Assessment of phytotoxicity of treated water of Tabuk wastewater plant by different technologies on seed germination of chick pea (Cicer arietinum)
Authors: Siddiqui Zahid Hameed , Abbas Zahid Khorshid 
Published: July 2021

Abstract
The use of reclaimed water as an alternative source is a sustainable way forward for an arid country like The Kingdom of Saudi Arabia. The sewage contains organic and inorganic pollutants from households and industrial sources that may not be removed during treatment. In this study, seeds of Cicer arietinum were germinated using six different concentrations of treated water from the Tabuk wastewater treatment plant and tap water was used as control. The physicochemical properties such as total dissolved solids, electrical conductivity, total suspended solids, and turbidity values of treated water were higher, which gradually decreased on dilution with tap water. The amount of ammonia, nitrite, nitrate, and phosphate was in higher concentration in treated water as compared to control. The use of 40% treated water (T3) improved the germination percentage, speed of germination and germination index of C. arietinum. The phytotoxicity test reveals that undiluted treated water (T6) is not fit for direct use on plants. All the investigated treatments confirmed that the use of more than 40% of treated water decreased the fresh weight and dry weight of the seedlings as compared to control. The results are encouraging and help in attaining water sustainability in the Tabuk region.
Production of Highly Thermostable Laccase from Penicillium spinulosum
for Enhanced Delignification of Untreated Wheat Bran
Authors: Olajuyigbe Folasade M. , Oduwole Ademola K. , Fatokun Cornelius O. 
Published: July 2021

Background:
Lignin confers rigidity on plant cell wall and poses a challenge to the hydrolysis
of cellulose, which makes the production of biofuels from lignocellulose an overwhelming
problem. This prompts a continuous search for novel ligninolytic enzymes, especially laccases for
delignification of lignocellulose for improved saccharification of biomass.

Objective:
This study reports the production, physicochemical properties, and delignification efficiency
of laccases from Penicillium and Trichoderma species on untreated wheat bran.

Methods:
Fungal laccases were produced using different agro residues (wheat bran, coconut shell,
and palm kernel shell) as substrates in submerged fermentation. The best substrate for laccase production
was determined. Physicochemical properties of crude enzymes and delignification efficiency
of the laccases were determined on untreated wheat bran using pure laccase as control.

Results:
Wheat bran supported maximum laccase production from fungi under study. The highest
laccase yield of 22.5 U/mL was obtained from P. spinulosum. Laccase from P. spinulosum was optimally
active at pH 7.0 and 50°C and exhibited remarkable high thermostability with 61.6% residual
activity at 90°C after 2 h incubation. The activity of the thermostable enzyme was enhanced in
the presence of Cu2+. Biodelignification efficiency of cell-free extract from P. spinulosum, T. koningii,
and P. restrictum on wheat bran was 95%, 81.5%, and 63.5%, respectively. Surprisingly, a
much lower delignification efficiency of 33.42% was obtained with commercial laccase from Trametes
versicolor.

Conclusion:
The high thermostability and striking delignification efficiency of crude laccase from
P. spinulosum make the enzyme a good bioresource for biodelignification of untreated lignocellulose
for biofuel production.

Published: July 2021

Background:
Diabetes mellitus is a complex chronic metabolic disease with heterogeneous
etiology and risk factors at the social level and behavioral, environmental, and genetic susceptibility.
There are numerous traditional medicinal plants reported having hypoglycemic properties,
such as Allium sativum (Garlic), Azadirachta indica (Neem), Punica granatum (Anar), Trigonella
foenum (Fenugreek), Momordica charantia (Bitter gourd), and Ocimum sanctum (Tulsi).
The use and delivery of herbal medicine as a dosage form in treating and preventing diseases has a
long history started with use in Mesopotamia in 2600 B.C. However, the oldest record on the practice
of medicinal plants for drug preparation was engraved on a Sumerian clay slab, created over
5,000 years ago. The use of medicinal plants is continuing in this modern era, and it has been estimated
that approximately one-fourth of prescription medicines worldwide are derived from plants.

Objective:
The present study was carried out to evaluate the anti-diabetic effects of Ethanolic extract
of leaves of Punica granatum, Beta vulgaris, and Azadirachta Indica in alloxan-induced diabetic
rats. The use of herbal products is not only limited to dietary uses, such as food, nutrition,
etc., but it also has a distinct role in the remedy of several diseases.

Methods:
Animals were induced with diabetes using Alloxan and then were observed on the basis
of numerous parameters to access the induction and control of diabetes in comparison to all groups.
The animal received dosing of Herbal extracts in treated groups and was checked for Fasting blood
glucose. Neurobehavioral studies and the weight of all animals were checked on 7, 14, 21, 28 days
after induction of diabetes.

Results:
The results proved that the herbal extract of the powder was anti-diabetic in action.

Conclusion:
The herbal extract must be tested for the phytoconstituents, and the active constituent
must be isolated to perform research on humans.

Authors: Chi Chien-Yu , Ao Shuang , Winkler Adrian , Fu Kuan-Chun , Xu Jie , Ho Yi-Lwun , Huang Chien-Hua , Soltani Rohollah 
Published: July 2021

Background
In-hospital cardiac arrest (IHCA) is associated with high mortality and health care costs in the recovery phase. Predicting adverse outcome events, including readmission, improves the chance for appropriate interventions and reduces health care costs. However, studies related to the early prediction of adverse events of IHCA survivors are rare. Therefore, we used a deep learning model for prediction in this study.

Objective
This study aimed to demonstrate that with the proper data set and learning strategies, we can predict the 30-day mortality and readmission of IHCA survivors based on their historical claims.

Methods
National Health Insurance Research Database claims data, including 168,693 patients who had experienced IHCA at least once and 1,569,478 clinical records, were obtained to generate a data set for outcome prediction. We predicted the 30-day mortality/readmission after each current record (ALL-mortality/ALL-readmission) and 30-day mortality/readmission after IHCA (cardiac arrest [CA]-mortality/CA-readmission). We developed a hierarchical vectorizer (HVec) deep learning model to extract patients’ information and predict mortality and readmission. To embed the textual medical concepts of the clinical records into our deep learning model, we used Text2Node to compute the distributed representations of all medical concept codes as a 128-dimensional vector. Along with the patient’s demographic information, our novel HVec model generated embedding vectors to hierarchically describe the health status at the record-level and patient-level. Multitask learning involving two main tasks and auxiliary tasks was proposed. As CA-mortality and CA-readmission were rare, person upsampling of patients with CA and weighting of CA records were used to improve prediction performance.

Results
With the multitask learning setting in the model learning process, we achieved an area under the receiver operating characteristic of 0.752 for CA-mortality, 0.711 for ALL-mortality, 0.852 for CA-readmission, and 0.889 for ALL-readmission. The area under the receiver operating characteristic was improved to 0.808 for CA-mortality and 0.862 for CA-readmission after solving the extremely imbalanced issue for CA-mortality/CA-readmission by upsampling and weighting.

Conclusions
This study demonstrated the potential of predicting future outcomes for IHCA survivors by machine learning. The results showed that our proposed approach could effectively alleviate data imbalance problems and train a better model for outcome prediction.

Authors: Saiyan Sergey G. , Paushkin Alexander G. 
Published: July 2021

Introduction. The numerical parametric study of the stress-strain state of I-beams, having versatile corrugated walls, was carried out in the ANSYS Mechanical APDL software package. Numerical results are obtained for displacements, equivalent stresses and stability coefficients depending on the change in the inclination angle of web corrugations for trapezoidal, wavy and triangular profiles. The obtained results can help to design and substantiate the design solutions applicable to bending elements.
Materials and methods. The parametric study involved a series of numerical experiments conducted using the finite element method in the ANSYS Mechanical APDL software package. APDL parametric language was used to develop the software that was built into the software package. It allowed to perform a parametric reconstruction of the numerical model depending on varied parameters of the corrugated wall, and the reconstruction was followed by the numerical solution and post-processing of the calculation results. The calculations were made with the help of the model whose overall dimensions and material were identical to those of a standard I-beam having a solid wall exposed to a uniformly distributed transverse load.
Results. The parametric study enabled the co-authors to identify the main features of the stress-strain state of the beams that had different types of corrugated walls. A parametric numerical model was compiled to determine maximum displacements, equivalent stresses and stability coefficients for various types of corrugated walls and various parameters of the corrugation angle. Isofields of equivalent stresses and buckling modes are provided for characteristic parameters and types of corrugations. The reliability of the obtained results was confirmed by the verification of the numerical model using the method of the strength of materials and corrugation inclination angle α = 0, which was the initial point of simulation for all types of corrugations.
Conclusions. The results, obtained in the course of parametric studies, have identified the main features of the stress-strain state of beams having corrugated walls; they allow to substantiate their effectiveness as design solutions applied to bending elements.

Published: July 2021

Introduction. The adjustability of electrical properties of materials, that have hydraulic setting characteristics, has been studied over the last decades. It is emphasized that any change in electrical properties, triggered by various additives, causes negative side effects, including low corrosive resistance and modified physical and mechanical characteristics. The purpose of this research is to design a multifunctional layered material that features localized electrical conductivity. The objective is to track the influence of modifiers, capable of regulating electrical properties.
Materials and methods. Samples were made of Portland cement I 42.5; the cement, having the fineness modulus of 0.7, was used as the aggregate; samples also contained ground Sulphur type 9998 (GOST 127.1-93), soot slurry, and calcium nitrate. The co-authors have identified the unit resistance values of each layer of this composite material, mechanical properties and features of each layer, and the structure of contact layers.
Results. The co-authors have determined that the addition of pre-treated Sulphur in the amount of 7 % of the binder mass facilitates the formation of a nonconductive layer, whose unit resistance reaches 29.57 kiloohm cm on the 28th day. The conductive layer, generated by adding soot in the amount of 7 % of the binder mass, ensures the stable passage of electric current. The co-authors have identified that calcium nitrate influences the morphology of secondary crystalline hydrates and the non-crystalline phase of the mineral matrix, made of Portland cement, and it also ensures the required concrete strength.
Conclusions. The layered method of formation of new compositions allows to make composite materials having adjustable electrical characteristics. New materials are made of Portland cement, and they contain no non-conductors. The co-authors have proven the efficiency of Sulphur, an integrated modifier made of soot and calcium nitrite, used as the modifiers of the mineral matrix, since they regulate the electrical properties of the artificial stone.
