Association Between Sugarbeet Root Yield and Sugarbeet Root Maggot (Diptera: Otitidae) Damage

Sugarbeet root maggot, Tetanops myopaeformis von Roder, is a major insect pest of sugarbeet throughout much of North America. Root maggot damage is routinely rated on a 0 (no damage) to 5 (severe damage) scale. In 42 trials, the relationship between visual damage and root yield was examined. The mean damage rating in the absence of insecticides was 3.3± 0.4, compared with 1.7 + 0.7 for the highest yielding treatment in each trial. Mean root yield of the highest yielding treatment in each trial was 48.8± 8.9 Mg ha -1 , compared with a mean of 29.0 ±12.5 Mg ha -1 when no insecticides were applied. Regression analyses within individual trials indicated that the yield loss associated with each increment of the damage rating scale fluctuated widely, ranging from near 0 to 15.7 ±2.42 Mg ha -1 . The percent yield reduction in the absence of insecticides ranged from 9.8 to 83.6% when compared with the treatment providing the most effective control in each test. These results are useful in estimating losses, developing recommendations, and providing a standard of comparison for alternative control strategies.
KNOWLEDGE AND PRACTICE ON TUBERCULOSIS INFECTION CONTROL AMONG GOVERNMENT PRIMARY HEALTHCARE WORKERS IN A DISTRICT IN MALAYSIA

Background: Tuberculosis (TB) is the leading cause of mortality among infectious diseases in the world. Healthcare workers (HCWs) are among the high-risk group infected by TB with double prevalence than the general population due to inadequate TB infection control (TBIC). In Malaysia, TB cases among HCWs have increased, but the TBIC knowledge and practice remain poor. This research aimed to determine the TBIC knowledge and practice among HCWs and the predictors of good knowledge and practice of TBIC. Materials and Methods: This study is a cross-sectional study with a random sampling of HCWs from 13 primary healthcare facilities in a district in Malaysia. A self-administered questionnaire was used in this study, adapted from similar studies in Ethiopia and Uganda. Simple and multiple logistic regressions were used as statistical analysis. Result: The response rate of this study was 77% (320 respondents). The percentages of respondents having good TBIC knowledge and practice were 70.6% and 51.6% respectively. The significant predictors of good TBIC knowledge were the diploma educational level, (AOR=2.325, 95%CI=1.145-4.722), family history of TB infection (AOR=3.882, 95% CI=1.021-14.765), doctor (AOR=5.022, 95%CI=1.224-20.600) and worked in an outpatient clinic (AOR=4.504, 95%CI=2.050-9.892). Meanwhile, the diploma holder (AOR=2.055, 95%CI=1.065-3.964), married or widow (AOR=2.616, 95%CI=1.487-4.603) and working in maternal and child health clinic (AOR=3.479, 95%CI=1.700-7.118) were the predictors of good TBIC practice. Conclusion: The practice of TBIC among the respondents was inadequate despite good knowledge. Training that emphasises on hands-on skill needs to be strengthened to ensure proper knowledge as well as practice on TBIC. Keywords: Tuberculosis infection control, knowledge, practice, healthcare workers.

Small clutch sizes as a possible adaptation against ectoparasitism: a comparative analysis

Clutch size is expected to decrease with an increased rate of ectoparasite infestation. In order to test this hypothesis, I carried out comparative analyses using Australian and North American passerines. The allometry method showed a trend for passerine families which have higher degrees of ectoparasitism to also have smaller clutches. In the North American sample, however, the trend was confirmed for mite prevalence but was not for fly relative density. I also analyzed both samples using a method of independent comparisons. Results for Australian passerines suggest that an evolutionary change of clutch size in one direction is associated with an evolutionary change of relative density of ectoparasites in the opposite direction, after controlling for the effects of evolutionary changes in body size. The method of independent comparisons produced non-significant results for the North American sample. The hypothesis was also supported by a direct comparison of Australian and North American passerine families: Australian passerines lay smaller clutches than their North American counterparts and are infested more with contagious ectoparasites.
Bio-inspired crossover and a model for neuronal reprogramming

Bio-inspired crossover:Natural genomes are affected by various kinds of mutations, manifesting as variations in the genome. This includes modifications to individual base pairs (single nucleotide polymorphism, SNP), but also short insertions and deletions (indels), and variations in the position (translocations) or multiplicity (copy number variations) of genetic sequences. While SNPs are historically the most studied, the other, structural variations are now known to affect a large fraction of the human genome, and can result in clinically relevant expressions in the phenotype. In biology, structural variations are also known to affect evolutionary dynamics of a population. For example, most genes originate through duplication, followed by divergent evolution of the two copies. However, in computer programs simulating evolution, structural variations are rarely included. Their absence makes it difficult to study the evolutionary consequences of translocation and copy number variation in simulated models. Including them may also have positive consequences for bio-inspired computation such as genetic algorithms. In this dissertation, a theoretical framework with algorithmic implementations is presented for sexual reproduction between linear genomes structures with structural variation, including permutations, and DNA-like strings.A model of neuronal reprogramming:In multicellular organisms, cells typically follow a hierarchical progression from embryonal stem cells to increasingly specialised cell types. However, by manipulating the expression of key genes, it is possible to reverse this specialisation, or convert directly between terminal cell types. This technology has been applied to convert human skin cells to neurons, with promising applications in disease modelling and regenerative medicine. Understanding the gene regulation network (GRN) governing this transition is crucial for improving the efficiency of this conversion in the future. In this dissertation, we integrated known interactions described in the literature into a holistic GRN model. We measured the activity of genes that are known to play pivotal roles during a reprogramming process, and compared these data to our modelling system. We found that the reprogramming process could be accurately modelled. The interaction between two genes, PTB and nPTB, played a different role from its usual interpretation in the literature, acting as a negative feedback loop. (Less)

Expression of α-smooth muscle actin in human's thoracic aorta dissection.

Objective:To explore the relationship of α-smooth muscle actin(α-SMA) in human's thoracic aorta dissection(TAD). Methods:Tissue samples of dissected thoracic aorta(DA) and normal thoracic aorta(NA) were evaluated.Western Blotting and immunohistochemical studies were performed to detected α-SMA expression in tissues.Results:α-SMA expression was apparently downregulated in DA group,while proliferated phenotype was predominated among vascular smooth muscle cells.Conclusion:Expression of α-SMA was mainly downregulated in VSMC of vascular media wall.Phenotype change of VSMC was occurred sent so that elasticity of the media was lack and dissection of vascular was performed.Therefore,α-SMA might play a key role in the development of human's thoracic aorta dissection,which is need to be further explored.
DBSCAN OPTIMIZATION FOR IMPROVING MARINE TRAJECTORY CLUSTERING AND ANOMALY DETECTION

Abstract. Today maritime transportation represents 90% of international trade volume and there are more than 50,000 vessels sailing the ocean every day. Therefore, reducing maritime transportation security risks by systematically modelling and surveillance should be of high priority in the maritime domain. By statistics, majority of maritime accidents are caused by human error due to fatigue or misjudgment. Auto-vessels equipped with autonomous and semi-autonomous systems can reduce the reliance on human’s intervention, thus make maritime navigation safer. This paper presents a clustering method for route planning and trajectory anomalies detection, which are the essential part of auto-vessel system design and development. In this paper, we present the development of an enhanced density-based spatial clustering (DBSCAN) method that can be applied on historical or real-time Automatic Identification System (AIS) data, so that vessel routes can be modelled, and the trajectories’ anomalies can be detected. The proposed methodology is based on developing an optimized trajectory clustering approach in two stages. Firstly, to increase the attribute dimension of the vessel’s positioning data, therefore other characteristics such as velocity and direction are considered in the clustering process along with geospatial information. Secondly, the DBSCAN clustering model has been enhanced by introducing the Mahalanobis Distance metric considering the correlations of the position cluster points aiming to make the identification process more accurate as well as reducing the computational cost.
Morphology of the Reproductive and Alimentary Systems of the Aradoidea (Hemiptera), with Comments on Relationships within the Superfamily

Reproductive and alimentary structures were studied in 24 species representing 14 genera of 5 subfamilies of Aradidae and in 1 species in 1 of the 2 known genera of Termitaphididae, and external female genitalia were studied in representatives of all 8 aradid subfamilies and in the termitaphidid species. Most Aradoidea were found to have a very primitive bulbus ejaculatorius with only 2 epithelial layers, corresponding to the middle and inner layers of the complex bulbus of other land bugs. In some Aradidae, however, the bulbus is 3-layered in its posterior region. Ovaries and testes were most frequently found to have 5 ovarioles and follicles, respectively, but the numbers of both ranged from 2 to 6. A small rectal diverticulum was found in Prosympiestinae, and a well-developed one in Carventinae and Mezirinae. On the basis of retention of several primitive features in the reproductive and alimentary organs, the Aradoidea are regarded as representing a very early offshoot in the evolution of terrestrial Heteroptera that became specialized for a sedentary and mycetophagous mode of life. The current classification of the superfamily Aradoidea (Usinger and Matsuda 1959. Classification of the Aradidae (Hemiptera-Heteroptera). British Museum (Natural History), London) is generally supported, but apparently the Carventinae and the Mezirinae should be combined into a single subfamily. The Termitaphididae do not seem sufficiently distinct from the various aradid subfamilies to warrant family status. The female ectodermal genital duct and the ovipositor of the various groups are compared and some generalizations concerning the latter are given.
Parental Psychological Control, Big Five Personality and Difficulties in Emotion Regulation among Adolescents

Introduction: The study aims to examine the big five personality (Dimensions) as a mediator between Parental Psychological Control (PPC) and Difficulties in Emotion Regulation (DER). It was also researched that child characteristics moderate the effects of parenting outcomes. Method: Three hundred adolescents studying in different schools in Delhi were selected based on the random sampling technique. Three scales, namely Psychological Control Scale—Youth Self-Report (PCS-YSR), Big Five Inventory (BFI), and Difficulties in Emotion Regulation Scale Short Form (DERS-SF) were administered. A dichotomous independent variable (named X1) was used in the research where PPC was divided into two groups 'Both High' group VS 'Others'. Results: Obtained scores were analyzed by using Parallel mediation analysis through PROCESS macro version 3.2. 01 for SPSS created by Hayes in 2018. Results of the mediational analysis revealed that X1(Both High vs. Others) significantly predicted neuroticism, and X1, neuroticism, and openness significantly predicted DER. Total effect (c=3.78, p<.05) and direct effect (c=2.73, p<.05) were found to be significant. Indirect effects were obtained by the Bootstrapping method. Findings revealed a specific indirect effect of neuroticism to be significant (coeff. =.1075; LLCI-ULCI= .0077 to.2102). Conclusion: Neuroticism significantly mediates the relationship between emotion regulation and PPC. It is necessary to incorporate both individual and environmental factors to understand emotional development processes. It is therefore suggested to develop interventions that not only helps adolescents to learn effective ways to regulate emotions but to also guide parents to cater to the child's emotional needs effectually.
Mean Level and Variability of Arterial Blood Pressure in Unanesthetized Rabbits

意識下,無拘束下のウサギについて,6時間にわたり平均血圧(MAP6h)を測定し,その平均値および変動性を検討するとともに,合わせて3分間の平均血圧(MAP3m)のそれらと比較検討した. 左鎖骨下動脈よりカテーテルを大動脈弓に慢性的に留置した9匹の健康なウサギの平均血圧を,トランスデューサおよびA/D変換器を介して1秒ごとに約6時間,コンピュータでサンプリングした. MAP6hの各記録における平均値および標準偏差は,それぞれ73. 4～99.2mmHg,5.7～10. 0mmHgと広範囲に分布したが,標準偏差は平均値の増大につれて有意な減少を示した(P<0.01). 各記録において,MAP3mの平均値とMAP6hの平均値にはほとんど差が認められなかったが,分散はMAP3mの方が有意に小さかった(P<0.01). 18例中9例において,MAP6hのヒストグラムは正規分布を示さず,最頻値での尖鋭化,右方への偏位,さらに2峰性の分布も認められた. MAP3mのヒストグラムは,ウサギが安静状態にあるときは,ほとんどが正規分布を示したが,体動にともない左右への偏位がみられた. 上記の結果より,圧反射系は血圧が正常レベル(90mmHg付近)にあるとぎに最もその機能を発揮し,また,短時間(3分間)の血圧調節機能は,長時間(6時間)のそれより強力であると考えた.
On the exact quantum query complexity of MODmn and EXACTk, ln

The query model has generated considerable interest in both classical and quantum computing communities. Typically, quantum advantages are demonstrated by showcasing a quantum algorithm with a better query complexity compared to its classical counterpart. Exact quantum query algorithms play a pivotal role in developing quantum algorithms. For example, the Deutsch-Jozsa algorithm demonstrated exponential quantum advantages over classical deterministic algorithms. As an important complexity measure, exact quantum query complexity describes the minimum number of queries required to solve a specific problem exactly using a quantum algorithm. In this paper, we consider the exact quantum query complexity of the following two $n$-bit symmetric functions $\text{MOD}_m^n:\{0,1\}^n \rightarrow \{0,. ,m-1\}$ and $\text{EXACT}_{k,l}^n:\{0,1\}^n \rightarrow \{0,1\}$, which are defined as $\text{MOD}_m^n(x) = |x| \bmod m$ and $ \text{EXACT}_{k,l}^n(x) = 1$ iff $|x| \in \{k,l\}$, where $|x|$ is the number of $1$'s in $x$. Our results are as follows: i) We present an optimal quantum algorithm for computing $\text{MOD}_m^n$, achieving a query complexity of $\lceil n(1-\frac{1}{m}) \rceil$ for $1<m \le n$. This settles a conjecture proposed by Cornelissen, Mande, Ozols and de Wolf (2021). Based on this algorithm, we show the exact quantum query complexity of a broad class of symmetric functions that map $\{0,1\}^n$ to a finite set $X$ is less than $n$. ii) When $l-k \ge 2$, we give an optimal exact quantum query algorithm to compute $\text{EXACT}_{k,l}^n$ for the case $k=0$ or $k=1,l=n-1$. This resolves the conjecture proposed by Ambainis, Iraids and Nagaj (2017) partially.
Preparation and characterization of p-sulfonated calix[4]arene functionalized chitosan hydrogel beads and their preliminary adsorption study towards removal of lead(II) and zinc(II) ions

p- sulfonated calix[4]arene functionalized chitosan hydrogel beads have been successfully prepared by mixing p- sulfonated calix[4]arene and chitosan in dilute acetic acid solution (1% v/v), followed by dropping the mixture into sodium hydroxide solution to form beads with diameters of ~0.1 cm. The presence of the active sulfonate groups and the unique structure of calixarene render the material useful as an adsorbent for heavy metal ions. Metal adsorption on p- sulfonated calix[4]arene is possible through a combination of physical and ionic interactions. Atomic Absorption Spectroscopy (AAS) results showed that the amount of adsorbed metal ion is optimum at 10 ppm for all samples. The overall percentage of metal ion removal shows that p- sulfonated calix[4]arene modified chitosan is the best adsorbent with up to 98% removal achieved for Pb(II) and 90% removal for Zn(II). This is followed by p- sulfonated calix[4]arene and graphene oxide (GO) modified chitosan with up to 90% removal for Pb(II) and 89% removal for Zn(II) and pure chitosan hydrogel beads with up to 60% removal for both Pb(II) and Zn(II). The results clearly prove that the presence of p- sulfonated calix[4]arene can enhance the adsorption of heavy metal ions. In addition, the adsorbent shows higher Pb(II) removal compared to Zn(II).
Effect of Human Umbilical Cord Derived Mononuclear Cells Transplantation on Ovarian Dysfunction Caused by Methotrexate in Female Rats

Background: A search for methods to prevent infertility in patients receiving chemotherapy including methotrexate is important. Cell therapies with human embryonic and specific adult stem cells have emerged as an alternative management for various diseases. Aim: to study the effect of human umbilical cord derived mononuclear cells transplantation on ovarian dysfunction caused by methotrexate in female rats. Methods: the effect of mono nuclear cells (MNCs) treatment (IV injection once in the tail vein for diabetic rats in a dose of 150 × 10 MNCs cells/rat) on ovary and uterus pathology, malondialdehyde (MDA) level in ovary and follicle stimulating hormone (FSH) level was assessed after methotrexate treatment. Results: Treatment with MNCs in rats pretreated with methotrexate significantly improved all parameters measured (body weight, ratio between ovary and body weight, ratio between uterus and body weight), level of MDA in ovary tissue, FSH and histopathology of ovary and uterus as compared to methotrexate only treated rats. Conclusion: These data indicate that MNCs treatment improved ovarian dysfunction associated with methotrexate therapy.
Co-occurring and opposing freshwater inflow effects on phytoplankton biomass, productivity and community composition of Galveston Bay, USA

Freshwater inflow effects on phytoplankton have long interested aquatic ecologists. More recently, timing and magnitude of inflow events have been a focus as they can be strong drivers of phytoplankton diversity and productivity. In the present research, we empirically and theoretically explored the effects of inflow events on phytoplankton of Galveston Bay, Texas, a bay system whose freshwater inflow arises primarily from 2 rivers, the San Jacinto and Trinity. We found that conditions in the upper regions of Galveston Bay adjacent to these rivers had opposing influences on phytoplankton. In the region near the San Jacinto River, inflows mostly stimulated biomass and productivity, while in the region near the Trinity River, inflows had the opposite effect. This suggested that the phytoplankton reproductive growth rate was at times nutrient limited near the San Jacinto River and that population growth responded rapidly to nutrient loadings. This also suggested that population growth was controlled at times by other processes near the Trinity River, thereby negating the effects of nutrient loadings. Decreased phytoplankton biomass occurred in this region due, in part, to hydraulic displacement. These co-occurring and opposing inflow effects extended into the midand lower bay regions, but the extension varied in time and location with no seasonal trend. Such observations underscore the challenges of predicting system responses to altered inflows. Phytoplankton composition was also affected by inflows, and some taxonomic trends were regionally specific. Attributes of phytoplankton relating to use of alternative sources of nutrition, differential growth rates and immigration of euryhaline species from rivers likely influenced the spatiotemporal distribution of taxa.
1. Insects – A Natural Nutrient Source for Poultry – A Review

Abstract The consumption of poultry meat and eggs is expected to increase considerably in the nearest future, which creates the demand for new poultry feed ingredients in order to support sustainable intensive production. Moreover, the constant improvement of the genetic potential of poultry has resulted in an increased nutrient density in poultry feeds, which limits the possibility to include low quality feed ingredients. Therefore, the feed industry needs new sources of highly digestible protein with a desirable amino acid composition to substitute other valuable but limited protein sources of animal origin, such as fishmeal. With estimated 1.5 to 3 million species, the class of insects harbours the largest species variety in the world including species providing a high protein and sulphur amino acids content, which can be successfully exploited as feed for poultry. The aim of this paper is to review the present state of knowledge concerning the use of insect protein in poultry nutrition and the possibilities of mass production of insects for the feed industry. There is no doubt that insects have an enormous potential as a source of nutrients (protein) and active substances (polyunsaturated fatty acids, antimicrobial peptides) for poultry. It can be concluded, based on many experimental results, that meals from insects being members of the orders Diptera (black soldier fly, housefly), Coleoptera (mealworms) and Orthoptera (grasshoppers, locust, crickets and katylids), may be successfully used as feed material in poultry diets. However, legislation barriers in the European Union, as well as relatively high costs and limited quantity of produced insects are restrictions in the large-scale use of insect meals in poultry nutrition.
