of work progression. This method provides a precise and effective substitute for traditional techniques for gauging the tangible advancement of projects. Doi: 10.28991/CEJ-2024-010-02-02 Full Text: PDF

Evaluation of EDZ characterization technology for URL based on field investigation at BET

Detailed characterization of the Excavation Damage Zone (EDZ) is an important issue for the high-level radioactive waste (HLW) geological disposal engineering, which is closely related to the long-term safety of the HLW repository. With drill-blast experiment in Beishan Exploration Tunnel (BET, a platform for the field experiment and validation of potential technologies used for China’s HLW disposal engineering in crystalline rock), systematic field tests were carried out to evaluate the suitability of techniques in characterizing EDZ, and to study EDZ characteristic in crystalline tunnel. A series of investigation technologies were used to delineate EDZ and to examine the process of its formation, which includes: p-wave velocity measurement, ground penetrating radar (GPR), acoustic emission (AE) monitoring and borehole televiewer. P-wave velocity measurement along borehole reveal that wave velocity decreased significantly (more than 10%) in 30 cm to 50 cm from the excavation surface, and this zone is defined as EDZ. Clear images of borehole televiewer were obtained, which is helpful for EDZ delineation. GPR and borehole radar were also used for EDZ delineation. Strong reflection signals were detected in the range of 10 cm to 25 cm by GPR with high frequency antenna, indicating significant changes of physical properties of rock-mass in the zone, which is defined as Highly Damaged Zone (HDZ). Moreover, the formation process of EDZ induced by blast in crystalline rock tunnel was analyzed using AE monitoring. Damage process of surrounding rock was divided into blasting damage stage and progressive damage stage. AE events location show the induced cracking activities were clustering within 30 cm to 100 cm from excavation surface. With the experience from field investigation and result analysis, the feasibility and suitability of the techniques for EDZ characterization is evaluated. Finally a specialized EDZ characterization technique system is proposed for underground research laboratory construction in crystalline host rock in Beishan area.

Laboratory performance and construction challenges for plant produced asphalt mixes containing RAP and RAS

In this study, four plant-produced asphalt mixes were considered to evaluate the performance and construction challenges of mixes containing RAP/RAS. Also, asphalt mixes were collected at two different plant-production times for each mix type to monitor the performance variability between lots. A softer base binder (PG 58–22) was used for mixes with RAS compared to the base binder (PG 64–16) used for the control mix (no RAP or RAS) and the mix with only RAP. Use of small dosages of rejuvenators and the softer binder in the RAS mixes were found to show similar performance compared to the control mix with no RAP or RAS. The results obtained from the extracted binders of these mixes indicate that mixes with RAP and RAP/RAS are expected to show higher rutting resistance and slightly lower low-temperature cracking resistance, also shown in the mix rutting and fracture cracking tests. A similar fatigue life was observed for all mixes at low strain levels in the Four-Point Beam test. However, the mix with both RAP and RAS was found to show better fatigue life at high strain levels. Similar performance test results were observed between different lots of the same mix type for most cases. Finally, there were no problems with field mixing, compaction, or finishing of the mixes containing RAP and RAP/RAS.

Female meiotic drive shapes the distribution of rare inversion polymorphisms in Drosophila melanogaster.

In all species, new chromosomal inversions are constantly being formed by spontaneous rearrangement and then stochastically eliminated from natural populations. In Drosophila, when new chromosomal inversions overlap with a pre-existing inversion in the population, their rate of elimination becomes a function of the relative size, position, and linkage phase of the gene rearrangements. These altered dynamics result from complex meiotic behavior wherein overlapping inversions generate asymmetric dyads that cause both meiotic drive/drag and segmental aneuploidy. In this context, patterns in rare inversion polymorphisms of a natural population can be modeled from the fundamental genetic processes of forming asymmetric dyads via crossing-over in meiosis I and preferential segregation from asymmetric dyads in meiosis II. Here, a mathematical model of crossover-dependent female meiotic drive is developed and parameterized with published experimental data from Drosophila melanogaster laboratory constructs. This mechanism is demonstrated to favor smaller, distal inversions and accelerate the elimination of larger, proximal inversions. Simulated sampling experiments indicate that the paracentric inversions directly observed in natural population surveys of Drosophila melanogaster are a biased subset that both maximizes meiotic drive and minimizes the frequency of lethal zygotes caused by this cytogenetic mechanism. Incorporating this form of selection into a population genetic model accurately predicts the shift in relative size, position, and linkage phase for rare inversions found in this species. The model and analysis presented here suggest that this weak form of female meiotic drive is an important process influencing the genomic distribution of rare inversion polymorphisms.

Chinese expert consensus on the construction of the fluoroless cardiac electrophysiology laboratory and related techniques.

Transcatheter radiofrequency ablation has been widely introduced for the treatment of tachyarrhythmias. The demand for catheter ablation continues to grow rapidly as the level of recommendation for catheter ablation. Traditional catheter ablation is performed under the guidance of X-rays. X-rays can help display the heart contour and catheter position, but the radiobiological effects caused by ionizing radiation and the occupational injuries worn caused by medical staff wearing heavy protective equipment cannot be ignored. Three-dimensional mapping system and intracardiac echocardiography can provide detailed anatomical and electrical information during cardiac electrophysiological study and ablation procedure, and can also greatly reduce or avoid the use of X-rays. In recent years, fluoroless catheter ablation technique has been well demonstrated for most arrhythmic diseases. Several centers have reported performing procedures in a purposefully designed fluoroless electrophysiology catheterization laboratory (EP Lab) without fixed digital subtraction angiography equipment. In view of the lack of relevant standardized configurations and operating procedures, this expert task force has written this consensus statement in combination with relevant research and experience from China and abroad, with the aim of providing guidance for hospitals (institutions) and physicians intending to build a fluoroless cardiac EP Lab, implement relevant technologies, promote the standardized construction of the fluoroless cardiac EP Lab.

Exploring the model of laboratory construction and optimization to promote the transformation of research results in the context of big data

Abstract Scientific research results represent a country’s innovation capability. To previous statistics, the scientific research results of Chinese university laboratories are more focused on the basic research stage, while the industrialization and commercialization stages of the results are often broken. In this paper, by using the DEA model to determine the relationship between input and output, decision unit, and efficiency variables, the input-output indexes are selected for the calculation to obtain the comprehensive efficiency, pure technical efficiency, and scale efficiency of the transformation of scientific research results in university laboratories; subsequently, the output slack variables of non-DEA validity decision unit are analyzed differently. The results show a 63.41% difference between the maximum comprehensive efficiency value and the minimum value of the transformation of scientific research results in 30 universities, and the slack variable variance analysis reveals that there is 42.27% input redundancy and 31.87% output deficiency in 30 universities. This paper improves the conversion rate of laboratory scientific research results based on the improvement of input and output indicators from the decision-making level; and proposes the tripartite collaboration model of laboratories governments, and enterprises, which promotes the acceleration of scientific research results into the market and the industrialization of scientific research results.
