Evolutions and Calibrations of Long Gamma-Ray-burst Luminosity Correlations Revisited

Luminosity correlations of long gamma-ray bursts (GRBs) are extensively proposed as an effective complementarity to trace the Hubble diagram of the universe at high redshifts, which is of great importance to explore properties of dark energy. Recently, several empirical luminosity correlations have been statistically proposed from GRB observations. However, to treat a GRB as the distance indicator, there are two key issues: the redshift evolution of luminosity correlations and their calibrations. In this paper, we choose the Amati relation, the correlation between the peak spectra energy and the equivalent isotropic energy of GRBs ( E p – E iso ) as an example and find that the current GRB data set implies that there could be a evolution of the luminosity correlation with respect to the redshift. Therefore, we propose an extended Amati relation with two extra redshift-dependent terms to correct the redshift evolution of the GRB relation. Second, we carefully check the reliability of the calibration method using the low-redshift GRB data. Importantly, we find that the low-redshift calibration method does not take whole correlations between Ω m and coefficients into account. Neglecting this correlation information can break the degeneracies and obtain the biased constraint on Ω m , which is very sensitive to values of parameters for the calibration. A small shift in the parameters of the “calibrated” relation could significantly change the final constraint on Ω m in the low-redshift calibration method. Finally, we simulate several GRB samples with different statistical errors and find that, in order to correctly recover the fiducial value of Ω m , using the low-redshift calibration method, we need a large number of GRB samples with high precisions.
RAPD Markers are Associated with Self-incompatibility Characteristics as Related to the Number of Seeds per Fruit of Some Mandarin and Clementine Cultivars

(Received 10/08/2022, accepted 20/09/2022) DOI: 10.21608/EJOH.2022. 155513.1206 ©2022 National Information and Documentation Centre (NIDOC) THE experiments were performed using (Nour, Fedela, Spinosa clementines, Kishu seedless, Balady, and Seedless mandarins) to determine the compatibility or incompatibility as related to the number of seeds per fruit and the genetic relation between them. For two consecutive seasons (2020 and 2021), the growth of the pollen tube in the styles following self-pollination has been analyzed using a fluorescence microscope to detect incompatibility properties. According to Nour and Fedela clementine cultivars are highly incompatible, while the other four cultivars are incompatible. After receiving pollen, Nour and Fedela clementines had very low pollen tubes that reached style. On the other hand, the highest rate was in the other four cultivars. The DNA of the six cultivars of mandarin and clementine investigated in this study was very similar. Balady mandarin and seedless mandarin appear to have very high similarities, while Fedela clementine and seedless mandarin appear to be very low. RAPD-PCR showed a specific molecule related to incompatibility such as (A-18) RAPD primer, at MW 361 bp. linked to the incompatibility of Nour and Fedela clementine c.vs.
Biological control of two pathogenic fungi by silicate bacteria

Silicate solubilizing bacteria (SSB) play a critical role in soil fertility by utilizing available forms of silicates minerals. Furthermore, SSB can also enhance plant defense mechanisms. Distribution of rhizobacteria in fields had been cultivated with flax and wheat which, are high silicate accumulators, and screened for available silicate on a selective medium, the bacterial counts varied markedly with a type of plantation in soil. Four bacterial strains were capable of solubilizing biotite (source of silicate mineral): Pseudomonas fluorescens , Bacillus subtilis , Proteus mirabilis, and Bacillus circulans . By using dual culture antagonistic assays were carried out on these bacteria versus two pathogens fungi ( Fusarium oxysporum and Rhizoctonia solani ) . The inhibition zone of these bacteria against two pathogenic fungi ranged 10 to 33 mm. The maximum inhibition zone by bacterial strains was shown by the strain B. subtilis followed by Ps. fluorescens. When detected the antagonistic metabolites, siderophores were produced by Ps. fluorescens and B. subtilis also these two strains with B. criculans produced chitinase. Only Proteus mirabilis produced hydrogen cyanide. The SSB strains showed different levels of efficiency in increasing the survival of flax seedlings however, two bacterial strains ( B. subtilis & Ps. fluorescens) showed maximum efficiency under glasshouse conditions compared with the control. Finally, the strong action of silicate bacteria is very important in the development of bio fungicides against fungal pathogens.
Efficacy of Epidural Analgesia During Labour

Although labour is considered as a normal physiological process, it can produce significant pain, requiring appropriate pain management. A painful labour also had detrimental effects on the mother and fetus. Ideal labour analgesia technique should dramatically reduce the pain of labour, while allowing the parturient to actively participate in birthing experience and have minimal adverse effects on the fetus and progress of labour. Epidural analgesia and opioids are often used for management of labour pain. Epidural analgesia is an effective method for managing labour pain. Studies have indicated that the procedure has few contraindications and few side-effects. The study was done to see the efficacy and safety of epidural analgesia with conventional analgesia (Inj. Pethidine and phenergan) during labour. In this study, pregnant women with active labour (Cervical dilation 4cm) were grouped into two A & B. Group A received epidural analgesia (0.125% Bupivacaine & 50 microgram Fentanyl) & group B received conventional analgesia (Inj. Pethidine & phenergan). Then the subjects were followed up and outcomes were recorded in a preformed data collection sheet. All data were analyzed by computer based software SPSS version 15. The study demonstrated a significantly earlier onset of effective analgesia in epidural group than that in the conventional group. The pain score at onset of analgesia and at different time intervals following induction and at the time of delivery were appreciably lower in women receiving epidural analgesia than those receiving conventional analgesia (p<0.001). There was no significant difference between epidural and conventional groups in terms of complications like nausea and/or vomiting (p=0.431), prolonged 2nd stage of labour (p=0.127), mode of delivery (Normal / Instrumental / Cesarean) (p=0.455). Neonatal outcome was evaluated in terms of APGAR score at 1& 5 minutes of birth in both groups which showed no significant differences (p=0.401and p=0.536 respectively). So, epidural analgesia is an effective analgesia during labour. JCMCTA 2016 ; 27 (2) : 12 - 17
Infrared Photometry of NGC 6791

We present deep JHK photometry of the old and metal-rich open cluster NGC 6791. The photometry reaches below the main-sequence turnoff to K ≈ 16.5 mag. We combine our photometry with that from Stetson et al. to provide color-magnitude diagrams showing K versus J - K, K versus V - K, and V versus V - K. We study the slope of the red giant branch in the infrared but find that it is not a useful metallicity indicator for the cluster, nor any metal-rich cluster that lacks a well-populated red giant branch, because it is not linear, as has often been assumed, in K versus J - K. The mean color of the red horizontal-branch/red clump stars provide an estimate of the cluster reddening, E(B - V) = 0.14 ± 0.04 mag for [Fe/H] = +0.4 ± 0.1. The mean magnitudes of these stars also provide a good distance estimate, (m - M)0 = 13.07 ± 0.04. Finally, we find that the isochrones of Yi et al. provide optimal fits in V versus B - V and V - K and K versus J - K and V - K for such values if [Fe/H] lies between +0.3 and +0.5 (with a slight preference for +0.5) and ages between 9 Gyr ([Fe/H] = +0.3) and 7.5 Gyr ([Fe/H] = +0.5).
The XXL Survey

We present results from a 100 ks XMM-Newton observation of galaxy cluster XLSSC 122, the first massive cluster discovered through its X-ray emission at z ≈ 2. The data provide the first precise constraints on the bulk thermodynamic properties of such a distant cluster, as well as an X-ray spectroscopic confirmation of its redshift. We measure an average temperature of kT = 5.0 ± 0.7 keV; a metallicity with respect to solar of Z/Z⊙ = 0.33−0.17+0.19, consistent with lower-redshift clusters; and a redshift of z = 1.99+0.07-0.06 , consistent with the earlier photo-z estimate. The measured gas density profile leads to a mass estimate at r500 of M500 = (6.3 ± 1.5) × 1013 M⊙. From CARMA 30 GHz data, we measure the spherically integrated Compton parameter within r500 to be Y 500 = (3.6 ± 0.4) × 10−12. We compare the measured properties of XLSSC 122 to lower-redshift cluster samples, and find good agreement when assuming the simplest (self-similar) form for the evolution of cluster scaling relations. While a single cluster provides limited information, this result suggests that the evolution of the intracluster medium in the most massive, well-developed clusters is remarkably simple, even out to the highest redshifts where they have been found. At the same time, our data reaffirm the previously reported spatial offset between the centres of the X-ray and SZ signals for XLSSC 122, suggesting a disturbed configuration. Higher spatial resolution data could thus provide greater insights into the internal dynamics of this system.
Filed Studies on The most Prevailing Bacterial Diseases Affecting Some Cultured Marine Fishes Egypt

T HE objective of this study was recorded the most prevailing bacterial agents which spreads in the cultured fish in Ismailia province, Eastern Egypt. This study was carried out on 1080 premature fish. 360 Dicentrarchus labrax (225±25 g) and 360 Sparus aurata (150±25 g), and 360 Mugil cephalus (125±25). The examined fishes showed exophthalmia, hemorrhagic area on the skin, around the buccal cavity, head, and on the base of the fines, ulcers varied in their degrees, dark colour, and respiratory signs. The recorded postmortem lesions were septicemic signs with enlargement and congestion of the liver and spleen with distended gall bladder. With the presence of serous to hemorrhagic ascetic fluid, the stomach and intestines displayed congestion, thickening, and inflammation of their walls. The total prevalence of bacterial infection in examined premature fishes was 27.68%. The highest percentage was in D. labrax at 38.88%, followed by S. aurata at 27.22%, and the lowest percentage in M. cephalus at 16.94%. The most prevailing bacterial agents were Vibrio spp and Pseudomonas spp.
Evidence for Unconventional Superconductivity in Arsenic-Free Iron-Based Superconductor FeSe: A 77Se-NMR Study

We report the results of 77 Se-nuclear magnetic resonance (NMR) in α-FeSe, which exhibits a similar crystal structure to the LaFeAsO 1- x F x superconductor and shows superconductivity at 8 K. The nuclear-spin lattice relaxation rate 1/ T 1 shows T 3 behavior below the superconducting transition temperature T c without a coherence peak. The T 1 T = const. behavior, indicative of the Fermi liquid state, can be seen in a wide temperature range above T c . The superconductivity in α-FeSe is also an unconventional one as well as LaFeAsO 1- x F x and related materials. The FeAs layer is not essential for the occurrence of the unconventional superconductivity.
MOLECULAR INVESTIGATION OF SOME BACTERIA (COXİELLA BURNETİİ, MYCOPLASMA HAEMOCANİS, CANDİDATUS MYCOPLASMA HAEMATOPARVUM, WOLBACHİA) IN RHIPICEPHALUS SANGUINEUS TICKS IN SIIRT PROVINCE, TURKEY

Ticks harbor the largest diversity of microorganisms, ranging from viruses, prokaryotes, and eukaryotes. Rhipicephalus sanguineus ticks are the most common ticks worldwide. Although dogs are the main host of this tick species, it has been reported that it also infests humans in various parts of the world. This study aimed to examine some bacteria ( Coxiella burnetii , Mycoplasma haemocanis, Candidatus Mycoplasma haematoparvum, Wolbachia) in Rhipicephalus sanguineus ticks sampled from dogs. In this study, 350 tick samples collected from 85 dogs in Siirt province were determined to be Rhipicephalus sanguineus ticks. Coxiella DNA was detected in 3 (0.85%) out of 350 ticks using Nested PCR (687 base pairs). None of the samples were found to contain Mycoplasma haemocanis , Candidatus Mycoplasma haematoparvum, and Wolbachia DNA. A partial sequence of the IS 1111 gene region was registered in GenBank with OM472143 accession numbers. Considering the zoonotic nature of the Q disease, it is very important for dog owners and related institutions to periodically spray animals against ticks, and to take any other necessary precautions. More samples are needed to determine the Mhc, CMhp, and Wolbachia prevalence.

Case Report of Disseminated Adrenal Histoplasmosis and Secondary Adrenal Insufficiency

Histoplasmosis is a chronic, infectious disease caused by the environmental fungus H. capsulatum, primarily affecting the respiratory system. In immunocompromised patients, histoplasmosis can become severely complicated due to dissemination into various other organ systems. Adrenal insufficiency is an uncommon complication of disseminated histoplasmosis, as its manifestation requires necrotizing granulomatous inflammation of both adrenal glands. We describe a rare case of delayed histoplasmosis in the bilateral adrenal glands and liver of an immunocompromised patient with development of symptoms at 21 years after liver transplant and nine years after renal transplant. In addition, this patient presented with secondary adrenal insufficiency due to long-term use of corticosteroids rather than the typical primary adrenal insufficiency seen in histoplasmosis with adrenal involvement.
Impact of Foliar Application of Calcium Nitrate and Chelated Calcium in Combination with Boric Acid on the Vegetative Growth, Yield, Quality Components and Insect Control of Globe Artichoke

This study was conducted to investigate the impact of foliar application calcium nitrate and chelated calcium in three levels (0, 380 and 760 ppm as Ca) in combination with boric acid (85 ppm as B) on the growth, yield, quality, and insect control of globe artichoke cv. Herous in the 2019/2020 and 2020/2021seasons at EL-Qanater Research Station Farm in Qalubia Governorate. The experimental design was a complete randomized block with three replicates. Results showed that foliar spraying of calcium nitrate at 760 ppm or chelated calcium at 380 and 760 ppm + boron (85 ppm) resulted in the highest values of vegetative growth, the physical characteristics of early, total yield and the highest head number of early yield. Moreover, spraying Ca NO 3 at (380 ppm) + B or both Ca-EDTA levels + B produced the maximum head number of total yield. The highest dry matter % and inulin content was achieved by spraying Ca NO 3 (760 ppm) + B or both Ca-EDTA levels + B. Spraying Ca-EDTA (380 ppm) + B achieved the highest values of total phenols and phosphorus %. Spraying both Ca NO 3 (760 ppm) + B produced the highest N and protein % as well as both Ca-EDTA levels + B produced the highest K, Ca, and B content of heads. It could be suggested that spraying Ca-EDTA at 380 and 760 ppm + boron at 85ppm were effective for enhancing artichoke production, improving its quality, and defending off three types of aphids.
Government at (Institutional) Work: The State and Market Dynamics

The state remains an undertheorized actor in studies of market change. Further, when the state's market-shaping activities are considered, they are generally characterized by notions of control over, or conflict with, market actors. In this project, we draw on theories of institutional change and management to develop and deploy an alternative perspective on state involvement in markets—one premised on collaboration. Using this conceptual framework, we examine how the state works to shape markets disrupted by ostensibly innovative entrants. Specifically, we examine the state's response to the market entry of transportation businesses Uber and Lyft, whose strategies of disregarding existing regulatory arrangements attempt to deliberately exclude the state from markets. Leveraging an institutional work perspective, we find the state engaging in four novel practices as it works to understand and shape market arrangements in conjunction with an array of interested market actors. We discuss the implications of this collaborative state behavior for studies of market change.
Two cylindrical vortex sheets : evolution and singularity formation

Using Rosenheads point-vortex approximation with correction terms, the evolution of two symmetrical, counter-rotating, initially cylindrical vortex sheets in an incompressible, potential uid ow is studied. Simulations are performed in time up to the occurrence of branch-point curvature singularities in the vortex sheetsgeometries. The numerical methods employed are discussed. Parameters pertaining to the asymptotics of the Fourier coe¢ cients of the vortex sheetspositions are numerically tted to gain insight into aspects of the singularity formation; these include the order of the branch-point singularities, and the times and locations of singularity formation. A smoothing over initial singularity formations is implemented by either the heat equation or through a local application of the vortex blob method in an attempt to gain details into further singularity formations. Lastly, the e¤ects of the initially prescribed total circulation around the vortex sheets on their evolutions are studied, both up to the time of singularity formation, and with the implementation of the vortex blob method, past the times of singularity formation.
Influence of Intellectual Capital on Company Value with Financial Performance as Intervening Variable

This study aims to analyze the effect of Intellectual Capital on firm value with financial performance as an intervening study variable in manufacturing companies listed on the Indonesia Stock Exchange (BEI) in 2015-2019. In this study, a sample of 375 companies using purposive sampling. In the first equation, there are 357 manufacturing company data companies. In the second equation, there are 352 manufacturing company data companies. The difference in the number of manufacturing company data used as the research sample is due to meeting the assumptions of the feasibility of the regression model in the first and second research models, so that outlier data in the first and second equations need to be eliminated. This study provides the results that Intellectual Capital has a significant positive effect on financial performance, financial performance has a significant positive effect on firm value, the effect of Intellectual Capital on firm value, Intellectual Capital has a positive and significant effect on firm value through financial performance as an intervening variable. ---------------------------------------------------------------------------------------------------------------------------------------Date
Magnetar Spin-Down, Hyperenergetic Supernovae, and Gamma-Ray Bursts

The Kelvin-Helmholtz cooling epoch, lasting tens of seconds after the birth of a neutron star in a successful core-collapse supernova, is accompanied by a neutrino-driven wind. For magnetar-strength (~1015 G) large-scale surface magnetic fields, this outflow is magnetically dominated during the entire cooling epoch. Because the strong magnetic field forces the wind to corotate with the proto-neutron star, this outflow can significantly affect the neutron star's early angular momentum evolution, as in analogous models of stellar winds. If the rotational energy is large in comparison with the supernova energy and the spin-down timescale is short with respect to the time required for the supernova shock wave to traverse the stellar progenitor, the energy extracted may modify the supernova shock dynamics significantly. This effect is capable of producing hyperenergetic supernovae and, in some cases, provides conditions favorable for gamma-ray bursts. We estimate spin-down timescales for magnetized, rotating proto-neutron stars and construct steady state models of neutrino-magnetocentrifugally driven winds. We find that if magnetars are born rapidly rotating, with initial spin periods (P) of ~1 ms, then of order 1051-1052 ergs of rotational energy can be extracted in ~10 s. If magnetars are born slowly rotating (P ≳ 10 ms), they can spin down to periods of ~1 s on the Kelvin-Helmholtz timescale.
