Technical requirements for vehicles prepared for the carriage of dangerous goods by road

España es un país con un elevado índice de transportes de mercancías peligrosas por carretera. Esta actividad, que de modo indubitado resulta tan peligrosa pues genera unos riesgos inherentes para la población y la protección del medio ambiente, se lleva a cabo por medio de un vehículo con unas características especiales. Así, en el trabajo que aquí se presenta, se realiza un exhaustivo estudio de la abundante normativa que afecta a esta actividad tan transversal. A estos efectos, se hará un recorrido por las prescripciones técnicas de estos vehículos; la señalización; la clasificación, etiquetado y envasado de sustancias peligrosas, con objeto de hacer hincapié en su normativa para, de este modo, las partes cumplan todas las disposiciones y así, se evite o minimice la aparición de los graves riesgos laborales que la actividad genera.Spain is a country with a high rate of transport of dangerous goods by road.

The obligation of digital reconnection by the worker and its close imbrication in mental health

Echo of the French legislation that was a pioneer worldwide in the regulation of the right to digital disconnection at work, the right arose in Spain at the end of 2018 in order to guarantee that the worker does not suffer interference in his right to rest through digital devices. Although the right to rest already exists in Spain since before this specific regulation, its emergence has been due to the unstoppable advance of Information and Communication Technologies (ICT) at work. Thus, the effects from safety and health at work are evident due to excessive use of e-mail, mobile phones or instant messages via WhatsApp. Even more so when, as will be analyzed in this paper, labor law is not absolute, so it may be invalidated in urgent and urgently needed situations, justified by the company. Under these circumstances, employees, in their break time, have to digitally reconnect with the company, which entails an extension of the working day and, therefore, greater probabilities of damages derived from these work benefits may arise. In digital terms, emphasis must be placed on occupational risks of a psychosocial and ergonomic nature

The Need to Train and Educate Employees and Managers to Drive Self-Transformation and Disconnection From Digital Technology

All workers, but especially managers in charge and managers, must be trained and made aware of the risks of computer fatigue and the need to exercise the right to digital disconnection. In this way, an important step will be taken to change the business culture and climate and thus promote the well-being of workers. If managers and managers hardly disconnect from technology, hardly will their collaborators. In short, both one and the other must be aware of the physical psychosocial risks of not disconnecting after a day's work or during permits, vacations or temporary disabilities. Without a doubt, the computer fatigue that the Spanish legislator incorporated at the end of 2018 is the most serious psychosocial risk that the position with command and the worker can suffer. To avoid it, training and awareness actions are essential to clarify the dangers of constant non-connectivity to digital and telematic media

The “Digital Disconnect” on the Back of Occupational Health and Safety

The importance of digital disconnection in the workplace cannot be overstated, as it plays a crucial role in preserving the physical and mental well-being of employees. In today's hyper-connected world, the constant use of digital devices and online communication has blurred the boundaries between work and personal life. This continuous connectivity can lead to a range of health issues. Physically, excessive screen time and sedentary work can result in eye strain, headaches, and musculoskeletal problems. Additionally, a lack of time for relaxation and exercise can contribute to a host of chronic health conditions. Mentally, the relentless notifications and information overload can lead to burnout, stress, and anxiety. Continuous work-related communication, even after office hours, disrupts personal lives and makes it challenging for individuals to recharge and spend quality time with loved ones. Promoting digital disconnection by setting boundaries, encouraging regular breaks, and respecting off-hours can help employees maintain a healthier work-life balance. Ultimately, these practices enhance physical and mental health, leading to happier and more productive workers. Employers and employees must recognize the significance of this disconnect to create a sustainable and healthy work environment

Indirect monitoring method of tool wear using the analysis of cutting force during dry machining of Ti alloys

In recent decades, optimize tool life is in constant evolution so many researchers have focused to analysis the tool wear by indirect monitoring (e.g. acoustic emission, cutting forces, vibrations) that plays a significant role in control and improvement of product during of machining operations - in real time to prevent instabilities of process. On another hand, it is recalled that titanium alloys are used in many industries as aerospace sector that have been utilized in strength to weight ration reduction in some parts of aircraft. On the negative side, Ti alloys tends to be hard machining due to their mechanical properties such as low thermal conductivity and modulus of elasticity causing increase cutting temperature, tool breakage or possibility interruption of process.Universidad de Málaga.

Twisting, type-N vacuum gravitational fields with symmetries

The Einstein field equations for twisting, type-N fields in empty space possessing two noncommuting Killing vectors are reduced to a single second-order ordinary differential equation for a complex function. Alternative forms of this basic equation are also presented; in particular, an appropriate Legendre transform provides a partial linearization, leading to a single real, nonlinear, third-order ordinary differential equation

New backlund-transformations and superposition principle for gravitational-fields with symmetries

Vector Bäcklund transformations which relate solutions of the vacuum Einstein equations having two commuting Killing fields are introduced. Such transformations generalize those found by Pohlmeyer in connection with the nonlinear δ model. A simple algebraic superposition principle, which permits the combination of Bäcklund transforms in order to get new solutions, is given. The superposition preserves the asymptotic flatness condition, and the whole scheme is manisfestly O(2, 1) invariant

Stationary axisymmetric SU(2) Einstein-Yang-Mills fields with restricted circularity conditions are Abelian

In this paper we prove that in a stationary axisymmetric SU(2) Einstein-Yang-Mills theory the most reasonable circularity conditions that can be considered for the Yang-Mills fields imply in fact that the field is of embedded Abelian type, or else that the metric is not asymptotically flat

Assessing the potential for vertical urban agriculture for multi-storey buildings

This thesis proposes the use of urban agriculture as a tool to address three global challenges related to population growth in cities; densification, climate change and health risk by studying the history and benefits of urban agriculture, it is possible to understand the benefits in better integrating urban agriculture into new urban infrastructure, particularly in high-density housing areas. These benefits include; better living conditions, reduced food transportation, stormwater management and strong links between communities. The concept of urban agriculture in green infrastructure was tested with a case study of the proposed Törnrosen development in Rosengård, Malmö, to give a specific context to the theory, in which were used global examples of innovative urban agriculture projects for inspiration, alongside details of the current possibilities of urban green infrastructure technology and analysis of the study area and creative design solutions are developed to find out what is possible. The project finds that when green infrastructure is integrated into the Törnrosen tower, additional benefits to the residents and broader a community is likely to increase, if it is adapted to support urban agriculture, and alongside other urban agriculture community projects in the neighbourhood to have a more significant impact on the quality of life in Rosengård. The use of specific urban agriculture infrastructure will depend on location, type of users, the intention of the garden and stakeholders involved in the gardens. The design principals made to design and evaluate the community gardens could be used for other projects with similarities in the future
