A Novel Insect Overwintering Strategy: The Case of Mealybugs.

Insects have limited ability to regulate their body temperature and have thus required a range of strategies to withstand thermally stressful environments. Under unfavorable winter conditions, insects often take refuge under the soil surface to survive. Here, the mealybug insect family was selected for the study.

Photo-Fenton Degradation of Pentachlorophenol: Competition between Additives and Photolysis.

In the present work, the photo-Fenton degradation of pentachlorophenol (PCP, 1 mg/L) has been studied under simulated and natural solar irradiation; moreover, the effect on the process efficiency of urban waste-derived soluble bio-based substances (SBO), structurally comparable to humic acids, has been investigated. Experiments showed a crucial role of PCP photolysis, present in the solar pilot plant and hindered by the Pyrex filter present in the solar simulator. Indeed, the SBO screen negatively affects PCP degradation when working under natural solar light, where the photolysis of PCP is relevant.

A new methodology to assess the performance of AOPs in complex samples: Application to the degradation of phenolic compounds by O and O/UV-A-Vis.

A methodology combining experimental design methodology, liquid chromatography, excitation emission matrixes (EEM) and bioassays has been applied to study the performance of O and O/UVA-vis in the treatment of a mixture of eight phenolic pollutants. An experimental design methodology based on Doehlert matrixes was employed to determine the effect of pH (between 3 and 12), ozone dosage (02-1.0 g/h) and initial concentration of the pollutants (1-6 mg/L each).

Treatment and reuse of textile wastewaters by mild solar photo-Fenton in the presence of humic-like substances.

In this paper, the possibility of reusing textile effluents for new dyeing baths has been investigated. For this purpose, different trichromies using Direct Red 80, Direct Blue 106, and Direct Yellow 98 on cotton have been used. Effluents have been treated by means of a photo-Fenton process at pH 5.

Density and structure of Saissetia oleae (Hemiptera: Coccidae) populations on citrus and olives: relative importance of the two annual generations.

Saissetia oleae (Olivier) (Hemiptera: Coccidae) populations were studied and compared in citrus (Citrus spp.) and olive (Olea europaea L.) groves to determine the number of generations, crawler emergence periods and changes in population density during the year.

[An evaluation of the SMAST questionnaire for the diagnosis of alcoholism in primary care. The Self-Administered Short Michigan Alcoholism Screening Test].

Objective: To validate a self-administrable version of the SMAST questionnaire for diagnosing alcoholism at the primary care level.

Design: A descriptive study of a crossover type.

Setting: An urban health centre.

[Chronic necrotizing pulmonary aspergillosis caused by Aspergillus niger].

Chronic necrotizing pulmonary aspergillosis (CNPA), also known as semi-invasive pulmonary aspergillosis , is a recently defined entity. CNPA is characterized by a pulmonary infiltration with cavitation of chronic evolution in patients with chronic pulmonary disease, slight immunodeficiency or healthy patients. Good evolution is obtained with antimicotic treatment.
