Published: December 2021

El presente trabajo se realizó en el sector San Vicente, Municipio Maturín Estado Monagas, Venezuela entre los meses de junio-septiembre del 2015, con el objetivo de determinar el efecto de cuatro láminas de riego sobre el rendimiento, producción, la calidad de los frutos y eficiencia en el uso del agua en el cultivar Shiraz de calabacín (Cucurbita pepo L.). Se utilizó un diseño experimental de bloques al azar con tres repeticiones, con arreglo de parcelas divididas, donde la parcela principal fueron las diferentes láminas de riego. La parcela principal tuvo dimensiones de 10 m de largo por 3 m de ancho, en la misma se instalaron 4 líneas regantes separadas a 1 m. Se aplicaron cuatro criterios de riego consistentes en reponer el equivalente al 60%, 80%, 100% y 120% de la evapotranspiración del cultivo (ETc). Los parámetros medidos fueron los componentes productivos y rendimiento planta (t/ha). Un tanque evaporímetro tipo “A” se utilizó para estimar la evapotranspiración del calabacín. El tratamiento 120% ETc permitió el máximo rendimiento y calidad (en términos de frutos/planta, longitud, diámetro y peso de la fruta), y la mayor EUA. El máximo rendimiento obtenido fue de 33,39 t/ha. Todas las funciones de producción del rendimiento y de los parámetros de calidad del fruto obedecen a una ecuación matemática del tipo lineal con un alto valor de coeficiente de determinación R2 por encima del 90%. El factor de respuesta del rendimiento del cultivo de calabacín (2,35); mayor de 1 indica que este cultivo es muy susceptible al déficit de agua.

Published: December 2021

Abstract:
Lipid metabolism disorder is a multifactor issue, which contributes to several serious health consequences, such as obesity, hyperlipidemia, atherosclerosis diabetes, non-alcoholic fatty liver, etc. Tannins, applied as naturally derived plants, are commonly used in the study of lipid metabolism disease with excellent safety and effectiveness while producing less toxic and side effects. Meanwhile, recognition of the significance of dietary tannins in lipid metabolism disease prevention has increased. As suggested by existing evidence, dietary tannins can reduce lipid accumulation, block adipocyte differentiation, enhance antioxidant capacity, increase the content of short-chain fatty acids, and lower blood lipid levels, thus alleviating lipid metabolism disorder. This study is purposed to sum up and analyze plenty of documents on tannins, so as to provide the information required to assess the lipid metabolism of tannins.

Authors: Kılınç Namık , Açar Mikail , Tuncay Salih , Karasakal Ömer Faruk 
Published: December 2021

Background:
The 2019 novel coronavirus disease (COVID-19) has caused a global health
catastrophe by affecting the human population around the globe. Unfortunately, there is no specific medication
or treatment currently available for COVID-19.

Objective:
It is extremely important to find effective drug treatment in order to put an end to this pandemic
period and return to normal daily life. In this context and considering the urgency, rather than focusing
on the discovery of novel compounds, it is critical to explore the effects of existing herbal agents with
proven antiviral properties on the virus.

Method:
Molecular docking studies were carried out employing three different methods, Glide extra
precision (XP) docking, induced fit docking (IFD), and molecular mechanics/generalized born surface
area (MM/GBSA), to determine the potential antiviral and antibacterial effects of 58 phytochemicals present
in Rosmarinus officinalis, Thymbra spicata, Satureja thymbra, and Stachys lavandulifolia plants
against the main protease (Mpro) and angiotensin-converting enzyme 2 (ACE2) enzymes.

Results:
7 compounds stood out among all the molecules, showing very high binding affinities. According
to our findings, the substances chlorogenic acid, rosmarinic acid, and rosmanol exhibited extremely
significant binding affinities for both Mpro and ACE2 enzymes. Furthermore, carnosic acid and alphacadinol
showed potent anti-Mpro activity, whereas caffeic acid and carvacrol exhibited promising anti-
ACE2 activity.

Conclusion:
Chlorogenic acid, rosmarinic acid, rosmanol, carnosic acid, alpha-cadinol, caffeic acid, and
carvacrol compounds have been shown to be powerful anti-SARS-CoV-2 agents in docking simulations
against Mpro and ACE2 enzymes, as well as ADME investigations.

Diseases
Authors: Hammad Marwa , Bakry Huny 
Published: December 2021

Background:
Autoimmune inflammatory rheumatic diseases have long been treated by
conventional disease-modifying anti-rheumatic drugs. Biological therapy is a new era in the treatment
of rheumatic diseases, but satisfaction and adherence to it is still not well tested.

Aim:
To assess the satisfaction and adherence to biological treatment among patients with autoimmune
inflammatory rheumatic diseases.

Methods:
A cross sectional study was conducted among 56 patients suffering from inflammatory
rheumatic diseases using Morisky 8 questionnaire and Treatment Satisfaction Questionnaire for
Medication (TSQM) over a period of one month.

Results:
About 76.8 % of the patients had medium adherence and the underlying cause of missing
doses was the unavailability of the drugs. The mean satisfaction with biological treatment was
62.7±6.9. Patients who did not receive formal education had significantly higher satisfaction with
the biological treatment than others 64.94±5.01 at a P value 0.04 (<0.05).

Conclusion:
Patients with inflammatory rheumatic diseases in our study showed medium adherence
and satisfaction. Authorities in the medical field are providing great help to these patients in
need of biological therapy, but ensuring the availability of all doses of the biological treatment regimen
is still necessary. Patient, family and nurse education programs are also necessary to maximize
adherence and satisfaction.

Authors: Bouarroudj-Hamici Khalida , Mettouchi Soraya , Medjkouh-Rezzak Lynda , Larbat Romain , Tamendjari Abderezak 
Published: December 2021

Background:
The olive tree (Olea europaea L.), the most widespread plant species in
the Mediterranean basin, includes two forms: cultivated (var Europaea) and wild (var Sylvestris).
Wild olive trees or oleasters cover large areas in Algeria. It has been shown that oil from oleaster
has a higher content of phenolic compounds, which could have antimicrobial properties.

Objective::
The objective of this study was to assess the antibacterial activity of phenolic extracts
from four Algerian oleaster oils and an extra virgin olive oil (EVOO) from Chemlal variety.

Methods:
Phenolic compounds were determined by UHPLC-MS. Antibacterial activity was tested
against six referenced human enteropathogenic bacteria by the agar disc diffusion method by measuring
the diameters of the zone of inhibition.

Results:
The results revealed a similarity between the phenolic composition of oleasters 1 and 3
and between oleaster 4 and EVOO; however, the phenolic composition of oleaster 2 that the poorer
was markedly different with a higher content of free phenolic alcohols and lower in secoiridoids.
Almost all bacteria showed to be sensitive against the antibiotics, with the value of ZOI ranging
from 5-32 mm; otherwise, most of the oleaster extracts exhibited higher antibacterial activity than
the EVOO with ZOI values of 7-12mm. A significant correlation was noted between phenolic content
and antibacterial activity.

Conclusion:
These results show that oleaster oil can be considered a high potential food.

Authors: Hofmann Tamás , Albert Levente , Bocz Balázs , Bocz Dániel , Visi-Rajczi Eszter 
Published: December 2021

Background:
Coniferous cones are a by-product of forestry and wood logging, used for
many possible purposes, e.g., the extraction of polyphenols. Objective: The aim of the present article
was the comparison of the antioxidant polyphenol content of the differently matured cones of
17 selected conifers, either common in Hungary or yet uninvestigated.

Methods:
Total polyphenol content, ferric reducing antioxidant power and 2,2-diphenyl-1-picrylhydrazyl
assays were used to determine the antioxidant contents. A scoring system was implemented
using the three assay results to evaluate and compare the overall antioxidant power of the samples.

Result and Conclusion:
Highest antioxidant contents were found in green cones, followed by mature
and opened cones. Taxa with the highest scores were Tsuga canadensis, Cryptomeria japonica,
Chamaecyparis lawsoniana, Thuja orientalis, Metasequoia glyptostroboides and Picea abies. For
the samples with the highest overall antioxidant power the high-performance liquid chromatographic/
tandem mass spectrometric polyphenol profiling was carried out (green cones of T. canadensis
and P. abies) and 83 compounds have been tentatively identified and described. Results contribute
to the future bioactivity testing and evaluation of the cone extracts of T. canadensis and P. abies.

Authors: Kadi Ahcene , Boudries Hafid , Bachir-bey Mostapha , Teffane Mohand , Taibi Abdeslem , Boulekbache-Makhlouf Lila 
Published: December 2021

Background:Citrus fruits, especially clementines, are among the most consumed fruits in the world. Clementine consists of pulp (endocarp) and peel (epicarp) which are rich in carotenoids. After using fruit pulp, peels are usually discarded as waste; the valorization of the latter in the recovery of its beneficial components, mainly carotenoids, may seem to be important.Objective:The main objective of this study is to determine the optimal conditions allowing the extraction of a high carotenoids yield from clementine peels.Methods:The microwave-assisted extraction method (MAE) was applied for extraction of total carotenoids from Citrus clementina peels, and the response surface methodology (RSM) was used to investigate the influence of extraction parameters, including hexane concentration, microwave power, irradiation time, and solvent to solid ratio, on the extraction yield, then the results were modeled using a second order regression. Total carotenoids yield of clementine peel extract obtained under optimal microwave-assisted extraction conditions was compared to extracts performed using two conventional extraction methods (maceration and Soxhlet).Results:The optimal conditions for microwave-assisted extraction were 68 % of hexane concentration using 561 W of microwave power during 7.64 min of irradiation time, 43 ml/g of solvent-tosolid ratio using two successive extractions. Under optimized conditions of microwave-assisted extraction, the recovery of carotenoid content was 186.55 μg/g dry matter (DM), which was higher than that obtained by the two conventional methods, maceration extraction (ME; 160.53 μg/g DM) and Soxhlet extraction (SE; 162.68 μg/g DM).Conclusion:From this study, it can be concluded that microwave-assisted extraction is an efficient method for carotenoid recovery and considering its high yield in reduced time, it could be recommended for extraction of these bioactive compounds from clementine peels.
Natural Organic Matter (NOM) Transformations and their Effects on Water Treatment Process: A Contemporary Review
Authors: Karnena Manoj Kumar , Konni Madhavi , Dwarapureddi Bhavya Kavitha , Saritha Vara 
Published: December 2021

Abstract:
One of the several significant concerns related to water treatment plants is the transformation of natural organic matter (NOM) concerning quality and quantity due to the changing climatic conditions. The NOM consists of heterogeneous functionalized groups. Phenolic and carboxyl groups are the dominant groups that are pH-dependent and show a stronger affinity towards the metals. Properties of natural organic matter and trace elements govern the binding kinetics, influencing cations' binding to functionalized groups at lower pH. The water treatment process mechanisms like adsorption, coagulation, membrane filtration, and ion exchange efficiencies are sturdily influenced by the presence of NOM with cations and by the natural organic matter alone. The complexation among the natural organic matter and coagulants enhances the removal of NOM from the coagulation processes. The current review illustrates detailed interactions between natural organic matter and the potential impacts of cations on NOM in the water and wastewater treatment facilities.
Diffusion and Surface Reaction in Porous Cubical Catalyst: A
Mathematical Approach
Authors: Ghosh Sourav , Pal Dipankar 
Published: December 2021

Background:
Catalysts are the most vital part of any chemical industry. Catalyst
is a substance that affects the rate of reaction, but the catalyst itself does not take part
in the reaction. Catalysts offer different pathways of reaction by diffusing the reactant
inside it to provide a large surface area within a small volume, thus, lowering the activation
energy of molecules for reaction. Most of the catalytic reactions take place in a liquid-
solid or gas-solid interface where catalysts are mostly porous in nature. Spherical and
cubic-shaped catalyst particles are commonly used in different industries.

Methods:
In the first phase of the present study, the physics behind the diffusion inside
the catalyst pellet has been discussed. In the second part, governing differential equations
have been established at a steady-state condition. For solving the differential equation,
the equation is made dimensionless. Physical boundary conditions were used to solve the
diffusion equation. The assumption of writing the differential equation of the reaction is
elementary. Then, the Thiele modulus is derived in terms of the reaction and geometrical
parameter (Length).

Results and Conclusion:
In the third part, the differential equation is solved for firstorder
reaction with some constant values of the Thiele modulus, and three-dimensional
plots are obtained using numerical analysis. After that, the obtained Thiele modulus and
effectiveness factor plot are compared to draw the conclusion of rate limiting reaction
and internal diffusion.
New Efficient Configurations for Sour Wastewater Treatment
Authors: Gadalla Mamdouh A. , Ghallab Ayat , Mansour Ahmed M. , Ashour Fatma H. , Elazab Hany A. 
Published: December 2021

Background:
The environmental legislation on pollutant concentrations in
aqueous effluents tends to tighten and increase due to the huge efforts devoted as a response
to global warming and its related negative impact on our planet. As a result, sour
water must be handled and processed properly to provide a high quality of stripped water
with insignificant traces of NH3 and H2S. This approach must be achieved within the
minimum operating costs. This scientific research investigates the stripping configurations
of sour water effluents from various industries. The research also offers an insight
into different scenarios and configurations to accomplish set targets satisfying the environmental
law criteria.

Methods:
This research introduces a range of heat integration schemes for saving energy.
Further, vapor recompression “VRC” technique is opted for its ability to maximize energy
savings. This research also investigates the effect of operating and design variables on
the stripped water quality, such as feed temperature, feed location, reflux split, and steam
flow rate. The option of adding new equipment is also addressed to maximize heat integration
and enhance the efficiency of the process. Thus, several schemes and process
configurations are explored to treat the industrial sour water waste streams seeking better
efficiency. Those configurations differ from one another in heat integration layout and
VRC utilization. The energy efficiency and economics of the proposed configurations are
considered decisive factors in this research study. The case study adopted in this research
is based on published data taken from several iron and steel factories in South Korea
named POSCO (Pohang Iron and Steel Corporation).

Results:
The obtained results of the treated wastewater streams guarantee that the effluent
sour water obeys the standard environmental regulations, i.e., NH3 contents range
from 30 to 80 ppm and H2S concentration falls below 0.1 ppm. The obtained results of
the seven different scenarios are compared to the original case study. It is found that scenario
7 is the most economical solution saving 51.54 % of the total annual cost compared
to the original case study while satisfying the treated water environmental regulations
with a concentration of 3.19 ppm NH3 and 0.05 ppm H2S. Scenario 7 creates its own
steam, unlike the original case study where steam utility is needed extensively. However,
scenario 7 consumes 15 % more electricity than the original case study, but it also still
shows 56.34 % less than the overall utility cost.

Conclusion:
The optimum process configuration can be employed for other sour water purification
systems such as those used in petroleum refiners. An ongoing research work focuses
on the use of internal heat integration for more energy savings and economic improvement.
