This study of semiconductor laser structure works on reducing the value of the threshold current density to improve the working conditions of the laser device. In this paper shown that the threshold current density and Optical confinement factor Г depends on Barrier width (B), and Number of well (Nw). We found any increase in Barrier width and Number of well is enhanced important parameters of diode laser such as threshold current density and confinement factor that's clearly for (Nw=2, B=40 nm) then (Г=0.175, ), while for (Nw=2, B=60 nm), that give results are (Г=0.195, ). On the other hand when changing Nw=3, the results become for (B=40 nm and B=60 nm), as follows (Г=0.275, and (Г=0.295, respectively. This investigated contributed to calculating the efficiency and work of the laser device. We found the value of slope efficiency equal (45 %) and the external quantum efficiency (50%).

Published: February 2023

A dominating set S V is said to be an Antipodal Dominating Set(ADS) of a connected graph G if there exist vertices x, y S such that d(x, y) = diam(G). The minimum cardinality of an ADS is called the Antipodal Domination Number(ADN), and is denoted by γap(G). In this paper, we determined the antipodal domination number for various graph prod- ucts, bound for antipodal domination and characterize the graphs with γap(G) = 2.

Published: February 2023

Given a distribution of pebbles on the vertices of a connected graph G, a pebbling move is defined as the removal of two pebbles from some vertex and the placement of one of those pebbles on an adjacent vertex. The t - pebbling number of G is the smallest number, ft(G) such that from any distribution of ft(G) pebbles, it is possible to move t pebbles to any specified target vertex by a sequence of pebbling moves. The detour pebbling number of a graph f ∗(G) is the smallest number such that from any distribution of f ∗(G) pebbles, it is possible to move a pebbles to any specified target vertex by a sequence of pebbling moves using a detour path. In this paper, we find the detour pebbling number for some Cartesian product graphs and also the detour t - pebbling number for those cartesian product graphs.

For any graph G(V, E), a function f : V (G) 0, 1, 2, 3 is called Double Roman dominating function (DRDF) if the following properties holds, If f (v) = 0, then there exist two vertices v1, v2 ∈ N (v) for which f (v1) = f (v2) = 2 or there exist one vertex u ∈ N (v) for which f (u) = 3.∈ If f (v) = 1, then there exist one vertex u N (v) for which f (u) = 2 or Σ f (u) = 3. The weight of DRDF is the value w(f ) = v∈V (G) f (v). The minimum weight among all double Roman dominating function is called double Roman domination number and is denoted by γdR(G). In this article we initiated research on double Roman domination number for middle graphs. We established lower and upper bounds and also we characterize the double Roman domination number of middle graphs. Later we calculated numerical value of double Roman domination number of middle graph of path, cycle, star, double star and friendship graphs.
Natural and Anthropogenic Impacts on the Macrophytes of Soft-Water Lakes of Estonia
Authors: Mäemets Helle 
Published: February 2023

Oligotrophic and semidystrophic lakes (water alkalinity <80 mg HCO3− L−1; dichromate oxygen consumption <40 mg O L−1) are the main habitats for rare macrophytes, especially isoetids. They are characteristic for the lakes with HCO3− ≤ 30 mg L−1; the higher alkalinity and related higher trophy level support elodeids. Anthropogenic impact on these lakes in Estonia started with flax retting and water lowering and continued with sauna building, agricultural nutrients, and holiday activities. The present overview is based on the data of the last 50 years. Anthropogenic acidification of Estonian lakes is not known, but natural dystrophication due to the inflow of humic compounds is probable. Alkalization and eutrophication are closely related, amplifying each other, and water level modifies these processes. Eutrophication increases the occupation of shallow zone by emergent belts, suppression of isoetids by elodeids, and overshadowing by phytoplankton blooms in a deeper zone or host plants by macroalgae. Fast-growing eutraphents accelerate the accumulation of organic sediments, unfavorable for isoetids. Among floating-leaved plants hybridization between rare and common species as well as introgression takes place. It is almost impossible to reverse back ecosystems that formed and balanced over thousands of years and became unbalanced during a much shorter period. Easier would be to keep functioning ecosystems.

Purpose: The study investigated the availability and accessibility of multimedia resources for teaching and learning Senior High School (SHS) mathematics. It also investigated how SHS mathematics teachers perceive their ability to use multimedia resources in teaching mathematics as well as the effect of gender on teachers’ perceived ability to use multimedia resources.
Methodology: The research design used was a survey. The population for the study was all Public SHS mathematics teachers in the Central, Eastern, and Volta regions of Ghana. Purposive (non-probability) sampling and Convenience (non-probability) sampling methods were used in selecting twelve (12) schools in the three (3) regions and all the mathematics teachers in these schools formed the sample for the study. A questionnaire was used to collect data from the teachers sampled. This was comprised of seventy-three (73) teachers, sixty-four (64) males, and nine (9) females from these three district types: twenty (20) District Assemblies, thirty-three (33) Municipal Assemblies, and twenty (20) Metropolitan Assemblies.
Findings: The study found that most of the teachers surveyed had a high perception of their ability to use computers and multimedia to teach mathematics at the SHS level. However, their perceived ability to use multimedia resources was higher for general-purpose applications; peripherals were higher than that of special mathematics applications software. There was no statistically significant difference between gender and teachers’ perceived ability to use multimedia resources. About half, representing 49.3% of the teachers indicated that they have Computer and Computer Laboratories in their schools but without internet connectivity. The labs were accessible for teaching and learning mathematics.
Conclusion: The study conclude that gender, age, teaching experience, and school location have no significant influence on the use of multimedia by mathematics teachers.
Recommendations: The study recommend more females to be encouraged to pursue mathematics related disciplines at the higher levels of education. Also, the use of more multimedia tools should be incorporated into the curriculum so that teachers will be encouraged to use them frequently in the classroom. Education institution development should be overseen by stakeholders like parents, philanthropists, or donor organizations.

Sampling method used was purposive and simple random sampling purposive and simple random sampling was used for data collection. Lastly, AMOS version 26 was used for data analysis. The Kaiser-Meyer-Olkin test was used to measure sampling Adequacy. Mahalanobis' distance (MD) as a statistical measure based on a chi-square distribution was employed to check the extent to which cases are adjusted with multivariate outliers. SEM model fitness results showed the complete mediation i.e the entire (or total) effect of Promotion Mix Elements on a Customer Buying Behavior is transmitted through Customer Satisfaction. Therefore, the Promotion Mix Elements have no direct effect on the Customer Buying Behavior; rather, its entire effect is indirect. Therefore, mediation role of Customer Satisfaction was really happening in a given model, but the total effect is significant simply because the sample size is very large, or assumptions for the test of the total effect were met.
