Observations on regeneration of the pedipalp and legs of scorpions
Get PDFAn Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated section of the metatarsus. This supports previous observations that scorpions can only regenerate the pretarsus of the leg, again irrespective of where on the limb the original breakage occurred
Flexible Dye-Sensitized Solar Cells Assisted with Lead-Free Perovskite Halide
Get PDFDye-sensitized solar cells (DSSCs) have shown promising alternative to Si-based counterparts due to low-cost, abundant raw materials, and non-vacuum processing. Here, we report a solution-based process to create flexible DSSCs on aluminum foils. Mesoporous TiO2 electrode was directly deposited on Al foil through spin casting. After post-thermal annealing, the resultant samples render optical smooth, crack-free, and large nanocrystalline thin films. The as-prepared double-layer porous TiO2 thin film was incorporated with a porphyrin dye followed by a perovskite halide salt Cs2SnI6, as the hole transport material, replacing liquid electrolyte. A transparent conducting plastic sheet was used as the cathodic electrode to complete the solar cell construction. Samples were characterized using X-ray diffraction, SEM, AFM, UV–Vis spectrometer, and current–voltage measurements. A photo-electricity conversion efficiency of 3.74% has been achieved that potentially makes the possibility of scaling up fabrication of all-solid-state flexible solar cells

Environmental Toxicology
No full textThis open online textbook on Environmental Toxicology aims at covering the field in its full width/ including aspects of environmental chemistry/ ecotoxicology/ toxicology and risk assessment. With that/ it will contribute to improving the quality/ continuity and transparency of the education in environmental toxicology. We also want to make sure that fundamental insights on fate and effects of chemicals gained in the past are combined with recent approaches of effect assessment and molecular analysis of mechanisms causing toxicity. The book consists of six chapters/ with each chapter being divided into several sub-chapters to enable covering all aspects relevant to the topic. All chapters are designed in a modular way/ which each module having clear training goals and being flagged with a number of keywords. Most modules have an average length of 1000-2000 words/ a limited number of references/ and 3-5 figures and/or tables. A few modules are enlighted with short clips/ animations or movies to allow better illustration of the theory. The introduction chapter of the book/ for instance/ contains a short interview with two key experts reflecting on the development of the field over the past 30 years. The book contains tools for self-study and training/ like a (limited) number of questions at the end of each module. For the future we foresee the addition of separate exercises and other tools that may help the student in understanding the theory.https://mds.marshall.edu/oa-textbooks/1820/thumbnail.jp
Digging into Archaeology: A Brief OER Introduction to Archaeology with Activities
No full textThis book is intended for use in a variety of introductory archaeology settings/ such as in lectures and lab courses. This text can complement an existing traditional text or completely replace a standard text. It can be used for its activities or as a study resource. When we wrote this text/ we designed the chapters to be brief/ providing concise and to-the-point information. This book is not intended to replace lectures or direct instruction from an instructor; rather/ it supports learning in a variety of settings and formats. The book can be printed in whole/ read digitally/ or used piecemeal in either format. However you use this text/ we hope that you find it serves as an instructive learning tool and that you dig archaeology as much as we do!https://mds.marshall.edu/oa-textbooks/1821/thumbnail.jp
A Scrutiny of Mental Illness in Criminality and the Assessment of Viable Alternatives
Get PDFBecause of the compelling role it plays as an enigma, mental illness has been featured in innumerable theaters of human history and our present-day society. There is perhaps no greater place for this dynamic than our criminal justice system. This analysis provides a thorough examination of how our modern approach to the management of mental illness evolved in accordance to the ways in which it began. The controversy over incarceration rates of the mentally ill are astronomical, in that nearly half of inmates in the United States are suffering with a mental illness of sorts (National Alliance for the Mentally Ill, n.d.a). Within is a discussion of whether these rates are appropriate; that is, whether there is a clear link between mental illness and criminal behavior that justifies that percentage. The main policy implication that has been suggested by medical professionals and scholars alike to combat these figures is multiple forms of medicinal and cognitive therapies, as well as stringent substance abuse treatments
Embryonal Rhabdomyosarcoma in the Pelvis of a 22-Year-Old Female: A Case Report
Get PDFEmbryonal rhabdomyosarcoma is a rare soft-tissue sarcoma that is responsible for less than 1% of malignancies in the adult population. We present a case of a 22-year-old female with a six-month history of abnormal uterine bleeding that was found to have an exophytic mass within the cervix. Magnetic resonance imaging was performed and revealed a large pelvic mass. Further workup included biopsies and surgical removal of the tumor, leading to the diagnosis of embryonal rhabdomyosarcoma. PET scan showed no FDG-avid malignancy, aiding in the decision-making process for adjuvant treatment to include vincristine, actinomycin D, cyclophosphamide, and mesna. This case is important to document due to the rarity of this disease and to serve as a reminder to gynecologists to consider the addition of rhabdomyosarcoma in the differential diagnosis when evaluating young adult females presenting with abnormal uterine bleeding and a cervical mass lesion
