Food Exploitation Patterns in an Assembly of Estuarine Herons

Abstract I examined the food exploitation patterns of three day herons, Great Egret (Ardea alba), Snowy Egret (Egretta thula), Tricolored Heron (E. tricolor) and a nocturnal species, the Black-crowned Night-Heron (Nycticorax nycticorax) that nested together in an estuarine colony. Types and sizes of prey were determined by analyzing the food of nestlings. These data were evaluated in light of relative abundance of prey, which was based on fish collected in nearby tidal creeks. The majority of food items (43%) taken by the heron assembly consisted of a two species of nekton, Mummichog (Fundulus heteroclitus) and Grass Shrimp (Palaemonetes pugio). Among the day herons, dietary compositions overlapped to the extent expected if each individual was foraging randomly. The diet of the Black-crowned Night-Heron diverged significantly from those of the Snowy Egret and Tricolored Heron, but not from that of the Great Egret. Considering relative abundance of different sized Mummichogs, the lengths of dietary Mummichogs overlapped as expected between each heron species. The three day herons coincided in their use of feeding microhabitats, most of which were in the intertidal zone. I found no evidence of social foraging: group sizes of feeding herons were the same as those of herons engaged in other activities, and most birds foraged alone. Foraging birds were rarely aggressive. Similarities (overlaps) in resource exploitation, as measured by type and size of prey and by microhabitat use, were as expected under a null model. Only two of 15 pairwise overlaps were less than expected; two were greater than expected. The four heron species formed an assembly of opportunists, whose members took prey according to abundance. The results provide little evidence that the herons partitioned food resources in any significant way. The lack of competitive or cooperative interactions between herons may be related to the superabundance of a few prey species, a condition probably typical of most estuaries.
Compound heterozygosity for a frameshift mutation and an upstream deletion that reduces expression of SERPINH1 in siblings with a moderate form of osteogenesis imperfecta

SERPINH1 encodes the collagen chaperone HSP47 that binds to arginine‐rich sequences in the type I procollagen trimers and provides the final steps in the folding and stabilization of the triple helical domain. Loss of both alleles in mice results in very early embryonic lethality. SERPINH1 mutations have been associated with one of the rarest forms of recessively inherited osteogenesis imperfecta (OI) with a moderate to severe phenotype. We identified a family with non‐consanguineous unaffected parents who had two children with moderate short stature, low bone density, and fractures. Both children were compound heterozygotes for two mutations: a frameshift in the last exon that deleted the RER retention signal, and a 5,274 bp deletion 2.37 kb upstream from the transcription start site. The maternally‐inherited frameshift allele was expressed at normal levels, but the protein was unstable. The mRNA encoded by the second allele represented about 50% of that from the frameshift‐containing allele. The upstream deletion was inherited from the father, and the mRNA encoded by that allele in his cultured dermal fibroblasts was also expressed at a low level, which confirmed that this domain had a regulatory function for SERPINH1. Regulatory mutations are uncommon causes of human genetic disorders, and the ability to measure expression levels in appropriate cells is key to their identification.
NOISE REDUCTION IN THREE PHASE VOLTAGE SOURCE INVERTER FED IM USING RANDOM SVPWM TECHNIQUE

The paper focus to study on noise reduction of the line voltage of two level three phase voltage source inverter (VSI) fed induction motor (IM) at the specific frequency, and developed new PWM called Random Space Vector Pulse width modulation technique (RSVPWM) for reducing noise on line voltage. The developed RSVPWM is combining RPWM and Space vector modulation (SVPWM) technique. The paper also investigates the three-phase VSI fed induction motor and its noise behavior. The proposed method is able to create a gap in the spectrum of line voltage at selective frequency in human hearing range. Therefore, unlike conventional RPWM techniques, switching periods are determined based on the position of rotary reference vector. The paper compared with other PWM such as SPWM, RPWM and SVPWM. Among all PWM method the proposed RSVPWM generate higher voltages with low total harmonic distortion. The proposed RSVPWM is receipt less line voltage noise (10.4dB at lower modulation range and 9dB at higher modulation range). The simulation and experimentation is carried out for the full range of switching frequency of 1 kHz to 20 kHz. The modulation method can be used in both openand closed-loop IM drive such as V/F and vector control.
INVESTIGATION AND IMPLEMENTATION OF SOLAR PV BASED FORWARD MICROCONVERTER

Nowadays, many alternate solutions are there to overcome the traditional power grid blackout and it results in an increase in research on the various field. The solar photovoltaic (PV) powered microconverter is the way to increase the performance nowadays. The analysis and implementation of such converter are discussed in this paper. The various Maximum Power Point Tracking (MPPT) techniques are applied to the DC-DC converter to extract the maximum and optimal power from the PV panel. The main objective of this paper is to design a closed-loop DC-DC Converter to boost the voltage from the PV cell and supplied to the load with high efficiency. The converter selected in this paper is single ended primary inductor converter (SEPIC) converter and it offers low voltage stress on the switch and simple design. The switching loss is less due to single switch with low-frequency switching. The gating and commutation components are less and therefore the conduction loss is also less. The microconverter is analyzed and simulated for closedloop control and it concludes suitability of the converter for solar PV application. Finally, the prototype is developed for 80W and the results are verified experimentally.
Development of a Species-Specific PCR-Restriction Fragment Length Polymorphism Analysis Procedure for Identification ofMadurella mycetomatis

ABSTRACT Madurella mycetomatis is the commonest cause of eumycetoma in Sudan and other countries in tropical Africa. Currently, the early diagnosis of mycetoma is difficult. In attempting to improve the identification of M. mycetomatis and, consequently, the diagnosis of mycetoma, we have developed specific oligonucleotide primers based on the sequence of the internal transcribed spacer (ITS) regions spacing the genes encoding the fungal ribosomal RNAs. The ITS regions were amplified with universal primers and sequenced, and then two sets of species-specific primers were designed which specifically amplify parts of the ITS and the 5.8S ribosomal DNA gene. The new primers were tested for specificity with DNA isolated from human mycetoma lesions and DNA extracted from cultures of M. mycetomatis reference strains and related fungi as well as human DNA. To study the genetic variability of the ITS regions of M. mycetomatis, ITS amplicons were obtained from 25 different clinical isolates and subjected to restriction fragment length polymorphism (RFLP) analysis with CfoI, HaeIII,MspI, Sau3AI, RsaI, andSpeI restriction enzymes. RFLP analysis of the ITS region did not reveal even a single difference, indicating the homogeneity of the isolates analyzed during the current study.
Coexisting overwintering strategies in Daphnia pulex: A test of genetic differences and growth responses

We tested whether clones of Daphnia pulex in a mesotrophic lake differ with respect to overwintering strategies: either surviving the winter as parthenogenetic females with reduced metabolism in pelagic waters, or as sexually produced dormant embryos in ephippia. During winter 2007, we established two groups of clonal laboratory lines from females collected in the lake and neonates hatched from ephippia. Genetic relatedness and differentiation of the two clonal groups were studied with microsatellite markers, and compared to the genetic structure of a field reference population. Flow‐through experiments designed to measure the specific juvenile growth rate (gj) of individual clones (a good proxy of fitness) at low and at high food concentrations show that differences in gj indicate physiological adaptation of the different starting populations to improving food conditions in spring. Although gj differed significantly among individual clones, both below and above the incipient limiting food concentration, we found no significant differences between the clonal groups. There was considerable clonal variation for reaction norms of gj, but neither the group means of the slopes of reaction norms nor of the threshold food concentrations for growth differed significantly. The lack of differences in group means so far does not support the hypothesis that clones are specialized for either parthenogenetic or for dormant overwintering. It rather suggests a mixed strategy of individual females producing resting stages as insurance and then trying to survive the winter in an active state.

E-mail: gamze.erzin@gmail.com P: +90 312 5962000 Corresponding Author ORCID ID: https://orcid.org/0000-0001-8002-5053 Abstract Aim: The aim of this study is to investigate the symptom dimensions of patients with schizophrenia, who were grouped according to demographic variables, using BPRS. Materials and Methods: BPRS was applied to 199 patients who were diagnosed with schizophrenia. We divided the participants into three groups according to their ages as follows: (1) 18-34 (n=87; 43.72%), (2) 35-44 (n=56; 28.14%), (3) 45 and above (n=56; 28.14%). Principal component analysis with varimax rotation was used for exploratory factor analysis. The factors were selected on the basis of an eigenvalue > 1. Results: A five-factor solution was explaining the total variance in whole sample groups. In patients aged between 18-34 years, the PCA resulted in a five-factor solution explaining 69.20% of the total variance. In patients aged between 35-44 years, six factors were extracted accounting for 67.77% of the total variance. For patients aged 45 and above, a six-factor solution was evident explaining 67.91% of the total variance. Discussion: The items explained by the BPRS scale for ages between 18-34 years, between 35-44 years, and over 45 years were containing only the first 3 factors (positive, negative, and mania), and then differed particularly in the group over 45 years of age. Further studies are needed to support the findings of this study.

Identification of the EnteropathogensCampylobacter jejuni and Campylobacter coli Based on the cadF Virulence Gene and Its Product

ABSTRACT Campylobacter jejuni and Campylobacter coliare common causes of gastroenteritis in humans. Infection with C. jejuni or C. coli is commonly acquired by eating undercooked chicken. The goal of this study was to develop specific detection assays for C. jejuni and C. coliisolates based on the cadF virulence gene and its product. The cadF gene from C. jejuni and C. coli encodes a 37-kDa outer membrane protein that promotes the binding of these pathogens to intestinal epithelial cells. A fragment of approximately 400 bp was amplified from 38 of 40 (95%) C. jejuni isolates and 5 of 6 (83.3%) C. coli isolates with primers designed to amplify an internal fragment of thecadF gene. PCR was then used to amplifyCampylobacter DNA from store-bought chickens. A 400-bp band was amplified from 26 of the 27 chicken carcasses tested by the PCR-based assay. The CadF protein was detected in every C. jejuni and C. coli isolate tested, as judged by immunoblot analysis with a rabbit anti-C. jejuni 37-kDa serum. In addition, methanol-fixed samples of whole-cell C. jejuni and C. coli were detected with the rabbit anti-37-kDa serum by using an indirect-immunofluorescence microscopy assay. These findings indicate that the cadF gene and its product are conserved among C. jejuni and C. coli isolates and that a PCR assay based on the cadFgene may be useful for the detection of Campylobacterorganisms in food products.
Desiccation-induced changes in viability, lipid peroxidation and antioxidant enzyme activity in Mimusops elengi seeds

Intermediate seeds of Mimusopsis elengi showed obvious membrane lipid peroxidation during desiccation. When the moisture content (MC) decreased from initial 41.8 to 6.1%, seed viability significantly decreased from 100 to 23%, consorted with activity changes of a few anti-oxidative enzymes. The activities of superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX) and glutathione reductase (GR) gradually showed a similar change rend in the process of desiccation, namely their activities firstly increase to the maxima, and then decreased. The exception was catalase (CAT) which showed a general decrease in activity during the whole experimental period. It indicated that seed deterioration of M. elengi was related with uncontrolled production of reactive oxygen species (ROS) and the ability of enzymes mentioned to eliminate such toxic products during drying seeds. Thus, the fact that oxidative stress induced unmendable damage was considered as one of the critical factors which resulted in viability loss of M. elengi seeds. Keywords: Intermediate seeds, desiccation, reactive oxygen species, antioxidant enzymes, lipid peroxidation, Mimusops elengi
Prolate and oblate chiral liquid crystal spheroids

Mechanical strain, curvature, and elasticity lead to the emergence of exotic molecular configurations in chiral liquid crystals. Liquid crystals are known to exhibit intriguing textures and color patterns, with applications in display and optical technologies. This work focuses on chiral materials and examines the palette of morphologies that arises when microdroplets are deformed into nonspherical shapes in a controllable manner. Specifically, geometrical confinement and mechanical strain are used to manipulate orientational order, phase transitions, and topological defects that arise in chiral liquid crystal droplets. Inspired by processes encountered in nature, where insects and animals often rely on strain and temperature to alter the optical appearance of dispersed liquid crystalline elements, chiral droplets are dispersed in polymer films and deformation induced by uniaxial or biaxial stretching. Our measurements are interpreted by resorting to simulations of the corresponding systems, thereby providing an in-depth understanding of the morphologies that arise in these materials. The reported structures and assemblies offer potential for applications in smart coatings, smart fabrics, and wearable sensors.
A multistage voltage and power flow control of distribution systems in the presence of DGs

With the rapid increase of distributed generation (DG) in distribution systems, voltage and power flow become more liable to violate. The generation of non dispatchable DG is un_ controlled so traditional controllers such as on load tap changer (OLTC) are unable to keep the distribution system operating all times without violations. As a result voltage and power flow control should be adapted. This paper proposes a multistage method to control voltage and power flow in the system if any bus or line exceeds its voltage or thermal limit respectively. The first stage is the control of (OLTC) and then the reactive power control is applied and if the two last methods are insufficient to keep the system operating within accepted limits, active generated power curtailment is considered. The method proposed here considers the rated reactive power drawn from the transmission system that keeps the voltage of transmission buses within limits. This method is based on the Jacobian sensitivity matrix. This method is tested on IEEE 33 bus radial distribution system using matlab. The simulation is done using matpower5.1 package. Index Terms – distributed generation, voltage control, on load tap changer, reactive power control, energy curtailment.
The RNA Chaperone Hfq Is Required for Virulence of Bordetella pertussis

We recently became aware that since 2008, our laboratory has used a Bordetella pertussis strain that was erroneously labeled and referred to in this publication as Bordetella pertussis 18323. Single nucleotide polymorphism analysis and determination of the draft genome sequence of the strain performed by Dr. Harris at the Sanger Institute revealed that we have been working with the B. pertussis Tohama I strain. The genome sequence data for this strain (assembled sequence contigs) from the study named “Sequencing Czech Bordetella pertussis wP vaccine strains” can be downloaded from the ENA under study accession number ERP003836, using the following link: http://www.ebi. ac.uk/ena/data/view/SAMEA2177726.
COPPER LOSS MINIMIZATION WITH USING MODIFIED DIRECT TORQUE CONTROL METHOD IN SWITCHED RELUCTANCE MOTOR DRIVES

Switched reluctance motors are associated with such advantages as simple and robust structure, high reliability, and low cost. However, the high torque ripple is one of the major problems. Direct torque control (DTC) Method is widely used on ac machines, such as induction motors and permanent magnet motors. Pulsating torque in switched reluctance motors is high because of commutation. Implementation of DTC technique is simple with good accuracy. In this DTC method, switching strategy is modified and the torque ripple is significantly reduced by choosing the proper bandwidth of the output torque. Recently, a number of studies have been conducted on direct torque control for torque ripple reduction in SRM drives. This paper investigates the conventional DTC method from the standpoint of copper losses. In a second stage, an improved DTC method is proposed for reducing copper losses and increasing the SRM drive efficiency. The conventional DTC and the modified methods are finally compared and the simulation results are presented in MATLAB Simulink.
Malignant fibrous histiocytoma in a male breast: case report

Purely sarcomatous tumors of the breast are extremely uncommon; malignant fibrous histiocytoma (MFH), a type of sarcoma, can occur as a primary lesion in breast parenchyma. Pre-operative diagnosis is possible with immunohistochemical staining for vimentin; with attention to morphologic details; and with immunohistochemistry, misdiagnosis is avoided. Breast cancer is rarely seen in males, accounts for approximately 1% of all breast cancer cases, and breast sarcomas constitute less than 1% of breast tumors in both sexes. Here, we present a-74-year old male patient with MFH diagnosis, who reported a rapidly growing painless lump in his left breast. The mass was firm to palpation and no cutaneous changes were noted. Core needle biopsy revealed the presence of neoplastic cells, with pleomorphic atypical cells with large and irregular nuclei, high mitotic index, high fraction of ki-67—30%, immunoreactive to vimentin only. The patient underwent radical mastectomy. The final pathologic evaluation revealed a highly cellular tumor with spindle cells that have a storiform pattern; the diagnosis was MFH pT3 pN0(sn) according to the AJCC (8 edition, 2017) TNMG staging. Following radical mastectomy, the patient was given adjuvant radiotherapy. The patient, after 65 months, died for bronchopulmonary compliances without local recurrences and/or metastases. According to limited experience previous reported in medical literature, while mastectomy could be considered the best choice in male MFH, sentinel lymph nodes biopsy was first reported in our case. Adjuvant radiotherapy should be evaluated based on residual neoplastic cells on surgical margins or maximum cancer diameter. In light of its rarity, MFH treatment algorithm should be shared by multidisciplinary breast cancer team. Our experience supports the clinical decision making in MFH male
Rapid Identification of Fungi by Using the ITS2 Genetic Region and an Automated Fluorescent Capillary Electrophoresis System

ABSTRACT Invasive fungal disease often plays an important role in the morbidity and mortality of immunocompromised patients. The poor sensitivity of current fungal blood culture and histological practices has led to the development of highly sensitive and specific molecular techniques, such as the PCR. Sequence variability of the internal transcribed spacer 2 (ITS2) region of fungi is potentially useful in rapid and accurate diagnosis of clinical fungal isolates. PCR with fungus-specific primers targeted toward conserved sequences of the 5.8S and 28S ribosomal DNA (rDNA) results in amplification of the species-specific ITS2 regions, which are variable in amplicon length. We have made use of the ABI PRISM 310 genetic analyzer and the ABI PRISM 310 GeneScan analysis software for the determination of variable size differences of the ITS2 region of clinically important fungi, including Candida and non-Candida yeasts,Aspergillus species, and a variety of dermatophytes. No cross-reaction occurred when samples were tested against human and bacterial genomic DNA. We have found that most clinically significant fungal isolates can be differentiated by this method, and it therefore serves to be a promising tool for the rapid (<7 h) diagnosis of fungemia and other invasive fungal infections.
