Research objective. To determine the influence of nutriculture medium composition and different lighting conditions on the process of tuberisation of different potato varieties in vitro. Research methods. The following methods were used biotechnological methods of plant tissue and organ culture – for obtaining and propagating plants in vitro by cuttings in test tube culture on agar medium under sterile conditions. Research results. The positive effect of different lighting conditions on the growth and development of plants in vitro was investigated. As a result of the research, a certain relationship was established between the intensity of shoot growth and tuberisation. Active tuberisation began when shoot growth slowed down or stopped altogether. On the 36th day after planting the cuttings on the nutriculture medium, the first microtubers were formed. Massive formation of microtubers was observed on the Murashige-Skoog medium with the addition of 100 % macronutrients and 2 mg/l Adenine. Adenine stimulates stolon formation and tuber initiation. The yield of microtubers was: Kimmeriia variety – 53 % (control 46 %), Kniahynia variety – 39 % (control 34 %), Slauta variety – 37 % (control 35 %). In the N1 medium variant with the addition of 2 mg/l Adenine, the yield of microtubers was: Kimmeriia variety – 51 % (control 46 %), Kniahynia variety – 37 % (control 34 %), Slauta variety – 36 % (control 35 %). Conclusions. On average, in 2021–2023, the highest number of plants that formed microtubers after transferring plants to complete darkness was observed in the Slauta variety – 97 % of plants (control 93 %), the lowest number of plants that formed tubers was found in the Kimmeriia variety – 94 % of plants (control 90 % of plants). When such microtubers were planted in the soil, the germination rate was 97–99 %, plants grew and developed well. When determining the yield and its structural analysis, there was no significant difference between the studied variants.

To determine the optimal agrotechnical measures for growing potato seed material. The following methods were used in the research: field – monitoring of hydro-physical soil properties in the experiment for growing potatoes, determining the effectiveness of combinations of row spacing, accounting for the yield; laboratory – determination of the hydrothermal coefficient (HTC), in accordance with generally accepted methods. Observations of changes in soil moisture depending on different row spacing after planting potatoes, at full germination, closing of potato tops in a row (flowering) and harvesting in 2020 show that the difference in soil moisture in the ridge (seed layer 5‑10 cm) after planting potatoes was the same and was in the range of 10.2‑10.4 mm. During the harvesting period in September, there was the least precipitation (22 mm) and the air temperature dropped to 15 0С. The reserve of productive moisture in the ridge in the tuber nest zone of 10‑15 cm was 10.1-10.9 mm. The hydrothermal coefficient during the growing season of potatoes was 1.3, and the highest average monthly HTC of 2.8 was in August. In 2022, before planting potatoes, the soil temperature at a 5‑10 cm depth was 9 0С. Subsequently, the air and soil temperature increased. During the harvesting period in September, there was the least precipitation (22 mm) and the air temperature dropped to 15 0С. The reserve of productive moisture in the ridge in the tuber nest zone of 10‑15 cm was 10.1‑10.9 mm. The hydrothermal coefficient during the growing season of potatoes was 1.3, and the highest average monthly HTC of 2.8 was in August. The research found that after planting potatoes, the lowest soil density (1.08‑1.16 g/cm3), regardless of row spacing, was in the ridge where the potato tubers were located. Thus, the determination of soil hardness in the rows, on the ridge slope and in the inter-row showed that with different row spacing, the impact of the running systems of agricultural units on the soil increases. During the harvesting period, the highest hardness of 27.4–32.4 kg/cm2 was established in the technological row spacing, a slightly lower value (15.2‑19.0 kg/cm2) was noted on the ridge slope and the lowest one (1.9‑2.6 kg/cm2) – in the centre of the ridge in the area where the tubers are located.

Published: February 2025

Background:
Revision total joint arthroplasties are physically demanding cases. Recent studies have shown increased cardiovascular stress in surgeons performing revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA) compared with primary cases. To our knowledge, no study has compared surgeon ergonomics during these cases. The purpose of this study was to analyze surgeon posture during primary and revision THA and TKA.

Methods:
We prospectively evaluated 286 consecutive cases (103 primary TKAs, 95 primary THAs, 57 rTKAs, and 31 rTHAs) performed by three high-volume, fellowship-trained arthroplasty surgeons. Throughout each case, surgeons wore a posture-tracking device to evaluate time spent slouching. The threshold for slouching was set to 30 degrees of flexion from the neutral spinal axis. Demographic and surgical factors were collected. Two-tailed t-tests and multivariate analysis were used to assess differences between groups.

Results:
After controlling for individual differences in posture, we found an increase in percentage and duration of time spent slouching between rTHA and primary THA cases (58.9% vs. 43.2%, P < 0.001; 65.1 vs. 32.6 minutes, P < 0.001). In the multivariate analysis, patient body mass index and rTHA were found to be an individual contributor to slouching percentage in THAs (P = 0.001). We found increased duration of time spent slouching between rTKA and primary TKA (80.2 vs. 45.7 minutes, P < 0.001); however, percentage time slouching showed no difference (67.1% vs. 58.5%, P = 0.175). Active fellow involvement was an individual contributor to decreased time slouching in both TKA and THA groups (P < 0.001).

Conclusions:
Surgeons performing revision total joint arthroplasty spend markedly more case time in a slouched posture compared with primary arthroplasty, particularly in patients with a higher body mass index. Awareness of the surgical and patient factors that can affect posture in TKAs and THAs can help arthroplasty surgeons gain more awareness about injury prevention and potentially help prolong their career.

The waste problem is still a hot issue in several regions in Indonesia, especially in the Landak district of West Kalimantan. Population growth is accelerating and economic growth is indicated by increased production and consumption activities. So what happened at BTN Bisma, located in Ngabang sub-district, Landak district, West Kalimantan, had problems with waste disposal. At BTN Bisma there is only one large trash can in the shape of a truck. Garbage at BTN Bisma is picked up about once a week, so that around the garbage truck bins on a daily basis you can often see garbage piled up outside the tailgate, because the trash can can no longer accommodate garbage, so garbage is scattered outside the trash bin. This sight is certainly very unpleasant, even disgusting because it smells bad. Seeing this fact, our service team has done service at BTN Bisma in the form of making organic liquid fertilizer produced from household waste. The method used in this service is to conduct house-to-house outreach about how to process waste using stacked plastic buckets which can produce organic liquid fertilizer. After being processed for two months, the waste is made into organic liquid fertilizer which is very useful for fertilizing plants, both flower plants around the house and vegetables in the garden.

Published: February 2025

A character has a close relationship to personality and can be changed by the personality that the person has. The change of the character is determined by the conflict they have which leads to the development of the character. This study was aimed to analyze the psychological conflict and the influence of the main character in Joker Movie 2019. To understand the character of the Joker in the 2019 film, this study employed two key theories: Lewin's theory of psychological conflict and Hurlock's theory of character development. Researchers gathered data by analyzing the movie and its script, utilizing documentation and note-taking techniques. The analysis itself was qualitative, applying the aforementioned theories to interpret the Joker's transformation. The finding show Joker express two kinds of psychological conflict which are approach-avoidance conflict and avoidance-avoidance one. The approach-avoidance conflict insists Joker to choose two options when the conflict occurred, they are positive and negative. Meanwhile, the avoidance–avoidance conflict make Joker choose between negative and negative choices in Joker’s conflict. That two kinds of conflict influenced Arthur’s character development. There are four determinant which affect Arthur’s character development. Physical determinant which was the appearance of Arthur made him being bullied, social determinant which Joker hard to interact with the others because of his mental illness, family determinant which Arthur realize he did not receive any love from his parents, and emotional determinant which Arthur realize his life was not a tragedy but comedy.

Post-Adoption Behavior and Adopter Satisfaction of Cats Across Socialization Likelihoods
Authors: Ellis Jacklyn J. , Janke Kyrsten J. , Furgala Nicole M. , Bridge Taylor 
Published: February 2025

Introduction: Cats with questionable sociability are routinely adopted into typical home environments, but there has been no published investigation into the welfare of these cats in their adoptive homes or the quality of the adopter experience. The objective of this study was to assess differences in post-adoption behavior and well-being between cats based on their likelihood of being socialized, as well as differences in adopter experience.
Methods: This prospective behavioral study surveyed adopters of cats assessed via the Feline Spectrum Assessment (FSA) and a randomly sampled control group (those never suspected of being undersocial) of cats with intake and adoption dates during the same period. Adopters reported on behavioral traits, situational behaviors, and adopter satisfaction.
Results: As the likelihood of being undersocial increased, cats were more fearful, less affectionate, and less amenable to approach and petting (more so by strangers, but also by their owners). Adopters of FSA cats reported being slightly less satisfied than control cat adopters. As the likelihood of being undersocial increased adopters were less likely to report a traditional home environment as the best environment for their pet than control cats.
Conclusion: This study provides evidence that cats never suspected of being undersocialized experience better welfare than undersocial cats, and their adopters are more satisfied. These results are more pronounced for cats found more likely to be undersocial by the FSA. Although it is becoming increasingly possible to find adoptive homes for poorly socialized cats, it does not appear to be in the best interest of many of these cats or adopters. The results of the FSA may be helpful for making pathway decisions for each cat; evidence suggests that at least FSA 1&2 cats should be slated for Trap Neuter Return (TNR) or barn placement unless significant progress is made in shelter.
