Facebook addiction: its relation with academic performance of University students
The present study intended to find Facebook addiction and its relation with academic performance of university students from Pakistan. Sample comprised of eighty students (n=80) in total whom are purposefully selected and equally divided according to gender. The universe was public sector higher learning institute named as The Islamia University of Bahawalpur, Pakistan. Cross-sectional survey research design was employed. Data were collected by use of Bergen Facebook addition scale. Data were analyzed from SPSS (21.0), descriptive statistics, correlation and regression analysis were computed to test the hypotheses. Results depict significant negative relationship between Facebook addiction and academic performance of students (β = -.907, t = -4.554). Conclusively, female students consume more time to use Facebook as compare to male students; hence, male students exhibit better academic performance.

Vibration Analysis of Uniform and Tapered Composite Beams with Embedded Shape Memory Alloy
في هذا البحث تم تهجين مواد مركبة باستخدام اسلاك النتنول (نيكل-تيتانيوم). تم تصنيع العينات بتقنية القولبة اليدوية، وتم استخدام راتنج الايبوكسي نوع (Sikadur 52 N) وطبقة من ليف الزجاج ذات الحصيرة المنتظمة، وتم استخدام اسلاك النتنول لتدعيم العينات وبقطر (٠.٥ملم) وبعدد (٠،١،٣ ،٥ و٩) سلك لايجاد تاثير عدد الاسلاك على التردد الطبيعي. العينات تكون على شكل عتبة كابولية مثبتة من طرف وحرة من الطرف الاخر. تمت دراسة تاثير زيادة كل من عدد اسلاك النتنول وقطراسلاك النتنول وطول وسمك العتبة الكابولية على الترددات الطبيعية للعتبة. وكذلك تمت دراسة تاثير ميلان عرض وسمك العتبة الكابولية على التردد الطبيعي. وضحت النتائج زيادة كل من عدد اسلاك النتنول وقطر اسلاك النتنول يؤديان لتقليل التردد الطبيعي في طور المارتنسايت ويؤديان الى زيادة التردد الطبيعي في طور الاوستنايت. كذلك اوضحت النتائج ان زيادة سمك العينة وزيادة نسبة العرض العرض يؤدي الى زيادة التردد الطبيعي. وكذلك زيادة نسبة السمك للعينة يؤدي الى زيادة التردد الطبيعي الاول وتقليل التردد الطبيعي الثاني والثالث. وكذلك زيادة طول العينة يقلل من التردد الطبيعي.In this study, laminated composite materials were hybridized with E-glass fiber and Nitinol (Nickel-Titanium) wires. Hand lay-up technique was used to prepare the samples, epoxy resin type (Sikadur 52 N) was used as matrix reinforced by one fiber from E-glass fiber woven roving with embedded nitinol wires with a diameter 0.5 mm for samples and number of wires such as 0, 1, 3, 5 and 9 to find the effect of the number of wires on the natural frequency. The samples were fixed as a cantilever beam. The effects of increasing the number of nitinol wires, the diameter of nitinol wires, the length of the cantilever beam and the thickness of beam on the natural frequencies of the beam were studied. Also, the effects of the tapered in width side and thickness side on the natural frequencies of cantilever beam were studied. The results showed that the increasing in the number of nitinol wires and the diameter of nitinol wires lead to decrease the natural frequency in martensite phase and increase the natural frequency in austenite phase. Also, the increasing in thickness of beam and width ratio of the beam lead to increase the natural frequency. As well as, the increasing in the thickness ratio leads to increase the first natural frequency and decrease the second and third ones. In addition, the increasing in the length of the beam decreases the natural frequency
Atrazine contamination at the watershed scale and environmental factors affecting sampling rates of the polar organic chemical integrative sampler (POCIS)
AbstractPolar organic chemical integrative samplers (POCIS) were used to estimate atrazine contamination at 24 stream/river sites located across a watershed with land use ranging from 6.7 to 97.4% annual crops and surface water nitrate concentrations ranging from 3 to 5404 μg/L. A gradient of atrazine contamination spanning two orders of magnitude was observed over two POCIS deployments of 28 d and was positively correlated with measures of agricultural intensity. The metabolite desisopropyl atrazine was used as a performance reference compound in field calibration studies. Sampling rates were similar between field sites but differed seasonally. Temperature had a significant effect on sampling rates while other environmental variables, including water velocity, appeared to have no effect on sampling rates. A performance reference compound approach showed potential in evaluating spatial and temporal differences in field sampling rates and as a tool for further understanding processes governing uptake of polar compounds by POCIS
A COMPREHENSIVE STUDY ON RELATIONSHIP OF DIABETES MELLITUS (TYPE 2) AND OBESITY IN PAKISTAN
Introduction: Type 2 diabetes mellitus is one of the most common public health issues worldwide and its incidence is on the rise, particularly in middle-income and low-income countries.
Objectives of the study: The main objective of the study is to analyze the relationship of diabetes mellitus (type 2) and obesity in Pakistan.
Methodology of the study: The cross sectional study was conducted at Allied Hospital Faisalabad during March 2018 till August 2018 The data was collected from 200 diabetic patients who visited the OPD of the hospital. The data was collected through a questionnaire. We assess the nutritional and economic health of patients by asking some survey questions. From the large pool of data we select health status, diet quality, lifestyle, food culture, food security, and demographic information of the selected patients. The economic and health status describe the level of awareness regarding disease.
Results: The data were collected from 200 diabetic patients. We also collect the basic characteristics of patients and compared these values with normal values. So we can find that diseases person have more blood pressure value as compared to normal. The demographical conditions of the patients explains the co-efficient and standard error values. The level of confidence interval is 90 and 95 in this table for the significant value.
Conclusion: It is concluded that T2DM patients require reinforcement of DM education including dietary management through stakeholders (health-care providers, health facilities, etc.) to encourage them to understand the disease management better, for more appropriate self-care and better quality of life

Randomize to Generalize: Domain Randomization for Runway FOD Detection
Tiny Object Detection is challenging due to small size, low resolution,
occlusion, background clutter, lighting conditions and small object-to-image
ratio. Further, object detection methodologies often make underlying assumption
that both training and testing data remain congruent. However, this presumption
often leads to decline in performance when model is applied to
out-of-domain(unseen) data. Techniques like synthetic image generation are
employed to improve model performance by leveraging variations in input data.
Such an approach typically presumes access to 3D-rendered datasets. In
contrast, we propose a novel two-stage methodology Synthetic Randomized Image
Augmentation (SRIA), carefully devised to enhance generalization capabilities
of models encountering 2D datasets, particularly with lower resolution which is
more practical in real-world scenarios. The first stage employs a weakly
supervised technique to generate pixel-level segmentation masks. Subsequently,
the second stage generates a batch-wise synthesis of artificial images,
carefully designed with an array of diverse augmentations. The efficacy of
proposed technique is illustrated on challenging foreign object debris (FOD)
detection. We compare our results with several SOTA models including CenterNet,
SSD, YOLOv3, YOLOv4, YOLOv5, and Outer Vit on a publicly available FOD-A
dataset. We also construct an out-of-distribution test set encompassing 800
annotated images featuring a corpus of ten common categories. Notably, by
harnessing merely 1.81% of objects from source training data and amalgamating
with 29 runway background images, we generate 2227 synthetic images. Subsequent
model retraining via transfer learning, utilizing enriched dataset generated by
domain randomization, demonstrates significant improvement in detection
accuracy. We report that detection accuracy improved from an initial 41% to 92%
for OOD test set.Comment: 29 pages, 9 figure
