Physiological and behavioral effects of hormonal contraceptive treatment in captive, pair-bonded primates (Plecturocebus cupreus)
Authors: Karaskiewicz Chloe L , Ramirez Melissa , Bales Karen L
Published: November 2023

Hormonal contraception is an effective, reversible tool for managing birth rates in humans and nonhuman animals alike. However, manipulating reproductive hormones has behavioral consequences that can impact social and sexual behavior between conspecifics. First, we studied 18 pairs
of nonreproductive titi monkeys (Plecturocebus cupreus) to test the efficacy of a novel method of hormonal contraception (deslorelin acetate implants) on reproductive hormone cycling in females and found significant reductions in urinary estrogens and progestagens among treated females
compared to untreated controls. We then studied 35 nonreproductive pairs of coppery titi monkeys (Plecturocebus cupreus) to ascertain whether treating females with one of 2 different forms of hormonal contraception (deslorelin acetate implants (n = 17) or medroxyprogesterone
acetate injections (n = 9)) would influence the relationship between pair mates compared to the relationship between untreated females and their vasectomized male mates (n = 9). Over a 5-month period, we found no differences in affiliative behaviors between pairs containing untreated
females compared to pairs in which the female was treated with either deslorelin acetate or medroxyprogesterone acetate. Similarly, we found no differences in affiliation between pairs in the 2 treatment groups. This study is the first to examine behavioral consequences of hormonal contraception
in a pair-bonding species. The results are encouraging for captive, managed breeding colonies of such social animals, especially those used in behavioral research.

Environmental cleanliness must be a concern for all aspects of the community. In Sungai Nangka Village, RT.10, waste management is still not optimal so it has a negative impact on environmental conditions and raises various environmental problems. To follow up on this waste problem, it is necessary to have a commitment with the community in their participation to be able to manage waste so that it can be something useful and reduce environmental problems. One of the innovations in dealing with this case is through managing waste starting from the source, which can be started from the waste bank. The waste bank itself is a place for sorting and collecting waste that can be recycled and reused so that it has beneficial economic value. Apart from the waste problem, the pandemic also has an impact on the education of children in Sungai Nangka Village. Currently, formal education activities are conducted online and school children are required to study from home. This makes it difficult for children to learn because they are unable to follow the material presented online. Learning difficulties can lead to a decrease in children's achievement. Children who have problems with learning can usually be seen from several factors, namely the achievement achieved by the class group is relatively low, the results are not balanced with the effort made, and are late in doing learning assignments. The implementation of this community service activity is expected to increase public understanding of handling environmental problems, and education for children in Sungai Nangka Village, RT.10.

Published: November 2023

On October 1, 2022, an earthquake with a magnitude (M) of 5.8 occurred in the Tarutung region, Indonesia and was associated with an active fault at a depth of 10 km. The earthquake fault with dextral mechanism is suitable with the pattern of active fault movement in Sumatra in the Northeast - Southwest direction. A total of 170 aftershocks occurred within a week span with magnitude variations of 1.7 – 4.0. In addition, the Tarutung earthquake was felt by the local peoples with an intensity of IV - VI MMI and caused 1 fatality, 25 injuries, and around 900 houses were damaged. Therefore, this study studies the characteristics of seismicity and damage caused by finding an appropriate 1-Dimensional seismic velocity model. The obtained 1-Dimensional speed model has varying values at a depth of 10 km with a speed of ~5.5 km/s and 30 km with a speed of ~7 km/s. The 1-D velocity model obtained has a convergent and unique solution with an RMS value < 1.0. Based on ground motion analysis after relocation, it was found that the high PGA and PGV values were in Tarutung. The PGA results reveal a high percentage value of >10% in Tarutung. This is consistent with the damage data and at the same time confirms that Tarutung is in a seismically active area.

Published: November 2023

Semarang City is one of the cities in Central Java which has a lot of potential and tourist attractions that can be developed further. The city offers diverse destinations, including Semarang Zoo. In 2007, the Municipal Government of Semarang relocated the zoo from Tinjomoyo Zoo to a new site in the Mangkang area and renamed it Semarang Zoo. Currently, Semarang Zoo is a man-made tourist attraction. The presence of these tourist areas has a substantial impact on the local economy, benefiting the surrounding communities. To assess the post-relocation development of tourist areas, an analysis of the economic value zones was conducted using the Travel Cost Method (TCM) and the Contingent Valuation Method (CVM) to determine the total economic value of the tourist areas. The Hedonic Pricing Method (HPM) was employed to gauge tourism potential based on visitor preferences. The Gravity Model was also utilized to measure the attractiveness of both tourist areas. The sample sizes for Semarang Zoo were 110 for TCM, 105 for CVM, and 110 for HPM. The research findings revealed that Semarang Zoo has a total economic value of IDR 245,895,813,400 and the highest hedonic value of 3.050. The calculated hedonic value suggests a preference value of 3, indicating an average level of preference. Based on the calculation of spatial interactions, it shows that the biggest attractions of the Semarang Zoo are Semarang City and Kendal City.

Authors:   Ministry of Education, Mugher Raghda Abdulbaqi , Alhammadi Nafea Ali Majeed ,   Shatt Al-Arab University College
Published: November 2023

In hashing technique, a hash table and hash map represent a data structure for a group of objects to map between key and value pairs, as the hash table is affected by collision and overflow. The hash table collision and overflow can be handled by searching the hash table in some systematic fashion for a bucket that is not full. In open addressing, quadratic and random probing are well-known probe sequence algorithms for collision and overflow resolution. Key density, loading density, loading factor, collisions, overflows, keys clustering, space complexity, and time complexity are the main factors that highly affect the two algorithms during hash table systematic probing. Therefore, this project is conducted to compare the quadratic probing and random probing challenge performance in terms of the key density, loading density, loading factor, overflows, collisions, keys clustering, space complexity, time complexity using step count, the order of magnitude, the worst case, the average case, and the best case. Comparing both algorithms was performed by collecting data from an online survey about the English language proficiency of 104 students. The compression result shows that the random probing algorithm has achieved similar performance compared to quadratic probing in terms of key density, loading density, loading factor, space complexity, order of magnitude, worst case, and average and best case. While the quadratic probing algorithm has recorded less time complexity using the step count method compared to the random probing algorithm. On the other hand, the random probing algorithm has recorded fewer overflows, collisions, and key clustering compared to quadratic probing. However, the study has recommended the quadratic probing algorithm for better time complexity performance and the random probing algorithm for better performance resolving overflows, collisions, and key clustering.

A description of a method for measuring the threshold current, the minimum current at which optical emission is occurs, of chips that are part of COB (chip on board) LEDs is given. The method consists in registering with a digital camera the average values of the emission intensities of the chips at three small values of the electric current and determining the threshold currents by solving a system of equations relating the measured intensities to a function approximating the P-I characteristic in the range of low currents. The measurement method was tested on commercially available COB LEDs consisting of ten series-connected chips. It was determined that the values of the threshold current of the chips differ: for the investigated samples, the coefficient of variation ranged from 2.6% to 39.2%. As a result of the tests of COB LEDs under the action of a current of 140 mA at a maximum allowable ambient temperature of 110 °C for 11 days, it was found that changes in the average values of the threshold currents during tests correlate with changes in the current-voltage characteristics of the matrices measured in the voltage range from 17 to 24 V at which leakage current dominates: the threshold current increases for those matrices in which leakage current increases. The correlation coefficient between the relative changes in the leakage current and the average values of the threshold currents is 0.94. It is shown that the correlation coefficient between the magnitude of the decline in the luminous flux of the matrices during testing and the change in the average value of the threshold current is 0.96. The established strong correlations show the possibility of diagnosing the quality by the threshold current of individual chips in the composition of COB LEDs.

The aim of this manuscript is to describe a hybrid care model to paediatric patients on a virtual basis for dental treatment before conducting an in-person surveillance by using combined nasal/oral swabbing (NOS). This longitudinal study used a convenience sample of paediatric patients and members of the dental team from an undergraduate paediatric dentistry clinic at the University of São Paulo School of Dentistry during the COVID-19 pandemic. Firstly, parents were contacted and teledentistry was used for screening children who need dental treatment. Appointments were scheduled once a week for two months, in which a pre-COVID-19 screening was performed. Dental team and children’s parents completed a questionnaire addressing COVID-19-related symptoms. Members of the dental team and children were tested for COVID-19 before entering the dental clinic, by NOS and RT-PCR screening. Ninety-three individuals were enrolled and all of them completed the electronic questionnaire on symptoms and had NOS collected weekly, totalising 241 pairs of swabs. No participant reported COVID-19 symptoms before entering the clinic for treatment. Only one child tested positive in the third week of sampling. The hybrid care model associated with molecular testing for asymptomatics provided a safe clinical environment regarding the transmission of SARS-CoV-2.
Вплив строків сівби на вегетативні ознаки пшениці озимої в умовах Полтавської області

Проведено дослідження щодо вивчення рівня прояву ознак вегетативної частини рослин пшениці м’якої озимої залежно від строків сівби в умовах Полтавської області. Дослідження здійснювалося протягом 2019–2020 років у лабораторних і польових умовах Навчально-виробничого центру селекції та насінництва польових культур Полтавського державного аграрного університету (Полтавський район). Матеріалом дослідження обрано 75 зразків сорті та селекційних ліній пшениці м’якої (Triticum aestivum L.) озимої селекції ПДАУ й інших селекційних установ. Зразки пшениці м’якої озимої досліджувалися за такими веге-тативними ознаками: висота рослин; товщина соломини другого міжвузля; кількість міжвузлів; довжина верхнього та нижнього міжвузлів; довжина колоса; маса рослини і стебла. Виконуючи загальну характеристику властивостей щодо формування ознак вегетативних органів і їх мінливість, необхідно з ауважити, що вони, звісно, під впливом стресових кліматичних умов змінюються. При цьому, деякі ознаки зберігають певні закономірності, що можуть бути використані в сучасній технології селекційного процесу задля підвищення врожайності рослин в умовах зміни клімату. Доведено, що відмінні строки сівби мали незначний вплив на формування таких ознак: товщину соломини другого міжвузля, кількість міжвузлів, довжину колоса, масу стебла. Отже, вони є генетично детермінованими та за пізнього строку сівби мають резерви з пошуку і добору генотипів за товщею соломини другого міжвузля, більшою довжиною колоса, оптимальною кількістю міжвузлів і масою стебла. Також визначено, що довжина верхнього та нижнього міжвузля за пізнього строку сівби незначно зменшують свій рівень формування, а маса рослини, навпаки, – збільшує. Отримана інформація є важливою в селекційному процесі пшениці м’якої озимої, вивченні вихідного матеріалу та плануванні схрещувань.

In 2018‒2020, the Institute for Potato Research of NAAS of Ukraine studied the effect of different rates of application of mineral fertilizers in combination with chelated fertilizers on yield, biometric indicators of potatoes and edible properties of tubers. Chelated fertilizers were used to treat tubers during planting and foliar fertilization of new potato varieties in the Ukrainian state. The purpose of the research is to develop elements of technology for growing new varieties of potatoes for the best realization of genetic potential. Research methods ‒ field, measurement, statistical. The early-ripening variety Slauta and the medium-ripening variety Gurman responded positively to the use of fertilizers, rates and methods of their application. The Gurman variety compared to the Slauta variety had better stem-forming capacity of the tubers. On average, for the years 2018-2020, the use of chelated fertilizers together with nitroammophoska increased the productivity of the Slаutа variety to 10.2 t/ha, and the Gurman variety to 6.9 t/ha compared to the control. During 2018–2020, the percentage of the seed fraction prevailed in the crop structure. The largest number of seed tubers in the Slаutа variety was provided by the sixth variant, which yielded 313.6 thousand pieces/ha with a total weight of 16.8 t/ha with a multiplication factor of 4.7. The fifth variant also stood out, in which the number of tubers was 292.4 thousand units/ha with a total weight of 14.1 t/ha with a multiplication factor of 4.4. The number of seed tubers in the Gurman variety ranged from 182.7 to 419.4 thousand pieces/ha. The mass of tubers in the sixth variant was 16.6 t/ha with a multiplication factor of 6.4. Therefore, the largest yield of seed tubers was obtained in the variants where chelated fertilizers were used and nitroammofoska was applied when planting potatoes. In the Slauta variety, the lowest percentage of tubers damaged by soil pests was found in the sixth option, where mineral fertilizers N60P60K90 were applied, spreading + treatment of tubers during planting + treatment of plants during the growing season. In the Gurman variety, the lowest percentage of tubers damaged by soil pests was found in the fourth option, where the tubers were processed during planting and foliar feeding of potatoes was carried out. The Gurman variety is characterized by better indicators of suitability for processing into potato products.
