Pla estratègic del Grup d'Empreses ASS-4

L'objectiu d'aquest Treball Final de Grau es desenvolupar un Pla estratègic, en el què es defineixen les característiques del model de negoci Grup d'Empreses ASS-4, tant com els procediments i estratègies que es desenvoluparan per a l'expansió de l'empresa. D'aquesta forma es vol conèixer si la inversió a realitzar seria viable econòmica i financerament. La finalitat és l'aplicació dels coneixements adquirits durant els cursos del Grau en Administració i Direcció d'Empreses. Les assignatures han sigut estructurades per a que es tinguen els coneixements sobre les diferents àrees de l'empresa, al finalitzar el grau. Totes les assignatures han format part d'aquest projecte. L'empresa ASS-4, dirigida per Antonio E. San José Silvestre,des de l'any 1992. És una empresa dedicada a cobrir les necessitats del mercat de sistemes de neteja i higiene professional. La seua principal activitat és la distribució de borses de plàstic, ecològiques, de brossa,... També ofereixen solucions personalitzades que més convenen als seus clients. Als inicis l'empresa sols es dedicava a la compra venda de productes plàstics, i va anar expandint-se al mercat fins a cobrir tot el mercat. Els clients s'encontren en qualsevol sector de productes de consum: alimentació, forns, fruiteries, bars, supermercats, hotels, servicis, hospitals, comerços, altres empreses de compravenda de productes plàstics i químics.Gómez Llácer, E.

Evaluation of the efficacy of Steinernema carpocapsae against the Red Palm Weevil, Rhynchophorus ferrugineus in Phoenix canariensis

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is an important pest of palms. It has recently colonized the Mediterranean Basin, where it is a serious problem on ornamental Phoenix canariensis (Chabaud) palms. The efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in a chitosan formulation (Biorend R®) against this weevil in a semi-field trial including both preventative and curative assays has been studied. Our results prove the potential of this nematode to control R. ferrugineus. Efficacies around 80% were obtained in the curative assay, and up to 98% in the preventative treatment. Applications repeated every 2–3 weeks during the critical flight periods could prove effective to protect palms from this weevil in the Mediterranean Basi

Using the Uniform Theory of Diffraction to Analyze Radio Wave Propagation along Urban Street Canyons for Device-to-Device Communication

This paper examines the propagation of radio waves in so-called urban street canyons through formulations based on Geometrical Optics (GO) and the Uniform Theory of Diffraction (UTD). As this type of environment comprises a street flanked by tall buildings more or less equally spaced on both sides (creating a canyon-like morphology), estimating the attenuation that radio signals may experience in these scenarios is crucial to the planning of urban device-to-device (D2D) wireless communication. In this sense, the results obtained through the analysis based on GO/UTD (in the horizontal plane containing the transmitter and receiver) are validated by a comparison with experimental measurements, showing good agreement. This work demonstrates how the use of GO/UTD-based formulations can contribute to a simpler and computationally more efficient planning of D2D mobile communication systems in which the considered propagation environment can be modeled as an urban street canyon comprising rectangular and equispaced buildings.This work was supported by the Ministerio de Ciencia e Innovación, Spain, under Grant PID2019-107885GB-C33.

Effect of variable photoperiod on development and survival of Cirrospilus sp. nr. Lyncus (Hymenoptera: Eulophidae), an ectoparasitoid of phyllocnistis citrella (Lepidoptera: Gracillariidae)

No differences could be observed neither in development times nor on survival of C. sp. near lyncus exposed to three different photoperiods: 16:8; 12:12 and 8:16 (L.D). Therefore, conservation tactics aimed at favoring the winter permanence of this species in citrus orchards could increase the impact of this opportunistic parasitoid on its host P. citrella

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is an important pest of palms. It has recently colonized the Mediterranean Basin, where it is a serious problem on ornamental Phoenix canariensis (Chabaud) palms. The efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in a chitosan formulation (Biorend R(A (R))) against this weevil in a semi-field trial including both preventative and curative assays has been studied. Our results prove the potential of this nematode to control R. ferrugineus. Efficacies around 80% were obtained in the curative assay, and up to 98% in the preventative treatment.
