Long-Term Monitoring of Bright Blazars in the Multi-GeV to TeV Range with FACT

Blazars like Markarian 421 or Markarian 501 are active galactic nuclei (AGN), with their jets orientated towards the observer. They are among the brightest objects in the very high energy (VHE) gamma ray regime (>100 GeV). Their emitted gamma-ray fluxes are extremely variable, with changing activity levels on timescales between minutes, months, and even years. Several questions are part of the current research, such as the question of the emission regions or the engine of the AGN and the particle acceleration. A dedicated longterm monitoring program is necessary to investigate the properties of blazars in detail. A densely sampled and unbiased light curve allows for observation of both high and low states of the sources, and the combination with multi-wavelength observation could contribute to the answer of several questions mentioned above. FACT (First G-APD Cherenkov Telescope) is the first operational telescope using silicon photomultiplier (SiPM, also known as Geigermode—Avalanche Photo Diode, G-APD) as photon detectors. SiPM have a very homogenous and stable longterm performance, and allow operation even during full moon without any filter, leading to a maximal duty cycle for an Imaging Air Cherenkov Telescope (IACT). Hence, FACT is an ideal device for such a longterm monitoring of bright blazars. A small set of sources (e.g., Markarian 421, Markarian 501, 1ES 1959+650, and 1ES 2344+51.4) is currently being monitored. In this contribution, the FACT telescope and the concept of longterm monitoring of bright blazars will be introduced. The results of the monitoring program will be shown, and the advantages of densely sampled and unbiased light curves will be discussed.
WHEY PROTEIN AND ANABOLIC STEROIDS: CURRENT TREND AND FUTURE POTENTIAL EFFECT ON THE HEART. BIOCHEMICAL, HISTOLOGICAL, AND IMMUNOHISTOCHEMICAL STUDY

Background: Whey protein (WP) is considered an ergogenic aid for athletes to improve muscle performance and recovery after sports. Because of its anabolic properties and potential to improve exercise tolerance, Nandrolone Decanoate (ND) is one of the most often abused anabolic steroids among bodybuilders worldwide. Objective : This study aimed to evaluate the possible toxic effects of WP and ND on the heart of adult male albino rats. Methods : Thirty mature male albino rats were separated into four main groups; Control Group: (15 rats) were classified into three equal subgroups: control negative (CN): fed a regular diet and tap water. Control distilled water (CDW): received 2ml/kg/day of distilled water orally. Control peanut oil (CP): received intra-peritoneal peanut oil 0.5 ml/rat onceweekly. WP group: (5 rats) received WP orally at a dose of 5.4g/kg/day. Nandrolone decanoate group (ND): (5 rats) received ND intra-peritoneal at a dose of 36mg/kg once weekly. Combined group (Comb): (5 rats) received WP and ND at the same doses. All animals were euthanized after eight weeks, and blood samples were obtained for study. The heart was preserved for biochemical and histological examination. Results : WP and ND proved to have significant toxic effects on blood parameters and histopathological changes in the heart. Conclusion : These findings support that the heart is highly sensitive to WP and ND administration, and it is necessitated careful administration of dose and for such period under medical supervision for better health
Ordering mechanism and quantum anomalous Hall effect of magnetically doped topological insulators

We investigate magnetic ordering and the quantum anomalous Hall effect (QAHE) in Crdoped topological insulators (TIs) using systematic first-principles calculations, explaining the mechanism responsible for ferromagnetic order and the reason why Sb2Te3 is a better QAHE host than Bi2Se3 or Bi2Te3. We conclude that these magnetic topological insulators have relatively long-range exchange interactions within quintuple layers, and weak interactions between quintuple layers. Our analyses for the spin splitting of the topological surface states suggest that the temperature at which the QAHE occurs in these materials can be significantly enhanced by Mo-Cr co-doping.

Hazardous Genomic Bioeffects of Home Wi-Fi Systems

Objective of this study is to investigate the changes of gene expression in rat brain induced by 2,4 GHz wireless radiofrequency electromagnetic field (WiFi -RF EMF). Total RNA was extracted immediately and purified from the rat brain, after 12 hours/day exposed or sham-exposed to a frequency of 2,4 GHz WiFi –RF- EMF for 14 days. Roche-Nimblegene-Agilent Microarray System was applied to investigate the changes of gene expression in rat brain. Roche-Nimblegene-Agilent Genespring Software for Microarray Analysis was used in bioenformatic analysis. After 14 days of WiFi -RF EMF exposure, 69 genes in experimental group showed statistical significant down regulation compared with the control group. Ten genes in experimental group showed statistical significant up regulation compared with the control group. In this study, it was detected that WiFi -RF EMF exposure to brain cells resulted with the down and up regulation of transcription level of some important genes.
Experimental investigation of cage motions in an angular contact ball bearing

The commonly known effects of both the rotating speeds and external loads on the bearing dynamics or life behaviors are mostly caused by its cage dynamics, because of the complicated contact and collision interactions between the cage and other parts such as the inner or outer rings and balls. In this paper, experimental investigation of dynamic motions of a cage is carried out under various rotating speeds and external loads in a ball bearing. On a bearing test rig, the cage motions in axial and radial directions are measured by use of eddy transducers installed inside the bearing house and the subpanel. Then the measured results are analyzed by fast Fourier transform and compared at different operating conditions including rotating speeds, axial and radial forces, or moments. The three-dimensional space motions of the cage are also constructed to illustrate its different modes. Results reveal that the cage motions are typically periodic in the three directions. The motion frequencies consist of the cage rotating frequency and its multi-frequency, the inner ring rotating frequency, and also some combination frequencies of the cage and inner ring. The obtained characteristic frequencies of the cage motion in axial are similar to that in radial, but different in the variety of amplitudes under the same operating conditions. The increment of rotating speeds and axial loads of the bearing gradually make the whirl trajectories of the cage mass center regular, and enlarge its whirl radii. Instead, the whirl trajectories change from well-defined patterns to complicated ones, and its whirl radii decrease on increasing the radial loads and moments of the bearing. All the obtained experimental results are useful references for dynamic design and life prediction of high-speed and low-load bearings commonly used in many machines.
Assessment of the Radiation Exposure and Cancer Risks of Disabled People Undergoing Different Computed Tomography Scans

The usage of radiological investigations is increasing rapidly in Saudi Arabia. It has been estimated that 7.1% of the populace in the Kingdom of Saudi Arabia is disabled. Out of 32.94 million citizens, 1,445,723 (52.2% males and 47.8% females) millions are considered disabled. Disabled individuals are frequently undergoing medical imaging procedures, and there are not enough studies regarding the risk of radiation exposure to disabled patients from these machines. This study aims to quantify the frequency of medical procedures and estimate the collective dose for disabled individuals to predict the overall cancer risk from medical exposure. A total of 108 computed tomography (CT) procedures were carried out for disabled patients. The procedures include the brain, chest, abdomen, pelvis, and cervical spine. A 128-slice CT machine was used in this study Philips Ingenuity (Philips, Netherlands). The CT machine is subjected to regular quality control tests to ensure compliance with national recommendations. In this study, 108 [11 (10.2%) females and 97 (89.8%) males] CT procedures were carried out for disabled patients at the radiology department, King Khalid Hospital and Prince Sultan Center. The average and standard deviation radiation dose per CT procedure [DLP (mGy.cm)] for the brain, chest, abdomen, pelvis, and cervical spine were 1183.4 ± 187, 352.8 ± 88, 654 ± 73, 803 ± 800, and 527 ± 186, respectively. The estimated cancer risk is 1 cancer per 1000 to 10,000 CT procedures. Patient doses are comparable with those of previous studies carried out for normal patients. However, the protection of disabled patients from unnecessary radiation exposure is crucial to reduce the projected radiation risks and minimize the number of repeated CT scans and unproductive radiation exposure.

Pure- N -representability conditions of two-fermion reduced density matrices

We derive necessary conditions for any 2-fermion reduced density matrix (2-RDM) to be representable by a pure N -fermion density matrix ΨΨ ∗ where Ψ is the wave function. These pure N -representability conditions of the 2-RDM are important because they provide stringent constraints beyond those from the Pauli and the generalized Pauli constraints on the structure of many-fermion 2-RDMs and their wave functions. The pure 2-RDM conditions are derived as generalized Pauli constraints on eﬀective one-fermion reduced density matrices (1-RDMs) generated by the removal or addition of a fermion from the wave function. Computationally, we show for 4-electron molecules that the derived pure N -representability conditions are non-trivially active for exact ground-state 2-RDMs and that they provide signiﬁcant restrictions beyond the D, Q, and G ensemble N -representability conditions. Constraints on higher-order p -RDMs where p > 2 are derived in a similar fashion. The constraints have potentially signiﬁcant applications to computing strongly correlated many-fermion states with enhanced accuracy and decreased computational complexity.
Economic evaluation of bailing capsules for patients with diabetic nephropathy in China

Background: Diabetic nephropathy is a major microvascular complication and the main cause of end-stage renal disease in diabetic patients. The therapeutic effects of Bailing capsules for diabetic nephropathy have already been demonstrated; however, the cost-effectiveness of Bailing capsules remains controversial. This study aimed to evaluate the cost-effectiveness of Bailing capsules combined with Western medicine compared with Western medicine alone in diabetic nephropathy from a Chinese healthcare system perspective. Methods: A Markov model was established to simulate the disease process of patients over a 20-year period. Clinical efficacy data were obtained from a meta-analysis, and transition probability was estimated based on microsimulation. Direct costs and utility values were collected from the Chinese Drug Bidding Database (https://www.shuju.menet.com.cn) and published literature. The incremental cost-effectiveness ratio (ICER) was measured, and one-way and probabilistic sensitivity analyses were performed to observe model stability. Results: A total of 34 randomized controlled trials involving 3,444 patients with diabetic nephropathy were selected for the meta-analysis. Compared to Western medicine alone, the addition of Bailing capsules resulted in an increase of 0.39 quality-adjusted life-years (QALYs) and additional costs of Chinese Yuan (CNY) 24,721, yielding an ICER of CNY 63,001 per QALY gained. The ICER was lower than the threshold of willingness-to-pay of CNY 80,976 (The GDP per Capita in China). The reliability and stability of the results were confirmed by the sensitivity analysis. Conclusion: We found that Bailing capsules may be a cost-effective treatment choice for patients with diabetic nephropathy in the Chinese population.
Phytochemical Screening and Antibacterial Activity of Chrysophyllum albidum Collected in Nsukka, South East Nigeria

Background: Chrysophyllum albidum is widely used by African people for the treatment of various types of diseases such as ear infection, sore throat, typhoid, cellulites, septicaemia, bactericemia, abscesses and tooth infections. Aim: The study was conducted to investigate the chemical components and antibacterial activity of the extract and fractions from the root bark of Chrysophyllum albidum from Nsukka, South-east Nigeria. Methodology: The fresh roots were collected, washed, cut into small pieces, air dried and pulverized to powder using mechanical grinder. Extraction and fractionation were done by cold maceration method and technique of liquid–liquid extraction respectively. The phytochemical analysis of the methanol extract and, n-hexane, butanol, aqueous and ethylacetate fractions of the plant part was carried out using standard method. The antibacterial activities were determined using cup-plate agar diffusion and agar dilution methods. Results: The phytochemical screening of the extract revealed the presence of tannins, flavonoids, saponins, terpenoids, alkaloids, reducing sugar and cardiac glycosides. The inhibition zone diameter (IZD) produced by the agents against some selected Gram positive bacteria (GPB) and Gram negative bacteria (GNB) pathogens ranged from 6 – 25 mm and 6 – 12 mm respectively. The MIC and MBC values produced by the extract and fractions of the plant’s part against the GPB ranged from 1.25 – 40 mg/ml and 5 – 80 mg/ml respectively Many of the GNB were not sensitive to the agents tested except Pseudomonas aeruginosa and Klebsiella spp that exhibited mild to moderate sensitivity to the agents. Conclusion: These agents, therefore, exhibited a potent antibacterial activity against all the GPB and a few GNB pathogens tested due to their potent phytochemicals. The results of this work have corroborated the trado-medical use of root of Chrysophyllum albidum for treating ear infection, sore throat, typhoid, cellulites, septicaemia, bactericemia, boils and tooth infection/decay.
An Online Adaptive Damping Controller for Converter-Interfaced Generation

The increasing integration of converter-interfaced generation within large-scale synchronous power systems is presenting both new challenges and opportunities in how we operate these dynamical networks. One of these challenges is designing and parameterizing the digital control loops that dictate the dynamical behavior of these fast-acting resources. Improperly tuned gains, or unexpected controller couplings through the network, can lead to poorly damped oscillations during disturbance conditions and/or decrease the system stability margin. Within this work, we present an approach for adaptively tuning a damping controller to improve the dynamic response of converter-interfaced generation, based only on local measurements. We show that, with low-amplitude probing, we can identify a subset set of observable system modes. We then propose a linear MISO state-feedback controller to improve the damping ratio and stability margin of the system. We show the effectiveness of the proposed controller through both eigenvalue analysis and time-domain simulations. We first demonstrate the proposed approach on a simple 3-bus system followed by a larger test case, the IEEE 14 bus system, with multiple devices simultaneously probing the network.
Working mothers in Greece during the COVID-19 pandemic: The conceptualization of “good motherhood” in conditions of lock-down and teleworking

The onset of the COVID-19 pandemic in Greece in March 2020 caused many changes in daily life. Mothers’ duties increased dramatically during the pandemic, as external childcare support was practically non-existent. Working mothers had to manage their different roles and identities at the same time, with teleworking becoming mandatory. This article aims to understand how contemporary working mothers in Greece conceptualize “good motherhood”, taking into consideration the particularities of the pandemic. Eight working mothers with children between the ages of 3 and 18 from various parts of Greece responded to a public invitation posted on a popular social media platform. They participated in a semi-structured online interview during which they were invited to talk about their experience of the lock-down in relation to their role as working mothers. The interviews were transcribed and analyzed using the Interpretive Phenomenological Analysis (IPA). A common theme that emerged from their stories was the experience of loss of control over their lives and possibly a loss of the multiple dimensions of their identity, which appeared to have been reduced to being just a mom. Gender and parenting ideologies present prior to the pandemic continue to affect working mothers’ experiences during the pandemic.
Evaluation of the Effect of Topically Applied Probiotics on Interleukin-10 and Osteoprotegerin as an Adjunctive Treatment of Stage І and П Grade A Periodontitis Cases

Aim: the use of probiotic gel may be considered as beneficial treatment for periodontitis. This study was directed to evaluate the possible effect of topically applied probiotics on Interleukin-10 (IL-10) and osteoprotegerin (OPG) combined with scaling and root planning (SRP) in treatment of stage І and П grade A periodontitis. Subjects and Methods: 18 female patients were divided randomly into two equal groups. Group I (PG): received SRP combined with topically applied probiotics gel. Group II(CG): received SRP only. All patients were received phase I periodontal therapy. Then all patients were evaluated clinically and biochemically at base line, one month and three months after periodontal therapy Results recorded, tabulated and statistically analyzed using SPSS (statistical package for social sciences). Results: Clinical parameters such as plaque index (PI), gingival index (GI), probing pocket depth (PPD) and clinical attachment level (CAL) were evaluated. In all groups there was a significant reduction regarding the clinical parameters. There was insignificant better results regarding PI and GI in group I. while, there was significant better results regarding PPD and CAL in group I than group II. OPG levels showed insignificant better results in PG than CG but IL-10 levels showed significant better results in PG over time than CG. Conclusion: Adjunctive topically applied probiotic gel exhibited anti inflammatory effect through the significant expression of IL-10 after treatment of stage I and II grade A periodontitis patients. On the other hand seemed to be non significantly improve the bone formation through the limited expression of OPG
A Cadaveric Evaluation of Hypertrophic Obstructive Cardiomyopathy

Hypertrophic obstructive cardiomyopathy (HOCM) describes a pathologic state in which the subaortic region of the interventricular septum undergoes significant hypertrophy and fibrosis, resulting in septal bowing into the left ventricle. The reduced left ventricular chamber size and altered cardiac function impair diastolic filling, stroke volume, and cardiac output. This case report evaluates the cardiac tissue of a 36-year-old, formalin-embalmed cadaver affected by HOCM, with the goal of providing a comprehensive overview of the gross and pathologic findings associated with the condition. This donor’s heart was found to be larger than average, weighing 510.1 g, which is 52% heavier than the predicted value of 335.6 g for a male of similar stature. The thickness of the interventricular septum, right ventricular free wall, and left ventricular free wall was comparable to other reports of HOCM. However, asymmetrical thickening of the left ventricular walls, which is characteristic of HOCM, was less prominent than expected. Histologic staining of the cadaveric tissue, with hematoxylin and eosin, trichrome, and desmin, further bolstered the diagnosis. Importantly, this also showed that histologic examination of embalmed tissue is effective and diagnostic, even 11 months after embalming. The report herein demonstrates that morphologic and histologic analysis of cadaveric cardiac tissue is sufficient to support a diagnosis of HOCM. To the researchers' knowledge, this is the first case report evaluating HOCM in a cadaver donated for medical education.
Toward the Understanding of Religious Orientation and Market
Mavenism: Establishing a Correlation Relationship

This study argues that religious orientation may have a firm association with market mavenism. A positive association between religious orientation (Intrinsic & Extrinsic) and a market maven was hypothesized. A revision religious Scale of the Worldwide- I-E (Gorsuch & McPherson, 1989) was used to measure the variables of religiosity, and Feick and Price’s (1987) 6-item scale was used to measure the extent of market mavenism. The Pearson product moment coefficient of correlation was calculated to assess the relationship between religiosity and being a market maven. The results revealed a significant positive relationship between intrinsic religious orientation and being a market maven. Results attested that there is a significant relationship between extrinsic religious orientation with positive direction (social and personal) and being a market maven. The main contribution of this study is that, to the best of the writer's understanding, this is the first study to explore the relationship between religiosity and market maven.
MRI enhances the understanding of critical anatomy during primary laparoscopic port placement

Despite the majority of laparoscopic visceral injuries occurring with primary entry, high-fidelity training models are lacking. Three healthy volunteers underwent non-contrast 3T MRI at Edinburgh Imaging. A direct entry 12mm trocar was filled with water to improve MR visibility, placed on the skin at entry points, then images were acquired in the supine position. Composite images were created, and distances from the trocar tip to the viscera were measured, demonstrating anatomical relationships during laparoscopic entry. With a BMI of 21 kg/m2, gentle downward pressure during skin incision or trocar entry reduced the distance to the aorta to less than the length of a No. 11 Scalpel blade (22mm). The need for counter-traction and stabilisation of the abdominal wall during incision and entry is demonstrated. With a BMI of 38 kg/m2, deviating from the vertical angle for trocar insertion can result in the entire trocar shaft being placed within the abdominal wall without entering the peritoneum, creating a ‘failed entry. ’ At Palmer’s point distance between the skin and bowel is only 20mm. Ensuring the stomach is not distended will minimise gastric injury risk. The use of MRI to provide visualisation of the critical anatomy during primary port entry allows the surgeon to gain better understanding of textually described best practice techniques.
A note in approximative compactness and continuity of metric projections in Banach spaces

We give a counterexample to a recent statement in the metric approximation theory and provide a setting where the statement holds. Let (X;k k ) be a real Banach space. Our notation is standard. We follow, for example, [FHHMPZ01]. In this note, if no reference to a dierent topology on
