*** and context Maximizing the value of distributed energy resources(DERs)on the Australian electricity energy system while also making sure that their widespread uptake does not compromise system stability and reliability is a looming challenge for energy network operators and market *** the absence of a national standard for DER connectivity and third-party external control,equipment manufactured for the DER market,such as residential photovoltaic(PV)inverters and battery storage systems cannot provide optimal value to the energy *** main challenges relate to high penetrations of unmanaged PV systems,which can result in power-quality issues and reverse power flows on local sections of distribution networks;there are also missed opportunities if distributed PV inverter management is considered as a separate issue from load management.

OBJECTIVE: To determine the types of major maternal-perinatal morbidity associated with prolonged, acute-onset severe systolic hypertension during pregnancy and postpartum. METHODS: A medicolegal database retaining only medical record data was created from all cases involving women with medical/hypertensive disorders of pregnancy evaluated by the first author between 1986-2015. Case files of women that experienced severe systolic hypertension (SSH) sustained for many hours to days were identified for study. RESULTS: Sixty six pregnant/postpartum women met study criteria. Stroke secondary to intracranial hemorrhage or thrombosis (65.2) and acute pulmonary edema (33%) were the leading causes of maternal morbidity and mortality, most often antepartum as a component of early-onset preeclampsia (≤34 weeks). Eclampsia, abruptio placenta and injury to heart, liver and/or kidneys were other frequent co-morbidities. Seven postpartum women developed sudden new-onset postpartum SSH and suffered a stroke 4 -

Objective: To review a case series of 12 women with unexpected heart and lung disorders that occurred during pregnancy and the puerperium, describing for teaching purposes the pitfalls in practice and the lessons learned from this experience. Materials & Methods: We reviewed case files of women with medical and/or hypertensive complications of pregnancy that were evaluated for medicolegal defense purposes by the first author between 1986-2015. Twelve women in these case files experienced unexpected cardiovascular and/or cardiopulmonary complications late in pregnancy or early in the puerperium. For each case, the pertinent medical record information was extracted. Important concepts as lessons learned are summarized and referenced for teaching purposes. Results: Five women had undetected preexisting heart disease which acutely deteriorated during the third trimester, four women developed postpartum heart failure related to pregnancy and delivery, and three women suffered an intrapartum cardiac arrest;none survived. Their case presentations illustrate the importance of obstetric health care professionals being alert to the signs/symptoms of developing cardiopulmonary disease late in pregnancy and following delivery so that timely evaluation and intervention can be accomplished to potentially avoid morbidity and mortality. Diagnostic categories include peripartum heart failure, high-risk chronic hypertension, s

OBJECTIVE: HELLP syndrome is a severe preeclampsia spectrum disorder diagnosed when laboratory evidence of hemolysis, liver dysfunction and thrombocytopenia are present. The presence of epigastric pain with laboratory criteria for HELLP syndrome may indicate higher maternal-fetal risk. Thus we explored maternal outcomes in 42 pregnant/postpartum women that had HELLP syndrome by laboratory criteria in addition to sudden severe epigastric pain. METHODS: A database was constructed from the medical files of all patients with medical/hypertensive disorders evaluated by the first author from 1986-2015 for medicolegal purposes. All patient files of women who presented to their physicians with a diagnosis of presumptive HELLP syndrome were examined. RESULTS: Fifty-eight pregnant/postpartum women fulfilled study inclusion criteria;they presented to physicians for evaluation usually in non-tertiary care hospital settings. Clinical presentation and care including lab data and details of pregnancy outcome were evaluated. A correct diagnosis of HELLP syndrome was verified for 42 women (72.4%);others were determined to have AFLP-Acute Fatty Liver of Pregnancy (n

Individuals may reduce competition by temporally partitioning their use of a shared resource. Behavioral differences between sexes in ungulates may encourage segregation as individuals attempt to avoid antagonistic interactions. However, dominant sex and age groups may reduce subordinates' access to food resources, regardless of the subordinate's sex. We hypothesized that white-tailed deer Odocoileus Virginian us temporally segregated at supplemental feedi ng sites based on social rank (subordinate: yearling males and adult females;dominant: adult males) and that segregation was affected by phase of the breeding season and diel cycle. If deer temporally segregate according to social rank, we predicted that the resulting activity patterns would manifest in one social class being relatively more susceptible to hunter-induced mortality. We used a multistate modeling approach to quantify temporal segregation and calculated the probability that a feeding site was in a particular state during diurnal and nocturnal hours for each of the 3 phases of the breeding season. We determined that transition probabilities differed by season and diel cycle and dominant and subordinate social classes clearly avoided each other, with <1% co-occurrenee at feedi ng sites. During the pre-breedi ng seas on, the probability of a subordi nate being present during diurnal hours was *** more likely than a dominant being present, but did not differ during nocturnal hours. There was no difference for dominants and subordinates during diurnal or no cturnal hours during the breedi ng season .In the post-breedi ng season, subordi nates were 1.7x more likely to occur at the feeding site than a dominant during diurnal hours but they did not differ during nocturnal hours. Our results indicate that dominance status influences temporal segregation at feeding sites and is affected by the phase of the breeding season. Therefore, the resulti ng activity patterns may in crease subordi nates' risk to human
