Multidimensional statistical convergence of functions via ideal
RABİA SAVAŞ,R. F. Patterson 장전수학회 2020 Proceedings of the Jangjeon mathematical society Vol.23 No.4
The goal of this paper includes the generalization of the notions of [V,λ,μ] (I2)-double strongly summability and I2 - λμ-double statistical convergence by taking nonnegative real-valued Lebesgue measurable two dimensional functions on (1,∞)×(1,∞). Using these two new notions we established two fundamental inclusion theorems.

The chinch bug, Blissus leucopterus leuco- pterus (Say), has become an important early-season pest of corn, Zea mays L., in the southeastern United States. Information on overwintering of chinch bugs is available but it is primarily from studies conducted in the central and midwestern states. Studies were conducted to describe chinch bug overwintering sites, changes in population densities in bromesedge, Andropogon virginicus L., and the timing of spring and fall flights from and to overwintering sites in a northeastern Mississippi environment during a three year period. Adults were found to over winter in many sites on the study area. High numbers of chinch bugs were found to congregate in bromesedge plants along roadsides or within cut-over woodland. Adults began to move into bromesedge for overwin- tering in September, but the largest increase occurred in October. Winter mortality from December to the end of February was slight probably because of mild winters during the three year study. Adult numbers in bromesedge began to decline in March as insects began to leave the overwintering site, and the rate of evacuation increased rapidly as temperatures warmed in April. Significant negative correlations were found to exist between the decline in numbers of chinch bugs in bromesedge and spring daily average and maximum temperatures. Fall and spring flight to and from overwintering sites based on captures of adults on aerial traps were found to be in general agreement with the timing of adult increase and decline on bromesedge.

Dental pathogens lead to chronic diseases like periodontitis, which causes loss of teeth. Here, we examined the plausible antibacterial efficacy of copper nanoparticles (CuNPs) synthesized using Cupressus macrocarpa extract (CME) against periodontitis-causing bacteria. The antimicrobial properties of CME-CuNPs were then assessed against oral microbes (M. luteus. B. subtilis, P. aerioginosa) that cause periodontal disease and were identified using morphological/ biochemical analysis, and 16S-rRNA techniques. The CME-CuNPs were characterized, and accordingly, the peak found at 577 nm using UV-Vis spectrometer showed the formation of stable CME-CuNPs. Also, the results revealed the formation of spherical and oblong monodispersed CME-CuNPs with sizes ranged from 11.3 to 22.4 nm. The FTIR analysis suggested that the CME contains reducing agents that consequently had a role in Cu reduction and CME-CuNP formation. Furthermore, the CME-CuNPs exhibited potent antimicrobial efficacy against different isolates which was superior to the reported values in literature. The antibacterial efficacy of CME-CuNPs on oral bacteria was compared to the synergistic solution of clindamycin with CME-CuNPs. The solution exhibited a superior capacity to prevent bacterial growth. Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and fractional inhibitory concentration (FIC) of CME-CuNPs with clindamycin recorded against the selected periodontal disease-causing microorganisms were observed between the range of 2.6-3.6 μg/ml, 4-5 μg/ml and 0.312-0.5, respectively. Finally, the synergistic antimicrobial efficacy exhibited by CME-CuNPs with clindamycin against the tested strains could be useful for the future development of more effective treatments to control dental diseases.

Gold nanoparticles (AuNP) and their conjugates have been gaining a great deal of recognition in the medical field. Meanwhile, extended-spectrum β-lactamases (ESBL)-producing bacteria are also demonstrating a challenging problem for health care. The aim of this study was the biosynthesis of AuNP using Rosa damascenes petal extract and conjugation of ceftriaxone antibiotic (Cef-AuNP) in inhibiting ESBL-producing bacteria and study of in vitro anticancer activity. Characterization of the synthesized AuNP and Cef-AuNP was studied. ESBLproducing strains, Acinetobacter baumannii ACI1 and Pseudomonas aeruginosa PSE4 were used for testing the efficacy of Cef-AuNP. The cells of MCF-7 breast cancer were treated with previous AuNP and Cef-AuNP at different time intervals. Cytotoxicity effects of apoptosis and its molecular mechanism were evaluated. Ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy established the formation of AuNP and Cef-AuNP. Transmission electron microscope demonstrated that the formed nanoparticles were of different shapes with sizes of 15~35 nm and conjugation was established by a slight increase in size. Minimum inhibitory concentration (MIC) values of Cef-AuNP against tested strains were obtained as 3.6 and 4 μg/ml, respectively. Cef-AuNP demonstrated a decrease in the MIC of ceftriaxone down to more than 27 folds on the studied strains. The biosynthesized AuNP displayed apoptotic and time-dependent cytotoxic effects in the cells of MCF-7 at a concentration of 0.1 μg/ml medium. The Cef-AuNP have low significant effects on MCF-7 cells. These results enhance the conjugating utility in old unresponsive ceftriaxone with AuNP to restore its efficiency against otherwise resistant bacterial pathogens. Additionally, AuNP may be used as an alternative chemotherapeutic treatment of MCF-7 cancer cells.

The studies on the relative occurrence and abundance of mustard aphid, Lipaphis erysimi (Kalt.) revealed that aphid appeared on leaves during 3rd week of January and on the inflorescences during 2nd week of February and continued up to harvesting on both the varieties. The peak populations (42.7) and (28.7) per leaf on Rainbow and Oscar varieties were recorded. Whereas, the peak populations (7.5) and (6.6) per inflorescences were recorded on these varieties. The higher mean population ranges (9.2 to 28.7) and (25.1 to 42.7) per leaf on Oscar and Rainbow and (3.9 to 6.6) and (2.3 to 7.6) per inflorescence were recorded from February 15 to March 5. The temperature range of 16.5 to $20.6^{\circ}$, seems to have favored the pest multiplication. The predator species such as, green lacewing beetle, Chrysoperla carnea (Stephens), eleven-spotted ladybird beetle, Coccinella undecimpunctata (Linn.) and seven-spotted ladybird beetle, Coccinella septempunctata (Linn.) were recorded when the pest population of aphids was sufficiently developed on the canola varieties.

<P><B>Abstract</B></P> <P>Arsenic (As) is a naturally occurring metalloid and Class-A human carcinogen. Exposure to As via direct intake of As-contaminated water or ingestion of As-contaminated edible crops is considered a life threatening problem around the globe. Arsenic-laced drinking water has affected the lives of over 200 million people in 105 countries worldwide. Limited data are available on various health risk assessment models/frameworks used to predict carcinogenic and non-carcinogenic health effects caused by As-contaminated water. Therefore, this discussion highlights the need for future research focusing on human health risk assessment of individual As species (both organic and inorganic) present in As-contaminated water. Various conventional and latest technologies for remediation of As-contaminated water are also reviewed along with a discussion of the fate of As-loaded waste and sludge.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Arsenic is recognized as a Class-A human carcinogen. </LI> <LI> Groundwater As contamination has affected over 200 million people worldwide. </LI> <LI> This paper reviews current knowledge regarding As in the environment. </LI> <LI> A critical assessment of remediation of contaminated water is presented. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
