On the Structure–Property Relationships of Cation‐Exchanged ZK‐5 Zeolites for CO2 Adsorption
Authors: Pham Trong D. , Hudson Matthew R. , Brown Craig M. , Lobo Raul F. 
Published: January 2017

AbstractThe CO2 adsorption properties of cation‐exchanged Li‐, Na‐, K‐, and Mg‐ZK‐5 zeolites were correlated to the molecular structures determined by Rietveld refinements of synchrotron powder X‐ray diffraction patterns. Li‐, K‐, and Na‐ZK‐5 all exhibited high isosteric heats of adsorption (Qst) at low CO2 coverage, with Na‐ZK‐5 having the highest Qst (ca. 49 kJ mol−1). Mg2+ was located at the center of the zeolite hexagonal prism with the cation inaccessible to CO2, leading to a much lower Qst (ca. 30 kJ mol−1) and lower overall uptake capacity. Multiple CO2 adsorption sites were identified at a given CO2 loading amount for all four cation‐exchanged ZK‐5 adsorbents. Site A at the flat eight‐membered ring windows and site B/B* in the γ‐cages were the primary adsorption sites in Li‐ and Na‐ZK‐5 zeolites. Relatively strong dual‐cation adsorption sites contributed significantly to an enhanced electrostatic interaction for CO2 in all ZK‐5 samples. This interaction gives rise to a migration of Li+ and Mg2+ cations from their original locations at the center of the hexagonal prisms toward the α‐cages, in which they interact more strongly with the adsorbed CO2.
Energy‐aware cross‐layer resource allocation in mobile cloud
Authors: Chunlin Li , Yanpei Liu , Youlong Luo 
Published: January 2017

SummaryThis paper proposed an energy‐aware cross‐layer mobile cloud resource allocation approach. In this paper, a hybrid cloud architecture is adopted for provisioning mobile service to mobile device users, which include nearby local cloud and remote public cloud. The computation‐intensive tasks can be processed by the remote public cloud, while the delay‐sensitive computation can be processed by the nearby local cloud. On the basis of the system context and mobile user preferences, the energy‐aware cross‐layer mobile cloud resource allocation approach can optimize the consumption of cloud resource and system performance. The cooperation and collaboration among local cloud agent, public cloud supplier, and mobile cloud user are regulated through the economic approach. The energy‐aware cross‐layer mobile cloud resource allocation is performed on the local cloud level and the public cloud level, which comprehensively considers the benefits of all participants. The energy‐aware cross‐layer mobile cloud resource allocation algorithm is proposed, which is evaluated in the experiment environment, and comparison results and analysis are discussed.
Adjustable vertical vibration isolator with a variable ellipse curve mechanism
Authors: Asai Takehiko , Araki Yoshikazu , Kimura Kosuke , Masui Takeshi 
Published: January 2017

SummaryThis paper presents a passive vertical quasi‐zero‐stiffness vibration isolator intended for relatively small objects. The present isolator has features of compactness, long stroke, and adjustability to various load capabilities. To realize these features, we use constant‐force springs, which sustain constant load regardless of their elongation, and propose a variable ellipse curve mechanism that is inspired by the principle of ellipsographs. The variable ellipse curve mechanism can convert the restoring force of the horizontally placed constant‐force springs to the vertical restoring force of the vibration isolator. At the same time as converting the direction, the vertical restoring force can be adjusted by changing the ratio of the semi‐minor axis to the semi‐major one of the ellipse. In this study, a prototype of a class of quasi‐zero‐stiffness vibration isolator with the proposed variable ellipse curve mechanism is created. Shaking table tests are performed to demonstrate the efficacy of the present mechanism, where the prototype is subjected to various sinusoidal and earthquake ground motions. It is demonstrated through the shaking table tests that the prototype can reduce the response acceleration within the same specified tolerance even when the mass of the vibration isolated object is changed.

The concept of travelling bedload and its consequences for bedload computation in mountain streams
Authors: Piton Guillaume , Recking Alain 
Published: January 2017

AbstractIn bedload transport modelling, it is usually presumed that transported material is fed by the bed itself. This may not be true in some mountain streams where the bed can be very coarse and immobile for the majority of common floods, whereas a finer material, supplied by bed‐external sources, is efficiently transported during floods, with marginal morphological activities. This transport mode was introduced in an earlier paper as ‘travelling bedload’. It could be considered an extension of the washload concept of suspension, applied to bedload transport in high‐energy, heavily armoured streams. Since this fine material is poorly represented in the bed surface, standard surface‐based approaches are likely to strongly underestimate the true transport in such streams. This paper proposes a simple method to account for travelling bedload in bedload transport estimations. The method is tested on published datasets and on a typical Alpine stream, the Roize (Voreppe, France). The results, particularly on active streams that experience greater transport than expected from the grain sizes of their bed material, reinforce the necessity of accounting for the ‘travelling bedload concept’ in bedload computation. The method relevance is discussed regarding varying flood magnitudes, geomorphic responses and eventual anthropic origin of the ‘travelling bedload’ phenomena. To conclude, this paper considers how to compute bedload transport for a wide range of situations, ranging from sediment‐starved cases to the general mobile bed alluvial case, including the intermediate situation of external source supply on armoured bed.

Addressing reverse inference in psychiatric neuroimaging: Meta‐analyses of task‐related brain activation in common mental disorders

Published: January 2017

AbstractFunctional magnetic resonance imaging (fMRI) studies in psychiatry use various tasks to identify case‐control differences in the patterns of task‐related brain activation. Differently activated regions are often ascribed disorder‐specific functions in an attempt to link disease expression and brain function. We undertook a systematic meta‐analysis of data from task‐fMRI studies to examine the effect of diagnosis and study design on the spatial distribution and direction of case‐control differences on brain activation. We mapped to atlas regions coordinates of case‐control differences derived from 537 task‐fMRI studies in schizophrenia, bipolar disorder, major depressive disorder, anxiety disorders, and obsessive compulsive disorder comprising observations derived from 21,427 participants. The fMRI tasks were classified according to the Research Domain Criteria (RDoC). We investigated whether diagnosis, RDoC domain or construct and use of regions‐of‐interest or whole‐brain analyses influenced the neuroanatomical pattern of results. When considering all primary studies, we found an effect of diagnosis for the amygdala and caudate nucleus and an effect of RDoC domains and constructs for the amygdala, hippocampus, putamen and nucleus accumbens. In contrast, whole‐brain studies did not identify any significant effect of diagnosis or RDoC domain or construct. These results resonate with prior reports of common brain structural and genetic underpinnings across these disorders and caution against attributing undue specificity to brain functional changes when forming explanatory models of psychiatric disorders.

MacKenzie, I. Z. and Hillier, K. (Nuffield Dept. of Obstetrics and Gynaecology, John Radcliffe Hospital, Headington, Oxford, England). Delayed morbidity following prostaglandin‐induced abortion.Int J Gynaecol Obstet 13: 209–214, 1975.Delayed morbidity in 307 patients who had a prostaglandin‐induced abortion 18 months or more previously, has been assessed. Two hundred and sixty‐six replies to questionnaires sent to patients and a further 41 from their general practitioners were analysed to assess reproductive performance and general health subsequent to abortion. Eleven patients had depressive illness including one who attempted suicide shortly after abortion, but no other significant interim illnesses were reported. Menstrual symptoms were infrequent. Fifty‐three pregnancies in 46 of the 307 patients have subsequently occurred, eight resulting in spontaneous abortion, 13 in a further therapeutic abortion and one ectopic pregnancy. In the term pregnancies morbidity was low. The usage of adequate contraception at the time of follow‐up was found to be 80.5% compared with only 33.8% before abortion.

(Dept. of Obstetrics & Gynecology, Nassau County Medical Center, East Meadow, New York, and Health Sciences Center, State University of New York at Stony Brook, USA). Modified radical hysterectomy in treatment of in situ and microinvasive squamous cell carcinoma of the cervix.Int J Gynaecol Obstet 13: 215–218, 1975.This review of the records of 100 patients evaluates the management of in situ and microinvasive carcinoma of the cervix by modified radical hysterectomy in a county hospital from 1970 through 1973. There was no greater incidence of morbidity in 50 patients with early cervical neoplasia who were treated by modified radical hysterectomy than of those 50 patients with benign disease who were treated by simple abdominal hysterectomy. Safety of this procedure has also been documented by other authors. However, whether we are achieving a superior result in treatment of early cervical neoplasia by performing modified radical hysterectomy versus simple hysterectomy remains unanswered at present.
The Clinical Significance of Deviations in Fetal Growth

R. W. Abdul‐Karim, Department of Obstetrics and Gynecology, State University of New York, Upstate Medical Center, Syracuse, N.Y., USA). The clinical significance of deviations in fetal growth.Int J Gynaecol Obstet 13: 257–267, 1975The most commonly employed standard for fetal growth is that of its weight. Such standards have certain drawbacks in that they are based on the weights of preterm liveborn (hence by definition the product of an abnormal pregnancy and not necessarily reflecting the weight of a fetus remaining in utero) and quite frequently are not available for the specific population of a given neonate. The factors that influence fetal weight include paternal size, particularly maternal weight, altitude, fetal sex, multiple pregnancy and race. The construction of intrauterine growth curves must take these into consideration. The importance of considering fetal weight in relation to its gestational age is now evident. Deviations from normal fetal growth are defined rather arbitrarily. The most commonly used limits are those below or above 2 S.D. from the mean or the 10th and 90th percentiles. Such statistical group‐partal, intrapartal and postpartal prognosis varies as to factors accounting for their growth deviation. This in part explains the varied results reported on the follow‐up of these newborns. Fetuses whose birth weight falls below 2 S.D. or the 10th percentile are termed growth retarded. As a group such fetuses have a higher perinatal mortality and morbidity, and their postnatal growth is compromised. However, such newborns do not represent a homogeneous group and their ante‐partal, intrapartal, and postpartal prognosis varies as to whether the infant was the product of a pregnancy complicated by maternal (e.g. toxemias, diabetes) or fetal (e.g. infection, chromosomal abnormalities) disease or was the result of an otherwise uncomplicated pregnancy. In any case the special predilection of growth retarded fetuses to antepartum, intrapartum and neonatal problems warrants intensive assessments during these periods in its development. The growth accelerated (or large for dates) fetus has received less extensive investigation than its counterpart. Such fetuses are often associated with tall heavy mothers or those with certain metabolic diseases (e.g. diabetes, hyperthyroidism). Because of their size they can present obstetrical problems and their postnatal development may be jeopardized. However, there is suggestive evidence that some of the uninjured newborns may have an enhanced postnatal development not only in stature, but mentally as well. It is hoped that the currently available experimental model of growth accelerated fetuses may lead to a better understanding of this aspect of fetal development.

Quiñones, R., Edelman, D. A., Alvarado, A., Ley, E. and Goldsmith, A. (Hospital de Gíneco‐Obstetricia, National Medical Center, Mexican Institute for Social Security, México City, México, and International Fertility Research Program, Research Triangle Park, North Carolina, USA). Female sterilization using the tubal ring.Int J Gynaecol Obstet 14: 489–493, 1976.The surgical and early postoperative complications were evaluated in a study of 221 laparoscopies and 29 minilaparotomies in which tubal occlusions were performed with the application of tubal rings. For either procedure, complications were infrequent. None of the procedures had to be completed by another technique of tubal occlusion, and none of the patients required an extended hospitalization for the treatment of a complication. Among the 79 patients who have been followed up for more than 6 months, no pregnancies have been reported. The tubal ring technique appears to be safe and effective when used with either laparoscopy or minilaparotomy.
Toward Stationary Populations and Beyond
Authors: Kessel Elton 
Published: January 2017

ABSTRACTThe world's rate of population growth is declining. Most industrialized societies have achieved or are moving rapidly toward stationary populations, but while birth rates are also declining in many developing countries, continued growth must be expected because of the large proportions of young people in these populations. New evidence of exceptions to the classical demographic transition theory indicate that declining fertility is compatible with high mortality or low socioeconomic development if acceptable means of fertility control are readily available. “Fertility silhouettes” showing differing age‐specific fertility rates indicate that present family planning programs have had a demographic impact. A review of the economic and ecologic consequences of rapid population growth justifies the conclusion that considerable effort will be required to again bring the world's population into balance with these systems. The author outlines priorities for this effort, with emphasis on the need to devise acceptable means of fertility control that will not tax the frail health care infrastructures of developing countries.
Total Serum Cholesterol, Triglycerides and Phospholipids During the Normal Menstrual Cycle
Authors: Punnonen Reijo 
Published: January 2017

ABSTRACTTen healthy women (mean age, 29 years) with regular menstrual cycles of 26 to 29 days were tested for levels of total serum cholesterol, triglycerides, phospholipids, and estradiol three times during one menstrual cycle—during menstruation, at ovulation, and in the luteal phase. All studies were performed simultaneously. Lipid variations during the menstrual cycle were minimal. Total serum cholesterol, triglycerides, and phospholipids did not correlate with changes in the serum estradiol levels.
The Role of Methylergonovine Maleate in Augmenting Extraamniotic Saline for Midtrimester Abortion

Published: January 2017

ABSTRACTThis study was conducted in Bombay, India, to evaluate the role of oral methylergonovine maleate (Methergine®, Sandoz Pharmaceuticals, East Hanover, N. J., USA) in augmenting the effect of intermittent extraamniotic instillation of 20% saline for midtrimester abortion in 200 patients. Methylergonovine maleate (MEM) administration was randomly allocated to half the study subjects. All the study procedures were performed by a single operator, and to minimize evaluator bias, another physician evaluated all the study patients after abortion. This study showed that a statistically significant higher percentage of patients in the MEM treated group aborted within 24 hours. At 36 and 48 hours, the differences were not statistically significant, although the cumulative abortion rates were higher for subjects who received the drug than for those who did not. The incidence of incomplete abortions was lower for those treated with MEM than for those not treated with the drug, but the difference was not statistically significant. The rates of complications and side effects were similar for both study groups.
Galactorrhea and the Defective Luteal Phase of the Menstrual Cycle
Authors: Mahgoub S. El 
Published: January 2017

ABSTRACTTwelve patients with primary infertility due to a defective luteal phase associated with hyperprolactinemia and galactorrhea are reported. All were treated with 2‐bromoergocryptine. During the first cycle of therapy, the serum prolactin level decreased in all cases, and galactorrhea disappeared during the second cycle of therapy. Seven women responded to 2‐bromoergocryptine, as was reflected in their endometrial biopsies. The remaining five were given clomiphene citrate on the second and sixth days of the next 2‐bromoergocryptine cycle. Three of these patients responded favorably to this combined therapy. Six pregnancies were reported during therapy. The results of follow‐up after labor or abortion suggested that these cases represent a latent stage of the amenorrhea‐galactorrhea syndrome.
Pregnancy and Labor in Tanzanian Primigravidae Aged 15 Years and Under
Authors: Arkutu A. A. 
Published: January 2017

ABSTRACTThe outcome of pregnancy and labor in 259 Tanzanian primigravidae 15 years and under is compared with that of 377 primigravidae between the ages of 21 and 25. The risk of antenatal complications, such as anemia, and premature labor and low birth weight babies was much higher in the younger age group. There was no difference in the incidence of preeclampsia or complications during labor between the two groups. The younger women had a lower perinatal mortality rate than the controls.
Uterine and Peripheral Hematologic Profiles in Molar Pregnancy
Authors: Lopez‐Llera Mario , Ramos José Niz , de la Luz Espinosa María 
Published: January 2017

ABSTRACTThe potential differences in hematologic profiles of blood samples drawn simultaneously from the right utero‐ovarian vein and from the upper extremity were investigated in four patients with uncomplicated molar pregnancy in stable obstetric conditions. The patients had undergone no previous chemotherapy and were scheduled for total abdominal hysterectomies. The dominant abnormalities in uterine venous blood were prolongation of thrombin time; shortening of activated partial thromboplastin time; positive protamine sulfate test; and increase in coagulation factors II and VII, with a tendency to low values in factor V. Peripheral samples gave almost parallel results in all altered and normal tests, except in one case with very striking differences in factors II, V, VII and X. Several local and systemic influences are discussed. It is concluded that molar pregnancy seems to have important systemic mechanisms affecting the stability of the blood coagulation homeostasis, which act in addition to those at a local level.
Recessive Congenital Myotonia and Pregnancy
Authors: Schwartz Irwin L. , Dingfelder James R. , O'Tuama Lorcan , Swift Michael 
Published: January 2017

ABSTRACTThere is a group of genetic disorders of muscle associated with myotonia. Congenital myotonia, usually a benign disorder and myotonic dystrophy, potentially a serious disorder, belong to this group. Uterine recordings during labor in patients with congenital myotonia have not been previously reported. These records have been abnormal in patients with myotonic dystrophy which has been associated with serious obstetric complications. A case of congenital myotonia in pregnancy is reported. The record of uterine contractions was normal. Although the patient delivered a stillborn male, the etiology of the intrauterine fetal demise is obscure.

Induction of Ovulation with Epimestrol and Luteinizing Hormone‐Releasing Hormone (LH‐RH)
Authors: Maia H. , Barbosa I. , Maia H. , Nascimento A. J. , de Souza M. Bonfim 
Published: January 2017

ABSTRACTLuteinizing hormone‐releasing hormone (LH‐RH) was used to induce LH surge and ovulation in 20 patients in whom follicular maturation was provoked by epimestrol, used in a dose of 5 mg/day from the fifth to 14th day of the cycle. Patients with elevated prolaction levels and galactorrhea were not included in the study. Complete follicular maturation, as inferred by estradiol levels above 200 pg/ml, were observed in 13 of 20 patients following epimestrol treatment. LH‐RH induced ovulation in 90% of these patients following a three‐day course of treatment. Normal corpus luteum function with progesterone levels above 8 ng/ml was observed in most cases. Five pregnancies occurred in the first two cycles of treatment. In patients with low estradiol levels, following epimestrol priming, the administration of LH‐RH did not result in ovulation.
