Abstract
Double immiscible fluids has been drastically emerged in science and technology. In this research, combined convection of double immiscible fluids in a vertical square duct is investigated. One layer is natural fluid whilst the alternative is nanofluid. Both the layers are saturated with porous matrix having different permeability’s. The Tiwar-Das version and Dupuit-Forcchiemer is applied to outline the nanofluid and permeable fluid respectively. Southwell Over Relaxation approach is utilized to find the solutions of conservation equations along with suitable boundary and interface conditions. An interfacial stress andheat flux situations are hired on the intersection among immiscible liquid zones. Essential standards defining the fluid flow and transfer of energy are studied deliberately. Grashof number, Brankman number, Darcy number, inertial parameter, permeability ratio, solid volume fraction fraction, viscosity and thermal conductivity ratios, different nanoparticles, various base liquid of the two layer beverages are engaged. The effects reveal that the Grashof, Brinkman and Darcy numbers increase the momentum while inertial, solid volume fraction, viscosity and thermal conductivity ratios depletes the momentum. The temperature distributions aren't a lot modulated with any of the controlling parameters. By sagging nanoparticles the velocity is not much reformed however reckoning copper nanoparticle and applying ethylene glycol – mineral oil as base fluids regulates the best flow. Diamond nanoparticle dropped in water catalyses the best heat transfer rate.

Abstract
Biogas is usually available as a fuel in the gas engine or micro gas turbine to generate the power by energy conversion. Since biogas contains CO2 of approximately 40 vol%, the heating value is low compared to natural gas, resulting in a decrease in the efficiency of power generation. Therefore, this study adopts the biogas dry reforming process to produce H2, which can be used as s fuel for solid oxide fuel cell (SOFC). CO which is by-product from biogas dry reforming can be used as a fuel for SOFC. This study adopts the Ni as catalyst since Ni-based catalyst is the most common catalyst for biogas dry reforming process. This study also pays attention to a membrane reactor to improve the performance of biogas dry reforming. Since the biogas dry reforming is an endothermic reaction, it is expected that the performance of producing H2 is improved especially at lower temperature. Some studies investigated the membrane reactor for CH4 dry reforming. However, it can be said that the impact of operation condition such as pressure difference between reactor and sweep chamber, molar ratio of supplied gas and reaction temperature on the performance of biogas dry reforming has not been investigated well. Therefore, the purpose of this study is to optimize the operation condition such as pressure of sweep chamber, molar ratio of supplied gas and reaction temperature on the performance of biogas dry reforming. In the presentation, Dr. Akira Nishimura talks abuot the results and discussion of this study.

Abstract
Theoretical studies of free convection nanofluid flow between two parallel plates with mass diffusion are conducted. Copper nanoparticles are considered using water as a base fluid. One of the plates is oscillating. Thermal radiation, chemical equation, and magnetic effects on the fluid are investigated. The problem's governing equations are transformed into dimensionless equations and solved using the Laplace transform method. Analytical expressions for concentration, velocity, and temperature profiles are obtained. These solutions satisfy the governing equations as well as the initial and boundary conditions. All profiles, as well as the Sherwood number, Nusselt number, and skin friction influenced by important physical parameters, are graphically depicted. The effects of nanoparticles and oscillation are also studied and discussed.

Abstract
The increasing world energy demand coupled with declining conventional oil production prompts toward an increased emphasis on tight oil. Water flooding is one of the important methods to improve tight oil recovery. Flow characters and the effect of surfactants in injection pressure and oil recovery were investigated. Flow during water flooding can be roughly divided into four stages according to the injection pressure and flow change. The injection pressure experienced stages of increasing to peak, then decreasing and finally becoming stable, accompanied by the increasing of oil production until water break through. Oil phase permeability decreases faster in samples with lower permeability. The contribution of oil recovery mainly happened at the early stage. The effect of interfacial tension reduction and wettability alteration by surfactant and its implication for oil recovery in tight oil reservoirs was analyzed. Gemini surfactant was more beneficial to reduce interfacial tension while Fluoride could make the wettability changed from original hydrophilic and oil-hydrophilic to neutral wetting (hydrophobic and oil-phobic). The average reduction rate of injection pressure by fluoride and Gemini surfactant was 32.4% and 14.2%, respectively. The improvement of recovery mainly occurred in primary water flooding, while the amount of oil displaced by surfactant solution and secondary water flooding was little or even no oil displacement. Changing rock wettability is more favorable than reducing the interfacial tension for oil recovery in tight sandstone oil reservoirs.

Abstract
We present a general model for scientific theory. A general model handling not only one or two “forces” such as gravitation and electromagnetism can actually be constructed with a high functionality.
It is in this situation very important that Albert Einstein’s Theory of relativity for gravitation is included in the model. For example models for the strong force have been constructed on the
Theory of relativity. The theory of Relativity is based on the fact that controlled potentials is
Build up using the mathematical notion of curvature. However we can do better by mathematically rewrite these curvature potential function into trigonometric waves,sinesan cosines therefore constructing a wave theory of more than two forces. Quantum physics with electromagnetism allows mathematical functions analogue to Kepler Third Law this is equal to a sinusoidal relation found in Theory of relativity and therefore works also for the strong force. By using a what we called a “proper mass”, term from special relativity together with the General Relativity Schwartschild term

Abstract
An any form of research that begins and ends with appropriate statistical techniques is regarded as falling within the umbrella of the fundamental science of statistics. On how we may embrace and use statistical approaches in the research and publication processes, the insight of statistical knowledge has been briefly examined from a number of viewpoints. Many scientists and researchers do not adhere to statistical ethics when conducting research, which undoubtedly has an impact on compilation and interpretation. The current work fills the aforementioned research gap by addressing statistical ethics and other research postulates. In addition to that, the academic journals have become more digital; writers now have more chances to increase the visibility of their research and its citations globally. The metrics is the gold standard. It is used to decide the ranking and benchmark of the journals which will be determined using bibolometrics and different algorithms. Numerous predatory journals lack of international standards and low quality. Authors will be unable to submit their research papers or reports to the journals for publication with a high impact factor in this circumstance. The main objective of this study is to focus on identifying the global citations by investigating the author level metrics of the top hundred scholarly publications. Data were gathered from Google Scholar source between January 2021 and September 2022 for the study, which was quantitative in nature. Hypothesis was tested by simulation growth model and statistically approximates the h5 citation and Journal impact factor. Asper the results, top hundred ranking was seen in Nature Reviews and Molecular Cell Biology (h5 155, IF 113.90 h5 median 340) followed by nature reviews immunology (h5 152, IF 108.60 h5 median 292), The highest ranking discipline that was substantially correlated with citation was health and medical sciences (r = 0.91, R2 % = 0.97) followed by physics and mathematics (r = 0.89, R2 % = 0.94). Finally, this study implies that open access will facilitate readers access to journal material as well as serve as a tool for publishers, scientists and researchers enabling them to make informed decisions at the appropriate moment and disseminate scientific knowledge. The global platform of researchers can benefit from the insight understanding that statistical ethics can offer.

Abstract
The Forensic world has been using fingerprints as the standard for identifying people for more than a century.Even after the discovery of DNA Profiling, science of fingerprint is still considered as one of the best method for personal identification. The science of fingerprint recognition has advanced throughthe initial usage of finger-prints enormously and todaythe use of biometric data in national and international legal proceedings have surpassed other conventional methods of Forensic Science. Since decades, fingerprinting, dactylography, and dermatoglyphics had gained widespread acceptance and known as the answer to individualization, especially in forensic analysis. Individual fingerprints are intricate, one-of-a-kind, and challenging to fake. Their persistent over the period of time,uniqueness, makes them appropriate as permanent identity of Human beings. A fingerprint can easily be employed by any law enforcement or other agencies to locate those who want to hide their identities or in the case of a natural disaster, identify those who are handicapped or dead. This review discuss about the advancement in science of fingerprinting since it started till the current age of digitalization.

Abstract
The synthesize of β-type NbTi50/SWCNTs intermetallic matrix nanocomposite by mechanical alloying (MA) to ensurethe effective distribution of single walled carbon nanotubes (SWCNTs) within the matrix. It has been stated by severalresearchers that during MA of Nb and Ti powder mixtures, NbTi intermetallic compound formation occurs either
gradually along milling time, or suddenly through a mechanically self-propagating reaction (MSPR), which occurs aftera ignition time of MA. For this purpose 0.4 and 0.8 wt% of SWNTs were added to the powder mixture before thecompletion of reaction between Nb and Ti. The resultant powders NbTi50 intermetallic compound with and with a
addition of SWCNTs bulk samples were compacted and then sintered by field actived sintering technic spark plasmasintering method (FAST-SPS) at lower temperature in the range (1273 to 1473 K) with short time that retained theintegrity of SWNTs in the matrix. Structural and characteristics evolutions were investigated by X-ray diffractometery (XRD). field
emission scanning electron microscopy (FESEM) micrographs showed that the offered MA approach caused theSWNTs to uniformly embed in the in situ synthesized NbTi matrix. Meanwhile better distribution of SWCNTs resultedin higher density of FAST-SPS-FCT bulk nanocomposite as well as higher hardness up to 6.6 GPa compared to 6.41 of NbTi50intermetallic obtained from the same MA time. Fracture toughness showed more than 0.5% increase with bridging andpull out of SWNTs and deflection of cracks as toughening mechanisms.
The total porosity, compressive strength, and compressive elastic modulus of the FAST-SPS-FCT manufactured materialwere determined as 17%, 968 MPa, and 33 GPa, respectively. The alloy’s Yungs elastic modulus is comparable to thatof healthy cancellous bone, the in vitro biocomptability will be performed in the néar future).The comparable results for the FAST-SPS-FCT nanocomposites were 3%, 1400 MPa, and 77
GPa. The alloy’s elastic modulus is comparable to that of healthy cancellous bone. This difference in mechanicalproperties results from different porosity and phase composition of the bot β-phase NbTi50 andNbTi50/SWCNTs intermetallic matrix nanocomposite.
More otther nanotechnologies applications of the nanocomposite will be focused in the study of the superonducting type1 for the ITER Poloidal Field Coils by mesuaring of Jc(T, B) characteristics.

When you introduce the word computer science, they don’t know the meaning, just that it’s an app, but what is an app.
Before thinking about creating a mobile application, website, etc; computer science needs to betaken back to the important principles that will get you to your destination. What is the motivation, why does the individual care about the problem and results, what is the problem statement, what problems need to be solved, what is the approach on how to solve the problem statement.
These are scenarios that need to be answeredbefore you can begin to write your source code and be that next rockstar of the app world. The discussion will be around what makes up computer science,how is it taught in the educationfield, the outcomesthat it provides

Abstract
Microplastics are solid plastic particles composed of a mixture of polymers and functional additives. Microplastics can form inadvertently from larger pieces of plastic, such as car tires or synthetic textiles. Once microplastics are dissolved from major plastic products, microplastics can move through wastewater and settle in ecosystems causing pollution. This will affect living organisms in the way they are consumed due to their small size. Accordingly, the coagulation process is one of the ways to treat wastewater so that it is safer to release to the environment. The most commonly used commercial coagulating agent is alum whose use has an impact on the environment. Therefore, this study focuses on the treatment of wastewater containing microplastics through coagulation process using natural coagulant extracted from soybean seeds. In this study, the performance of soy bean seed extract will be compared side by side with comercial coagulant (alum) to coagulate microplastics in wastewater sample and will be evaluated through Total Suspended Solid (TSS) measurment and Fourier Transform Infrared (FTIR) spectrum and. Results obtained from this analysis showed both caogulant (alum and soy seed extract) can coagulate microplastic from the wastewater. However, alum performance showed slightly better sedimentation based on the TSS value. Alum showed more than 90% of TSS removal. On the other hand, soy bean seed extract showed below than 70% TSS removal. Although alum showed better performance, access usage of alum can give negative impact to the environment. Thus, selection of natural coagulant to coagulate microplastics from wastewater is still relevant due to the green and sustainable characteristics showed by natural coagulant.

Abstract
Adopting recycled aggregate concrete (RAC)in the construction industry is an ideal approach to sustainability. However, the properties of RAC need modification before use in practice. Anew physical compression casting (CC) method was used in combination with the treatment of nanomaterials to enhance the properties of RAC. Although using nanomaterials contributed to accelerating hydration, promoting pozzolanic reaction, and increasing calcium-silicate hydrate gel, the enhancement in strength and reduction in porosity was found to be limited. Thus, the CC method was used to compensate for the weaknesses. The effects of CC, nanomaterials, and their combinations on the properties of RAC were investigated. At the macrolevel, the stress-strain responses were evaluated by examing the compressive strength, peak strain,and modulus of elasticity. At the microlevel, the porosity and pore distribution along the interface transition zones (ITZs) were investigated using mercury intrusion porosimetry (MIP) analysis and scanning electronic microscope (SEM) imaging technology. Significant improvements in both macro- and micro-level were reached by the combination using the CC method and nanomaterials.

Abstract
Pure CuO and 2-Dimensional CuO-ZnOnano-composites (NCs) were effectively prepared by an ultrasound-assisted probe sonication route for different ratios of CuO and ZnO, and the structural, photo-catalytic and electrochemical properties were investigated by the experimental and theoretical methods. The XRD (X-ray differation) patterns revealed a crystallite size (D) range of 25 to 31 nm for pure CuO and CuO-ZnO NCs. According to calculations, the sample’s optical energy band gap value (Eg) for the NCs is between 2.15 and 2.48eV. Under UV light irradiation, the photo-catalytic degradation of pure CuO and CuO-ZnO NCs on Direct Green (DG) and Fast Blue (FB) dyes was assessed. The electrochemical analysis of the prepared electrode with graphite powder in 0.1N HCl electrolyte solution demonstrated superior redox potential output as predicted by the cyclic voltammetry experiments. The NCs were employed for their sensing abilities for a highly toxic metal like Arsenic. Based on our study, we came to the conclusion that the CuO and ZnO NCs, containing 10% of ZnO, were the most effective photo-catalyst for DG and FB dyes and electrochemical sensor for Arsenic.

Abstract
The shipping transportation industry plays an important role in developing the economics at each country in the world. With the specific characteristics of maritime transportation, the energy consumption which is presented through the fuel oil consumption is very much. In when, the fuel oil consumption cost possesses mainly per total other operational costs. Besides that, the energy consumption related directly the environmental pollution issue from the ship operation process. In this research, the establishment of remote surveying system of fuel oil consumption has been conducted to help the stakeholders in the maritime transportation. The Internet of Things (IoT) technique has been employed to support this energy surveying system. The validation of this proposed system has been conducted for a certain vessel of shipping transportation company in Vietnam. These research results are very significant in monitoring the energy consumption for ships as well as the ship energy efficiency management.

Abstract
Digital text steganography uses embedding process to conceal messages in text medium to hide information in secret communications. The main goal of steganography is to have secret public information, the capacity or place to hide the secret information with a high perceptual transparency level, a robust steganography media against attacks by eavesdroppers, and protecting the shared secret key and the secret message during transmission. Therefore, the main challenge is to design an efficient steganography algorithm to achieve a secure communication. Moreover, there is the need to consider possible active attacks in order to have high security in steganography communication. This can be achieved via a hybrid steganography having other layers of information and sub disciplines such as cryptography. We will also discuss current research in text steganography, which mostly aim to provide an optimization solution, to increase the robustness of substitution techniques while maintaining the significant capacity of the embedded secret information. Techniques used in this research to achieve the steganography objectives range from machine learning, multilayer security mechanism, multifactor security, substitution, injection, and propagation techniques, encryption, to various embedding techniques.

Historical events: long back in 45-70AD at Rome the dental finding was being used as a evidence first time in forensic manner where king Nero had killed his mother who was identified by 2 canine teeth. Similarly, in 1477, the body of Charles The Bold(last valois duke of Burgandy)was identified on the basis of several missing anterior teeth. Some high-profile cases like Ted Bundy and Adolf Hilter were also identified from bitemark and teeth.Scope and purpose of forensic odontology mainly focuses on identifying unknown human remains through comparison of postmortem dental evidence with dental records of the presumed deceased, age estimation of both living as well as dead, recognition and analysis of bitemarks found on victims or any other foodstuffs, determining the gender of unidentified person, identification of victims in mass disasters cases, presenting evidence in court as expert witness.
