Histo-anatomy of the stem of Solanum tuberosum L.

Analele Universitatii din Oradea, Fascicula Biologie , 2008,
Abstract: The paper reveals the anatomical structure of the stem of Solanum tuberosum L. in the incipient stages of the ontogenetic development (the popular denomination sprout”). Cross sections of the stem of this species were performed. The appearance of the secondary structure – even in this early ontogenetic stage – was confirmed by the presence of the cambium and the tissues generated by this. As a result, at the potato, the purely primary structure of the stem is of a short duration.
Histo-anatomical and histogenetic aspects in the stem and root of Chelidonium majus L.

Analele Universitatii din Oradea, Fascicula Biologie , 2008,
Abstract: The present study focuses on aspects of anatomy and histogenesis in the root and stem of common celandine (Chelidonium majus L.). The stem is annual, having a primary structure. It is to be noticed the depositing parenchyma within the medullar rays and around the vascular bundles. The secretory tissue from the near vicinity of the primary phloem gets together with this in the composition of the collateral vascular bundles. The chlorenchyma initially present in the structure of the common celandine stem shall be subsequently replaced by depositing and mechanic tissues. The primary perennial root has a diarch secondary structure. This structure is due to the functioning of the cambium and the phellogen along several years. The secondary phloem is a deposit for the amyloplasts, there being present here several laticifers. The ritidoma is well represented, black in colour, also rich in laticifers. The secondary roots have a medullar origin and disticha distribution.

Hydrometallurgical Processing and Recovery of Nickel from Spent Cathode Ray Tubes

Abstract: Scientific and technological progress required for more and more advanced electrical and electronic equipment (EEE). Therefore, EEE manufacturing became one of the most important world activities, generating at the same time huge amounts of waste. In the last decades the accumulation of waste electrical and electronic equipment (WEEE) has become a global problem (Widmer et al., 2005; Babu et al., 2007; Robinson, 2009). These wastes are a threat for the environment due to their high content of toxic materials and, at the same time, they are an important source of recyclable materials, and especially valuable metals (e.g. Au, Ag, Pd, Cu, Ni, Zn). Nowadays there are various approaches for the treatment and recycling of WEEE, involving pyro-, hydro- and bio-metallurgical processes (Cui and Zhang, 2008). Among WEEE, cathode ray tubes (CRT) displays, used mainly in computer monitors and television sets, are regarded as the most polluting fraction of all WEEE (Nnorom et al., 2011). CRT recycling represents a challenge due to their high accumulation rate, proportional to the evolution of modern technologies (flat panel displays), their high content of toxic and noxious substances (heavy metals and organic compounds), improper storage, and the lack of a complete, pollution-free recycling solution. Previous studies have shown that some CRT metallic components (electron gun - EG, shadow mask) contain important amounts of Ni (25 – 45%) and Fe (50 – 70%), and small quantities of Mn, Co and Cr (Robotin et al., 2011). Ni and Ni alloys play an important role in modern technology, especially due to their magnetic and anticorrosion properties. Unfortunately, when exposed inappropriately, Ni can have negative environmental effects and can be harmful to human health (Denkhaus and Salnikow, 2002). In this context, Ni recycling from electronic waste is important for environmental and health reasons, and, at the same time, Ni recycling could be financially sustainable due to an elevated Ni market price. In the current study we propose a technological process for Ni recovery from the metallic components of CRT waste. After a preliminary separation into glass, plastic, ceramic and metallic parts, the metallic components were subjected to a magnetic separation and their composition was determined. We have chosen to recover Ni from the magnetic components due to a higher content of Ni and to avoid the contamination with Cr (present in the non-magnetic components). In the next step, chemical and electrochemical waste solubilisation was performed (Robotin et al., 2011). Apart from
