bACkGROUND Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare epithelial tumor that primarily affects young women. Since the condition is often asymptomatic or presents with non-specific symptoms, its diagnosis can be difficult. CASE SUMMARY This report details the case of a 15-year-old girl who presented with a 2-year history of abdominal pain, with no significant findings during physical examination. Abdominal ultrasound revealed a well-defined heterogeneous solid-cystic mass in the epigastric region, likely originating from the tail of the pancreas. A subsequent contrast-enhanced computed tomography scan indicated a well-defined cystic lesion with an enhancing solid component and capsule in the tail of the pancreas, suggestive of a cystic neoplasm. The patient underwent an open distal pancreatectomy with splenectomy, and histopathological analysis confirmed the diagnosis of SPN of the pancreas. CONCLUSION This case highlights the risk of SPN in adolescent girls and the necessity of early diagnosis and intervention for better outcomes. © The Author(s) 2025.

Enhanced visible-light photocatalytic activity of multi-elements-doped ZrO_2 for degradation of indigo carmine

引用

Journal of Rare Earths 2015年第5期33卷 498-506页

作者： E.S.Agorku A.T.kuvarega b.b.Mamba A.C.pandey A.k.Mishra Department of Applied Chemistry University of Johannesburg University of South Africa College of Engineering Science and Technology Nanotechnology & Water Sustainability Research Unit Florida Campus Nanotechnology and Application Centre University of Allahabad

In this study, C,N,S-doped ZrO2 and a series of Eu doped C,N,S-ZrO2 photocatalysts were synthesized by a coprecipitation method using thiourea as the source of C, N and S and Eu（NO3）·6H2O as source of Eu. The materials were characterized by X-ray dif-fraction （XRD）, Raman spectroscopy, Fourier transform infrared spectroscopy （FTIR）, UV-visible diffuse reflectance spectroscopy, scanning electron microscopy （SEM）/energy dispersive X-ray spectroscopy （EDX）, and transmission electron microscopy （TEM）. Indigo carmine （IC） was chosen as a model for organic pollutants and used to evaluate the photocatalytic performance of the photo-catalysts under simulated solar light. Commercial ZrO2 was used as a reference material. XRD and Raman results indicated the for-mation of both tetragonal and monoclinic phase ZrO2 with particle size ranging from 8–30 nm. Multi-element doping had a great in-fluence on the optical responses manifested as red shift in the absorption edge. The highest photocatalytic activity towards IC was observed for the Eu,C,N,S-doped ZrO2 （0.6 mol.%Eu） sample （k=1.09×10–2 min–1）. The commercial ZrO2 showed the lowest photo-degradation activity （k=5.83×10–4 min–1）. The results showed that the control of Eu doping in the C,N,S-ZrO2 was very important in reducing electron-hole recombination. The synergistic effect of Eu, C, N, and S in the ZrO2 matrix led to enhanced utilization of simulated solar energy for the degradation of IC through narrowing of bandgaps.

Path planning in uncertain environment by using firefly algorithm

引用

Defence Technology（防务技术） 2018年第6期14卷 691-701页

作者： b.k.Patle Anish pandey A.Jagadeesh D.R.Parhi Department of Mechanical Engineering CVR College of Engineering School of Mechanical Engineering KIIT University Department of Mechanical Engineering Audisankara Group of Institutions Department of Mechanical Engineering NIT Rourkela

Autonomous mobile robot navigation is one of the most emerging areas of research by using swarm intelligence. Path planning and obstacle avoidance are most researched current topics like navigational challenges for mobile robot. The paper presents application and implementation of Firefly Algorithm(FA)for Mobile Robot Navigation(MRN) in uncertain environment. The uncertainty is defined over the changing environmental condition from static to dynamic. The attraction of one firefly towards the other firefly due to variation of their brightness is the key concept of the proposed study. The proposed controller efficiently explores the environment and improves the global search in less number of iterations and hence it can be easily implemented for real time obstacle avoidance especially for dynamic environment. It solves the challenges of navigation, minimizes the computational calculations, and avoids random moving of fireflies. The performance of proposed controller is better in terms of path optimality when compared to other intelligent navigational approaches.

Standardization of harvesting age of bamboo shoots with respect to nutritional and anti-nutritional components

引用

Journal of Forestry Research 2013年第1期24卷 83-90页

作者： Ashok k. pandey Vijayalakshmi Ojha Tropical Forest Research Institute Indian Council of Forestry Research and EducationP.O. RFRCMandla RoadJabalpur- 482 021India.

bamboo shoots can be harvested at different ages but the data on the changes in nutritional composition with age are scanty. We standardized harvesting age of bamboo shoots in central India to obtain best quality produce with respect to nutritional composition. The shoots harvested on different days （2–20 days after emergence from ground） were analyzed for their nutritional （dietary fibres, carbohydrates, proteins, total phenols, ascorbic acid, sodium, potassium, phosphorus, calcium, magnesium and phenolic acids） and anti nutritional （cyanogen） constituents. A significant variation （at p ≤ 0.5） was observed in the nutritional composition of shoots of Dendrocalamus asper, D. strictus and bambusa tulda harvested at different days. An overall decrease was observed in proteins and total phenols while dietary fibres and carbohydrates increased with ages. Significant variation （at p ≤ 0.5） was also observed in phenolic acids while minerals did not vary significantly. Results revealed that the optimum harvesting age for D. asper, D. strictus and b. tulda was on 10–14 days, 6–10 days and 10–16 days （after emergence from the ground） respectively. These results can be used to obtain quality bamboo shoots.

作者： Debashish Dash Chandan k pandey Saurabh Chaudhury Susanta k Tripathy Department of Electrical Engineering National Institute of TechnologySilchar Assam Department of Electronics and Communication Engineering National Institute of TechnologySilchar Assam

We present an analysis of structural, electronic, and mechanical properties of cubic titanium dioxide （TiO2） using an all electron orthogonalzed linear combinations of atomic orbitals （OLCAO） basis set under the framework of density functional theory （DFT）. The structural property, especially the lattice constant a, and the electronic properties such as the band diagram and density of states （DOS） are studied and analyzed. The mechanical properties such as bulk moduli, shear moduli, Young＇s Moduli, and Poison＇s ratio are also investigated thoroughly. The calculations are carried out on shear moduli and anisotropy factor for cubic TiO2. The Vickers hardness is also tested for fluorite and pyrite cubic-structured TiO2. Furthermore, the results are compared with the previous theoretical and experimental results. It is found that DFT- based simulation produces results which are approximation to experimental results, whereas the calculated elastic constants are better than the previous theoretical and experimental values.

Microalgal bioremediation of food-processing industrial wastewater under mixotrophic conditions： kinetics and scaleup approach

引用

Frontiers of Chemical Science and Engineering 2016年第4期10卷 499-508页

作者： Suvidha Gupta R. A. pandey Sanjay b. Pawar Environmental biotechnology Division CSIR-Nafional Environmental Engineering Research Institute (NEERI) Nagpur 440020 India

The Chlorella microalgae were mixotrophically cultivated in an unsterilized and unfikered raw foodprocessing industrial wastewater. both inorganic carbon （CO2-air） and organic carbon （wastewater） were provided simultaneously for microalgae growth. The aim of the study is to find out the utilization rates of total organic carbon （TOC） and chemical oxygen demand （COD） under mixotrophic conditions for a given waste water. About 90% reduction in TOC and COD were obtained for all dilutions of wastewater. Over 60% of nitrate and 40% of phosphate were consumed by microalgae from concentrated raw wastewater. This study shows that microalgae can use both organic and inorganic sources of carbon in more or less quantity under mixotrophic conditions. The growth of microalgae in food-processing industrial wastewater with all studied dilution factors, viz. zero （raw）, 1.6 （dilution A）, and 5 （dilution b） suggests that the freshwater requirement could be reduced substantially （20%-60%）. The degradation kinetics also suggests that the microalgae cultivation on a high COD wastewater is feasible and scalable.
