Peranan Khalid Bin Walid Dalam Menaklukkan Persia Tahun 634 M
No full textKhalid adalah seorang tokoh Quraisy dan pahlawan yang tak lepas dari
dunia kemiliteran dan peperangan. Khalid termasuk salah satu komandan militer
terkemuka pada abad pertama hijriyah yang tidak pernah terkalahkan dalam
peperangan manapun, baik sebelum maupun sesudah masuk Islam. Khalid bin
Walid merupakan salah seorang sahabat Nabi Muhammad yang terkemuka,
sebagai komandan perang pasukan Islam. Bahkan sebelum masuk Islam Khalid
merupakan salah satu komandan perang pasukan Quraisy. Pada masa
pemerintahan Abu Bakar, peperangan terhadap orang murtad serta penyerbuan ke
Irak dan Syam ditumpukan kepada Khalid bin Al- Walid. Setelah selesai
memerangi orang-orang murtad, Abu Bakar menyuruhnya mengerahkan pasukan
perangnya ke Persia dan Irak. Hasil yang diperoleh adalah kemenangan pasukan
Islam yang berturut-turut menimbulkan banyak ketakutan-ketakutan pasukan
Persia sehingga mereka memilih menyerah.

Walid menaklukkan Persia tahun 634 M dan menganalisis usaha-usaha yang
dilakukan Khalid bin Walid dalam Menaklukkan Persia tahun 634 M.
Manfaat dari penelitian ini adalah bagi almamater sebagai upaya
pengamalan Tri Darma Perguruan Tinggi, bagi peneliti untuk meningkatkan
penguasaan dan kemampuan keilmuannya, terutama yang berkaitan dengan
peranan Khalid bin Walid dalam menaklukkan Persia, dan bagi pembaca
penelitian ini diharapkan dapat menjadi inspirasi dalam penelitian sejenis.Metode yang digunakan dalam penelitian ini adalah metode penelitian
sejarah. Langkah-langkah dalam penelitian sejarah adalahHeuristik, Kritik,
Interpretasi, dan Historiografi. Peneliti menggunakan pendekatan politik serta
menggunakan teori perang.
Kesimpulan dari penelitian menunjukkan bahwa yang melatar belakangi
Khalid bin Walid menaklukkan Persia tahun 634 M adalah adanya perintah
menyebarkan agama Islam untuk semua orang Islam termasuk Khalid dan prestasi
Khalid di dalam dunia militer yang menyebabkan Khalid dipilih sebagai
komandan perang pasukan muslim. Usaha-usaha yang dilakukan Khalid dalam
menaklukkan Persia tahun 634 M adalah melakukan persiapan
penaklukan,menyusun setrategi penaklukan, dan melakukan penaklukan.

The role and the nature of the metabolic rate-temperature curves in lizards from different climatic regions : a comparative study between Chalcides ocellatus (desert species) and Lacerta vivipara (cool-temperature species)
No full textThe metabolic rate-temperature curves of various lizards species different climatic regions were investigated using a double chamber volumetric closed system. Acute oxygen consumption determinations were made, i.e. the animals were not allowed to acclimate to the test temperature. A series of acute M-T curves were obtained. Same species had a low temperature dependence within their M-T curves. These were near the preferred body temperatures. The metabolic rates of cool-temperate species were higher than that of the wane-temperate and desert species of comparable size. The metabolic rate-temperature curves of Chalcides ocellatus and Lacerta vivipara were investigated with respect to body-weight, thermal acclimation effect, total metabolic scope, winter dormancy, photoperiod, effect of feeding and starvation. The weight-specific resting metabolic rate relationship at different temperatures were established for both species. Juveniles and sub-adults of both species were found to have higher rates of oxygen consumption than adults. Partial compensation to cold was observed in L. vivipara and was associated with an upward translation of the metabolic rate-temperature curve in respect to the wanmr acclimated lizards. However, C. ocellatus showed a response to cold acclimation by decreasing its metabolism only at 1CPC. The aerobic and anaerobic scopes were found to be maximal at or near the preferred body temperature (PBT) of both species. The total metabolic scope of both species was found to be maximal at the PBT. However, anaerobic metabolism contributes more to the total scope compared to that of aerobic metabolism, in contrast to L. vivipara, which relies mainly on aerobic metabolism as a major source for Energy.During winter dormancy both adults and sub-adults of L. vivipara were found to have a lower metabolic rate over the temperature range compared to that of summer season. Rates of oxygen consumption in L. vivipara and C. ocellatus initially increased after feeding and then decreased following several weeks of starvation. The effect of photoperiod on the N-T curve of L. vivipara was studied. In most instances the results ficam this research indicated that the metabolic rate-temperature curves of different lizards species were specifically modified and adjusted to the respective climatic regions. Inspecies examined there was found to be a close relationship between the characteristics of the metabolic rate-temperature curves and the ecology of the lizard species.</p

Proposed predictive model for assessing dental clinical performance
No full textTheaim of this article is to present a theoretical model for predicting patients clinical capacity for dental specialties from a practical
point of view. A detailed mathematical model was presented, with several examples of its application. Predicting the exact number
of any clinical capacity is an impossible task due to the complexity of the influencing factors. However, the model can be utilized
with personal customization to provide a predictable educated guess of the clinical capacity for any clinician or specialty. It may
provide useful information for planning, management, and evaluation of dental services.Corresponding Author:

Pattern of malocclusions in saudi arabian patients attending for orthodontic treatment at the college of dentistry, king Saud University, Riyadh
No full textThe prevalence of many orthodontic-related variables was investigated and analyzed in the largest
orthodontic clinic in Saudi Arabia. The results of the study indicate that the majority of the orthodontic
cases were young patients with females showing a marginally higher percentage than males. Class
I molar relationship, permanent dentition, ovoid arch form, crowding, asymmetrical tooth extraction
and asymmetrical arch were found most frequently. A very strong correlation was found between
asymmetrical tooth extraction and the existence of dental arch asymmetry. Cross bite, crowding and
class III molar relationship may be the principal reasons for patients to seek orthodontic treatment.Corresponding Author:
