Kemampuan penalaran kreatif matematis merupakan kemampuan yang penting untuk dikuasai siswa. Kenyataannya, kemampuan penalaran kreatif matematis siswa cenderung bermasalah. Salah satu hal yang diyakini berpengaruh terhadap kesulitan siswa dalam memecahkan masalah pada matematika adalah beban kognitif intrinsic yang dihadapi. Oleh karena itu, penelitian ini bertujuan untuk mengungkapkan secara mendalam gambaran kemampuan penalaran kreatif siswa ditinjau berdasarkan beban kognitif intrinsic. Penelitian ini menggunakan pendekatan kualitatif dengan desain fenomenologi. Subjek penelitian ini adalah siswa kelas VIII di salah satu MTs Negeri di Kabupaten Lima Puluh Kota, Provinsi Sumatera Barat yang telah mempelajari materi bangun ruang sisi datar. Data dikumpulkan melalui teknik tes dan wawancara. Hasil penelitian menunjukkan bahwa siswa yang memiliki beban kognitif intrinsic rendah dapat melakukan penalaran kreatif matematis dengan cukup konsisten. Siswa yang memiliki beban kognitif intrinsic sedang cukup bisa melakukan penalaran kreatif matematis tetapi belum konsisten. Sedangkan siswa yang memiliki beban kognitif intrinsic tinggi hampir tidak dapat melakukan penalaran kreatif matematis. Sebagai kesimpulan, diperoleh bahwa semakin rendah beban kognitif intrinsic yang dialamisiswa, semakin baik kemampuan penalaran kreatif matematis yang ia miliki. Berdasarkan kesimpulan tersebut, direkomendasikan untuk melakukan penelitian yang mengacu kepada penggunaan desain pembelajaran yang tepat untuk mengembangkan kemampuan penalaran kreatif matematis siswa pada masa yang akan datang. Mathematical creative reasoning is an essential ability for students. In reality, students' mathematical creative reasoning skills tend to be problematic. One thing that is believed to affect students' difficulties in solving problems in mathematics is the intrinsic cognitive load they face. Therefore, this study aims to describe students' creative reasoning abilities regarding intrinsic cognitive load in depth. This study uses a qualitative approach with a phenomenological design. The subjects of this study were students of class VIII from one of the state Islamic junior high schools in Lima Puluh Kota Regency, West Sumatra Province, which studied the materials for flat and solid geometry. Data was collected through test and interview techniques. The study results show that students with low intrinsic cognitive load can consistently perform creative mathematical reasoning. Students with moderate intrinsic cognitive load can do creative mathematical reasoning but are inconsistent. Meanwhile, students with a high intrinsic cognitive load can almost not do creative mathematical reasoning. In conclusion, it is found that the lower the intrinsic cognitive load experienced by students, the better their creative mathematical reasoning abilities will be. Based on the conclusion, research is recommended to use suitable learning designs to develop students' mathematical creative reasoning skills in the future.

The ‘Late-Swelling’ peach is an important cultivar due to its attributes of fruit quality, such as handling ability and late harvest season. Peaches rapidly deteriorate during storage, which shortens their shelf-life. The preservation of quality traits of ‘Late-Swelling’ peach during handling and storage investigated. Fruits harvested in the early ripe stage (last week of June) were either dipped in jojoba oil (JO) 500, 1000, and 1500 ppm and salicylic acid (SA) 100, 200, and 300 ppm, then stored at 5+1 °C and 85% RH for 35 days besides 7 days as shelf-life the fruits were examined every 7 days until the end of the experiment. Positive influences were observed for JO and SA on the different chemical and physical characteristics of the peach fruits under study especially those related to storability and fruit quality. All fruits treated with JO 1500 and 1000 ppm, and SA 300 ppm maintained the fruit firmness, hº, total acidity, and ascorbic acid over the whole storage period, in addition to the lowest decay and weight loss, as well as maintaining the fruit sensory quality and decreased peroxidase [PPO] activity while increasing polyphenol oxidase [POD], catalase [CAT], and ascorbate peroxidase [APX] activities compared with the control at the end of shelf-life period. In conclusion, our results suggest using JO and SA to enhance and prolong the storability of peach fruits at 5+1 °C and 85% RH.

Authors: Dutta Pooja , Wadhawan Gaurav , Arora Raghav , Sharma Shruti 
Published: June 2023

Background: Hollow viscus perforation is suspected when radiographs show the presence of gas under diaphragm and is usually an indication for surgical abdominal exploration. This is significant because in cases of hollow viscous perforation, plain radiography may be used as the first line of diagnosis. Concerns regarding diagnosing those 30% cases of hollow viscus perforation which was not detected by the plain radiography.
Methods: A bound prospective study of patients who were managed for perforated hollow abdominal viscus, when no abnormality was appreciated on radiographs, confirmation was done either on the basis of clinical examination, further investigations or by exploratory laparotomy performed on basis of selection of cases.
Results: Based on the study, 15 patients were found with no gas under diaphragm on radiographs and perforation was confirmed on the grounds of clinical, physical examination, further investigations or by exploratory laparotomy on basis of cases. The results obtained in the present study shows male predominance, duodenal perforation being the most common perforation amongst hollow viscus perforations and age group of 20-40 years were affected mainly.
Conclusions: It is important to note that not all the cases of pneumoperitoneum indicate perforated abdominal viscus or vice versa. This study highlights the difficulty in pre-operative diagnosing pneumoperitoneum with upright chest and abdominal X-rays provided its sensitivity varied from 50-98%.

A prospective study to estimate the outcome of patellar fracture fixation with suture material of high resistance properties
Authors: Sain Ajay , Mathur A. K. , Jangir Rajat , Saini Rajat , Thakan Somya 
Published: June 2023

Background: Patella fractures make from 0.5% to 1.5% of all bone fractures. The most common fracture type, transverse fracture, impairs knee extension mechanics due to fragment displacement. In the years that followed, newer procedures were pursued in order to alleviate the aforementioned difficulties. K-wires were successfully replaced with cannulated screws. Furthermore, cerclage wiring was replaced with alternative implants without jeopardising the figure-of-eight tension band build.
Methods: A prospective study was conducted over a period of 18 months to evaluate the outcome of patellar fractures fixation with newer techniques and sutures. The study had 35 participants.
Results: This study included patients in the age group of 21-77 years. Among the total of 35 patients in the study, Maximum number of patients in our study were in the age range of 41-60 years which comprised 42.86%. In this study of 35 patients, 20 were male patients and 15 patients were female i.e. 57.14% of our study group comprised of male patients while 42.86% comprised of female patients.
Conclusions: The above study clearly demonstrates that the high resistance suture materials can be used as a potential alternative or may even be better to the existing prevalent fixation of patella fractures with stainless steel and wires. Fibertape fixation presents a lot of advantages over the traditional stainless steel and wire fixation. Biomechanically, fibertape has demonstrated tensile strength and stiffness equal to stainless steel and in certain specific parameters proved even more stronger than the stainless steel.
