Выполнен анализ доли кривоствольных деревьев у климатипов сосны обыкновенной ( Pinus sylvestris L.) в географических культурах Богучанского лесничества с разными почвенными условиями в южной тайге Красноярского края. В суглинистой почве она оказалась меньше, чем в песчаной, где древостои западных и южных климатипов гораздо чаще подвержены влиянию различных стрессовых факторов, вызывающих в молодом возрасте искривление ствола, в том числе и из-за замещения центрального побега. На суглинистых почвах южных климатипов лесостепных территорий доля таких деревьев значительна. У климатипов из восточных регионов России (Сибирь, Забайкалье, Дальний Восток) и из таежной зоны европейской и азиатской частей ареала сосны она в основном невелика (0-20 %). С увеличением северной широты мест происхождения климатипов, снижением массы исходных семян (из которых выращивались географические культуры) доля прямоствольных деревьев возрастает у потомств климатипов в разных почвенных условиях в географических культурах.
The analysis of crooked trees proportion of Scots pine ( Pinus sylvestris L.) climatypes was conducted in the provenance trial of Boguchansky forestry district with different soil conditions in the southern taiga of Krasnoyarsk Krai. Averagely, the results of the study showed significantly lower proportion of crooked pine trees in conditions of loam soil, than in conditions of sandy soil. The plantations of western and southern pine climatypes are exposed to different stress factors in conditions of sandy soil. As a result, in young age trees had contortion of stem, including replacement of central shoot. The southern climatypes from forest-steppe territories are differ with high proportion of crooked trees on sandy and loam soils. There are differences in regularities of stem shape variability in the different soil conditions. The significant proportion increase of trees with straight stem was revealed with eastern longitude of origin place increasing in conditions of sandy soil. Mainly, the climatypes from eastern regions of Russia (Siberia, Zabaikalie, Far East) have small percentage (0-20 %) of crooked trees in the provenance trial of Boguchany forestry. The more northerner latitude of climatypes origin places is - the more proportion of trees with straight stems on experimental plots with different soil condition is. The posterities of Scots pine from northern, middle and southern taiga, from European and Asian parts of species range, have small percentage of crooked trees.

Cel pracyW niniejszym artykule skoncentrowałam się na omówieniu obowiązków przedsiębiorstw produkcyjnych odnoszących się do ochrony wód, w tym dotyczących jakości odprowadzanych ścieków, a także zamkniętego obiegu wody. Rozważania osadziłam w kontekście zarządzania zasobami wodnymi, w tym przede wszystkim z punktu widzenia instrumentów tego zarządzania w postaci: opłat za usługi wodne oraz - w ograniczonym zakresie – zgód wodnoprawnych i kontroli gospodarowania wodami.
W publikacji zwróciłam uwagę, iż mimo dążenia ustawodawcy do zwiększenia efektywności działań na rzecz ochrony wód, w tym poprzez zmiany legislacyjne, wprowadzone m.in. ustawą o rewitalizacji rzeki Odry, to przepisy prawne stanowią barierę do realizacji celu ochrony wód.
Opracowanie wskazuje na proponowane kierunki zmian legislacyjnych. Istotne jest, aby obok nałożenia na przedsiębiorców produkcyjnych ustawą obowiązków, przepisy prawne zapewniały możliwość realizacji tych obowiązków.Materiał i metodyPodstawową metodą badawczą była metoda dogmatyczna, polegająca na badaniu przepisów prawa krajowego celem ustalenia ich rzeczywistej treści. Oparłam się na aktach normatywnych, poglądach doktryny oraz orzecznictwie sądów.Wyniki i wnioskiPrzeprowadzone badania pozwoliły mi na wyciągnięcie wniosków, co do konieczności dalszych zmian legislacyjnych. Mimo licznych zmian dokonywanych na przestrzeni ostatnich lat w intencji zwiększenia ochrony wód, praktyka pokazuje, że w tym aspekcie jest jeszcze wiele do zrobienia. Postulowane w niniejszym artykule zmiany legislacyjne, powinny zostać dokonane nie tylko w ramach ustawy Prawo wodne, ale i szeregu innych aktach prawnych związanych z gospodarką wodną, w tym w regulacjach dotyczących utrzymania czystości i porządku w gminach, zbiorowego zaopatrzenia w wodę i zbiorowego odprowadzania ścieków, czy także dotyczących planowania i zagospodarowania przestrzennego.

Authors: West Boma A. , Wonodi Woroma 
Published: January 2025

Background: Infantile colic is a functional gastrointestinal disorder not explained by organic or biochemical abnormalities. The aim of the study was to assess the knowledge and practice of infantile colic management among mothers in Southern Nigeria.
Methods: It was a cross-sectional study carried out over one-year period using interviewer-administered questionnaires.
Results: Of 327 mothers recruited, most were of age group 28-37 years 204 (62.4%), had tertiary level of education 226 (69.1%), with parity of two 214 (65.4%) and were presently nursing infants of 1-12 months of age 227 (69.4%). Majority 259 (79.2%) lived in urban areas and belonged to the upper socioeconomic class 163 (49.8%). Most mothers 249 (76.1%) had heard of infantile colic majorly from parents/relatives/in-laws (29.1%). Majority of them said colic was a physiologic process 201 (82.0%) while 142 (58.0%), due to gas in the intestines. Incorrect knowledge of features of colic included vomiting, passage of green-coloured stools and fever. Most mothers had good knowledge of infantile colic (44.3%) and this was significantly associated with higher level of education and socioeconomic class. Most children 206 (63.0%) brought to the clinic had had infantile colic which started mostly at 0-4 months 223 (68.2%) and resolved by 3-5 months of age 171 (52.3%). The most common treatment practices were the use of nospamin (38.1%) and grippe water (33.5%), prescribed mostly by healthcare workers (27.3%) and purchased from chemist shops (71.8%).
Conclusion: There was good knowledge of infantile colic among mothers in the study. However, there is still need to increase public enlightenment on the benign and self-limiting nature of infantile colic.

Published: January 2025

Background: Hearing is a special sense and one of the most important components of communication. The ability to communicate and acquiring skills largely depends on the ability of hearing. Hearing impairment can have a substantial influence on a child's speaking ability, language development and social skills. Early detection and timely initiation of treatment for childhood hearing loss is very crucial as inadequate auditory input during first few years of life irreversibly delays the language skills for communication and reading. This study aimed to predict the frequency of hearing impairment in neonates with indirect hyperbilirubinemia.
Methods: This was a cross-sectional study conducted at the Neonatal intensive care unit (NICU) and Special care neonatal unit (SCANU) of Bangladesh Shishu Hospital and Institute, Dhaka, Bangladesh during the period from January 2020 to December 2021. In this study, we included 85 hospitalized neonates with hyperbilirubinemia based on the selection criteria.
Results: The mean age of the patients was 5.6 (±1.6) days. Pre-term babies were 63.5% and 36.5% were termed babies. Among all patients, 49.4% and 43.5% of patients had indirect bilirubin levels from 15 to<20 mg/dl & 20 to<25 mg/dl respectively. Among 11 hearing-impaired neonates, 3 (27.2%) had mild to moderate impairment, 6 (54.5%) had moderate to severe impairment and 2 (18.1%) had severe to profound hearing impairment. Sepsis, ototoxic drugs and indirect hyperbilirubinemia were independent predictors of hearing impairment.
Conclusions: This study concluded that indirect hyperbilirubinemia of≥15 mg/dl in preterm and≥20 mg/dl in term neonates is an important predictor of hearing impairment in neonates.

Published: January 2025

Background: The perfusion index (PI) has been found to be a reliable indicator of peripheral perfusion and can be used to monitor perfusion in neonates undergoing surgical procedures. To study correlation of perfusion index with the need for post op mechanical ventilation, ICU care and inotropic support in neonates undergoing surgery.
Methods: Eighty neonates posted for surgery were enrolled after taking proper written informed consent from the parents. HR, BP and SPO2 and PI were recorded at 3 minutes interval for the first 30 minutes of surgery, followed by every 5 minutes till the end of procedure. Neonates requiring admission in the Department of Pediatrics were shifted to the Neonatal ICU or ward. Post-operative vitals were monitored initially every 30 minutes for first 24 hours followed by 2 hourly.
Results: There was a statistically significant association between PI and need for post-op mechanical ventilation (MV). Duration of post-operative MV based on PI showed no significant difference. A lower PI was strongly correlated with an increased likelihood of requiring ICU-level care post-operatively, but not the duration of ICU stay. There was a potential association between PI and the requirement for inotropic support. Mortality rate was higher in patients with low PI, but not statistically significant.
Conclusions: Low PI in neonates is associated with poor outcome in terms of need for ICU stay, need of postoperative mechanical ventilation and inotropic support.

Published: January 2025

Aim. To identify predictors of the development of pulmonary hypertension (PH) in the subacute period of myocardial infarction (MI) in young and middle-aged males to improve preventive measures.Materials and methods. We studied the results of treatment of male patients aged 32–60 years with a verified diagnosis of MI. Based on echocardiography findings and detection of PH at the end of the third week of MI, the patients were divided into the study group (patients with PH) and the comparison group (patients with a normal pressure in the pulmonary artery). In the studied groups, a comparative assessment of various parameters was performed, and an analysis of the risks of developing PH using the Pearson’s chi-squared test was conducted.Results. We found that the risk of developing PH in the subacute period of MI was significantly affected by certain parameters of peripheral hemodynamics, the presence of bradycardia, and the calculated value of total pulmonary resistance. The main parameters of the lipid profile were found to be significant predictors of PH in the subacute period of MI, along with some parameters of electrolyte metabolism (sodium and magnesium in the first 48 hours of MI, potassium and calcium at the end of the third week of the disease). We established the presence of a reliable relationship between several parameters of the structural and functional state of the myocardium both in the first 48 hours of MI and the end of the third week of the disease with the risk of developing PH in the subacute period of MI.Conclusion. The identified predictors make it possible to determine patients with MI who are at an increased risk of PH to timely diagnose and treat the disease and improve the prognosis.
New Crush Testing Method to Evaluate Proppant Performance Under Downhole Conditions
Authors: Nguyen T. C. , Dong T. N. , Yoo H. , Thieu T. K. 
Published: January 2025

Abstract
The main objective is to present a new crush testing method which, in contrast to the American Petroleum Institute (API) Crush Test, determines the proppant's ability to maintain its original size at specific applied pressures. This new crush test provides a better methodology for comparing and selecting a proppant type for hydraulic fracturing to maximize well performance and drastically improve cumulative well output and decline curve forecasting.
Four samples of 40/140 mesh proppants were utilized. Initially, an API Crush Test was conducted to establish reference data. Subsequently, the new crushing testing method was performed, isolating each mesh size to determine the size's Retention of Original Size % under specific applied pressures. The Weight Score for each size was calculated by multiplying the Retained Original Size % by its distribution %. To assess total sample strength, an Effective Weight Score (EWS) was introduced by summing all weight scores together. Proppant permeability before and after crushing was measured to gain insights into performance under pressures ranging from 4,000 to 10,000 psi. Correlations between the EWS and permeability reduction were then established to enhance estimation of proppant performance under downhole conditions.
Results indicate that the samples #1, #2, #3, and #4 passed the API Crush Test under pressures of 7,000, 8,000, 10,000, and 11,000 psi respectively, assigning them K-Values (or K-Factors) of 7K, 8K, 10K, and 11K. However, it was observed that the K-Value is dictated by the smallest size in the sample, and therefore the manipulation of the distribution, especially the smallest sizes (i.e. 140-mesh) and larger sizes (i.e. 45 mesh), can dramatically alter the K- Value. Consequently, the API Crush Test was deemed unsuitable for assessing proppant strength or comparing samples.
The new crush testing method utilizes the EWS to indicate the percentage of a sample that maintains its original size under a specific pressure. Unlike the API Crush Test which grades the sample using the smallest size, the EWS simply provides the proportion of the entire sample that remains intact versus that which is crushed into smaller sizes. This makes the EWS a more reliable parameter for comparing sample strengths. Applying the new crush testing method to the four sand samples yielded vastly different results than the API Test: EWS values under 8,000 psi of 55.5%, 58.7%, 83.9%, and 85.7%, respectively. Strong correlations were observed between EWS values and permeability reduction, further supporting the efficacy of the new crush testing method for evaluating proppant performance.
The new crush testing method offers a superior methodology compared to the API Crush Test for selecting proppant types for hydraulic fracturing. Its implementation promises to maximize well performance, significantly improve cumulative well output, and enhance decline curve forecasting.
Utilizing Empirical Data and Theoretical Modeling to Build a Bigger Box and Increase Production

Published: January 2025

Abstract
Within the Permian Basin in Texas, the San Andres generally garners attention as a produced water disposal zone in the Midland and Delaware Basins or as a case study for enhanced oil recovery methods. The horizontal well development in the Northwest Shelf of the Permian Basin has steadily increased production to over 40,000 BOPD amongst several operators deploying replicable drilling programs followed by standard completion methodologies.
Initial technical focus was on how to reduce the water cut and optimize oil production by properly selecting well location. Additional work looked to improve results by analyzing theoretical well placement and model the fracture geometry and production against an existing well. As with any probabilistic workflow, the results were mixed with petrophysical heterogeneity being the primary determinant of the model accuracy (Yang et al. 2019).
This paper presents a comprehensive workflow based on a multi-well/multi-section development with over ten years of production history. All wells target the San Andres formation thus allowing for a consistent geologic reservoir model as field development expanded over time. The development timeline is organized into distinct time periods (2013-2016 (I), 2017-2020 (II) & 2021-2023 (III)) that are grouped according to well design and completion parameters. Phase III operations have increased Child well production +50-80% greater than the Parent wells and simultaneously decreased water production. The operator thus reduced the payback period for each new well drilled while increasing proved undeveloped (PUD) acreage.
