For precise fertilization of blueberry plants, it is technologically the easiest and most suitable option to use a volumetric filling, for which it can be presumed that it is possible to precisely dose the fertilizer for each plant by grams. For setting up a volumetric filler, it is necessary to know parameters such as the size of the fertilizer particles and their bulk density. The aim of this research is to determine the granulometric parameters and their effect, which is done by measuring up three different fertilizers (SQM Qrop K, Memon Siforga, Substral): width, height, and length of 100 randomly selected fertilizer particles as well as the volumes and weights of 100 particles in 10 repetitions. According to the measurements, the average diameters of fertilizer particles were found as well as the average mass, volumes, and bulk density. A Mahr Digital Caliper 16EWRi 0–150 mm was used to measure the diameters of the fertilizer granules. A Yxlon FF35 computer tomograph was used to accurately scan particles. The analytical scale, Kern ABJ 220-4NM, was used to determine mass. The volumes were measured, using measuring glasses, with one having a maximum volume of 10 mL in 0.2 mL increments and another having a maximum volume of 100 mL in 1 mL increments. Descriptive statistics analysis was performed in Microsoft Excel. It turned out that the average diameters (3.68 vs. 3.64 vs. 4.29 mm) and bulk densities (0.928 vs. 0.631 vs. 0.824 g cm−3) of the three fertilizers differed far from each other, meaning that the given volume could be filled with different amounts of fertilizer. Equations between mass and weight were formed according to the measurements. As a result, it was found that a volumetric filler can be used for fertilizing blueberry plants precisely, but it demands adjusting the filler each time in the situation, which is defined by the variety of blueberry plants: their age, size, and health.

<p><em>B</em><em>rek fish (Barbonymus balleroides) is a consumption, fish that is widely used by people around the River. The population has started to decline, but not yet cultivated. Therefore, research has been conducted as a basis for its domestication, including growth patterns and condition factor of Brek Fish. The total length (TL) of each individual was measured using a digital caliper with an accuracy of 0.05 mm, while the body weight was weighed using an analytical scale with an accuracy of 0.0001 g. the data obtained were analyzed by linear regression found in the microsoft excel program. The results showed that the growth pattern of brek fish was allometric negative, the average condition factor value of brek fish (B. balleroides) was 1.026. The author hopes this research can be used as basic biological information to support the conservation of Brek Fish (B. ballerodes).</em></p>

Macrofungi are diverse in their uses as food and medicine and several species serve as decomposers and also form mycorrhizal associations. Awing forest reserve is diverse in plants and fungi species. However, no work has been carried out to assess the diversity and traditional knowledge of macrofungi in the area. Diversity surveys were carried out in three altitudes using transects of 50×20 m for six months in 2015. Ethnomycology studies were carried out in fifteen communities using focus group discussion, pictorial presentation, and questionnaires. The data was analyzed using descriptive statistics in Microsoft Excel 2010. Seventy-five species belonging to thirty families were identified by morphology. Thirty-six species were found only in the low altitude, 16 in the mid altitude, and 16 species in high altitude. One species was common to low and mid altitude and also low and high altitude; five species were common to mid and high altitude while there was no species common to all three altitudes. The indigenes of the Awing communities commonly called mushroom “Poh” and use it mainly as food and medicine and in mythological beliefs. The most utilized species as food and medicine included Termitomyces titanicus, Laetiporus sulphureus, and Ganoderma sp.

Persamaan Gassmann merupakan hubungan yang digunakan untuk menghitung perubahan kecepatan seismik karena perbedaan saturasi fluida di reservoir. Persamaan Gassmann diterapkan untuk mengevaluasi perubahan kecepatan gelombang seismik (gelombang P dan S). Paper ini bertujuan untuk membahas aplikasi Persamaan Gassmann untuk menganalisis kecepatan seismik menggunakan well data dari wilayah Lapangan Tapti yang terletak di utara-barat laut (NNW) Mumbai dengan variabel perubahan saturasi CO2 dan brine dari 0% sampai 100%. Beberapa diskusi dibutuhkan mengenai asumsi yang terjadi selama substitusi fluida, yakni yakni modulus geser tetap konstan selama proses substitusi fluida, dan jenis fluida yang disubstitusi memengaruhi nilai modulus Bulk (Ksat). Analisis dilakukan menggunakan program MATLAB kemudian dilakukan visualisasi grafik menggunakan Microsoft Excel. Hasil menunjukkan bahwa kecepatan gelombang P (Vp) terhadap saturasi CO2 berkurang dari 0% sampai 30% kemudian bertambah sampai tersaturasi 100%, sementara terhadap saturasi brine berkurang dari 0% sampai 50% kemudian bertambah sampai tersaturasi 100%. Penurunan kecepatan gelombang P (Vp) dikarenakan penambahan saturasi fluida akan menyebabkan Modulus Bulk (Ksat) berkurang. Kecepatan gelombang S (Vs) bertambah seiring substitusi CO2 dan brine. Penambahan kecepatan Vs karena saturasi CO2 lebih signifikan daripada saturasi brine. Penurunan kecepatan gelombang S (Vs) dikarenakan nilai Bulk density berkurang seiring penambahan saturasi fluida, dan nilai modulus gesernya tetap konstan. Nilai densitas berkurang seiring substitusi CO2 dan brine, pengurangan nilai densitas karena saturasi CO2 lebih signifikan daripada saturasi brine. Nilai densitas berkurang dikarenakan volume terisi oleh fluida.

Background: Cost analysis is an effective approach for planners and health system managers to address the issues regarding the increased shortage of resources. Activity-based costing (ABC) is a new system with various applications in daily service activities, the use of which is expanding for the estimation of real costs. Objectives: The present study aimed to calculate the total costs of CT-scan services in Shahid Rajaei Hospital of Qazvin, Iran using the ABC model and compared the results with the tariffs approved in 2016. Methods: This descriptive, applied research was conducted retrospectively. The total costs of CT-scan services were calculated using the ABC model and compared with the tariffs approved in 2016. Data were collected using checklists based on the hospital information system, observations, and interviews. Data analysis was performed in SPSS version 23 and Microsoft Excel software using the non-parametric Wilcoxon test. Results: The total costs of the CT-scan unit in the given year (2016 - 2017) was estimated at 398,380.07 dollars, with the largest share of the total costs in the human resources (57.9%), consumed materials (23.4%), and overhead (18.7%), respectively. No significant difference was observed between the total costs based on the ABC system and tariffs of these services. Conclusions: According to the results, the lack of a difference between the total costs and government tariffs suggested that earnings should be higher than the costs of these services, and these units could become profitable through proper cost control measures.

This study was conducted to examine daily practices of stimulation carried out by mothers at home as an initial support for their children’s language development. This study employed a descriptive design and involved 75 mothers as respondents who wereselected using the non-probability sampling method. The research data were collected using a self-developed questionnaire containing four indicators of early support for children’s language development. The data were analyzed using Microsoft Excel application version 16.10-assisted descriptive statistics. The results of the study showed that daily practices of stimulation carried out by the participants as an initial support for their children’s language development in their first five years of life were included in the ‘very likely’ category. Even so, some practices of stimulation were not properly optimized. This finding promotes the need to increase the ability of mothers to carry out stimulation practices at home so that their involvement in providing initial support for the development of children’s language is more optimal, which in turn can improve the quality of family education at home.
