PARENTS ’ EDUCATIONAL BACKGROUND AND DEVIANT BEHAVIOURS OF FEDERAL UNIVERSITIES UNDERGRADUATES IN SOUTH-SOUTH GEOPOLITICAL ZONE OF NIGERIA

The purpose of this study was to investigate the influence of parental educational background on students ’ deviant behaviours in Federal universities in the south-south geopolitical zone of Nigeria. The design adopted for this study was the descriptive survey design. The main instrument used for data collection was the “ Parental Educational Background on Deviant Behaviour Questionnaire (PEBDEBEQ). Multi-staged sampling technique was used in selecting the representative sample size of 1,524 students drawn from the population. Data were analyzed using One-Way Analysis of Variance (ANOVA). The hypothesis was tested at 5% level of significance. The findings revealed that parents who are relatively higher in level of education tend to transmit discipline culture and values to their children and also they make the home environment favourable to their children by meeting their needs. Conclusion was that parental education influences the discipline behaviour of students. Based on the findings, it was recommended among others that both governmental and non-governmental organizations should be involved in non-formal education programmes that will enhance the educational level of parents.
Blasting bridges and culverts: Water overpressure and vibration effects on fish and habitat

Water overpressures and ground vibrations from blasting may injure or kill salmonid fish in streams and embryos in streambeds. Explosives are used to remove failing structures in remote areas of the Tongass National Forest that impair watershed function. The State of Alaska Department of Fish and Game standards limit blast induced water overpressures to 2.7 lb/in (18.6 kPa) and streambed vibrations to 0.5 in/s (13 mm/s) when embryos are present. Researchers, however, have reported salmonid mortality from pressures only as low as 12.3 and 19.3 lbs/in (85 and 133 kPa) and embryo mortality from vibrations as low as 5.75 in/s (146 mm/s). I recorded in-stream overpressures and streambed vibrations with hydrophones and geophones at various distances from log bridge, log culvert, and metal culvert blasts. Peak water pressures (lb/in) were directly related to cube-root scaled distances with an attenuation rate of 1.51. Peak particle velocities in gravel were directly related to square-root scaled distances (SRSD, ft/lb) with an attenuation rate of -0.75. Water pressures were less than 7.1 lb/in (49.0 kPa) in all but one blast, and streambed vibrations did not exceed 5.5 in/s in gravel streambeds. State standards should be revised to reflect reported mortality and these observations of blasts in streams.
Indole-3-acetic Acid Production by Streptomyces sp Isolated from Rhizospheric Soils of Medicinal Plants

A total of 50 Streptomyces sp. isolates were obtained from rhizospheric soil of six medicinal plants. All the isolates were screened for their potential to produce IAA and 32 (64 %) isolates were able to utilize tryptophan and produce the IAA in the range of 11.40±0.1-90.33±0.50 µg/ml. Highest amount of IAA was produced by Streptomyces TL-10 recovered from rhizospheric soils of Ocimum sanctum and Streptomyces CR-2, an isolate of Cathranthus roseus was producing minimum amount of IAA. Sequencing of 16S rDNA genes of the Streptomyces sp.TL-10 isolate had 16SrDNA gene with 99% nucleotides identity to that Streptomyces sp. VITTKGB available in Genbank database. The IAA production was maximum (110.3±1.5 µg/ml) when the strain TL-10 was cultivated in a yeast malt extract broth amended with 2 mg/ml of L-tryptophan at pH 7.0, and incubated at 30°C with shaking at 125 rpm for 3 d. The culture filtrate from the strain TL-10 was found to stimulate significantly the root elongation of chickpea and tomato. These results suggest that IAA-producing Streptomyces TL-10 could be a promising candidate for utilization in growth improvement of plants of economic and agricultural value.

Effects of Phase Angle and Sensor Properties on On-Orbit Debris Detection Using Commercial Star Trackers

The recent proliferation of resident space objects (RSOs) in low Earth orbit (LEO) threatens the sustainability of space as a resource and requires persistent monitoring to avoid collisions involving valuable space assets. State-of-the-art ground-based space surveillance techniques, due to their susceptibility to atmosphere, weather, and lighting conditions, tend to focus on RSOs with characteristic length greater than 10 cm. Consequently, millions of smaller LEO RSOs remain untracked by ground-based methods, which reduces overall space situational awareness. Onboard satellite sensors offer a space-based method fortracking RSOs. Prior research has investigated the feasibility of using commercial star trackers (CSTs)—optical sensors prevalent on most active spacecraft—to observe, detect, and estimate the position and velocity of RSOs larger than 10 cm. In a recent effort, we expanded on these feasibility studies by assessing the capabilities of CSTs to detect debris particles smaller than 10 cm in characteristic length. In this paper, we extend our previous study by relaxing its zero-phase-angle assumption and characterizing the effect of Sun-RSO-CST phase angle on debris detection range. We identify a number of representative CSTs with publicly available optical characteristics and consider the effects of properties such as pixel pitch, diffraction limit, aperture diameter, and field of view (FOV) on the capability of each CST to detect debris at a given distance and relative velocity (in the form of streak speed). We find that, for debris particles modeled as diffuse Lambertian spheres, Sun-RSO-CST phase angles as high as 57 ◦ result in no more than 20% reduction to the useful RSO-CST detection range, and streak speed may serve as a stronger limiting factor for smaller debris particles than for larger ones. Though we identify find a general reduction in the feasible region, the results indicate that CSTs have the potential to substantially enhance space-based debris detection.
Quality of Effective Field Trips in Learning Agriculture in Secondary Schools in Rarieda Sub-County, Kenya

: Field trips must be well planned, for students to realize their cognitive and affective benefits as well as the opportunity to enjoy and explore an outdoor environment. Literature has shown that there are challenges of outdoor educational activities. Thus, the purpose of this study was to establish the perceptions of agriculture teachers and students towards quality of effective field trips in learning agriculture in secondary schools. A total of 22 agriculture teachers and 380 agriculture students from Boys Boarding, Girls Boarding, Mixed Day/Boarding and Mixed Day secondary schools from 17 secondary schools in Rarieda Sub-County of Kenya were sampled to participate in the study. Cluster sampling procedure was employed. Data on perceptions were collected using questionnaires. Data was analyzed using descriptive statistics (mean and standard deviation) and analysis of variance (ANOVA). The results showed that the respondents had a positive perception towards all the items. The positive perceptions implied that the components of field trips investigated has an influence on an effective agricultural field trip. Majority of the respondents had a view that agricultural field trips should involve active student engagement and evaluation of the students after the trip. There was no statistically significant difference in teachers’ perceptions on quality of effective agricultural field trip and selected characteristics: professional qualification and years of teaching experience. The study recommends that agriculture teachers should embrace the quality indicators established in order to maximize learning during the field trips.
The Impact of Chewing Khat during Pregnancy on Foetal Death History

: Chewing the leaves of Khat, a natural stimulant from the Catha Edulis plant, is a social habit in Yemen and East African countries. The aim of study to determine the effect of chewing khat during pregnancy on the history of foetus death in Sana'a city, Yemen. The sample was consisted of mothers attending the Primary Health Care Centre in Sana'a City and who had children less than two years of age, about 36% of them chewing khat during pregnancy. About 44% of pregnant mother’s chewer khat had history of foetus death as compared to 34% non-chewers khat, the difference was significantly associated. In addition, risk of pregnant mothers chewing khat regularly to have foetuses death was about 4 times as compared to non-chewers (p<0.05).
Evaluating the spatial transferability and temporal repeatability of remote-sensing-based lake water quality retrieval algorithms at the European scale: a meta-analysis approach

Many studies have shown the considerable potential for the application of remote-sensing-based methods for deriving estimates of lake water quality. However, the reliable application of these methods across time and space is complicated by the diversity of lake types, sensor configuration, and the multitude of different algorithms proposed. This study tested one operational and 46 empirical algorithms sourced from the peer-reviewed literature that have individually shown potential for estimating lake water quality properties in the form of chlorophyll-a (algal biomass) and Secchi disc depth (SDD) (water transparency) in independent studies. Nearly half (19) of the algorithms were unsuitable for use with the remote-sensing data available for this study. The remaining 28 were assessed using the Terra/Aqua satellite archive to identify the best performing algorithms in terms of accuracy and transferability within the period 2001–2004 in four test lakes, namely Vänern, Vättern, Geneva, and Balaton. These lakes represent the broad continuum of large European lake types, varying in terms of eco-region (latitude/longitude and altitude), morphology, mixing regime, and trophic status. All algorithms were tested for each lake separately and combined to assess the degree of their applicability in ecologically different sites. None of the algorithms assessed in this study exhibited promise when all four lakes were combined into a single data set and most algorithms performed poorly even for specific lake types. A chlorophyll-a retrieval algorithm originally developed for eutrophic lakes showed the most promising results (R2 = 0.59) in oligotrophic lakes. Two SDD retrieval algorithms, one originally developed for turbid lakes and the other for lakes with various characteristics, exhibited promising results in relatively less turbid lakes (R2 = 0.62 and 0.76, respectively). The results presented here highlight the complexity associated with remotely sensed lake water quality estimates and the high degree of uncertainty due to various limitations, including the lake water optical properties and the choice of methods.

The objective of the article is to analyze the impact of cross-border retail trade by estimating spending by sector on both sides of the Ciudad Juárez-El Paso cross-border conurbation. The expenditure estimation was done with the information provided by the cross-border survey of international bridge users, during the period October-December 2019. The results show that expenditures made by residents in Mexico who crossed into the United States were 177.7 million usd and those in the United States who crossed into Mexico 141.2 million, during the last quarter of 2019. Residents in Mexico indicate that their main reasons for crossing are shopping, work and school and U.S. residents to attend family reunions, medical or dental consultation and purchase medicine. Therefore, it is concluded that integration between the two cities is partial
Complex Microbial Mat Communities Used to Assess Primer Complex Microbial Mat Communities Used to Assess Primer Selection for Targeted Amplicon Surveys Selection for Targeted Amplicon Surveys

The microbiota of hydrothermal vents has been widely implicated in the dynamics of oceanic biogeochemical cycling. Lithotrophic organisms utilize reduced chemicals in the vent effluent for energy, which fuels carbon fixation, and their metabolic byproducts can then support higher trophic levels and high-biomass ecosystems. However, despite the important role these microorganisms play in our oceans, they are difficult to study. Most are resistant to culturing in a lab setting, so culture-independent methods are necessary to examine community composition. Targeted amplicon surveying, in which a marker gene is selected for DNA amplification, has become the standard practice for assessing the structure and diversity of hydrothermal vent microbial communities. The most commonly used marker gene is the small subunit ribosomal RNA (SSU rRNA) gene, due to its ubiquity across all cellular organisms and the presence of both conserved and variable regions. Here, the performance of primer pairs targeting the V3V4 and V4V5 variable regions of the SSU rRNA gene were assessed using environmental samples from microbial mats surrounding iron-dominated hydrothermal vents. Using the amplicon sequence variant (ASV) approach to taxonomic identification, the structure and diversity of microbial communities at Kamaʻehuakanaloa Seamount were elucidated in detail. Both primer pairs generated robust data and comparable alpha diversity profiles. However, several distinct differences in community composition were identified between primer sets, including differential relative abundances of both bacterial and archaeal phyla. The primer choice was determined to be a significant driver of variation among the taxonomic profiles generated. Based on the higher quality of the raw sequences generated and on the breadth of abundant taxa found using the V4V5 primer set, it is determined as the most efficacious primer pair for whole-community surveys of microbial mats at iron-dominated hydrothermal vents.
Evaluation of Tuberculosis Surveillance System in Akatsi District of Ghana

: The study was carried out in Akatsi District in Ghana with estimated population of 117,164. The objective of the TB surveillance system was to detect early persons with infectious lung disease and treat them to reduce transmission. The TB surveillance system was evaluated to describe the operation and performance of the system using system attributes. The evaluation was conducted using the “Updated Guidelines for Evaluating Public Health Surveillance Systems’’ of the Centers for Disease Control and Prevention (CDC). The Akatsi District TB surveillance system was useful and data was used for informed decision making. The system was simple, flexible and acceptable to most of the stakeholders. Data quality was good and all cases of TB were reported to the district public health office. The system was stable but its stability was threatened by occasional delay in providing sputum microscopy results. It is limited by low representativeness of the system and untimely dissemination of surveillance data to stakeholders. The system operation, availability and representativeness could be improved by opening additional TB diagnostic centres and training more laboratory staff in sputum microscopy.
Correlation between Socio-economic Status and Spontaneous Premature Birth: Nursing Teaching brochure

: Spontaneous preterm birth is a multi-factorial process. Low socioeconomic status (SES) considered as one of those factors. It has been associated with an increased risk of preterm birth, although the relationship varies by SES factors and not quiet identifiable. The aims were to assess the Correlation between socio-economic status and spontaneous premature birth design and provided nursing teaching brochure. A cross sectional research-design on purposive sample of 300 women at Women’s Health Hospital, Assuit University. A structure interviewing questionnaire for data collection, socioeconomic status data scale and the nursing education brochure were used. Results: Sixty percentages of women had a threatened preterm labor, while 40% had inevitable preterm labor. In addition, nearly two thirds of the studied women (65.67%) were in the age group 21-30 years. The results indicate that (75.3%) of the studied women were moderate socioeconomic level. In addition, results showed that the majority of mothers (90.7%) were house wives with a statistically significant difference of gestational age and socioeconomic status at level (P<0.002). There was a statistically significant difference (P<0.05) in both threatened and inevitable preterm birth and household crowding index. Conclusions: There is no an association or relationship between preterm labor and socioeconomic status evidenced with any statistical significant difference. Recommendations: Health education programs should be organized for pregnant women about the causes of preterm birth and risk factors leading to it, and also to the symptoms of premature birth.
14 th ANNUAL GRADUATE STUDENT SYMPOSIUM

Filters are integral components in communication systems that allow signals within a selected range of frequencies from the receiver antenna to be decoded. When communication systems encounter a high-power threat, it can potentially damage the power-sensitive components. This paper proposes a solution by designing an integrated filter-limiter topology using plasma technology. The proposed device acts as a bandpass filter at low input power levels, thus allowing a desired bandwidth of communication, but switches into a no-pass mode when encountered with high-power threats. A novel integrated second-order filter-limiter device utilizing a plasma shell is introduced, which consists of two coupled split ring resonators (SRRs), each loaded with a gas discharge tube (GDT), as integrated plasma cells. At low input powers, the device exhibits a bandpass filter behavior whose fractional bandwidth and insertion loss can be controlled by the resonator quality factor, external coupling coefficient to the resonators, and the inter-resonator coupling coefficient. However, when a high-power threat is encountered, plasma forms inside the GDTs, drastically reducing the resonator quality factor by increasing its loss and limiting the signal transferred to the output port. The limiter isolation is proportional to the input power as a higher input power results in more substantial plasma discharges, resulting in higher resonator losses and lower transmitted signals. We implemented a prototype on a PCB using planar SRRs and commercially available GDTs. The fabricated device performed in agreement with the theory and simulations with over 40-dB isolation during the high input power no-pass state and 2-dB insertion loss during the band-pass state with a 3.5% 10-dB FBW.
more extensive Lactiplantibacillus plantarum ZJ316–fermented milk ameliorates dextran sulfate sodium–induced chronic colitis by improving the inflammatory response and regulating intestinal microbiota

The pathogenesis of inflammatory bowel disease may be related to local inflammatory damage and disturbances in intestinal microecology. Probiotic therapy is a safe and effective therapeutic approach. Considering that fermented milk is accepted and enjoyed by many people as a daily dietary intervention strategy, its potential to alleviate dextran sulfate sodium (DSS)– induced chronic colitis in mice needs to be explored. In this study, we evaluated the therapeutic effects of Lactiplantibacillus plantarum ZJ316–fermented milk by establishing a mouse model of DSS-induced chronic colitis. The results showed that the disease severity and colonic lesions of inflammatory bowel disease were effectively alleviated by ingestion of fermented milk. At the same time, the expression of proinflammatory cytokines (TNF-α, IL-1β, and IL-6) effectively decreased, and the expression of antiinflammatory cytokines (IL-10) increased. Results based on 16S rRNA gene sequencing indicated that the structure and diversity of intestinal microorganisms changed markedly by intake of L. plantarum ZJ316–fermented milk, and fermented milk reduced the abundance of harmful bacteria ( Helicobacter ) while promoting the growth of beneficial bacteria ( Faecalibacterium , Lactiplantibacil-lus , and Bifidobacterium ). Additionally, the levels of short-chain fatty acids (acetic acid, propionic acid, butyric acid, pentanoic acid, and isobutyric acid) were also increased. In conclusion, the intake of L. plantarum ZJ316–fermented milk can alleviate chronic colitis by suppressing the inflammatory response and regulating intestinal microbiota.
