Assessment of Activity Concentration and Health Hazards of Radiation Exposure in Soil from Mamara Jidda and Waja Tin Mining Sites in Northern Nasarawa State, Nigeria
No full textNatural background radiation exposure is an inevitable occurrence on Earth, and humans are
exposed to radiation in their surroundings whether consciously or unconsciously. However,
increased artisanal and illegal mining could harm the local environment and increase
background radiation levels, affecting the community's overall health. This study assessed the
activity concentration of primordial radionuclides (226Ra, 232Th, and 40K) from soil samples
obtained from Mamara Jidda and Waja tin mine sites in Nasarawa State, Nigeria, and its risk
to human health. The gamma spectroscopy using a Sodium iodide-thallium activated detector
was used to measure the activity concentrations of primordial radionuclides in the surface
soils/sediments samples. The activity concentrations of 226Ra, 232Th, and 40K for Mamara Jidda
and Waja were found to be within the range of 4 - 18 Bq kg-1, 41 - 105 Bq kg-1, and 524 - 717
Bq kg-1; 13 - 40 Bq kg-1, 75 - 134 Bq kg-1, and 591 - 882 Bq kg-1 respectively. The average
values show that 40K and 232Th concentrations are above the recommended limit set by the
United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) in
Mamara Jidda and Waja mine sites. The annual gonadal dose equivalent (AGDE), annual
effective dose rate (AEDE), radium equivalent (Raeq), absorbed dose rate (D), and external
hazard index (Hex) for Mamara Jidda and Waja were found to be 0.56 mSv yr-1, 0.10 mSv yr-
1, 588.58 Bq kg-1, 78.26 nGy hr-1 and 0.46; 0.73 mSv yr-1, 0.13 mS yr-1, 742.74 Bq kg-1, 103.72
nGy hr-1 and 0.61 respectively. The AEDE and Hex are below the recommended safety limits.
However, the high values of AGDE in both mining sites and D in Waja mine demonstrate that
with continuous exposure to radiation, a significant genetic impact is eminent to the miners and
inhabitants of these areas. Also, the Raeq values for both mines suggest that their soils are unsafe
for use as building materials

No full textIlmu Nahwu merupakan bagian yang tidak dapat dipisahkan dalam pembelajaran Bahasa Arab. Pemahaman yang baik terhadap Ilmu Nahwu juga akan berpengaruh pada ketrampilan berbahasa seseorang. Untuk mencapai pemahaman yang baik, diperlukan pula media belajar yang baik sebagai pengantarnya. Buku teks berfungsi sebagai pedoman dasar untuk belajar. Buku teks yang baik akan mempengaruhi kemampuan siswa dalam memahami materi yang disampaikan¸Oleh karenanya ada beberapa hal yang perlu diperhatikan dalam menyusun buku teks yang berkualitas menurut William Frances Mackey yakni seleksi, gradasi, presentasi, dan repetisi materi. Penelitian ini bertujuan untuk mengetahui seleksi, gradasi, presentasi, dan repetisi materi nahwu dalam kitab Silsilah Ta’li@m Al-Lughah Al-‘Arabiyyah dan kitab Mukhtas}ar Jidda@n kemudian menemukan persamaan dan perbedaan dan juga kelebihan dan kekurangan diantara keduanya. Kedua kitab tersebut digunakan dalam pembelajaran nahwu di Madrasah Darul Quran Wal Irsyad.
Penelitian ini merupakan penelitian Library Research. Adapun sumber data utama yang digunakan adalah kitab Silsilah Ta’li@m Al-Lughah Al-‘Arabiyyah dan kitab Mukhtas}ar Jidda@n, sedangkan sumber data pendukung diambil dari buku-buku, artikel, dan literatur yang berkaitan dengen penelitian ini. Metode pengumpulan data yang diterapkan adalah dokumentasi. Metode analisis data yang digunakan penulis adalah metode induktif dan dengan mengacu pada teori William Frances Mackey. Instrumen penelitian yang digunakan adalah lembar observasi berupa table untuk mencatat perbandingan yang ditemukan oleh peneliti.

Perinatal mental health: burden, challenges and prospects
No full textMaternal health has traditionally focused on mortality and physical health morbidity, this approach has inspired several initiatives which significantly enhanced the health outcomes of women in child bearing age globally. More recently, the significance of mental health has become relevant to maternal health and most mental health difficulties of women occur peripartum. An understanding of this problem is valuable to the practice of obstetrics. Method: A non systematic review of the literature was undertaken to identify scholarly works on the subject which was predetermined to answer the issues related to the topic. Conclusion: The mental health problems of women in the perinatal period are huge and growing particularly, in the low and middle income countries. The burden and consequences associated with this group of disorders is borne by the mother, child and the wider society. The global effort in Providing perinatal mental health services to women in a comprehensive and integrated manner has proved difficult due to poor policy, stigma, misconceptions and lack of collaboration. Despite these challenges there is hope in the growing local and global evidence supporting the effectiveness of cheap intervention across diverse economic and social contexts. Integrating mental health into primary health care through the mhGAP, task shifting and interdisciplinary collaboration between obstetricians and mental health physicians can be an important starting point
Jidda: The traditional midwife of Yemen?
No full textContrary to what is assumed, traditional birth attendants (TBAs) do not appear to be clearly defined category of women with specialized knowledge and experience of assistance at deliveries in the local cultural situation at village level in the Anis region of the central highlands in Yemen. In the actual design of training for TBAs in Yemen, this results in problematic provision of basic mother and child health care, in particular safe and clean deliveries to all women at village level.Yemen traditional birth attendant midwife birth-practices childbirth

Two female forms could be distinguished in the available specimens. Form A (Figs. 5–8) sensu K. G. Blair (see New records) is represented by typically coloured females with a completely orange body except of the black metepimeron and two black spots on each elytron, one isolated in the middle and one small at the apex. Female form B (Figs. 1–4) is light red with black middle and hind legs and a black mesepisternum, metepimeron, mesepimeron, metepisternum and metaventrite. The elytra are orange with a black basal band, isolated central spot and black apical spot. The length of metatarsomeres is also different: form A has the 2 nd metatarsomere short and robust (but not flattened from above as in M. bipunctata) and shorter than the 3 rd (Figs. 6–7). Form B has the 2 nd metatarsomere long and slender and almost as long as the 3 rd (Figs. 2–3). Moreover, the species is quite variable in the shape of the elevated process at the apex of pronotum: in form A it is quite distinct and long (Fig. 8), while in form B it is reduced with a small cavity (Fig. 4). Both forms are 6–10 mm long and overlap in their range of distribution. I assume that the morphological and colour differences between both forms are related to their development (possibly different hosts?) and have no taxonomic value. Form C (Fig. 9) is a 4 mm long male, which is completely black with light yellow, basally and apically black elytra (sexual dichroism) and fuscous antennae and tarsal segments; the elevated process at the apex of pronotum is reduced with a small cavity. Biogeography. Macrosiagon elegans belongs to the rather speciose M. ‘ bifasciata ’ species group (BATELKA 2008b), to which also belongs M. fortieri (Chobaut, 1893) described from Egypt. Macrosiagon elegans seems to be more closely related to M. bifasciata (an Eastern Palaearctic and Oriental species) or to M. meridionalis (Costa, 1859) (a Mediterranean species) than to M. bipunctata (with which it occurs sympatrically in Yemen) or to M. fortieri. However, these affinities cannot be proved without a comparison of molecular data of all related species. Distribution.

DESIGN AND CONSTRUCTION OF BABY ROCKING AND MONITORING SYSTEM
No full textThis paper presents the design and construction of a system for a busy parent that will monitor the condition of the infant whether crying or not as well as pacify the baby by rocking and regulating the nearby temperature. The system transmits the baby’s cry in real time to a receiving device which is with the parent, a wooden cradle incorporated with a DC motor pacifies the baby when a sound signal is received. A temperature sensor is also used to monitor the nearby temperature and send the signal to microcontroller which actuate the fan ON/OFF as programed. The system could transmit the baby’s cry in real-time up to 40 meters away from the receiving device. The system also oscillates at 15o when the system is loaded up to 12kg and the load has no effect on the frequency of oscillation.
