    Opis:
    A pot experiment was carried out under greenhouse conditions to study the impact of the evaluated treatments namely abamectin, azadirachtin 0.15%, azadirachtin 0.03%, Bacillus subtilis, Pseudomonas fluorescens, Paecilomyces lilacinus and oxamyl against root-knot nematode (Meloidogyne incognita) on the tomato plants cv. Super strain B. The results indicated that the most of the tested treatments obviously reduced root galls and remarkably increase tomato plant growth characters significantly and egg masses on root system, as well as, juvenile's numbers in the soil. P. lilacinus was the most effective treatment on both galls and egg masses achieving 88.23 and 76.94% reduction, respectively. While, less effective treatment was P. fluorescens achieving 57.53% galls reduction. Azadirachtin 0.03% was the least effective treatment giving 40.37% reduction of egg masses. The superior treatment that suppressed nematode populations was oxamyl recording (88.90%) followed by abamectin (78.69%) reduction. Moreover, azadirachtin 0.15% was the least effective treatment which recorded 60.15% reduction. On the other hand, plants free nematode recorded the highest plant parameters for shoot system length, fresh shoot weight, dry shoot weight and root system length with values of 24.15, 107.53, 211.59 and 46.17% increase, respectively. Azadirachtin 0.15% was the least effective treatment on shoot system length and fresh and dry shoot weight. While, oxamyl recorded the least increase in root system length estimated by 18.47%. B. subtilis recorded the highest increase in fresh root weight followed by P. fluorescens with value of 125.75 and 86.57%, consecutively. Vise versa, P. fluorescens was the superior treatment to increase the dry root weight by 68.14% followed by B. subtilis which recorded 35.40%. The least effective treatment in improving fresh root weight was azadirachtin 0.15% which recorded 54.85% increase. Regarding to dry shoot weight P. lilacinus and azadirachtin 0.15% were the least effective treatments with values of 8.85 and 2.66% reduction, respectively.

    Background. Low birth weight (LBW) is a major health problem responsible for neonatal mortality and morbidity such as diabetes, obesity and cardiovascular disease in adulthood. Objective. This case-control study aims to compare data on the intake of energy, macro and micronutrient in two groups of pregnant women, who gave birth to low birth weight (LBW) babies named cases and those who gave birth to babies of normal weight (NW) called controls. Material and methods. The collection of information was done using an established questionnaire for 400 pregnant women, allowing the collection of data on socio-demographic and obstetrical factors. Nutritional intake was obtained by recording food consumption using the 24-hour recall method. Anthropometric measurements of parturient and fundal height (FH) were measured before delivery. Results. The mean FH of the cases was 25.69±0.13 and that of the controls was 31.83±0.06. The gestational age of the cases was on average 31.65±0.21 week of amenorrhea (WA) against 38.04±0.08 WA for the controls. 37% of LBW newborns had an Apgar score < 7 (p< 0.001) and 71% were hospitalized in neonatal intensive care (p<0.001). Micronutrient deficiency was raised and concerned calcium 34.02% vs 60.65%, folates 48.32% vs 68.01% and iron 50.85% vs 66% in cases and controls respectively. Newborns from NW had a weight of 3395.5±15.99 against 1957.25±30.72 for those from LBW. Conclusion. This study shows that the nutritional intake did not cover all the nutrient needs of the pregnant women studied and that newborns with LBW are associated with an altered anthropometric status. Improving the living conditions of mothers, good monitoring of pregnancy, and good nutritional education can significantly improve the nutritional status with the same food intake and should be integrated into the nutritional intervention strategies.

    Background. Low birth weight (LBW) is considered to be one of the most important indicators of a newborn's chances of survival, and a major risk of medium- and long-term morbidity. Objective. To identify risk factors associated with low birth weight newborns among pregnant women during childbirth in Moroccan hospital environment with a view to proposing avenues of intervention for its prevention. Material and methods. Data concerning the weight of newborns at birth, nutritional education, pregnancy monitoring and other risk factors, etc. were collected from 312 pregnant women who gave birth in the maternity ward of El-Jadida Provincial Hospital in Morocco. Results. The study identified 156 cases of newborns with LBW and 156 controls of normal-weight newborns. After adjustment for the variables included in the analysis, the determined factors associated with LBW are nutritional education [OR: 6.22 (2.60-14.87), P<0.001], illiterate women [OR: 8.74 (1.65-46.08), P=0.011], insufficient pregnancy monitoring [OR: 5.69 (2.74-11.83),P<0.001], pregnant women with a normal weight [OR: 3.84 (1.73-8.52), P=0.001], lack of psychological support [OR: 3.23 (1.72-6.08), P<0.001] and tiring domestic activity [OR: 2.13 (1.14-3.99), P=0.017]. Conclusion. Promotion of nutrition for pregnant women, proper implementation of maternal health programs and improvement of their social condition are the modifiable factors that should help reduce LBW risk.

    Background. Micronutrient malnutrition is a serious public health problem in most developing countries, including Morocco, due to poor and therefore lower quality diets that lack dietary diversity. Objective. The present study aimed to assess dietary diversity and variety and their relationship with micronutrient adequacy in children and adolescents with type 1 diabetes (T1D). Materials and methods. A cross-sectional study was carried among 240 children and adolescents with T1D. Weight and height were measured and BMI was calculated. Dietary intake data were obtained from two 24-h recalls. A Dietary diversity (DDS) and dietary variety scores (DVS) and mean adequacy ratio (MAR) and nutritional adequacy ratios (NARs) were calculated and compared according to sociodemographic/anthropometric categories. Results. 52.1% of the patients were female. The mean age of the patients was 8.49 ± 4.1 years. The mean BMI was 19.44 ± 5.24 kg/m2; the mean DDS was 4.62±1.20 and the mean MAR was 0.66 ± 0.11. Older children living in rural areas have a low DDS/DVS. Parental education and income level are associated with DDS/DVS. General and central obesity were significantly elevated in children with high DDS. In addition, a high intake of vegetables, eggs, fiber and micronutrients (Magnesium, Calcium, Potassium, Zinc, Phosphorus and Vit B1) is associated with a high DDS; however, high DVS is associated with high consumption of dairy products, carbohydrates and low intake of protein and fat. There are also positive correlations between DDS/DVS and NARs for various nutrients. Conclusion. The quality of the respondents’ diets are moderately diversified. DDS or DVS can be used as indicators of micronutrient adequacy in Moroccan T1D children. Nutritional education needs to be strengthened to improve dietary diversity in children, especially in rural areas.

    Opis:
    Background. Currently, T1D is one of the most common chronic diseases in children and adolescents. The International Diabetes Federation (IDF) estimates that more than 1.1 million children and adolescents are living with (T1D). A few studies have evaluated the relationship between dietary intake and glycemic control (GC) in people with T1D, and in particular, children and adolescents. Objective. The aim of this study was to evaluate the relationship between anthropometric characteristics, lipid profile, inflammation, dietary intake and GC in comparison with international guidelines. Materials and methods. The study included a sample of 240 children, aged 15 years old or less with T1D. A structured questionnaire was used to collect information on the socio-demographic status, disease characteristics, and diet of the participants. Weight, height, and WC were measured and WHtR and BMI were calculated. Biochemical measurements were determined. Dietary intake was assessed using three 24-hour recalls. Results. Saturated fat intake was five times higher than recommended. Only 8.3% of participants reached the recommended level of fiber. Overweight, obesity, TC, TG, HDL and CRP were significantly higher in children with poor GC to those with good GC. In addition, participants with poor GC had significantly low intakes of calories, carbohydrates, fiber, MUFAs, and PUFAs and high intakes of fat and SFAs. The use of Bivariate correlation analyses showed that calorie, protein, fat and fiber intake were positively correlated with weight, height, WC, and GO, whereas carbohydrate intake was negatively associated with these parameters. On the contrary, CO showed a negative correlation with calorie, protein, fat and fiber intake and a positive correlation with carbohydrate intake. Conclusions. The results revealed that the dietary quality was poor and adherence to dietary recommendations was low with insufficient fiber intake and excess SFA. These results suggest that GC can be improved by a healthy, balanced diet by increasing fiber intake and limiting SFA intake.

    Background. Onset of overweight and obesity has been previously reported as a result of population migration to western countries. Objective. To determine the nutritional status, weight status and their association with socioeconomic status in sub- Saharan settled in El Jadida city in a Mediterranean country Morocco. Materials and methods. A descriptive study was carried out in 2018 on 256 sub-Saharans migrants living in the city of El Jadida in Morocco. Information on socio-economic and socio-demographic characteristics as well as anthropometric measurements was collected. The body mass index (BMI) and abdominal obesity by measuring waist circumference (WC) and waist circumference to hip ratio (WHR) and the distribution of body fat by calculating the sum of skin folds are determined. Results. Analysis results indicate that height, waist circumference, hip circumference, sum of trunk skinfolds, total sum of skinfolds, and BMI increase with age. The prevalence of underweight decreases with age, overweight was 38.7% in the youngest age group (18-25 years) and reached higher values after 35 years (44.10%). In addition, the prevalence of general obesity (based on BMI) increased with age and abdominal obesity (based on WHR and WC) was more marked in sub-Saharan people aged 26 to 35 years. These results also reveal the coexistence of underweight, overweight and obesity in all age groups. The analysis revealed a significant association between several variables and obesity. Significant associations were found between age and BMI (P=0.04), between level of education (university) and WHR (p=0.02), between sex and WHR, and between sex and WC (p=0.049). The study revealed also that the majority of the study sample gained weight after their settling in the host country. Conclusions. The study data show that obesity including overweight and abdominal obesity were prevalent among sub- Saharan migrants residing in the city of El Jadida. This prevalence is associated with socio-demographic and socio- economic factors.

    Opis:
    Ultrasonic pulse echo technique was used to study cupric oxide (CuO) thin films. CuO thin films were prepared using sol gel technique. They were doped with Lithium (Li) (1%, 2% and 4%). Thin films’ thickness (d) and band gap energy (Eg) were measured. In addition, elastic moduli (longitudinal (L), shear (G), bulk (K) and Young’s (E)) and Poisson’s ratio (v) were determined to estimate the microstructure properties of the prepared films. The study ameliorated the used transducers to overcome their dead zone and beam scattering; wedges were developed. The results showed the effectiveness of these wedges. They enhanced transducers’ sensitivity by changing the dead zone, beam diameter, beam directivity and waves’ transmission. Also, the study noted that Li doping caused the improvement of CuO thin films to be more useful in solar cell fabrication. Li-CuO thin films had narrower band gap. Thus, they acquired a high quantum yield for the excited carriers; also they gained more efficiency to absorb solar light.

    Background. The construction of the consumer’s identity is dependent on how they prepare their meals. Objective. Study the cooking methods, frequency, and duration of meal preparation in Moroccan households as well as the associated factors. Materials and methods. This work is a part of a study with a validated conceptual and methodological framework that was conducted in 507 households in the region of Rabat-Salé-Kenitra in Morocco. The characteristics of the population and data on the cooking methods, frequency, and duration of meal preparation were collected by a survey. Associations between variables were studied by univariate logistic regression with a significance level of p<0.05. Results. The majority of the population was aged between 35 and 65 years (76%) and lived in urban areas (70%). The univariate analysis showed that the urban area was a factor that hindered stewing (p=0.009), while the work status (p=0.04) and the marital status “Married” (p=0.04) were favorable factors; the household size (p=0.02) is a factor favoring steaming method; urban area (p=0.04), work status (p 0.03), nuclear family type (p<0.001), and household size (p=0.02) are factors hindering the use of oven cooking; urban area (p=0.02) and higher education level (p=0.04) are factors favoring the use of fried food, age category [20-34] years (p=0.04), higher education level (p=0.01) and work status (p=0.01) were factors that favored the use of grilling; nuclear family type, (p=0.04) and household size (p=0.03) were factors that hindered the preparation of breakfast; urban area (p=0.03) and Arab ethnicity (p=0.04) are factors hindering snack preparation; urban area (p<0.001) is a factor favoring dinner preparation; household size (p=0.01) and use of stewing at least four times a week (p=0.002) are factors hindering meal preparation time, while use of baking (p=0.01) is a favoring factor. Conclusion. The study results point towards the implementation of a nutritional education strategy based on combining habits, preferences, and good cooking practices.

    Background. The locations of food purchase have an impact on the quality of food consumed. Objective. To examine food purchasing habits at traditional and modern markets, their associated factors, and their effects on consuming natural and processed foods. Material and methods. This work used a validated conceptual and methodological framework of a study conducted among 507 households in the Rabat-Salé-Kenitra region in Morocco. Data on sociodemographic and economic characteristics and the frequency of food purchasing were collected from household representatives through a population survey. The food frequency questionnaire was used to collect frequency of consumption of 20 foods, including 10 natural and 10 processed. The associations between the variables were studied by the Chi-square test with a level of significance of p<0.05. Results. Among the households 70% were urban, 62% have nuclear families, 51.5% a size of 5 to 12 members, 41% middle standard of living, 87% frequented markets and souks (MS), and 19% frequented large and medium-sized stores (LMS) at least once a week. The households have in majority a frequency of natural foods consumption ≥ 3 times/week, including fresh vegetables (91%), olive oil (85%), and fresh fruit (84%); and processed foods, such as refined flours (68%), industrial cheese (65%) and industrial yoghurt (52%). MS and LMS frequentation were associated with environment (p<0.001), family type (p=0.01 and p=0.002, respectively), household size (p=0.04 and p=0.002 respectively) and standard of living (p<0.001). Foods whose consumption was associated with both MS and LMS frequentation included fresh vegetables (p<0.001) as natural foods and baked goods as processed foods (respectively, p=0.01 and p=0.04). Conclusion. The results of this study argue for implementing a nutrition education strategy based on the choice of food purchase locations as well as the consumption of natural or processed foods as part of a sustainable Mediterranean diet.

    Background. In recent decades, the Moroccan population has changed its dietary practices, particularly those related to meal-taking. It is about irregular meal schedules, reduced frequency and shorter time of meal-taking times, as well as a decrease in family meal-taking. All these factors are likely to influence its nutritional status. Objective. The aim is to study meal-taking practices, their determinants and their implications on weight status. In this study, meal-taking practices are defined by the regularity of the schedule, the frequency and the duration of the meals as well as the family commensality. Material and Methods. This work data are part of a study conducted among 507 households in the region of Rabat-Salé- Kenitra in Morocco, with a validated conceptual and methodological framework. The questionnaire was completed with one member of each household and the body mass index (BMI) was determined by an impedance meter. Results. The main results indicate that the majority of the surveyed population was aged 35 years (59%), female (52%), urban (70%), with a BMI ≥25 kg/m2 (51%), took usually three meals a day (89%), spent less than 90 minutes a day in meals and snacks (60%), had irregular meal schedule (69%), and usually eat at least two meals or snacks a day with family (49%). The univariate analysis showed that urban area was a factor favoring variations of meal times, the male sex was a factor favoring three meals a day, the level of higher education was a factor penalizing the daily duration of meals, and that marital status “married” was a factor favoring family commensality. In addition, variable meal times were revealed as a factor contributing to overweight/obesity, and meal times ≥90 min were revealed as a protective factor of overweight/ obesity. Conclusion. The study identified factors associated with meal times, frequency and duration. The results obtained will serve as a basis for the development of educational actions for a change in behavior conducive to health.

    Background. The use of validated and reliable methods and instruments is necessary to study dietary practices and nutritional status due to their direct impacts on population health. Objective. The aim is the validity and reliability of the conceptual and methodological framework of research on factors associated with dietary practices and nutritional status (FADPNS), carried out on adult population of the Rabat-Salé- Kenitra region in Morocco. Material and methods. First, we developed a conceptual and methodological framework for research on FADPNS, which aimed to study dietary practices, nutritional status, and the factors associated with them in an adult Moroccan population. Then, we studied the validity and reliability of this framework in three phases. Phase 1 focused on the validation of the content of the conceptual and methodological framework, Phase 2 focused on the study by an expert committee of the internal consistency validity (ICV) of the questionnaires used in this research , and Phase 3 consisted of the study of the reliability of the items questionnaires by the test of Cronbach Alpha. Results. Thus, the validated content of the conceptual framework of research on FADPNS includes socio-demographic, socio-economic, and socio-cultural characteristics; health status; physical activity, places of food purchase; food preparation, taking of meals, family commensality; social representations of good dietary practices; food consumption; and nutritional status. The questionnaires used in this research received an ICV score of 85%. The reliability test of the questionnaires showed a Cronbach Alpha value ≥ 0.5, which turned out to vary from "moderate" to "excellent". Conclusion. This work enabled the validation of the conceptual framework and the methodology of the study of the factors associated with dietary practices and nutritional status in the RSK region.

    Opis:
    The water quality of the open channels (Foughal, OumDhar and Tamagnounte) flowing into Beni-Mellal city were assessed in a bid to determine impacts of anthropogenic activities. Physicochemical and bacteriological parameters comprising temperature, pH, alkalinity, electrical conductivity, oxidizability, total hardness, ammonia, nitrite, nitrate, total coliforms, fecal coliforms and geochemical analyses were determined for the channels water before reaching the irrigation areas. While biological parameters demonstrated substantial variability, other parameters showed relatively little spatial variations. The spatial variations in water quality may be attributed to the effects of the urban wastewater discharge in the channels and to surface urban and agricultural runoff. Compared with drinking water quality standards of Moroccan and WHO, the results indicated that the channels water was suitable for drinking purpose with prior treatment. Various determinants such as electrical conductivity, residual sodium carbonate, total dissolved solids and hardness revealed that all water samples were suitable for irrigation.
    Oceniono wpływ działalności człowieka na jakość wody w otwartych kanałach (Foughal, OumDhar i Tamagnounte), dostarczających wodę do miasta Beni-Mellal. Zmierzono takie parametry fizyczne, chemiczne i bakteriologiczne, jak: temperatura, pH, alkaliczność, przewodnictwo elektrolityczne, utlenialność, twardość całkowitą, jony amonowe, azotyny, azotany, całkowitą liczbę bakterii coli, bakterie pochodzenia kałowego oraz przeprowadzono analizy geochemiczne w wodzie kanałów przed jej wprowadzeniem do systemów nawadniających. Podczas gdy parametry biologiczne wykazywały znaczną zmienność, pozostałe parametry cechowała stosunkowo niewielka zmienność przestrzenna. Na zmienność jakości wody w przestrzeni mogą wpływać ścieki miejskie spuszczane do kanałów oraz powierzchniowy spływ z terenów miejskich i obszarów rolniczych. Uzyskane wyniki porównane do norm jakości wody pitnej obowiązujących w Maroku i norm WHO pokazują, że woda w kanałach nadaje się do spożycia po wstępnym uzdatnieniu. Różne wskaźniki, takie jak przewodnictwo elektrolityczne, stężenie węglanu sodu, ilość całkowitej zawiesiny i twardość dowodzą, że analizowane wody nadają się do nawodnień.

    Opis:
    Kinetics of the polymerization of UO2 2+ ion to UO2[(OH)2UO2]4 2+ in the ammonia-uranyl nitrate system has been studied. The deepening of the color formed with the addition of ammonia made it possible to estimate spectrophotometrically the concentration of the formed UO2[(OH)2UO2]4 2+ ions in the solution at 420.6 nm. The effects of pH, temperature as well as the concentration of uranyl ion have been investigated. The reaction rate equation for the polymerization reaction is presented. Linear dependencies of logarithm of the apparent reaction-rate constant on both pH and the reverse of temperature were observed.
