Under which conditions is carrier cooperation possible? A case study in a Seville marketplace

The high volume of traffic originates two well-known problems in many cities: congestion and pollution. In recent years, a social phenomenon is emerging cooperation. This work is aimed at evaluating the circumstances under which transport cooperation is possible between different stakeholders operating in the same geographical area. To this end, a double survey process was conducted in a marketplace situated in the Seville City (Spain) centre. The first survey was designed to know the characteristics of the retailers and their preferences with respect to cooperation and regulations. A relational analysis between retailer features and their willingness to cooperate was carried out. After analysing the motivations for non-cooperation, a mixed proposal was designed and surveyed. Although the research was limited to a marketplace, the relevant data gathered from this double survey process highlights some implications: (a) the importance of personal relations in retailer cooperation; (b) a high volume of freight and the use of vans as on-street warehouses appear as significant motivations for non-cooperation; (c) forcing changes in the statu quo encourages cooperation.Ministerio de Economía y Competitividad (España) TEC2013-47286-C3-3-

Gender differences in cardiac left ventricular mass and function: clinical and experimental observations

Background: The aim of this study was to evaluate gender-associated impact on left ventricular mass (LVM) and on left ventricular function (LVF) in humans and rats with aging. Methods: Myocyte area and collagen volume fraction (CVF) were studied in rats. LVM and LVF were evaluated in animals and humans by echocardiography and LVM index (LVMI) was obtained. Results: LVMI, myocyte area and CVF were similar in males and females of 1-month-old rats. LVMI in children was similar in both genders. In contrast, in 6-month-old rats (5 males and 5 females), LVMI (17.7 ± 0.7 mg/mm vs. 10.1 ± 0.2 mg/mm; p < 0.01), and myocyte area (4572.5 ± 72.6 μm2 vs. 3293.85 ± 57.8 μm2 , p < 0.01) were higher in male animals without differences in CVF. Men (n = 25) exhibited greater LVMI than women (n = 25) (77.4 ± 3.2 g/m2 vs. 63.3 ± 1.8 g/m2 , p < 0.01), whereas the LVF was higher in women (105.9 ± 2.9% vs. 95.3 ± 3.5%, p < 0.01). Conclusions: There is a clear gender-associated impact on LVM with aging in humans and rats. Similar CVF and LVF associated to greater myocyte size and LVM in male rats suggest a process of physiological response. However, the increase in cardiac mass without an associated improved cardiac function in men in comparison to women could likely represent a potential disadvantage in the adaptive response during growth.

Skausmas kaip antrinė savybė: fenomenologinė prieiga

This work proposes that pain meets the requirements of being characterized as a secondary quality, as it&nbsp;covers, like a color, a determined extension. The argument seeks to establish a literal pain-color analogy through an inquiry into the intensity and location of the pain. From the classic intensity/location relationship reported by patients with acute appendicitis, three degrees of pain are distinguished: mild, moderate, and severe. The objective is only achieved by examining the Body’s extensional determinations (primary quality) insofar as each of these degrees of pain&nbsp;covers&nbsp;three particular measures. Once these three measures have been explored according to the perforation process (tissue damage), the work ends by identifying pain as a transcendent moment.Šiame darbe teigiama, kad skausmas gali būti apibūdintas kaip antrinė savybė, kadangi jis, kaip ir spalva, turi apibrėžtą ekstensiją. Straipsnyje siekiama nustatyti tiesioginę skausmo ir spalvos analogiją tyrinėjant skausmo intensyvumą ir vietą. Remiantis klasikiniu ūmaus apendicito priepuolį patyrusių pacientų nusakytu skausmo stiprumo ir vietos santykiu, išskiriami trys skausmo laipsniai: nežymus, vidutinis ir stiprus. Tikslas pasiekiamas tik ištyrus kūno apimties determinacijas (pirminė savybė) tiek, kiek šie skausmo laipsniai apima tris konkrečius matavimus. Įvertinus šiuos tris konkrečius matavimus pagal perforacijos procesą (audinio sužalojimą), straipsnyje skausmas pripažįstamas transcendentiniu momentu

A viral system to optimise the daily drayage problem

The intermodal transport chain can become more efficient by means of a good organisation of the drayage movements. Drayage in intermodal container terminals involves the pick up or delivery of containers at customer locations, and the main objective is normally the assignment of transportation tasks to the different vehicles, often with the presence of time windows. This paper focuses on a new approach to tackle the daily drayage problem by the use of viral system (VS). VS is a novel bio-inspired approach that makes use of a virus-infection biological analogy that is producing very satisfactory results when dealing with complex problems with huge feasibility region.Unión Europea TEC2013-47286-C3-3-

A satellite navigation system to improve the management of intermodal drayage

The intermodal transport chain can become more efficient by means of a good organization of the drayage movements. Drayage in intermodal container terminals involves the pick up or delivery of containers at customer locations, and the main objective is normally the assignment of transportation tasks to the different vehicles, often with the presence of time windows. The literature shows some works on centralised drayage management, but most of them consider the problem only from a static and deterministic perspective, whereas the work we present here incorporates the knowledge of the real-time position of the vehicles, which permanently enables the planner to reassign tasks in case the problem conditions change. This exact knowledge of position of the vehicles is possible thanks to a geographic positioning system by satellite (GPS, Galileo, Glonass), and the results show that this additional data can be used to dynamically improve the solution

Dynamic approach to solve the daily drayage problem with travel time uncertainty

The intermodal transport chain can become more e cient by means of a good organization of drayage movements. Drayage in intermodal container terminals involves the pick up and delivery of containers at customer locations, and the main objective is normally the assignment of transportation tasks to the di erent vehicles, often with the presence of time windows. This scheduling has traditionally been done once a day and, under these conditions, any unexpected event could cause timetable delays. We propose to use the real-time knowledge about vehicle position to solve this problem, which permanently allows the planner to reassign tasks in case the problem conditions change. This exact knowledge of the position of the vehicles is possible using a geographic positioning system by satellite (GPS, Galileo, Glonass), and the results show that this additional data can be used to dynamically improve the solution
