Strong Gravitational Lensing of Gravitational Waves: A Review
Authors: Grespan Margherita , Biesiada Marek
Published: April 2023

The first successful detection of gravitational waves (GWs) opened up a new window to study a realm of the most violent phenomena in the universe, such as coalescences of binary black holes (BH–BH), binary neutron stars (NS–NS), and mixed (BH–NS) systems, which are mostly inaccessible in the electromagnetic window. On the other hand, strong gravitational lensing of distant sources, such as galaxies and quasars, by other massive objects lying closer along the line of sight has become a powerful tool in cosmology and astrophysics. With the increasing sensitivity of the new generation of GW detectors, the chances to detect a strongly lensed GW signal are increasing. When GWs are strongly lensed, magnification of the signal intensity is expected, unveiling binary compact objects otherwise too distant to be detected. Such systems are important for their plethora of applications. Lensed GWs can be a test for general relativity, constrain mass distribution in galaxies or galaxy clusters, and provide cosmography information independently of the local cosmic ladders. In this review, we will provide a theoretical background of the gravitational lensing of GWs, including the wave optics regime, which becomes important in this context. Then we will describe the possible cosmological and astrophysical insight hidden in these signals, and present the state-of-the-art searches of lensed GWs in the present and future GW observatories.

Rabies is a progressively fatal viral disease affecting a wide variety of warm-blooded animals and human beings. With cattle being major part of Indian livestock population, rabies can result in significant financial losses. Immunization of livestock vulnerable to exposure is the best way to control rabies. The present study was undertaken to investigate the efficacy of a rabies pre-exposure prophylactic vaccine administered through different routes and to sequentially monitor the levels of rabies virus-neutralizing antibody (RVNA) titers in cattle. Thirty cattle were divided into five groups of six animals each. Group I and III animals were immunized with 1 mL and 0.2 mL of rabies vaccine through intramuscular (IM) and intradermal (ID) routes, respectively, on day 0, with a booster dose on day 21; Group II and IV animals were immunized with 1 mL and 0.2 mL of rabies vaccine, respectively, without the booster dose; unvaccinated animals served as a control (Group V). Serum samples were collected on days 0, 14, 28, and 90 to estimate RVNA titers using the rapid fluorescent focus inhibition test (RFFIT). The titers were above an adequate level (≥0.5 IU/mL) on day 14 and maintained up to 90 days in all animals administered the rabies vaccine through the IM and ID route with or without a booster dose. The study indicated that both routes of vaccination are safe and effective in providing protection against rabies. Hence, both routes can be considered for pre-exposure prophylaxis. However, the ID route proved to be more economical due to its dose-sparing effect.

Published: April 2023

The study examined whether the 3R (reframe, prioritize, and reform) communication model intervention can impact parents’ and adolescents’ HPV vaccination acceptability. We used face-to-face methods to recruit participants from three local churches in the Ashanti Region of Ghana. Participants completed pre- and post-intervention assessments based on the validated Theory of Planned Behavior survey. We organized two face-to-face presentations for parents and adolescents separately for parents (n = 85) and adolescents (n = 85). Participants’ post-intervention vs. pre-intervention scores for attitude (mean = 35.46 ± SD = 5.46 vs. mean = 23.42 ± SD = 8.63), knowledge (M = 28.48 ± SD = 5.14 vs. M = 16.56 ± SD = 7.19), confidence (M = 8.96 ± SD = 3.43 vs. M = 6.17 ± SD = 2.84), and intention for vaccine acceptance (M = 4.73 ± SD = 1.78 vs. M = 3.29 ± SD = 1.87) increased significantly (p < 0.001). The intervention showed that for every one-unit increase in the participants’ self-confidence and attitude scores, the odds of the HPV vaccination acceptability increased by 22% (95% CI: 10–36) and 6% (95% CI: 0.1–12), respectively. Intention for vaccine acceptance, F (1167) = 6.89, and attitude toward vaccination, F (1167) = 19.87, were significantly higher among parents than adolescents (p < 0.001), after controlling for the baseline scores. These findings suggest that the intervention targeting parents’ and adolescents’ attitudes and knowledge has the potential to increase HPV vaccination acceptance in Ghana.
A Hybrid Method to Calculate the Real Driving Range of Electric Vehicles on Intercity Routes
Authors: Armenta-Déu Carlos , Cortés Hernán
Published: April 2023

A new method to evaluate the energy consumption and driving range of electric vehicles running on intercity routes is proposed. This method consists of a hybridization of a predictive method and the application of online information during the driving run. The method uses specific algorithms for dynamic conditions based on real driving conditions, adapting the calculation method to the characteristics of the route and the driving style; electric vehicle characteristics are also taken into consideration for the driving range calculation. Real data were obtained from driving tests in a real electric vehicle under specific driving conditions and compared with the results generated by a simulation process specifically developed for the new method run under the same operating conditions as the real tests. The comparison showed very good agreement, higher than 99%. This method can be customized according to the electric vehicle characteristics, the type of route and the driving style; therefore, it shows an improvement in the determination of the real driving range for an electric vehicle since it applies real driving conditions instead of protocol statistical data.

Published: April 2023

Biomechanics is a branch of biophysics that deals with mechanics applied to biology. Corneal biomechanics have an important role in managing patients with glaucoma. While evidence suggests that patients with thin and stiffer corneas have a higher risk of developing glaucoma, it also influences the accurate measurement of intraocular pressure. We reviewed the pertinent literature to help increase our understanding of the biomechanics of the cornea and other ocular structures and how they can help optimize clinical and surgical treatments, taking into consideration individual variabilities, improve the diagnosis of suspected patients, and help monitor the response to treatment.
Application of Deep Learning in Drainage Systems Monitoring Data Repair—A Case Study Using Con-GRU Model

Published: April 2023

Hydraulic monitoring data is critical for optimizing drainage system design and predicting system performance, particularly in the establishment of data-driven hydraulic models. However, anomalies in monitoring data, caused by sensor failures and network fluctuations, can severely impact their practical application. Such anomalies can persist for long periods, and existing data repair methods are primarily designed for short-term time series data, with limited effectiveness in repairing long-term monitoring data. This research introduces the DSMDR, a deep learning framework designed for repairing monitored data in drainage systems. Within this framework, a deep learning model named Con-GRU is proposed for repairing water level monitoring data with long-term anomalies (i.e., 288 consecutive time points) in the pump station forebay. The model iteratively predicts 36 time points at each iteration and uses an iterative approach to achieve the repair process for long-term abnormal monitoring data. The Con-GRU model integrates analysis of forebay water levels, pump status, and rainfall features related to repair, and captures both long-term and local time-dependent features via one-dimensional convolution (Conv1D) and gated recurrent units (GRU). The proposed model improves the accuracy and authenticity of repaired water level data. The results indicate that, compared to existing long short-term memory neural network (LSTM) and artificial neural network (ANN) models, the Con-GRU model has significantly better performance in repairing water level data.

Published: April 2023

The spatiotemporal patterns of key hydrological variables across China were illustrated based on the developed Water and Energy Transfer Processes model in China (WEP-CN model). Time series of four key hydrological variables, namely, precipitation (P), runoff (R), infiltration (Inf), and actual evapotranspiration (ETa), were obtained over 60 years. Then, the temporal trends and spatial differences of these variables were analyzed using the Mann-Kendall and linear methods on a national scale and on the water resource regional scale. Moreover, we explored the drivers and constraints for changes in R, Inf, and ETa. The results showed: (1) Based on the coefficient of variations of P (5.24%), R (11.80%), Inf (2.57%), and ETa (3.77%), R was more fluctuating than the other variables. (2) These variables followed a similar trend of gradually decreasing from the southeast coast to the northwest inland. (3) Changes in R and Inf were caused mainly by P, having correlation coefficients with precipitation of 0.74 and 0.73, respectively. The ETa was constrained by a combination of P and energy. The results improved the refined and quantitative research on hydrological processes in China, identified the differences in hydrological variables between water-resource regions, and provided a useful supplement to the research of the large-scale hydrological process.

Published: April 2023

The drought event of 2018–2019 significantly affected most of Central Europe. In this study, the development and intensity of drought in the Lusatian Neisse river catchment were evaluated, based on the indices of SPI, SPEI, and low flow periods related to hydrological drought. Furthermore, multiannual variability in the drought indices, as well as the trends for air temperature and precipitation totals, were examined for 1981–2020. In the catchment, deficit of precipitation was noticed from autumn 2017 to spring 2020, additionally accompanied by a high thermal anomaly. In the summer seasons, heat waves occurred, which intensified evaporation and increased water deficit. The meteorological drought already appeared in spring 2018, developed in the following months, and became more intensive. The frequency of days with discharges >Q70% exceeded 55%. According to SPI12 and SPEI12, the episode of 2018–2019 can be assessed as the longest period of severe drought in the whole of 1981–2020. The drought caused various consequences in the region. The deterioration of water quality and selected biological indices was one of the effects. In the sector of agriculture, yield reduction in corn and wheat amounted to 33% and 18% in 2018 and 22% and 9% in 2019. In addition, decrease in hydropower generation by more than 30% was noticed.

Published: April 2023

Understanding the intermittent hydraulic connectivity between ephemeral streams and alluvial aquifers is a key challenge for managing water resources in arid environments. The lower Rio Grande flows for short, discontinuous periods during the irrigation season through the Mesilla Basin in southeastern New Mexico and southwestern Texas. Hydraulic connections between the Rio Grande and the Rio Grande alluvial aquifer in the Mesilla Basin vary spatially and temporally and are not well understood. Self-potential (SP) monitoring and time-lapse electric resistivity tomography (ERT) were therefore performed along linear cross-sections spanning the riverbed and flood plain for more than 4 months to monitor the transient hydraulic connection between the river and the alluvial aquifer by measuring time-lapse changes in the electric potential field in the riverbed and flood plain. The monitoring period began on 21 May 2022, when the riverbed was completely dry, continued through the irrigation season while streamflow was provided by reservoir releases from upstream dams, and ended on 4 October 2022, when the riverbed was again dry. SP monitoring data show (1) a background condition in the dry riverbed consisting of (a) a positive electric potential anomaly with a maximum amplitude of about +100 mV attributed predominantly to a subsurface vertical salt concentration gradient and (b) diurnal electric potential fluctuations with amplitudes of 40,000–90,000 mV attributed to near-surface heat conduction driven by weather variability, in addition to (2) a streaming potential anomaly during the irrigation season with a maximum amplitude of about −3500 mV whose transient behavior clearly exhibited a change from the background anomaly to depict exclusively losing streamflow conditions that persisted through the irrigation season. Time-lapse ERT monitoring results depict rapid infiltration of streamflow into the subsurface and imply the river and Rio Grande alluvial aquifer established a full hydraulic connection within a few hours after streamflow arrival at the monitoring site. SP monitoring data show an apparent transition from hydraulic connection to disconnection at the end of the irrigation season and indicate that the transitional phase between connection and disconnection may last substantially longer than the transition from disconnection to connection. The combination of SP and ERT monitoring demonstrated herein shows the potential for broader applications of time-lapse monitoring of hydraulic intermittency and near-surface heat fluxes in different rivers.

Published: April 2023

It is a complicated task to right a capsized ship on the sea bottom because of wave load. Based on the influence of waves on stability and mechanical action, this paper constructs a wave force calculation model by the airy wave theory, and the stability and righting force models of righting a grounded and capsized ship are obtained. The uprighting process of a grounded and capsized ship is simulated by GHS software. In the process, stability and righting force are solved, and the effect of wave parameters on stability and mechanical action is studied. The result shows that when the wave phase is at its origin, the stability and the righting force can be effectively reduced. The wavelength has a significant effect on the hull stability, righting force and ground force in the range of 25 m–35 m. The change of wave height has significant influence on the stability and ground force, but the maximum ground force does not always change regularly with the wave height. Variation of the angle between the hull and the direction of the wave could significantly affect the stability, righting force, and ground force. When the encounter angle is 90°, the righting force is smaller than in other cases, and the maximum negative-going stability, the maximum righting force, and the maximum ground force values are 7.1%, 7.57%, and 3.83%, respectively, 11.7% smaller than those of still water. It is found by comparing several groups of wave parameters that a transverse wave could significantly reduce the difficulty of righting a grounded and capsized ship.

Published: April 2023

The greatest challenges encountered in geospatial studies are related to the availability, accuracy, relevance and cost of the data used. The main mapping techniques currently employed are based on digital data, which are used to create digital elevation models (DEMs). The aim of the present study is to devise and apply methodologies for the generation and validation of high-resolution mapping materials, usable both for local, large-scale analyses, and for the calculation of certain morphometric parameters based on structure from motion (SFM) techniques, applied to images acquired by means of a drone at low cost. As a case study, the ruins of the Belci dam, located in Romania, were analysed, where, with the help of a drone, GIS measurements were performed on the arborescent vegetation of the study area, and a digital terrain model (DTM) of the dam was generated. The costs of such a methodological endeavour are low, which allows for the repetition of the steps involved in devising the maps necessary for such studies on a weekly, seasonal, or annual basis, or after extreme events (floods, landslides etc.). The cartographic materials created in the present study allowed us to calculate the active section of the left earthfill dike of the Belci dam, as well as the volume of material removed by the flood of 1991.

Published: April 2023

This study investigates the trend in monthly and annual rainfall, and minimum and maximum temperature (Tmin and Tmax) in the Savannah region of Togo. The historical data of Mango and Dapaong weather stations from 1981 to 2019 were used. A serial correlation test was applied to all time series to identify serially independent series. A Non-parametric Mann–Kendall (MK) test was applied to serially independent series. The magnitude of the trend was calculated using the Sen’s slope (SS) method. For the data influenced by serial correlation, a modified version of the Mann–Kendall test was applied. An open-source library package was developed in the R language, namely, “mkmodified”. For annual rainfall, results showed a significant increasing trend at Dapaong (p < 0.05) and a non-significant decreasing trend at Mango (p > 0.05) at 95%. There was an increasing trend in the Tmin both at Mango and Dapaong. No statistically significant trend was found at Mango (p > 0.05), while at Dapaong (p < 0.05), a significant trend was found at 95%. Simlarly, there was a statistically increasing trend in the Tmax both at Mango and Dapaong. Rainfall in Dapaong has increased (5.50 mm/year) whereas in Mango, it has decreased (−0.93 mm/year). Tmn increased by 0.04 and 0.008 °C per year in Mango and Dapaong, respectively. Tmax increased by 0.03 and 0.02 °C per year in Mango and Dapaong, respectively. A Rainfall Anomaly Index (RAI) was also used to present a temporal variation in rainfall; the historical series presented drier years. Many studies have analysed the trend of climate parameters in northern Togo, but none of them has specifically targeted the Savannah region that is considered the poorest region of the country.

Authors: Ahmed Ali , Yildirim Gokhan , Haddad Khaled , Rahman Ataur
Published: April 2023

In water resources management, environmental and ecological studies, estimation of design streamflow is often needed. For gauged catchments, at-site flood frequency analysis is used for this purpose; however, for ungauged catchments, regional flood frequency analysis (RFFA) is the preferred method. RFFA attempts to transfer flood characteristics from gauged to ungauged catchments based on the assumption of regional homogeneity. A bibliometric analysis on RFFA is presented here using Web of Science (WoS) and Scopus databases. A total of 626 articles were selected from these databases. From the bibliometric analysis, it has been found that Journal of Hydrology and Water Resources Research are the two leading journals reporting RFFA research. In RFFA research, leading countries include Canada, USA, UK, Italy and Australia. In terms of citations, the top performing researchers are Ouarda T, Burn D, Rahman A, Haddad K and Chebana F. Future research should be directed towards the identification of homogeneous regions, application of efficient artificial intelligence (AI)-based RFFA models, incorporation of climate change impacts and uncertainty analysis.
Pipeline-Burst Detection on Imbalanced Data for Water Supply Networks
Authors: Wang Hongjin , Liu Tao , Zhang Lingxi
Published: April 2023

Data-driven methods based on samples from a supervisory control and data acquisition system have been widely applied in water-supply-network burst detection to save unexpected economic and labor costs. However, the class imbalance problem in actual on-site monitoring needs to be revised to improve the performance of data-driven methods. In this study, we proposed a domain adaptation method to generate minor-category samples (pipeline-burst samples in general) of arbitrary pipe networks utilizing theoretical hydraulic models. The proposed method transferred pipeline-burst data generated from a random water supply network with theoretical hydraulic models to an actual imbalanced dataset. Accordingly, we established a machine learning model exploring a mapping matrix between two domains for minority-category data transfer. The experimental validation first verified the effectiveness and reliability of the proposed method between two customized water supply networks in terms of their bust recognition accuracy, model parameter sensitivity and time efficiency. Then, an actual monitoring dataset from a working water supply network was used to prove the suitability and compatibility of the proposed method. A bust-point location method was also provided based on the detection results of pipeline-bursting events. The validations show the superiority of our proposed approach for the imbalance data problem in pipe burst detection.
Quadruple-U Auxiliary Structure-Based Receiving Coil Positioning System for Electric Vehicle Wireless Charger
Authors: Li Chuan , Yang Yi , Cao Guimei
Published: April 2023

In order to strike a balance between economic development and green travel, electric vehicles with wireless charging have become one of the first choices for future transportation. Misalignment between the transmitting coil and receiving coil in wireless charging systems decreases power capacity and efficiency to a great extent. Hence, the detection of whether the electric vehicle enters the effective charging area is a hot issue in the current research. In this paper, a receiving coil positioning approach integrated with a quadruple-U auxiliary structure is proposed. The designed quadruple-U auxiliary structure with cruciform distribution consists of four U-shaped coils, which are inspired by the solenoid coil. Based on the symmetry of the auxiliary structure, a receiving coil positioning method is proposed by measuring the load voltages of each U-shaped coil working independently. Coordinates can be obtained by retrieving the measured results with the database established in advance. The positioning method has the advantages of wider positioning ranges, higher positioning accuracy, and not changing the structure of the receiving coil. Furthermore, the specific magnetic coupler is simulated by a three-dimensional finite element modeling tool and was verified by an experiment on a prototype. During the positioning process, the positions distributed throughout the ΔX ∈ [−300 mm, 0 mm]∩ΔY ∈ [−300 mm, 300 mm] positioning range were tested. The experimental results indicate that all of the tested positions are accurate to within 10 mm, with a 160 mm transfer distance. Meanwhile, combined with the symmetry of the auxiliary structure and the test results, it can be indicated that the positioning range can reach ΔX ∈ [−300 mm, 300 mm]∩ΔY ∈ [−300 mm, 300 mm].
Adaptive Sliding Mode Control for Yaw Stability of Four-Wheel Independent-Drive EV Based on the Phase Plane
Authors: Zhou Zhigang , Zhang Jie , Yin Xiaofei
Published: April 2023

Aiming at the yaw stability problem of a four-wheel independent-drive electric vehicle (EV) during steering, this paper proposes an adaptive sliding mode control strategy (ASMC) for yaw stability based on the phase plane. The control strategy adopts hierarchical control. The upper layer is the ASMC controllers based on particle swarm optimization (PSO). Aiming at the chattering problem of sliding mode controller, the approach law is designed as the adaptive approach law, which changes with the change of system state by using the adaptive control principle; to minimize the response delay and tracking error, the control system is taken as the object to find a set of optimal parameters for a constant velocity approach rate based on PSO. The middle level is a joint controller, which uses the established β−β˙ phase plane stability region boundary model to control the upper-level controllers jointly. When the vehicle is in the stable region, the ASMC controller for the yaw rate is used to determine the yaw moment; when the vehicle is outside the stable region, the final yaw moment is determined by the ASMC controller for the yaw rate and the ASMC controller for the sideslip angle, to restore the stability of the vehicle. The lower layer is a torque optimal distribution controller, which converts the yaw moment into torque and optimally distributes it to four wheels. Finally, Simulink and CarSim platforms are used for joint simulation. The results prove that the proposed control strategy can effectively reduce the error between the actual and the ideal value of control parameters and improve the vehicle’s stability when steering.

Published: April 2023

Quality of Life at Work (QLW) involves both physical and environmental aspects, as well as psychological aspects. A better quality of life can have a positive impact on the performance of workers. QLW is concerned with providing a more adequate, beneficial and fundamental workplace for the activity of any organization and would be more than a benefit to the employee, but also a necessary factor for the survival of the company, since the satisfaction of workers also influences the performance and success of the organization. Quality of life at work should involve the assessment of the level of health of employees, lifestyle and organizational climate as a whole and there is no satisfactory standard of quality of life at work for all, since each person has their own need to be achieved, highlighting the importance of the personal needs of workers for the organization to succeed. Thus, it is important that companies worry about the QWL of their employees, since inappropriate practices in the work environment generate a negative impact on the physical and emotional health of employees and, consequently, on the financial health of the company.

La estadificación del cáncer de mama tiene como objetivo determinar la extensión de la enfermedad, definir el tratamiento y el pronóstico de la misma. La American Joint Committee on Cancer (AJCC) ha asignado el estadio utilizando el tamaño del tumor (T), la presencia de compromiso ganglionar (N), y la presencia o ausencia de metástasis a distancia (M). Con el advenimiento de la biología molecular, se integra a la estadificación anatómica la información pronóstica con el grado histológico, el estado de los receptores hormonales y el resultado del receptor de HER2. En el Instituto Nacional de Cancerología (INC), la incorporación del TNM pronóstico trajo consigo un aumento de estadio en el 14,47% de los casos y una disminución en el 40,3%; este resultado se atribuyó en parte al mayor porcentaje de tumores localmente avanzados dentro de la institución. Por subtipo biológico, los tumores luminales presentan mayor riesgo de metástasis óseas, los tumores triple negativo a pulmón y sistema nervioso central; y los tumores HER2 a SNC, hígado y pulmón. Teniendo en cuenta este compromiso a distancia, los métodos de estadificación comúnmente utilizados son gammagrafía ósea (GO), radiografía de tórax (RxT), ecografía hepática (UH) y/o tomografía computarizada (TC).En el caso de identificar hallazgos sospechosos en estos exámenes o si el cuadro clínico del paciente lo sugiere, se realizan estudios adicionales como TC o resonancia magnética nuclear (RMN). Los cambios en la estadificación clínica y la biología del cáncer de mama motivaron a las Unidades de Seno y Tejidos Blandos y Oncología Clínica del Instituto Nacional de Cancerología a revisar la evidencia científica disponible para recomendar la pertinencia de los estudios de extensión.

Importancia de la participación de los adultos mayores en la evaluación los servicios de salud
Authors: López-Estrada Paola , Muñoz-Guarneros Carlos
Published: April 2023

La calidad en los servicios de salud es un derecho de los usuarios, por ello se requiere de una visión holística, enfocada en el bienestar individual y social de la población. Siendo necesaria una constante evaluación que debe considerar las características sociodemográficas de la población que pretende atender. Por ello, al haber un notable envejecimiento en la población mexicana se plantea como relevante darle importancia a su participación en la evaluación de servicios de salud. Diversos estudios resaltan la inconformidad por parte de adultos mayores, respecto al trato que reciben por el personal de las instituciones de salud. Sin mencionar el estigma que se tiene respecto al envejecimiento en la cultura mexicana, donde las opiniones y puntos de vista de este grupo poblacional pierden relevancia. Finalmente se concluye que, los nuevos lineamientos dictados por Organizaciones Internacionales recalcan la importancia de la participación de los adultos mayores en todos los ámbitos sociales, incluirlos en la evaluación de la percepción de la calidad de los servicios de salud que reciben permitirá realizar modificaciones para mejorar la atención que reciben.

A síndrome nefrite tubulointersticial e uveíte (síndrome TINU) é uma condição autoimune multissistêmica incomum caracterizada pela presença de nefrite tubulointersticial e uveíte na ausência de outras doenças que justifiquem o quadro. O tratamento com objetivo imunossupressor é usualmente realizado com corticoterapia oral, embora não haja um protocolo baseado em evidências específico para tal condição. Neste caso relatamos a história clínica de uma paciente de 63 anos, hipertensa e pré-diabética, que apresentou um quadro importante de lesão renal aguda e, posteriormente, durante internamento desenvolveu quadro de uveíte unilateral. Após biópsia renal, foi constatada presença de nefrite tubulointersticial, tratando-se de um caso de síndrome TINU, após excluídas outras causas. Neste caso, foi optada pela pulsoterapia com resultado satisfatório.

Diabetic Ketoacidosis (DKA) in pregnancy has serious implications on maternal and fetal outcomes.
Increased incidence of diabetes worldwide has led to more number of pregnancies being susceptible to
this complication, necessitating a multidisciplinary team management in a critical care setting. There are several challenges
with respect to diagnosis and management of this condition. An understanding of the physiological changes in pregnancy, the
impact of precipitating events as well as patient education and emphasis on adherence to treatment are key elements in care
provision. Infection and poor compliance to insulin are the most common triggers for ketoacidosis and can occur at even lower
blood sugar thresholds in pregnancy. Prevention, early diagnosis, aggressive treatment and timely indicated delivery form the
pillars of successful management of DKA in pregnancy. This case report demonstrates that increased awareness of DKA with
immediate recognition and a successful multidisciplinary approach are mandatory for positive pregnancy outcomes.

A 26 year old male patient presented with abdominal distension following ingestion of liquid nitrogen
and was diagnosed to have massive pneumoperitoneum both clinically and radiologically. Patient
underwent emergency laparotomy in search of perforation, the stomach, Intestines was examined and no hollow viscous
perforation was found. All abdominal contents were normal, no tissue necrosis or haemorrhage, no free uid or bleeding was
found in the abdomen. Two abdominal drains were placed in the lesser sac and the pelvis and abdomen were closed. The
patient was stable post operatively and tolerated oral feeds and discharged on 7th post operative day. Our study revealed that
despite of having massive pneumoperitoneum, site of perforation cannot be identied

Authors: Pramida B. , Shameem Khathija , Deepika Deepika , Bhavani M.
Published: April 2023

Introduction : Anaemia is a decrease in the oxygen-carrying capacity of the blood. RBC histogram is a standard part and is routinely generated by automated cell analyzers. The well-known Coulter principle of counting and sizing the cells provides a basis for generating a histogram. The peripheral blood smear has been the main diagnostic aid in establishing the etiology of anaemia. Examining the blood lms routinely has facilitated the interpretation of various haematological disorders. Materials and Methods: The present study was carried out in the haematology laboratory of Kamineni Institute of Medical Sciences, Narketpally over a period of 3 months. EDTA blood samples from 100 anaemic patients were run in a six-part Sysmex analyzer and peripheral smears were prepared and examined. Results: A total of 100 patients with peripheral blood smear and RBC histogram from automated analyzer were studied. Out of 100 patients, 60% were females and 40% were males. Normocytic normochromic anaemia (50%) was the most commonly observed anaemia in the present study followed by microcytic hypochromic anaemia (40%). Most common histogram pattern observed was normal bellshaped curve. In normocytic normochromic anaemia (50%), the majority of the cases show a normal bell-shaped curve (37%) and the remaining 13% of cases showed broad-based curve. In microcytic hypochromic anaemia (40%) most common histogram pattern observed was shift to the left. In dimorphic anaemia (8%) histogram pattern observed was bimodal peak with a broad base. In macrocytic anaemia (2%) most commonly seen histogram pattern was shift to the right. Conclusion: Histogram plays an additional role with peripheral smear for diagnosing RBCs disorders. Even in the age of molecular analysis, the blood smear examination remains an important diagnostic tool.

Introduction The relationship between various ovarian diseases and its treatment on ovarian reserve is a
subject of debate. It is difcult to determine the real impact of the ovarian surgery on future fertility of
women. This study aimed to assess the effect of conservative ovarian surgeries on ovarian reserve in reproductive age women
by correlation of preoperative and post operative S.AMH. Materials And Methods: This prospective study included 66 patients
of reproductive age with various ovarian diseases. Ethical clearance was obtained from Institutional ethics committee and
informed consent from all recruited patients. They were grouped into inammatory or benign disease, malignant disease and
ovarian endometrioma by histology. S. AMH was compared in the three groups pre-operatively, after 4 weeks and after 3-6
months of surgery. The statistical analysis was done with SPSS version 15. Result: Mean decline in S> AMH at 4 weeks was
0.16, 0.40 and 0.33 respectively for inammatory/benign, malignant and endometrioma groups. Similarly, after 3-6months, it
was 0.17, 0.75 and 0.37 respectively for the three groups. Statistically, both malignant and endometrioma groups showed
signicantly higher decline as compared to inammatory/benign group (p<0.001). Conclusion: Baseline S.AMH levels are
signicantly lower in endometrioma and malignant ovarian tumours as compared to benign ovarian tumours. They show a
signicant decline following surgical treatment in all ovarian diseases but the decline is signicantly more endometrioma and
malignancy.

To avoid complications, CSF rhinorrhea needs to be treated appropriately. This study aimed to provide an overview of the patient data, as well as information on the causes, leak sites, contributing factors, and treatment outcomes of CSF rhinorrhea. Over a period of 1 year, a comprehensive study was carried out on patients who presented to Government General Hospital-Kakinada with an active CSF leak and did not respond to medical treatment. CT, CT_cisternography, and MR-Cisternography were used to collect data from clinical records. There were 15 cases, nine of which were traumatic leaks and six were spontaneous leaks. The cribriform plate was the most common location for leakage (8/15 cases), and all of those cases were successfully repaired using endoscopic surgery. The Keros Type II is most common based of depth of olfactory fossa. Imaging plays a crucial role. The standard treatment of CSF leak repair is endoscopic repair through endonasal route.
