bValues for foreshocks and aftershocks in real and simulated earthquake sequences
Authors: Knopoff L. , Kagan Y. Y. , Knopoff R. 
Published: June 2021

abstractThe differences in b values between foreshock and aftershock sequences can be shown to be a statistically significant property of real earthquake sequences if a sufficiently large number of cases is considered, i.e., if the catalogs are long enough. These differences depend on the particulars of the data processing procedures used to define the sequences, such as space-time windowing and definition of cutoff magnitude thresholds for completeness of catalogs, as well as other magnitude cutoffs. They are also a statistically significant property of long artificial, or synthetic catalogs in which all subsequent earthquakes are modeled as resulting from a stochastic time delay applied to predecessor earthquakes. As a consequence, we make the conjecture that the difference in b values is due to subtle asymmetries in data processing procedures rather than differences in the physical environment before and after a large earthquake.
Attenuation of regional phases in Western Europe
Authors: Nicolas Marc , Massinon Bernard , Mechler Pierre , Bouchon Michel 
Published: June 2021

abstractThe purpose of this study is to evaluate the attenuation of local seismic phases in France. We use the 25 short-period vertical stations of the French seismic network and select a set of six earthquakes which occurred in France or in its vicinity, and within a range of epicentral distances from 1° to 10°. We have determined the attenuation versus distance for Pn, Sn, Pg, and Lg phases and analyzed the influence of frequency. Attenuation coefficients for Pn and Sn waves are of the order of 2. They are slightly higher for Pg (2.3) and Lg (2.5) waves, but the amplitude of these waves is largely dependent on the azimuth of propagation. Lg/Pg ratios present a large scatter between 1 and 10 with a mean trend around 3 to 4. We found that the Lg anelastic attenuation coefficient is of the order of 0.2 deg−1 at 1 Hz, a result to be compared with the values of 0.07 deg−1 (Eastern United States), 0.15 deg−1 (Northern USSR), and 0.35 deg−1 (south of the Caspian Sea) obtained by Nuttli (1973, 1981). The quality factor, computed for each one of these local phases, shows a clear dependence on frequency, increasing from around 100 at 1 Hz to around 1000 at 16 Hz.
Inverting travel times with a triplication
Authors: Jarosch Hans S. 
Published: June 2021

abstractA new technique has been developed to overcome difficulties which arise when body-wave data in the form of T-delta is reduced to the tau-p form in the presence of cusps. The technique uses sophisticated constrained spline fits to allow for constraints on the derivatives and thus eliminates the possibility of points of inflexion occurring as well as making sure that the curvature is in the right direction. Having arrived at a good fit to the T-delta data with a single spline, the tau-p curve can be derived which has taken the cusp properly into consideration. The tau-p curve is then inverted with a new linear inversion method, which again takes into consideration whether a particular point lies on a prograde or retrograde branch.The technique is applied to the lunar seismic data, where at least one triplication is presumed to occur for the P-wave travel-time curve. It is shown that the present analysis is not accurate enough to address itself to the problem of a possible lunar core, since there are insufficient data points for events close to the antipode of the center of the lunar network.

Authors: Ganekal Sunil , Ganekal Varun 
Published: June 2021

To compare the visual acuity outcomes after surgical treatment of epiretinal membranes (ERM) in cases with and without ectopic inner foveal layers (EIFL). : A total of 100 eyes of 98 patients with idiopathic ERM were retrospectively staged according to the newer OCT classification and divided into two groups on the basis of presence or absence of EIFL. The two groups were evaluated for various parameters including visual acuity, thickness of the EIFL, re-appearance of the foveal contour, outer retinal changes and complications before and after ERM peeling. Correlation analysis was done using chi square test and p-values were obtained for corresponding variables.: Of 100 eyes with ERM, 20% had stage 1, 29% had stage 2, 42% had stage3 & 9% had stage 4 disease. VA was worse in eyes with EIFL as compared those without it. Correlation of VA with EIFL thickness however was not significant. Surgical removal of ERM didn’t alter EIFL frequency though the thickness decreased. New EIFL appeared in 4% eyes and 35% demonstrated thickened fovea after surgery. Anatomical reappearance of foveal contour was poorer in eyes with EIFL. Outer retinal changes were more common in non EIFL eyes. Lamellar holes and nontractional cysts were more common in EIFL eyes.: EIFL is a significant prognostic tool to predict the visual outcome of surgery in cases of Epiretinal membrane. EIFL eyes did not regain foveal contour, had less outer retinal damage but were associated with poorer visual outcomes.

We aim to assess the association of ocular manifestations with chronic kidney disease and correlating it with the stages of chronic kidney disease.It was a cross-sectional study carried out in tertiary medical college in Central Maharashtra. A total of 84 patients were examined over a period of 18 months. Detailed ocular and systemic examinations were undertaken. Dilated fundus evaluation was done with slit lamp biomicroscopy and indirect ophthalmoscopy. Positive anterior and posterior segment findings were noted.Out of 168 eyes of 84 patients, 111 eyes had posterior segment involvement, 25 eyes had anterior segment involvement and 22 eyes had both anterior and posterior segment involvement. Most common posterior segment pathology was hypertensive retinopathy followed by diabetic retinopathy. Anterior segment findings did not correlate with the stage of the disease whereas severe stage of diabetic retinopathy was present in later stages of chronic kidney disease.Present study showed a strong association of ocular manifestation in chronic kidney disease. Ocular involvement in CKD patients if not detected early can lead to permanent and irreversible visual loss, therefore pressing the need for ophthalmic examination in such cases.

To compare peribulbar and subtenon anaesthesia in patients undergoing cataract surgery. In a hospital based randomised comparative interventional study, patients who underwent cataract surgery were randomised into two groups, one receiving peribulbar and the other subtenon anaesthesia. Pain during administration, pain during surgery, chemosis, subconjunctival haemorrhage globe akinesia were noted and compared in the two groups. Any other complications which occur also noted. The pain during administration was significantly lesser in subtenon injection as compared to peribulbar anaesthesia. Pain during surgery was comparable in the two groups. Incidence of subconjunctival haemorrhage and chemosis was more in subtenon injection as compared to peribulbar anaesthesia. Globe akinesia was achieved more effectively in subtenon injection as compared to peribulbar injection. The subtenon anaesthesia is comparable to peribulbar anaesthesia with few additional advantages and is recommended as safe and effective alternative to peribulbar anaesthesia for cataract surgery.

Published: June 2021

To evaluate the rise in intraocular pressure (IOP) in post cataract surgery patients who received topical steroids.Patients in the age group of 50-75 years and both sexes who were coming to ophthalmology OPD at a tertiary care hospital of Western Maharashtra were studied. 500 subjects who underwent uncomplicated cataract surgery were taken into consideration; both age and sex matched. All patients were screened for raised intraocular pressure by Perkin’s tonometer preoperatively and at 5th day, 2nd week, 4th week, 6th week and 8th week postoperatively. Patients were allocated into two groups: either topical Prednisolone acetate e/d (1%) (Group I) or Dexamethasone e/d (0.1%) (Group II) started six times for 1st week (considering the cells in anterior chamber &#60;2+) & then tapered off subsequently in the following weeks for a period of 5 weeks (starting with six times for 1st week, then tapering to 4 times for the next week, 3 times for the next week, 2 times for the next week, 1 time for the next week and then stopped).In our study group, the prevalence of steroid-responders was 3.6% with 0.8% showing mild rise, 2.8% showing moderate rise in IOP on the fourth week of topical steroid usage. There was no difference in the mean IOP rise with the usage of two different topical steroids (E/d Prednisolone acetate (1%) and E/d Dexamethasone(0.1%)) in our study. The highest mean IOP was noted at the 5th postoperative day (20.26 mmHg) which was due to inflammation & there was a gradual decrease in IOP in the subsequent weeks of follow-up till 8th week. While as duration after cataract surgery progress till 8th week of follow up, moderate rise in IOP occurs which gradually comes down to mild rise till 8th week of follow-up.Steroid-induced IOP elevation typically occurs after 4 weeks of beginning steroid therapy and the prevalence of steroid responders in post cataract surgery patients was established.

Published: June 2021

A potential complication of cataract surgery is posterior capsular rent, where PCIOL can’t be implanted. Primary Iris claw implantation means that the IC-IOL is implanted in the same setting after cataract removal. While secondary Iris claw lens implant is done in an aphakic eye without capsular support and post cataract surgeries when the eye is left aphakic. To compare the visual outcome in cases of primary and secondary iris claw lens implantation after cataract surgery.This was a hospital-based Prospective Interventional Longitudinal study,conducted on patients in a tertiary care centre, in Western Maharashtra from September 2018 to August 2020. 31 eyes underwent primary iris claw implant and 19 underwent secondary iris claw implant. Highly significant difference in visual acuity preoperatively due aphakia among subjects who underwent secondary iris claw implantation (p=0.000) was seen. Highly significant difference in visual acuity post operatively till 15 days was also seen due to less corneal oedema& inflammation in patients who underwent secondary iris claw implantation. No significant difference in visual acuity was seen on day 40 as lens was put in both the groups and the signs of inflammation had reduced (p=0.759).Overall visual outcome after 40 days is comparable in primary and secondary cases. It is better to do a primary retro fixated iris claw implantation, as in case of a secondary implant the patient will have undue anxiety, to undergo a second surgery along with increased financial burden and patient can develop complications due to aphakia.

Published: June 2021

Aim: The purpose of this study was to reveal mid-term outcomes by retrospectively investigating patients who underwent total knee arthroplasty with a posterior stabilized design.
Material and methods: The study included a total of 68 knees of 52 patients with completed follow-up data who underwent PCL substituting (PS) total knee arthroplasty due to a diagnosis of primary or secondary osteoarthritis. The 52 patients comprised 45 (86.5%) females and 7 (13.5%) males with a mean age of 65.2±9.32 years (range, 30-82 years). The American Knee Society criteria were adopted for assessment of patient knee scores and functional knee scores. The Total Knee Prosthesis Radiological Evaluation criteria were applied for radiological evaluation of the patients.
Results: The mean follow-up period of the patients was 32.1 ± 9.85 months (range: 18-60 months) and the Knee Society Scores (KSS) were 41.5 (range: 26 - 58) preoperatively, and 84.3 (range: 51 - 97) postoperatively. The mean preoperative and postoperative range of motion was 88.2º (range: 60º - 100º), and 106.7º (range: 90º - 120º), respectively. Two-stage revision surgery was applied to one patient due to deep infection. No cases of aseptic loosening were observed. Implant survivorship, and excellent and good results according to the functional knee score were reported as 98.8%, 41.1%, and 32.3%, respectively.
Conclusion: Positive patient outcomes were obtained with the use of PS total knee arthroplasty in patients with severe osteoarthritis and there was no evidence of loss in mid-term follow-up.

Published: June 2021

Foi verificada a distribuição, feita a identificação taxonômica e a caracterização morfológica das espécies de monilófitas (samambaias) aquáticas de quatro lagoas pequenas temporárias e duas perenes localizadas ao longo da estrada que corta o setor industrial da área Itaqui-Bacanga, na ilha de SãoLuís - MA, durante o período de junho a setembro de 2011. As espécies encontradas nos ambientes amostrados foram Salvinia auriculata, Salvinia molesta (Salviniaceae) e Ceratopteris thalictroides (Pteridaceae). As três espécies apresentaram caráter de ocorrência anual e as Salviniaceaeestiveram amplamente distribuídas nos ambientes aquáticos observados. Dentre as monilófitas amostradas, apenas o gênero Salvinia apresenta heterosporia, com a presença de megasporângios e microsporângios. O gênero Ceratopteris, por sua vez, é homosporado, apresentando apenas esporos masculinos, que possuem um potencial para desenvolver gametófitos que futuramente poderão ser masculinos ou hermafroditas. A superfície foliar (tricomas), no caso de Salvinia, e o caule, no caso de Ceratopteris, são importantes estruturas na flutuabilidade das plantas. As três espécies apresentam adaptações morfológicas fundamentais para o seu estabelecimento e desenvolvimento nesses locais.Distribution, morphology and anatomy of aquatic Monilophyta (ferns) in small ponds at the area Itaqui-Bacanga, São Luís Island-MAABSTRACTDistribution, taxonomic identification and morphological analysis of aquatic species of Monilophyta (ferns) were carried out in four perennial and two temporary ponds located along the road through the industrial area Itaqui-Bacanga, at the São Luís Island – MA, from June to September 2011. The species found in the study sites were Salvinia auriculata, Salvinia molesta (Salviniaceae) and Ceratopteris thalictroides (Pteridaceae), all presenting an annual occurrence in nature and Salviniaceae were widely distributed in the ponds observed. Among the monilophytes sampled, only the Salviniagenus shows heterosporia, with the presence of megasporangia and microsporangia. The genus Ceratopteris in turn is homosporate, presenting only male spores, which have a potential to develop gametophytes that in the future may be male or hermaphrodite. The leaf surface (trichomes), in the case of Salvinia, and the stem, in the case of Ceratopteris, are important structures in the buoyancy of plants. The three species show important morphological adaptations for their establishment and development in these places.Keywords: Aquatic euphillophyta; Occurrence; Morphological adaptations; Ponds.
MACROINFAUNA INTERMAREAL DAS PRAIAS ARENOSAS DO LITORAL DE ARACAJU, SERGIPE, REGIÃO NORDESTE DO BRASIL = INTERTIDAL MACROINFAUNA OF THE ARACAJU SANDY BEACHES, SERGIPE, NORTHEASTERN BRAZIL

Praias arenosas são ambientes altamente dinâmicos que abrigam uma rica fauna adaptada às condições de instabilidade dos sedimentos. Nesse estudo, a estrutura e a composição da macrofauna de quatro praias arenosas do litoral de Aracaju (Sergipe, NE do Brasil) foram analisadas. As praias foram classificadas, em sua maioria, como dissipativas. O número total de espécies variou entre 14 e 17 espécies, enquanto que a densidade média total variou entre 65,50±9,29 e 169,50±30,52 indivíduos/m², sendo o bivalve Donax gemmula e os poliquetas Hemipodia californiensis e Orbinia sp. as espécies mais abundantes. Diferenças observadas na macrofauna provavelmente refletem os diferentes graus de urbanização e/ou intensidade de uso das praias analisadas. Quando comparado com outras praias do litoral sudeste e sul do Brasil, os valores de riqueza de espécies foram semelhantes, no entanto, os valores de densidade foram extremamente baixos, corroborando com o padrão latitudinal o qual prediz uma redução na abundância das espécies de zonas temperadas em direção à zona tropical.ABSTRACTSandy beaches are highly dynamics environments which harbor a rich fauna adapted to sediment instability. In this study, the number of species and the density of the intertidal macrofauna of the four sandy beaches of the Aracaju coast (Sergipe, NE Brazil) were analyzed. The beaches were classified as dissipative. The number of species ranged from 14 to 17 species, whereas total density ranged from 65.50±9.29 to 169.50±30.52 individuals/m². The bivalve Donax gemmula and the polychaete Hemipodia californiensis and Orbinia sp. were the most abundant species. Observed differences in the intertidal macrofauna probably reflect the different urbanization levels and/or intensity of use of the analyzed beaches. When compared to others beaches of the southern/south region of the Brazil, the number of species values were quite similar. However, density values were extremely lower, corroborating with previous latitudinal patterns, where decrease in the macrofauna abundance from temperate to tropical beaches are expected.
