SAR Image Ship Object Generation and Classification With Improved Residual Conditional Generative Adversarial Network

Image generation by the conditional generative adversarial network (CGAN) can provide rich samples for supervised classification tasks. However, the unstable gradient updating problem makes it difficult to be used for image generation, especially for the high-resolution SAR image. In this letter, an improved residual condition generation network is proposed to enhance the quality of generated images and classification accuracy for hard negative examples. First, a residual convolutional-based block is built to clear the detail texture of different types of targets. Then, the gradient penalty and Wasserstein loss are used as discriminators to improve the similarity between real samples and the intra diversity of a generated images. We test the proposed method on generation and classification of three kinds of commercial ships using C-band 3-m Gaofen-3 (GF-3) SAR images. Experimental results show that our method can generate high-quality ship samples and achieve good classification accuracy.
The correlation between figural and conceptual properties of angle and cube in pre-service teachers geometric reasoning

Drawing upon Fischbein's theory of figural concepts, the starting point of the paper is the use and value of the history of geometry in mathematics education - first point that we make historical reference are theorems of Eudemus of Rhodes and Thales of Miletus and the second one is elaboration of these theorems in work of Serbian mathematicians Mihailo Petrovic Alas. Fischbein's theory is mainly based on a hypothesis that geometry deals with mental entities, the so-called geometric figures, which simultaneously possess conceptual and figural properties. Fischbein called the geometric figures figural concepts because of their nature. We have analyzed the internal tensions of the concepts of angle and cube, which may appear in figural concepts because of their double nature, developmental aspects and didactical implications. The goal of the research was to examine the pre-service primary school teachers' geometric reasoning regarding the correlation between figural (pictoral) and conceptual properties of geometric objects (angle and cube) in order to obtain a framework for creating didactic situations that reduce the gap between figure and concept. The results of this study show that the figural (pictoral) structure of an angle (and cube) dominates in the geometric reasoning of the pre-service primary school teachers over its formal conceptual constraints. There were some differences in situations when an image is helpful in solving tasks involving the concepts of the net of the cube and the cube itself.
Genital tract infection and associated factors affect the reproductive outcome in fertile females and females undergoing in vitro fertilization

Assisted reproductive techniques including in vitro fertilization (IVF) are being used increasingly worldwide and screening for genital tract infections (GTIs) is recommended prior to treatment as their presence may affect the success rate of IVF. The current study aimed to assess the possible associations between GTI-associated factors and reproductive outcome in a group of reproductive age fertile females and infertile females receiving IVF. A total of 111 infertile women enrolled in an IVF programme (Group A) and 104 fertile women (mothers of at least one child; Group B) underwent microbiological screening of vaginal and cervical samples. All samples were cultured using different protocols for aerobic pathogens, bacterial vaginosis (BV), Ureaplasma urealyticum, Mycoplasma hominis, Chlamydia trachomatis and human papilloma virus (HPV). Although each group were comparable in age, more infertile women were >30 years (P=0.0064), had a higher education level (P=0.0001) and were smokers (P=0.007). Only BV (P=0.0013) was more prevalent in Group A. Of the 111 infertile females who were scheduled for IVF, 32 females had a successful pregnancy (Group C) and 79 females exhibited IVF failure (Group D). Tubal factor (P=0.012), estradiol-2 (E2) levels <2,500 pg/ml (P=0.0009) and Mycoplasma infection (P=0.003) were identified to be the strongest predictors of IVF failure. The current study determined certain GTI-associated factors that may contribute to infertility in Greek females of reproductive age as well as other risk factors associated with failure in patients undergoing IVF. Further studies are required to confirm this conclusion.
A Comparative Study of the Use of Cassava Species and Alum in Waste Water Treatment

This research was conducted to study the performance of two varieties of cassava as coagulants in waste water treatment and compare them with alum. Heavy metals composition of the two varieties of cassava used were also studied. The results showed that, the acid treated portion of specie A (Manihot palmate) recorded 51.8 % turbidity reduction efficiency and 70 % reduction in alkalinity; while for the untreated portion of specie A recorded 60 % reduction in alkalinity. The acid treated portion of specie B (Manihot aipi) recorded a 58.3 % reduction in turbidity and 80 % reduction in alkalinity; while the alum reduced the turbidity by 43.7% at the dosage of 50ml. The untreated portion of specie B, showed 80 % reduction in TSS and a 70 % reduction in alkalinity. The heavy metals contents of the two species of cassava were obtained as: Cu (0.077 µg/g), Cd (0.000 µg/g), and Zn (0.231 µg/g), Ni (0.168 µg/g), Mn (8.516 µg/g) and Pb (0.144 µg/g) for specie A and Cu (0.086 µg/g), Cd (0.000 µg/g), Zn (0.258 µg/g), Mn (9.624 µg/g) and Pb (0.047 µg/g) for specie B; while the heavy metals contents of the wastewater were: Cu (0.036 mg/l), Cd (0.056 mg/l), Zn (0.269 mg/l), Ni (0.000 mg/l), Mn (0.505 mg/l) and Pb (0.137 mg/l). It was concluded that the two cassava species were more effective than alum as coagulants in wastewater treatment. http://dx.doi. org/10.4314/njt.v33i2. 5

Reformulation of the Roy–Shafai Generalization of the Ludwig-3 Co-/Cross-Polarization Definition

The Roy–Shafai generalization of the Ludwig-3 polarization pattern definition is well-suited to the representation of the far electromagnetic field of a flanged aperture, either a perfect electric conductor (PEC)-flanged aperture with an impressed electric field as was shown by Roy and Shafai or a perfect magnetic conductor (PMC)-flanged aperture with an impressed magnetic field which can be similarly derived. We show that the Roy–Shafai generalization of the Ludwig-3 polarization definition is in fact equivalent to the transformed Ludwig-2 definition. The Ludwig-3 polarization is that of a Huygens source, while the Ludwig-2 polarization definition corresponds to either an electric or, with transformation, a magnetic dipole. That the Roy-Shafai polarization definition is equivalent to a transformed Ludwig-2 definition is reasonable as the rectangular PEC-flanged aperture with an impressed electric field behaves as a magnetic dipole in the low frequency limit and, subject to some restrictions, maintains the same polarization pattern for all frequency assuming the aperture field remains uniform. Likewise, the rectangular PMC-flanged aperture with an impressed magnetic field behaves like an electric dipole in the low-frequency limit and maintains the same polarization pattern for all frequency again, assuming that the aperture field remains uniform and, thus, exhibits a Ludwig-2 polarization pattern.
Data-Driven Trajectory Quality Improvement for Promoting Intelligent Vessel Traffic Services in 6G-Enabled Maritime IoT Systems

Future generation communication systems, such as 5G and 6G wireless systems, exploit the combined satellite-terrestrial communication infrastructures to extend network coverage and data throughput for data-driven applications. These ground-breaking techniques have promoted the rapid development of Internet of Things (IoT) in maritime industries. In maritime IoT applications, intelligent vessel traffic services can be guaranteed by collecting and analyzing high volume of spatial data flows from automatic identification system (AIS). This AIS system includes a highly integrated automatic equipment, including functionalities of core communication, tracking, and sensing. The increased utilization of shipboard AIS devices allows the collection of massive trajectory data. However, the received raw AIS data often suffers from undesirable outliers (i.e., poorly tracked timestamped points for vessel trajectories) during signal acquisition and analog-to-digital conversion. The degraded AIS data will bring negative effects on vessel traffic services (e.g., maritime traffic monitoring, intelligent maritime navigation, vessel collision avoidance, etc.) in maritime IoT scenarios. To improve the quality of vessel trajectory records from AIS networks, we propose to develop a two-phase data-driven machine learning framework for vessel trajectory reconstruction. In particular, a density-based clustering method is introduced in the first phase to automatically recognize the undesirable outliers. The second phase proposes a bidirectional long short-term memory (BLSTM)-based supervised learning technique to restore the timestamped points degraded by random outliers in vessel trajectories. Comprehensive experiments on simulated and realistic data sets have verified the dominance of our two-phase vessel reconstruction framework compared to other competing methods. It thus has the capacity of promoting intelligent vessel traffic services in 6G-enabled maritime IoT systems.

Evaluation of a novel technique for measuring reaeration in rivers

Depletion of dissolved oxygen (DO) is one of the most common forms of river pollution. In extreme cases, it can result in fish kills, foul odours and can prohibit the use of water for drinking and other purposes. Regulatory authorities therefore place great importance on their ability to predict depletion of DO in waters which receive wastewater discharges and agricultural runoff.To date, predictive water quality models have relied almost totally on empirical methods to estimate the overall controlling factor for mass transfer of oxygen from the atmosphere into water bodies, the reaeration coefficient (K2). However, this coefficient varies from one river to another and changes with changing hydraulic conditions within a reach. Poor estimates have often led to inaccurate predictions of water quality.This paper describes the development of a novel method for the direct measurement of the reaeration coefficient in any river. This direct approach utilises two tracers - one volatile, one conservative - but, unlike previous tracer studies reported by other authors, it does not rely on the use of radioactive materials to achieve sensitive and precise measurement. Instead both tracers used are generally deemed 'environmentally friendly': the inert gas, Krypton, and the recognised fluorescent water tracer, Rhodamine WT, are used to quantify the reaeration coefficient. The adopted method is based on highly sensitive measurements of these substances using Gas Chromatography Mass Spectrometry (GC-MS) and fluorimetry techniques respectively.The outcome of field tests in a major river in Northern Ireland is reported. Issues affecting the precision of the method are addressed and the practicalities of applying it are discussed.
Comparison of the C-MAC D-Blade videolaryngoscope and direct laryngoscope in pediatric patients: Randomized controlled trial.

BACKGROUND Endotracheal intubation is a key skill for clinicians and may be challenging in some patients due to various reasons. Nowadays, various kinds of videolaryngoscopes are available and usually used as a rescue device when direct laryngoscopy failed. Pediatric airway has some differences when compared with adults and may be challenging. This study aims to compare and evaluate C Mac D-Blade and commonly used Macintosh laryngoscope in pediatric patients. METHODS In this study, 56 pediatric patients, 5-10 years old (10-40 kgs) who had undergone elective surgery and need endotracheal intubation were included after obtaining ethical board approval and informed consent from parents. The patients were randomized into two equal groups for laryngoscopy and intubation by either with Macintosh laryngoscope or C Mac D-Blade videolaryngoscope. Glottic view, number of attempts, intubation time, any complications and hemodynamic variables were recorded. A value of p<0.05 was considered significant. RESULTS In pediatric patients with unanticipated difficult airway, the mean intubation time was significantly shorter with C Mac D-Blade (21±9 and 41±7 seconds, respectively (p<0.001). The results of the two groups were similar concerning the remaining parameters. CONCLUSION C Mac D-Blade videolaryngoscope shortened intubation time about twice when compared to Macintosh blade C Mac D-Blade videolaryngoscope, Videolaryngoscopes may be a good alternative for routine intubation, education and a rescue device for difficult intubation.
Exploring Factors That Influence the Uptake of Maternal Health Care Services by Women in Zimbabwe

The study investigated factors that influence the uptake of maternal healthcare services by women in Zimbabwe, using a logit model. Data from the Zimbabwe Demographic Health Survey (ZDHS, 2015) was used. Deteriorating maternal health indicators motivated the study. The effect of socio-economic and demographic factors on the probability of utilising maternal healthcare services was examined. Descriptive statistics and a logit model were used for data analysis. Results from the logit model show that region of residence, insurance cover, educational level, employment status, maternal age, birth order, place of residence, number of living children, maternal age and household income all influence the utilisation of maternal healthcare services by women in Zimbabwe. Basing on research findings, the study recommends that relevant authorities make more available vocational training centres and education institutions since education was found to influence the uptake of maternal healthcare services. There is need to encourage family planning so as to reduce the number of children, especially among the apostolic sect, which affects the uptake of maternal healthcare. Compulsory national health insurance schemes could be adopted to mitigate the effect of low income that discourages the use of institutional facilities for delivery. The issue of balanced regional development needs to be pursued through accelerating devolution to ensure equal access to maternal healthcare facilities in all provinces.
Effet des substitutions d'essences forestières sur l'évolution des sols et de leur minéralogie : bilan après 28 ans dans le site expérimental de Breuil (Morvan)

The aim of this work was to measure the effect of different forest species on the same acid soil and its mineralogy. The site was described in detail by studying the parent material and a soil profile. The study was carried out at Breuil Experimental Site in Morvan, France, which was set up in 1976. The species studied were: native forest species in a broad-leaved Coppice with Standards (CwS), oak, beech, Norway spruce, Douglas fir, Nordmann fir and Corsican Laricio pine. Several methods were used: i) the physico-chemical properties of the fine earth; ii) the mineralogy of the fine soil fractions; iii) the present functioning of the soil using vermiculite placed in situ in the soil as a test-mineral, in parallel with a dissolution experiment on the same mineral in a controlled environment; and iv) the physico-chemical and mineralogical properties of the rhizospheric soil under oak and spruce. The results indicated that the granite was acid and very poor in basic cations. In comparison with the broad-leaved trees, the conifers caused additional desaturation and acidification of the exchange complex of this soil. Examination of the clay fraction showed that Douglas fir and pine caused a much greater dissolution of certain clay mineral phases than the spruce and broad-leaved trees. Mineral weathering was also greater in the rhizospheric soil, than in the total soil, especially below spruce which was related to the ammoniacal form of nitrogen nutrition. Changes observed in the solid soil phase were satisfactorily explained by the integration of the properties of the bio-geo-chemical cycle of each species. This study provides interesting information relevant to forest managers.
Meat quality traits of Vietnamese indigenous Noi chicken at 91 days old

Indigenous chicken breeds have showed slower growth rate and yield lower meat production, compared to commercial broilers. However, their meat quality is valued by modern consumers. The present study aimed at analyzing the quality traits of breast meat samples of Noi broilers, one of the famous indigenous chicken breeds in Vietnam. A total of 355 breast fillet samples were collected to evaluate quality meat traits such as pH, surface color, drip loss, and cooking loss at different time points of 3, 24, and 48 hours after slaughtering as well as to analyze chemical compositions such as dry matter, crude protein and ether extract. As result, sex and cold-storage time significant affect some of quality traits of breast meat, whereas their interaction did not associate among the observed properties. After 3 hour-storage, the pH value was determined at 5.63, then decrease to 5.56 and 5.55 after 24 and 48 hours, respectively. The color values (L*, a*, and b*) were in the normal range reported from previous studies. Meat samples of two sexes did not vary in the cooking loss and drip loss values, whereas it was significantly different due to cold-storage time. The ether extract content of the meat was found negatively correlated with the cooking loss. The higher dry matter content of breast meat resulted in the lower drip loss value after 3h coldstorage (r=-0.12, P<0.05). There is a negative relationship between L* and a*. The variation demonstrated in this study can be used in breeding schemes in order to improve meat quality of Noi chicken lines.
Effect of hatching time on yolk sac percentage and broiler live performance.

This study investigated the effects of broiler chick hatching time on the percentage of the yolk sac and subsequent broiler live performance. Broiler hatching eggs were obtained from a commercial flock at 55 wk of age and were stored for 2 d at 18°C and 75% relative humidity (RH) prior to incubation. Chicks were identified as hatching Early (471-477 h), Middle (480-486 h), and Late (494-510 h). All chicks were removed from the trays at 510 h of incubation. Body weight (BW) and yolk weight (YW) were determined at emergence from the shell (initial hatch time) and at placement on feed. Chicks were permanently identified by hatch time with neck tags, feather sexed, weighed, and introduced to feed and water in litter floor pens. Broiler BW and feed consumption (FC) were then determined 7, 21, and 35 d of age. Mortality was recorded daily. Although the percentage of the yolk was similar at hatch time, it was less in Early compared to Middle and Late chicks at placement (p≤0.05). Broiler chick BW was greater at placement in Late chicks compared to Early and Middle chicks (p≤0.05) but this advantage disappeared by 7 d because Late chicks consumed less feed to 7 d (p≤0.05). Early hatched broilers exhibited greater BW than Late with Middle broilers intermediate at 35 d (p≤0.05). There were no significant differences in feed consumption and feed conversion ratio (FCR) at 35 d of age. Additionally, late hatch chicks exhibited greater mortality. Overall, live performance of Late hatching chicks, judged by mortality and BW at 35 d, was reduced compared to Early hatching chicks.
