Abstract
Background
Secondhand smoke (SHS) exposure gained lesser interest than active smoking. There is evidence from previous studies that SHS exposure had negative effects on fetal growth. This study aimed to examine the effect of smoke exposure on pregnancy outcome and to evaluate the level of nicotine urinary end-product cotinine in pregnant women in the late trimester. We included 36 women with a history of SHS exposure and 48 women without a history of exposure; all were in last trimester of pregnancy. We measured cotinine level in urine and followed the two groups until delivery and recorded fetal outcomes. Fetal biophysical parameters and blood flow waveforms were measured using B-mode and Doppler ultrasonography, respectively.

Results
The total range of the urinary cotinine creatinine ratio (CCR) concentration in the SHS exposed pregnant women was 0.01–0.2, IQR = 0.18 ng/mg.cr, versus 0.01–0.1, and IQR = 0.03 ng/mg.cr in the non-exposed group. The mean value as well as the mean rank of CCR was significantly higher (0.1 ± 0.08 ng/mg.cr., 40.3 respectively) in the exposed pregnant women as compared to the non-exposed pregnant women ((0.04 ± 0.02), 29.3 respectively, p value < 0.05). Newborn of the exposed women had significantly low birth weight which negatively correlated with cotinine level and had a dose-response relationship.

Conclusions
SHS exposure had negative effects on fetal outcomes. Efforts should be utilized to increase awareness of the consequences of secondhand smoke on the fetus and strict follow-up of exposed women for early detection.
Microbial influences on gut development and gut-brain communication
Authors: Ye Lihua , Rawls John F. 
Published: November 2021

ABSTRACT
The developmental programs that build and sustain animal forms also encode the capacity to sense and adapt to the microbial world within which they evolved. This is abundantly apparent in the development of the digestive tract, which typically harbors the densest microbial communities of the body. Here, we review studies in human, mouse, zebrafish and Drosophila that are revealing how the microbiota impacts the development of the gut and its communication with the nervous system, highlighting important implications for human and animal health.
MEMORI, TRAUMA, DAN UPAYA REKONSILIASI PERANG TELUK II DALAM NOVEL SĀ’ATU BAGDĀD KARYA SYAHAD AL-RĀWIY
Authors: Arofah Arofah , Arif Rokhman Muh. 
Published: November 2021

Sā’atu Bagdād (2016) is a novel by Syahad al-Rāwiy which captures the dark events of Gulf War II which involved Iraq, Kuwait, the United States, and the United States coalition countries that began in 1990. This novel is divided into two parts, namely the past relating to the life of the main subject during Gulf War II and the future related to post-war life. The problem in this research is how the author reconstructs the memory and trauma that causes the subject's psychological shock and how the subject makes reconciliation efforts on the memory and trauma that befell him. To study this, the analytical descriptive method and the theory of Halbwachs memory, Caruth's trauma, and working through LaCapra were used. The results of this study indicate that the incident of Gulf War II is a personal traumatic memory that becomes the collective memory of the Iraqi people. Traumatic memories are narrated in the events of bunker protection in 1991, embargo sanctions, and subsequent war. The overlapping event caused the subject to experience back trauma, such as flashbacks, war phobia, and diaspora simulations. As for reducing the memory and trauma that continues to rage, the subject does the working-through in two ways: first, efforts to distance and let go of the past through diasporic experience and synchronizing with the new world, and second, to testify by writing novels and finding the right partner.

Published: November 2021

Face à la situation hors du commun provoquée par la pandémie de 2020, les milieux scolaires se sont adaptés rapidement pour offrir l’enseignement à distance au primaire et au secondaire. Comment cette situation a-t-elle été vécue par les enseignants ? Quels ont été les impacts sur leur enseignement ? Cet article propose de partager quelques réflexions autour de ces questions, issues d’une entrevue menée avec deux conseillères pédagogiques en mathématiques. Nous constatons notamment que le changement brusque des modalités d’enseignement lève le voile sur des problèmes plus profonds, ne nous laissant pas d’autre choix que « de déterrer de vieux squelettes ».

Published: November 2021

When presented with a periodic stimulus, humans spontaneously adjust their movements from reacting to predicting the timing of its arrival, but little is known about how this sensorimotor adaptation changes across development. To investigate this, we analyzed saccade behavior in 114 healthy humans (ages 6–24 years) performing the visual metronome task, who were instructed to move their eyes in time with a visual target that alternated between two known locations at a fixed rate, and we compared their behavior to performance in a random task, where target onsets were randomized across five interstimulus intervals (ISIs) and thus the timing of appearance was unknown. Saccades initiated before registration of the visual target, thus in anticipation of its appearance, were labeled predictive [saccade reaction time (SRT) < 90 ms] and saccades that were made in reaction to its appearance were labeled reactive (SRT > 90 ms). Eye-tracking behavior including saccadic metrics (e.g., peak velocity, amplitude), pupil size following saccade to target, and blink behavior all varied as a function of predicting or reacting to periodic targets. Compared with reactive saccades, predictive saccades had a lower peak velocity, a hypometric amplitude, smaller pupil size, and a reduced probability of blink occurrence before target appearance. The percentage of predictive and reactive saccades changed inversely from ages 8–16, at which they reached adult-levels of behavior. Differences in predictive saccades for fast and slow target rates are interpreted by differential maturation of cerebellar-thalamic-striatal pathways.SIGNIFICANCE STATEMENTFrom the first moments of life, humans are exposed to rhythm (i.e., mother's heartbeatin utero), but the timeline of brain development to promote the identification and anticipation of a rhythmic stimulus, known as temporal prediction, remains unknown. Here, we used saccade reaction time (SRT) in the visual metronome task to differentiate between temporally predictive and reactive responses to a target that alternated at a fixed rate in humans aged 6–24. Periods of age-related change varied little by target rate, with matured predictive performance evident by mid-adolescence for fast and slow rates. A strong correlation among saccade, pupil, and blink responses during target prediction provides evidence of oculomotor coordination and dampened noradrenergic neuronal activity when generating rhythmic motor responses.

Background Many children encounter unusual or “exaggerated” reactions such as large local, atypical or systemic reactions after mosquito bites.
Objective The aim of this study was to document the clinical features of children with mosquito allergy and investigate the possible associations between demographic features and type of reactions in this population.
Methods Children with large local or unusual reactions after mosquito bites who attended to our outpatient pediatric allergy department were enrolled in the study along with control subjects.
Results A total of 180 children (94 with mosquito allergy and 86 age and sex-matched control subjects) with a median age of 6.8 years (IQR 5.5–9.3) were enrolled. Atopy (35.1% vs. 11.6%, p < 0.001) and grass pollen sensitization (28.7% vs. 8.1%, p < 0.001) were significantly more frequent in children with mosquito allergy. Skin prick test with mosquito allergen was positive in only 6 children (6,4%). Grass pollen sensitization was most common in children (28.7%) followed by sensitization to house dust mite (9.6%). 30 children (31.9%) had an accompanying atopic disease such as allergic rhinitis, asthma or atopic dermatitis. Bullae were significantly more frequent in children with asthma (41.7% vs.15.9, p = 0.034). The median duration of symptoms after onset were significantly longer in patients with ecchymosis, with immediate wheals and in children whose symptoms start in 20 min to 4 hours after mosquito bites.
Conclusion There is an association between unusual, large local or exaggerated reactions after mosquito bites and allergic diseases in children. The severity of reactions increases with age and particularly in children with atopic background.

Published: November 2021

Early detection of faults in DC motors extends their life and lowers their power usage. There are a variety of traditional and soft computing techniques for detecting faults in DC motors. Many diagnostic techniques have been developed in the past to detect such fault-related patterns. These methods for detecting the aforementioned potential failures of motors can be utilized in a variety of scientific and technological domains. Motor Power Pattern Analysis (MPPA) is a technology that analyzes the current and voltage provided to an electric motor using particular patterns and protocols to assess the operational status of the motors without disrupting production. Engineers and researchers, particularly in industries, face a difficult challenge in monitoring spinning types of equipment. In this work, we are going to explain how to use the motor power pattern/signature analysis (MPPA) of a power signal driving a servo to find mechanical defects in a gear train. A hardware setup is used to simplify the demonstration of obtaining spectral metrics from the power consumption signals. A DC motor, a set of metal or nylon drive gears, and a control circuit are employed. The speed control circuit was eliminated to allow direct monitoring of the DC motor's current profiles. Infrared (IR) photo-interrupters with a 35 mm diameter, eight-holed, standard servo wheel were employed to gather the tachometer signal at the servo's output. The mean value of the measurements was 318 V for the healthy profile, while it was 330 V for the faulty gears power data. The proposed power consumption profile analysis approach succeeds to recognize the mechanical faults in the gear-box of a DC servomotor via examining the mean level of the power consumption pattern as well as the extraction of the Power Spectral Density (PSD) through comparing faulty and healthy profiles

Based on the study results, this paper reports a technology to produce natural fruit and berry pastila and marmalade of improved nutritional and biological value with a long shelf life. Critical control points of product safety have been identified and scientifically substantiated. The technological process to prepare pastila and marmalade involves exposing the raw materials to high and low temperatures while maintaining certain indicators of the content of dry substances. The identification feature of marmalade products is the content of a certain type of fruit raw materials, which poses risks throughout the life cycle of product manufacturing despite the fact that the preparation and storage of the raw materials implies the temperature range from 0 °C to minus 15 °C. Problematic issues of mold occurrence have been considered. It was established that the moisture content in the product above 15 % leads to an increase in the content of mold fungi and significantly reduces its shelf life. This paper gives the results of a study to identify the preservation of vitamin C in products prepared from fresh berries and from berries subjected to freezing. It was revealed that in the process of storing the raw materials at a temperature of minus 15 °C, the amount of vitamin C in the resulting product decreased by 11.3 % compared to the product prepared from fresh raw materials. The maximum limit of the high preparation temperatures of 108 °C did not significantly affect the loss of vitamin C. Studies were conducted to determine the sugar content in products whereby a high fructose content was identified. Critical control points at all stages of production were determined, which has made it possible to choose the optimal technological modes and parameters for the safety and quality of the product

Published: November 2021

This paper reports a study of the air medium where welding processes take place, with special attention paid to the evolution of carbon monoxide (CO) in the working medium in the process of gas welding. Plots were constructed and polynomial dependences were obtained to show a change in the concentration of carbon monoxide in the air of the working area during gas welding.
It was confirmed experimentally that the concentration of carbon monoxide exceeds the permissible sanitary and hygienic indicators MPC (20 mg/m3) during gas welding. As a result of the experiment, the effectiveness of the use of an additional device was proven, namely an umbrella gas concentrator, in order to capture welding gases that are formed during gas welding. It was established that the MPC is exceeded under certain working conditions and welding wire. The carbon monoxide formation during gas welding was analyzed; these processes were compared with electric arc welding. The mathematical dependences derived make it possible to assess the risks of the welders’ work and conclude that the electric arc welding is characterized by a much higher rate of CO evolution from the beginning of the welding process (8.5 mg/s), that speed then decreases over 20 s by 2 times (to 4.5 mg/s). In 90 s, the speed becomes constant, to 2 mg/s. In comparison, gas welding has almost the same rate of CO formation, namely 0.3–0.9 mg/s.
By changing the types of welding wires used in gas welding and taking into consideration the type of material that needs to be welded (including the period of its use), it is possible to influence the volume of CO emissions entering the working area and an employee’s respiratory area

A formulation composition and a low-temperature technique have been devised for concentrating fruit and vegetable puree with the following component content: 20 % apple; 20 % pumpkin; 15 % beets; 15 % cranberries; 15 % hawthorn. The puree is concentrated in a rotary evaporator to a solids content of 50 % at a temperature of 50...56 °C under vacuum. The processing time was reduced to 1...2 min, which is several times less compared to conventional single-case pump vacuum evaporators (60...90 mins). Reducing the temperature influence of concentrating contributes to an increase in the organoleptic and physicochemical parameters of the resulting paste. To determine the effect of the contribution of each component to the structure of the paste, the structural and mechanical properties of the puree from each raw material and concentrated semi-finished products were investigated. The devised paste has an increased strength of the structure with a dynamic viscosity value of 394 Pa⋅s, which is 2.5 times more than that in the control sample. The devised blended fruit and vegetable paste has an increased content of physiologically functional ingredients and good organoleptic parameters, unlike control (apple paste).
It was established that the partial replacement of apple puree in the formulation composition of marshmallow with 75 % of the devised multicomponent fruit and vegetable paste gives the product original properties. The dynamic viscosity value of the marshmallow in which 75 % of apple puree was replaced with the devised paste has increased, compared to the control sample (marshmallow without additives), from 408 Pa⋅s to 908 Pa⋅s. The color of the marshmallow mass where 75 % of apple puree were replaced is bright pink with a wavelength of 596.7 nm and a brightness of 62.3 %. The data reported here make it possible to improve the quality of original marshmallow products when adding fruit and vegetable semi-finished products whereby an increase in functional properties is provided

Published: November 2021

Pumpkin seed protein is a high-quality plant protein, which has all essential amino acids for the human body and can also supply essential amino acid histidine for children. When it is introduced to food products, it needs to meet some functional properties, such as solubility, emulsifying ability, foaming ability, and so on. Among them, solubility is very important because it has a great influence on other functional properties of protein. In this study, pH-shifting treatment, which is a novel method to modify protein, is applied to improve the solubility of pumpkin seed protein isolate (PSPI). PSPI treated by pH-shifting treatment was investigated at different pH values (pH 2, pH 4, pH 6, pH 8, pH 10, and pH 12), which were labeled as PSPI 2, PSPI 4, PSPI 6, PSPI 8, PSPI 10, and PSPI 12, respectively. Compared to that of control PSPI (45.6 %), only the solubility of PSPI 8 (55.5 %) showed increased (p<0.05) value, while the solubility of PSPI 2 (13.7 %), PSPI 4 (10.8 %), PSPI 10 (41.8 %), and PSPI 12 (13.4 %) showed decreased (p<0.05) value. Then the average particle size, zeta potential of the soluble protein in PSPI were analyzed, and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was performed. PSPI 2, PSPI 4, and PSPI 12 showed decreased (p<0.05) average particle size after the pH-shifting process. And PSPI 2, and PSPI 12 showed decreased (p<0.05) zeta potential. While other samples didn’t show any significant difference in these two indicators. Besides, the molecular weight of the increased abundance of soluble protein bands was observed at 33 kDa and 25 kDa of PSPI 8. As the solubility of PSPI 8 increased (p<0.05) significantly, it might suggest the PSPI after pH-shifting treatment under pH 8 has more advantages to be used in the food industry

The paper is devoted to solving the problem of the nutritional and biological value of rye-wheat bread by enriching it with non-traditional local plants raw materials – linseed flour and rice husk fiber. Rice husks are rarely used in bakery production, and in most cases remain unprocessed. However, this research defined the right ways for using them and set as a preliminary work in this field. The study has been carried out in two stages: firstly, linseed flour was added to the rye-wheat bread recipe in an amount of 5; 10; 15; 20 % to the weight of wheat flour. Secondly, dietary fiber was added to these experimental samples, prepared from rice husks without removing amorphous silicon dioxide in an amount of 0.3; 0.5; 0.7 % to the total mass of rye-wheat flour. The optimization of the ratios of the flour components with a simplex-lattice design was carried out and the rheological measurements of dough and bread were conducted on the farinograph and Chopin alveograph.
The study results experimentally found that mixtures of rye-wheat flour and linseed flour with the addition of fiber as “medium in strength” give bread with sufficient volume. The recipe optimization parameters indicated that rational percentage of fiber and linseed flour up to 0.5 % and 15 %, respectively allows increasing the nutritional and biological value of finished products, improves the crumb structure, gas-holding and water-holding capacity of bread, which in turn prevents the stale process and thereby increases the shelf life of finished products.
The obtained results allow us to suggest that, this recipe optimization model could be used in further research, as studies in this direction are limited
