Abstract

This research is motivated because it found students' difficulties when experimenting to determine the magnitude of restitution coefficient. First, the determination of the initial height, the height of the second reflection and so on is not appropriate because it must observe something in a very short time. Second, the initial high determination is too high. Third, the object is oversize. Allegedly, existing worksheets do not facilitate students to experiment properly. This study aims to improve the experimental worksheet and redesign the experimental tool, so students will more easily understand how to experiment properly. This research is a classroom action research. Students' experimental abilities were obtained by comparing the answers of student worksheets before reconstruction and student answers after reconstruction. The results show that reconstructed worksheets can improve students' ability to experiment.

Keywords: Redesigning the appartures, Worksheets, Restitution Coefficients, Experimenting Skills.

Biosolids Promote Similar Plant Growth and Quality Responses as Conventional and Slow-release Fertilizers
Authors: Broderick Shaun R. , Evans Williams B.
Published: December 2017

Biosolids are rich in plant nutrients and are a byproduct of municipal wastewater treatment and those that meet strict government safety standards can be land applied in most agricultural settings except for the U.S. Department of Agriculture (USDA) certified organic production. Across the United States, about 60% of biosolids are land applied, but in Mississippi almost no biosolids are land applied. Our research goal was to compare plant size in southeastern U.S. soils amended with biosolids at rates of 2, 8, 14, and 20 tons/acre in contrast to soils amended with synthetic fertilizers using ‘Floral Lace Cherry’ dianthus (Dianthus chinensis ×barbatus), ‘Dreams Coral Morn’ petunia (Petunia ×hybrida), ‘Pidgeon White’ kale (Brassica oleraceae var. acephala), and ‘Bright Lights’ swiss chard (Beta vulgaris ssp. cicla). To accomplish this, fertilizers and biosolids were applied to prebedded fields in a randomized complete block design with a split-plot arrangement of nutrient treatments. Plant performance data and soil data were taken 43 and 56 days after transplant. Soil pH was reduced and organic matter increased at the highest application rates (14 and 20 tons/acre) of biosolids, and higher levels of phosphorus, zinc, and sulfur were found in these soils. In plant shoots, higher levels of copper, manganese, magnesium, and zinc were found when grown in soils amended with biosolids at a rate of 20 tons/acre compared with plants grown with synthetic fertilizers. Except for swiss chard, no crops fertilized with biosolids exhibited a difference in dry weights (DW) compared with conventional fertilizers. These data demonstrate that soil properties can be improved and similar plant sizes can be achieved through biosolid applications. We conclude that Grade A biosolids produced in Mississippi can be used to supplement synthetic fertilizers for ornamental and vegetable production.

Extension and research professionals in the southeastern United States formed the Southern Nursery Integrated Pest Management working group (SNIPM) to foster collaboration and leverage resources, thereby enhancing extension programming, increasing opportunity, and expanding the delivery of specialized expertise to nursery crop growers across a region. Building a productive and lasting working group requires attracting a group of research and extension faculty with complementary expertise, listening to stakeholders, and translating stakeholder needs into grant priorities to help solve problems, all hallmarks of effective teamwork principles. SNIPM has now grown to include 10 U.S. states and 11 institutions and has been awarded seven grants totaling $190,994 since 2009. A striking benefit of working group membership was observed over time: synergy. Greater awareness of individual expertise among SNIPM members, each of whom were focused on different aspects of the nursery production system stimulated multistate extension publications, electronic books (eBooks), mobile device applications (apps), popular press articles, and spin-off research projects when separate foci were combined and directed toward complex challenges. Deliverables achieved from this faculty collaboration include nine peer-reviewed publications, four manuals and books and 23 book chapters, and a combined total of 11 abstracts, conference proceedings and extension publications. To date, the return on investment for SNIPM is one deliverable produced to every $2265.89 in grant funding. SNIPM has also been honored with multiple American Society for Horticultural Science publication awards as well as the Southern Region Integrated Pest Management Center Bright Idea Award for the quality and originality of their project outputs. Continuing to work together toward common goals that bridge technology and serve the nursery industry while supporting each individual member’s program will be crucial to the long-term success of this working group.

Three, 2-day hands-on experiential learning workshops were presented in three southeastern United States cities in June 2014, by the Southern Nursery Integrated Pest Management (SNIPM) working group. Attendees were provided 4 hours of instruction including hands-on demonstrations in horticultural management, arthropods, plant diseases, and weeds. Participants completed initial surveys for gains in knowledge, skills, and abilities as well as their intentions to adopt various integrated pest management (IPM) practices after the workshop. After 3 years, participants were again surveyed to determine practice adoption. Respondents changed their IPM practice behavior because of attending the workshops. Those returning the survey set aside more time to scout deliberately for pests, plant diseases, and weeds; used a standardized sampling plan when scouting; and adopted more sanitation practices to prevent plant disease. Fewer horticultural management practices were adopted than respondents originally intended. Future emphasis should be placed on using monitoring techniques to estimate pest emergence, for example, traps and pheromone lures, as well as plant phenology and record keeping. However, more work is needed to highlight both the immediate and long-term economic benefits of IPM practice adoption in southeastern U.S. nursery production.
A Novel Biomechanical Analysis of Horticultural Digging
Authors: Shippen James , Alexander Paul , May Barbara
Published: December 2017

Musculoskeletal injuries are commonly reported in workers employed in labor-intensive agricultural-type tasks. A novel method of determining joint angles, joint torques, and contact forces, using three-dimensional motion capture and musculoskeletal modeling, was applied to the movements of a sample of workers, engaged in the horticultural task of digging, to determine if objective biomechanical data could be correlated with a subjective visual assessment to predict risk of injury. The joint angle time histories of horticulturists were calculated from the motion capture data, and this was used to articulate a musculoskeletal model of the subjects. The joint torques were calculated using inverse dynamics methods from which the individual muscle loads were established using a cost function minimization approach. Finally, the joint contact forces were calculated including the muscle forces. The motion capture data of digging trials were observed by a team of horticulturists and physiotherapists who categorized each of the observed trials according to form, efficiency, and risk of injury. Trials demonstrating techniques which were more likely to yield injuries were identified as “examples of bad technique”; those judged to be less likely to yield injuries were categorized as “examples of good technique.” It was found that the joint torques and contact forces and their variability were lower in the trial which was identified as good technique, and consistently higher in the examples of bad technique. The results of the study suggest that measurement of joint angles, joint torques, joint contact forces, and forces in the muscles could serve as a valuable tool to develop training programs for horticultural workers engaged in certain high intensity tasks, such as digging, to effectively improve efficiency and reduce incidence of injury. It may also be possible to modify horticulture-related equipment to minimize the internal loads within the body to reduce the risk to health and, therefore, extend active participation in horticulture.

Published: December 2017

Studies were conducted in North Carolina to determine the effect of holding durations (HDs) [0, 1, 3, 5, and 7 days before planting (DBP)] of ‘Covington’ sweetpotato (Ipomoea batatas) transplants on plant stand and storage root numbers and yield in production fields. In a second field study, the effect of preplant irrigation (PI) treatments (PI and nonirrigation) were evaluated along with the transplant HD on plant stand, storage root numbers, and yield. Transplants held for 7 DBP did not survive as well as the other treatments (lower plant stands) and had lower no. 1, marketable, and total storage root numbers and yields than other holding treatments. HD of 1 or 3 DBP resulted in higher plant stands, and no. 1, marketable, and total numbers of storage roots and yields than holding for 0, 5, or 7 DBP. This study affirms the importance of soil moisture at and shortly after planting for transplant survival and yield. Holding transplants for 1–3 DBP can improve stand establishment and yields when dry conditions occur either before or soon after planting. However, holding transplants for 7 DBP can result in reduced plant stands and yields when stress/dry conditions occur soon after planting.

Published: December 2017

Grafting is considered to be a unique component in sustainable vegetable production. In addition to its usefulness for managing soil-borne diseases, it has been suggested that grafting with vigorous rootstocks can improve crop growth and yield. The objective of this greenhouse study was to assess the effects of different interspecific hybrid tomato rootstocks (Solanum lycopersicum × Solanum habrochaites) on yield, growth, nutrient accumulation, and fruit composition of tomato (S. lycopersicum). Using the determinate tomato cultivar Florida 47 as the scion, plants were grafted onto four interspecific rootstock cultivars including Beaufort, Maxifort, Multifort, and RST-04-105. Overall, the use of rootstocks resulted in total and marketable fruit increase 53% and 66% higher than non-grafted and self-grafted scion plants, respectively. The increase in marketable yield by ‘Beaufort’, ‘Maxifort’, and ‘Multifort’ was largely attributed to an increased number of fruit per plant, whereas higher average fruit weight contributed to the yield increase in plants grafted onto ‘RST-04-105’. Self-grafting of ‘Florida 47’ resulted in similar yield as the non-grafted scion control. Analyses of plant growth parameters demonstrated significant enhancement of total leaf area at first fruit harvest in plants grafted onto interspecific rootstocks as compared with the non-grafted and self-grafted scion controls. In addition to plant growth and yield improvement, enhanced accumulation of nitrogen, potassium, and calcium was also observed in grafted plants. The enhancement in mineral nutrient accumulation was largely related to increased biomass accumulation rather than higher nutrient concentration (on a dry weight basis). The overall accumulation of phosphorus was not influenced markedly by the rootstocks used. In general, grafting with the interspecific rootstocks maintained fruit soluble solids content (SSC) and total titratable acidity (TTA), concentrations of vitamin C, carotenoids, and total phenolics at levels comparable with non-grafted plants, whereas harvest date showed a more pronounced effect on fruit composition.

Published: December 2017

Favorable agro-climatic conditions and comparatively cheaper and readily available human resources offer a promising business opportunity to cut flower production in Pakistan. Presently, growers are limited to traditional cut flower crops such as rose (Rosa hybrids), gladiolus (Gladiolus hybrids), marigold (Tagetes erecta), and tuberose (Polianthes tuberosa) because of unavailability of improved new species and cultivars. To diversify cut flower production in Pakistan, a study was conducted to evaluate the production and postharvest performance of different cultivars of delphinium (Delphinium hybrids), snapdragon (Antirrhinum majus), and stock (Matthiola incana) in Faisalabad, Punjab, Pakistan. ‘Guardian White’ delphinium had the shortest time to harvest first marketable stems (160 days) with comparatively shorter stems (87.7 cm). Whereas ‘Aurora White’ and ‘Aurora Blue’ were high-temperature tolerant and produced attractive racemes with longer stems; 112.0 and 99.7 cm, respectively. All cultivars lasted about 7 days in distilled water (DW). ‘Cheerful White’ stock had the shortest cropping time and produced highest quality double flowers with longest stems (51.8 cm) compared with other cultivars tested. Vase solution of 4% sucrose supplemented with 100 mg·L−1 silver nitrate (AgNO3) extended the vase life of ‘Cheerful White’ stock up to 11.8 days compared with 8.2 days in DW. Pulsing with 10% sucrose supplemented with 100 mg·L−1 AgNO3 extended the longevity of ‘Lucinda Dark Rose Double’ stock (10.2 days) similar to vase solution of 4% sucrose plus 100 mg·L−1 AgNO3; however, ‘Lucinda Dark Rose Double’ stock produced shorter stems than ‘Cheerful White’. ‘Appleblossom’ snapdragon produced >10 marketable stems per plant with highest quality attractive flowers, and stout stems, which lasted 10.8 days in 4% sucrose vase solution supplemented with 100 mg·L−1 AgNO3. Among tested species/cultivars, all exotic species/cultivars produced uniform high quality stems resulting in higher productivity as compared with local cultivars and were favorably appraised by flower growers/retailers and are best suited for diversification of local cut flower industry.
Impact Indicators for Community Garden Programs: Using Delphi Methods to Inform Program Development and Evaluation
Authors: Diaz John , Webb Susan , Warner Laura , Monoghan Paul
Published: December 2017

With growing interest in food system solutions to address poor health outcomes related to preventable chronic diseases, organizations and researchers are examining the value of community gardens as interventions to promote individual and community health. Research suggests that participation in community gardens improves access to fresh, healthy foods and increases fruit and vegetable consumption. In addition to these physical benefits, research also documents a variety of social and communal benefits, by expanding social capital, stabilizing neighborhoods, and cultivating relationships. Unfortunately, most of these studies focus on a specific case, cross case, or intervention studies within a geographically specific locale. Learning lessons from successful community garden programs can be difficult because community gardens often rely on the synergy of a complex network of support agencies that assist in various technical and educational capacities. The purpose of the study was to demonstrate the use of a framework for program development and evaluation that stakeholders, including extension, can adopt to show program outcomes. The framework used a Delphi approach with a diverse panel of community garden stakeholders to reach consensus about program outcomes. The study demonstrated that the panel could reach consensus on a variety of short-, medium-, and long-term outcomes.
Application of the methodology for determining the “growth poles” of the region’s industrial economy in the system of public administration
Authors: Pysar Nadiia
Published: December 2017

The article deals with the topical issue of applying the theory of “growth poles” to the economic development of Ukraine. A variety of theoretical definitions of the “growth pole” concept existing in the world economic and scientific thought has been studied. The ways and issues of practical application of the theory of “growth poles” for the Ukrainian economy have been identified. It has been proved that the formation of “growth poles” in industry is the determination of priority locomotive branches of the region’s industrial economy. The possible mechanisms of their localization in the form of growth areas have been substantiated. The methodology for determining “growth areas” of the industrial region has been developed and applied to the industry of the Carpathian economic region. In order to identify regional economic growth areas, Ivano-Frankivsk, Lviv, Chernivtsi, and Zakarpattia regions have been analyzed, evaluated, and classified for the period 2011–2016: by the relative share of the industry in the total output produced in the region of interest; by the relative share of unprofitable businesses in the industry; by the level of profitability of industries (goods) and by the monetary value of the profit earned by industries. The procedure for classifying the branches has been put forward for the purpose of identifying economic growth areas by totality of leading businesses and by fiscal performance (size of tax payments) of industries. It has been proved that the advanced development of the region’s industrial economy is possible as a result of intensifying the areas of the growth poles, with the priority innovative and investment projects for the development of the locomotive regional branches serving as the principal growth areas of the regional economy.
A Systematic Review of Evidence-based Treatment Strategies for Obsessive- compulsive Disorder Resistant to first-line Pharmacotherapy
Authors: Albert Umberto , Marazziti Donatella , Di Salvo Gabriele , Solia Francesca , Rosso Gianluca , Maina Giuseppe
Published: December 2017

Background:

Serotonin reuptake inhibitors (SRIs) and cognitive-behavioral psychotherapy
(CBT) are first-line treatments for obsessive-compulsive disorder (OCD). However,
a significant proportion of patients do not respond satisfactorily to first-choice treatments.
Several options have been investigated for the management of resistant patients.

Objective:

The aim of the present paper is to systematically review the available literature
concerning the strategies for the treatment of resistant adult patients with OCD.

Method:

We first reviewed studies concerning the definition of treatment-resistant OCD;
we then analyzed results of studies evaluating several different strategies in resistant patients.
We limited our review to double-blind, placebo-controlled studies performed in
adult patients with OCD whose resistance to a first adequate (in terms of duration and
dosage) SRI trial was documented and where outcome was clearly defined in terms of decrease
in Yale-Brown Obsessive-Compulsive Scale (YBOCS) scores and/or response/
remission rates (according to the YBOCS).

Results:

We identified five strategies supported by positive results in placebo-controlled
randomized studies: 1) antipsychotic addition to SRIs (16 RCTs, of them 10 positive; 4
head-to-head RCTs); among antipsychotics, available RCTs examined the addition of
haloperidol (butyrophenone), pimozide (diphenyl-butylpiperidine), risperidone (SDA: serotonin-
dopamine antagonist), paliperidone (SDA), olanzapine (MARTA: multi-acting
receptor targeted antipsychotic), quetiapine (MARTA) and aripiprazole (partial dopamine
agonist); 2) CBT addition to medication (2 positive RCTs); 3) switch to intravenous
clomipramine (SRI) administration (2 positive RCTs); 4) switch to paroxetine (SSRI: selective
serotonin reuptake inhibitor) or venlafaxine (SNRI: serotonin-norepinephrine reuptake
inhibitor) when the first trial was negative (1 positive RCT); and 5) the addition of
medications other than an antipsychotic to SRIs (18 RCTs performed with several different
compounds, with only 4 positive studies).

Conclusion:

Treatment-resistant OCD remains a significant challenge to psychiatrists. To
date, the most effective strategy is the addition of antipsychotics (aripiprazole and risperidone)
to SRIs; another effective strategy is CBT addition to medications. Other strategies,
such as the switch to another first-line treatment or the switch to intravenous administration
are promising but need further confirmation in double-blind studies. The addition of
medications other than antipsychotics remains to be studied, as several negative studies
exist and positive ones need confirmation (only 1 positive study).
Identification of the Multifaceted Chemopreventive Activity of Curcumin Against the Carcinogenic Potential of the Food Additive, KBrO3
Authors: Obaidi Ismael , Higgins Michael , Bahar Bojlul , Davis Jessica L. , McMorrow Tara
Published: December 2017

Background:

Potassium bromate (KBrO3), a food additive, has been used in many bakery products as
an oxidizing agent. It has been shown to induce renal cancer in many in-vitro and in-vivo experimental models.

Objectives:

This study evaluated the carcinogenic potential of potassium bromate (KBrO3) and the chemopreventive
mechanisms of the anti-oxidant and anti-inflammatory phytochemical, curcumin against KBrO3-induced
carcinogenicity.

Method:

Lactate dehydrogenase (LDH) cytotoxicity assay and morphological characteristics were used to assess
curcumin's cytoprotective potential against KBrO3 toxicity. To assess the chemopreventive potential of curcumin
against KBrO3-induced oxidative insult, intracellular H2O2 and the nuclear concentration of the DNA adduct 8-
OHdG were measured. PCR array, qRT-PCR, and western blot analysis were used to identify dysregulated genes
by KBrO3 exposure. Furthermore, immunofluorescence was used to evaluate the ciliary loss and the disturbance
of cellular tight junction induced by KBrO3.

Results:

Oxidative stress assays showed that KBrO3 increased the levels of intracellular H2O2 and the DNA adduct
8-OHdG. Combination of curcumin with KBrO3 efficiently reduced the level of H2O2 and 8-OHdG while upregulating
the expression of catalase. PCR array, qRT-PCR, and western blot analysis revealed that KBrO3 dysregulated
multiple genes involved in inflammation, proliferation, and apoptosis, namely CTGF, IL-1, and
TRAF3. Moreover, qRT-PCR and immunofluorescence studies showed that KBrO3 negatively affected the tight
junctional protein (ZO-1) and induced a degeneration of primary ciliary proteins. The negative impact of KBrO3
on cilia was markedly repressed by curcumin.

Conclusion:

Curcumin could potentially be used as a protective agent against carcinogenicity of KBrO3.

Authors: Rasane Prasad , Jha Alok , Kaur Sawinder , Kumar Vikas , Sharma Nitya
Published: December 2017

Background:

A nutricereal based fermented baby food was investigated to predict its shelf
life using chemical kinetic modeling. An optimized baby food formulation, packaged in metalized
polyester packets was stored at accelerated conditions for 180 days and analyzed for Hydroxy Methyl
Furfural (HMF), Thiobarbituric Value (TBA), Free Fatty Acid Content (FFA) and sensory characteristics.

Objective:

The objective of the study was to determine the shelf life of the optimized nutricereal based
fermented baby food using chemical kinetic modeling.

Methods:

Chemical kinetics analysis by investigating the Hydroxymethyl Furfural content, thiobarbituric
value (TBA), free fatty acid content (FFA) and sensory characteristics of the optimized baby food.

Results:

Shelf life model based on chemical and sensory acceptability was derived using Arrhenius
equation modeling. Thus, the baby food had a predictive shelf life of 54 weeks when stored at 10°C in
metalized polyester based on the chemical (HMF, TBA and FFA) and sensory (overall acceptability)
characteristics. A most suitable model based on FFA was developed considering lowest root mean
square (RMS) percentages and least deviations in actual and predicted values.

Conclusion:

Chemcial kinetics could be applied to determine the shelf life of the fermented baby
foods. HMF, TBA and FFA play key role in the shelf life of the stored fermented product. A model
based on FFA is most suitable to determine the shelf life of the powdered nutricereal based fermented
baby food packged in metalized polyster, stored at 10°C.

Published: December 2017

Objectives:

To evaluate the epidemiological patterns of third molar impaction in a cohort of patients living in the north of Saudi Arabia.

Materials and Methods:

A retrospective cohort study comprised of analysing 2550 Orthopantomograms (OPGs) belonging to patients who attended Aljouf University College of Dentistry between September 2013 and December 2015. OPGs were examined to determine the frequency of third molar impaction, their levels of eruption and angulations. Mixed effects logistic regression analysis was performed to calculate adjusted odds ratios. Data were weighted by age and sex based on population regional estimates.

Results:

1551 patients (60.8%) with a mean age of 33.5 years-old (95%CI: 32.9 to 34) demonstrated 2650 impacted third molars. Third molars were more likely present in patients aged from 20 to 39 years-old (p<0.001); and in mandible more than maxilla (p<0.001). It showed highest vertical impaction and higher impaction rate in mandible than maxilla. Level A impaction was the most common among other levels by 1365 (53.5%). Vertical impaction was the most common pattern (1354 patients; 53.1%). Mesioangular impaction ranked second in mandible, while distoangular impaction ranked second in maxilla. There was no statistically significant difference between males and females concerning impaction frequency, depth levels and angulations.

Conclusion:

Impacted third molars is still a public health concern among youth and young adults. Vertically impacted mandibular third molars with their occlusal plane at the same level as the occlusal plane of adjacent tooth is the most prevalent pattern of third molar impaction in the northern region of Saudi Arabia.
A Review Over Benefits and Drawbacks of Combining Sodium Hypochlorite with Other Endodontic Materials
Authors: Mohammadi Zahed , Shalavi Sousan , Moeintaghavi Amir , Jafarzadeh Hamid
Published: December 2017

Introduction:

As the root canal system considered to be complex and unpredictable, using root canal irrigants and medicaments are essential in order to enhance the disinfection of the canal. Sodium hypochlorite is the most common irrigant in endodontics. Despite its excellent antimicrobial activity and tissue solubility, sodium hypochlorite lacks some important properties such as substantivity and smear layer removing ability.

Objective:

The aim of this review was to address benefits and drawbacks of combining sodium hypochlorite with other root canal irrigants and medicaments.

Discussion:

According to the reviewed articles, NaOCl is the most common irrigation solution in endodontics. However, it has some drawbacks such as inability to remove smear layer. One of the drawbacks of NaOCl is its inability to remove the smear layer and lack of substantivity.

Conclusion:

The adjunctive use of other materials has been suggested to improve NaOCl efficacy. Nevertheless, further studies are required in this field.
Bilateral Elongated Mandibular Coronoid Process and Restricted Mouth Opening: A Case Report
Authors: Starch-Jensen Thomas , Kjellerup Annette Dalgaard
Published: December 2017

Introduction:

Mandibular coronoid process hyperplasia is an uncommon congenital or developmental temporomandibular joint disorder, characterized by elongation of the coronoid process, which may cause limited mandibular movement as a consequence of interference between the hyperplastic coronoid process and the medial surface of the zygomatic arch.

Methods:

Mandibular coronoid process hyperplasia commonly affects males in the second decade of life and the exact aetiology and pathogenesis is unknown. The condition can be uni- or bilateral. Progressive painless reduction in mouth opening is the main clinical finding and computed tomography is the most reliable imaging modality for confirming the diagnosis.

Results:

Surgical intervention involving coronoidectomy and long-term intensive postoperative physiotherapy is the treatment of choice for mandibular coronoid process hyperplasia with impingement on the zygomatic bone and limited mouth opening. However, surgically induced fibrosis and the tendency for mandibular coronoid process regrowth may cause relapse and renewed limited mouth opening. Vigorous physical therapy should therefore be initiated shortly after surgery.

Conclusion:

The purpose of this case report is to present the clinical and radiographic features of elongated mandibular coronoid process in an 18-year-old male with limited mouth opening, and to discuss the various surgical treatment modalities.
