Based on the constitutions in 193 countries, this paper aims to examine the fundamental situation of incorporating environmental rights into a constitution. It has been concluded that environmental protection as a right is written into a constitution in three aspects, namely, as a constitutional right, a civic duty, and a national policy, principle or social goal. Through summarizing these, this paper argues that including environmental rights in a country’s constitution is the means by which all citizens shall enjoy a good, healthy, sustainable and harmonious environment suitable for their development, have timely and comprehensive access to reliable information about environment, participate in making public decisions related to the environment, and ask for legal remedies and compensation for any infringement on their environmental rights, or injury or damage to their environmental property. But even after environmental rights are incorporated into a constitution, there may be theoretical and practical difficulties in their implementation.展开更多

Because consanguinity unmasks autosomal recessive disorders, we hypothesized that the frequency of CMMR-D is inflated in the highly consanguineous population of Saudi Arabia. In this study, 371 pediatric and young adult?patient samples from Saudi Arabia that cover the tumor spectrum of CMMR-D syndrome were analyzed for biallelic germline mutations in the MLH1, MSH2, MSH6 and PMS2 with the use of direct genomic sequencing. However, none of the 371 patients involved in the study was found to have biallelic pathological mutations of MLH1, MSH2, MSH6 or PMS2. This result indicates that CMMR-D is exceptionally rare among pediatric cancer patients and adult early onset cancer patients, even in the highly consanguineous Saudi population. Our findings suggest that larger cohorts will be needed, particularly in outbred populations, to determine the frequency of CMMR-D and that routine screening for this syndrome among cancer patients is not warranted.展开更多

The source of the human rights legislation obligations of the legislative organs of China is the Constitution of China, not the international human rights conventions. The legislature should understand and grasp the main contents of the human rights legislation obligations of the legislature according to Paragraph 3 of Article 33 of the Constitution while the interpretation of this clause must be based on the relevant provisions of the international human rights conventions. Human rights legislative obligations of the legislature can be classified into two types: legislative protecting obligations and legislative relief obligations of human rights. The NPC and its Standing Committee should be structurally responsible for the human rights legislation obligation, and the State Council and other organs of the State not for the legislation protection of human rights. A special human rights law should be enacted by the NPC.展开更多

However, the existing constitutive models present challenges tothe widespread implementation of ECD technology, and there is limited availability of finite element analysis (FEA)software capable of accurately modeling the behavior of ECDs. This study addresses these issues by developing anewconstitutivemodel that is both easily understandable and user-friendly for FEAsoftware. By utilizing numericalresults obtained from electromagnetic FEA, a novel power law constitutive model is proposed to capture thenonlinear behavior of ECDs. The effectiveness of the power law constitutive model is validated throughmechanicalproperty tests and numerical seismic analysis. Furthermore, a detailed description of the application process ofthe power law constitutive model in ANSYS FEA software is provided. To facilitate the preliminary design ofECDs, an analytical derivation of energy dissipation and parameter optimization for ECDs under harmonicmotionis performed. The results demonstrate that the power law constitutive model serves as a viable alternative forconducting dynamic analysis using FEA and optimizing parameters for ECDs.展开更多

文摘The formation of personality comes from people’s choices and pursuit of self-realization,which is influenced by objective factors but not determined by them,so personality does not belong to the domain of objectivity.The concept of general personality rights in the German Constitution was initially premised on the objective determinability in the field of personality,but in constitutional jurisprudence,it gradually shifted to something with individual autonomy as the core and personal self-realization as the goal,and the scope of relevant rights expanded accordingly,so that they could not be clearly distinguished from general freedom of action and thus became the general principle of constitutional rights.The protection of constitutional personality rights in the United States and Japan can also confirm this process,providing evidence for the constitutional nature of personality rights.Deeper research shows that constitutional personality rights actually manifest the highest value of modern constitutions—human dignity.In contrast,the theoretical justification of personality rights in civil law just lies in the objectivity and defensive nature of personality elements.

文摘The right to the protection of personal data is an important human right in the era of big data and a constitutional right based on the national protection obligation and the theory of human dignity,making it of special significance for the realization of citizenship in a digital society.It can be seen from an examination of the constitutional texts of various countries in the world that the right to the protection of personal data as a constitutional right has rich normative connotations,and the key legal link to realize this right lies in the national legislature actively fulfilling its obligation to shape and specify the protection of personal data in accordance with the entrustment of the constitutional norms.Given the constitutional principles of fundamental rights protection,i.e.,realizing the constitutional status of the right to the protection of personal data as a basic right by means of institutional guarantees,the legislature should first adhere to the constitutionality principle of data protection legislation.Second,a multi-level data protection legal system centered on the right to the protection of personal data should be established.Finally,the institutional guarantee mechanism for the protection of personal data should be continuously improved through constitutional interpretation.
文摘Eddy current dampers (ECDs) have emerged as highly desirable solutions for vibration control due to theirexceptional damping performance and durability. However, the existing constitutive models present challenges tothe widespread implementation of ECD technology, and there is limited availability of finite element analysis (FEA)software capable of accurately modeling the behavior of ECDs. This study addresses these issues by developing anewconstitutivemodel that is both easily understandable and user-friendly for FEAsoftware. By utilizing numericalresults obtained from electromagnetic FEA, a novel power law constitutive model is proposed to capture thenonlinear behavior of ECDs. The effectiveness of the power law constitutive model is validated throughmechanicalproperty tests and numerical seismic analysis. Furthermore, a detailed description of the application process ofthe power law constitutive model in ANSYS FEA software is provided. To facilitate the preliminary design ofECDs, an analytical derivation of energy dissipation and parameter optimization for ECDs under harmonicmotionis performed. The results demonstrate that the power law constitutive model serves as a viable alternative forconducting dynamic analysis using FEA and optimizing parameters for ECDs.

文摘The complex mechanical and damage mechanisms of rocks are intricately tied to their diverse mineral compositions and the formation of pores and cracks under external loads.Numerous rock tests reveal a complex interplay between the closure of porous defects and the propagation of induced cracks,presenting challenges in accurately representing their mechanical properties,especially under true triaxial stress conditions.This paper proposes a conceptualization of rock at the mesoscopic level as a two-phase composite,consisting of a bonded medium matrix and frictional medium inclusions.The bonded medium is characterized as a mesoscopic elastic material,encompassing various minerals surrounding porous defects.Its mechanical properties are determined using the mixed multi-inclusion method.Transformation of the bonded medium into the frictional medium occurs through crack extension,with its elastoplastic properties defined by the DruckerePrager yield criterion,accounting for hardening,softening,and extension.MorieTanaka and Eshelby’s equivalent inclusion methods are applied to the bonded and frictional media,respectively.The macroscopic mechanical properties of the rock are derived from these mesoscopic media.Consequently,a True Triaxial Macro-Mesoscopic(TTMM)constitutive model is developed.This model effectively captures the competitive effect and accurately describes the stress-deformation characteristics of granite.Utilizing the TTMM model,the strains resulting from porous defect closure and induced crack extension are differentiated,enabling quantitative determination of the associated damage evolution.
