A comparison in product‐value potential in four treatment strategies for food waste and faeces – assessing composting, fly larvae composting and anaerobic digestion
Authors: Lalander Cecilia , Nordberg Åke , Vinnerås Björn 
Published: July 2017

AbstractMunicipalities are expected to provide solid waste management, which is funded by tax revenue or/and waste treatment fees. In many low‐ and middle‐income countries, municipalities struggle to provide an adequate level of service, and in these places, the informal sector plays a major role in the collection and treatment of solid waste. In contrast to the plastic and metal fraction, the organic fraction is not managed by the informal sector, primarily because it has low or no financial value and treatment would cost more than the possible revenue. If the organic fraction could be converted to valuable products, the treatment could bear its own cost and this could act as an incentive to collect and treat this fraction. In this study, the potential product value generated through four treatment strategies treating food waste and faeces was compared in a Swedish context: (i) thermophilic composting; (ii) black soldier fly treatment (BSF treatment); (iii) anaerobic digestion (AD); and (iv) BSF treatment followed by AD (BSF + AD). In order to assess the AD strategies, the biomethane potentials of the substrates were assessed. Food waste had the highest biomethane potential, while BSF‐treated faeces had the lowest (417 and 188 NmL g VS−1, respectively). Thermophilic composting yielded the lowest value product (organic fertilizer; 26 € t−1 treated food waste) and BSF treatment + AD the highest total value of products (animal feed, vehicle gas and organic fertilizer; 215 € t−1 treated food waste). The treatment costs were not taken into account here; the total value gives an indication of the cost margin for the different strategies studied. In places with an existing AD plant, BSF treatment + AD strategy is the most economically viable. In places where no such plant exists, BSF treatment is likely to be the most economically favourable treatment.
Did Investors Herd during the Financial Crisis? Evidence from the US Financial Industry
Authors: Humayun Kabir M. 
Published: July 2017

AbstractWe examine the herding behavior of investors in the US financial industry, especially commercial banks, S&Ls, investment and insurance firms during global financial crisis of 2008 towards own sub‐sector and market consensus using augmented cross sectional absolute deviation of returns (CSAD) model. After distinguishing between fundamental and non‐fundamental information, we find a greater influence of global financial crisis on spurious herding for commercial and investment banks, and such herding increases in the down market and with conditional volatility of returns, but adverse herding is prevalent among investors during normal period in response to fundamental information. We also find that herding intensity on fundamental information is relatively high with market consensus for all financial institutions except insurance firms in high volatility regime, and intentional herding is only significant and limited to S&Ls and investment banks in high volatility regime. Our findings suggest limited spillover effects of herding when investors face non‐fundamental information.

ABSTRACTWe present a new surgical modification to allow propeller perforator flaps to cover pressure sores at various locations. We used a propeller perforator flap concept based on the detection of newly formed perforator vessels located 1 cm from the wound margin and stimulated by the chronic inflammation process.Between January 2009 and January 2017, 33 wound edge‐based propeller perforator flaps were used to cover pressure sores at various locations in 28 patients. In four cases more than one flap was used on the same patient. The patients comprised 18 males and 10 females with a mean age of 41·25 (range, 16–70) years.All patients underwent follow‐up for 0–12 months. The mean follow‐up duration was 5·03 months. Venous congestion was observed in three flaps that were rotated by 180° (9·1%). However, there was a significant difference between flaps rotated by 90° and 180° according to the complication rate (P = 0·034). Out of 33 flaps, 29 flaps healed uneventfully. Patients were able to sit and lie on their flaps three weeks after surgery.In our study, we were able to obtain satisfying final results using these novel flaps.

AbstractEffects of quenching process on dielectric, ferroelectric, and piezoelectric properties of 0.71BiFeO3−0.29BaTiO3 ceramics with Mn modification (BF–BT−xmol%Mn) were investigated. The dielectric, ferroelectric, and piezoelectric properties of BF–BT−xmol%Mn were improved by quenching, especially to the BF–BT−0.3 mol%Mn ceramics. The dielectric loss tanδ of quenched BF–BT−0.3 mol%Mn ceramics was only 0.28 at 500°C, which was half of the slow cooling one. Meanwhile, the remnant polarization Pr of quenched BF–BT−0.3 mol%Mn ceramics increased to 21 μC/cm2. It was notable that the piezoelectric constant d33 of quenched BF–BT−0.3 mol%Mn ceramics reached up to 191 pC/N, while the TC was 530°C, showing excellent compatible properties. The BF–BT−xmol%Mn system ceramics showed to obey the Rayleigh law within suitable field regions. The Rayleigh law results indicated that the extrinsic contributions to the dielectric and piezoelectric responses of quenched BF–BT−xmol%Mn ceramics were larger than the unquenched ceramics. These results presented that the quenched BF–BT−xmol%Mn ceramics were promising candidates for high‐temperature piezoelectric devices.

AbstractThe phoswich detectors can determine the location of nuclear interactions with the matrix and it is an effective approach to improve the spatial resolution at the edge of the field of view in positron emission tomography. In this study, we proposed a kind of bilayer structure garnet ceramic scintillators for phoswich detectors. Bilayer Pr:LuAG/Ce:LuAG ceramic scintillations with different thickness ratio were fabricated through solid‐state reaction and vacuum sintering without further cutting or stacking process. The phase, microstructure, fluorescence, and scintillation properties were characterized and studied. The decay time of the Pr:LuAG layer was about 21.8 ns while that of the Ce:LuAG layer was 58.6 ns. Different 5d‐4f emission bands of 290‐450 and 475‐700 nm were observed in the Pr:LuAG layer and Ce:LuAG layer, respectively. These two features meet the basic requirements of phoswich detectors. Separation of interactions with γ‐ray in different layers has achieved in the pulse height spectra. These properties reveal that this kind of multilayer structure garnet ceramic scintillators have potential application value in the field of phoswich detectors.
Boosting the photovoltaic performance of Zn2SnO4‐based dye‐sensitized solar cells by Si doping into Zn2SnO4
Authors: Asemi Morteza , Ghanaatshoar Majid 
Published: July 2017

AbstractIn the present work, Zn2SnO4 nanoparticles were doped with silicon to improve their electrical and optical properties by the conventional solid‐state reaction method. The results showed that the minimum electrical resistivity of about 0.09 Ωcm was obtained for Zn2SnO4 nanoparticles with 3% Si doping. The decrease in the electrical resistivity can be attributed to the insertion of Si+4 atoms into the Zn+2 and/or Sn+4 sites and also the formation of more oxygen vacancies in the Zn2SnO4 lattice. The formation of the more oxygen vacancy defect states in Si‐doped Zn2SnO4 nanoparticles was verified by photoluminescence spectroscopy. The efficiency of a dye‐sensitized solar cell based on 3% Si‐doped Zn2SnO4 was significantly better, by about 81%, compared to that of a cell based on the undoped Zn2SnO4. The enhancement in the efficiency can be ascribed to the facilitation of electron transport throughout a photoelectrode due to increase in the charge carrier concentration which was caused by Si doping.

AbstractEnvironmental factors that influence flight activity of Diaphorina citri Kuwayama (Hemiptera: Liviidae) may have implications for Huanglongbing spread and management. In this work, four studies were conducted to evaluate the effect of environmental conditions on D. citri take‐off. In the first, insects were transferred to sweet orange seedlings and confined inside an acrylic cage to verify the take‐off periodicity and the effect of environmental factors on this process. In the second, take‐off temperature threshold was estimated by recording the number of insects that initiated flight from a platform when subjected to gradual temperature increases from 15 to 39°C. In the other studies, we evaluated the effect of different photoperiods and temperature regimes (third study) and of constant temperatures (fourth study) on the propensity for D. citri flight. Insects were confined in clear plastic bottle cages with tubes of 50 ml placed on the cab, to collect emerged adults that initiated flights. Results showed that a small portion of the tested population (maximum 10%) tends to take off from plants and this behaviour is more prevalent in the afternoon (14:00–16:00 h), coinciding with daytimes of lower humidity and higher thermal amplitude. Adults that were submitted to lower temperatures (18°C) and short light periods (10 h) showed less propensity to flight. In contrast, at constant 27°C, the insects were more prone to flight, and this result was confirmed when individuals were submitted to increases in temperature, indicating that 27.14°C is the take‐off temperature threshold of D. citri. Results show that temperature plays an important role in the flight activity of D. citri and suggest that control measures of the insect may be more effective in the morning and in temperatures below 27°C, when the probability to take off from a host is lower.

AbstractThe assessment of autism in individuals with mild intellectual disabilities (MID) is complicated because of the overlap between autistic traits and intellectual limitations. Impaired social emotional reciprocity is a core diagnostic criterion for autism. However, it is unknown whether reciprocal behaviour differs between MID individuals with or without an autism spectrum disorder (ASD). This study explored differences in reciprocal behaviour of 35 children and adolescents with MID (intelligence quotient 50–85): 15 with ASD (ASD‐MID) and 20 with typical development (TD‐MID) using the Interactive Drawing Test (IDT). ASD‐MID participants showed a lower quality of reciprocal behaviour compared with TD‐MID participants. The difference in quality of reciprocal behaviour between ASD‐MID and TD‐MID participants was not significantly related with Peabody Picture Vocabulary Test scores and thus not attributable to verbal capacity. The IDT is likely to reflect the child's inclination to display reciprocal behaviour in everyday situations, as its scale scores were meaningfully associated with the level of social cognition assessed with the Social Responsiveness Scale. Thus, the IDT seems well suited for measuring impairments in reciprocal behaviour in children and adolescents with MID.

AbstractInfective endocarditis (IE) during pregnancy is a rare but serious condition. Cardiopulmonary bypass during pregnancy has a high rate of fetal morbidity and mortality. We here report the case of a 22‐year‐old pregnant woman with confirmed IE. Multiple large cardiac valve vegetations, severe aortic valve regurgitation, and hemodynamic compromise were observed. With full implementation of fetal monitoring and protection strategies, open heart surgery was performed at 31.4 weeks’ gestation to aid survival, followed by an elective cesarean delivery at 34.4 weeks. As of the 3‐month follow‐up, both the mother and infant were in good health. This shows that a fetus can survive maternal thoracotomy under cardiopulmonary bypass with proper perioperative management, which means that this technique does not need to be excluded from consideration in the treatment of IE complicating pregnancy.

AbstractAimTo examine the effect that human papillomavirus (HPV) vaccination has had in Akita Prefecture, by comparing cervical cytology results from women aged 20–24 years with or without HPV vaccination.MethodsWe examined cervical cytology results from 2425 subjects who underwent cervical cancer screening under the jurisdiction of the Akita Foundation for Healthcare between January 2014 and October 2016. We compared the prevalence of cytologic abnormalities among women aged 20–24 years with or without HPV vaccination.ResultsThe rate of atypical squamous cells of undetermined significance (ASC‐US) or worse was 0.242% (1/413) with HPV vaccination, and 2.04% (41/2012) without HPV vaccination. Overall, the prevalence of abnormal cytology results was significantly lower in women aged 20–24 years who had received an HPV vaccination than in those who had not (P = 0.011). The reduction in the rate of abnormal cervical cytology results by HPV vaccination was 88.1%.ConclusionWithin a 4‐year–5‐year period following vaccination, women aged 20–24 years who received an HPV vaccination had significantly lower rates of abnormal cervical cytology results than those who did not receive the vaccine.

AbstractAimTo compare the therapeutic effect of 1.88‐mg and 3.75‐mg gonadotrophin‐releasing hormone agonist (GnRHa) in the treatment of stage III–IV endometriosis after laparoscopic surgery.MethodsFifty patients with stage III–IV endometriosis diagnosed on laparoscopy were randomized into two groups according to GnRHa dose. Sex hormone level, symptoms of estrogen deficiency and lumbar vertebrae bone density were compared and analyzed between the two groups.ResultsBone density was decreased in both groups at 20 weeks after treatment, and the degree of bone density loss in the full‐dose group (5.6%) was higher than in the half‐dose group (1.2%; P < 0.05). Surgery combined with the 3.75‐mg GnRHa or with the 1.88‐mg GnRHa relieved the degree of dysmenorrhea, although one case of light dysmenorrhea occurred in each group, but there was no significant difference (P > 0.05) after resumption of menstruation. Both groups had symptoms of perimenopause at 8 weeks after treatment (P > 0.05), but change in Kupperman score with time differed between the groups. At 16, 20 weeks after treatment, the symptoms of perimenopause in the half‐dose group were improved, and Kupperman score was lower than at 8 weeks after treatment. In the full‐dose group, however, Kupperman score was higher than at 8 weeks after treatment and higher than in the half‐dose group (P < 0.05). After treatment, follicle‐stimulating hormone and luteinizing hormone both decreased in both groups (P < 0.05), but there was no difference between the two groups (P > 0.05). Estradiol (E2) in the full‐dose group was significantly lower than in the half‐dose group (P < 0.05).ConclusionThe 1.88‐mg GnRHa treatment can be used in III–IV endometriosis patients after laparoscopic surgery, to reduce perimenopausal symptoms, significantly improve bone loss, and achieve a good clinical effect.

AbstractAimOur aim was to investigate the effect of the prophylactic use of vaginal progesterone on the latency period from the initiation of tocolytic therapy to delivery in twin pregnancies with preterm labor.MethodsThis study was a secondary analysis of a randomized, double‐blind, placebo‐controlled trial of twin pregnancies in mothers who were exposed to a 200 mg vaginal progesterone ovule or a placebo ovule daily from 18 to 34 weeks gestation. Patients who were administered tocolysis with Atosiban because of preterm labor were included. The latency from tocolysis to delivery, mean gestational age at delivery and the rates of delivery within 48 h and within seven days were compared between progesterone and placebo groups.ResultsThe analysis included 27 women in the progesterone group and 30 in the placebo group. The baseline characteristics were similar between the groups. Overall, there were no differences in the latency period to delivery (17.54 ± 13.54 days and 21.58 ± 13.52 days; P = 0.289), rates of delivery within 48 h (14.8% and 6.7%; P = 0.40) or within seven days (29.64% and 23.3%; P = 0.76) or mean gestational age at delivery (32.53 ± 3.33 and 34.13 ± 2.87; P = 0.08) between the progesterone and placebo groups, respectively.ConclusionsProphylactic use of 200 mg of vaginal progesterone does not influence the latency to delivery in women with twin pregnancies treated with tocolysis because of preterm labor.

ObjectiveThis study investigated the risk factors of ketamine associated‐lower urinary tract symptoms (LUTS), such as duration of use, dosage of ketamine, co‐occurring substance use of other psychoactive drugs, comorbidities, and depression.MethodsThis study was a cross‐sectional survey. LUTS was assessed with the O'Leary symptom and problem index (OSPI) scores. We included the comorbidities of interstitial cystitis/painful bladder syndrome (IC/PBS) as comorbid factors. Depression was evaluated based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5). Duration of use, dosage of ketamine and the OSPI scores were subjected to log transformation because of the skewed distribution.ResultAmong 143 participating ketamine users, 25 (17.5%) had LUTS. Duration of ketamine use was significantly positively correlated with OSPI scores (adjusted β [95% CI], 0.21 [0.06–0.35] in log‐log model), which equaled a 10% increase in months of ketamine‐use increased OSPI scores by 2.02 %. Female and depression were significantly associated OSPI scores (adjusted β [95% CI], 0.20 [0.03–0.37], 0.49 [0.29–0.70], respectively in the log‐linear model), with OSPI scores being 1.22 times higher in female, and 1.63 times higher in ketamine users with depression. Dosage of use was not significantly associated with OSPI scores (adjusted β [95% CI], 0.04 [−0.12 to 0.20], P = 0.64 in log‐log model), likewise with comorbid diseases (adjusted β [95% CI], 0.07 [−0.08 to 0.21], P = 0.36 in log‐linear model).ConclusionDepression and longer duration of exposure to ketamine are significantly associated with the development of LUTS among ketamine users. Early evaluation and intervention of depression should be considered in patients of ketamine‐associated LUTS.

ObjectivesWe investigated the effect of daily climatic parameters on spontaneous acute urinary retention (sAUR) and evaluated the risk factors for refractory/recurrent AUR.MethodsA total of 4194 patients older than 40 years were diagnosed with AUR in the emergency department at Gangnam Severance Hospital, Seoul, from January 2007 to May 2016. To evaluate climatic parameters at sAUR onset, we included individuals living in the area around the hospital. We excluded patients with fever, who did not return to the hospital after the AUR episode or with AUR occurring within 2 weeks following admission for surgery or chemotherapy.ResultsAmong 818 patients living in the two districts around the hospital, winter and October had the highest seasonal and monthly rates of sAUR development, respectively, and sAUR incidence increased with age. Daily temperature range and mean wind speed were significant risk factors for sAUR development. Several daily climatic parameters had seasonal effects on sAUR incidence. Over a mean follow‐up of 0.98 years, 122 patients (14.9%) developed refractory/recurrent AUR. Transitional zone index (TZI; HR = 1.03; P = 0.002) and prostate‐specific antigen (PSA) at the time of sAUR (HR = 1.01; P = 0.030) were significant predictors of refractory/recurrent AUR. Benign prostate hyperplasia medication and transurethral prostatectomy after sAUR were not risk factors for refractory/recurrent AUR.ConclusionsCold temperature provoked sAUR in patients with higher age and International Prostate Symptom Score. Patients with higher TZI and PSA level at the time of sAUR had a greater risk of developing refractory/recurrent AUR.
