It is also capable to detect dosimetric and geometric errors and therefore it is suitable for monitoring VMAT delivery.Hydrothermal treatment (HT) is a promising method to convert sewage sludge to hydrochar biofuel. The heating value is directly correlated to the carbon content in hydrochar; however, the release of organic matter from sludge to hydrolysate and the transfer of the Maillard reaction products generated in the hydrolysate to the solid phase alter the carbon content in hydrochar. In this study, the relationship between hydrolysate and heating value of sludge-based hydrochar was presented, aiming to explain how the calorific value of hydrochar was affected by HT conditions. We adopted a direct combustion test to verify its clean combustion features. Hydrochar derived at 260 °C and residence time of 4 h (HC 260-4) exhibited the highest calorific value (HHVdaf = 26.23 MJ/kg) with an energy density of 1.43, and its fuel characteristics were similar to those of lignite. The increase in the HT temperature and residence time up to 260 °C and 4 h, respectively, was beneficial for enhancing HHVdaf. Conversely, further incrapplying hydrochar as biofuel. The findings of this study provided a new perspective to explain the heating value generation of hydrochar and more direct evidence to assess its clean combustion properties, with promising perspectives for practical applications.Membrane technologies have been widely applied in water treatment, wastewater reclamation and seawater desalination. Feed spacer present in spiral wound membrane (SWM) modules plays a pivotal role in creating flow channels, promoting fluid mixing and enhancing mass transfer. However, it induces the increase of feed channel pressure (FCP) drop and localized stagnant zones that provokes membrane fouling. For the first time, we comprehensively review the research evolvement on feed spacer in SWM modules for water treatment over the last 20 years, to reveal the impacts of feed spacer on the hydrodynamics and biofouling in the spacer-filled channel, and to discuss the potential approaches and current limitations for the modification of feed spacer. The research process can be divided into three phases, with research focus shifting from hydrodynamics in Phase Ⅰ (the year of 2001-2008), to biofouling in Phase Ⅱ (the year of 2009-2015), and then to novel spacer designs in Phase Ⅲ (the year of 2016-2020). The spacer cformance.

To study long-term outcomes in patients with CNS demyelinating events exposed to TNFa-inhibitors (TNFai), including subsequent clinical relapse, MRI lesions, and use of disease modifying therapy (DMT) for MS.

Adult patients evaluated for a CNS demyelinating disease during TNFai use were identified at Mass General Brigham [01/1998-08/2020] and analyzed in clinically-relevant subgroups. Inclusion criteria required a first neurological event while taking a TNFai, MRI lesions consistent with demyelination, and the absence of a more probable alternative diagnosis.

21 cases (mean age 44years, 20 female, 14≥2 MS risk factors) had an index neurological event (INE) at a median of 12months (range 1-176) from onset of TNFai use (adalimumab in 10, etanercept 6, infliximab 5). MRI lesions were most often present in periventricular (16/20, 80%) and spinal zones (10/20, 50%); 37% (7/19) met ≥ 2 Barkhof criteria at onset. CSF testing was abnormal in 64% (7/11). 67% (10/15) with available follow-up MRIs developed new le

Presence in the neonatal intensive care unit (NICU) is a vital step for caregivers initiating involvement, such as skin-to-skin contact, holding or singing/reading to their newborn. Little is known about caregiver presence and involvement in Canadian NICU's context by caregiver type (mother, father, other), and the association between maternal presence and key maternal and newborn characteristics.

The primary objective was to examine the presence and involvement of family caregivers in the NICU. The secondary objective was to examine the relationship between maternal presence and maternal and newborn characteristics.

A prospective observational cohort study in an open bay setting of an Eastern Canadian NICU. Presence (physically present at the newborn's bedside) and involvement (e.g., skin-to-skin, singing/reading) were tracked daily by families in the NICU until discharge. Demographic information was also collected.

Participants included 142 mothers and their newborns. Mothers were present 8.7 h/day, fathers were present 4.1 h/day, and other caregivers were present 1.8 h/day in the NICU in the first 34 days. Mothers were involved in care activities 50% of the time they were present in the NICU, whereas fathers and other caregivers were spending 20% and 6% of their time respectively. Regression identified maternal age, distance to home, parity, birthweight, and length of stay to be statistically significant variables related to maternal presence.

There is variation in presence and involvement by caregiver type. Targeted interventions to maintain and increase mothers, fathers and other caregivers' presence and involvement in care throughout their stay in the NICU are recommended.

At the initiation of the TAI protocol (Day -9), all cows received a 1.0 g intravaginal P4 insert, 2.0 mg E2 benzoate and received (PGF1) or not (PGF0) 0.5 mg cloprostenol sodium (PGF). On Day -2, the P4 insert was removed, all cows received 0.5 mg PGF, 300 IU equine chorionic gonadotropin (eCG) and 0.5 (EC0.5) or 1.0 mg estradiol cypionate (EC1.0). On Day 0, cows were treated (G1) with 8.4 μg buserelin acetate (GnRH) or not (G0), concurrently with TAI. The eight treatments were generated 1) PGF0-EC0.5-G0 (n = 364), 2) PGF0-EC0.
