Determining participation eligibility for amusement attractions
Authors: Woodcock Kathryn
Published: May 2023

Amusement attraction participation eligibility requirements may be expressed in terms of age, height, weight, health condition, (dis)ability, and combinations of these, and potentially other criteria. Restrictive eligibility criteria can protect manufacturer and operator from liability for injury, since no guest could sustain injury without exposure to the ride. However, new forms of liability have emerged, through litigation under general human rights codes or specific regulations of the Americans with Disabilities Act. This paper describes and compares two approaches to more specifically determining participation eligibility for guests with disabilities and health conditions: the medical approach and the human factors engineering approach. Although many conditions are manifest in a range of severities, the medical approach will either impose the most restrictive eligibility on all guests with the same disability type, or require park personnel to make diagnostic determinations outside their expertise, and requires compilation of data about every disability and condition. The human factors engineering approach identifies functions to be performed by the guest to fulfill the ride experience. Clear description of functions and risks will enable guests to determine whether they are able to safely ride, in consultation with their own advisors. The approach to determining eligibility affects not only whether a particular guest can ride, but also operational practices that affect guests’ relationship with the park
Global incidence of theme park and amusement ride accidents
Authors: Woodcock Kathryn
Published: May 2023

This study describes worldwide occurrence of accidents involving amusement rides. The study compiled and

classified reports in international media coverage for a one-year period, analysing event type, ride type, op-

eration type, and regional location. Media reports provided limited detail and almost certainly omitted some

events but remain the only publicly available data on a global scale.

Over the year, 182 accident events were reported, from 38 countries, of which 51 events involved a fatality.

Mechanical rides and roller coasters were involved in 87 events. Fixed-site rides (amusement and theme parks),

mobile rides, and waterparks were involved with a similar number of cases. The most common event type with

fixed-site and mobile rides was ride malfunction (63 cases). In waterparks, drowning or near-miss of drowning

was most common (27 cases). Just 11 reports involved improper rider action, 12 involved failure of reasonable

action, and 11 involved medical conditions or reactions.

Occurrence as a proportion of attendance was highest in Latin America, predominantly involving mechanical

non-tracked rides; water attractions predominated in North America. Lower prevalence of malfunctions in North

America suggests value of professional development for mechanics and inspectors and strong regulation to

promote international safety standards.

Pilot scale black liquor concentration using pressure driven membrane separation
Authors: RAE SAM , RICHARDS ELLA , KLEIMAN-LYNCH MAX , KELLER BRENT , MACDONALD BRANDON
Published: May 2023

Black liquor concentration using pressure driven membrane separation has long been proposed as a means of achieving energy savings and breaking production bottlenecks. To date, limitations in membrane perfor-mance and stability under black liquor process conditions have prevented those promises from being realized outside of tightly controlled laboratory settings.
In this work, we describe the first successful pilot scale field deployments of a membrane system for black liquor concentration. Using a purpose-built system and commercial sized, spiral wound graphene oxide membrane ele-ments, we have logged nearly 6000 h of runtime across deployments to multiple mill sites. We demonstrate concentration of black liquor from 14% to >20% total solids, while generating permeate water comparable in quality to that of evaporator condensate and an 81% reduction in energy consumption relative to evaporation. At a commercial scale, these results translate to $2 M/year in net energy savings for a typical mill, as well as an opportunity to support production increases or mill expansions. These results represent a significant leap forward in the ability of membrane systems to deliver substantial value via black liquor concentration.
ПОЛЬСЬКА ОПЕРАЦІЯ НКВС 1937–1938 РР.: «СПРАВА ПОЛЬСЬКОГО КЛУБУ» В ХАРКОВІ

Published: May 2023

Мета. У статті досліджуються організація та причини Польської операції НКВС 1937–1938 рр. Перебіг цього злочину радянської влади розглядається на прикладі «Справи Польського клубу» в Харкові, котрий був визнаний осередком «контрреволюційної та шпигунської діяльності». Методи. Дослідження написано з використанням загальнонаукових (аналіз, синтез, узагальнення) та спеціально-історичних (історико-типологічний, історико-системний, історико-порівняльний, історико-генетичний) методів. Результати. У статті розглянуто доробок вітчизняних і зарубіжних науковців та окреслено головні тенденції у вивченні цієї проблематики. Проаналізовано Оперативний наказ народного комісара внутрішніх справ СРСР Миколи Єжова за № 00485 від 11 серпня 1937 р., який поклав початок Польській операції НКВС. Документ встановлював шість груп поляків, котрі підлягали беззаперечному арешту, міри їхнього покарання та новий особливий порядок проведення кримінального провадження. Останнє дозволило прискорити процес винесення вироків (у більшості смертельних). Визначено, що серед усіх «національних» операцій НКВС «польська» була найбільш масштабною за кількістю жертв. Йосип Сталін вважав представників «національностей іноземних держав» реальними або потенційними ворогами. Другій Речі Посполитій у майбутньому протистоянні відводилася виняткова роль, а отже, і «шпигунів», «контрреволюціонерів», «терористів» серед поляків, котрі проживали на території СРСР, було, на переконання радянського «вождя», найбільше. «Справа Польського клубу» в Харкові є прикладом сфабрикованого звинувачення цілої групи людей (поширена практика у роки Великого терору 1937–1938 рр.). Головними доказами «контрреволюційної та шпигунської діяльності» арештованих були їхні свідчення, котрі часто отримувалися із застосуванням методів морального та фізичного тиску. Таким чином, до вищої міри покарання було засуджено 28 осіб. Усіх реабілітували посмертно в 1957 р. Висновки. Радянські репресії забрали або скалічили життя окремих людей, цілих родин і навіть народів. Жертвами Польської операції НКВС 1937–1938 рр. стало щонайменше 143 810 осіб, з котрих 111 091 людину було розстріляно. Поряд із польськими комуністами, ксьондзами, колишніми землевласниками, колишніми військовими терор було поширено на звичайних селян, робітників промислових підприємств, службовців, освітян.
Elevational Gradient Effects on Microbial Distribution in Crude Oil Polluted Sites
Authors: Edamkue Israel , Chikere Chioma , Okafo Chidinma
Published: May 2023

Crude oil is a major environmental pollutant in the Niger Delta region of Nigeria due to heightened operations of the petroleum industry in this location. This comparative study of two different petroleum hydrocarbon-polluted soils from the Bodo and Tombia communities in Rivers State was carried out to determine microbial abundance (distribution) in relation to the depth and soil texture of the polluted sites. Soil samples were collected at 15 cm and 30 cm from each site. Baseline physicochemical parameters and microbial counts were determined using standard methods. Hydrocarbon utilizing bacteria were screened with 2,6-dichlorophenol indophenol (DCPIP) for crude oil degradation efficiency. The average total petroleum hydrocarbons (TPH) collected from the areas values are higher than the intervention value of 5000 mg/kg as stipulated by the Department of Petroleum Resources (DPR) in the Environmental Guidelines and Standards for the Petroleum Industry in Nigeria (EGASPIN). Microbial distribution patterns were not significantly different (p=0.08) between the topsoil and subsoil in the sites investigated. There was no significant variance in the relationship between soil texture and microorganism distribution (p=0.998). An interaction of the effects between the two independent variables produced an insignificant variance (p=0.411). Average viable culturable heterotrophic and hydrocarbon utilizing microbial counts for the sites varied considerably between 105 and 106 colony forming units per gram of soil (cfu/g) at both depths. A consortium of Pseudomonas spp., Proteus spp., Sphingobacterium spp., and Bacillus spp. isolated from the sites efficiently degraded crude oil, showing a 100% decolourization of DCPIP in Bushnell-Haas-crude oil broth. This study demonstrated that soil texture and depth affect microbial diversity and their function in crude oil contaminated sites.

Bacteria Isolated from Canada’s White Rabbit Cave Revealed Antimicrobial Activities
Authors: Walsh Monica , Ghosh Soumya , Ponce Alfredo , James Chris , Kam Gabriella , Lauriente Tanna , Yu Vincent , Safford Kirk , Cheeptham Naowarat
Published: May 2023

Caves offer a unique habitat for microorganisms, which allow the adaptation of exclusive metabolic pathways to the resources available. This environment could enable the production of primary and secondary metabolites with unique antimicrobial or enzymatic properties. White Rabbit Cave is located in the Monashee Mountain range in south-central British Columbia, a metamorphic range not known for cave and karst development. The present study has recovered bacterial isolates from the White Rabbit Cave and assessed them for their antimicrobial properties by employing the agar plug assay. One hundred and six bacterial isolates were cultivated from the collected samples, among which, five bacterial isolates displayed antimicrobial properties against a methicillin-resistant Staphylococcus aureus (MRSA) strain. Furthermore, these five isolates were identified with 16S rRNA gene sequencing and through phylogenetic analysis. It has been observed that three of them (B076, B053, and B079) were identified as Streptomyces spp. (Phylum Actinobacteria) while the other two were recognized as Paenibacillus spp. (B039) and Paenibacillus terrae (B016) (Phylum Firmicutes). To the best of our knowledge, this is the first study that identifies bacterial species with antimicrobial properties from White Rabbit Cave in the Monashee Mountain range in British Columbia, Canada.
Addressing Attrition: Multi-Level Mentorship Model
Authors: Chang Ya-Chih , Drescher Talya
Published: May 2023

Mentorship has been identified as a protective factor in early career special education teacher retention. These mentorships can be formal or informal during teachers’ first years of teaching and can support teachers in various aspects of their careers, such as navigating required paperwork and instructional practices. However, these mentorships should be individualized and consistently provided to be meaningful. To address the inconsistent mentorships that early career teachers may receive, we propose a model in which early career teachers are supported by a network of alumni to both support and retain the early career special education teaching force. In turn, the alumni are supported by university faculty in mentorship skills to fill gaps in administrative roles where special education expertise is needed. By providing support to both groups of special educators (e.g., early career, mid to late career), we hope to address the shortage of special educators by improving attrition rates of early career special educators while concurrently encouraging and promoting leadership roles for in-service special educators, filling the critical need of administrators with special education expertise.
Numerical Simulation of a Planar Model of a Ball Absorber in a Spherical Dish
Authors: Kawulok Marek , Pospisil Stanislav , Freiherrova Nela , Juracka David
Published: May 2023

This paper aims to investigate the behavior of a spherical absorber composed of two parts, an inner sphere and a supporting convex spherical dish in which the ball is placed. Considering only the planar behavior of the system, a set of governing nonlinear differential equations was derived and solved numerically. Firstly, the system is exposed to the harmonic excitation of the supporting bowl and its time response is analyzed for all time dependent variables. By gradually changing the angular frequency of the excitation, a resonance curve is obtained, which is examined in detail with respect to the changing amplitudes of the excitation force and the nonlinear behavior. The effect of internal damping and different settings of the absorber characteristics are also investigated. The effect of initial conditions without the presence of an external excitation force is also numerically analyzed by means of phase portraits for selected pairs of initial conditions.

Stillbirth and early neonatal death is quite high in Bangladesh. The current study was undertaken to find out sociodemographic and pregnancy related risk factors that may exist with cases of stillbirth and death during first 7 days of life. This was a cross sectional study conducted at Institute of Child and mother health (ICMH) between February to June 2015. Mothers delivered still birth baby at ICMH and whose babies were admitted in neonatal ward immediately after birth for delay to cry were enrolled consecutively. Data was collected by interviewing mothers and reviewing hospital records using structured questionnaire. Follow up was done till 7 days. Data analysis was done with SPSS version 14 Among a total 116 mothers 83.6% came from rural areas, 48.2% belong to 20-25 years age group with mean age 23±5 year, 46.6% had primary education, 89.7% were primipara, and 62.9% had more than 4 antenatal visits in index pregnancy. Common pregnancy related problems were anaemia (85.3%), preeclampsia (41.4%), less fetal movement (31.9%), polyhydramnios (13.8%), oligohydramnios (12.9%), premature rupture membrane (58.6%), prolong labour 48.3%), malpresentation (8.6%) and urinary tract infection in 12.1%. About 69.8% delivered at hospital, 59% had normal vaginal delivery, instrumental delivery 17.2% and caesarean section in 24.1%. About 57.8% babies were born preterm. and 55.1% were low birth weight. During first 7 days of life 32% developed neonatal sepsis and 32.8% died. Cause of death as recorded was perinatal asphyxia (55.17%), hypoxic ischemic encephalopathy 17.2%, low birth weight with perinatal asphyxia in 35.6% and meconium aspiration syndrome 4.5%. Stillbirth and early neonatal deaths are obstetric catastrophe and has common overlapping risk factors. Risk specific interventions with special emphasis on improvement of quality of care throughout the phases of pregnancy, delivery and postpartum period is recommended

Published: May 2023

Coronavirus disease (COVID-19) has emerged as a global threat. The disease largely attacks adults with higher mortality among the aged and compromised people. Although previous coronavirus havocs caused significant number of maternal and neonatal demise, most pregnant cases with COVID-19 infection are either asymptomatic or with mild symptoms only. This pandemic brought significant disruption of essential antenatal and intranatal care worldwide. The health resources became diverted to focus on general population needs rather than the specified needs of pregnant women. Limited information is known about the effect of COVID-19 disease on pregnancy. Recent evidence indicates that pregnant women are not vulnerable group for severe COVID-19 illness. However, immunological and physiological alterations during pregnancy expose women more vulnerable to SARS-CoV- 2 infection in comparison to general population.Covid-19 pandemic has created a global crisis causing great challenges for pregnant women and their obstetricians. Although the due course of pregnancy is not strained by the disease itself but complications can happen in absence of proper care and caution. Both the pregnant mother and care-giver should be vigilant and the obstetric management should be implemented following evidence based standard protocol.

Nonsurgical Management of Mullerian Agenesis with Saline Injection and Sustained Digital Pressure: A Case Series
Authors: Ishrat Shakeela , Deeba Farzana , Anwary Shaheen Ara , Banu Jesmine , Fatima Parveen
Published: May 2023

When a woman with mullerian agenesis presents with blind or absent vagina, management options include surgical vaginoplasty or non surgical self dilatation. Vaginal dilation should be the first line management of mullerian agenesis. Because of the need for motivated, mature patients and long term dilatation and follow up, gynecologists usually go for surgical vaginoplasty. We tried a novel approach to nonsurgical dilation of vagina in the cases of mullerian agenesis. We injected normal saline into the potential space of vagina between urethra and rectum and applied digital pressure daily for 14-15 days. This procedure created a vaginal space which was to be further dilated by regular coitus and/ or vaginal dilators. We are presenting here a series of three cases of mullerian agenesis managed by non surgical vaginal dilatation, facilitated by prior saline injection and sustained digital pressure.

Long-term Clinical Course and Prognostic Factor of Branch Retinal Artery Occlusion
Authors: Shin Daeun , Kim Yeji , Kim Chul Gu , Kim Jong Woo , Kim Jae Hui
Published: May 2023

Purpose: To investigate the long-term clinical course and prognostic factors of branch retinal artery occlusion (BRAO).Methods: The medical records of patients diagnosed with BRAO were reviewed retrospectively. Visual acuity (VA) and central retinal thickness (CRT) at diagnosis were compared with those measured at the final visit. Patients with a decimal VA ≥ 0.6 (good prognosis group) were compared with those with a decimal VA ≤ 0.5 (poor prognosis group) at the final visit.Results: Fifty-five patients were enrolled and the mean follow-up period was 45.8 ± 27.8 months. The mean logarithm of minimum angle of resolution improved from 0.53 ± 0.57 at diagnosis to 0.36 ± 0.61 at the final visit (p = 0.026). The decimal VA was ≤ 0.1 in 13 (23.6%) patients, ≥ 0.2 and ≤ 0.5 in 16 (29.1%) patients, and ≥ 0.6 in 26 (47.3%) patients at diagnosis; the respective values were 9 (16.4%), 8 (14.5%), and 38 (69.1%) at the final visit. The mean CRT significantly decreased from 273.9 ± 34.7 µm at diagnosis to 248.9 ± 27.0 µm at the final visit (p < 0.001). The poor prognosis group (n = 17) was older (p = 0.044) and had a higher incidence of papillomacular bundle involvement (p < 0.001) than the good prognosis group (n = 38).Conclusions: Patients with BRAO generally showed relatively favorable long-term outcomes. However, the final VA was ≤ 0.1 in 16.4% of them, suggesting the need for further treatment modalities to improve the outcome of patients with a poor prognosis.
Risk of Developing Congenital Glaucoma in Premature Infants with Large Cup/Disc Ratio
Authors: Choi Eun Jung , Park Ji Seok , Shin Ji Hye , Jang Mi-Young , Hwang Young Hoon , Kim Kyoung Nam
Published: May 2023

Purpose: To investigate the risk of congenital glaucoma development in premature infants with large cup/disc ratios: a long-term follow-up study.Methods: The medical records of premature infants with cup/disc ratios of at least 0.3 were retrospectively reviewed. Ophthalmic examinations, including measurements of intraocular pressure (IOP) corneal diameter, and dilated fundoscopy, were periodically performed. Changes in the cup/disc ratio from the first examination to the last follow-up were sought, and clinical factors associated with such changes were analyzed. In addition, glaucoma development was investigated.Results: Seventy-four patients were included; they were monitored for up to 33.96 ± 19.86 months (based on corrected age). At first examination, the mean IOP was 17.12 ± 4.01 mmHg and the horizontal corneal diameter 10.34 ± 0.83 mm. The mean cup/disc ratio was 0.54 ± 0.14 at the first visit and increased significantly to 0.57 ± 0.14 at the last follow-up (p < 0.001). A small baseline cup/disc ratio was associated with a greater change in the cup/disc ratio (regression coefficient β = -0.111, p = 0.028). We found no significant association of such change with gestational age, birth weight, IOP, or corneal diameter. We encountered no case of congenital glaucoma.Conclusions: Even if the cup/disc ratio is at least 0.3 in premature infants, the risk of glaucoma does not seem to be high if the IOP is not high. Prospective studies on more patients are needed.

Authors: Lee Hansang , Lee Chul Hee , Choi Eun Young , Lee Junwon , Kim Min
Published: May 2023

Purpose: We report a rare case of deep vein thrombosis and pulmonary embolism that occurred following 2 weeks in the prone position after a trans pars plana vitrectomy with gas tamponade to treat rhegmatogenous retinal detachment.Case Summary: A 49-year-old man without a remarkable medical history visited our clinic complaining of gradual vision loss on the inferior side of the left eye. In fundus examinations, rhegmatogenous retinal detachment involving the macula with multiple tears was noted. After trans pars plana vitrectomy with gas tamponade, the patient was encouraged to maintain a prone position for retinal reattachment. However, after 2 weeks in the prone position, he complained of right calf pain and swelling. The department of cardiovascular surgery was consulted immediately and deep vein thrombosis and pulmonary embolism were diagnosed. After deep vein thrombectomy and anticoagulation therapy, the lower extremity symptoms improved and the patient was stable during follow-up with a well attached retina.Conclusions: When prolonged prone positioning after retina surgery is necessary, careful monitoring for the possibility of deep vein thrombosis and pulmonary embolism is required, especially in high-risk patients.

Published: May 2023

O quadro inflamatório sistêmico exacerbado gerado pela COVID-19 está associado a desordens na hemostasia. O objetivo deste estudo foi de realizar uma busca, síntese e discussão acerca de estudos relacionados às consequências da COVID-19 e as sequelas hemostáticas geradas após a infecção pelo SARS-CoV-2. Estudo observacional descritivo, do tipo revisão integrativa de literatura. Seis estudos foram incluídos nesta pesquisa. A COVID-19 provoca um processo inflamatório associado a hipercoagulabilidade, ativação plaquetária e disfunção endotelial. O aumento de D-Dímero parece refletir na formação de coágulos pela viremia e excesso de citocinas decorrente do processo inflamatório. Em contrapartida, valores elevados persistentes de D-dímero mesmo após hospitalização por COVID-19 podem não estar associados a risco de TEV (em indivíduos sem risco de trombose). O tratamento rotineiro de todos os pacientes com tromboprofilaxia pós-alta hospitalar pode não ser necessário, enquanto visando pacientes de alto risco pode ser suficiente. A alteração no eixo FVW(Ag)/ADAMTS13 está relacionada com um estado pró-trombótico e é muito presente em pacientes com COVID-19. Há envolvimento sustentado de células endoteliais, atividade de coagulação e inflamação crônica no decorrer da doença, além de potenciais danos microvasculares. Os idosos são mais susceptíveis a complicações no curso da COVID-19. Já a população pediátrica, em sua maioria, apresenta casos leves e/ou assintomáticos. Porém, todas as faixas etárias estão sob influência da presença ou ausência de comorbidades e outros fatores individuais e ambientais. O cuidado com pacientes acometidos da COVID-19 deve ir além da alta hospitalar, necessitando de acompanhamento, avaliação e reabilitação contínua.
SUSTAINABILITY, EQUITY AND EFFECTIVENESS IN PUBLIC FINANCING FOR HEALTH IN UGANDA: AN ASSESSMENT OF MATERNAL AND CHILD HEALTH SERVICES
Authors: OKUNGU Vincent , MWEU Marshal , MANS Janine
Published: May 2023

The aim of this assessment was to
understand whether financing for maternal, child health and immunization
services are sustainable, efficient, effective and equitable. Data
sources included various national and international reports related to
financing maternal and child health services. The results show that funding for
maternal and child health (MCH) services are unsustainable over the long term
because the main financing source are out-of-pocket (67% of total for MCH).
However, Uganda shows higher efficiency in delivery as it has the lowest
average cost per delivery (USD 50) compared to USD 70 (Kenya) and USD 95
(Ghana). Overall, MCH interventions being financed show some levels of
effectiveness; e.g. maternal mortality rates dropped from 420/100000 live
births in 2010 to 343/100000 live births in 2016; under-5 mortality rates
reduced from 151/1000 live births in 2000 to 64/1000 live births in 2016. There
are however, inequities by region, age, education status and wealth index; e.g.
37% in the poorest quintile have unmet family planning needs compared to only
23% in the wealthiest quintile. In conclusion, public financing for primary
services such as MCH requires reforms to strengthen health sector performance.
The reforms should address sustainable financing, efficiency, effectiveness and
equity in service delivery.

The aim of this study is to add functional food feature to ice cream, which is a popular food, by enriching it with propolis. In addition, another aim of the study is to provide a widespread consumption potential through ice cream to propolis, which cannot be consumed raw and whose benefits and functional properties are unknown to most consumers. A mixture consisting of a total of 6 sample groups containing 0.0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% propolis powder was prepared for the ice cream mix. Ice cream samples were prepared from these ice cream mixes. Different analyses were executed for propolis, ice cream mix and ice cream samples. While only antioxidant analysis was executed for propolis samples, Dry matter, pH, titration acidity analyzes were executed in ice cream mix samples. Volume increase index, texture analysis, melting rate, antioxidant activity and sensory analyzes in propolis added ice cream samples were carried out on different days during 2 months of storage. According to the findings, while the volume increase of the ice cream samples was not affected by the storage time, the difference between the propolis concentrations was found. It was observed that the first dripping times increased with storage, while the melting rate of the ice cream decreased. There was no significant change in the meltıng rate and first drip times depending on the propolis concentrations. The texture properties of ice cream samples have changed with the addition of propolis. The hardness and stickiness values of ice cream samples changed depending on the storage time. The addition of propolis significantly increased the antioxidant activity. Antioxidant activity was changed with the addition of propolis. The phenolic content and of ice cream did not change with storage, but FRAP value decreased slightly after 60 days of storage. Storage time had a limited effect on the physicochemical and sensory properties of ice cream. Although the addition of propolis negatively affected the physical and sensory properties of ice cream, it contributed significantly to the antioxidant activity even at the lowest concentrations. With this study, the potential of propolis-added ice cream as a functional new food for consumers of all ages has been demonstrated. In line with these results, new studies should be conducted by trying different propolis extracts and different concentrations, by revealing the functionality of propolis and adding it to new other foods.

Turkey is in a very convenient position for animal husbandry in terms of both natural resources and ecological conditions. Forage crops, which has a very important place in agricultural activities, is the insurance of plant and animal production. Sainfoin is a perennial forage legume species that grown in the northern temperate regions of the world from the Mediterranean region and the Caucasus, and to Central Asia. In this study the genetic diversity of 100 genotypes representing 44 accessions from 18 different Onobrychis species (O. arenaria subsp. arenaria, O. inermis, O. petraea, O. cyri, O. iberica, O. altissima, O. vassilczenkoi, O. conferta subsp. argentea, O. alba subsp. laconica, O. biebersteinii, O. grandis, O. kachetica, O. kemulariae, O. oxyodonta, O. megataphros, O. pallasii, Onobrychis spp., and O. viciifolia) were evaluated using 8 simple sequence repeat (microsatellite) markers. Based on the results, OVK036, OVK094, OVK125, OVM033, OVK161, OVK046, OVM061, and OVK174 loci were polymorphic. The observed number of alleles per SSR locus ranged from 6 to 21 alleles (mean of 11.625). Maximum allele frequency ranged from 0.51 to 0.93 with a mean value of 0.73. The PIC value ranged from 0.124 to 0.244. The mean polymorphism information content of loci was 0.188. Genetic diversity coefficients according to the UPGMA ranged from 0.000 to 0.9375. Cluster analysis divided the 100 sainfoin genotypes into two main groups (Cluster-I and Cluster-II). All diploid genotypes (except for 1 diploid genotype) used in the study formed a separate group within Cluster-I. The results revealed that SSR markers used in this study are useful for molecular characterization and assessing genetic diversity of sainfoin accessions. The obtained SSR alleles and genetic variability in a studied certain loci provided significant information about the genetic structure of sainfoin accessions that could be used as parental lines in sainfoin breeding programs.

Published: May 2023

Tetranychus urticae Koch (Acari: Tetranychidae) birçok kültür bitkisinde ciddi ekonomik kayıplara sebep olan fitofag zararlılardan biridir. T. urticae’nin mücadelesinde genellikle kimyasal kullanımı ön plana çıkmaktadır. Ancak kimyasalların fazla miktarlarda ve uygun olmayan zaman ve dozlarda kullanımı, ürünler üzerinde kalıntı ve toksik etki bırakması nedeni ile birçok olumsuzluğa neden olmaktadır. Son zamanlarda bitkilerden elde edilen ekstraktların tarımsal zararlılar üzerindeki etki çalışmaları gün geçtikçe artmakta ve başarılı sonuçlar vermektedir. Yapılan bu çalışmada, portakal yağının ticari formülasyonu olan bir insektisitin farklı dozlarda T. urticae üzerindeki yumurta bırakma davranışına yönelik etkisi ve akarisidal etkisi araştırılmıştır. Denemeler laboratuvar şartlarında %65±10 nem ve 25±2°C sıcaklık koşullarında, fasulye yaprakları üzerinde, yaprak disk daldırma yöntemi ile 5 farklı uygulama dozu (0.2, 0.4, 0.6, 1 ve 2 ml 100 ml-1 su) kullanılarak ve 5 tekerrür olarak yürütülmüştür. Gözlemler uygulamadan 1, 24, 48, 72 ve 96 saat sonra ölü ve canlı birey sayımları alınarak yapılmıştır. Yapılan bu çalışma sonucunda T. urticae bireyleri üzerindeki en yüksek akarisit etkinin uygulamadan 96 saat sonra portakal yağının %2 konsantrasyonunda %75.56 ölüm oranı ile belirlenmiştir. 96. saat gözlemlerinde en düşük akarisit etki ise %20 ile %0.2’lik konsantrasyonda tespit edilmiştir. Buna göre çalışmada ele alınan portakal yağının konsantrasyon ve süresi arttıkça akarisit etkisinin de arttığı gözlenmiştir. Portakal yağı aktif maddeli insektisitin T. urticae’nin yumurta bırakma davranışı üzerindeki etkisine bakıldığında ise kullanılan insektisitin %2 konsantrasyonunda 96 saat sonunda 8.80±1.87 yumurta sayısı tespit edilirken aynı gözlem zamanında kontrol grubundaki yumurta sayısı 99.40±1.26 olarak belirlenmiştir. Sonuç olarak portakal yağının T. urticae üzerinde sağladığı akarisidal etki, kimyasal mücadeleye alternatif bir mücadele etmeni olarak kullanılabileceğini göstermektedir.

Authors: DEMİRCİ Ahmet Şükrü , GÜRBÜZ Başak
Published: May 2023

The impact of adding xanthan gum (0.05, 0.1 and 0.2%) biosynthesized from grape juice pomace on the physicochemical characteristics (pH, titratable acidity, total solid, water holding capacity and syneresis) of set-type yoghurt was examined during 21 days of storage period at 4 oC in this study. Textural, color (L*, a* and b*) and sensory attributes (appearance, color, texture, taste and odor) were also assessed in samples with and without biosynthesized xanthan gum. The textural properties and water-holding capacity of the yoghurt were significantly (p0.05) between the samples at the end of storage, except for the sample with 0.2% xanthan gum. The addition of the highest concentration of xanthan gum increased the a* and b* values while decreasing the L* value (p 0.05) between BX0.1% and BX0.2%, the samples with the lowest L* value. The addition of biosynthesized xanthan had no significant effect (p> 0.05) on the total solid, protein and ash content of yoğurt. Besides, the biosynthesized xanthan gum had no negative impacts on the sensory characteristics of yoghurt, except for the appearance. The findings indicated that biosynthesized xanthan may be a desirable additive since it enhances the physical characteristics of yoghurt without affecting its nutritional value or sensory properties.
