Published: May 2023

In this digital world, technology is changing every second. For this reason, tech-based educational departments should be aware of their strong and weak areas. By doing so, they can analyze their performance and emphasis the respected fields to prepare their students for the challenging job market and higher studies. In this research, a novel machine learning model is proposed to predict the performance of computer science department students by analyzing their academic statements. The academic areas of the departments are divided into fifteen fields, each of which is categorized as Excellent, Very Good, Good, Average, and Bad. One thousand students’ academic statements were used as the dataset. The prediction outputs are labeled into multiple categories, with multiclass data in each. Different models are developed using multiclass-multioutput classification algorithms like Decision Tree (Tree), Extra Tree (Tree), Extra Trees (Ensemble), K-Neighbors (Neighbors), Radius Neighbors (Neighbors), and Random Forest (Ensemble) Classifier. From the developed models, the model that used "Random Forest Classifier (Ensemble)" provided the best results, and the accuracy was almost 94%. Finally, a comparison of our research with previous and existing different developed models is presented to show the novelty of this research.
Organotitanium Click Chemistry
Authors: G. Arzoumanidis Gregory
Published: May 2023

The click chemistry of titanium exemplified by the “green” [3 + 2] cycloaddition of the [Ti-N3] moiety with nitriles RCN to form a tetrazole ligand, is currently limited in scope, but the future of this open and wide field is bright, full of promising new synthetic approaches discussed herein, for pharmacological and bio orthogonal applications. This prediction is based on emerging click reaction possibilities from newly prepared titanium azides (complex 6), to existing titanium azides, including the commercially available Ti(N3)4, Cp2Ti(N3)2, (iPrO)2Ti(N3)2, and their multiple derivatives, participating in cycloaddition, exchange and other reaction types with alkynes, alkenes, nitriles, and related click synthons. Most of the organotitanium click reactions show nearly quantitative yields, as in the reaction of Ti(OiPr)4 with (CH3)3SiN3. Structural, mechanistic, stereo control and other effects on reactivity are briefly discussed. The main emphasis in this review article is on recently discovered organotitanium complexes like 2-phenylindole titanium dichloride, easily modified by insertion reactions of small molecules like CO2, SO2 or even RN3, serving as springboards of a new era in organotitanium click chemistry, by the original syntheses of non-toxic, potentially bioactive complexes.

A Theoretical Justification for Treating the Contract for Deed as a Mortgage
Authors: Blaney Matthew J.
Published: May 2023

Millions of Americans finance their home using the treacherous contract for deed. Denied access to the conventional mortgage, the contract for deed often is the only alternative for Americans seeking the stability of homeownership. Historically, however, this deceptive financing device disrupted the lives of thousands of individuals by forfeiting their property and all payments made on the contract—even where only one installment was overdue. Low-income Americans and immigrant families disproportionately experience the brunt of the contract for deed. Furthermore, as Americans experience rising prices and increasing financial instability, there is reason to fear sellers—equipped with insight into lenders’ former mistakes—could revive the contract for deed, using it to swindle unsuspecting buyers. Several scholars previously addressed the necessity of treating the contract for deed as a mortgage. However, none addressed the critical underlying question: What is property, and what role does it play in society? This Article analyzes natural law, personhood, utilitarian, and civic republican theories of property as applied to the dilemma of the forfeiture clause. Whether it is because of the stifling of community, the destruction of an individual’s external sphere of freedom, or the inhibiting of a citizen’s ability to participate in democracy, channeling the insight of some of the world’s greatest philosophers compels the conclusion that change is necessary. Lastly, courts are not without guidance. The Indiana & Kentucky Supreme Courts established clear doctrine treating the contract for deed as a mortgage. Thus, given that enforcing forfeiture clauses in contracts for deeds is incongruent with the philosophical foundations of property law, it is time for society to follow the Indiana and Kentucky approaches and treat this financing device as a mortgage.
Until the Cows Come Home: Ancillary Probate Reform is Needed Across the Country to Better Serve Farmers and Ranchers
Authors: Daniel Emily K.
Published: May 2023

Property law has long established a difference between real and personal property. When an individual dies, if they owned real property in another state, they may be subject to the other state’s probate or estates code. This means that the decedent’s beneficiaries may have to probate the estate again in the secondary state’s courts if the statutes state that is a requirement. This secondary probate proceeding is called ancillary probate. This Article aims to show the negative effects that ancillary probate has on certain people and industries. Specifically, ancillary probate is a problem that negatively affects farmers and ranchers across the nation due to increased costs and time, problems with estate planning, and the effects it has on the individual needs of families. Because farming and ranching is a vital industry to the survival of the United States, reform is needed to increase uniformity across state codes. This Article demonstrates why uniformity will better serve those who farm and ranch when they own land in another state at the time of death. The original contribution to scholarship is showing how the effects of ancillary probate affect farmers and ranchers and proposing that states should adopt an estates code that mimics the Texas Estates Code. This Article urges states to not only adopt a code provision that better serves the farming and ranching industry but to adopt a provision that mimics Texas Estate Code sections. This Article shows why ancillary probate is an increasing problem for farmers and ranchers while also showing why this group is important to the country. It displays the importance of this group of people and why measures should be taken to protect their ability to be on the land and to farm. Lastly, this Article aims to encourage states to adopt a new provision by showing the negative effects that the current system has on this industry by highlighting necessities that are the product of this industry.

Published: May 2023

The segment of a highway located in mountains is under investigation. One side of the segment under study adjoins to the rock. This construction under examination is based on high-capacity columns. This segment is considered as semi-infinite cantilever plate made from isotropic or constructive-orthotropic material. It is assumed that the thickness of this plate varies in one direction. The present work suggests the analytical method of computation. An influence of columns on the semi-infinite cantilever plate with varying thickness is considered as an action of a system of concentrated forces or systems of forces distributed along short straight lines and over surfaces of rectangulars. The solutions are received in closed forms.

Published: May 2023

The effect of calcium hexaboride on the interaction of HfB2 and TaB2 with iridium was studied as a function of temperature and the ratio of initial reagents. It is shown that the replacement of half of the transition metal diboride by CaB6, as well as an increase in temperature, lead to a significant change in the phase composition of the products. In all mixtures, the formation of calcium-iridium-containing phases is observed. The introduction of CaB6 suppresses the formation of some hafnium and tantalum ternary borides, as well as tantalum intermetallide. The result must be taken into account when developing high-temperature materials.

The results of crystallization of glass powders of the diborate section of the Na2O BaO B2O3 system are presented. The glass transition temperatures and temperature regions of crystallization at a heating rate of 10 K/min were determined by DTA and XRD methods; the formed crystalline phases were identified, and the nature and temperatures of their melting were established. It is shown that the section under study is not a pseudobinary system, but only a partial section of the sodium-barium borate system. It is shown that the Na2O·2BaO·9B2O3 compound is the phase of primary crystallization in the section; its field covers the majority of the section. The second known ternary compound, Na2O·2BaO·5B2O3, apparently melts peritectically. It has been established that during long-term heat treatment of glasses in a monolithic state, a new phase is formed in them with an approximate composition of Na2O·2BaO·6B2O3.

Within the framework of the semiclassical atomistic approach and our model based on oxygen octahedrons, we performed computer simulation of the processes of ordering of structural units that occur during the formation of energetically equilibrium oxygen-octahedral clusters in nominally pure and doped crystals in a lithium niobate (LiNbO3) crystal with different Li/Nb ratio. It is shown that there is an energetically favorable size of a cluster, having an energy optimum, within which a certain structure is organized, tending to the structure of a congruent crystal. It was also determined that, due to the loss of electroneutrality, a cluster of strictly stoichiometric composition cannot exist.

Doping a charge of congruent composition (R = [Li]/[Nb] = 0,946) by boric acid leads to an increase in stoichiometry (R = 0,96) of the LiNbO3:B (144·10-5 wt % B in the cone) crystal. The LiNbO3:B crystal was studied by the X-ray diffraction analysis. It was found that in the LiNbO3:B crystal there are no NbLi defects, but there are NbV defects. It has been shown that the localization of the boron cation in the structure of the LiNbO3:B crystal near the NbV defect will be most preferable in the faces of vacant tetrahedral voids common with lithium or vacant oxygen octahedra O6.

38 samples were synthesized in the Na2O-BaO-B2O3 system, some of which were glasses, some crystallized. The degree of interaction of the initial reagents in the synthesis process was controlled by X–ray phase analysis on a DRON-3M diffractometer using CuKa radiation. Crystal phases were identified using X–ray phase analysis on a DRON-3M diffractometer using CuKa radiation and the PDF–2 powder diffractometry database. The following crystalline phases were identified in the crystallized samples: β-BaВ2O4, NaBO2, NaBaB9O15. Density, microhardness, refractive index were measured for glassy samples of the system under study and melting/liquidus temperatures were determined. It is established that the nature of the dependence of the above properties on the content of sodium oxide with a constant content of boron oxide is linear. The study of vaporization processes and thermodynamic properties of the Na2O-BaO-B2O3 system was carried out by differential high-temperature mass spectrometry on the MS–1301 mass spectrometer. The studied samples were evaporated from a twin Knudsen molybdenum effusion cell. The heating of the cell was carried out by electronic bombardment, the temperature was measured with an optical pyrometer EOP–66. It was shown that as a result of the interaction of Na2O, BaO and B2O3 oxides, sodium and barium borates are formed in the condensed phase. It is established that the studied system is characterized by selective evaporation of NaBO2 in the temperature range of 1290–1350 K. The activity values of NaBO2 and B2O3 were determined depending on the composition of the condensed phase at a temperature of 1330 K. The activity of BaB2O4 was calculated using the Gibbs-Dugem equation. The obtained values of the Gibbs mixing energies and excess Gibbs energies indicate significant deviations of the Na2O-BaO-B2O3 system from the ideal behavior.

The problems of studying low-temperature phase formation in systems, which are the basis for obtaining functional materials, are selected. The use of salt fluxes (alkali metal nitrates and sulfates) is an effective method of accelerating the achievement of equilibrium in fluoride and oxide systems. Extrapolation of phase equilibria to absolute zero temperature, taking into account the requirements of the third law of thermodynamics, is a powerful method for obtaining relevant information. Summary phase diagrams of the ZrO2-Sc2O3 and albite — anorthite systems are proposed.

The effect of thermally activated clays on the processes of hydration, structure formation and strength properties of cement stone is analyzed. It has been shown that polymineral clay fired at 500 and 600 °C makes it possible to replace up to 5–10 % of Portland cement without loss of strength of the composite cement stone. All samples showed strength at 28 days of age in the range of 102–105 MPa, which is 25 % higher than the strength of the control composition. The presence of thermally activated clays in the cement stone promotes the formation of low-basic calcium hydrosilicates and the formation of a dense structure.

The service life of vitrification furnaces is limited, as a rule, not by poor condition of the entire refractory brickwork but rather by damage (frequently accidental one) to a limited number of structural elements of the melting tank and gas plenum located in the melting zones and zones of maximum temperatures. Borosilicate glass is characterized by a higher melting temperature and increased corrosion activity. The paper presents the test results related to the study of corrosion activity of refractory materials in borosilicate glass melts.
