Feasibility study on Lepton 3.5 in terms of accuracy for measuring leaf temperature of crops
Authors: Kim Byungsoon
Published: January 2024

The precise monitoring of leaf temperature is becoming more important as crop leaf temperature is utilized more frequently for different uses such as irrigation, disease and pest detection. This study aims to explore the potential usage of a cost-effective Lepton 3.5 camera to measure the crop canopy temperature. The accuracy of the Lepton 3.5 will be compared to a FLIR E8-XT thermal camera and an MLX90614 infrared thermometer. With the usage of three devices: a custom Lepton 3.5 camera, an Implexxio LT-1T thermistor and an MLX90614, the temperature of the target leaf of a laboratory plant was automatically measured every five minutes. The data would then be recorded on a private cloud server and manually measured with a handheld FLIR E8-XT. The performance of these three devices was evaluated to the standard of a highly accurate Implexxio LT-1T thermistor using the mean absolute error and root mean squared error. Among the non-contact sensors- MLX90614, Lepton 3.5 and FLIR E8-XT- the MLX90614 sensor showed the highest accuracy. However, the Lepton 3.5 module had an accuracy of less than ±2°C, which was similar to FLIR E8-XT and much better than the error value specified for the Lepton. The low-cost Lepton 3.5 can be used to periodically measure leaf temperature with an accuracy comparable to that of an intermediate-level thermal imager.

Published: January 2024

Agriculture is grappling with water scarcity, leading to diminished crop yields, economic challenges, environmental degradation, and threats to food security. The future of agriculture hinges on the implementation of sustainable water resource management and adaptation strategies. Specifically, in arid regions, the adoption of water-efficient irrigation practices is crucial for fruit growers. This approach not only helps in conserving water but also reduces costs and ensures the vitality of orchards. The cultivation of fruit trees, especially in water-stressed areas, demands meticulous irrigation management for survival. Growers play a key role in identifying stress indicators that serve as crucial markers for monitoring tree health. Proactively addressing these indicators enables growers to maintain healthier trees, resulting in higher yields. Identifying and understanding fruit tree stress indicators play a pivotal role in enhancing orchard management practices, ultimately contributing to increased yields, cost reduction, and the promotion of sustainability. This review evaluates the effectiveness of stress indicators in gauging water stress levels. It delves into the multifaceted impacts of water scarcity on agriculture and underscores the recommendation for water-efficient irrigation practices to counteract fluctuations in water availability. In environments facing water scarcity, vigilant irrigation management coupled with the identification of stress indicators strengthens the resilience and productivity of fruit tree agriculture. This study contributes valuable insights to the ongoing discourse on sustainable horticulture in the face of a changing world.
Distinguishing Oceans of Water from Magma on Mini-Neptune K2-18b
Authors: Shorttle Oliver , Jordan Sean , Nicholls Harrison , Lichtenberg Tim , Bower Dan J.
Published: February 2024

Mildly irradiated mini-Neptunes have densities potentially consistent with them hosting substantial liquid-water oceans (“Hycean” planets). The presence of CO2 and simultaneous absence of ammonia (NH3) in their atmospheres has been proposed as a fingerprint of such worlds. JWST observations of K2-18b, the archetypal Hycean, have found the presence of CO2 and the depletion of NH3 to <100 ppm; hence, it has been inferred that this planet may host liquid-water oceans. In contrast, climate modeling suggests that many of these mini-Neptunes, including K2-18b, may likely be too hot to host liquid water. We propose a solution to this discrepancy between observation and climate modeling by investigating the effect of a magma ocean on the atmospheric chemistry of mini-Neptunes. We demonstrate that atmospheric NH3 depletion is a natural consequence of the high solubility of nitrogen species in magma at reducing conditions; precisely the conditions prevailing where a thick hydrogen envelope is in communication with a molten planetary surface. The magma ocean model reproduces the present JWST spectrum of K2-18b to ≲3σ, suggesting this is as credible an explanation for current observations as the planet hosting a liquid-water ocean. Spectral areas that could be used to rule out the magma ocean model include the >4 μm region, where CO2 and CO features dominate: magma ocean models suggest a systematically lower CO2/CO ratio than estimated from free-chemistry retrieval, indicating that deeper observations of this spectral region may be able to distinguish between oceans of liquid water and magma on mini-Neptunes.

The fraction of DL in such relatively small haloes is found to progressively decrease from the high- to the low-mass end, in good agreement with analytic and numerical results from simulations, and in good agreement also with the fraction of the DL observed in the Milky Way and M31. Haloes with different masses have different efficiencies in producing DL:

The DL content in this range of halo mass is the result of stellar stripping due to tidal interaction between satellites and their hosts (95%) and mergers between satellites and the central galaxy (5%), with preprocessed material, a subchannel of mergers and stripping, and so already included in the 100%, that contributes no more than 8% on average. The halo concentration is the main driver of the DL formation: more concentrated haloes have higher DL fractions that come from the stripping of more massive satellites in the high-halo-mass end, while dwarfs contribute mostly in the low-halo-mass end.
On integrable and approximate solutions for Hadamard fractional quadratic integral equations
Authors: Aldosary Saud Fahad , Metwali Mohamed M. A. , Kazemi Manochehr , Alsaadi Ateq
Published: January 2024

This article addressed the integrable and approximate solutions of Hadamard-type fractional Gripenberg's equation in Lebesgue spaces $ L_1[1, e] $. It is well known that the Gripenberg's equation has significant applications in mathematical biology. By utilizing the fixed point (FPT) approach and the measure of noncompactness (MNC), we demonstrated the presence of monotonic integrable solutions as well as the uniqueness of the solution for the studied equation in spaces that are not Banach algebras. Moreover, the method of successive approximations was successfully applied and, as a result, we obtained the approximate solutions for these integral equations. To validate the obtained results, we provided several numerical examples.

Published: February 2024

In this paper, we have constructed a family of three-step methods with sixth-order convergence and a novel approach to enhance the convergence order $ p $ of iterative methods for systems of nonlinear equations. Additionally, we propose a three-step scheme with convergence order $ p+3 $ (for $ p\geq3 $) and have extended it to a generalized $ (m+2) $-step scheme by merely incorporating one additional function evaluation, thus achieving convergence orders up to $ p+3m $, $ m\in\mathbb{N} $. We also provide a thorough local convergence analysis in Banach spaces, including the convergence radius and uniqueness results, under the assumption of a Lipschitz-continuous Fréchet derivative. Theoretical findings have been validated through numerical experiments. Lastly, the performance of these methods is showcased through the analysis of their basins of attraction and their application to systems of nonlinear equations.

Published: January 2024

Carotid plaque classification from ultrasound images is crucial for predicting ischemic stroke risk. While deep learning has shown effectiveness, it heavily relies on substantial labeled datasets. Achieving high performance with limited labeled images is essential for clinical use. Self-supervised learning (SSL) offers a potential solution; however, the existing works mainly focus on constructing the SSL tasks, neglecting the use of multiple tasks for pretraining. To overcome these limitations, this study proposed a self-supervised fusion network (Fusion-SSL) for carotid plaque ultrasound image classification with limited labeled data. Fusion-SSL consists of two SSL tasks: classifying image block order (Ordering) and predicting image rotation angle (Rotating). A dual-branch residual neural network was developed to fuse feature presentations learned by the two tasks, which can extract richer visual boundary shape and contour information than a single task. In this experiment, 1270 carotid plaque ultrasound images were collected from 844 patients at Zhongnan Hospital (Wuhan, China). The results showed that Fusion-SSL outperforms single SSL methods across different percentages of labeled training data, ranging from 10 to 100%. Moreover, with only 40% labeled training data, Fusion-SSL achieved comparable results to a single SSL method (predicting image rotation angle) with 100% labeled data. These results indicate that Fusion-SSL could be beneficial for the classification of carotid plaques and the early warning of a stroke in clinical practice.

Published: January 2024

Background

Hiking is one of the most popular leisure sport activities practiced in the Alps during the summer season, but bears the risk of mountain emergencies, accidents, and fatalities. This paper provides an updated analysis of hiking accidents for the years 2015 to 2021 in the Austrian Alps, thereby outlining fatal and non-fatal accident characteristics.

Methods

For this retrospective analysis, mountain hiking accidents documented by the Austrian Alpine Police during a 7-year period were screened for potential exclusion criteria. The final sample size consisted of 7368 accidents and 7552 victims. The outcome measures were mainly specified by sex, age, injury degree, injury location, pathophysiological characteristics, and cause of injury.

Results

The overall annual number of accidents showed a continuous increase from 428 in 2015 to 544 in 2021. In total, 7.1% of the total victims died during the 7-year period, with male hikers being significantly more affected than female hikers (m: 80.8%, f: 19.2%; p ≤ 0.001). The sex specific distribution for non-fatal hiking accidents was 55.9% in women and 44.1% in men. Male victims showed significantly more frequent cardiovascular events (m: 78.5%, f: 21.5%), multiple injuries (m: 60.2%, f: 39.8%), and wounds/blood loss (m: 57.4%, f: 42.6%) than female victims, whereas women showed more fractures (m: 31.5%, f: 68.5%) than men (p ≤ 0.001). Additionally, men were more likely to injure their abdomen/chest (3.7%), head (14.1%), and multiple body parts (26.5%), whereas women were more likely to injure their ankle or foot (42.3%). Finally, men were more likely to have an accident during the ascent (24.1%), whereas women during the descent (69.0%) (p ≤ 0.001).

Conclusion

This paper provides the latest data and a deeper insight into sex-specific characteristics of mountain hiking accidents in the Austrian Alps.

Published: January 2024

Quantum computing stands as a pioneering field within computer science, leveraging the enigmatic principles of quantum mechanics to execute intricate calculations. At its heart lies the qubit, the elemental building block of quantum information, which resides in a state of superposition, representing both 0 and 1 concurrently. Quantum computers, constructed from assemblies of qubits, inhabit an expansive and intricate 2^n-dimensional complex Hilbert space, with their evolution governed by the Schrödinger equation. The process of quantum computation can be distilled into three key stages:1) Initialization of the input state: Initiating the quantum process; 2)Application of unitary transformations: Executing the desired transformations on the input state; 3) Measurement of the output state. Quantum computers serve as universal machines, capable of decomposing any unitary transformation into a sequence of fundamental gates. This chapter will reveal the importance of quantum mechanics, quantum computation and its applications.

Data refers to raw facts and figures. After processing data, the information is created. Information like facts or statistics that can be recorded, stored, and analysed can be in various forms such as text, numbers, images, audio, or video. The amount of data generated every day in the data-driven world of today makes it nearly difficult to keep it all locally. Cloud services are being used by so many people and businesses to store these massive and hefty volumes of data on cloud servers. Additionally, as the need for cloud computing grows, so does the need for data recovery methods and services. The ability to recover data and information from the backup server when the primary server is down is the primary goal of recovery services and technologies. A secondary server to hold backups for the primary cloud server will be more expensive to add than the primary server itself, which is already quite expensive and time-consuming to build. The goal of this chapter is to provide realistic, cost-effective solutions to this urgent problem.

Authors: Amador Ana Filipa , Pinho Teresa , Martins da Costa Catarina , Madureira António José , Martins Elisabete
Published: February 2024

Cardiac magnetic resonance (CMR) is an established tool for risk stratification in several cardiomyopathies, and its role in muscular dystrophies (MuD) looks promising. We sought to assess how CMR performs in predicting cardiac events in a real cohort of MuD patients. A prospective single-center study with the enrollment of consecutive adult MuD patients referred to cardiac screening from 2012 to 2018 with the collection of clinical and CMR data. During follow-up (FUP), major adverse cardiac events were considered a composite of device implantation, ventricular tachycardia (VT), hospitalization due to heart failure, and death. Sixty-five patients were included (mean age of 32±16, 51% female); the majority had myotonic dystrophy (34; 52.3%); most were asymptomatic (60; 92.3%) and at sinus rhythm (64; 98.5%). CMR was abnormal in 23 (43.3%) patients: left ventricle ejection fraction (LVEF) <55% was found in 7 patients, and late gadolinium enhancement (LGE) was present in 23 patients, mainly intra-myocardial or subepicardial (10 and 8 patients, respectively). During a median FUP of 77 months (interquartile range: 33), there were 7 deaths, 8 implanted devices, and one sustained VT. LVEF<55% and the presence of LGE were associated with the occurrence of all events (log rank test, p=0.002 and p=0.045, respectively). LVEF<55% was associated with a 6-fold higher risk of events (crude hazard ratio of 6.15; 95% confidence interval of 1.65-22.93), that remained significant after adjusting for LGE presence (adjusted hazard ratio of 4.81, 95% confidence interval of 1.07-15.9). In our cohort, CMR LVEF<55% and the presence of LGE were significantly associated with adverse events during follow-up, reinforcing the role of this technique on risk stratification of MuD populations.

Published: February 2024

Background

Spectacles are one of the corrective measures for different errors of refraction. A great proportion of people worldwide are blind due to having a high-refractive error while they neglect using the appropriate corrective measures. The aim is to study the prevalence of noncompliance to spectacle wear and its predisposing factors among adults with refractive errors in Menoufia and Gharbeya Governorates.

Patients and methods

A cross-sectional study performed in Menoufia and Gharbeya Governorates included 290 adults recruited from government and private ophthalmological centers. Data were collected through a predesigned questionnaire asking about personal data, ophthalmological data, measures of compliance, and predisposing factors to noncompliance.

Results

About 38% of the participants were noncompliant to eyeglasses wearing. Among noncompliant, personal causes represented 63.1%, followed by spectacle-related causes (22.5%) and financial causes (14.4%). Rural residence and illiteracy were significantly higher among noncompliant participants. Multivariate analysis revealed that secondary and higher education were independent protective factors against noncompliance.

Conclusion

Noncompliance to spectacle wear was high and was significantly related to rural residence and higher levels of education.

Authors: Chintalwar Vitthalrao Mohan , Neenu N. , Utpat Ketaki , Desai Unnati , Bagul Rahul , Shah Hem , Samuel Magizh
Published: February 2024

ABSTRACT

Pulmonary tuberculosis (TB) sometimes involves regional lymph nodes like mediastinal lymph nodes. These may resolve spontaneously or on treatment; or they may enlarge and result in various complications such as extrinsic bronchial inflammation, ulceration, or rarely erode through the bronchial wall. This erosion is seen radiologically as mediastinal widening or lymphadenopathy with atelectasis and consolidation termed “epituberculosis.” This is more frequently encountered in infants than older children and extremely rarely in adults. We hereby describe a rare case of a 14-year-old girl with mediastinal lymphadenopathy complicating into a bronchonodal fistula and lung abscess formation. A diagnosis of pulmonary rifampicin-resistant TB was obtained on repeated testing of sputum for GeneXpert. The patient was started on appropriate drug-resistant TB therapy and completed therapy successfully.
Oral Health Inequalities among and Within Neo-Marxian Social Classes in South Korea: A Nationwide Cross-sectional Study
Authors: Novrinda Herry , Han Dong-Hun
Published: February 2024

Introduction:

The objectives of this study were to examine the association between the neo-Marxian social class (NMSC) and oral health indicators, to determine the role of mediating factors in social class inequalities, and to assess the relationship between a combination of two subjective indicators and normative dental treatment needs (NDTN) according to the NMSC.

Methods:

Data were from the 4th Korean National Health and Nutrition Examination Survey 2007–2009 with 6710 respondents aged 19–54. The outcomes were self-reported oral health (SROH), self-perceived unmet dental needs (SPUDN), and NDTN. Material (M), psychosocial (PSY), health behavior (HB), and workplace environment were used as mediating factors for SROH and SPUDN. The combination of both outcomes was used in the analysis along with NDTN.

Results:

Non-skilled groups (10%) and petty bourgeoisie (13.2%) had lower proportions of good SROH as well as the highest proportion of SPUDN (48.5% and 48.7%). Further, expert supervisors reported the highest good SROH (22.6%). The M factor (odds ratio [OR] 1.52 [1.24–1.86]) was the highest in several social classes. Managers had a higher probability of SPUDN (OR 1.27 [0.84–1.92]) than the others. Unhealthy patients – except capitalists – had the highest ORs (7.05 [3.89–12.78]), particularly significantly for NDTN. The pattern of the OR was V-shaped, J-shaped, and increasing shape.

Conclusion:

There was non-gradient inequality among Korean workforces. The M, PSY, and HB appeared to play an important role. SPUDN appears to be a better indicator for NDTN and disadvantaged groups among Korean workforces was revealed.

Published: February 2024

Introduction:

Electronic waste (e-waste) poses a growing global concern with significant health and environmental implications. This study examined e-waste awareness among smartphone users in Tanzania's Lake Zone using phones with e-waste components.

Methods:

A cross-sectional study categorized participants into three groups: agricultural farmers, smartphone traders, and livestock keepers. The research took place from May to June 2023, involving a semi-structured interviewer-administered questionnaire that integrated a combination of open-ended and closed-ended questions for data collection. The study investigates e-waste health risk awareness among 288 smartphone users, including 71 business owners, 115 farmers, and 102 livestock keepers. Semi-structured questionnaire was used to gather data on sociodemographics and e-waste-related knowledge, attitudes, and practices). The data were analyzed through two-way analysis of variance.

Results:

Among the 288 surveyed smartphone users, 56.2% (n = 162) were males, 43.8% (n = 126) were females, and 60.1% (n = 173) were young adults aged 18–37 years. Phone usage experience is positively correlated with higher. However, its effects on attitudes (P = 0.148, ŋ² = 0.19) and practices (P = 0.086, ŋ² = 0.24) are relatively smaller. In addition, urban residential location impacts knowledge (P = 0.006, ŋ² 0.15) and attitudes (P = 0.003, ŋ² 0.08) related to e-waste health risks but does not significantly affect e-waste-related practices P = 0.095, ŋ² = 0.09).

Conclusion:

Initiatives should target individuals with limited smartphone exposure, addressing knowledge gaps while considering the geographical context and challenges in both rural and urban areas to improve e-waste awareness.

Published: February 2024

PURPOSE:

The purpose of the study was to report the complications of sutureless intrascleral (SIS) intraocular lens (IOL) fixation and its management.

MATERIALS AND METHODS:

A multicenter, retrospective, consecutive interventional case series of patients with intra or postoperative complications after SIS IOL fixation during the technical learning curve of vitreoretinal surgeons from three Taiwanese referral hospitals. The used surgical techniques were the Scharioth technique for intrascleral tunnel fixation, Yamane technique (double-needle scleral fixation), and modified Yamane technique (double-needle flanged haptic scleral fixation). The IOL models and surgical instruments used as well as each patient’s ocular characteristics and complication management were recorded.

RESULTS:

Of the eight included patients, the complications of 3 (37.5%) and 5 (62.5%) were noted intraoperatively and postoperatively, respectively. Haptic-related complications, including haptic breakage, slippage, and haptic disinsertion, occurred in six eyes. Other complications included uveitis–glaucoma–hyphema syndrome, retinal detachment, and IOL tilt. For the two patients with haptic slippage, repositioning was achieved using a modified cow-hitch technique that resulted in favorable IOL centration and restored visual acuity.

CONCLUSION:

Most complications surgeons encountered during their early exposure to SIS IOL fixation were haptic related. Surgeons should be aware of such complications to prevent and manage them during surgery. Our modified cow-hitch technique could be used to reposition IOLs with unilateral haptic slippage.

Published: February 2024

BACKGROUND

Circulating tumor cell (CTC) count and neutrophil-to-lymphocyte ratio (NLR) are both closely associated with the prognosis of hepatocellular carcinoma (HCC).

AIM

To investigate the prognostic value of combining these two indicators in HCC.

METHODS

Clinical data were collected from patients with advanced HCC who received immune therapy combined with targeted therapy at the Department of Oncology, the Affiliated Hospital of Southwest Medical University, Sichuan, China, from 2021 to 2023. The optimal cutoff values for CTC programmed death-ligand 1 (PD-L1) (+) > 1 or CTC PD-L1 (+) ≤ 1 and NLR > 3.89 or NLR ≤ 3.89 were evaluated using X-Tile software. Patients were categorized into three groups based on CTC PD-L1 (+) counts and NLR: CTC-NLR (0), CTC-NLR (1), and CTC-NLR (2). The relationship between CTC-NLR and clinical variables as well as survival rates was assessed.

RESULTS

Patients with high CTC PD-L1 (+) expression or NLR at baseline had shorter median progression-free survival (mPFS) and median overall survival (mOS) than those with low levels of CTC PD-L1 (+) or NLR (P < 0.001). Meanwhile, patients in the CTC-NLR (2) group showed a significant decrease in mPFS and mOS. Cox regression analysis revealed that alpha-fetoprotein (AFP), CTC PD-L1 (+), and CTC-NLR were independent predictors of OS. The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months (0.821) and 18 months (0.821) was superior to that of AFP and CTC PD-L1 (+).

CONCLUSION

HCC patients with high CTC PD-L1 (+) or NLR expression tend to exhibit poor prognosis, and a high baseline CTC-NLR score may indicate low survival. CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy.
Large isolated fibrous tumors in the upper esophagus: A case report
Authors: Yu Jia-Jia , Pei Huan-Shuang , Meng Yu
Published: February 2024

BACKGROUND

Solitary fibrous tumors (SFT) are rare spindle cell tumors that are usually benign. A total of 10 cases of SFTs in the upper esophagus have ever been reported. Here, we report the anesthetic management of a patient with a large isolated fibrous tumor of the upper esophagus compressing the tracheal membrane. We also provide a literature review of the current research.

CASE SUMMARY

We report the case of a 49 year old male with “cough aggravation and wheezing after exercise”, who underwent esophagectomy for a large isolated fibrous tumor compressing the tracheal membrane in the upper esophagus. We advise the use of a single-lumen tube with a blocker in patients with difficult airways to reduce the incidence of airway injury and fibrinoscopy at all stages of the perioperative period to guide airway management. This case study is the first report of the anesthetic management of a large, isolated fibrous tumor compressing the tracheal membrane in the upper esophagus.

CONCLUSION

This rare case emphasizes the importance of perioperative management of anesthesia in patients with large isolated fibrous tumors of the upper esophagus that compress the tracheal membrane. The use of blocker reduce the incidence of airway injury and fibrinoscopy at the perioperative period to guide airway management.
Case-Based Teacher Training Environment for Pre-service Teachers’ Noticing Skills about Students’ Thinking in Statistical Concepts
Authors: Yılmaz Nadide
Published: January 2024

This study aimed to investigate how pre-service middle school mathematics teachers attend, interpret and respond to the students' thinking about statistical concepts in a case-based teacher training environment. 25 pre-service middle school mathematics teachers participated in the study and they were asked to make evaluations on the cases given. Based on these evaluations, classroom discussions were held on student thinking, the reasons for students’ difficulties and how to overcome these difficulties. The discussions and evaluation reports were analyzed within the framework of professional noticing of children’s mathematical thinking. The results obtained showed that although the pre-service teachers were mostly able to attend to student thinking correctly, these identifications remained superficial. The pre-service teachers were mostly able to interpret student thinking in such a way as to indicate the state of understanding or misunderstanding. When the pre-service teachers’ responding skills were examined, it was revealed that they mostly suggested approaches based on partial conceptual understanding to overcome the difficulties of students. In addition, the results obtained from the study revealed that the pre-service teachers’ noticing skills differed from one case to another.
Voluntary solar radiation exposure and vaginal temperature in slick-haired purebred Senepol and Senepol x Red Angus crossbred heifers
Authors: Sánchez-Rodríguez Héctor L. , Muñiz-Colón Gladycia , Domenech-Pérez Katherine
Published: February 2024

Senepol is a slick-haired Bos taurus breed highly adapted to tropical countries, and their meat is usually low in intramuscular fat. Crossbreeding with breeds more suited to higher marbling scores (e.g., Angus; a wild type-haired breed) may help improve this meat quality trait. However, the question of adaptability to tropical weather in the resulting crossbreeds remains. This study compared the voluntary exposition to direct solar radiation or shade and the vaginal temperatures of slick-haired 50% Senepol - 50% Red Angus (n=5; 50:50), 75% Senepol - 25% Red Angus (n=5; 75:25), and 100% Senepol (n=5; 100:0) heifers in February 2023. Data were analyzed by the GLIMMIX procedure (SAS). The 50:50 heifers recorded lower solar radiation exposure than their 75:25 and 100:0 counterparts at 1100 (P≤0.001), 1115 (P≤0.0003), 1130 (P<0.0001), 1145 (P≤0.004), and 1200 h (P≤0.004). Respective average values of 20,601.40±3,615.03; 32,627.40±4,437.84; and 32,260.40±4,424.65 lx were observed during this period. No differences in vaginal temperature were observed between heifer groups (P=0.8135), with daily averages of 37.27±0.54, 37.23±0.53, and 37.23±0.54 °C for the 50:50, 75:25, and 100:0 heifers, respectively. Heifers with 50% Red Angus blood needed to spend more time under shade during the hottest hours of the day to maintain a body temperature similar to those heifers with greater Senepol influence.

The anti-hyperglycemic activity in ethanolic extracts of mahogany seeds (Swietenia macrophylla king) and medlar leaves (Eriobotrya japonica lindl) have shown to be promising candidates for use in patients with type 2 Diabetes Mellitus due to their high hypoglycemic capacity. In this study, the nutritional composition of the plant material used and a comparison of the effect of ethanolic extracts of mahogany seeds (Swietenia), medlar leaves (Eriobotrya), and metformin on biochemical parameters of hyperglycemic Wistar rats were evaluated. Regarding the nutritional composition, it was found that loquat leaves have a high content of dietary fiber (35 g/100 g bs); while mahogany seed has a good amount of protein (19 %) and lipids (71 %). Swietenia was effective in controlling biochemical parameters of hyperglycemic rats, but at a lower level than metformin. In contrast, Eriobotrya reduced the glucose content, to values without significant differences from the control group in healthy rats. However, the content of cholesterol, triglycerides, and urea; as well as alanine aminotransferase activity, was lower in rats treated with Eriobotrya. In conclusion, both plants are an alternative to control biochemical parameters at normal levels in hyperglycemic individuals.

Authors: Gh. Abdullah Noor , A. Hasso Shahd
Published: February 2024

This paper delves into the realm of steganography, focusing on the evolution of techniques employed to conceal data within digital images. Beginning with an exploration of the motivations behind information security and the role of cryptography, the paper introduces adaptive steganography as a discreet means of incorporating private data into a cover medium. The discussion then shifts to the three key factors in image steganography - resilience, capacity, and imperceptibility - forming the foundation of effective data hiding. The spatial and frequency domain methods are compared, with specific emphasis on the classical Least Significant Bit insertion and more advanced adaptive steganography techniques. The paper further introduces edge-based steganography, highlighting the advantage of manipulating edge areas for increased imperceptibility. Moving beyond definitions and types, the paper provides a comprehensive analysis of notable research works in the field, elucidating their objectives, methodologies, results, strengths, and limitations. The conclusion reflects on the dynamic landscape of steganography, acknowledging both achievements and areas for improvement.
