Factors Influencing Household Outdoor Residential Water Use Decisions in Suburban Boston (USA)

Water withdrawals for human use can reduce water in lakes and streams, with significant consequences for aquatic biota. Urbanization, particularly large lawn areas associated with low-density residential development, increases demand on freshwater resources. Outdoor water use accounts for the largest proportion of residential water use during the summer months, which corresponds to the lowest water levels in freshwater ecosystems. Prior studies have sought to understand property features associated with the highest water use; however, these studies do not consider other types of water use nor do they capture the decisions by residents that result in outdoor water use. Understanding these decisions is critical for developing policies and education tools that reduce outdoor water use by changing people’s water use behavior. Focusing on the Ipswich River Watershed, which has been impacted by extreme low flows due to water withdrawals, a mixed-methods approach was used to understand residents’ outdoor water use and the factors influencing the amount and timing of water use. To quantify water use meters were placed on outdoor spigots at residences, participants were provided with a written survey before and after water metering, and in-person interviews were conducted. Irrigation systems used the most water; however, garden watering occurred as frequently as lawn irrigation and many participants indicated that their garden was a primary factor in water use decisions. Participants’ water use decisions fell into categories from habitual (i.e., watering at the same time of day) to purely cognitive (i.e., watering based on weather and plant needs). While many participants felt that water conservation was necessary, their willingness to implement landscape-level conservation practices, such as rain barrels, did not differ from participants who believed water conservation was unnecessary. Interestingly, many residents reduced their outdoor water use behavior and increased their concern for other environmental issues in response to study participation. To have the greatest impact on overall water use, efforts should focus on residents running irrigation systems on a schedule. Outreach should emphasize individualized approaches to water conservation, regardless of water source (public or private), and include information and conservation options specific to the water needs of the individual property

Determination of propofol by GC/MS and fast GC/MS-TOF in two cases of poisoning

Two cases of suspected acute and lethal intoxication caused by propofol were delivered by the judicial authority to the Department of Sciences for Health Promotion and Mother-Child Care in Palermo, Sicily. In the first case a female nurse was found in a hotel room, where she lived with her mother; four 10 mg/mL vials and two 20 mg/mL vials of propofol were found near the decedent along with syringes and needles. In the second case a male nurse was found in the operating room of a hospital, along with a used syringe. In both cases a preliminary systematic and toxicological analysis indicated the presence of propofol in the blood and urine. As a result, a method for the quantitative determination of propofol in biological fluids was optimized and validated using a liquid-liquid extraction protocol followed by GC/MS and fast GC/MS-TOF. In the first case, the concentration of propofol in blood was determined to be 8.1 \u3bcg/mL while the concentration of propofol in the second case was calculated at 1.2 \u3bcg/mL. Additionally, the tissue distribution of propofol was determined for both cases. Brain and liver concentrations of propofol were, respectively, 31.1 and 52.2 \u3bcg/g in Case 1 and 4.7 and 49.1 \u3bcg/g in Case 2. Data emerging from the autopsy findings, histopathological exams as well as the toxicological results aided in establishing that the deaths were due to poisoning, however, the manner of death in each were different: homicide in Case 1 and suicide in Case 2

GHB: farmaco, sostanza d’abuso e droga da stupro: diverse tipologie di uso, differenti problematiche analitico-forensi

L’acido gamma-idrossibutirrico (GHB) è un neurotrasmettitore con effetti gaba-mimetici; si tratta di un composto endogeno, ma notoriamente usato per le applicazioni terapeutiche come anestetico per via endovenosa, come sedativo e per il trattamento della narcolessia. Dagli anni ‘80 è comune sostanza usata come doping, quindi emerge come droga da “tempo libero” nei rave-party; più recentemente, i supposti effetti afrodisiaci e la reale capacità di induzione di amnesia retrograda ne hanno indotto l’utilizzazione quale sostanza in grado di ridurre la capacità di resistenza della vittima di uno stupro annoverandola tra le cosiddette “date rape drugs” (Drug facilitated sexual assault, DFSA), e cioè sostanze psicoattive usate per lo stupro cosiddetto “dopo appuntamento”1. Nel presente contributo si riporta l’approccio metodologico relativamente a due differenti scenari di interesse forense: l’abuso del GHB con quadro di dipendenza patologica e l’uso del GHB come droga da stupro; gli Autori illustrano le modalità di indagine per determinare il GHB nelle differenti matrici biologiche. Conclusioni: gli scenari d’abuso qui presentati rafforzano il concetto che l’analitica tossicologica rivolta alla determinazione del GHB, per tutte le evenienze riguardanti l’uso/abuso e le possibili implicazioni legali, deve realizzarsi secondo canoni analitici convalidati

SKA studies of nearby galaxies : star-formation, accretion processes and molecular gas across all environments

Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike LicenceThe SKA will be a transformational instrument in the study of our local Universe. In particular, by virtue of its high sensitivity (both to point sources and diffuse low surface brightness emission), angular resolution and the frequency ranges covered, the SKA will undertake a very wide range of astrophysical research in the field of nearby galaxies. By surveying vast numbers of nearby galaxies of all types with $\mu$Jy sensitivity and sub-arcsecond angular resolutions at radio wavelengths, the SKA will provide the cornerstone of our understanding of star-formation and accretion activity in the local Universe. In this chapter we outline the key continuum and molecular line science areas where the SKA, both during phase-1 and when it becomes the full SKA, will have a significant scientific impact.Peer reviewedFinal Published versio

GENERALISED INTEGRATION OF SOLID WASTE TREATMENT PRACTICES TO ENHANCE METHANE PRODUCTIVITY, GENERATE SUSPENSION FERTILISER AND UPGRADE BIOGAS

This paper presents a general solution of how to link together the treatment of different solid waste: excess sludge, wastes glycerol or fishery residues and waste ash. The aim of the solution is to enhance biogas production and to produce an organic–mineral suspension fertiliser. The enhancement of biogas productivity is achieved by adding waste glycerol from biofuel plants or fish residues from fish farming and fishing industries into anaerobic reactors of wastewater treatment plants. The enhancement of biogas productivity lies in the range of 200–400%. The fertiliser is produced as a mixture suspension on the basis of waste sludge, waste ash and mineral fertilisers. The mixture is treated by mechanical disintegration, which is responsible for homogenisation and dehelminthing. If the pH of the suspension fertiliser must be reduced, the bubbling of biogas through the suspension can be used. The carbon dioxide content is diminished and the calorific value of the biogas is elevated

Medico legal procedures related to sexual assault: a 10-year retrospective experience of a Daphne protocol application

Background: Sexual assault is a worldwide problem that has not yet been sufficiently acknowledged as confirmed by the literature. Italian law n.96, 1996, foreseeing norms regarding rape and sexual abuse, finally gave significant relevance to sex crimes. In 2004, the European Commission for Justice Internal Affairs and Social Politics promoted the Daphne II program to support victims of rape and abuse, and the Violence and Operative Healthcare Networks (Ve.R.S.O.) project started at the Policlinico \ue2\u80\u9cP. Giaccone\ue2\u80\u9d University Hospital of Palermo in 2006. Aim: data analysis emerging from 10 years experience of Daphne protocol utilization for the management of sexual assault victims. Methods: From October 2006 since December 2016 a total of 90 victims of sexual assault were retrospectively investigated. Patients are divided into groups in relation to: gender, age, place of SA, number and type of assailant, nature of sexual assault, presence/absence of physical or genital injuries. Results: Among victims 88 were females (97%) and 2 males (3%); 68 Italians (75.5%) and 22 foreigners (24.5%). At the time the events occurred, 42% (n = 38) of the victims were minors aged less than 16\uc2 years. In 11 cases, the age of the victim is not indicated. The assailant was an acquaintance of the victim in 65% of the cases (in 73% of these cases, the assailant was a family member). In 26 cases (28%) happened indoor, 44 cases happened outdoor and in 20 cases there were no data. Evidence of recent acute general body trauma (abrasions, bruises, lacerations) was found in 38 cases (42%); other types of injuries include: genital trauma (14 cases, 15%), genital and body traumas (49 cases, 54%) (tab. 1\ue2\u80\u932-). In 24 cases (26%) there were no injuries. Among genital trauma, we distinguished vulvo-vaginal lesions (68.5%) and anal lesions (31.5%). We have classified the minor victims using first Adam\ue2\u80\u99s classification and based on Adam\ue2\u80\u99s classification revised in 2015. Conclusion: Application of the Ve.R.S.O project protocol changed and greatly improved health management of victims of violence. By following these procedures, violence and abuse are analyzed from every point of view, also for an appropriate assessment of the medium and long term health consequences of sexual assault. Only in this way are citizens provided with a high level of protection against gender violence, psychological support and prevention from any form of violence which takes place in respect of such vulnerable people

Forensic tools for the diagnosis of electrocution death: Case study and literature review

Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation. The effects of electric current flow were also highlighted by perforations of endothelial surface of a pulmonary artery using scanning electron microscope, and all the results were analysed by the main tools suggested in the literature

Case Report: Unusual Clinical Presentation of a Rare Cardiac Inflammatory Myofibroblastic Tumor in Children: The Differential Diagnosis With Pediatric Emergencies

Introduction: There are still no guidelines about pediatric cardiac cancers. The purpose of this work is to provide new scientific data facilitating the differential diagnosis of a rare cardiac tumor with an unusual presentation, such as the cardiac inflammatory myofibroblastic tumor (IMT). Case Presentation: A 3-year-old male child presented with several symptoms including unconsciousness, vomiting, and drowsiness. A clinical and neurological examination revealed a unilateral (right) motor delay and positive unilateral Babinski sign. Electrocardiogram (ECG) was normal. Diagnostic Assessment: The total body computed tomography (CT) scans showed hypodensity in the left temporal\u2013parietal lobe, a large hypodense area in the right frontal lobe, and a second area in the left frontal lobe were found with head CT. A magnetic resonance (MR) also noted cerebral areas of hypointensity. The echocardiographic images revealed an ovoid mass, adherent to the anterolateral papillary muscle. The histological exams, performed with hematoxylin\u2013eosin, Masson's trichrome, Alcian blue PAS, Weigert and Van-Gieson stain, allowed observing the microscopic structure of the neoplastic mass. The immunohistochemical analysis was performed through subsequent antibodies: anti-vimentin, anti-actina, anti-ALK, anti-CD8, anti-CD3, anti-CD20, anti-kappa and lambda chains, and anti CD68 antibodies. The healthcare professionals diagnosed a cardiac IMT with brain embolism. Differential Diagnosis: The ventricular localization, observed through radiological exams, required a differential diagnosis with fibroma and rhabdomyoma, the presence of brain embolism with sarcoma, and its morphology with fibroma. Neurological symptoms might be attributed to encephalitis, primitive cerebral cancer, such as astrocytoma or neuroblastoma, cerebral metastases due to any malignancy, or embolic stroke. Conclusion: New studies are encouraged to better define IMT behavior and draw up guidelines confirming the crucial role of multidisciplinary approach and treatment protocol selected on the basis of the characteristics of the tumors, in the case of this rare type of cancer

A Novel Approach by SPME-GC/MS for the Determination of gammahydroxybutyric acid (GHB) in Urine Samples after Conversion into gamma-butyrolactone (GBL)

The quantitative determination of gamma-hydroxybutyric acid (GHB) in urine samples is very important to assess illicit intake or administration. To this end we evaluated several analytical methods: headspace gas-chromatography coupled to flame ionization detection (HS-GC/FID), headspace gas-chromatography coupled to mass spectrometry (HS-GC/MS), headspace gas-chromatography coupled to solid phase microextraction and mass spectrometry (HS-SPME-GC/MS). All these methods were endowed with a not sufficient sensitivity, and then we moved to solid phase microextraction coupled to gas-chromatography with mass spectrometry detection (SPME-GC/MS). At first, GHB was extracted from urine with an organic solvent and analyzed after derivatization. Under these conditions, however, there was a partial overlapping between the chromatographic peak of GHB and that of urea, also extracted by the organic solvent. Then we decided to change analytical approach and to convert GHB to gamma-butyrolactone (GBL), which is not an endogenous compound. A SPME method was optimized and validated for the determination of GBL. The limit of detection (LOD) of the method resulted to be 0.25 \u3bcg/mL for GBL, corresponding to 0.5 \u3bcg/mL for GHB. The lower limit of quantification (LLOQ) was 0.4 \u3bcg/mL for GBL and 0.8 \u3bcg/mL for GHB. The LLOQ of the method resulted 10 times lower than the endogenous level, thus allowing to distinguish between physiological conditions and exogenous assumption

A Hard X-ray Study of the Normal Star-Forming Galaxy M83 with NuSTAR

We present results from sensitive, multi-epoch NuSTAR observations of the late-type star-forming galaxy M83 (d=4.6 Mpc), which is the first investigation to spatially resolve the hard (E>10 keV) X-ray emission of this galaxy. The nuclear region and ~ 20 off-nuclear point sources, including a previously discovered ultraluminous X-ray (ULX) source, are detected in our NuSTAR observations. The X-ray hardnesses and luminosities of the majority of the point sources are consistent with hard X-ray sources resolved in the starburst galaxy NGC 253. We infer that the hard X-ray emission is most likely dominated by intermediate accretion state black hole binaries and neutron star low-mass X-ray binaries (Z-sources). We construct the X-ray binary luminosity function (XLF) in the NuSTAR band for an extragalactic environment for the first time. The M83 XLF has a steeper XLF than the X-ray binary XLF in NGC 253, consistent with previous measurements by Chandra at softer X-ray energies. The NuSTAR integrated galaxy spectrum of M83 drops quickly above 10 keV, which is also seen in the starburst galaxies NGC253, NGC 3310 and NGC 3256. The NuSTAR observations constrain any AGN to be either highly obscured or to have an extremely low luminosity of $_{\sim}^<$10$^{38}$ erg/s (10-30 keV), implying it is emitting at a very low Eddington ratio. An X-ray point source consistent with the location of the nuclear star cluster with an X-ray luminosity of a few times 10$^{38}$ erg/s may be a low-luminosity AGN but is more consistent with being an X-ray binary.Comment: Accepted for publication in ApJ (25 pages, 17 figures
