Incidence, characteristics, pattern and management of ovarian cancer in Abuja, Nigeria

Background: The prevalence of ovarian cancer is thought to be increasing with huge burden of the disease with no comprehensive cancer center that can offer appropriate care in developing countries. However, little is known about the incidence, pattern and outcome of this disease in Abuja, Nigeria. Therefore, the aim of this study was to review the pattern of care offered to patients with ovarian cancer in our center and to evaluate patients’ outcome.Methods: This was a retrospective review of all the patients with histologically confirmed ovarian cancers admitted to the gynecological ward of the hospital over a period of 5 years. Relevant information was extracted from the ward register and patients medical case records. Data were analyzed using statistical package for social science version 23 and results were then presented in tables and chart.Results: Ovarian cancers constituted 19.6% and 5.6% of all gynecological cancers and all gynecological admissions respectively. The mean age at presentation was 50.2±8.5 years and premenopausal 32 (55%) constituting the majority. A large proportion 43 (74.1%) of the patients were parous. The commonest symptoms at presentation were abdominal swelling (86.2%), and abdominal pain (53.4%) with the majority 38 (65.5%) presenting in an advanced stage. The commonest histological type of ovarian cancers was epithelial accounting for 30 (51.7%) of all ovarian cancers. Common treatment modality was surgery and chemotherapy and majority 32 (55.3%) of the patients had cytoreductive surgery with 19 of them having optimum cytoreduction and 33 (57%) benefitted from chemotherapy. Lost to follow- up was significantly high (55%) and mortality rate was 15.5%. Conclusion: Cases of ovarian cancers are on the increase. Women presented at an advanced stage of the disease, which resulted in short survival times. Failure of optimal management was also worsened by poor compliance to treatment with high patients' default rate.
Study of Deformation and Breakup of Submillimeter Droplets’ Spray in a Supersonic Nozzle Flow

The problem of secondary atomization of droplets is crucial for many applications. In high-speed flows, fine atomization usually takes place, and the breakup of small droplets determines the final products of atomization. An experimental study of deformation and breakup of 15–60 µm size droplets in an accelerated flow inside a converging–diverging nozzle is considered in the paper. Particle image velocimetry and shadow photography were employed in the experiments. Results of gas and liquid phase flow measurements and visualization are presented and analyzed, including gas and droplets’ velocity, shape and size distributions of droplets. Weber numbers for droplets’ breakup are reported. For those small droplets at low Weber numbers, the presence of well-known droplets’ breakup morphology is confirmed, and rare “pulling” breakup mode is detected and qualitatively described. For the “pulling” breakup mode, a consideration, explaining its development in smaller droplets through shear stress effect, is provided.

Membrane-Supported Recovery of Homogeneous Organocatalysts: A Review

As catalysis plays a significant role in the development of economical and sustainable chemical processes, increased attention is paid to the recovery and reuse of high-value catalysts. Although homogeneous catalysts are usually more active and selective than the heterogeneous ones, both catalyst recycling and product separation pose a challenge for developing industrially feasible methods. In this respect, membrane-supported recovery of organocatalysts represents a particularly useful tool and a valid option for organocatalytic asymmetric synthesis. However, catalyst leaching/degradation and a subsequent decrease in selectivity/conversion are significant drawbacks. As the effectivity of the membrane separation depends mainly on the size of the catalyst in contrast to the other solutes, molecular weight enlargement of small organocatalysts is usually necessary. In the last few years, several synthetic methodologies have been developed to facilitate their recovery by nanofiltration. With the aim of extending the possibilities for the membrane-supported recovery of organocatalysts further, this contribution presents a review of the existing synthetic approaches for the molecular weight enlargement of organocatalysts.
Sequential spectrum sensing based on multiple antennas with low computational complexity statistic

: This letter presents a multiple antenna based spectrum sensing via a sequential detection technique. A log-likelihood ratio test of a low computational complexity statistic is deﬁned and we develop the sequential detection based spectrum sensing using the test. The presented technique can reduce the computational complexity by overlapping samples for the calculation of each statistic while almost maintaining the accuracy of signal detection. Numerical examples are shown to validate the eﬀectiveness of the presented technique.
Tandem Synthesis of High Yield MoS2 Nanosheets and Enzyme Peroxidase Mimicking Properties

Molybdenum Sulfide nanosheets (MoS2 NSs) have unique properties that allow its use in a wide range of applications. Unfortunately, a lack of green synthesis methods to achieve a high yield remains a challenge after decades. Herein we report a simple, ecofriendly, green and cost-effective approach to synthesize water soluble MoS2 NSs via probe/Tip sonication method. The sequential batch manner pathway allows us to attain a high yield of MoS2 NSs (~100%). The prepared MoS2 NSs were characterized using up-to-date surface science techniques. UV-visible-NIR spectroscopy allowed us to visualize the doublet peaks of pristine MoS2 at 610 and 680 nm concomitant with the inter-band transitions at 394 nm and 460 nm. Using Transmission Electron Microscopy (TEM) and Dynamic Light Scattering (DLS), the crystallites’ sizes were estimated. X-ray diffraction (XRD) and Raman Spectroscopy were performed with respect to the bulk MoS2. The energy difference between the Raman peaks revealed that our NSs are formed of 5–6 layers. Further, we explored enzyme peroxidase mimetic properties of the synthesized MoS2 NSs. Results showed that the present MoS2 NSs offer excellent peroxidase mimicking properties. Most importantly, we observed that the optical properties and characteristics of MoS2 NSs synthesized by the current green method are similar to those of MoS2 NSs synthesized using conventional harsh methods reported in the literature. So that we strongly assume that the present method is a green alternative for the existing low yield and harsh experimental procedures to achieve water soluble MoS2 NSs in high yield. The synthesized soluble NSs are promising catalysts for the detection of toxic chemicals in the environment and/or for following enzymatic chromogenic reactions.
A new species of tapaculo (Rhinocryptidae: Scytalopus) from the Western Andes of Colombia

ABSTRACT We describe Scytalopus alvarezlopezi from the Western Andes of Colombia. The new species forms part of a distinctive clade of Scytalopus tapaculos (Rhinocryptidae) that also includes S. robbinsi from Ecuador and S. stilesi and S. rodriguezi, which occur on the Central and Eastern Andes of Colombia. S. alvarezlopezi is easily diagnosable from its near relatives by its song and mitochondrial DNA; differences in plumage exist but are more subtle. The species inhabits dense understory vegetation on the floors and lower slopes of ravines in cloud forest at elevations of 1,300 to 2,100 m. On the Pacific slope, its altitudinal distribution is sandwiched between those of S. chocoensis (below) and S. vicinior (above); the latter in turn is replaced higher up by S. spillmanni and S. latrans, but S. alvarezlopezi also occurs at ∼2,000–2,100 m on eastern slopes just below the low ridgeline. All of the latter species are distinguished by vocal and plumage characters. Marked sexual differences in plumage exist in stilesi, but females have yet to be collected for alvarezlopezi and rodriguezi. We consider that S. alvarezlopezi is not threatened at present, but could be potentially vulnerable due to its restricted distribution; it is endemic to Colombia.
Paleoallium billgenseli gen. et sp. nov.: Fossil Monocot Remains from the Latest Early Eocene Republic Flora, Northeastern Washington State, USA

Premise of research. Fossil inflorescences (scapes) producing both pedicellate flowers and sessile bulbils, both covered partially by a persistent spathe, are described from the latest early Eocene Republic flora of north-central Washington. They are associated with an individual specimen of a single bulb with attached roots, and two small flower buds that appear to represent the same plant. The morphology of these fossils closely resembles that of certain bulb-forming monocots, such as some species of the onion genus Allium and other members of Amaryllidaceae. Methodology. Compression-impression fossils preserved in a lacustrine shale were uncovered from the rock matrix to reveal morphological details and were photographed with LM. Specimens were compared morphologically with extant material of related plants, and resulting images were processed minimally with Adobe Photoshop. Pivotal results. Specimens demonstrate an organography that is quite similar to that of modern onions and related forms. To our knowledge, this is the first description of plants showing a combination of bulbils and florets (representing asexual and sexual reproduction) among Paleogene plants. It also represents one of few reports among the fossil record of monocot plants similar to members of Amaryllidaceae. Conclusions. Scapes bearing flowers and bulbils within a spathe similar to those of some modern Amaryllidaceae, associated flower buds, and a root-producing bulb indicate the presence of a distinctive monocot plant in the Republic flora of the latest early Eocene Okanogan Highlands, northeastern Washington. Along with other Republic plants with distinctive morphological features indicative of temperate floras (leaf dimorphism, possible hybridization), these fossils suggest that bulbil- and flower-bearing monocots with a combined asexual and sexual reproductive strategy were already well established among plants of Paleogene.
Read Range Optimization of Low Frequency RFID System in Hostile Environmental Conditions by Using RSM Approach

RFID system plays a major role in asset tracking but its performance may get challenged when it has to work in extreme atmospheric conditions. RFID system can play an important role in military or defense purpose to track the land mines, military containers etc. Keeping these things in mind, this research work was carried out for the military areas which are situated in arid and semiarid regions. In this research work, experimental investigation, statistical analysis and optimization of the low frequency RFID system read range has been carried out with respect to four major input parameters i.e. varying sandy soil grain sizes (0.45 mm, 0.78 mm, 1.18 mm, 1.6 mm and 2 mm) which is present in between RFID reader and tag, temperature (15 °C to 50 °C), humidity (35 %RH to 70 %RH) and sandy soil layer thickness (0 mm to 90 mm). Here the optimization is being done by using response surface methodology (RSM). From the investigations and optimization it was found that maximum value of read range which the LF RFID system can attain is 118.14 mm for the optimum combination of input variables i.e. temperature, soil layer thickness, relative humidity and soil grain size were found to be 25.606 °C, 0 mm, 35 % and 2 mm respectively.
Low-Complexity Run-time Management of Concurrent Workloads for Energy-Efficient Multi-Core Systems

Contemporary embedded systems may execute multiple applications, potentially concurrently on heterogeneous platforms, with different system workloads (CPU- or memory-intensive or both) leading to different power signatures. This makes finding the most energy-efficient system configuration for each type of workload scenario extremely challenging. This paper proposes a novel run-time optimization approach aiming for maximum power normalized performance under such circumstances. Based on experimenting with PARSEC applications on an Odroid XU-3 and Intel Core i7 platforms, we model power normalized performance (in terms of instruction per second (IPS)/Watt) through multivariate linear regression (MLR). We derive run-time control methods to exploit the models in different ways, trading off optimization results with control overheads. We demonstrate low-cost and low-complexity run-time algorithms that continuously adapt system configuration to improve the IPS/Watt by up to 139% compared to existing approaches.
Formação de raízes em estacas de duas espécies de Calliandra (Leguminosae - Mimosoideae)

(Root formation in cuttings of two species of Calliandra (Leguminosae Mimosoideae)) Calliandra brevipes and Calliandra tweedii, known as ‘caliandra’ or ‘esponjinha’, are native Brazilian ornamental species. This experiment aimed to evaluate the effect of the application of different concentrations of Indolbutiric acid (IBA) in root formation of both species by observing anatomical structure. Both species presented an increase in root formation percentage and number of new roots when treated with IBA. All Calliandra brevipes treatments achieved higher root formation percentages than Calliandra tweedii. The best results of C. brevipes were 2000 mg.L IBA (56,67%). C. brevipes had 90% of rooting without IBA application. Roots originated directly for both species, either from the inner or outer phloem region. Probably the limiting factors for C. tweedii root formation were linked to its anatomy and physiology, such as the absence of starch granules in the medular region.
Modification level and test of scientific argumentation skill: Development and validity

This study focuses on developing the new level of scientific argumentation skills and new items that are feasible and valid for use. The level was determined based on the ability in making claims, the data or facts, warrant, backing, and rebuttal. There were seven experts of participants and 195 high school students involved in this study. The analysis was conducted based on content validity, INFIT MNSQ, INFIT t and item difficulty level. The developed test proved to be valid and feasible to be used to measure the scientific argumentation skills of students. The reliability values of the estimation of the items of reliability and case estimation reliability being collected items, namely 0.79 and 0.70 (Medium). The modification of the level of scientific argumentation skills indicate the ability of students is still deficient. At level 1 (claims) there were only 38.9% students, level 2 (data) were 21.6% students, level 3 (warrants) 16.6% students, level 4 (backing) 16.2% while level 5 (rebuttal) is the most difficult, for students users only by 4.2%. Thus, most students (61.2%) are still unable to make scientific arguments even at level 1. Based on the findings, the test can measure and show with a separate level of students' scientific argumentation skill.

MtDNA differentiation and taxonomy of Central Asian racerunners of Eremias multiocellata - E. przewalskii species complex (Squamata, Lacertidae)

We provide an integrative analysis of the diversity of the E. multiocellata—E. przewalskii species complex in Central and Middle Asia using morphological and molecular (COI DNA-barcoding) data. We report preliminary data on mtDNA variation within this group and clarify the taxonomic status and distribution of the members of the species complex. We also provide a description of a new Eremias species from Eastern Kazakhstan and western Mongolia, where it occurs in sympatry with E. multiocellata sensu stricto, from which it can be clearly differentiated using both morphological and molecular characters. The new species, described as Eremias dzungarica sp. nov., is assigned to the subgenus Pareremias on the basis of the following features: subocular not reaching mouth edge; one frontonasal; two supraoculars; the row of small granular scales between supraoculars and frontal with frontoparietals absent; distance between the femoral pore rows being wide; femoral pore rows not reaching knee-joint; coloration pattern with light colored ocelli with black edging. The new species can be distinguished from its congeners on the basis of the following morphological attributes: a medium-sized lacertid lizard, maximum snout-vent length (SVL) = 64.5 mm, tail being ca. 1.5 times longer than body length (SVL), hindlimbs relatively long (hindlimb length to SVL ratio 0.46); subocular scale not reaching mouth edge, in touch with 6–8 supralabials; males with bright coloration consisting of 2–3 dorsolateral rows of light-colored ocelli with thick black edging; the ventral row of ocelli in life is greenish to bluish; dorsal pattern consisting of black irregular blotches along the middorsal line. We also report on the high genetic and morphological diversity of E. multiocellata in Mongolia and China, synonymize E. m. bannikowi with the nominative form E. m. multiocellata , discuss variation within E. przewalskii , synonymize E. p. tuvensis with the nominative form E. przewalskii , provide new data on E. cf. reticulata and E. m . tsaganbogdensis , confirm validity and clarify distribution ranges of E. stummeri , E. szczerbaki and E. yarkandensis and discuss further progress on taxonomic studies of the E. multiocellata—E. przewalskii species complex.
Tenacious wall states in thermal convection in rapidly rotating containers

Convection in a container, heated from below, cooled from above and rapidly rotated around a vertical axis, starts from its sidewall. When the imposed vertical temperature gradient is not sufficiently large for bulk modes to set in, thermal convection can start in the form of wall modes, which are observed near the sidewall as pairs of hot ascending and cold descending plumes that drift along the wall. With increasing temperature gradient, different wall and bulk modes occur and interact, leading finally to turbulence. A recent numerical study by Favier & Knobloch (J. Fluid Mech., 895, 2020, R1) reveals an extreme robustness of the wall states. They persist above the onset of bulk modes and turbulence, thereby relating them to the recently discovered boundary zonal flows in highly turbulent rotating thermal convection. More exciting is that the wall modes can be thought of as topologically protected states, as they are robust with respect to the sidewall shape. They stubbornly drift along the wall, following its contour, independent of geometric obstacles.
BODY SHAMING, EMOTIONAL EXPRESSIVITY, AND LIFE ORIENTATION AMONG YOUNG ADULTS

Mockery of someone’s body type leads to degradation in mental well being and lack of confidence. To understand the consequences of body shaming, we must evaluate the three aspectsbody image, emotional expression, and life orientation. The aim of this study is to understand the relationship between body shaming and body image, life orientation and emotional expression. The interplay between these aspects determines one’s personality and how we see the world around us. This study incorporated 150 participants including 75 males and 75 females. Snowball sampling was used to collect responses from the participants. Three scales were used to form a survey questionnaire that assessed respective aspects. The results revealed an insignificant relationship between the body image of males and females, and a significant relationship between body image and emotional expressivity which was found to be positive. However, there exists a significant and negative relationship between body image and optimism. Hence, this proves our hypothesis that people with positive body image can express their emotions well, but disproves the fact that positive body image can lead to a good level of optimism.
The Difference of Cadre Knowledge Before and After Handwashing Tele-Education in COVID-19 Outbreak at Burangrang Village, Bandung

Background: Health prevention and promotion are both important in making better public health. In order to actualize both aspects, Posyandu cadre play major role. Cadre have bigger chance and impact to educate the people who are living around them. However, doing a direct education has become more difficult since physical contacts were minimalized during this COVID-19 outbreak. Therefore, an effective tele-education is needed as an effort to prevent COVID-19 transmission. The study aims to evaluate the effect of tele-education through Youtube and Whatsapp to enhance people's understanding on COVID-19 transmission prevention Method: The study was a cross-sectional study with observational descriptive-analytical methods and quantitatively approach. Subject of the study was Posyandu cadre in Burangrang Village, Lengkong District, Bandung with the subject total was 19. Results: After given a tele-education, there was an increase in total score means between pretest and posttest with p=0.000 (p<0.001). Moreover, there were increases in both social media’s impression and engagement on educational video which was uploaded on Youtube. Discussion: In doing tele education to Posyandu cadre, video as a media to deliver the content was more preferred. Sharing the knowledge through video along with evaluating participants' understanding of the given topics could enhance cadre knowledge about handwashing as a prevention in the middle of COVID-19 outbreak. Conclusion: Tele education using video could enhance cadre’s understanding about handwashing. The media that has been used was able to deliver the content based on impression and engagement evaluations.
