Adjustment of phosphorus concentration to increase growth and yield of cherry tomato using hydroponic drip system

The phosphorus element plays an essential role in plant growth both at the vegetative and generative phases, so its concentration modification in the nutrient solution is necessary to stimulate vegetative growth and crop yield. The research aimed to know the influence of different phosphorus concentrations on growth and yield of cherry tomato using a hydroponic drip irrigation system, conducted from February to June 2017 at Green House Research Station of Universitas Padjajaran Jatinangor using Completely Randomized Design with five treatments and five replications. The treatments were: phosphorous concentration of 100 ppm (P/N ratio 0.4), 125 ppm (P/N ratio 0.5), 150 ppm (P/N ratio 0.6), 175 ppm (P/N ratio 0.7), and 200 ppm (P/N ratio 0.8). The results showed that the increasing concentration of phosphorus improved crops height at the end of the vegetative phase, increased the number of flowers from the beginning to the end of the generative period, was able to prevent the flower fall, enhanced harvest index and weight of tomato fruit significantly at harvest time. Application of 200 ppm phosphorus concentration can increase growth and yield of cherry tomato. Unsur fosfor berperan penting dalam pertumbuhan tanaman pada fase vegetatif maupun fase generatif.

Effect of Nutrient Sources on Nutritional Quality of Barley (Hordeum vulgare L.)

Barley is one of the most important crops of the world and is cultivated over almost all parts of the word except tropical region. It was considered to be the first ever cereal crop to be domesticated. It is available in a variety of forms like whole barley, hulled barley, pearled barley as well as barley flakes. Along with Emmer wheat, low yielding owned wheat, barley was a staple food crop of ancient Egypt, dating back to as for as 5000 BC as ever earlier than that. At that time the main use of barley was limited to making beer and bread. It is a rich source of metals like zinc, copper, phosphorus, calcium and iron.
Activation of Epithelial Growth Factor Receptor Pathway by Unsaturated Fatty Acids

Abstract—Nonesterified fatty acids (NEFAs) are acutely liberated during lipolysis and are chronically elevated in pathological conditions, such as insulin resistance, hypertension, and obesity, which are known risk factors for atherosclerosis. The purpose of this study was to investigate the effect and mechanism of action of NEFAs on the epithelial growth factor (EGF) receptor (EGFR). In the ECV-304 endothelial cell line, unsaturated fatty acids triggered a time- and dose-dependent tyrosine phosphorylation of EGFR (polyunsaturated fatty acids [PUFAs] were the most active), whereas saturated FAs were inactive. Although less potent than PUFAs, oleic acid (OA) was used because it is prominent in the South European diet and is only slightly oxidizable (thus excluding oxidation derivatives). EGFR is activated by OA independent of any autocrine secretion of EGF or other related mediators. OA-induced EGFR autophosphorylation triggered EGFR signaling pathway activation (as assessed through coimmunoprecipitation o.
Resistance Test of Some Bacterial Synthetic Calcular Cycinaris Invitro Amoxicillin and Ciprofloxacin Antibiotics in TK II Pelamonia Hospital Makassar, Indonesia

Sinusitis is defined as mucosal inflammation of the paranasal sinuses. Generally triggered by rhinitis so called rhinosinusitis. The main cause is sales (commond cold) which is a viral infection, which is then followed by bacterial infection. The main treatment most often used for chronic maxillary sinusitis is antibiotics, and therefore tested for resistance of antibiotics amoxicillin and ciprofloxacin. The method used in the research is the Kirby Bauer method by using a disk that contains antibiotic concentration. The sample used is a chronic maxillary sinusitis fluid taken from 12 patients who were positive for chronic maxillary sinusitis. From the results of bacterial isolation, all patients infected with Staphylococcus aureus, 7 patients infected with the bacteria Streptococcus pneumoniae and 2 patients infected with Haemophilus influenzae were found. The test results showed that all bacteria were resistant to the antibiotic amoxicillin and sensitive to the antibiotic ciprofloxacin.
Analyzing the influence of user-generated-content (UGC) on social media platforms in travel planning

In recent years Social Media (SM) platforms are becoming highly significant for the tourism industry as a medium for information exchange and communication platforms for tourists and travelers. Tourists are using Web 2.0 platforms to plan their travel, book hotels, confirm and cancel reservations, enquire about packages and itineraries, to read reviews posted by other travelers, and also to share their travel experiences by posting reviews, comments, ratings, photographs, etc. with others. The purpose of this study is to determine the influence of user-generated-contents on social media platforms in the travel planning of tourists in Udaipur, India. This study analyze the opinion of tourists regarding the benefits of social media and travel material posted on various social media platforms and to draw factors that are helpful in influencing the use of information through social media. To fulfill the objectives, primary data was collected by using a judgmental sampling method and a 5-point Likert type scale through a structured questionnaire. A sample of 309 respondents who visited Udaipur as a tourist during the period of early October 2017 to the end of March 2018 was surveyed. Using descriptive statistics and factor analysis results were presented and explained. The findings revealed that tourists have a positive opinion towards online reviews and travel material posted on social sites. The majority of the tourist respondents opined that online reviews, ratings, and comments, etc. regarding travel destinations, hotels, food, and climate, etc. help in their travel planning and travel related decisions. The results of factor analyses demonstrated that three factors namely; social media ease and trust, social media risk reduction and helpfulness and social media enhance joy and excitement were considered helpful in influencing the use of information through social media sites.
The roles of temperature and host plant interactions in larval development and population ecology of Parnassius smintheus Doubleday, the Rocky Mountain Apollo butterfly

Alpine environments are harsh and unpredictable. Exogenous factors such as weather might therefore be expected to dominate processes affecting population dynamics of alpine organisms, relative to endogenous factors including plant-animal interactions. The alpine butterfly Parnassius smintheus Doubleday is a specialist on Sedum lanceolatum. I examine the importance of interactions between P. smintheus larvae and S. lanceolatum, specifically the potential for an induced defense, indicating that host plant/herbivore interactions may play a significant role in P. smintheus populations. I also examine the effect of temperature (as a component of climate) on the development and survival of P. smintheus caterpillars. Using laboratory and field studies I show that host plant interactions are not important for P. smintheus in the field, and instead moderate changes in temperature are more likely to affect P. smintheus populations. I suggest that any population-level effects of temperature will likely be indirect and mediated through phenological shifts.
Towards an Assessment of Pause Periods on User Habituation in Towards an Assessment of Pause Periods on User Habituation in Mitigation of Phishing Attacks Mitigation of Phishing Attacks

Abstract Social engineering is the technique in which the attacker sends messages to build a relationship with the victim and convinces the victim to take some actions that lead to significant damages and losses. Industry and law enforcement reports indicate that social engineering incidents costs organizations billions of dollars. Phishing is the most pervasive social engineering attack. While email filtering and warning messages have been implemented for over three decades, organizations are constantly falling for phishing attacks. Prior research indicated that attackers use phishing emails to create an urgency and fear response in their victims causing them to use quick heuristics, which leads to human errors. Humans use two types of decision-making processes: a heuristic decision, which is a quick, instinctual decision-making process known as ‘System One’, and a second, known as ‘System Two,’ that is a slow, logical process requiring attention. ‘System Two’ is often triggered by a pause in the decision-making process. Additionally, timers were found in other research fields (medicine, transportation, etc.) to affect users’ judgement and reduce human errors. Therefore, the main goal of this work-in-progress research study is to determine through experimental field study whether requiring email users to pause by displaying a phishing email warning with a timer, has any effect on users falling to simulated phishing attacks. This paper will outline the rationale and the process proposed for the validation of the field experiments with Subject Matter Experts (SMEs). Limitations of the proposed study and recommendation for further research are provided.
Climate sensitivities and uncertainties in food‐web pathways supporting larval bluefin tuna in subtropical oligotrophic oceans

&NA; Compared with high‐latitude seas, the ecological implications of climate change for top consumers in subtropical regions are poorly understood. One critical area of knowledge deficiency is the nature of food‐web connections to larvae during their vulnerable time in the plankton. Bluefin tuna (BFT) are highly migratory temperate species whose early life stages are spent in ultra‐oligotrophic subtropical waters. Dietary studies of BFT larvae provide evidence of prey‐limited growth coupled with strong selection for specific prey types—cladocerans and poecilostomatoid copepods—whose paradoxical or poorly resolved trophic characteristics do not fit the conventional understanding of open‐ocean food‐web structure and flows. Current knowledge consequently leaves many uncertainties in climate change effects, including the possibility that increased nitrogen fixation by Trichodesmium spp. might enhance resiliency of BFT larvae, despite a projected overall decline in system productivity. To advance understanding and future predictions, the complementary perspectives of oceanographers and fisheries researchers need to come together in studies that focus on the trophic pathways most relevant to fish larvae, the factors that drive variability in spawning regions, and their effects on larval feeding, growth, and survival.
Anthropometry based Predictive Equations for Estimating Nigerian Women Percentage Body Fat using Stable Isotope Technique as Reference

The direct measurement of body composition using innovative non-or minimally-invasive technologies such as stable isotope technique, despite its reliability and precision remains a significant challenge. Â This study was designed to develop predictive equations for estimating the percentage body fat of Nigerian women using isotope dilution (ISD) or gold standard technique (as in IAEA procedure) as reference and validated by bioelectrical impedance technique.The percentage body fats (% BF) of 173 Nigerian women (aged 18-55 yrs) were estimated using isotope dilution (ISD) or gold standard technique (as in IAEA procedure) as reference and validated by bioelectrical impedance technique. The skinfold thicknesses (mm) such as biceps, triceps, subscapular, suprailiac and abdominal were measured using skinfold langre callipers while body circumferences such as forearm, wrist, waist, abdominal and hip were measured using standard tape rule and in accordance with WHO guidelines. Â The subjectsâ€™ percentage body fat (%BF) ranged from 8.0 to 48.5. Generally, at 0.01 level of significance (Using Statistical Package for Social Scientists (SPSS), higher positive significant correlations were obtained between % BF by ISD and body circumferences (r=0.503-0.874) than skinfold thicknesses (r=0.503-0.739). Using forward selection regression procedure, three sex-specific based predictive equations for estimating %BF (incorporating subjectsâ€™ weight and body circumferences such as hip, abdominal and waist) were developed based on the subjectsâ€™ ethnic groups (Yoruba, Hausa and Ibos) with high R2 (0.853, 0.953 & 0.867) and low Pure errors (3.316, 2.791 & 2.324) respect. These equations provide easy way of measuring percentage body fat and are recommended for use in clinical or epidemiological settings in populations with similar ethnic background and in lieu of isotope dilution method.
Predicting consumers’ intention to consume poultry during an H7N9 emergency: an extension of the theory of planned behavior model

Abstract Based on the theory of planned behavior (TPB), this article explains the impact of H7N9 on poultry meat consumption. A sample of 710 respondents from China participated in the current study following an outbreak of avian influenza in 2017. The empirical results of structural equation model indicate that the consumers’ attitude, subjective norm, perceived behavioral control (i.e., the antecedents of the TPB model), as well as their anticipated fear, mediate the relationship between risk perception of H7N9 and poultry consumption intention. Risk perception of H7N9 also influences risk perception of poultry, which has a direct effect on poultry consumption intention. Furthermore, risk perception of poultry is significantly and positively related to anticipated fear and is significantly and negatively related to attitude, which in turn influences the consumption intention. The results confirm the appropriateness of the TPB model and verify that the extended TPB model has good explanatory power in predicting consumers’ intention to consume poultry during a pandemic.
Conservation implications of habituation in Nubian ibex in response to ecotourism

Increased fragmentation and easier access to natural areas (e.g. ecotourism) is bringing man in closer contact to wild populations. Such encounters, even when they don't pose a direct threat to wildlife, may induce behavioral changes in animals that in the long run may have negative fitness consequences. We studied changes to the vigilance/group‐size effect in Nubian ibex Capra nubiana in response to increased non‐threatening anthropogenic disturbance in six sites, subject to different levels of ecotourism. In each site we regressed the average time ibex individuals devoted to vigilance on the size of the group they were with. We then compared the slopes and intercepts of the vigilance/group‐size function between the six sites. We complimented these data with a study of how flight initiation distance (FID) changed between the six sites, as an indicator of the level of tolerance that ibex exhibit to increased anthropogenic presence. We found that as anthropogenic presence increased the vigilance/group‐size function waned (i.e. the group‐size effect was weaker). These findings were associated with reduced FID reflecting increased levels of tolerance, likely as a result of habituation in sites subject to high levels of ecotourism. The loss of the vigilance response as a function of group size may decrease the behavioral diversity in the ibex population. Wildlife habituation to increased non‐threatening human activity alters key behavioral attributes that may ultimately impact social structure and other fitness‐related characteristics.
Gender-Typed Sport Practice, Physical Self-Perceptions, and Performance-Related Emotions in Adolescent Girls

Youth sport experience provides opportunities for physical, personal, and social development in youngsters. Sport is a social system in which socially constructed gender differences and stereotypes are incorporated, and specific sport activities are often perceived as gender characterized. The objective of this study was to examine the relationship between some salient physical and emotional self-perceptions and the type of sport practiced. A sample of 261 female athletes, aged 14–21 years (Mage = 15.59, SD = 2.00), practicing different sports, categorized as feminine (e.g., artistic and rhythmic gymnastics), masculine (e.g., soccer and rugby), or neutral (e.g., track and field and tennis), took part in a cross-sectional study. Significant differences were observed between aesthetic sports and other types of sports. Athletes involved in aesthetic sports reported the lowest values in their feelings of confidence and the highest values in feelings of worry related to competition. This may be attributed to the evaluation system of aesthetic sports, in which the athlete’s performance is evaluated by a jury. At the same time, they reported low values of dysfunctional psychobiosocial states associated with their general sport experience, likely because of their physical appearance close to the current body social standards for girls. Notwithstanding the differences by type of sport, athletes of all disciplines reported high mean values of functional psychobiosocial states, suggesting that their overall sporting experience was good.
Reaching Performance in Heathy Individuals and Stroke Survivors Improves after Practice with Vibrotactile State Feedback

REACHING PERFORMANCE IN HEALTHY INDIVIDUALS AND STROKE SURVIVORS IMPROVES AFTER PRACTICE WITH VIBROTACTILE STATE FEEDBACK Valay A. Shah, B.S. Marquette University, 2020 Stroke causes deficits of cognition, motor, and/or somatosensory functions. These deficits degrade the capability to perform activities of daily living (ADLs). Many research investigations have focused on mitigating the motor deficits of stroke through motor rehabilitation. However, somatosensory deficits are common and may contribute importantly to impairments in the control of functional arm movement. This dissertation advances the goal of promoting functional motor recovery after stroke by investigating the use of a vibrotactile feedback (VTF) body-machine interface (BMI). The VTF BMI is intended to improve control of the contralesional arm of stroke survivors by delivering supplemental limb-state feedback to the ipsilesional arm, where somatosensory feedback remains intact. To develop and utilize a VTF BMI, we first investigated how vibrotactile stimuli delivered on the arm are perceived and discriminated. We determined that stimuli are better perceived sequentially than those delivered simultaneously. Such stimuli can propagate up to 8 cm from the delivery site, so future applications should consider adequate spacing between stimulation sites. We applied these findings to create a multichannel VTF interface to guide the arm in the absence of vision. In healthy people, we found that short-term practice, less than 2.5 hrs, allows for small improvements in the accuracy of horizontal planar reaching. Long-term practice, about 10 hrs, engages motor learning such that the accuracy and efficiency of reaching is improved and cognitive loading of VTF-guided reaching is reduced. During practice, participants adopted a movement strategy whereby BMI feedback changed in just one channel at a time. From this observation, we sought to develop a practice paradigm that might improve stroke survivors’ learning of VTF-guided reaching without vision. We investigated the effects of practice methods (whole practice vs part practice) in stroke survivors’ capability to make VTF-guided arm movements. Stroke survivors were able to improve the accuracy of VTF-guided reaching with practice, however there was no inherent differences between practice methods. In conclusion, practice on VTF-guided 2D reaching can be used by healthy people and stroke survivors. Future studies should investigate long-term practice in stroke survivors and their capability to use VTF BMIs to improve performance of unconstrained actions, including ADLs.
New analytical solutions of heat transfer flow of clay-water base nanoparticles with the application of novel hybrid fractional derivative

Clay nanoparticles are hanging in three different based fluids (water, kerosene, and engine oil). The exact terminologies of Maxwell-Garnett and Brinkman for the current thermophysical properties of clay nanofluids are used, while the flow occurrence is directed by a set linear PDE with physical initial and boundary conditions. The classical governing equations are extended to non-integer order hybrid fractional derivative which is introduced in [33]. Analytical solutions for temperature and ve? locity fields are attained via Laplace transform technique. Some limiting solutions are also obtained from the existing literature and compared for different values of fractional parameter. To vision the impact of several flow parameters on the temperature and velocity some graphs are drawn using Mathcad software and designed in different figures. As a result, we found that hybrid fractional model is better in describing the decay behavior of temperature and velocity in comparison of classical derivatives. In comparison of nanofluid with different base fluids, it is concluded that water-based nanofluid has higher velocity than others.
Vertical habitat utilization by tagged yellowfin tuna (Thunnus albacares) released in the Revillagigedo Archipelago Biosphere Reserve, Mexico

A description of vertical habitat use by yellowfin tuna, Thunnus albacares, captured and released with archival tags in the Revillagigedo Archipelago Biosphere Reserve, Mexico, during the 2006–2011 period is given. An analysis was made of internal and ambient temperatures, depth, and time of day registered in 68 archival tags recovered from tuna caught mostly in sets associated with dolphins by Mexican purse-seine vessels. Tuna were classified into 3 age groups (I, II, and III) for analyses. Vertical movements were analyzed by dividing the water column into 10 depth strata. The 3 age groups remained the longest in the uppermost stratum (0–25 m), and their presence began to diminish in subsequent strata, with some occasional visits at >500-m depths. In the >500 m stratum, age group III was the one with the longest time investment with 45 min on average. Presence at different depths throughout the day showed significant differences among age groups (Wald’s test expressed as χ2, P < 0.05). The physiological adaptation of yellowfin tuna to maintain minimal changes in its internal temperature at different depths gives it the advantage to expand its food search to deep zones where temperature oscillates around 5 ºC.
