THE FATE OF DEAD RADIO-LOUD ACTIVE GALACTIC NUCLEI: A NEW PREDICTION OF LONG-LIVED SHELL EMISSION

We examine the fate of a dead radio source in which jet injection from the central engine has stopped at an early stage of its evolution ( t = t j ≲ 10 5 years ? > ). To this aim, we theoretically evaluate the evolution of the emission from both the lobe and the shell, which are composed of shocked jet matter and a shocked ambient medium (i.e., shell), respectively. Based on a simple dynamical model of expanding lobe and shell, we clarify how the broadband spectrum of each component evolves before and after the cessation of the jet activity. It is shown that the spectrum is strongly dominated by the lobe emission while the jet is active ( t ≤ t j ? > ). On the other hand, once the jet activity has ceased ( t > t j ? > ), the lobe emission fades out rapidly, since fresh electrons are no longer supplied from the jet. Meanwhile, shell emission only shows a gradual decrease, since fresh electrons are continuously supplied from the bow shock that is propagating into the ambient medium. As a result, overall emission from the shell overwhelms that from the lobe at a wide range of frequencies from radio up to gamma-ray soon after the jet activity has ceased. Our result predicts a new class of dead radio sources that are dominated by shell emission. We suggest that the emission from the shell can be probed in particular at radio wavelengths with the Square Kilometer Array phase 1.
INFLUENCE OF NITRATE AND AMMONIUM NITROGEN SOURCES ON GROWTH, NUTRIENT UPTAKE AND PHOTOSYNTHETIC ACTIVITY OF LUPIN (Lupinus albus L. var termis Forsk

A water culture experiment was carried out on lupin plants, to study the influence of different nitrate and ammonium ratios on growth, nutrient uptake and photosynthesis process, in respect of chlorophyll content and carbonic anhydrase activity (CAA). Nitrogen was applied in five NO 3 /NH 4 ratios : (100 : 00 ), (75 : 25) ,(50 : 50 ), (25 : 75) and (00:100). Results revealed that both shoots and roots dry weights wwere significantly increased as the portion of NO 3 in the growth medium increased. Also P and Mg concentrations in the shoots were increased with increasing NO 3 . While, K and Ca in the shoots and K in the roots were increased with increasing NH 4 level. 75% of applied N in NH 4 form caused a decrease in Zn and Cu concentrations in the shoots. In contrast, Fe increased and no specific trend was observed for Zn , Fe and Cu in the roots. P uptake by shoots was not significantly affected, while P uptake by roots was significantly affected. Highest K uptake in shoots and roots was observed when NO 3 was the sole nitrogen source. Ca uptake by shoots and roots significantly increased when portion of NH 4 increased. Zn, Fe and Cu uptake by roots were increased significantly, when NH 4 portion increased. In addition, Zn and Cu uptake by shoots of lupin plants were increased significantly when plants were fed with nitrogen all in NO 3 from. Chl. a and Chl. ( a + b) showed the highest value when NO 3 was the sole source for nitrogen, except Chl b. which showed the maximum value when NO 3 was only 25% from applied nitrogen. In addition, CAA was significantly increased when 100% NO 3 was used in the growth root medium.
INFLUENCE OF NITROGEN FERTILIZER ON SOME QUALITY, TECHNOLOGICAL ASPECTS, PRODUCTIVITY AND AMINO ACIDS ACCUMULATION OF SUGAR BEET

Two field trials were conducted in 1998/99 and 1999/2000 seasons in Kafr El-Sheikh governorate to study the effect of various nitrogen rates i.e.60, 80, 100, 120, 140, and 160% of the recommended rate (RR) (RR=75kg N/fed) on root quality, technological parameters and yield of sugar beet. Analysis of variance revealed that: Increasing N dressing up to 90 kg N/ fed (20% over RR) exhibited the highest root quality, technological parameters, root and sugar yield ton / fed and minimized sugar lost to molasses. On the other hand, further N dressing decreased markedly the most studied traits. Nitrogen dressing enhanced the content of N, P, K and Na, where a significant improvement in the concentration of those elements in samples of beet leaves and roots aged 90 and 150 days from sowing. Accumulation of 16 amino-acids % tended to increase in beet root at harvest as nitrogen rate increased. Glutamic acid was in an abnormally high concentration under various nitrogen rates followed by Aspartic acid and the remaining acids were found in relatively low concentration. It could be recommended, under the condition of this work, increasing N dressing up to 90 kg /fed (20% over RR) to maximize root and sugar yield
Graph Mining and Community Evaluation with Degeneracy

The study and analysis of social networks attract attention from a variety of Sciences (psychology, statistics, sociology). Among them, the field of Data Mining offers tools to automatically extract useful information on properties of those networks. More specifically, Graph Mining serves the need to model and investigate social networks especially in the case of large communities - usually found in online media - where social networks are prohibitively large for non-automated methodologies. The general modeling of a social network is based on graph structures. Nodes of the graph represent individuals and edges signify different actions or types of social connections between them. A community is defined as a subgraph (of a social network) and is characterized by dense connections. Various measures have been proposed to evaluate different quality aspects of such communities - in most cases ignoring various properties of the connections (e.g. directionality). In the work presented here, the k-core concept is used as a means to evaluate communities and extract information. The k-core structure essentially measures the robustness of an undirected network through degeneracy. Further more extensions of degeneracy are introduced to networks that their edges offer more information than the undirected type. Starting point is the exploration of properties that can be extracted from undirected graphs (of social networks). On this, degeneracy is used to evaluate collaboration features - a property not captured by the single node metrics or by the established community evaluation metrics - of both individuals and the entire community. Next, this process is extended for weighted, directed and signed graphs offering a plethora of novel evaluation metrics for social networks. These new features offer measurement tools for collaboration in social networks where we can assign a weight or a direction to a connection and provide alternative ways to signify the importance of individuals within a community. For signed graphs the extension of degeneracy offers additional metrics that can be used for trust management. Moreover, a clustering approach is introduced which capitalizes on processing the graph in a hierarchical manner provided by its core expansion sequence, an ordered partition of the graph into different levels according to the k-core decomposition The graph theoretical models are then applied in real world graphs to investigate trends and behaviors. The datasets explored include scientific collaboration and citation graphs (DBLP and ARXIV), a snapshot of Wikipedia's inner graph and trust networks (e.g. Epinions and Slashdot). The findings on these datasets are interesting and the proposed models offer intuitive results.
Assessment of Women Satisfaction with Pregnancy Outcome and Using of Immediate Contraceptive Postnatal at Baghdad Maternity Hospitals

Back ground: Contraceptive following delivery or an induced abortion reduces the risk of an early unintended pregnancy and it's associated to adverse health consequences The Study aims to assess the women satisfaction in the use of contraceptive devices in the period immediately following delivery or abortion and it's relation to pregnancy outcome. Patients and Methodology: A randomized cross sectional descriptive study carried out In 2 maternity hospitals (AL-Elwiya maternity teaching hospital, AL-Karkh maternity hospital) from both sides of Baghdad. The study sample includes 434 cases of women who were in the labor and abortion wards in the period immediately following delivery or abortion before being discharged home. Data were collected during the period from the 1st of November 2015 to the end of April 2016. Results: revealed that more than half (54.4%) of studied women were married in young age group (18-24 years) and 48.6% of them were at young age (18-24 years) at their first delivery, 36.4% were graduated from university, (90.3%) were living in urban areas . The pregnancy ended with delivery in 65.2% of the studied women and ended with miscarriage in 34.8% of them. A significant association was observed between young age of women and high satisfaction with immediate contraception (p=0.02). The most common cause of non-satisfaction with contraception among studied women was not knowing about the possibility of contraception (97.67%), followed by their wish to increase their family size (39.5%), fear from complications (23.2%), economic causes (18.6%), un cooperation of the family (13.9%), bad effect on breast feeding (9.3%) and unavailability (6.9%). one third (31.1%) of the participants were satisfied with immediate contraception while it is about half (49.1%) of the delivered mothers were satisfied on immediate contraceptive with significant difference found between pregnancy outcome and the women's satisfaction. Conclusion: 49.1% of the mothers were satisfied on immediate contraception after delivery while only 31.1% of the miscarried women were satisfied with immediate contraception. Women from low income families had higher satisfaction with contraception and significant association was found between types of pregnancy outcome and women satisfaction with immediate use of contraceptive devices.

Asymptotic normalization coefficients from ab initio calculations

We present calculations of asymptotic normalization coefficients (ANCs) for one-nucleon removals from nuclear states of mass numbers 3 {le} A {le} 9. Our ANCs were computed from variational Monte Carlo solutions to the many-body Schroedinger equation with the combined Argonne v{sub 18} two-nucleon and Urbana IX three-nucleon potentials. Instead of computing explicit overlap integrals, we applied a Green function method that is insensitive to the difficulties of constructing and Monte Carlo sampling the long-range tails of the variational wave functions. This method also allows computation of the ANC at the physical separation energy, even when it differs from the separation energy for the Hamiltonian. We compare our results, which for most nuclei are the first ab initio calculations of ANCs, with existing experimental and theoretical results and discuss further possible applications of the technique.
The final phase of inspiral of strange quark star binaries

We present calculations of the final phase of inspiral of irrotational strange star binaries. Two types of equation of state at zero temperature are used - the MIT bag model and the Dey et al. 1998 model of strange quark matter. We study the precoalescence stage within the Isenberg-Wilson-Mathews approximation of General Relativity using a multidomain spectral method. The gravitational-radiation driven evolution of the binary system is approximated by a sequence of quasi-equilibrium configurations at a fixed baryon number and with decreasing separation. We find that the innermost stable circular orbit (ISCO) is determined always by an orbital instability for binaries consisting of two stars built predominantly of strange quark matter independently on the total mass of a binary system and compactness parameter of each star. In contrast, for neutron stars described by baryonic equation of state without exotic phases the ISCO is given by the mass-shedding limit. The gravitational wave frequency at the ISCO, which marks the end of the inspiral phase, is always higher than 1.1kHz for equal masses irrotational strange quark stars with the total mass-energy of a binary system greater than $2 M_\odot$. We find that the dependence of the frequency of gravitational waves at the ISCO on the compactness parameter for the equal mass binaries can be described by the same simple analytical formulae for broad ranges of masses independently on a strange star model. Detailed comparisons with binary neutrons star models, as well as with the third order Post-Newtonian point-mass binaries are given. The difference in the phase, for two $1.35 M_\odot$ strange stars, between our numerical results and 3PN is $\sim 40 \%$ for the last two orbits of inspiral.
Properties of the operator product expansion in quantum field theory

We prove that the operator product expansion (OPE), which is usually thought of as an asymptotic short distance expansion, actually converges at arbitrary finite distances within perturbative quantum field theory. The result is derived for the massive scalar field with $\varphi^{4}$-interaction on Euclidean spacetime. This constitutes a generalisation of an earlier result by Hollands and Kopper, which states that the OPE of exactly two quantum fields converges. We also show that the OPE coefficients satisfy factorisation conditions for certain configurations of the spacetime arguments. Such conditions are known to encode information on the algebraic structure of the underlying quantum field theory. Both results rely on modified versions of the renormalisation group flow equations, which allow us to derive explicit bounds on the remainder of these expansions. Within this framework, we also derive a new formula for the perturbation of OPE coefficients, i.e. an equation relating coefficients at a given perturbation order to those of lower order. By iteration of this formula, a new constructive method for the computation of OPE coefficients in perturbation theory is obtained, which only requires the coefficients of the free theory as initial data. Finally, we investigate a strategy to restrict renormalisation ambiguities in quantum field theory via the condition that the OPE coefficients depend analytically on the coupling constant(s) of the respective model. We apply this strategy to the computation of the vacuum expectation value of the stress energy operator in the two dimensional Gross-Neveu model and we obtain a unique prediction for the non-perturbative contribution to this expectation value, which is of the order $\exp(-2\pi/g^{2})$ (here $g$ is the coupling constant). We discuss the possibility that a similar effect, if present in the Standard Model of particle physics, could account for the ''unnatural'' smallness of the cosmological constant.
Menstrual hygiene management practices among secondary school girls in Ifakara Town, Kilombero District, Tanzania

Background: In developing countries many adolescent girls lack appropriate information, materials and access to the right sanitary facilities to manage menstruation. Therefore, this study aimed to assess menstrual hygiene management practices among secondary school girls in Ifakara Town, Kilombero District, Tanzania. Methods: A school based cross-sectional study was conducted from April to June 2021 among secondary school girls Ifakara Town, Kilombero District, Tanzania. A total of 138 girls were selected randomly and interviewed using a structured questionnaire. Results: Overall, 67.4% of the girls had good knowledge on menstrual hygiene management practices. Out of these, 94.2% used commercial disposable sanitary pads as absorbents, 92.7% Changed pads more than three times a day during menstruation, 96.4% Cleaned external genitalia with soap and water during menstruation. Conclusion: In this study, the practice of menstrual hygiene management of secondary school girls was good. This highlights the need of education on menstrual hygiene management to all secondary school girls country wide.
COMPARISON AMONG THE EFFECTS OF CLOVER HAY AND CORN SILAGES AS FEED INGREDIENTS ON PERFORMANCE OF LACTATING GOATS

The effects of clover hay (CH), corn silage with ears (CS) and corn silage without ears (S) as roughage ingredients of lactating goats on their performance for milk yield and composition were investigated. Eighteen female Zaraibi goats in the 3 rd season of lactation with average body weight of 38 Kg were divided randomly into three equal groups. All groups fed on restricted amount of concentrate feed mixture (CFM) and bean straw (BS) (800 and 300 g/h/d, respectively) along with CH, CS and S ( ad lib. ) in group 1 (control), 2 and 3, respectively. Average daily milk yield of goats fed CH or CS diets (0.769, 0.798 Kg, respectively) were higher (P<0.01) than those fed S diet (0.650 Kg). Milk fat % was not significantly affected by the treatments, but protein, lactose and total solids % were significantly (P<0.05) higher of goats fed CS than those fed CH or S diets. On the other hand, the average milk protein and solids non fat (g/h/d) were significantly higher (P<0.01) of goats fed CS than those fed CH or S diets. The milk lactose (g/h/d) was significantly (P<0.05) higher of goats fed CS than those fed CH or S diets. The fat corrected milk (4% FCM) and energy corrected milk (Kg/h/d) were significantly higher (P<0.05) of goats fed CH or CS than those fed S diets. Total DM intake as Kg/h/d was increased when feeding on CH followed by that feeding on S diets. Economic efficiency data showed that the CS ration was economically superior to the CH, followed by that containing S diets. FCM differed according to forage source being fed. Yield of FCM was greatest for goats fed CH or CS than S diets.
EFFECT OF DUAL BIOFERTILIZATION, BIOGAS MANURE AND MINERAL FERTILIZER ON GUAR PLANTS [Cyamopsis tetragonoloba (L.) TAUB.]

Two field experiments were conducted in June 1997 and 1998 to study the effect of dual inoculation with Rhizobium as symbiotic N 2 -fixer and Azospirillum lipoferum as asymbiotic N 2 -fixer, biogas manure and mineral fertilizer on nodulation, N 2 -ase activity and yield of guar plants [ Cyamopsis tetragonoloba ( L.) Taub. ] Investigation results showed that, guar seeds application with dual inoculation of Rhizobium and Azospirillum lipoferum and provided with half dose of biogas manure (20 kg N/fed), gave the highest values of bacterial densities in soil rhizosphere, CO 2 evolution, N 2 -ase activity, nodulation and guar seed contents of total carbohydrates and guar gum. Dual inoculation combined with half dose of inorganic nitrogen or half dose of organic nitrogen (20 kg N/fed) increased all values than combination with full dose (40 kg N/fed) of each inorganic nitrogen or organic nitrogen fertilizers. Also, individual Rhizobium inoculation supplied with 40 kg N/fed organic nitrogen or inorganic nitrogen increased the values of all treatments than individual inoculation with dual inoculation received the full dose of organic or inorganic nitrogen.
Symplectic nonsqueezing of the KdV flow

We prove two finite dimensional approximation results and a symplectic non-squeezing property for the Korteweg-de Vries (KdV) flow on the circle T. The nonsqueezing result relies on the aforementioned approximations and the finite-dimensional nonsqueezing theorem of Gromov. Unlike the work of Kuksin which initiated the investigation of non-squeezing results for infinite dimensional Hamiltonian systems, the nonsqueezing argument here does not construct a capacity directly. In this way our results are similar to those obtained for the NLS flow by Bourgain. A major difficulty here though is the lack of any sort of smoothing estimate which would allow us to easily approximate the infinite dimensional KdV flow by a finite-dimensional Hamiltonian flow. To resolve this problem we invert the Miura transform and work on the level of the modified KdV (mKdV) equation, for which smoothing estimates can be established.
Prevalence of COVID-19 associated cytokine storm in diabetic versus non diabetic patients

a novel coronavirus, the so-called severe acute Abstract Introduction: COVID-19, a global pandemic has created a worldwide disaster since its first outbreak in December 2019 in Wuhan, China. Diabetic patients with COVID-19 have a worse prognosis and increased mortality. Cytokine storm is an aggressive inflammatory response to the SARS-CoV-2 virus and is associated with lung damage, multiple organ failure, and a bad COVID-19 prognosis. Aim of the study: The study aimed to evaluate the levels of some cytokine storm parameters in COVID-19 infection, besides a comparison of these levels between diabetic and nondiabetic Egyptian patients. Subjects and Methods: the current cross-sectional study recruited 80 adult individuals. All patients were divided into two groups: 42 diabetic patients with COVID-19 and 38 nondiabetic patients with COVID-19. Patients with diseases of inappropriate cytokine inflammatory load, such as autoimmune diseases or malignancies, were excluded. The medical history and clinical examination were performed. The cytokine storm inflammatory markers, such as C-reactive protein (CRP), Ferritin, Lactate dehydrogenase (LDH), D-dimer, Neutrophil-Lymphocyte Ratio (NLR), and Interleukine-6 (IL-6) were tested, in addition to the examination of the Glycemic state: HBA1C, FBS, and 2HPP. Duration of hospital admission and mode of respiratory support were recorded. Results: The results showed that 61% of diabetic patients needed more intensive care unit (ICU) admission than 36.8% of non-diabetics (P=0.025). The mean serum level of IL-6 was 126.55 ± 45.65 pg/ml in diabetic patients compared to 99.58 ± 52.77 pg/ml in non-diabetic, which was statistically significant (P=0.033). The ROC curve analysis showed that IL-6 was a significant marker of mortality (P<0.001) with a cut-off level >136 pg/mL at 95.65% sensitivity and 87.72% specificity. Furthermore, HBA1C was a significant marker of mortality (P<0.001) with a cut-off value >7.8 % at a sensitivity of 65.22 % and specificity of 63.16 %. Conclusion: Our study confirmed that diabetic patients had significantly earlier onset of cytokine storm, higher inflammatory response, longer hospital admission duration, higher admission rate to ICU, and more need for mechanical ventilation compared to non-diabetics.
