Realization of a Low Emission University Campus Trough the Implementation of a Climate Action Plan
AbstractThe Climate Action Plan (CAP) experience started a few years ago with the aim to manage carbon and energy more efficiently. CAP is a roadmap to get Universities to the goals of climate protection, defining a carbon footprint, identifying priority actions, milestones to measure progresss and target dates, raising funding opportunities. The methodological approach for the realization of a Low Emission Campus through the implementation of a CAP at the South East European University (SEEU) in Tetovo (Macedonia) foresees the analysis of the current energy consumptions and Greenhouse Gas (GHG) emissions and the integrated planning for the implementation of carbon friendly measures. CAP provides the cost-benefit analysis of the most suitable projects and associated yearly and cumulative GHG reductions, and defines the schedule for their gradual implementation. The Climate Action Planning process represents a valuable learning opportunity for the whole SEEU campus community, especially for students, providing additional opportunities for educational and research activities
Pulmonary Lymphangiomyomatosis in Bourneville’s Tuberous Sclerosis: Case Report
Lymphangiomyomatosisis a rare disease characterized by a proliferation of abnormal smooth muscle cells responsible for infiltration with the destruction of tissue architecture and genesis of cystic lung and lymphatic lesions. In addition to lung damage, Bourneville’s tuberous sclerosis (BTS) also affects the skin, brain, retina, kidneys, and, less frequently, the heart and bone.
We report the case of a young patient with bilateral pneumothorax revealing pulmonary lymphangiomyomatosis in the context of Bourneville’stuberoussclerosis BTS
Chemical variability and acaricidal activity of Rosmarinus officinalis L. essential oils
Rosemary leaves are characterized by two main periods of essential oils production and contain high levels of oils (2.11 to 3.13%). Their oils, extracted by hydrodistillation and analyzed by GC-FID and GC-MS, are dominated by oxygenated and hydrocarbons monoterpens and contain high amounts of 1,8-cineole. The chemical composition didn’t vary drastically during the phenologic stages, but a noticeable variability is however found within the ten studied populations. PCA and regression analysis revealed that among factors regulating the biosynthesis of oils during the different growth stages of the plant, the mean monthly temperature and monthly precipitation would be determinant. In hives bioassays, the use of absorbent paper pad impregnated by pure rosemary oil for six days showed certain effectiveness against Varroa mites. So, an application rate of 5ml of rosemary oil caused the highest mites mortalities, but the concentration of 3ml that producing an equivalent toxicity to flumetrin, is recommended. To overcome the phenomenon of resistance to chemicals widely used in apiaries infested by Varroa destructor, the use of pure rosemary oils as biopesticide for controlling acarian pests would be an appreciated tool

La inoculación con bacterias del ácido acético mejora la calidad de las aceitunas de mesa verdes naturales
This study aims to develop a method for the preparation of natural table olives using locally selected microorganisms and without resorting to the usual techniques which employ lye treatment and acids. The effects of parameters, such as lye treatment, inoculation with yeasts, substitution of organic acids with vinegar and/or acetic acid bacteria, and finally alternating aeration have been assessed. Four different combinations were applied to the “Picholine marocaine” olive variety using indigenous strains, namely Lactobacillus plantarum S1, Saccharomyces cerevisiae LD01 and Acetobacter pasteurianus KU710511 (CV01) isolated respectively from olive brine, Bouslikhen dates and Cactus. Two control tests, referring to traditional and industrial processes, were used as references. Microbial and physicochemical tests showed that the L3V combination (inoculated with A. pasteurianus KU710511 and L. plantarum S1 under the optimal growth conditions of the Acetic Acid Bacteria (AAB) strain with 6% NaCl) was found to be favorable for the growth of the Lactic Acid Bacteria (LAB) strain which plays the key role in olive fermentation. This result was confirmed by sensory evaluation, placing L3V at the top of the evaluated samples, surpassing the industrial one where a chemical debittering treatment with lye was used. In addition, alternating aeration served to increase the microbial biomass of both AAB and LAB strains along with Saccharomyces cerevisiae LD01 strain, but also to use lower concentration of NaCl and to reduce the deterioration of olives compared to the anaerobic fermentation process. Finally, a mixed starter containing the three strains was prepared in a 10-L Lab-fermenter from the L3V sample in order to improve it in subsequent studies. The prepared starter mixture could be suitable for use as a parental strain to prepare table olives for artisan and industrial application in Morocco.Este estudio tiene como objetivo desarrollar un método para la preparación de aceitunas de mesa naturales utilizando microorganismos seleccionados localmente y sin recurrir a las técnicas habituales que utilizan el tratamiento con lejía y ácidos. Se han evaluado los efectos de parámetros como el tratamiento con lejía, la inoculación con levaduras, la sustitución de ácidos orgánicos por bacterias de vinagre y/o ácido acético, y finalmente la aireación alterna. Se ensayaron cuatro combinaciones diferentes en la variedad de aceituna «Picholine marocaine» utilizando cepas autóctonas, como Lactobacillus plantarum S1, Saccharomyces cerevisiae LD01 y Acetobacter pasteurianus KU710511 (CV01) aisladas respectivamente de salmuera de aceitunas, Bouslikhen y Cactus. Se utilizaron como referencia dos pruebas de control, referidas a procesos tradicionales e industriales. Las pruebas microbianas y fisicoquímicas mostraron que la combinación L3V (inoculada con A. pasteurianus KU710511 y L. plantarum S1 en las condiciones óptimas de crecimiento de la bacteria del ácido acético (AAB) con NaCl al 6%) resultó ser favorable para el crecimiento del Láctico. Las cepas de bacterias ácidas (LAB) juegan un papel clave en la fermentación de las aceitunas. Este resultado fue confirmado por la evaluación sensorial colocando L3V en la parte superior de las muestras evaluadas, superando a la industrial, donde se usó un tratamiento de eliminación química con lejía. Además, la aireación alterna permitió aumentar la biomasa microbiana de las cepas AAB y LAB junto con la cepa Saccharomyces cerevisiae LD01, también usar una concentración más baja de NaCl y reducir el deterioro de las aceitunas, en comparación con la operación de fermentación anaerobia. Finalmente, se preparó un iniciador mixto que contenía las tres cepas en un fermentador de laboratorio de 10-L a partir de la muestra L3V con el objeto de mejorarlo en los estudios posteriores. El iniciador de mezcla preparado podría ser adecuado para usarse como una cepa parental para preparar aceitunas de mesa para aplicaciones artesanales e industriales en Marruecos
GENETIC IMPROVEMENT OF KANINJOT VARIETY FROM CLONAL SELECTION
Abstract: The "Kaninjot" cultivar, autochthonous and widespread is remarkable for high percentage and good quality of the oil. It has dual use. It has periodical production, but the variability that this genotype possesses has been exploited through clonal selection to find individuals with high production constant, oil percentage and bigger average fruit weight. The selection underwent two phases: In the first phase: over a population of 2583 trees, in a five year period, where each year the trees that were qualified had inflorescence and fructified, while the others were considered out of use. In the second phase for 17 clone candidates derived from selection of the first phase production evaluation was done for kg/trees/ year, (i) oil percentage % fresh matter done through Soxhlet, (iii) average fruit weight (g), (iv) production periodicity estimated through Pearce and Dobersek-Urbank. Each clone displayed differently its genetic potentials, with differences for production constant. Constant production had 6 individuals (0.00 -0.30). The variability for fruit weight was from 0.26 g up to 1.24 g more than the standard (12 individual). For the oil percentage 6 individuals with 0.1 up to 2.1% more than the average of the population were selected. In the final evaluation there resulted to be: (i) 12 clones with superior PC. (ii) 6 clones possess superior for constant production and oil percentage (PC+OP). (iii) 6 clones possess the three selection features; constant production, oil percentage and fruit weight (PC+Fw+Op). The selected individuals have differences as far as the pomological and technological characteristics are concerned
The susceptibility of Escherichia coli strains to essential oils of Rormarinus officinalis and Eucalyptus globulus
Essential oils are frequently used for flavour and fragrance in the perfume, pharmaceutical, cosmetic and food industries. They are also suitable raw material for production of new synthetic agents. The antibacterial activity of the essential oils obtained by steam distillation of Rosmarinus officinalis L and Eucalyptus globules collected in south Morocco was studied by micro-atmospheric technique against Escherichia coli CIP54127 and E. coli isolated from urine and resistant to several antibiotics. Both essential oils were effective against the two strains bacteria in particularly against E. coli CIP54127. MIQ of both oils ranged from 60 to 70 ìl for both bacteria. In conclusion, results show that essential oils are effective and could be considered as a natural antimicrobial source that can be used on production of natural antimicrobial agents
Temporomandibular Joint Ankylosis as a Complication of Neonatal Septic Arthritis : Report of two cases
Temporomandibular joint (TMJ) ankylosis as a complication of neonatal septic arthritis is rarely reported in the literature. We report two clinical cases of unilateral TMJ ankylosis occurring in paediatric patients subsequent to neonatal septic arthritis. The first case was a 15-month-old male infant who presented to the Sultan Qaboos University Hospital, Muscat, Oman, in May 2010. According to the published English scientific literature, he is the youngest person yet to be diagnosed with this condition. The second case was a five-year-old female who presented to the Al-Nahda Hospital, Muscat, Oman, in October 2011. Both cases presented with facial asymmetry and trismus. They subsequently underwent gap arthroplasty and interpositional temporalis muscle and fascia grafts which resulted in an immediate improvement in mouth opening. Postoperatively, the patients underwent active jaw physiotherapy which was initially successful. Both patients were followed up for a minimum of two years following their surgeries
Disinfection of Drinking Water and Trihalomethanes: A Review
Trihalomethanes (THMs) as the main disinfection by-products (DBPs) during the last four decades have concerned the public and scientific opinion for the possible carcinogenic effect on human health. The purpose of this paper is to investigate the disinfection of drinking water, types of DBPs and the formation of THMs. The formation of THMs during the chlorination process represents a serious health problem, as they significantly increase the possibility of the risk of several types of cancers. In this article we are discuss the health risk imposed by THMs, considered toxic and possible carcinogenic as well as mutagenic to the human
body. Thus, their elimination and regular monitoring is imperative. In this article we present the removal technologies for the THMs and their precursors. This article also provides the basic information related to the analytical methods for the determination of the THMs
