Ecologia Balkanica , 2012,
Abstract: In the present study, the toxic effect of three different natural essential oils of medicinal plants, namely Garlic (Allium sativum), Mint (Mintha pipereta) and Eucalyptus (Eucalyptus globulus) were tested on 1st nymphal instar of the grasshopper (Heteracris littoralis). The LC50 values of the tested oils were estimated after 14 days from feeding on treated diet mixed with different concentrations of the oil. The LC50 of the tested oils were arranged as follows: 0.067, 0.075 and 0.084ml. /100ml. diet for Garlic, Eucalyptus and Mint respectively. The effect of LC50 concentration of the oils on the biological aspects and histological changes that observed on the alimentary canal and fat bodies were recorded. The normal development of the grasshopper was exhibited. Results cleared that there was statistical variable numbers of increased the nymphal periods, life cycle, adults longevity and life span comparing with the control test. Garlic oil inhibited egg lying by the resulting females offspring of the treated1st instar nymphs. High reduction in the deposited eggs and egg fertility caused by Eucalyptus or Mint oil and marked malformation were observed. Histological changes on the alimentary canal and fat bodies of the remaining nymphs after treatment with Garlic oil (the most effective oil) were detected by the light microscope have been recorded. The results suggest that the natural plant essential oils of Garlic, Eucalyptus and Mint may be used in IPM control program against H. littoralis grasshopper.
Significance of Prenuptial Rituals as Ethnic Definitional Ceremonies among Immigrants  [PDF]
Rachel Sharaby
Advances in Anthropology (AA) , 2017, DOI: 10.4236/aa.2017.72005
Abstract: This article adopts the paradigm that claims the non-disappearance of the ritual and ritual changes in modern and postmodern society. A wedding is an event in which a group of people speaks to itself and about itself. Images of the social structure and cultural content, of couplehood, family and personal and group identity surface through this cultural act. Weddings and their customs thus comprise a window through which the social values of a group can be observed, be it a modern or a traditional society. The anthropological study of the prenuptial rituals of immigrants from Georgia to Israel, and my experience with the ethnic pride of the celebrators, most of them young, lead me to conclude that these rituals serve as collective ethnic definitional ceremonies for them, where crossing between ethnicity, culture and identity takes place. The new ritual tradition in Israel fulfills an important role in the identity of the youths of this community and in the solidarity of the Georgian family and community. Tradition was processed anew and interpreted through the renewed ritual patterns, and became intertwined with modernity. A process of syncretism was thus created.

Clinical manifestations of human cytomegalovirus (HCMV) infection in children in the first few months of life
Aziza Khodjaeva
Medical and Health Science Journal , 2012,
Abstract: The research objective was to study frequency of antenatal infection and record probable clinical manifestations in 100 children with HCMV born from mother with HCMV in blood and mononuclear cells. The study identified poly-systemic internal organ damage in neonates due to prenatal HCMV. Research procedures involved study of 100 pairs of patients, Mother-Child tandem, using regular clinical assessment methods per algorithm and HCMV diagnostic methods: ELISA, affinity and avidity of HCMV antibodies, and HCMV genome identification via PCR method in blood plasma and mononuclear cells. Initial clinical disease manifested in 71% of children during late neonatal period. Children who died of HCMV (5%) were infected antenatal, and 39% were born prematurely. Embryonic stigma found in five cases. HCMV’s affinity to different tissues during the process of embryogenesis leads of poly-systemic damage and results in various clinical manifestations in the postnatal period. HCMV’s ability to invade mononuclear blood cells jeopardizes the antivirus defense system. The research is vital to deter the transmission of the virus and provide HCMV specific treatment to couples planning to have children.
CYTOMEGALOVIRUS INFECTION IN PREGNANCY AND THE FETUS: A CASE PRESENTATION
AZIZA KHODJAEVA
Medical and Health Science Journal , 2011,
Abstract: The objective of this case study was to study possible clinical manifestations of Human Cytomegalovirus (HCMV) which demonstrate the vertical transmission of HCMV from mother to her children. The patient, an HCMV infected woman with chronic socioeconomic problems and depression, was observed between 2003 and 2011. During that time, five pregnancies were clinically monitored with use of immunograms, PCR, and general blood and urine analyses. This case showed that HCMV infection of pregnant mother caused death of newborns due to HCMV(associated complications. Due to combinatory therapy the fifth pregnancy was successful with delivery of a HCMV asymptomatic newborn. With the deficit of knowledge on HCMV and its effect on pregnant women in Uzbekistan, such research for the clinical manifestation of the virus is vital to deter the transmission of the virus and improve the wellbeing of both mother and child.
Diauxic growth of Geotrichum candidum and Penicillium camembertii on amino acids and glucose
Aziza, M.;Amrane, A.;
Brazilian Journal of Chemical Engineering , 2012, DOI: 10.1590/S0104-66322012000200001
Abstract: the purpose of this work was to examine physiological differences between the yeast geotrichum candidum and the mould penicillium camembertii, organisms involved in the industrial process of cheese ripening. three groups of amino acids had previously been characterized, based on their carbon assimilation and dissimilation by the two fungal species. for both of them, a diauxic growth phase had been shown for a group of amino acids, which however had not been examined in light of physiological differences between the two microorganisms. in this work, the higher level of enzymatic activities of p. camembertii if compared to g. candidum was confirmed since a continuous and sequential use of both carbon substrates, glucose and arginine, was recorded during p. camembertii culture; while after glucose depletion, a clear stationary phase was recorded before the assimilation of the considered amino acid as both carbon and nitrogen sources by g. candidum. this behaviour was confirmed for the three amino acids tested, i.e., arginine, proline and glutamic acid. contrarily, during the two growth phases, on glucose and the test amino acid, respectively, higher growth rates were recorded for g. candidum compared to p. camembertii, showing higher substrate utilisation efficiency by g. candidum. improving the knowledge regarding the metabolization of amino acids might be helpful in designing strategies aiming at improving processes such as cheese ripening. the work should be followed up by similar works using small peptides.
Content Based Image Retrieval using the Generalized Gamma Density to model BEMD’s IMF.
Aziza Benkuider,Aarab Abdellah
Journal of Computers , 2011, DOI: 10.4304/jcp.6.6.1168-1174
Abstract: In this paper, we present a texture-image retrieval approach, which is based on the idea of to characterize images without extracting local features, by using global information extracted from the image Bidimensinal Empirical Mode Decomposition (BEMD) together with the Generalized Gamma (GG) Density. The BEMD method decompose image into a set of functions named Intrinsic Mode Function (IMF) and residue. The Generalized Gamma (GG) Density is used to represent the coefficients derived from each IMF and the Kullback-Leibler Distance (KLD) compute the similarity between Gamma Generalized function’s coefficients. The experimental results indicate that our approach can achieve higher retrieval rates.
Causes of diffuse alopecia in women

Indian Journal of Dermatology, Venereology and Leprology , 1994,
Abstract: Fifty female patients ranging in age between 14-45 years, complaining of a diffuse loss of hair for periods varying from 1-22 months were thoroughly interrogated to look for the factors leading to the hair loss. Laboratory investigations undertaken included a routine estimation of haemoglobin, ESR, urinalysis, examination of the stools, and any other test indicated by the history or examination. The hair loss was quantitated by asking the patient to collect all the fallen hairs during a 24 hours period for 7 consecutive days, and pack them into appropriately labelled polythene bags. Each collection was weighed to calculated the average daily loss. Such collections were repeated once a month for a period of 4-5 months to monitor the variations in the hair loss and study the effect for treatment. Ten hairs randomly picked from each collection were examined microscopically to look for any shaft abnormalities in addition to the examination of the root end and the distal end. The probable causes of hair loss in these patients were found to be psychologic stress in 21 cases, fever in 11 cases, child-birth/abortion in 5 cases, and a surgical operation in 3 cases. Some of these cases had more than one factor, while in 15 cases there was no clinical evidence of any of the known causes of hair loss. Routine laboratory investigations however revealed a haemoglobin level of less than 12 gm% in 25 cases, an ESR higher than 20 mm in 18 cases, asymptomatic urinary tract infection in 13 cases and gastro-intestinal parasites in stools in 12 cases. Thus every patient had at least one of the causative factors, while several patients had more than one factor which could be responsible for the hair loss. Almost all the cases in this group seemed to have telogen effluvium. Examination of the root end in most of the hairs showed a club hair, while the hair shaft revealed trichorrhexis in some of the hairs in 10 cases and trichoptilosis in 3 cases. Appropriate treatment normalised the hair loss which reflected in the collections of the fallen hair.

Computer Science , 2013,
Abstract: The domain of analysis and conception of Decisional Information System (DIS) is, highly, applying new techniques and methods to succeed the process of the decision and minimizing the time of conception. Our objective in this paper is to define a group of patterns to ensure a systematic reuse of our approach to analyse a DIS s business requirements. We seek, through this work, to guide the discovery of an organizations business requirements, expressed as goals by introducing the notion of context, to promote good processes design for a DIS, to capitalize the process and models proposed in our approach and systematize reuse steps of this approach to analyze similar projects or adapt them as needed. The patterns are at the same time the process s patterns and product s patterns as they capitalize models and their associated processes. These patterns are represented according to the PSIGMA formalism.

Abstract: Casablanca, Morocco's economic capital continues today to fight against the proliferation of informal settle- ments affecting its urban fabric illustrated especially by the slums. Actually Casablanca represents 25% of the total slums of Morocco [1]. These are the habitats of all deprived of healthy sanitary conditions and judged precarious from the perspective humanitarian and below the acceptable. The majority of the inhabi- tants of these slums are from the rural exodus with insufficient income to meet the basic needs of daily life. Faced with this situation and to eradicate these habitats, the Moroccan government has launched since 2004 an entire program to create cities without slums (C.W.S.) to resettle or relocate families. Indeed the process control and monitoring of this program requires first identifying and detecting spatial habitats. To achieve these tasks, conventional methods such as information gathering, mapping, use of databases and statistics often have shown their limits and are sometimes outdated. It is within this framework and that of the great German Morocco project “Urban agriculture as an integrative factor of development that fits our project de- tection of slums in Casablanca. The use of satellite imagery, particulary the HSR, has the advantage of providing the physical coverage of urban land but it raises the difficulty of choosing the appropriate method to apply.This paper is actually to develop new approaches based mainly on object-oriented classification of high spatial resolution satellite images for the detection of slums.This approach has been developed for mapping the urban land through by integration of several types of information (spectral, spatial, contextual ...) (Hofmann, P ., 2001, Herold et al. 2002b; Van Der Sande et al., 2003, Benz et al., 2004, Nobrega et al., 2006). In order to refine the result of classification, we applied mathematical morphology and in particular the closing filter. The data from this classification (binary image), which then will be used in a spatial data- base (ArcGIS).
