Since then, two parallel traditions are present in Guatemala. In this paper, the authors present some cornments on the glazed pottery tradition. The ceramics analysed come from several monuments of Antigua Guatemala, mainly from the Convents of San Francisco and Santo Domingo, and the Palacio Arzobispal. The glazed pottery includes an important group of monochrome wares in green, brorwn, and, less popular, in yellow and grav, which are used for more utilitarian Purposes than a second class of glazed pottery, the white majolica. the main ceramic trend in colonial times. Majolica develops four designs combining green, yellow and black in its Polichrome version: it also appears heavily represented by green Phytomorphic designs on the white surface. The third rnajolicatype is the monochrome version in white, sometimes bearing a monogram of the religious order. Another important trend in the glazed wares of Antigua that depends directly on the majolica tradition is the use of blue color. This is a variety which seldom occurs in Antigua due to the lack of cobalt in Guatemala. There is a local development of the blue color tradition applied to the typical Antigua designs, but it never appears as frequently as the above mentioned majolicas. In recent times, the use ot blue color has gained an important position in the Guatemalan ceramics as a result of access to cobalt through importation.

We will analyze certain categories that allow us to a better understanding and definitions, which are some factors that influence children development. The violation of rights, affected thousands of children which are considered as subjects of rights, established and recognized within the framework of the Constitution, Code of Childhood and Adolescence, and other laws related to them; rights that have been qualified in function to the basic needs of human beings, by placing it as protagonist of the development and not as an object of it. When we talk about violation of the rights we are talking about the rights of citizens and the specific to their age, which have been threatened and abused, in its various forms of violence, such as: psychological, sexual and neglect, this violation has been done by their parents, family, teachers, and the people close to children`s environment, in addition to this, there is violence relate to a particular social class, gender, causing inequality; which we will analyze in the cases reported to the Board of Cantonal Rights Protection of Azogues, the main source for obtaining information in this analysis. The types of violence expressed will be analyzed according to the number of cases as filed in the institution previously mentioned because it is an institution guarantor of children`s rights in this canton, which ensure the compliance of the threatened rights violated, joining responsibility with the State, society and family.

Since the mass of material per stage will be very small, a collection surface which is to be weighed before and after sampling should itself have as little mass as possible. The glass or stainless steel surfaces included in impactors are heavy enough to cause large errors when determining the difference between two large numbers, but use of polyethylene greatly eases this situation. In addition, polyethylene has no hygroscopicity problems. Acknowledgment We are indebted to S. S. Brar of Argonne National Laboratory for providing us with the reference polystyrene filter material.

In order to evaluate the biodegradability of several plastics commercially developed for enhanced biodegradability, plastic films of two types-(i) polyhydroxybutyrate copolymerized with hydroxyvalerate (PHBV) and (ii) low density polyethylene (LDPE) incorporated with a starch filler-were incubated for 44 d under moist, aerobic conditions in two soils, an acid sand and a calcareous sandy loam. Biodegradability of the plastics was evaluated based on evolution of CO 2-C upon incubation and by microscopic examination after 44and 150-d incubation under the same conditions. Biodegradation of polyhydroxybutyrate films ranged from 5% to near complete biodegradation during the 44-d incubation, depending on soil type, film thickness, and the nature of chemical additives to the polymer. Granules of embedded starch exposed at the surface of starch-incorporated polyethylene films were degraded within 14 d, after which no further biodegradation could be detected; no gross deformations of the plastic film were associated with the loss of surface starch.
