Published: June 2022

Ciplukan (Physalis angulata L.) is one of the plants from the class of herbal plants that is good to be developed because people are starting to choose herbal treatment. The content of ciplukan fruit is phenolic and flavonoid. Thus, technology for enlargement and increasing fruit content with the giberellin (GA3) hormone is needed. GA3 functions to stimulate the formation, development of fruit and increase the biosynthesis of secondary metabolites. This study aimed to determine the influence of the GA3 hormone on the phenolic content and antioxidant activity in ciplukan fruit. The experimental design used RAL 5 treatments: GA3 concentrations of 0 ppm (P0), 15 ppm (P1), 20 ppm (P2), 25 ppm (P3), and 30 ppm (P4). The parameters studied were the number of fruit, fruit size, fresh weight of fruit, total phenolic, total flavonoid, and antioxidant activity (DPPH method) in ciplukan fruit. The results showed that the concentration of 30 ppm (P4) of GA3 was showed the highest values on the number of fruits (33±3.53 g), fruit length (14.23±0.35 mm), width (12.87±0.39 mm), and fresh fruit weight (38.6±3.97 g) without calyx. The concentration of 30 ppm (P4) also affected the phenolic content (2.52±0.23 mgGAE/g), flavonoids (2.43±0.18 mgQE/g), and IC50 value of antioxidant activity (60.59 g/mL).

Published: June 2022

Abstract
This study aims to model a new type of open-ended pipe pile embedded in sand soil by a 3D finite element modeling using Midas GTS NX software. The new pipe model comprises the addition of an external ring and reverses wings. The soft computing simulation includes comparing the bearing capacity of the ring and wings-pipe piles with the conventional hollow piles, all piles have 40 mm diameter (D) and length (L) 800 mm and have been tested in loose dry sand. These piles have been tested experimentally using a physical model specially designed and manufactured for this purpose. The soft computing for modeling the new pipe pile has been validated using the obtained experimental results. The experimental results show that the proposed new model of the pipe pile has a higher-bearing capacity of (274%) than the open-ended pipe pile, and (148%) than the closed-end pipe pile. Also, this study has explained the adopted procedures of the finite element modeling of the ring-wing- open-ended pipe pile and includes the finite element modeling of the constrained soil inside the pipe pile and the external ring and inside the external reverse wings. The simulation results show that the soft computing using Midas GTS NX gives a good conceptualizing regarding the formation of the two types of the soil arching phenomena (passive and active) arching of the constrained soil inside pipe pile which could not be studied experimentally. Moreover, it gives good convergence of the load settlement behavior when verified with the experimental results.
Fine Unwrapping Phase for Deformation Control
Authors: omar Hadj Sahraoui 
Published: June 2022

Abstract
Earth observation and environmental control are becoming more important where the realization of DEM by the technique of interferometry of RSO images facilitates the control of terrestrial deformations, which is the subject of this paper. The unwrapping phase is a very important step in the interferometry process, especially to treat it carefully in steep degraded and mountainous ground. We have focused on the reduction and sometimes the elimination of the residues in flat terrains and otherwise to keep the maximum of the residues in the very steep sites. For this purpose, the methods developed and proposed are based on a transformation by the ISODATA which is based on KMEANS and the double passage of the median filter, and this in order to limit the creation of the brunch-Cut for the progress of the filtered interferogram (elimination of large black spot on The Brunch-Cut image).The tests of this method were carried out on several sites, and showed good results.

Abstract
Objective In patients with ankylosing spondylitis (AS) who develops sudden and severe low back pain, serious causes such as infections, spinal instability, and vertebral fractures should be evaluated in the differential diagnosis.Methods A 34-year-old male patient with AS, who was previously followed in remission, presented with severe low back pain and limping. He had bilateral sacroiliitis on magnetic resonance imaging (MRI) taken at another center recently on his admission. Visual analog scale score was 10 and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score was 9,6. In laboratory evaluation, C-reactive protein (CRP) level was 13 mg/dl and leukocyte count was 17,000/uL. After blood and urine cultures, tuberculosis and brucella tests were taken, prophylactic antibiotic treatment was given. In MRI, a multiloculated abscess formation which starts from the left S1 level and extends along the posterior of the iliopsoas muscle and presses on the bladder and prostate was observed. Percutaneous abscess drainage was performed under the guidance of computed tomography (CT). Results There was a rapid improvement in pain scores and acute phase reactants following abscess drainage. After 2 weeks, a significant regression of abscess formation was seen in the control CT evaluation.Conclusion Red flags should be checked in patients with AS who have severe low back pain unresponsive to routine treatment and other causes of low back pain should not be ignored.
Oxidative degradation of Metolcarb by electro Fenton process
Authors: Bakhti Hayet , Hamida Najib Ben , Hauchard Didier 
Published: June 2022

Abstract
This study presents the degradation and the mineralization of Metolcarb or 3-methylphenyl methylcarbamate by electro Fenton process with volume cathode. This pesticide was treated using this cathode which is filled with graphite carbon granules. The solutions of Metolcarb were electrolyzed in an reactor of 1.4 liter which shows the performance and the efficiency of the process. Indeed, the effects of different parameters such as the initial concentration of Metolcarb and the intensity of applied current on the degradation kinetics of Metolcarb have been discussed as a function of time. The found results proved that the insecticide removal followed a pseudo first order. The competitive kinetics analysis of Metolcarb during its electrochemical treatment was carried out by using benzoic acid as a reference compound. The absolute rate constant for the oxidation of Metolcarb by hydroxyl radicals consequently is equal to 3.59 × 109 L mol− 1 s− 1. The mineralization of Metolcarb in terms of total organic carbon was monitored during its electrolysis by the electro Fenton process. The organic carbon is then equivalent to the total carbon determined in reaction analysis. Carbon chains can therefore be formed. The various intermediates which are produced into the electrochemical processing of Metolcarb were determined by the mass spectrometry LC/MS. The biodegradation of Metolcarb has also been investigated in active clay.

Abstract
Wire arc additive manufacturing is a type of additive manufacturing process in which layer upon layer is added to form a closely welded component. In this study, gas metal arc welding - pulse and gas metal arc welding - double pulse methods were used to manufacture the components with 5356 aluminum alloy. the microstructures of the pulse and double pulse were observed and compared, the results show that the bead formation, structure, formability and continuity appeared to be better on the double pulse welding when compared to pulse. The pore formations were found in larger numbers in pulse than double pulse, due to the presence of a larger number of pores in pulse, it is weaker than double pulse.
A novel synchronization between two different chaotic systems (Convert Lorenz chaotic system to Chua chaotic system)
Authors: Kafi Dina Ahmed , Mousa Salam K. , Jamal Raied K. 
Published: June 2022

Abstract
In this work, a new synchronization was achieved between two different chaotic systems in behavior (Chua-Lorenz) by coupling them together with a coupling factor (k) and it was noted that Lorenz's behavior completely transformed Chua's behavior by changing the value of this factor. It is observed that when the values of the coupling factor are zero, the two systems are asynchronous, and when its value is 100, there is partial synchronization, while its value is 100000, so we get perfect synchronization. Where it is possible to use this synchronization in the field of secure communications.

Abstract
Background:
Autism spectrum disorders (ASDs) comprise a heterogeneous group of pathological conditions, mainly of genetic origin, characterized by stereotyped behavior, marked impairment in verbal and nonverbal communication, social skills, and cognition. Excitatory/inhibitory (E/I) imbalances have been recorded as an etiological mechanism of ASD. Furthermore, GABA, the main inhibitory neurotransmitter in adult life is known to be much lower in both patients and rodent models of ASD.
Methods:
In the present study, forty young male western Albino rats, 3–4 weeks in age, weighing about 60–70 g were used. The animals were randomly assigned into six experimental groups; each of them included eight rats. Group (I) serves as control orally given phosphate-buffered saline. Groups (II, III) serve as a rodent model of ASD, orally administered a neurotoxic dose of PPA. The rats in the three therapeutic groups (IV, V, and IV) received the same doses of PPA followed by 0.2 g/kg body weight of pure Bifidobacterium infantis, the probiotic mixture of (ProtexinR), and pure Lactobacillus bulgaricus respectively for three weeks. Selected variables related to oxidative stress, glutamate excitotoxicity, and gut bacteria were measured in the six studied groups.
Results:
Both pure or mixed Lactobacillus and Bifidobacterium were effective in ameliorating glutamate excitotoxicity as an autistic feature developed in the PPA-induced rodent model. Their therapeutic effects were mostly through, the correction of oxidative stress, restoring the depleted GABA neurotransmitter, and up-regulating the gene expression of GABA receptors. Pure Bifidobacterium was the most effective followed by the mixture of probiotics, and finally lactobacillus.
Conclusion:
Bifidobacteria and lactobacilli could be used either independently or in combination as psycho-biotics to ameliorate oxidative stress and glutamate excitotoxicity as two confirmed etiological mechanisms through the gut-brain axis.

Authors: Hurtado Ivan , Bonacina Erika , Garcia-Manau Pablo , Serrano Berta , Armengol-Alsina Mireia , Mendoza Manel , Maiz Nerea , Carreras Elena 
Published: June 2022

Abstract
Objective
To create a predictive model including biomarkers and evaluate its ability to predict adverse perinatal outcomes in late-onset small fetuses, ultimately helping to provide individualized counseling at the time of diagnosis.
Methods
This was a prospective observational study, including singleton pregnancies with an estimated fetal weight (EFW) below the 10th percentile, at a gestational age between 32 + 0 and 36 + 6 weeks of gestation (WG). Variables recorded at diagnosis to predict adverse pregnancy outcomes were: soluble fms-like tyrosine-kinase-1 to placental growth factor ratio (sFlt-1/PlGF), fetal Doppler, uterine artery pulsatility index (UtAPI), EFW percentile, gestational age, and the presence of maternal risk factors for placental insufficiency. Logistic regression models were developed for the prediction of adverse perinatal outcomes (APO) or the need for elective delivery before 35 or 37 WG.
Results
Sixty (52.2%) fetal growth restricted (FGR) and fifty-five (47.8%) small for gestational age (SGA) were enrolled. Thirteen (11.3%) women needed elective delivery before 35 WG and 27 (23.5%) women before 37 WG. At least one adverse perinatal outcome (APO) occurred in 43 (37.4%) pregnancies. The best marker in univariable analyses was the sFlt-1/PlGF ratio [AUC = 0.932 (95% CI, 0.864–0.999)]. The multivariable model including sFlt-1/PlGF showed a better predictive performance for APO than the multivariable model without sFlt-1/PlGF (P < 0.024).
Conclusion
sFlt-1/PlGF is a good predictor of APO at the time of late-onset FGR/SGA diagnosis. Our predictive models may be useful to provide early individualized prenatal counseling in this group of women. Further studies are needed to validate these preliminary findings in a larger cohort.

Published: June 2022

Abstract
Background: bariatric surgery is one of the most popular weight-loss methods at present, which can significantly reduce the weight of obese patients and improve the complications. Through 4-week exercise intervention and routine postoperative management control, the changes of subjects' indexes were observed to provide reference for making scientific exercise plan.Methods: 17 subjects were randomly divided into two groups, EG (n=8) and CG (n=9). The exercise group received online exercise intervention for 4 weeks, 3 times a week, while the CG did not participate in exercise. The related indexes of EG and control group before and after exercise intervention were detected and analyzed.Results: The HC of the control group was better than that of the EG (P < 0.05). The improvement of WHR in EG is better than that in CG (P < 0.01). The decrease of TF in EG is better than that in CG (P < 0.05). The decrease of BMR was better than that of the CG (P < 0.05). The effect of lowering FBG in the CG is better than that in the EG (P < 0.01). EG improved HDL-C better than CG (P < 0.01).Conclusion: (1) the CG has a greater effect on reducing WC, and exercise has a more significant effect on reducing WHR and TF and BMR. (2) the CG has a greater effect on reducing FBG, but exercise can adjust the relative stability of FBG level. Exercise can improve HDL-C obviously.
