Le numérique à l’épreuve de l’écologie
Authors: Ngoc Anh , MELLOT Sandra , PRODHOMME Magali
Published: May 2022

Dans l’optique d’examiner la question de la « culture du numérique », ce travail propose un regard critique de la fabrique de l’émergente norme de « sobriété numérique ». Par une analyse généalogique et discursive, nous montrons, à travers cette fabrique, un processus complexe de « cultiver » le numérique pervasif qui s’impose aujourd’hui comme un « milieu ». Inscrite dans un nouvel imaginaire social marqué par l’avènement d’un « hyperbien écologique » contemporain, cette norme s’est avérée produite par multiples acteurs des sphères différentes (intellectuels, société civile, politiques). Mais, en tant que construit culturel, la « sobriété numérique » circule dans une logique de réénonciation permanente à travers ces divers espaces sociaux. Sa fabrique révèle une tension que cette norme vise à concilier : celle entre l’hyperbien écologique et l’hypersystème numérique, entre Homo Ecologicus et Homo Numericus.

Solid phase synthesis is the most dominant approach for the synthesis of biological oligomers as it enables the introduc-tion of monomers in an iterative, reproducible manner. Solid phase synthesis of oligosaccharides is crucial for the devel-opment of glycobiology. Accelerated solid phase synthesis of biological oligomers is crucial for chemical biology, but its application to the synthesis of oligosaccharide is not trivial. Solid phase oligosaccharide synthesis is performed in a variety of conditions and temperatures, requires inert gas atmosphere, and demand high excess of glycosyl donors. The reactions are usually very long, and the poor mixing of the solid support increases the risk of diffusion-independent hydrolysis of the activated donor. The entire process is slow and done mostly in special synthesizers. High shear stirring is a new con-cept in solid phase that enables shortening the synthesis time. The efficient mixing makes sure that reactive intermedi-ates can diffuse faster to and into the solid support thereby increase the kinetics of the reactions. We report the first stir-ring-based accelerated solid-phase oligosaccharide synthesis. We harnessed high shear mixing to promote diffusion-dependent glycosylation over diffusion-independent side reactions resulting in high conversion in short reaction time. We eliminated the need for high excess of glycosyl donors and overcame the need to use inert atmosphere. We showed that by tailoring the deprotection and glycosylation conditions to the same temperature, all steps are performed continuously and full glycosylation cycles is completed in few minutes
Double-Lariat Caged Morpholino Oligonucleotides for Optical Gene Silencing
Authors: Pattanayak Sankha , Deiters Alexander , Chen James
Published: May 2022

Caged morpholino oligonucleotides (cMOs) are synthetic tools that allow light-inducible gene silencing in live organisms. Previously reported cMOs have utilized hairpin, duplex, and cyclic structures, as well as caged nucleobases. While these optochemical technologies enable efficient optical gene silencing, they can have limited dynamic range. To address this issue, a new caging strategy was developed where the two MO termini are conjugated to an internal position through a self-immolative trifunctional linker, thereby generating a bicyclic cMO with a double lariat-like structure. The efficacy of this alternative cMO design has been demonstrated in zebrafish embryos and compared to the monocyclic constructs.
The Geographic Effects of Monetary Policy
Authors: Herreño Juan , Pedemonte Mathieu
Published: May 2022

We study the differential regional effects of monetary policy exploiting geographical heterogeneity in income across cities in the United States. We find that prices and employment in poorer cities react more to monetary policy shocks. The results for prices hold for a wide range of narrow consumer expenditure categories. The results are consistent with New Keynesian models that allow for a differential share of hand-to-mouth consumers across regions, but not with models in which regions have different slopes of the Phillips curve. We show that an increase in heterogeneity across cities amplifies the effect of monetary policy on prices and employment.

Published: May 2022

Ventilators are one of the medical devices that are needed as a breathing apparatus for COVID-19 patients who have respiratory problems. One of the low-cost ventilators currently being developed by several domestic institutions is the ambu bag-based ventilator. The point is an air bag (bag) that is pressed by two carefully controlled automatic clamps, so that it can reach all, while taking into account portability, aesthetics and ease of manufacture. Therefore, the Bag Valve Mask (BVM) or ambu bag is an emergency option to replace the function of the ventilator. This study aims to make an ambu bag that can be applied as a portable mechanical ventilator. Thus, the ambu bag which was originally used manually can be used automatically like a ventilator machine in general. In determining the type of mechanical arm pressure, several parameters such as minute volume, respiratory rate, and tidal volume are used. As recommended by the American Heart Association (AHA) that the tolerance limit for the RR value is +/-10 BPM, it can be said that the automatic BVM as a result of this study can be used with or without a reservoir as needed or with the addition of oxygen

Kepmenkes No.129/Menkes/SK/II/2008 concerning Minimum Hospital Service Standards (SPM) states that as much as 20% of food leftovers are not eaten by patients. Patient nutrition becomes inadequate and inefficient due to wasted costs. This study aims to analyze food waste from inpatients at the hospital. Using a cross-sectional design, measurements were made of 113 inpatients at Ahmad Yani Metro Hospital, taken proportionally from classes I, II, and III with the consecutive method. As the dependent variable is leftover food and the independent variable is food appearance (portion and serving), food taste (seasoning and food temperature), and food from outside the hospital. Data were collected by interview technique using a closed list of questions and assessment using the Comstock Form. The analysis will be carried out to the bivariate level using a t-test. The results of this study indicate that 79.6% of inpatients at the Ahmad Yani Hospital in Metro City left less than 20% of food left. Meanwhile, the average leftover food reached 18.5% (SD=14.7%). There was a relationship between food presentation (p-value=0.018), food temperature (p-value=0.048), and food from outside the hospital (p-value= 0.044) with leftover food. Meanwhile, the portion of food (p-value=0.178) and seasoning (p-value=0.115) had no significant relationship with food waste. Therefore, it is recommended to hospitals as nutrition service providers improve the vegetable menu in the menu cycle.

Based on BPS data in 2017, around 25 million Indonesians still defecate openly. Many factors influence the ownership of latrines, but research related to factors of employment, family monthly income, and support from community leaders for latrine ownership in Aceh Barat Daya Regency is still rarely done. This study aimed to determine the relationship between employment, family monthly income, and support from community leaders on latrine ownership. This cross-sectional study with a sample of 100 respondents who were randomly selected and scattered in sub-districts was conducted in the urban area of Aceh Barat Daya Regency, Nanggroe Aceh Darussalam province. Questionnaires related to respondent characteristics, employment, family monthly income, and support from community leaders, as well as latrine ownership, were collected directly by the researchers through face-to-face interviews from September-October 2021. The statistical tests used were Chi-Square and Mann-Whitney with a significance level of p-value<0.05. The results showed that there was no significant relationship between employment (p-value=0.604), family monthly income (p-value=0.118), and support from community leaders (p-value=0.615) on latrine ownership. In conclusion, there is no relationship between employment factors, family monthly income, and support from community leaders for latrine ownership in Aceh Barat Daya District, Nanggroe Aceh Darusalam province. Village to district governments can offer policies that ensure that every house, owned or rented, must be equipped with proper sanitation facilities.

Analyzing energy deprivation for cooking in Argentina and Brazil
Authors: Ibánez-Martín María , Melo Yormy Eliana , Zabaloy María Florencia
Published: May 2022

Lack of access to clean cooking is one dimension of energy poverty that has called the attention of many international organizations and policymakers, due to the relevance of cooking, as an energy service, in the satisfaction of essential needs. The present paper has two central objectives: it intends to characterize the population with energy deprivation for cooking and detect if their characteristics are coincident in Brazil and Argentina, and it analyses whether the selection of traditional fuels for cooking is related to the presence of other socioeconomic deprivations. To fulfill these objectives, an analysis of descriptive statistics is performed, and logistic models are estimated during the period 2004-2014. From the descriptive analysis, it is found that the socioeconomic characteristics of the population that presents energy deprivation in cooking are markedly different from those that are not deprived in this dimension. In turn, there is a strong dependence between the multidimensional deprivations and energy poverty in cooking.

Numerical Analysis of the Carrying Capacity of a Piled Raft Foundation in Soft Clayey Soils
Authors: Ahmed Danish , Bt Taib Siti Noor Linda , Ayadat Tahar , Hasan Alsidqi
Published: May 2022

Piled raft foundations are a common type of foundation for high-rise buildings. Unlike shallow foundations, deep foundations (piles) pass through weak or soft soil deposits and can reach stiff soil or bedrock to support the weight of the structure. In this paper, the performance of a medium embedment depth piled raft foundation in soft soil is presented. A numerical model was developed and a parametric study was conducted in order to simulate the case of such a foundation system and to investigate its performance in soft clay. This parametric study investigated the effect of the geometry of a piled raft foundation and the stiffness ratio between the pile material and clay on the performance of the foundation system in soft soil. Additionally, the failure mechanism of such a foundation system under load was examined. An analytical model was developed to predict the ultimate carrying capacity based on the observed failure mechanism. A semi-empirical model is proposed for determining the Improvement Factor (IF) of a given soil, pile, and geometric condition. Findings of the study indicate that the performance of piled raft foundations on soft soils is significantly affected by the piles’ spacing. As the ratio S/D increases, the ultimate carrying capacity of a piled raft foundation decreases. However, when this ratio exceeds 10 (S/D> 10), piles have little or no effect on the ultimate carrying capacity of this foundation system. A piled raft foundation system fails by bearing at the base of the piles and also by shear at the side of the pile group on hyperbolic plans. Doi: 10.28991/CEJ-2022-08-04-01 Full Text: PDF
The Effects of Spillway Width on Outflow Discharge and Flow Elevation for the Probable Maximum Flood (PMF)
Authors: Sutopo Yeri , Utomo Karuniadi Satrio , Tinov Naufal
Published: May 2022

The purpose of this study was to analyze the effect of spillway width on flow elevation at the weir crest based on the flood discharge design for the Probable Maximum Flood (PMF) return period using flood routing hydrologically at the Cacaban Dam (Indonesia). The rainfall Probable Maximum Precipitation (PMP) design uses the Hershfield Equation. The design of the flood discharge analysis of QPMF used the Nakayasu Synthetic Unit Hydrograph (HSS). Flood routing uses the hydrologic routing method. The Cacaban Dam is located in Jati Village, Kedung Banteng District, Tegal Regency, Central Java Province, Indonesia. The results of the research data analysis showed that increased spillway crest widths led to decreased flow evaluation at the spillway crest, and increased outflow discharge. Thus, if a large storage volume of the reservoir is intended, then the width of the spillway crest must be reduced. Otherwise, the width of the spillway crest must be increased. In terms of flood control in the Tegal Regency, it's better to make the crest of the spillway smaller. Doi: 10.28991/CEJ-2022-08-04-08 Full Text: PDF
Behavior of Reinforced Concrete Deep Beams with Openings under Vertical Loads Using Strut and Tie Model
Authors: Mabrouk Rasha T. S. , Mahmoud Mahmoud A. S. , Kassem Magdy E.
Published: May 2022

This research aims to study the effects of the size and location of openings on deep beams. The analysis of deep beams with openings presents a rather complex problem for engineers, as there are currently no guidelines within the design codes for this problem. Using the strut and tie model is a feasible solution, but also gives some uncertainties due to the various models that can be used. This paper proposes using a strut and tie model for the deep beams with openings where reinforcement is laid out in the form of embedded struts and ties. The study is divided into an experimental and a numerical part. The experimental study was conducted on eight reinforced concrete deep beams under vertical loads. Seven of the beams had web openings of different sizes and locations, while the eighth specimen was a reference beam without any openings. The beams had the same concrete dimensions with the size of the openings in the web taken as 150 150 mm and 300 300 mm, and the location of the opening in the horizontal direction was varied between 0.11 to 0.4 the span. The experimental results were analyzed in terms of cracking pattern, mode of failure, and load-deflection behavior and then compared to numerical analysis conducted using a finite element program. A parametric study followed to investigate the influence of reinforcement arrangement and reinforcement around the openings on the behavior of deep beams. The results showed that large web openings that directly interrupted the compression strut had the most reduction in beam capacity and that the location of the opening did not significantly affect the strength of the beam in the case of small openings. Doi: 10.28991/CEJ-SP2021-07-011 Full Text: PDF

Published: May 2022

Trigonella persica is a valuable medicinal plant which comprises trigonelline that is secondary metabolite and important component in cosmetic and medicine. This research was conducted in order to evaluation the drought stress effect on growth parameters, root anatomical changes and trigonelline content in T. persica. Plants were grown under soil moisture corresponding to 100%, 75%, 50% and 25% field capacity for two weeks. The data showed that drought stress was significantly decreased fresh weight and dry weight of shoot and root. In addition, leaf area was declined due to drought stress. Interestingly, root length was enhanced by drought stress. Root microscopic study demonstrated that drought stress increased thickness of epidermal, endodermal, vascular bundle, central cylinder and parenchyma in T. persica. Drought stress caused a significant increment in alkaloid and trigonelline content in aerial parts and roots of T. persica. These results revealed that T. persica responded to drought stress by increasing the alkaloid and trigonelline, as well as the anatomical changes in root. Considering the importance of trigonline and alkaloids, this work may open prospects for production of the pharmaceutically valuable secondary metabolites thereby drought stress.

Different types of spices used daily have been documented to have antimicrobial and medicinal value as well. Most bacteria are sensitive to the extracts from plants such as, garlic, onion, thyme and turmeric etc. Spices such as these have been used as antimicrobial agents in their raw form for the treatment of wounds, injuries and joint pains etc. The present study was conducted to investigate the antibacterial activity of these natural spices. Different concentrations of extracts were prepared by using two solvents; water and ethanol, the test organisms used were Escherichia coli and Staphylococcus aureus. All the spices used were effective against the test organisms, but the best activity was shown in garlic, while the least activity was shown in thyme, in general, the ethanolic extracts were more reactive than the aqueous extracts. Natural spices could be a potential source for antimicrobial agents. Validation of natural spices as alternative and complementary medicine can be achieved by several in vivo trials through which the safe use of such products can be assured. This study emphasizes the therapeutic potential of spices and the need to enhance its exploitation on this regard.

This study evaluated the anti-microbial and anti-inflammatory properties of ethanol extract of Allium sativum linn. The ethanol extract yielded two distinct layers which differed in phytochemical composition, anti-microbial and anti-inflammatory properties. In the base filtrate (BF), tannins, carbohydrates, alkaloids, glycosides, reducing sugars, flavonoids, saponins, acidic compounds and resins were found present. The methanol fraction of the base filtrate was however found to have resins and tannins. The acute toxicity (oral) in this study was 3,750 mg/kg. Anti-microbial activity was tested using clinical isolates of Staphylococcus aureus, Streptococcus pneumonia, Escherichia coli, Salmonella typhi, and Klebsiella pneumonia, with Penicillin-G, Erythromycin, Gentamicin, Ciprofloxacin and Ceftriazone as standard drugs. The upper filtrate and base filtrate of the extract were found to exhibit a statistically significant and dose-dependent inhibitory effect on all test micro-organisms when compared with control. The result of the systemic anti-inflammatory study showed that the extract had a statistically significant, dose and time dependent systemic anti-inflammatory effect when compared with the negative and positive controls. The topical anti-inflammatory study showed a statistically significant, dose and time dependent topical anti-inflammatory effect at all tested doses. In conclusion, this study was able to establish that extract of Allium sativum had a statistically significant (p< 0.05) anti-microbial and anti-inflammatory effects, which is comparable to standard anti-microbial and anti-inflammatory drugs. This pharmacological effect may be due to the abundant presences of phytochemical constituents in the ethanol extract of Allium sativum L. This goes a long way to support its extensive use as an anti-microbial and anti-inflammatory agent in ethno medicine.

The noticeable lack in macroalgae number and their vegetation composition in the Suez Canal district may refer to the importance of studying and following the temporal and spatial patterns that are in change in space and time. Therefore, we have to follow regular biodiversity monitoring to elucidate the changes to seaweed vegetation in the Suez Canal area that might occur as seasonal variations or anthropogenic impacts. The present study extended from summer 2020 to spring 2021 along the Suez Canal district, including eight sites at Port Said on the Mediterranean Sea, Timsah Lake in Ismailia and Suez Bay in the Red Sea. Distribution of seaweeds is usually affected by environmental factors as temperature, salinity, pH, and water chemistry. Most of the chemical parameters recorded very high concentrations (high significant) at the sites in the Suez Bay area during all seasons, excluding nitrogen and phosphorus, which were elevated recordings in the Port Said area. El-Timsah Lake area recorded an increase in salinity which was considered as a brackish stratification type. The taxonomic groups of the recorded species showed a total of 39 macroalgal taxa (20 Chlorophyta, 16 Rhodophyta and 3 Phaeophyta). Port Said area recorded the highest significant number of Chlorophyta and Rhodophyta communities. The relative abundance of macroalgal divisions was Chlorophyta, which formed the main coverage. Enteromorpha-Ulva community was characterized during all the study seasons. Multivariate analysis showed the great relation between seaweed distribution, physicochemical parameters and seasonal variations.
Scattering power decomposition-based analysis for target identification

Reflection and non reflection symmetry conditions can be fitted in the scattering models to optimize the coherence power estimation. The SAR formed from received wave is in the form of images which captures the physical feature of the target under consideration. To cohersely extract the target characters prominently the co polarization parameters are considered in the design model. In this investigation a new modified approach with the co polarization parameters is developed. The scattering component and the associated power components computed from the design model illustrate quantitatively a better confidence in evaluating the target. The components namely surface power component, volume power components and double bounce power components are obtained from the scattering parameters. The formulated algorithms model used in decomposition technique gives positive scattering powers. The technique is applied on C band RADARSAT2 images and simulated using a system level mathematical model.

Published: May 2022

Background: Stunting has a detrimental influence on the health and development of children and has a number of negative consequences, including an increase in mortality as a result of a loss in bodily immunity, which makes youngsters more susceptible to illness. Additionally, there are impairments in cognitive capacities, as well as learning and productivity in adulthood. Stunting prevalence is relatively high in Indonesia, at 30.8%, compared to the global prevalence of 22.2%. Stunting children tend to have protein energy malnutrition (PEM) condition, which can lead in salivary gland atrophy, decrease sIgA levels, and disrupting the buffering system, cleansing, and antibacterial agents. It is able to increase the risk of dental caries. The purpose of this review is to determine whether salivary sIgA levels can be used to predict the risk of developing caries in stunted children.

The study on heavy metals was conducted at the Ogbujilekwe stream watershed. The study aimed to ascertain the heavy metal content of the watershed and the water from the nearby stream and to find out if there is any relationship between the heavy metals in the watershed and that in the waters sample. The experiment was laid out using Randomized Complete Block Design. The heavy metals that were investigated in this research work are Copper (Cu), Mercury (Hg), Lead (Pb) and Zinc (Zn). The result of mean values of the heavy metals shows that the heavy metals were significant and Cu followed by Hg was the most significant at p< 0.005. Also, Hg in soil was above the permissible limit for soil samples. Results from the mean values of the water samples also showed that all the heavy metals were significant in water, and mercury was the most significant heavy metal. From correlation analysis of the heavy metals in soil and water, only mercury in the soil had a positive correlation with mercury in water, and an increase in other heavy metals in the water had no relationship with the watershed. The mercury pollution in the water can therefore be attributed to the discharge from the watershed.
