    Treatment technologies of fresh market wastewater

    Get PDF
    Fresh Market Wastewater (FMWW) is rich with high amounts of suspended solids, organic and inorganic compounds, nutrients, gases and some elements which come from fish entrails and seafood preparation sales, meat cutting, poultry slaughtering, fruits and vegetables sales. The excess of these parameters are harmful to the aquatic life since the FMWW is usually discharged into the drainage systems without any treatment or partial treatment. The FMWW technologies are developed due to some technical factors influencing the designation and construction. There are several projects of fresh market treatment technologies used on site area in small scale which could be replicated to other fresh market, and some case study have been tested in laboratory batch experiments. All the projects exhibited an efficiency to reduce critical parameters in FMWW and give positive impacts to the locals and responsible parties

    The diet of long-beaked common dolphin Delphinus capensis, dusky dolphin Lagenorhynchus obscurus, Burmeister’s porpoise Phocoena spinipinnis, and bottlenose dolphin Tursiops truncatus, was determined based on 281 stomach contents collected along the Peruvian central coast and San Juan de Marcona in the period 1987-1993. Counts of otoliths, squid beaks and some other remains were used to estimate frequency of occurrence and prey percentage of composition (PC). Long-beaked common dolphins (n=117) fed mainly on fish (98.71% of preys), the remainder was composed of squids and crustaceans: Peruvian anchovies Engraulis ringens (PC= 71.14%), Vincigerria lucetia (7.89%), Lampanictus parvicauda (6.77%), Merluccius gayi (4.49%), Odontesthes regia (3.54%), Mictophum nitidulum (2.62%) and Trachurus picturatus (1.42%). Dusky dolphins (n=66) consumed E. ringens (49.8%, 16.9%), L. parvicauda (23.6%, 0.1%), T. picturatus (17.1%, 0%), Normachthys crockery (0%, 76.4%), V. lucetia (3.5%, 0.1%), and Sardinops sagax (2.8%, 0 %) off the central Peruvian coast and San Juan de Marcona, respectively. In the same areas, Burmeister’s porpoise (n=67) fed on anchovies (90.37%, 81.89%), O. regia (6.64%, 0%), Anchoa sp. (1.13%, 0%), N. crockery (0%, 8.53%) and M. gayi (0.65%, 8.4%). Bottlenose dolphins (n=22) consumed L. parvicauda (39.24%), Sphiraena sp. (13.48%), S. sagax (13.31%), Prionotus sp. (9.59%), M. gayi (7.43%), T. picturatus (4.41%) and E. ringens (4.06%). The use of the Shannon & Wiener, Levins and Czekanowski’s indexes in combination with the feeding patterns of the sampled species indicated an opportunistic feeding strategy with respect to their preys. The four cetacean species studied are predators of both pelagic and mesopelagic large schooling fish species, and demonstrate no selectivity towards prey species but towards social behaviour and habitat. An average linkage cluster analysis showed high levels of similarity in the diets of the studied cetaceans. This low diversification and a high degree of overlap in trophic niches is probably related to the high productivity of the Peruvian upwelling ecosystem

    (±)-Gossypol induces apoptosis and autophagy in head and neck carcinoma cell lines and inhibits the growth of transplanted salivary gland cancer cells in BALB/c mice

    Racemic Gossypol [(±)-GOS], composed of both (-)-GOS and (+)-GOS, is a small BH3-mimetic polyphenol derived from cotton seeds. (±)-GOS has been employed and well tolerated by cancer patients. Head and neck carcinoma (HNC) represents one of the most fatal cancers worldwide, and a significant proportion of HNC expresses high levels of antiapoptotic Bcl-2 proteins. In this study, we demonstrate that (±)-GOS inhibits cell proliferation and induces apoptosis and autophagy of human pharynx, tongue, and salivary gland cancer cell lines and of mouse salivary gland cancer cells (SALTO). (±)-GOS was able to: (a) decrease the ErbB2 protein expression; (b) inhibit the phosphorylation of ERK1/2 and AKT; (c) stimulate p38 and JNK1/2 protein phosphorylation. (±)-GOS administration was safe in BALB/c mice and it reduced the growth of transplanted SALTO cells in vivo and prolonged mice median survival. Our results suggest the potential role of (±)-GOS as an antitumor agent in HNC patients

    The Bishop's Palace in Murcia is one of the few 18th century Spanish Baroque monuments which conserves in its principal facade mural paintings as ornamental decoration, together with, fine stone-sculptured motits. This characteristic as well as the size and architectural quality of the building make it one of !he most unique without doubt. The decorative paintings represent in each of !he adornings, a group of motifs that are similar and form a type of tapestry, framed by attractive mouldings and rocaille (Rococo ornament) that surround medallions and shields in the form of a horn-ofplenty with rocaille. The state of conservation that this facade presents is very poor since thepictorial elements as well as the stone ones are highiy deteriorated. The diagnosis of its state will be referred to in more detail, intending to highlight the necessity to contribute to a prompt and adequate restoration that such a noble facade deserves.The Bishop's Palace in Murcia is one of the few 18th century Spanish Baroque monuments which conserves in its principal facade mural paintings as ornamental decoration, together with, fine stone-sculptured motits.

    [ES] La recuperación de la pintura mural romana en el sureste español se realiza, por una parte en las propias excavaciones in situ en los yacimientos, donde se puede encontrar esa pintura mural de dos formas, aún situada en los paramentos de las villas romanas, o bien al pie de dichos muros desplomadas, fragmentadas e incluso enterradas, siendo entonces necesario la colaboración en el trabajo de recuperación del arqueólogo y del restaurador. También se pueden recuperar pinturas murales romanas en los fondos de los museos arqueológicos, pues muchos conservan multitud de cajas con innumerables fragmentos de piezas murales halladas en excavaciones precedentes y almacenadas allí en espera del posterior estudio, clasificación y restauración. Ejemplos de todo ello se exponen más adelante.[EN] Recovery of the Roman wall painting in the southeast Spanish is done, by a party's own excavations in the archaeological site, where you can find this mural in two ways, still located in the walls of Roman villas or at the foot of these walls collapsed, fragmented and even buried, making it necessary cooperation in the recovery work of the archaeologist and restorer. You can also recall Roman wall paintings in the collections of archaeological museums, as many boxes remain innumerable multitude of fragments of mural pieces found in excavations and record stored there pending further study, grading and restoration. Examples of the above are discussed.Santiago Godos, V. (2013). La recuperación y restauración de la pintura mural romana en el sureste español.

    How Does Reciprocity Affect Undergraduate Student Orientation towards Stakeholders?

    Get PDF
    5987Nowadays, students are more aware of the impact of companies on their stakeholders and the need for properly handling their expectations to operationalize corporate social responsibility. Nevertheless, little is known about how certain individual traits may relate to their stance on the issue. This exploratory research contributes to stakeholder theory by analysing the e ect of the individual’s decision-making process, including the consideration of their social preferences, on their orientation toward stakeholder management. Here, we draw upon a theoretical model for resource-allocation decision-making consisting of reciprocal and non-reciprocal components. Our data, from undergraduate students enrolled in di erent degrees, were collected through a questionnaire and two social within-subject experiments (ultimatum and dictator games). Thus, our results show that the presence of a reciprocal component when decisions are made is positively linked to an instrumental orientation toward stakeholders. In addition, a greater non-reciprocal component in the decision-making process corresponds to a more normative orientation.S

    [EN] Previous studies have established that there is a positive evolution of the quantity ofcorporate social responsibility (CSR) research output in terms of published papers. Sofar, however, there has been little discussion about how influential it has becomewithin the business discipline. This article seeks to obtain data which will help toaddress this research gap. The databases Web of Science andJournal Citation Reports(JCR) were used to carry out analyses at the journal and article levels. Results con-firmed a solid growth in CSR research and revealed that papers on the topic havegained attention from the scientific community. Furthermore, CSR articles are mostlyconcentrated in a small number of specialized journals, and opting for these journalsmay be related to the total citations. The conclusions drawn from this study may beespecially useful for academic managers and business researchers interested in theevaluation of academic performance.S

    El lenguaje es la pieza primordial dentro del desarrollo del niño que permite la socialización, en base a la comunicación con otras personas haciendo posible, además, dinamizar el bagaje cultural de forma permanente. Por ello es necesario tener una perspectiva del nivel de desarrollo de las habilidades comunicativas orales en la que se encuentra el niño a partir de las pruebas aplicadas en la Institución Educativa Inicial. El objetivo de esta investigación fue comprobar el nivel de desarrollo de su lenguaje oral en niños y niñas de 5 años de la Institución Educativa en Chiclayo. El estudio es de enfoque cuantitativo, nivel descriptivo – propositivo, tipo no experimental, cuyo objetivo es diseñar un programa de cuentos regionales que permita potenciar el lenguaje oral en niños de 5 años de una institución educativa inicial en Chiclayo. Participaron en el estudio diagnóstico 34 niños a quienes se les aplicó la prueba para medir el nivel del lenguaje oral (PLON- R), encontrándose que el 59% de los niños presentan niveles deficientes en su desarrollo. Está situación está relacionada con un conjunto de factores provenientes del medio y en consecuencia se puede afirmar que el diseño de cuentos regionales contribuirá a potenciar el lenguaje oral. Cabe destacar, entre otras bondades de la propuesta, los fundamentos desde el enfoque sociocultural; plasmándose la gestión didáctica con mayor cantidad de situaciones interactivas, orientadas a responder la problemática
