Un enfoque gráfico y práctico García Pérez, Rosa María En esta obra se identifica el Derecho de obligaciones y contratos como parte del Derecho privado patrimonial; las relaciones jurídicas obligatorias, sus fuentes, sus elementos estructurales, su tipología y los efectos de su incumplimiento; el contrato como el principal mecanismo del que surgen obligaciones, sus elementos esenciales, su eficacia e ineficacia; y, por último, la responsabilidad por daños derivados del contacto social entre las personas. Los contenidos se desarrollan a partir de esquemas gráficos sobre las principales cuestiones y los problemas de fondo que plantean las diferentes instituciones jurídicas, con el propósito de explicarlas de forma sintética y visual.

Este trabajo presta especial atención, tras recientes iniciativas legislativas europeas en materia digital, a la problemática relativa a las bases legales que legitiman el tratamiento de datos personales con esta finalidad, especialmente cuando se trata de datos sensibles, en muchos casos «invisibles» por escapar al conocimiento y control del consumidor.; This paper examines the use of consumers’ personal data for the purposes of personalised commercial advertising. In light of recent European legislative initiatives in the digital sphere, this paper pays particular attention to the issues surrounding the legal bases that justify the processing of personal data for this purpose, especially where sensitive data is concerned, which is often ‘invisible’ as it escapes the consumer’s knowledge and control. https://hdl.handle.net/10481/112535 Parameters of masturbation: effects of gender and sexual orientation Landaluce, Millán; Sierra Freire, Juan Carlos; Cervilla Sáez, Óscar; Sánchez Pérez, Gracia María It has been proposed that the study of masturbation requires the analysis of several parameters (i.e. age at first masturbation, negative attitudes towards masturbation, solitary sexual desire, current frequency of masturbation and subjective orgasm experience). This study examines the effects of gender and sexual orientation on these parameters. A total of 1568 cisgender adults (493 heterosexual men, 478 gay men, 490 heterosexual women and 107 lesbian women) participated. The results indicate that, with respect to gender, men, compared to women, begin masturbating earlier, report more negative attitudes towards masturbation, experience greater solitary sexual desire, and masturbate more frequently, whereas women report a more intense subjective orgasm experience. In relation to sexual orientation, gay people, compared to heterosexual people, initiate masturbation earlier. The results also show that patterns differ between men and women depending on their sexual orientation. Specifically, whereas gay men scored higher than heterosexual people on solitary sexual desire, frequency of masturbation and subjective orgasm experience, lesbian women reported lower scores than heterosexual women on these variables. The roles of gender and sexual orientation in understanding masturbation are also discussed.

Broiler chicks of the same batch typically hatch over 24-48 h, not simultaneously. After hatching, exposure to suboptimal ambient temperatures, together with practices such as sexing, vaccination, and transport, delay their first feed and water intake, negatively impacting nutrient absorption and immune system development. Early nutrition strategies using lower Ca levels and highly digestible ingredients, like spray-dried porcine plasma, may mitigate these effects. This study compared a conventional hatchery system (CH) vs. on-farm hatching system (OFH) and three early feeding programs on performance (pen-based), tibia mineralization, and intestinal gene expression measured in representative male birds in Ross 308 broilers. Eggs from one breeder flock were divided as follows: 2 880 eggs at 18-day incubation were transported to the farm for OFH (initially 60 eggs/pen; 48 pens). At 21-day incubation (day 0), OFH pens were standardized to 39 chicks/pen (1 872 chicks total) to match conventional hatchery stocking density; surplus chicks were not enrolled. In parallel, 1 872 CH chicks from the same flock were transported ∼6 h (492 km) and placed in 48 pens. The study followed a three-way factorial design, including three starter feeding programs—S1: standard starter (0-10 days); S2: enhanced pre-starter (0-4 days) followed by standard starter (4-10 days); and S3: enhanced pre-starter (0-4 days) followed by enhanced starter (4-10 days)—by two hatching systems (CH vs. OFH), and by two sexes (female vs. male). All birds received common grower (10-28 days) and finisher (28-42 days) diets. During the starter phase, OFH chicks showed higher BW and greater tibia weight, ash weight, length, and breaking strength (P < 0.05), but performed similarly to CH chicks by the end of the cycle (P > 0.05) with few differences in bone properties. Feeding program S3 improved overall performance (P < 0.05) compared to S1 in both systems. Chicks fed the enhanced pre-starter diet exhibited upregulation of OCLN (P < 0.05), a gene associated with gut barrier integrity, compared with those on the standard diet. Chicks from CH showed higher expression (P < 0.05) of genes associated with immune response, barrier function, and stress adaptation, whereas OFH chicks showed gene expression patterns consistent with earlier intestinal maturation associated with immediate post-hatch feed access. Overall, optimized early feeding strategies based on low-Ca levels and highly digestible ingredients improved broiler growth performance and supported intestinal and bone development, whereas the effects of hatching system were mainly confined to the early post-hatch period. https://hdl.handle.net/10481/112531 Geografía Astronómica: Repertorio clásico y alfabético.
