Predictions from non trivial Quark-Lepton complementarity

The complementarity between the quark and lepton mixing matrices is shown to provide robust predictions. We obtain these predictions by first showing that the matrix V_M, product of the quark (CKM) and lepton (PMNS) mixing matrices, may have a zero (1,3) entry which is favored by experimental data. We obtain that any theoretical model with a vanishing (1,3) entry of V_M that is in agreement with quark data, solar, and atmospheric mixing angle leads to $\theta_{13}^{PMNS}=(9{^{+1}_{-2}})^\circ$. This value is consistent with the present 90% CL experimental upper limit. We also investigate the prediction on the lepton phases. We show that the actual evidence, under the only assumption that the correlation matrix V_M product of CKM and PMNS has a zero in the entry (1,3), gives us a prediction for the three CP-violating invariants J, S_1, and S_2. A better determination of the lepton mixing angles will give stronger prediction for the CP-violating invariants in the lepton sector. These will be tested in the next generation experiments. Finally we compute the effect of non diagonal neutrino mass in "l_i -> l_j gamma" in SUSY theories with non trivial Quark-Lepton complementarity and a flavor symmetry. The Quark-Lepton complementarity and the flavor symmetry strongly constrain the theory and we obtain a clear prediction for the contribution to "mu -> e gamma" and the "tau" decays "tau -> e gamma" and "tau -> mu gamma". If the Dirac neutrino Yukawa couplings are degenerate but the low energy neutrino masses are not degenerate, then the lepton decays are related among them by the V_M entries. On the other hand, if the Dirac neutrino Yukawa couplings are hierarchical or the low energy neutrino masses are degenerate, then the prediction for the lepton decays comes from the CKM hierarchy.Comment: 15 pages, 5 figures, ws-ijmpa class included, Proceedings of the CTP Symposium on Sypersymmetry at LH

QQˉQ\bar Q (Q∈{b,c}Q\in \{b, c\}) spectroscopy using Cornell potential

The mass spectra and decay properties of heavy quarkonia are computed in nonrelativistic quark-antiquark Cornell potential model. We have employed the numerical solution of Schr\"odinger equation to obtain their mass spectra using only four parameters namely quark mass ($m_c$, $m_b$) and confinement strength ($A_{c\bar c}$, $A_{b\bar b}$). The spin hyperfine, spin-orbit and tensor components of the one gluon exchange interaction are computed perturbatively to determine the mass spectra of excited $S$, $P$, $D$ and $F$ states. Digamma, digluon and dilepton decays of these mesons are computed using the model parameters and numerical wave functions. The predicted spectroscopy and decay properties for quarkonia are found to be consistent with available experimental observations and results from other theoretical models. We also compute mass spectra and life time of the $B_c$ meson without additional parameters. The computed electromagnetic transition widths of heavy quarkonia and $B_c$ mesons are in tune with available experimental data and other theoretical approaches

Two Gallium data sets, spin flavour precession and KamLAND

We reexamine the possibility of a time modulation of the low energy solar neutrino flux which is suggested by the average decrease of the Ga data in line with our previous arguments. We perform two separate fits to the solar neutrino data, one corresponding to 'high' and the other to 'low' Ga data, associated with low and high solar activity respectively. We therefore consider an alternative to the conventional solar+KamLAND fitting, which allows one to explore the much wider range of the $\theta_{12}$ angle permitted by the KamLAND fitting alone. We find a solution with parameters $\Delta m^2_{21}=8.2\times 10^{-5} eV^2, tan^{2}\theta=0.31$ in which the 'high' and the 'low' Ga rates lie far apart and are close to their central values and is of comparable quality to the global best fit, where these rates lie much closer to each other. This is an indication that the best fit in which all solar and KamLAND data are used is not a good measure of the separation of the two Ga data sets, as the information from the low energy neutrino modulation is dissimulated in the wealth of data. Furthermore for the parameter set proposed one obtains an equally good fit to the KamLAND energy spectrum and an even better fit than the 'conventional' LMA one for the reactor antineutrino survival probability as measured by KamLAND.Comment: V2: 15 pages, 3 eps figures, fit improved, final version to appear in Journal of Physics

Cadaveric study: study of lateral circumflex femoral arterial origin in Rajkot

Background: Lateral circumflex femoral artery contributes cruciate, trochanteric and knee joint anastomosis. In addition Lateral circumflex femoral artery flaps are used for the reconstruction of large tissue loss in the head and neck region, aortopopliteal bypass, coronary artery bypass grafting and extracranial intracranial bypass surgery. This work was carried out (a) to study the origin of lateral circumflex femoral artery and (b) to measure and compare (between male and female) the circumference at its origin.Methods: In this cross sectional study, 51 femoral triangles from 26 (18 male and 08 female) human adult cadavers were dissected and studied at P.D.U. government medical college, Rajkot, Gujarat. Site of origin of lateral circumflex femoral artery was identified and noted. The distance of origin of the artery from the origin of profunda femoris artery was measured and noted. Circumference at the level of origin was measured and diameter was calculated. Collected data was analysed by standard statistical formulas with the help of Microsoft excel 2013 and Epi info 7TM software.Results: 90.19% lateral circumflex femoral arteries originated from the profunda femoris artery and remaining 9.81% from the femoral artery. The mean distance of origin of the artery from the origin of profunda femoris artery was 18.44 mm. Lateral circumflex femoral artery circumference and diameter were significantly different between male and female (95% confidence interval, P <0.05).Conclusion: In this presented study maximum distance of origin of the artery from the origin was 65 mm while minimum distance of origin was 6 mm. In addition difference in circumference of the artery was statistically significant.

Effect of plant growth promoting rhizobacteria (PGPR) and IBA treatments on rooting in cuttings of apple (Malus × domestica Borkh.) clonal rootstock Merton 793

The preliminary studies on the effect of different strains of plant growth promoting rhizobacteria (PGPR) alone and in combination with IBA at 1000 ppm on rooting in cuttings of apple clonal rootstock Merton 793 were carried out during 2012-13. The PGPR strains (RG (1)3 – Bacillus sp.), B6 – Bacillus licheniformis and R3 (3) – Sirretia sp. alone failed to induce rooting response in cuttings of apple clonal rootstock Merton 793. The results revealed that IBA 2500 ppm recorded the maximum rooting (65 %), number of primary roots (5.00), length (28.43 cm) and diameter (3.25 mm) of primary roots, fresh (3.67 g) and dry weight (2.59 g) of roots, length of main shoot (134.14cm), diameter of main shoot (8.18 mm), fresh (30.40 g) and dry weight (22.60 g) of shoots in cuttings of Merton 793. However, the PGPR strains RG (1)3 – Bacillus sp., B6 – Bacillus licheniformis and R3 (3) – Sirretia sp. in combination with IBA 1000 ppm showed improvement in rooting of cuttings to the extent of 10, 15 and 5 per cent rooting, respectively and growth of the rooted plants. IBA at 2500 ppm resulted better rooting and growth of rooted plants. Hence, this treatment is suggested for commercial propagation of apple clonal rootstock Merton 793 through cuttings

Magnetic properties of polypyrrole - coated iron oxide nanoparticles

Iron oxide nanoparticles were prepared by sol -gel process. Insitu polymerization of pyrrole monomer in the presence of oxygen in iron oxide ethanol suspension resulted in a iron oxide - polypyrrole nanocomposite. The structure and magnetic properties were investigated for varying pyrrole concentrations. The presence of the gamma - iron oxide phase and polypyrrole were confirmed by XRD and FTIR respectively. Agglomeration was found to be comparatively much reduced for the coated samples, as shown by TEM. AC susceptibility measurements confirmed the superparamagnetic behaviour. Numerical simulations performed for an interacting model system are performed to estimate the anisotropy and compare favourably with experimental results.Comment: 11 pages,8 figure

THE VELOCITY DEPENDENCE OF TECHNNIQUES COMMONLY LINKED WITH LOWER BACK INJURY IN CRICKET FAST BOWLING

The aim of this study was to examine the velocity dependence of shoulder alignment counter rotation, maximum hip-shoulder separation angle, maximum front knee flexion angle and maximum trunk lateral flexion. High-performance fast bowlers (n=17) were required to bowl multiple deliveries in a fast, normal and slower ball category. No statistical association was found between bowling velocity and maximum shoulder counter rotation or knee flexion. Significant associations were found between ball release velocity and trunk lateral flexion and maximum hip-shoulder separation angle. Significant differences were found between the bowling categories for separation angle and knee flexion. A regression analysis showed that trunk lateral flexion and separation angle only accounted for 11% of the ball velocity variance, for the normal delivery (31.3 ms-1)

ADENOKARCINOM JAJOVODA – PRIKAZ BOLESNICE

Mrs. UB aged 35 years came to us with complaints of oligomenorrhoea, lower abdominal pain, haematuria, retention of urine with CT scan report of December 2008 which was suggestive of left sided ovarian tumor. We investigated her with ultrasonography and CA-125 level and primary diagnosis of left sided ovarian tumor was made. On laparotomy it turned out to be primary fallopian tube carcinoma. Abdominal total hysterectomy with bilateral salpingo-oophorectomy with omental and node biopsy was done. On histopathological examination it turned out, as primary serous adenocarcinoma of fallopian tube grade G2PT1(C)PN0. To patient were given two cycles of chemotherapy. Primary fallopian tube carcinomas are quite rare. In routine practice when we come across a case, it is usually diagnosed as an adnexal mass, more commonly as an ovarian tumor. The usual investigations cannot discriminate between the ovarian and the tubal mass. The fallopian tube cancer comes as a surprise on laparotomy. We have to be ready to deal with this condition even when it suddenly crops up.Gospođa UB, životne dobi 35 godina, javila sa smetnjama oligomenoreje, bolima donjeg trbuha, hematurijom i retencijom mokraće. Posjedovala je CT nalaz iz prosinca 2008. godine koji je upućivao na lijevostrani ovarijski tumor. Istražili smo je ultrazvukom i razinom Ca 125 u krvi te je bila postavljena dijagnoza lijevostranog ovarijskog tumora. Učinjena je laparotomija te je nađen primarni karcinom lijevog jajovoda. Ućinjena je totalna abdominalna histerektomija s obostranom salpingo-ooforektomijom s biopsijom omentuma i limfnih čvorova. Histopatološki je utvrđen primarni adenokarcinom jajovoda, stupnja G2PT(1C)PN0. Bolesnici su aplicirana dva ciklusa kemoterapije. Primarni rak jajovoda je zaista rijedak. U rutinskoj praksi se dijagnosticira kao adneksalna tvorba, obično kao ovarijski tumor. Uobičajene pretrage ne mogu razlikovati ovarijsku od tubarne tvorbe. Rak tube Fallopii je iznenađenje prigodom laparotomije. Moramo biti spremni suočiti se s tim stanjem makar ono naglo iskrsne

KamLAND, solar antineutrinos and the solar magnetic field

In this work the possibility of detecting solar electron antineutrinos produced by a solar core magnetic field from the KamLAND recent observations is investigated. We find a scaling of the antineutrino probability with respect to the magnetic field profile in the sense that the same probability function can be reproduced by any profile with a suitable peak field value. In this way the solar electron antineutrino spectrum can be unambiguosly predicted. We use this scaling and the negative results indicated by the KamLAND experiment to obtain upper bounds on the solar electron antineutrino flux. We get $\phi_{\bar\nu}<3.8\times 10^{-3}\phi(^8B)$ at 95% CL. For 90% CL this becomes $\phi_{\bar\nu}<3.4\times 10^{-3}\phi(^8B)$, an improvement by a factor of 3-5 with respect to existing bounds. These limits are independent of the detailed structure of the magnetic field in the solar interior. We also derive upper bounds on the peak field value which are uniquely determined for a fixed solar field profile. In the most efficient antineutrino producing case, we get (95% CL) an upper limit on the product of the neutrino magnetic moment by the solar field $\mu B< 2.8\times 10^{-19}$ MeV or $B_0 \leq 4.9 \times 10^7 G$ for $\mu_\nu=10^{-12}\mu_B$.Comment: 15 pages.

Effect of the size of cuttings (length and diameter) on rooting in cuttings of apple clonal rootstock Merton 793

The study was conducted in net house conditions of fruit Nursery block of Department of Fruit Science, Dr. Y. S. Parmar University of Horticulture and Forestry Nauni, Solan H.P. during 2012-2013 in order to evaluate the effect of size of cuttings (length and diameter) on rooting in cuttings of apple clonal rootstock Merton 793. Cuttings of length (L) viz. 15 cm, 25 cm, 35 cm, 45 cm and diameter ranges (D) viz. 0.75 cm – 1.00 cm, 1.00 cm – 1.25 cm, 1.25 – 1.50 cm were taken. The experiment was laid out in randomized block design (factorial). The cuttings were treated with 2500 ppm IBA (Indole – 3 – butyric acid) as quick dip (10 – 15 seconds) before planting. The results revealed that the cuttings with treatment combination of length (35 cm) and diameter (1.25 cm – 1.50 cm) recorded the highest rooting of cuttings (65 %), number of primary roots (5.00), length of primary roots (28.43 cm), diameter of primary roots (3.25 mm), fresh weight of roots (3.67 g) and dry weight of roots (2.59 g). Hence it is concluded that cuttings of length of 35 cm and diameter of 1.25 cm to 1.50 cm was most suitable for propagation. However, the cuttings of shorter length and diameter, are also able to result in rooting with lower success, therefore, these cuttings would be helpful in case of scarce availability of propagating material
