unreinforced masonry buildings
A recent earthquake of M=4.9 occurred on 29 October 2007 in C, ameli, Denizli, which is located in a seismically active region at southwest Anatolia, Turkey. It has caused extensive damages at unreinforced masonry buildings like many other cases observed in Turkey during other previous earthquakes. Most of the damaged structures were non-engineered, seismically deficient, unreinforced masonry buildings. This paper presents a site survey of these damaged buildings. In addition to typical masonry damages, some infrequent, event-specific damages were also observed. Reasons for the relatively wide spread damages considering the magnitude of the event are discussed in the paper
Search for the anomalous and gauge couplings through the process with unpolarized and polarized beams
This work offers the constraints on the anomalous neutral triple gauge
couplings (aNTGC) for the process at the CLIC with
TeV. The realistic CLIC detector environments and their effects
are considered in our analysis. The study is planned for the decays of
producted bosons to a pair of charged leptons (electrons or muons) and
neutrino pairs. The bounds on the aNTGCs defining -conserving
coupling and three -violating
, , and couplings
are obtained. Also, the effects and advantages of polarization for incoming
electron beams in these calculations are investigated.Comment: 21 pages, 14 figure
Graphene and Related Materials for the Internet of Bio-Nano Things
Internet of Bio-Nano Things (IoBNT) is a transformative communication
framework, characterized by heterogeneous networks comprising both biological
entities and artificial micro/nano-scale devices, so-called Bio-Nano Things
(BNTs), interfaced with conventional communication networks for enabling
innovative biomedical and environmental applications. Realizing the potential
of IoBNT requires the development of new and unconventional communication
technologies, such as molecular communications, as well as the corresponding
transceivers, bio-cyber interfacing technologies connecting the biochemical
domain of IoBNT to the electromagnetic domain of conventional networks, and
miniaturized energy harvesting and storage components for the continuous power
supply to BNTs. Graphene and related materials (GRMs) exhibit exceptional
electrical, optical, biochemical, and mechanical properties, rendering them
ideal candidates for addressing the challenges posed by IoBNT. This perspective
article highlights recent advancements in GRM-based device technologies that
are promising for implementing the core components of IoBNT. By identifying the
unique opportunities afforded by GRMs and aligning them with the practical
challenges associated with IoBNT, particularly in the materials domain, our aim
is to accelerate the transition of envisaged IoBNT applications from
theoretical concepts to practical implementations, while also uncovering new
application areas for GRMs
A Patient with Proopiomelanocortin Deficiency: An Increasingly Important Diagnosis to Make
Proopiomelanocortin (POMC) deficiency is a rare monogenic disorder with early-onset obesity. Investigation of this entity have increased
our insight into the important role of the leptin-melanocortin pathway in energy balance. Here, we present a patient with POMC
deficiency due to a homozygous c.206delC mutation in the POMC gene. We discuss the pathogenesis of this condition with emphasis
on the crosstalk between hypothalamic and peripheral signals in the development of obesity and the POMC-melanocortin 4 receptors
system as a target for therapeutic intervention
Effects of Nigella sativa seeds and certain species of fungi extracts on number and activation of dural mast cells in rats
In this study, we aimed to investigate the effects of Nigella sativa seeds and certain species of fungi extracts on the number and degranulation states of dural mast cells in rats. Rats were fed ad libitum with normal tap water or tap water with extract of N. sativa seed, Ramaria condensata, Lactarius salmonicolor, Lactarius piperatus, and Tricholoma terreum for 3 days. Mast cells in dura mater were counted and evaluated in terms of granulation and degranulation states. Compound 48/80, a mast cell degranulating agent, and T. terreum significantly increased the percent of degranulated mast cells in dura mater, respectively (p < 0.01 and p < 0.05). Moreover, T. terreum causes a significant increase in the total number of mast cells (p < 0.05). N. sativa significantly inhibited mast cell degranulation induced by both the compound 48/80 and T. terreum (p < 0.05), and significantly decreased the mast cell numbers increased by T. terreum (p < 0.05). Our results suggested that T. terreum following ingestion can contribute to headaches like migraine via dural mast cell degranulation and N. sativa may be able to exert analgesic and anti-inflammatory effects by stabilizing dural mast cells. However, investigation is needed to determine the ingredients of N. sativa that may be responsible for these beneficial effects
FREQUENCY RATIO ASSESSMENT FOR LANDSLIDES TRIGGERED BY 6 FEBRUARY 2023 KAHRAMANMARAS TURKIYE EARTHQUAKES BETWEEN GOLBASI AND ERKENEK
Landslides triggered by earthquakes are significant geological hazards that can have devastating consequences, posing risks to human lives, infrastructure, and the environment. These seismic events may cause the instability of slopes and result in the displacement of soil and rock materials, leading to landslides. It is crucial to understand the characteristics and mechanisms of earthquake-triggered landslides in order to effectively manage and mitigate their associated risks. The number of landslides triggered by the 2023 KahramanmaraÅŸ earthquakes (with magnitudes of 7.7 and 7.6) was over three thousand and their destructive effects were also devastating as secondary hazards. This study aims to examine the characteristics of landslides using the frequency ratio (FR) model. A landslide susceptibility map (LSM) was also produced using the output. For this purpose, in this study, we derived landslides triggered by the earthquakes in a part of the earthquake-affected region, between Golbasi town of Adiyaman and Erkenek village of Malatya covering an area with a size of 625 km2. The study utilized a landslide inventory that was manually delineated by visual interpretation based on pre-event and post-event. These associations can serve as a foundation for the application of various data-driven machine learning techniques. The findings of this study will contribute to the development of accurate LSMs, providing crucial insights into the behavior of earthquake-triggered landslides
